GENERAL INFORMATION

Background

Buruli ulcer is a devastating skin disease caused by Mycobacterium ulcerans, a pathogen belonging to thesame family as the organisms that cause tuberculosis and leprosy. Unlike these conditions, however,Buruli ulcer is a poorly understood disease that has emerged dramatically since the 1980s. The causativeagent has unique features and its exact mode of transmission remains unknown. Rapid diagnostic tests arelacking, and surveillance and reporting are poor. Currently, surgery is the principal treatment, but there isincreasing evidence that specific antibiotics would play an important role in the management of thedisease. Early interventions to prevent disabilities are essential in the overall management of the disease.Although it has a low mortality rate, Buruli ulcer frequently causes disabilities, and the costs of treatmentand rehabilitation are prohibitive in the most severely affected areas.

In early 1998, WHO responded to the growing spread and impact of the disease by launching the GlobalBuruli Ulcer Initiative, uniting multiple partners through common goals, technical strategies and agreedprinciples of action. Concerned about the inadequate control of a disease that has such a significant socialand economic impact on poor communities, the Fifty-seventh World Health Assembly (WHA) adoptedResolution WHA57.1 on Buruli ulcer in May 2004 (Annex 2). This resolution called for increasedsurveillance and control of Buruli ulcer and intensified research to develop tools to diagnose, treat andprevent the disease.

Every March, WHO organizes a meeting in Geneva that brings together representatives from theministries of health of affected countries, nongovernmental organizations and researchers currentlyinvolved in Buruli ulcer activities (Annex 2). This meeting is a very important part of global advocacyefforts and provides a forum to share and disseminate new information and coordinate efforts among allpartners. Participation in this meeting has grown annually, and more than 120 people attended the 2004meeting. In accordance with Resolution WHA57.1, WHO will continue to organize this meeting in orderto continue to foster technical cooperation among countries and partners as a means of strengtheningsurveillance, control and rehabilitation activities and promoting research on better diagnostic, treatmentand preventive tools.

Objectives

To share information on progress of control, prevention of disability and research activities.

To review and discuss national action plans and research projects for the year.

To develop strategies for implementing Resolution WHA57.1.

To make recommendations to improve control and research activities.

To promote increased awareness of Buruli ulcer during the annual meeting.

BURULI ULCER PREVALENCE SURVEY IN THE NORTHERNDEPARTMENTS OF BENIN

Dr Christian Johnson

Introduction

Buruli ulcer is known to be widespread in localized foci in 8 out of 12 of Benin’s geographicaldepartments.

The number of cases detected passively has reached 24.2 per 100 000 population in somedepartments where the condition is endemic.

However, there are no data that would enable us to confirm an absence of cases in the fournorthern departments.

In so doing, and in the absence of a properly conducted survey, the fact that there are no data doesnot mean that there are no cases.

The hitherto existing figures on the prevalence of the condition are fragmentary and cannot beextrapolated to the entire country.

This survey has therefore been set in motion to fill the present gap.

Objectives

Overall objective

To document Buruli ulcer in the 4 northern departments of the Republic of Benin.

Specific objective

To confirm whether Buruli ulcer exists in northern Benin.

To determine the prevalence of Buruli ulcer in the four northern departments of Benin.

To provide training on Buruli ulcer to social and health workers in the departments concerned.

Case definitions

Probable indigenous case:

Any person residing in the area surveyed for more than two years, who has not previously lived in anendemic area but has presented with at least one of the under-mentioned lesions: nodule, plaque, oedema,or ulcer that has been active for less than a year.

Clinically confirmed indigenous case:

Any person presenting with the above-mentioned characteristics and whose lesion has been validated by asuitably trained specialist.

Biologically confirmed indigenous case:

Page 10: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

Any person meeting the above-mentioned characteristics and in whom Ziehl-Neelson staining, culture, orPCR have proved positive.

Method

Preliminary training of survey team members;

Family-to-family, door-to-door census;

Notification: only cases fulfilling the definition of a probable indigenous case are to be notified;

Repeat visit by a priority validation team being made to areas where there is a great deal of waterin the ecosystem.

PRELIMINARY FINDINGS OF THE NATIONAL SURVEY ONBURULI ULCER IN THE DEMOCRATIC REPUBLIC OF THECONGO: LESSONS LEARNT

Dr Anatole Kibadi Kapay, Deputy Director, PNLUB, Democratic Republic of the Congo

Summary

In 2004, we carried out a rapid analysis of Buruli ulcer in the 11 provinces of the Democratic Republic ofthe Congo in order to document the situation of the disease and to define a control strategy.

The purpose of the study was to determine the prevalence of Buruli ulcer cases and to identify the mainfoci in the country. The study was conducted in all of the country’s provinces through the provincialcoordinating offices for tuberculosis and Buruli ulcer control.

The findings allowed three types of foci to be identified:

Foci in which the disease is highly endemic: Bas Congo province (cases reported (CR) 110,confirmed cases (CC) 10; Bandundu (CR: 7, CC: 7); Kinshasa (CR: 8, CC: 8); Maniema (CR.46,CC: 4)

Foci in which the disease is endemic: Orientale province (CR: 140, CC: 0); Katanga (CR: 60, CC:1); Equateur (CR: 40, CC: 0); Sud Kivu (CR: 12, CC: 4).

Foci in which the disease is less likely to be endemic: Nord Kivu (CR: 36, CC: 0); Kasaïoccidental (CR: 12, CC: 0); Kasaï oriental (CR: 16, CC: 0).

A total of 487 cases of Buruli ulcer were reported in 2004 during this national survey, 34 of which wereconfirmed on the spot. Partial results of confirmation by the Institute of Tropical Medicine in Antwerpgive 20 confirmed cases out of 101 already analysed.

This first national survey shows that it is possible to determine the prevalence of Buruli ulcer in theDemocratic Republic of the Congo, that the disease is still endemic there and that old foci are still active.

PRELIMINARY RESULTS OF A NATIONAL SURVEY ONBURULI ULCER IN CAMEROON

Dr Alphonse Um Boock, Dr Charles Nsom Mba

Buruli ulcer is an infectious disease caused by Mycobacterium ulcerans. After tuberculosis and leprosy, itis the third most common mycobacterial infection. The pathogen was first described by MacCallum et al.in Australia in 1948, although it had probably already been described by Sir Robert Cook in Uganda in1887.

Endemic foci have been reported in rural areas in more than 30 tropical countries in Africa, Asia,Australia, Mexico, Oceania and South America.

In Cameroon, the disease was first described by Ravisse et al. in 1975 and by Boisvert in 1977 in a focuslimited to the Nyong valley between the villages of Ayos and Akonolinga (Centre province).

In 2001, an epidemiological survey carried out in the Nyong basin under the supervision of the SwissLeprosy Relief Association (Aide aux Lépreux Emmaüs-Suisse (ALES)) led to Cameroon beingclassified among endemic countries in Africa and to recognition of the disease as a public health problem.

Since then, several partners, including ALES, Médecins Sans Frontières Switzerland and the CentrePasteur in Cameroon, have committed themselves to providing the country with technical and financialsupport for case management, which is limited to the districts of Ayos and Akonolinga in Centre province.

However, health workers have continued intermittently to report suspect cases of Buruli ulcer in differentregions of the country, including in the provinces of Extrême Nord, Sud-Ouest and Centre; there has beenno confirmation of these reports by diagnosis.

These observations persuaded ALES and the Ministry of Health of Cameroon, with the assistance of theSwiss Tropical Institute, to carry out a national survey, which was conducted between March andNovember 2004. The first phase of the survey involved identifying areas in which the disease wassuspected. Investigation of suspect cases was based on a questionnaire that was administered in 64% (N =98) of health districts through the leprosy network, which is the most extensive and organized within thehealth system. The results of the first phase showed that there are suspect cases in all of the country’s 10provinces.

The second phase of the survey, which was designed to identify other foci besides Ayos and Akonolinga,made it possible to determine the prevalence of the disease in certain suspect areas, thanks to biologicaland clinical confirmation of Buruli ulcer cases.

The present prospective study covered all the areas that proved suspect during the first phase; othervillages were identified when patients were examined. A workplan was predetermined in agreement withthe district leprosy controllers, the village and health centre chiefs and served as a basis for organizingwork in the field. The population was informed of the arrival of the investigators at least 24 hours inadvance. Activities always began with a health education session focusing on Buruli ulcer, once thepurpose of our presence in the village had been explained.

All patients corresponding to our case definition were included in the study as Buruli ulcer cases, andtheir samples were subjected to laboratory examination for Mycobacterium ulcerans. The patients werequestioned and underwent a clinical examination. A form designed for the study was completed for eachcase; the form contained the following information: patient’s identity, presence or absence of other Buruliulcer cases in the family, level of exposure to risk factors and history of BCG vaccination based on thepresence of the vaccination scar on the inside of the left arm or proof of vaccination (vaccination

certificate). After they had been measured and weighed, each patient underwent a detailed skinexamination to identify and describe, in particular, characteristic Buruli ulcer lesions.

The description and location of lesions, together with any sequelae, were recorded on the form. Thelocation of the lesions was also indicated on a body diagram. The clinical form of Buruli ulcer, classifiedas active or inactive, was recorded in accordance with WHO recommendations.

Swab samples were taken from all patients with an active ulcer. The samples were taken from theundermined edges of the ulcer. A smear was systematically produced after each swab to detect AFB usingZiehl-Neelsen staining at the Centre Pasteur in Yaoundé. Two swabs per patient were systematically keptat at a temperature of 4 °C and sent to the Centre Pasteur in Yaoundé, the reference laboratory, forbacteriological confirmation using PCR, which uses IS2404 published primers (MU5 and MU6) to detectM. ulcerans DNA and by culture of DNA using the otagene extraction kit.

Suspect nodules were systematically excised; one fragment was conserved for pathology and another forbacteriological confirmation.

A dressing was made of any ulcers, and the patients were also given supplies for minor dressings.

Data entry and analysis used EpiInfo 6.0. The Chi-square test was used to determine associations betweendichotomous variables. Continuous variables were analysed using the student’s T test.

A total of 1525 patients living in 167 villages were examined. A total of 705 cases of Buruli ulcer (activeand inactive cases) were registered, of which 84% (N = 590) were active and 16% (N = 115) inactive.

The presence of the disease was confirmed in 6 provinces (Adamaoua, Centre, Sud, Sud-Ouest, Est andExtrême Nord). There were no cases in Nord, Littoral, Ouest and Nord-Ouest provinces. Mbalmayohealth district, in Centre province, is also a major focus of the disease.

With the exception of the Ayos and Akonolinga health districts, Centre province has the highest level ofendemicity, with 49% (N = 342) of all cases registered; it is followed by Est province with 32% (N = 229)and Sud-Ouest province with 11% (N = 76).

The difference between the 0–15-year age group (N = 346) and the above-15-years age group (N = 359) isnot statistically significant (P >0.05). There are significantly more cases among men (52%) than women(48%).

More than 75% (N = 443) of the lesions detected were at the ulcerative stage, and some 5% (N = 30) haddeveloped bone involvement. Early stages and nodules accounted for only 2% (N = 12).

The study showed that 52% (N = 369) of lesions are sited on a lower limb. There are no significantvariations in distribution between men and women (P >0.05).

The average length of time the lesions had evolved since they appeared was 10.3 months (an interval offrom 3 months to 5 years), the median period being 5 months – a sign of the chronic nature of the lesions.

Approximately 93% (N = 549) of patients with active lesions had resorted at least once to traditionalmedicine, in comparison with 21% (N = 124) who had made use of modern medicine.

A BCG vaccination scar was apparent on only 50% (N = 295) of patients with active lesions.

We did not think it worthwhile to carry out the study in Ayos and Akonolinga health districts becausetheir populations are quite well informed about the disease and biomedical case management is wellorganized. In addition, these foci have been in existence for a long time. However, we did include casesconfirmed (N = 225) and registered in these districts during 2004 in the data for national prevalence.

If Ayos and Akonolinga districts are included, prevalence of the disease is 930 cases, 73% (N = 676) ofwhich are active forms.

It is likely that prevalence has been underestimated because of the limited resources and because certainpotentially endemic areas were inaccessible during the rainy season. Additional factors were the poorcollaboration of traditional healers, the bans imposed on some patients by healers and the population’sscepticism about modern medicine, which they consider ineffective.

Although the characteristics of the foci found in Centre province are similar to those described in theliterature – swampy areas liable to flooding – the same is not true of the areas in Adamaoua province, andthis calls for a clarification.

As regards inactive cases, Buruli ulcer is a major cause of mobility deficits and is very often responsiblefor more or less significant disabilities. In most cases, the causes of these disabilities are linked to lack ofproper rehabilitation. Most of them are attributable to lack of mobilization and/or incorrect positioningthroughout the healing and scarring process.

Contractures and skin adhesions are the leading cause of mobility deficits.

Almost 80% of functional disorders were associated with skin problems. In the absence of re-education,success in restoring the functions of the upper limbs is just as mediocre after surgery as after spontaneoushealing or treatment by a traditional healer.

Efforts to limit skin contractures call for specific rehabilitation similar to that required for major burnvictims.

The limits of this preliminary study mean that more precisely focused regional studies are required inorder to determine the actual prevalence of the disease in Cameroon. However, these data provide a soundbasis on which to develop the national programme for control of the disease.

MYCOBACTERIUM ULCERANS INFECTION IN FRENCHGUYANA, 2004

Dr Pierre Couppié, Department of Dermatology, Centre Hospitalier de Cayenne, French Guyana

Surveillance

In 2004, Buruli ulcer was diagnosed in 17 new cases. No relapses were reported. The average age of thepatients was 34 years. The sex ratio was 0.89. Patients were from all geographical origins and socialclasses. Of the 17 patients, 5 were from Brazil. Most cases (14/17) were inhabitants of Cayenne region; 2children from the same family developed the disease. In 2 patients, the lesion was a nodule, in 5 patientsan ulcer without undermined edges and in 10 patients an ulcer with undermined edges. There were nocases of bone involvement. As regards diagnosis: PCR + in 16/16; Ziehl + in 12/16; pathology + (Ziehland/or necrosis) 8/17; Culture + in 5/17.

Special clinical forms

One case concerned an HIV-positive patient in whom Buruli ulcer was diagnosed in 2002 (multiplesubcutaneous nodules on a leg); 5 months’ treatment with rifabutin-clarithromycin, apparent cure after 1year.

Diagnosis

PCR is now routinely offered by the Pasteur Institute in Guyana. Since June 2004, culture has beencarried out in the country (B. Maubert, Institut Pasteur, Guyana).

Epidemiology

Two studies are under way:

Two case control studies: 30 cases and 60 controls, matched by sex, age and period ofconsultation. Subjected to univariate analysis, association between the risk of developingM. ulcerans infection and habitat, activity or leisure in the vicinity of: a river (OR=3.33 [1.06–10.46]); swamp (OR=3.67 [1.31–10.23]); farm (OR=4.40 [1.43–13.54]) or zone liable to flooding(OR=28.0 [3.05–256.7]).

One study to isolate M. ulcerans in the environment; a study is being carried out in the region ofMana (O. Quéré, B. Maubert).

Research projects

Discussions are under way with the Institute for Research and Development to determine the contributionof remote sensing by satellite in order to understand the very sharp variations in the incidence rate fromone year to the next in Guyana. A study to compare case incidence with geographical elements and adynamic study of variations of incidence in time and in relation to flooding could be carried out.

NOTEWORTHY ACTION BY ANESVAD IN 2004 AS PART OFTHE BURULI ULCER CONTROL EFFORT

Verónica Malda

1. Campaign to inform the Spanish public about the disease

2. Projects in the countries affected by the disease

1. Existe.org campaign

Introduction

Informing the Spanish public

The main Spanish NGO engaged in Buruli ulcer control

The only organization to provide information through the mass media. Seventh informationcampaign (to be confirmed)

Objectives

To provide information on Buruli ulcer.

To disseminate the video produced by WHO.

To collect funds for implementing development projects to counter the disease.

Communication strategy

In 2004, WHO produced a documentary on Buruli ulcer that was financed in part by ANESVAD.The purpose of the documentary was to inform the international community about the disease.

In order to publicize the documentary, ANESVAD organized an information campaign about thedisease, together with concrete actions targeting its members and collaborators, the general publicand the mass media.

Buruli ulcer receives little attention in the mass media. The very harsh reality of the disease poseda problem when it came to creating information material. There is a risk in showing things as theyreally are, and it is occasionally counterproductive.

The solution lay in not showing Buruli ulcer itself but rather the effect the disease produces in theeyes of those who see it, thus making it possible for anyone who wants more information to askfor it.

Creative concept

The campaign was intended as a programme to raise awareness by providing Spanish societywith information on Buruli ulcer. To achieve this, a web site was set up within thewww.existe.org domain. The site offered both key information about the disease (its causes,consequences, course, diagnosis and treatment and countries concerned) and allowed users torequest the WHO documentary. The campaign was an active one because it encouraged users tocontact ANESVAD for more information or to request the documentary.

The second step was to draw attention to this web page by a TV advertising campaign. A numberof TV advertisements were designed showing the reactions of different men and women whenthey watched scenes in the WHO documentary showing Buruli ulcer. In order to arouse thecuriosity of viewers, there was no mention of ANESVAD in the sequences; an internet addresssimply appeared at the end: www.existe.org. In the final stage of the campaign, the advertscarried ANESVAD’s signature.

The TV commercials were broadcast for two months (October and November 2004).

The information campaign was bolstered by press and radio advertisements, a banner campaignon the Internet and another direct marketing campaign targeting 1 300 000 people, together with4200 displays in the main Spanish banks.

Results

Difficulties: the disease is very remote for the Spanish public and this means that it is difficult tocapture the attention of the mass media.

A total of 6500 WHO documentaries were distributed.

There were 720 495 hits on the www.existe.org site, with an average of 8.65 pages being visitedby each user.

There were 36 interviews and media appearances.

The campaign had a domino effect through people learning about the campaign and contacting usto organize activities to explain the disease to their immediate circle (leaflets in educationalestablishments, projections of the documentary).

Quantification of the results is difficult because of the absence of concrete indicators formeasuring greater awareness. In ANESVAD’s opinion, this information campaign has had abeneficial effect.

2. Projects in the countries affected

A short presentation of ANESVAD’s action in the main areas of its control strategy:

SURGICAL AND POD TRAINING SUPPORTED BY AMERICANLEPROSY MISSIONS IN ASHANTI REGION, GHANA:CONCLUSIONS FROM A RECENT EVALUATION

Dr Paul Saunderson

Central Ghana is one of the most endemic areas for Buruli ulcer in west Africa. The number of new casesof the disease reported in Ashanti Region is increasing steadily, although this is presumably mainly aconsequence of better reporting; 435 cases were reported in 2004, of which 40% presented as nodules and60% as ulcerative cases; only 224 cases were reported in 2003 and 154 cases in 2002.

After discussions with Dr Pius Agbenorku, a plastic surgeon based in Ashanti Region, and officials fromboth church and government, American Leprosy Missions (ALM) began to fund a programme to trainstaff at district level in the management of the disease. The training focused on teaching doctors to carryout debridement and skin grafting. The project started in 2001 and this evaluation was conducted after 3years of work. The main objective of the programme is “to train doctors and paramedics at the district andcommunity health institutions to manage effectively Buruli ulcer patients in their own health institutions”.Prevention of disability (POD) activities were added to the training in 2003.

The training programme has been effective, in that the number of centers managing Buruli ulcer cases hasdoubled and the quality of care has improved everywhere. Policies and activities aimed at POD are beingslowly implemented. The programme has made significant progress towards its goal.

Recommendations

ALM should continue to support this very worthwhile programme.

There should be a gradual move away from formal courses to structured on-the-job trainingduring supervision visits.

The concepts and strategies of POD should be an integral part of all training.

ALM’s POD Consultant should target the training of local POD facilitators.

THE ASSOCIATION FRANÇAISE RAOUL FOLLEREAU: 10YEARS’ PARTNERSHIP IN BURULI ULCER CONTROL, 1995–2005

Mr Jehan-Michel Rondot

The Association Française Raoul Follereau (AFRF), a major player in leprosy control – its principalactivity – has a high profile in the field and is deeply attentive to the needs voiced by health officials ofcountries where it is present. In 1995, it was asked by Benin and Côte d’Ivoire to help support nationalprojects to provide treatment for Buruli ulcer patients.

In 1998, AFRF helped to organize and finance the Yamoussoukro conference and was one of thesignatories of the final declaration, the founding act of the initiatives that were to follow.

In spite of strong political resolve, there was still uncertainty about the underlying facts of the healthsituation. Specialized knowledge of this “re-emerging” disease was extremely limited and understandingof Mycobacterium ulcerans was poor. However, we rapidly found ourselves having to deal with agrowing number of new cases in areas in which the disease had been declared endemic. These are poorregions, without any health facilities capable of providing case management for barely solvent patientswho are unable to meet the high cost of surgery, which is the only treatment.

AFRF and its Scientific and Medical Commission adopted a clear and pragmatic strategy with threecomplementary objectives: assistance with case management, support for research and awareness.

Its operational support focused on two countries, both of them longstanding partners, Benin and Côted’Ivoire, where, depending on the circumstances, it provides support for private or state centres.

In Benin, starting in 1995 and regularly for 10 years, AFRF has provided its support to the GbémontinCentre in Zou, in the form of medicines and medical supplies (€38 000 earmarked for 2005). This centre,which is run by Sister Julia, was the first to provide treatment for Buruli ulcer patients in Benin. SisterJulia, a brave and pioneering Spanish nun, now appears as a precursor; today, Buruli-ulcer relatedactivities are still an important part of the centre’s work. In 2004, 400 patients were treated there.

The Madeleine and Raoul Follereau Buruli Ulcer Detection and Treatment Centre (BUDTC) wasofficially inaugurated at Pobè in April 2004. This major project marks the response to a request from theMinistry of Public Health and is part of the strategy developed by the national Buruli ulcer controlprogramme. The centre has four wards (26 beds), an outpatient consulting room, an operating theatre anda laboratory. As well as building the centre, AFRF has completely equipped it and covers its runningcosts. Management of the centre is in the hands of Docteur Annick Chauty, who has been at work in Pobèsince the beginning of 2003. In 2004, the budget amounted to €310 000; for 2005, €365 000 have been setaside, including amortization.

Since 1 January 2005, at the request of the Benin Ministry of Public Health, AFRF has contributed€68 000 to the running costs of the Lalo BUDTC, located in Mono Couffo. This centre has 40 beds forpatients and treats 100 patients each year.

In Côte d’Ivoire, assistance from AFRF is directed to the Raoul Follereau Institute in Adzopé, a publichospital run by the Ministry of Health. In 1999, AFRF entered into an agreement to provide casemanagement for 200 patients each year. Since then, its annual contribution has ranged from €100 000 to€115 000. However, activities have been considerably disturbed by the crisis besetting Côte d’Ivoire since2003.

AFRF is very active in the Congo, where for many years it has been the partner of the National LeprosyControl Programme; it has been asked to support the activities of the recently created National BuruliUlcer Control Programme. This new partnership will take shape in 2005.

The second major thrust is support for research programmes: since 1995, the aim of the projects selectedhas been prevention and treatment of the disease thanks to a better understanding of Mycobacteriumulcerans; examples of this are the “M. ulcerans ecology study” and the “Therapeutic trial of clinicallesions of M. ulcerans infections using combined aminoglycoside–rifampicin” by Professor Carbonnelleand Mr Laurent Marsollier of the Angers Medical Faculty (2002–2003) and the “Analysis of theM. ulcerans genome” by Professor Stewart Cole of the Pasteur Institute in Paris. The research budgets for2004 and 2005 amounted respectively to €154 000 and €229 000. For the same purpose, AFRF alsoawards fellowships to young researchers investigating the disease.

Dissemination of information and raising awareness: this complementary element of the strategy adoptedis designed to bring this “mystery” disease to the attention of the general public and to ensure healthworkers have the information they need. To this end, AFRF has provided €60 000 towards the Frenchversions of several publications: Diagnosis of M. ulcerans disease and Management of M. ulceransdisease. It has also jointly produced with WHO a video, The mystery disease. Apart from this, for 10years AFRF has informed and drawn the attention of the French and French-speaking public: itspublications and congresses are an opportunity to put out messages which are taken up by the media. TheBulletin de l’Association des léprologues de langue française (Bulletin of the Association of French-speaking leprologists) – ALLF, which it funds, has published articles on M. ulcerans. As a whole, theseefforts have unquestionably helped to develop national and international awareness and improved ourunderstanding of Mycobacterium ulcerans disease.

In this way, a grand total of over €2 500 000 has been invested since 1995 and testifies to the commitmentof AFRF to Buruli ulcer control in Africa.

The annual meeting at Geneva in April 2005 is an opportunity to show that significant progress has beenmade internationally, although we must still show caution as uncertainties remain. Even though researchis flourishing and shows promise, much about Mycobacterium ulcerans remains unknown, and ourunderstanding of the disease’s epidemiology is still incomplete. Documentation of the socialconsequences of the disease and physical rehabilitation is also scant. AFRF sincerely hopes that in 2005 itwill be possible to optimize both scientific and operational synergies, which guarantee the effectivenessand relevance of efforts in the respective fields. The Association is prepared to contribute to that effort byhelping to galvanize exchange within the network of partners committed to Buruli ulcer control.

CONTRIBUTION MADE BY THE SWISS LEPROSY RELIEFASSOCIATION TO THE BURULI ULCER CONTROL EFFORTIN CAMEROON SINCE 2002

Dr Um Boock Alphonse, Mr René Stäheli

Introduction

The Swiss Leprosy Relief Association (Aide aux Lépreux Emmaüs-Suisse – ALES) has been a valuablepartner in the field of health in Cameroon for almost half a century. Collaboration between ALES and theMinistry of Pubic Health dates back almost 50 years.

Together with its local partners, ALES has succeeded in developing a very effective leprosy controlnetwork in Cameroon, thanks to which the leprosy elimination threshold was attained almost 3 years agoin Cameroon.

Until 2000, ALES had limited its action to leprosy and tuberculosis; after 2000, it extended it to includeBuruli ulcer, starting with the study carried out in the Nyong river basin.

Justification

Study carried out in 2000 in the Nyong river basin under the leadership of ALES in col laborationwith Médecins Sans Frontières Switzerland (MSF-CH).

In 2000, Buruli ulcer was recognized as a public health problem in Cameroon.

Buruli ulcer is caused by a mycobacterium similar to that responsible for leprosy.

Buruli is a neglected disease.

The disease is present in the area of a project supported by ALES.

A request was received from the Ministry of Public health.

Overall objective

To ease the suffering caused by Buruli ulcer at Ayos and Akonolinga.

Specific objectives

To organize treatment for the cases detected.

To support the development of a national Buruli ulcer control programme.

To set up a research programme.

To provide rehabilitation for patients.

Funding

Significant financial support from ALES for the programme since 2002.

FCFA 354 566 007 mobilized over 3 years to organize case management of the disease:

Year 1 (CFA 9,176,674)

Year 2 (CFA 234,626,157)

Year 3 (CFA 110,763,176)

Achievements

Thanks to the funds mobilized, it was possible to attain the above objectives:

Renovation and equipment, provision of a food programme, staff training, transport for patients,educating the populations and research and rehabilitation activities.

Impact of the achievements

Improvement of hospital attendance by patients; a sign of greater confidence.

A marked improvement in the quality of case management.

Health is considered in terms of the classical definition as “a state of complete physical, mentaland social well-being and not merely the absence of disease or infirmity”.

A stimulating working environment for staff.

Overall enhancement of the health system.

Conclusion

The support of ALES has been decisive in organizing case management in Cameroon.

The Ayos and Akonolinga pilot centres provide a valuable opportunity to extend and organizecase management to other sites.

The support of donors is essential because of the programme’s high operating cost.

It would be worthwhile to spread the expertise developed at Ayos to other disease foci.

Prospects

The Ayos pilot project is to be transformed into a regional training centre.

Management tools are to be developed for the programme.

Research activities to improve knowledge of the disease and its treatment are to be developed.

An effort will be made to educate populations about the disease.

Staff from other sites will be trained.

Efforts will be made to improve the equipment used for case management.

IMPLEMENTATION OF EXPERIMENTAL HYPERBARICOXYGEN THERAPY AS TREATMENT FOR BURULI ULCERAT THE ALLADA HOSPITAL IN BENIN

Dr Franco Poggio

At the fourth meeting here in Geneva in 2001, I presented the donation made by my Rotary Club, MilanAquileia, for a hyperbaric oxygen therapy chamber which was intended to speed up cure and to improvetreatment outcomes.

At the time, I said that “it should be done in an African hospital where there is a medical and surgicalteam specialized in treating Buruli ulcer, possessing a well-equipped laboratory for analysis, and ifpossible, a telemedicine link”.

This wish has been fulfilled by the Buruli Ulcer Screening and Treatment Centre (CDT/BU) at Allada.

The hyperbaric oxygen treatment chamber was installed at the hospital, and the Raoul FollereauFoundation of Luxembourg completed the building thanks to the intervention of Professor Kiniffo andDoctor Kohll. Telemedicine facilities are even available at the site.

This has all been made possible by the contributions of the Rotary Club of North Bergamo (whoseChairman, Mr Civettini participated personally on the spot), the San Sirino Rotary Club of Milan and theRotary clubs of Meda, Novare and of New York.

The Italian Navy’s health services, under the command of Admiral Dr Vincenzo Martines, took part inthe project by training three Beninese: a physician, a technician and a nurse at the Consubin diving schoolin La Spezia. We should also like to express our thanks to three Beninese physicians, Dr Roch ChristianJohnson, Dr Ghislain Emmanuel Sopoh and Dr Ange Dossou for their helpfulness.

Two members of the International Scientific Committee who visited Allada last August, ProfessorGiorgio Leigheb and Dr Claudio Clemente, both of whom are Rotarians, will now describe theprogramme that has been set up with the agreement of the Beninese health authorities and theparticipation of WHO, represented by Dr Kingsley Asiedu.

We are committed to participating in the experiment by sending physicians from the Navy (which hasalready sent two naval physicians on mission) specialized in hyperbaric treatment together with volunteerphysicians who are Rotarians, to collaborate with the team of Beninese physicians.

Few studies have shown why patients present late to the hospital after developing Buruli ulcer. Therefore,health-seeking behaviour determinants and stigma were studied by in-depth interviews in patients treatedin the hospital, patients treated traditionally or with active disease and healthy community controlsubjects. Witchcraft was the most common attributed cause of the disease. Other causes mentioned werehygiene, drinking-water and the environment. Self medication and traditional medicine are sought beforepresenting at the treatment centre. A model is shown in which internal and external factors on decision-making are described. With increasing severity, extent and duration of Buruli ulcer, a shift appears tooccur in health-seeking behaviour. Confidence in the hospital and advice of others are important factors.Factors causing delay were the use of traditional medicine before presenting at the treatment centre; thecosts and duration of admission; the disease as considered not serious enough; witchcraft as a perceivedcause of disease; and fear of treatment effects. Patients expected amputation as treatment in the hospital.Stigma among Buruli ulcer patients is huge, with fear of contamination an important contributing factor.This study shows the importance of traditional healing in society. To shorten delay, the hospital should bepromoted as a treatment centre for Buruli ulcer independent of attributed cause. Involving traditionalhealers in health-seeking behaviour should be considered.

Summary

Buruli ulcer is a recognized public health problem in west Africa. In Benin, between 1989 and 2001, theCentre Sanitaire et Nutritionnel Gbemoten (CSNG) treated more than 2500 Buruli ulcer patients. BetweenMarch 2000 and February 2001, field trips were conducted in the Zou and Atlantique regions. The choiceof the two regions was based on the distance from the CSNG and on villages with the highest number ofpatients treated at the CSNG. A total of 66 out of 150 former patients (44.0%) treated at the CSNG werelocated in the visited villages. The recurrence rate of CSNG-treated patients after up to 7 years follow-upwas low (6.1%, CI 95%: 2.0–15.6). We attribute this low rate to the high quality of treatment for Buruliulcer at an accessible regional center (CSNG).

The WHO definition of a recurrent case of Buruli ulcer should be revised to include a follow-up periodlonger than one year.

TREATMENT OF BURULI ULCER WITH THE COMBINATIONOF RIFAMPICIN AND STREPTOMYCIN IN BENIN

Annick Chauty

Until recently, surgical excision was the only available treatment for Mycobacterium ulcerans disease.Following the discovery that treatment with the antibiotic combination rifampicin and streptomycin killsM. ulcerans in early lesions of the human disease after 4 weeks, the role of antibiotics either alone or incombination with surgery for management of all forms of the disease was evaluated in 224 patients. Allpatients were treated with rifampicin (10 mg/kg body weight by mouth daily) and streptomycin (15mg/kg body weight by intramuscular injection daily) for at least 4 weeks on an ambulatory basis underdirect supervision of 12 health centres located in Ouémé and Plateau departments of Benin. Twogroups were defined at week 4: those in whom lesions were healing who continued with antibiotics alonefor another 4 weeks, and those thought to require surgical excision who were referred for surgery whilecontinuing antibiotic treatment for another 4 weeks. The lesions of 99 patients (44.2%) were healedexclusively by antibiotics for a total of 8 weeks, while in 112 patients (50%) referred for surgery theextent of surgical excision was reduced after antibiotics. A large proportion of the patients (211/224:94.2%) were cured with antibiotics for 8 weeks. Interestingly, 31 patients treated for less than 8 weekswere cured with antibiotics only, despite their weak compliance. Among 124 cured patients followed upfor at least 12 months after treatment completion, 2 cases of recurrence were observed with the use ofantibiotics only and another one after antibiotics and surgery. This prospective observational studysuggests that treatment with rifampicin and streptomycin for 8 weeks, as recommended in WHOguidelines, can cure a large proportion of patients with Buruli ulcers. If antibiotic treatment isrecommended for 8 weeks, the optimal duration of therapy is yet to be determined in order to preventrecurrence.

Introduction

Buruli ulcer is caused by Mycobacterium ulcerans. If left untreated, the disease can cause serious skindestruction, scarring, joint contractures and permanent disability. Rarely, amputations and death mayresult. Since it is associated with prolonged and expensive treatment and long term disability, Buruli ulceris suspected to have a large economic impact on the victims, their households and entire communities.However, the total societal costs of Buruli ulcer for Ghana are unknown, and the proportion of Buruliulcer-related costs that are subsidized through the health care system is uncertain.

Methods

In October 2003, we used a survey to retrospectively collect data about socioeconomic, demographic,disease-specific, resource use and disease management characteristics from households affected by Buruliulcer from 1998 to 2003 in three endemic districts of Ghana, Amansie West, Upper Denkyira and Atwima.The survey population included all households in which a household member had been reported to haveBuruli ulcer from 1998 to 2003. A household was defined as a basic social and economic unit where theresidents ate from the same pot. We used a cost-of-illness approach to assess the median annual costs perBuruli ulcer patient by stage of disease to affected households in Ghana. All calculations were convertedfrom Cedis, the local currency, to US$ in 2003. Costs incurred in 2003 were annualized by a constantweight of 4/3, and costs incurred before 2003 were adjusted for time preference using a 3% discount rate.Data were entered into Microsoft Access and t-test comparisons for equality of means of the annual totalcosts by year were performed using STATA.

Results

We enrolled and interviewed people from 390 households in which 468 Buruli ulcer patients resided. Ofthese 468 patients, 57 were excluded from analysis because of incomplete survey responses and 2 wereexcluded based on outlying responses. From the 409 patients included in the analysis, 53% were aged ≤15years, 55% were females, 71% had less than secondary school education and 44% were students. Themedian duration of illness was 3 years; the mean duration of illness for 2003 was 11.3 months (95% CI:11.04–11.52 months).

Page 33: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

27

For 2001–2003, the median annual total costs of Buruli ulcer to a household by stage of disease rangedfrom US$ 76.20 (N = 81) per patient with a nodule to US$ 428 (N = 11) per amputee. Statisticallysignificant differences in the median annual total costs of Buruli ulcer were seen among the specificdisease stages. Based on an average opportunity cost of US$ 2.04 per 6-hour workday for this population,affected households lost between 37.4 (16% of a work-year) and 210 (89% of a work-year) whole work-days per year for a patient with a nodule and amputation, respectively.

Conclusions

Treatment interventions targeting the very early stages of Buruli ulcer would result in lower costs andconsiderable cost savings to households affected by the disease.

BURULI ULCER LABORATORY NETWORK: HOW ADIAGNOSTIC SYSTEM OPERATES IN GHANA

Ohene Adjei, Vera Siegmund, Gisela Bretzel

The Kumasi Centre for Collaborative Research in Tropical Medicine (KCCR)as a Buruli ulcer reference centre

In order to support active case-finding, to allow rapid on-site laboratory diagnosis of Mycobacteriumulcerans disease and to provide accurate laboratory-confirmed incidence and prevalence data, diagnosticlaboratory networks consisting of different level laboratories that collaborate closely with clinical staffand provide training are required in endemic areas.

Presently, the KCCR in Kumasi, Ghana, acts as reference centre for the northern zone including theAshanti region.

Village health workers (volunteers) from Upper Denkyira and Asante Akim North District have beentrained in active early case-finding. The efficiency of case-finding activities in the respective regions hasbeen monitored on a regular basis by KCCR/BNITM staff. Hospital Buruli ulcer teams from AgogoPresbyterian Hospital, Dunkwa Governmental Hospital and St. Martin’s Hospital, Agroyesum (AmansieWest District), have received on-site training in specimen collection according to a standardized systemdeveloped by KCCR/BNITM staff in collaboration with local surgeons and laboratory staff. Specimensand corresponding data forms (designed for the ongoing study) have been collected from the treatmentcentres on average twice a month (depending on the availability of patients) by two KCCR graduatestudents assigned to the Buruli ulcer research group. Diagnostic tests (Ziehl-Neelson, culture, DRB-PCR)have been carried out at KCCR laboratory facilities, quality assurance (Ziehl-Neelson , standard referencePCR) and histopathological analysis for differential diagnosis have been conducted at BNITM.Diagnostic results have been reported to the hospitals and the Ghanaian Buruli ulcer control programmein due course. Laboratory staff from St. Martin’s Hospital has received refresher training in ZNmicroscopy and basic culture techniques at KCCR.

Decentralization of advanced diagnostic tools, i.e. DRB-PCR, in selected laboratories of major treatmentcentres at district level, allows rapid pre-surgical on-site diagnosis of Buruli ulcer, thus ensuring adequatetreatment of laboratory-confirmed disease in the majority of cases. The implementation of DRB-PCRlaboratories for on-site diagnosis in three treatment centres at district level is scheduled for 2005. Hospitalteams (hospital and laboratory staff) from the respective treatment units will receive on-site training insurgical techniques, specimen and data collection, and diagnostic laboratory methods. Following theimplementation of diagnostic methods at district level, KCCR will take over quality assurance for therespective laboratories. Expansion of training activities to additional settings is planned according to therequirements and recommendations of the Ghanaian Buruli ulcer control programme. In addition, toachieve technology transfer to other endemic countries, “training for trainers” workshops in diagnosticlaboratory techniques for laboratory staff from the Democratic Republic of the Congo and Benin will takeplace at KCCR.

Three-step approach to the laboratory diagnosis of Buruli ulcer

Preliminary results from an ongoing study on the DRB-PCR laboratory confirmation of clinicallydiagnosed cases supported by a grant from the Volkswagen foundation suggest the need to revise thecurrent approach to the laboratory diagnosis of Buruli ulcer.

The comparison of the diagnostic sensitivity of DRB-PCR analysis of swab and tissue specimens suggeststhat testing of diagnostic swabs renders a positive diagnosis in over 70% of early ulcerative forms ofM. ulcerans disease, whereas the analysis of tissue specimens provided only an additional 10% of positivediagnostic results. Thus, we conclude that in the majority of early ulcerative cases analysis of non-invasive diagnostic swabs is sufficient to establish the laboratory diagnosis.

Furthermore, based on our previous work, we can safely assume that 30% to 40% of the ulcerative casescan already be diagnosed by swab smear microscopy. In an additional 30% to 40% swab DRB-PCRrenders a positive diagnostic result. Thus, DRB-PCR laboratory confirmation of tissue specimensobtained during surgery shall be required in the remaining approximately 20% to 30% of the cases only.

We also assume that, contrary to the current WHO standards, only one positive diagnostic test issufficient for a positive laboratory diagnosis of Buruli ulcer.

Based on these considerations, a novel three-step approach focusing on non-invasive diagnostic tests forthe optimized, timely, practicable and cost-effective laboratory diagnosis of Buruli ulcer is beingevaluated in Ghana (Figure 1).

For optimum quality of diagnostic specimens, standardized procedures of specimen collection, includingtransport and storage media, have been established as a prerequisite.

Two diagnostic swabs per patient are collected either by village health workers in the field, or by hospitalstaff from patients already presenting at the treatment units.

First, one diagnostic swab is subjected to microscopy in microscopy units at district level, andmicroscopically-positive patients shall subsequently be referred to treatment.

Second, if microscopically negative, the second diagnostic swab is DRB-PCR-tested in hospital DRB-PCR laboratories to be installed in major Buruli ulcer treatment centres. Positive patients are referred tosurgery.

Third, if pre-surgical laboratory tests cannot confirm Buruli ulcer, patients are operated on according tothe surgeon’s indication, and tissue specimens are tested for retrospective laboratory confirmation.Bacteriologically negative specimens may be subjected to histopathology to determine the differentialdiagnosis.

THE ECOLOGY OF MYCOBACTERIUM ULCERANS: AQUATICFOOD WEBS AND WATER QUALITY RELATIONSHIPS

Richard W. Merritt, M. Eric Benbow, R. Kimbirauskas

Mycobacterium ulcerans infection is commonly called Buruli ulcer, a rapidly emerging skin disease thatis often disfiguring and causes severe and lasting morbidity in communities of developing nations.Outbreaks of the disease are nearly always associated with slow-flowing aquatic habitats, which manytimes are affected by, or created from, human-made changes to the landscape. PCR evidence suggests thatthe organism is present in water, biofilm of aquatic plants, detritus, snails, fish and invertebrates.However, the organism has rarely been cultured from the environment. We have proposed a “trophictransmission hypothesis” as a possible transmission scenario for M. ulcerans. With this background, weare trying to determine landscape factors that influence aquatic food web structure and M. ulceransdistribution within and among aquatic habitats of Ghana, Africa. By integrating molecular diagnostictools (PCR), GIS and remote sensing technologies with established ecological sampling and water qualitybioassessment techniques, we hope to determine the ecological distribution and potential factorsinfluencing environmental conditions conducive for M. ulcerans occurrence and distribution at threehierarchical spatial scales: landscape, habitat and community. Using this multi-scale, multidisciplinaryapproach, we will attempt to generate predictive models to enhance the scientific understanding of thisdisease in nature and how the mycobacterium is transmitted in the aquatic environment.

THE COMPLETE GENOME SEQUENCE OFMYCOBACTERIUM ULCERANS STRAIN AGY99

Dr Tim Stinear

The project to determine the genome sequence of a west African epidemic strain of Mycobacteriumulcerans is now complete.

This project was conducted at the Institut Pasteur, Paris, and funded by the Génopole Program of theInstitut Pasteur, the Association Française Raoul Follereau, WHO and the National Health and MedicalResearch Council of Australia.

A genome is the complete DNA sequence of an organism. In simple terms, DNA is a coded set ofinherited instructions made up of four repeating sugar units. These four repeating units link together in anorganism-specific sequence (the so-called DNA sequence) and they contain all the information necessaryfor an organism to live and replicate. Within the DNA sequence are discrete segments called genes. Aspecific gene holds the blueprint for a specific proteinm, and by determining the location of all the genesin a DNA sequence it becomes possible to predict the proteins that the organism will produce.

Bacterial genomes usually contain a single, circular DNA sequence of around 5 000 000 sugar units.Higher order organisms such as humans have genomes 1000 times larger than bacteria and the simplestlife forms, viruses, have genomes 1000 times smaller than bacteria. Importantly, related organisms have arelated sequence of the four DNA sugars. To determine the complete genome sequence of a bacteriummeans to determine the specific order of the 5 000 000 units of the four DNA sugars.

Knowing the complete DNA sequence for a pathogenic bacterium such as M. ulcerans provides keyinsights into its make-up and how it causes disease; it provides the fundamental resource that scientistsuse to develop such things as new diagnostic tests, high discrimination tools for molecular epidemiology,improved antibiotics and vaccines.

For M. ulcerans strain Agy99, we have established that its genome comprises a main circularchromosome of 5 631 606 units (or base pairs) and a smaller circular element (called a plasmid) of174 155 base pairs. The plasmid was a key finding of the project as this element harbours the genesrequired for the production of the M. ulcerans toxin, mycolactone (1). Mycolactone is a key virulencefactor for M. ulcerans.

Analysis of the genome has revealed other insights into this pathogen. It has revealed a genome rich ininsertion sequence elements (ISEs). ISEs are short “parasitic” DNA sequences that perform no essentialcell function but encode a gene that permits the sequence to copy itself. Approximately 7% of the DNAsequence is made up of ISEs. The genome also contains a very high proportion of pseudogenes. These arenon-functional gene sequences caused by DNA mutations. There were 5026 individual genes identified,692 (14%) of which were predicted to be pseudogenes. Such a high level of gene inactivation helpsexplain some of the characteristics of M. ulcerans, such as its slow growth rate. Other features of thegenome include two new mycobacterial viruses, known as prophage, embedded within the genomesequence. In some bacteria, prophage harbour virulence genes, such as those responsible for toxinsynthesis. The impact of the M. ulcerans prophage on the bacterium and their role in disease is as yetunknown.

Computer-based analysis of the genome and its comparison with other mycobacterial genomes hasrevealed at least 20 predicted gene sequences that may produce antigens that are specific for M. ulcerans.These sequences are currently being studied in more detail with the aim of testing their applicability forthe development of a serodiagnostic test for Buruli ulcer.

Page 39: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

33

The structure of the M. ulcerans genome is reminiscent of M. leprae – i.e. a genome in decay –and this isentirely consistent with the hypothesis that M. ulcerans is a pathogen that has evolved to occupy aspecific environmental niche, such as the salivary glands of certain aquatic insects.

The publication of the complete genome sequence is anticipated for 2005 and will provide a solidplatform for accelerating and improving the research effort into this enigmatic pathogen.

THE BURULI ULCER SITUATION IN BURKINA FASO

Dr Christophe Kafando

Background

Until 2003, 30 cases had been reported in the country. However, these figures fail to reflect the truesituation because of the following factors:

Common borders with countries in which the disease is endemic;

A large flow of populations across these borders;

The mainly agricultural and livestock raising nature of the population’s activities;

Existence of many agricultural development projects;

Ignorance of the disease among the population and health workers.

Activities during 2004

Detection

A total of two cases were detected at the dermatology service of Yo university teaching hospital.

Training

A total of 8 surgeons and 60 nurses from health districts located on the border with countries inwhich the disease is endemic were trained to diagnose the disease.

One physician was given training in mapping in March 2004.

One physician took part in the international training workshop on Buruli ulcer held at Yaoundé inJuly 2004.

Information, education and communication

Advocacy to encourage the adoption of a national Buruli ulcer control programme;

As a result, control of the disease has now become a priority in Burkina Faso.

Institutional capacity-building, thanks to the procurement of teaching material.

Difficulties/constraints

A cutback in the size of the team (from 4 to 1) has led to an overload of work, which has made it unableto undertake all the activities at the right moment.

Activities in 2005

Rebuilding the team.

Supervising the health workers trained in 2004.

Drawing up and introducing a national Buruli ulcer control programme.

THE BURULI ULCER CONTROL SITUATION IN CAMEROON

Dr Charles Nsom Mba

Introduction

The disease, which has long been familiar to the indigenous populations and is experienced as a curse, hasbeen identified by the health system. During the past four years, approximately 200 new cases have beendiagnosed each year. The Cameroonian health system is beginning better to recognize the disease inpatients. This has led to an improvement in the national response, with the assistance of partners such asWHO, ALES and Médecins Sans Frontières, who work in the field with our teams providing their supportto Government efforts to control the disease.

Activities carried out at the national level

Adoption of the operational plan at the national coordination meeting at the beginning of the year. Participation in the WHO Advisory Group meeting in March 2004 in Geneva. Organization of a workshop to develop and adopt the technical facilities for each health-care level. Support for the environmental study in collaboration with the Swiss Tropical Institute. Logistic support to Ayos health district (four-wheel drive vehicle). Organization, at Yaoundé, of the International Workshop on Buruli ulcer case management. Organization of the workshop to adapt the guide to case management.

Activities carried out at the operational level

Provision of medical and surgical case management. Training in physiotherapy for staff from the health areas. Organization of information campaigns on the disease for the populations. Participation in the national prevalence survey. Organization of and participation in the field visits (Ayos and Akonolinga) by participants in the

Yaoundé International Workshop on Buruli ulcer case management.

Statistical data

Total number of cases notified: 932 New cases: 914

– 209 (Ayos and Akonolinga)– 705 (remainder of the country, following the national prevalence survey)

Recurrent cases: 18 Forms:

– oedema: 93 (10.04%)– nodules: 73 (6.55%)– ulcers: 700 (75.10%)– plaques: 75 (8.29%)

45

Outlook for 2005

Extension of activities into new disease foci: centre, south, east

Provision of case management Staff training Development of infrastructure Information campaigns Advocacy on behalf of funding Operational research activities

Conclusion

The disease is indeed present in Cameroon and is growing in importance. It is an authentic public healthproblem that is becoming more familiar to the populations and to medical staff. The Government and itspartners are willing to continue with control efforts, with international support and collaboration.

Our thanks are due to the World Health Organization, Aide aux Lépreux Emmauüs–Suisse, MédecinsSans Frontières–Suisse and to the Cameroon Pasteur Centre for their unfailing support for efforts tocontrol Buruli ulcer in Cameroon.

THE BURULI ULCER SITUATION IN THE REPUBLIC OF THECONGO

Dr Damas Obvala

Introduction

In 1970, the first cases of Buruli ulcer in the Congo were detected in the village of Loaka, inKakamoeka district, hence the name Loaka sore;

In 2001, diagnosis of Buruli ulcer was confirmed thanks to a joint MoH/WHO survey;

The disease is endemic in 3 out of 11 departments;

July 2003, adoption of a strategic control plan;

August 2003, training for a pool of physicians/surgeons with the assistance of Professor HenriAssé;

January 2004, creation of a national control programme, attached to the existing leprosy controlprogramme;

July 2004, resumption of BU activities;

Number of patients detected to date: 235;

Lack of suitable case-management facilities.

Activities carried out in 2004

January 2004, creation of the National Buruli Ulcer Control Programme, attached to the existing LeprosyControl Programme.

Organization of the programme

Initial supervisory missions (situation inventory) in departments where the disease is endemic:Kouilou, Niari and Bouenza, in September and November 2004;

Combined mission to provide information, case detection, patient recruitment and follow-up ofcases having undergone surgery in Kouilou department, November 2004;

Supervision of community intermediaries in Kouilou department;

Training for 50 schoolteachers in departments in which the disease is endemic;

Training for 50 community intermediaries in Niari and Bouenza departments;

Provision of surgical treatment for Buruli ulcer at the A. Sicé hospital in Pointe-Noire and thebase hospitals in Nkayi and Dolisie.

Surgery: 44 cases underwent operations, 22 at the A. SICE hospital in Pointe-Noire, 15 at the hospital inNkayi and 7 at the hospital in Dolisie.

ObservationsPrevalence of Buruli ulcer is highest in Kakamoeka district, Kouilou department,followed by Niari and Bouenza.

The above results reflect the activities carried out in 2003 and 2004.

The number of cases is probably higher in the departments in which the disease is known to beendemic.

It is planned to carry out a national prevalence survey in 2005.

Provision of surgical treatment is ineffective; the facilities in which surgery is provided and theirequipment need to be improved.

Difficulties

Most health centres (Makabana and Mouindi-Kakamoeka) are in a poor state of repair;

Vehicles for activities in the field are in short supply;

There is a lack of information, education, communication material to provide communities withmore information;

Shortage of medical and surgical equipment;

Difficulties in providing proper surgical case management for patients (cost of hospital stay,consumables etc).

Page 54: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

48

Suggestions

Rehabilitate and equip the health centres in Makabana, Mouindi and Kakamoeka, to enable themto provide proper case management.

Provide the National Buruli Ulcer Control Programme with a four-wheel drive vehicle forsupervision and follow-up of activities in the three departments.

Provide the teams in the departments with information material for outreach activities, to improvecommunication with the populations.

Provide affordable financial resources to enable programmed activities to be carried out.

ConclusionThere is no doubt that Buruli ulcer is present in the Congo and that it constitutes anauthentic public health problem.

Since July 2004, activities have been effectively revived and resumed.

The bases for proper case management are being laid down.

The implementation of activities is still subject to major constraints.

Our sincere thanks are due to the Global Buruli Ulcer Initiative and to other partners for havingfunded the activities undertaken this year. We take this opportunity also to call for the support ofother development partners to enable us to rehabilitate and equip our health facilities in order toprovide better treatment for our patients.

BURULI ULCER CONTROL IN CÔTE D’IVOIRE

Dr Moussa Diabaté

Presentation of Côte d’Ivoire

Geographical information

Côte d’Ivoire covers an area of 322 465 km² and is bounded to the east by Ghana, to the west by Guineaand Liberia, to the north by Burkina Faso and Mali and to the south by the Atlantic Ocean.

The country is generously watered by four major rivers, which are, from east to west:

the Comoé

the Bandama, on which there are two hydroelectric dams, at Taabo and Kossou

the Sassandra, on which there is a hydroelectric dam at Buyo

the Cavally, which flows along the border with Liberia.

These rivers and their tributaries, together with the reservoirs behind the dams, lagoons and other areas ofstagnant water, are used for agriculture and livestock-raising. The farms attract people, and with them, therisk of outbreaks and spread of water-borne diseases.

Demographic data

Côte d’Ivoire has an estimated population of 16 million, with an average population density of 46inhabitants per km².

The main demographic features are:

Rural population: 69%

Urban population: 31%

Population aged under 15 years: 45%

Average annual growth rate: 3.8%

Social and economic data

Economic situation

The economy relies essentially on agriculture.

Agriculture is heavily turned towards export crops such as cocoa, coffee, cotton, rubber andbananas, etc.

Buruli ulcer: scale and the situation

Epidemiological situation

According to a national survey conducted at the end of 1997, the disease exists on a considerable scale;annual incidence has increased since 1991 and the aggregate number of cases is 10 382. Cases have beennotified in 56 out of 58 departments visited. At the end of 2004, the aggregate number of cases wasapproximately 18 000.

The war has been responsible for large-scale population movements and a number of treatment centresbeing moved. In addition, essential activities to prevent Buruli ulcer have been disturbed; an evaluation ofactivities is therefore called for.

Control activities in 2004

The 2004 Buruli ulcer plan of action had the following objectives:

To increase detection of nonulcerative forms of Buruli ulcer.

To provide clinical case management for Buruli ulcer patients.

To enhance the programme’s management/coordination.

Activities carried out

A training manual on rehabilitation and prevention of disabilities is being prepared by MrFabricio Bonifacio.

Research project on green clay (hydrated aluminium silicate): clinical and therapeutic trial

Buruli ulcer is the subject of several theses.

Fitting out health facilities in Taabo subprefecture: 8 kits, each containing 3 sets of instrumentsfor minor surgery were distributed to Taabo health facility.

Participation in the HealthMapper workshop on Buruli ulcer held on 10–12 March 2004 at WHOheadquarters in Geneva. On completion of the training, it was possible to use the software to mapBuruli ulcer.

Participation in the international workshop on Buruli ulcer case management at Yaoundé(Cameroon). The major recommendations made at this meeting, which took place on 19–23 July2004 at Yaoundé were:

– preparation of a manual on case management of disabilities and physical rehabilitation;– organization, by countries, of training workshops on case management.

External audit of the ANESVAD Foundation’s projects. At the request of the ANESVADFoundation, the Price Waterhouse Cooper auditing firm conducted an external audit of theprojects funded by the foundation. The audit covered projects carried out in 2002–2004. The firmhas not yet submitted its findings.

Constraints:

– The main constraint is the political and military crisis besetting Côte d'Ivoire since September2002.

– Moreover, as a result of the audit requested by the ANESVAD Foundation, all the projectssubmitted to it by DC PNUM have been suspended, reducing coverage to 65.7%.

Actions to be carried out in 2005, expected outcomes and needs

Case detection and awareness-raising activities

Case management activities

Integration, into pilot health facilities, of treatment for Buruli ulcer patients (staff training,equipment)

Adoption of a national treatment protocol

Requests to partners for the rehabilitation and social reinsertion of cured patients

Encouraging research

Encouraging and providing support for theses on mycobacterial ulcers in the medical andpharmaceutical training and research establishments (UFR);

Forming partnerships with national and international research institutions.

Enhancing the Programme's management/coordination

Ensuring the management organization chart is both functional and operational.

Regular supervision and evaluation of activities in the field.

Strengthening links with partners.

Participation in the different national and international meetings on Buruli ulcer.

Expected outcomes

Buruli ulcer is familiar to everyone (the community, partners, political authorities)

Case notification has improved during the year

A Buruli ulcer treatment protocol has been implemented nationally

At least three decentralized Buruli ulcer case management centres are operational

At least two research projects on Buruli ulcer are under way

Management and coordination of the programme have been enhanced.

Needs

Needs are so manifold that we are in the process of identifying priorities per project. An evaluation of theproject by partners is required. The Government of Côte d’Ivoire will lend assistance, but partners will beheavily relied on in order to pool our efforts.

Conclusion

Decentralization of control efforts by building up the human and material capacity of peripheral publichealth facilities and the inclusion of Buruli ulcer in their minimum package of activities is still the majorchallenge that has to be taken up in order to ensure affective and efficient control of this scourge in Côted’Ivoire.

EPIDEMIOLOGICAL SITUATION IN THE DEMOCRATICREPUBLIC OF THE CONGO

Dr Jackie Singa Nyota

The first case to be documented, by Van Oye and Ballion, dates back to 1950 and occurred in Kwiludistrict.

Since that date and until 31 November 2004, some 1000 cases had been confirmed out of a total of morethan 3000 suspect cases (sources: publications, oral communications, reports by health services, etc.) Weshould mention that between 1989 and November 2004, more than 180 confirmed cases were notified inBas-Congo province.

The data collected show only the tip of the iceberg. Buruli ulcer is under-notified in the DemocraticRepublic of the Congo for the following reasons:

the shortcomings of the health system,

the lack of training

the absence of a surveillance system.

Main activities carried out in 2004 (with the support of WHO)

The national survey of Buruli ulcer prevalence, the preliminary findings of which showed that thedisease is hyper-endemic in five regions: Bas-Congo, Bandundu, Equateur, Maniema and theurban province of Kinshasa.

The organization, in September 2004, of the national workshop to draw up and adopt the policyand strategy document, the highlight of which is the integration of Buruli ulcer control activitiesinto existing primary health care by relying, at the intermediate level, on the leprosy andtuberculosis coordination offices (hence the new name CPLT-UB).

The introduction of a surveillance plan and of active case detection in Bas-Congo province inNovember 2004.

The drafting of technical documents on case management (medical, surgical and rehabilitation)and on case confirmation in the Democratic Republic of the Congo, in December 2004.

Development of the training project for Buruli ulcer focal points in the different health areas ofBas-Congo and Bandundu provinces and the urban province of Kinshasa.

The drafting of the 2005–2008 development plan for the PNLUB.

Difficulties encountered

Failure to build up the human and material resources at the intermediate (provincial coordinatingoffices) and peripheral (health area focal points) levels, as a result of which:

a. There is a need for material and financial support to build up human and material capacity.

Page 60: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

54

b. At the peripheral level, there is a need further to reinforce the health areas by designatingcommunity intermediaries in areas in which the disease is highly endemic.

Conclusions and recommendations

In order to reduce the prevalence of Buruli ulcer in the Democratic Republic of the Congo and to preventthe disabilities for which it is responsible, adequate financial and material resources are needed in order to:

determine the actual level of prevalence;

provide case management for patients;

confirm cases;

train medical staff;

inform the population;

introduce a surveillance plan.

Activities planned for 2005

1. Reproduction and dissemination of the policy and strategy document.

2. Building up the capacity of at least four medical facilities to provide case management (at Kinshasa,Bas-Congo and Bandundu).

3. Training for focal points in health areas in three provinces (Bas-Congo, Bandundu and Kinshasaurban province).

4. Organization of the annual meeting on Buruli ulcer in conjunction with the leprosy and tuberculosisprogrammes (September 2005) with the following main themes:

– briefing on the policy and strategy document;– training for leprosy, tuberculosis and Buruli ulcer coordinating officers to enable them to act as

training officers at the provincial level;– determination of prospects for the future by discussing the 2005–2008 development plan.

5. Introduction of the surveillance system:

– information aids– case management– case confirmation– informing the community through community intermediaries.

THE BURULI ULCER SITUATION IN GABON

Dr Louis Bayonne Manou

Buruli ulcer is an endemic disease throughout the subregion and has severe social and economicconsequences.

This explains the need for a cooperation programme between the Ministry of Health and WHO for thepurpose of:

determining the prevalence of the disease and reducing morbidity;

establishing a national Buruli ulcer control programme;

introducing a system of surveillance and setting up facilities to provide case management ofpatients.

Survey protocol

Organization of the survey

A preparatory or pre-survey phase took place in May 2004. The survey proper was carried out in October2004.

Samples

Samples were taken from 43 patients, with two samples being systematically taken from each of them:

One sample was sent to the laboratory at Libreville medical faculty for histopathologicalexamination and Ziehl-Neelsen stain.

One sample was sent to the laboratory of Professor F. Portaels in Brussels for culture and PCR.

Results

Number of samples: 43

Number of results from the laboratory: 35

Positive results: 20 (57%)

Age range: 2–79 years (average age = 48.5 years)

Sex: 11 men; 9 women

REPORT ON BURULI ULCER CONTROL ACTIVITIES INGHANA IN 2004

Dr Edwin Ampadu

Introduction

In 2004, the main activities in Ghana focused on surveillance, capacity development, strengthening ofhealth facilities and advocacy. This report covers the main achievements in these areas.

Surveillance and early detection

Of the 60 targeted endemic districts, 31 regularly report data to the programme. A total of 1157 caseswere recorded from the 31 districts in 7 out of the 10 regions. Ulcerative lesions constituted 66.2% of thetotal cases, the disability rate was 12% and the recurrence rate was 12.4%. Only 3.9% of the cases wereconfirmed by laboratory methods. To improve early detection at the community level, 230 volunteerswere trained in the Upper Denkyira, Ashanti Akim North, Ahafo Ano North and Amansie West districts.

Capacity development

The main focus of capacity development was to implement a multidisciplinary one-week practicaltraining of health workers to improve knowledge and skills in diagnosing and treating Buruli ulcer. Thetraining covers clinical and differential diagnosis, laboratory diagnosis (with emphasis on collection andtransport of specimens to the laboratory), anaesthesia, surgical treatment (with emphasis on excision andskin grafting) and prevention of disabilities. Four training sessions were held during the year; 13 doctorsand 32 nurses from 11 hospitals were trained; 75 patients were treated during these training sessions. TheSasakawa Memorial Health Foundation in Japan also sponsored one doctor for a 6-month training coursein advance plastic surgery. Thanks to the donation of surgical instruments from ANESVAD, all thehospitals where the trainees came from have benefited from this donation.

Surgical review meeting

In June 2004, a mid-year review meeting of the training carried out was held at the KCCR to reviewprogress, identify problems and collectively find solutions to improve future trainings. About 40participants, including the national facilitators and the health workers who participated in the trainingsessions, attended the meeting. The recommendations included a refresher training every 9 months,rotation of training sites to improve the capacity of host hospitals and the need to incorporatephysiotherapy in the management of cases.

Activities

Strengthening the system of surveillance

In 2003, tools for collecting data were developed and introduced. An evaluation of this activity in 2004(in terms of results) showed that most health workers find the data collection tools easy to use, althoughsome difficulties were experienced in completing the forms.

In order to improve case confirmation, the National Buruli Ulcer Control Programme (PNLUB) drew up aguide to taking and sending samples.

In June and October 2004, supervision of control activities was carried out by the central level, togetherwith two joint missions by AGUIRAF in the Forestière region.

Improving the skills of human resources

National level. Training in surgical case management for health workers (7 training workshops).

International level. Participation in international training workshops on Buruli ulcer in the African Regionin Ghana, training in the use of data and mapping for public health purposes at WHO, Geneva, and insurgical case management of Buruli ulcer in Cameroon

SUMMARY OF BURULI ULCER PLANNED ACTIVITIES INSOUTH SUDAN

Dr Abdullahi Ahmed

The main aim of the Buruli ulcer control programme is to expand the interventions for control of Buruliulcer in south Sudan. This is to be done through rehabilitation of health facilities and laboratories forearly detection and management of patients, training of health workers to manage patients effectively,training village volunteers to carry out public awareness campaign and case-findings in the villages.

Goal

The main goal of this proposal is to scale up the Buruli ulcer intervention activities in south Sudan inorder to control the disease.

Objectives

In order to achieve the stated goal above, the following objectives have to be met:

Promote early detection and management of cases.

Standardize case management both surgical and medical.

Ensure that cases of Buruli ulcer are confirmed by laboratory means.

Strengthen the institutions through provision of essential equipment, drugs and dressing materials.

Creating Buruli ulcer awareness in the community by training health workers, school teachersand village volunteers.

Standardize recording and reporting systems for Buruli ulcer cases.

Activities

In order to achieve these objectives, the Buruli ulcer control programme intends to carry out the followingactivities in 2005.

Objective 1: Promote early detection and management of cases

Train one surgeon from Nimule hospital for management of cases. This surgeon will be trained inGhana in surgical and medical management of cases.

Organize one workshop in Nimule for 6 core surgical staff to help the surgeon in surgicalmanagement of cases. These will include the 2 theatre attendants, laboratory technicians, 2surgical ward nurses and 1 clinical officer

Organize one training workshop for 21 health workers drawn from Nimule hospital and fromother health units and centers in Magwi County. These health workers will be trained in

72

recognition of Buruli ulcer, managing simple cases and referral of cases to the hospital. They willalso be involved in Buruli ulcer awareness creation

Objective 2: Standardize case management, both surgical and medical

Develop standardized surgical and medical management protocols in line with WHOrecommended regimens. These will have to be developed in Nairobi in consultation with WHOexperts.

Distribution of these protocols to all hospitals, health centers and units managing Buruli ulcer insouth Sudan.

Objective 3: Ensuring that cases of Buruli ulcer are confirmed by laboratory means

Organize one 3-day refresher training workshop for the laboratory technicians. This will takeplace in Yambio.

Objective 4: Strengthen the institutions through provision of essential equipment, drugs anddressing materials

Renovation of the surgical theatre of Tambura Hospital for emergency major operations androutine minor operations. The major operations in this hospital shall be done by the Yambiosurgeon when he is called upon to do so on patients who cannot be referred to Yambio hospital.

Provision of 8 major surgical kits to the hospitals for surgical operations; 3 major kits each willbe given to Nimule and Yambio hospitals where surgeons will be carrying out operationsroutinely; 1 major kit each will be supplied to Tambura Hospital for emergency operations.

Provision of 22 minor surgical kits to 2 hospitals of Tambura and Nzara and 9 health centres.

Provision of Buruli ulcer drugs, including rifampicin and streptomycin, to all treatment centresand hospitals.

Supply of dressing materials to all health centres and units.

Objective 5: Creating Buruli ulcer awareness in the community

PREVALENCE OF BURULI ULCER DISEASE IN ADJUMANIDISTRICT, UGANDA, IN 2004

Dr Henry Wabinga

Introduction

Buruli ulcer disease is predominant in tropical areas with hot humid climates that are associated withswampy flood-prone landscapes. Adjumani district in north-west Uganda (Fig.1) has this favourableclimate and wetlands suitable for the disease and was known as an endemic area in the 1960s–1970s.However, recently, cases of buruli ulcer have not been reported in this region, which has prompted asensitization workshop to be organized for health workers concerning management of the disease. InJanuary 2004, a sensitization workshop was carried out for health managers of various health unitsthroughout the district, with the aim of improving the knowledge on management of the disease and alsodissemination of standard guidelines to manage this disease.

It was assumed that an improvement in the knowledge of Buruli ulcer by health workers would result inincreasing numbers of cases of the disease being diagnosed in these health units. The aim of thispresentation is to show the impact of this sensitization workshop on the case reporting of Buruli ulcer inAdjumani District.

Methodology

Adjumani district is administratively divided into six subcounties with each subcounty having at least onegovernment health unit capable of diagnosing Buruli ulcer. There are also many health units run bynongovernmental organizations (NGOs).

In June 2004 (6 months after the sensitization workshop), attempts were made to review all records ofhealth centres level III and above (i.e. health units capable of diagnosing Buruli ulcer disease) in thedistrict.

The coordinator of Buruli ulcer activities in Uganda Wabinga, accompanied by a clinical officer, visited 5out of 6 subcounties in the district. The sixth subcounty (Dzaipi) could not be reached because ofinsecurity.

In each health unit, impatient and outpatient registers were retrieved and reviewed and, wherevernecessary, clinical notes were also retrieved. Patients with a diagnosis of Buruli ulcer disease had thedemographic and clinical data analysed.

Results

A total of 10 health units had their records reviewed. Adjumani Hospital, which is a referral hospital, had3 cases diagnosed as Buruli ulcer, all of whom were patients in the hospital at the time of the survey. Thediagnosis was confirmed on PCR in 2 cases. However in the records unit, the record clerks were notclassifying the disease as an entity but rather collectively as skin wounds.

In Ofua health centres, the records reviewed 3 cases.

In Alere health centre, 1 case was recorded. In these two health centers the diagnosis was clinical and ZNstain confirmed. The sociodemographic and clinical data of the 7 cases are presented in Table 1.

Conclusions

Burulu ulcer disease appears to be still a public problem in Adjumani district, and probably the insecuritymay not allow patients to present in health units. There are other health units the study group could notassess as a result of insecurity. It is also strongly believed that buruli ulcer disease in Adjumani district isonly managed by traditional health workers and therefore patients do not seek western medicine. It isrecommended to carry out community diagnosis of the disease to determine its actual prevalence.

HOW TO EVALUATE THE EFFICACY OF HYPERBARICOXYGEN THERAPY (HOT) IN MYCOBACTERIUM ULCERANSDISEASE: THE HOT PROJECT IN THE CDTUB OF ALLADA,BENIN

Giorgio Leigheb,1 Fabrizio Leigheb, Roch Christian Johnson,2 Ghislain Emmanuel Sopoh,3 AngeDossou,3

1University of Eastern Piedmont “A.Avogadro”2National Buruli Ulcer Control Programme, Benin3CDTUB of Allada, Benin

The hyperbaric chamber for the hyperbaric oxygen therapy (HOT) project sponsored by RotaryInternational, Milan Aquileia Club is in function at the CDTUB of Allada in Benin and is hosted in a newbuilding structure built thanks to the help of the Follereau Foundation of Luxemburg.

Now it is time to start with a pilot study to evaluate the efficacy of HOT in the different stages ofMycobacterium ulcerans disease. We suggested a scientific protocol where the patients selected in four(plus one) different groups (in relation to the extension and stage of the disease) are submitted to adouble-blind protocol. In fact, for each group of patients commonly treated with antibiotics therapy plussurgery a randomization is performed obtaining a subgroup of half of the patients to be submitted also toHOT. In this way it is possible to observe, after a standard time (2–6 months), whether a statisticallysignificant improvement of the clinical/histological status is obtained in the subgroup of HOT-treatedsubjects.

We will present in detail the modality screening of the patients, how to choose the patients for each groupand how to perform HOT. We will expose the problems connected to the practical management of thisfascinating research, hoping in this way to improve the recovery of the disease and even to cure manyyoung people affected by Buruli ulcer disease. Our effort with this pilot study represents a very importantgoal: the demonstration of the efficacy of HOT on a good number of cases could suggest the right way tobe followed in the future to beat this terrible disease.

TELEPATHOLOGY: SUPPORT FOR THE HOT (HYPERBARICOXYGEN THERAPY) PROJECT IN THE ALLADA HOSPITALOF BENIN

Dr Claudio Clemente, Casa di Cura S. Pio X, Milan, Italy

Buruli ulcer may simulate, clinically and histopathologically, different non-neoplastic (i.e. pyodermagangrenosun, cutaneous ulcerative tuberculosis, etc.) and neoplastic skin lesions (necrotizing squamouscell carcinoma, ulcerated melanoma, cutaneous lymphoma or sarcoma). In the trial to evaluate theefficacy of HOT in patients with Buruli ulcer, activated by the Rotary Club of Milan Aquileia, theselection of cases is particularly important. No false-positive patient may be included in the trial.Selection must be obtained by:

accurate clinical evaluation (clinical diagnosis supported by photographic documentation)

histopathological diagnosis by biopsy material, confirmed by histochemical stain (Ziehl-Neelsen).

We think that telemedicine/telepathology may be useful when used as a support to select and to acceptcases into the HOT trial for Buruli ulcer. All the patients are documented by digital clinical images; thesurgical specimens (excisions or biopsies) are treated locally by the pathology service of Cotonou, and thehistopathological slides are examined by the local pathologist (Dr Ballè). Digital images (virtual slides)are also produced and sent, together to clinical images, to Milan (Dr Clemente, Servizio di AnatomiaPatologica e Citopatologia, Casa di Cura S. Pio X, Milano, Italy) and Novara (Professor Leigheb, ClinicaDermatologica Università degli Studi del Piemonte Orientale “A. Avogadro” Dipartimento di Scienzemediche Facoltà di Medicina, Azienda Ospedaliera “Maggiore della Carità”) by Internet.

The local equipment, installed in August 2004 in Allada Hospital, and recently verified by thecollaboration of Dr Fabrizio Leigheb and Eng Roberto Rosti, consists of:

a digital camera (Nikon Coolpix 3100) for clinical documentation; clinical pictures are performedbefore, during and after HOT;

an Internet connection;

a digital imaging Nikon Coolscope. This is a microscope/computer that includes all the functionsnecessary for observation, image capture and network communications features. Using NikonCoolscope it is possible to transform a histopathological slide on glass into a digital slide ordigital picture to see remotely by Internet.

All the diagnostic procedures are performed according to WHO guidelines (Portaels F, Johnson P,Meyers WM. Buruli ulcer: diagnosis of Mycobacterium ulcerans disease. Geneva, World HealthOrganization, 2001).

The next step is to carry out pathology services and produce locally the histopathological slides of allspecimens of biopsied patients and to install a satellite connection so that a wide band can be used totransmit the digital slides from Milan. This support is important not only to have a real time clinical andhistopathological diagnosis but also for educational proposals of a continuous learning for the localmedical doctors.

The same microscope and connection will be used by the local pathologist for other different cases forsecond opinions. The goal of this project is not to substitute the local pathologist but to support his workby these new technologies. The Allada pathology service might became a reference point also for otherhospitals in this African area and a good example to reproduce in other countries.

VACUTEX™: A CAPILLARY DRESSING TO IMPROVE THETREATMENT OF BURULI ULCER PATIENTS

Mrs Angela Doran

VACUTEX is a rapid capillary action dressing manufactured by Protex HealthCare (UK) Ltd. Itspatented technology is centred on a three-layer construction, in which one of the two outer polyesterlayers draw exudates/interstitial fluids from the wound surface and transports them into the centralcotton/polyester layer and then subsequently upward into the third upper layer of the dressing. Therefore,VACUTEX is able to debride and deslough the wound, and as a result create the ideal environment forwound healing to take place.

Wounds by their very nature are complex. Therefore, taking into account the additional factor of certainwounds being difficult to treat because of their location, a highly versatile and conformable dressing isrequired for maximum effectiveness.

This point is particularly relevant to the treatment of Buruli ulcer in that both difficult to treat areas andextensive wound sites are common, requiring time-consuming practice and extensive surgery to exciseand then treat further. Often, varying degrees of spacticity and even consequential amputation may be theresult.

Use of VACUTEXas the dressing of choice to assist with debriding and desloughing of Buruli ulcersprior to surgery, and afterwards to enhance the healing environment, may result in much improvedhealing times; plus additional beneficial outcomes, such as improved quality of life, i.e. more spontaneousrecovery and shorter hospital stays and, as a consequence, significant financial benefits.

In conjunction with the Centre de Depistage et de Traitement de l’ulcere de Buruli “le Luxembourg”d’Allada and WHO, Protex HealthCare (UK) Ltd. is sponsoring a comparative trial of VACUTEXdressings versus standard protocol dressings in the treatment of Buruli and other difficult-to-heal ulcers,with the aim of achieving improved patient outcomes, and also cost benefits to health-care providers.

This presentation will encompass the primary features and benefits of VACUTEXand detail some ofthe initial responses to treatment in the form of case studies presented by the medical team from Allada.

THE ROLE OF SURGICAL MISSIONS IN THE MANAGEMENTOF BURULI ULCER IN CÔTE D'IVOIRE

Professor H. Assé, Institute for Reconstructive Surgery, Abidjan, Côte d'Ivoire

By surgical mission, we mean entrusting a team with the task of performing surgical activities for thebenefit of a population that has difficulty attending regular surgical services.

Background

No one remembers exactly when surgical missions began in Côte d’Ivoire.

However, at the national level it was in 1992 that the first local surgical team was formed in order to carryout surgery on a monthly basis at a rural leprosy hospital some 400 km from our service.

In 2001, this strategy was transferred to three peripheral centres providing case management for Buruliulcer.

the Demi Emile Centre (Zouan-hounien)

the St Michel clinic (Zoukougbeu)

the Kongouanou rural dispensary

These centres, which have an operating theatre and sterilization unit provided by ANESVAD, have notrained staff capable of carrying out day-to-day surgery.

So far, it is only thanks to the surgical missions that it has been possible to keep them operational.

Rationale for the surgical missions

Under normal circumstances, in order to organize surgery, the following three fundamental requirementshave to be met:

an operating theatre

a surgical team

patients

A surgical mission is justified by the absence of one of these three elements.

Objectives of the surgical missions

The surgical mission has a three-fold objective:

To provide surgical case management at the local level.

To train local staff to provide proper case management of Buruli ulcer.

Page 85: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

79

To ensure the sustainability of surgical activities by training a local team.

Organization of surgical missions

A surgical mission is divided into three major phases:

Preparation of the mission

Organization of activities in the field during the mission

Post-operational follow-up

In order to improve their quality, it is essential to evaluate these missions.

Results of the surgical missions in Côte d’Ivoire

Between 2001 and 2004, surgical missions made it possible to carry out 932 surgical operations in thethree peripheral centres located in endemic areas, thereby providing local case management.

All the staff at the centres have been trained to provide proper case management of Buruli ulcer.

The average length of stay for ulcerative forms has been shortened to 50 days, thereby improving thepatient turnover rate and achieving rapid reinsertion into society.

However, unfortunately most patients consult at the ulcerative stage.

Besides, surgical skills are not effectively being transmitted because the centres currently have no staffcapable of acquiring such skills.

CLINICAL ASPECTS AND THERAPEUTIC APPROACH TO BURULIULCER SEQUELAE

Professor H. Assé, Dr P. Meredith

Most Buruli ulcer control programmes neglect management of sequelae. This makes it difficult to ensurethe social and professional rehabilitation of patients, most of whom are young.

Proper case management of Buruli ulcer sequelae calls for a sound understanding of the mechanismunderlying their onset, which is dominated by fibrosis and tissue contracture.

Anatomical structures involved

Development of sequelae involves the skin, muscles, tendons, joints and bones.

Conditions determining the onset of sequelae

Several factors contribute to the onset of sequelae. The most important of them are:

Oedema, ulceration, superinfection, the site of the lesion, immobilization, pain, time taken by scarring,unsuitable treatment and absence of physiotherapy.

Classification of sequelae

Buruli ulcer sequelae may be classified into five major groups:

sequelae affecting the skin

sequelae affecting the muscles and tendons

sequelae affecting the joints

sequelae affecting the bones

deformities

Clinical features

Buruli ulcer sequelae affect young patients. They are essentially the consequence of nodular andoedematous forms. The lesions are generally located on the upper limbs. There are several clinicalpictures:

Face and neck: sequelae essentially involve the skin and involve contracture of the loose edges andnatural openings.

Page 87: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

81

Thorax: sequelae affecting the skin involve contractures and disfiguring plaques of scar tissue.

Limbs: the four types of sequelae are found on the limbs and are responsible for severe disabilities.

A number of clinical pictures are worth our attention:

constriction of the thorax and brachia

closure of the thorax and brachia

limited mobility of the elbow

dorsal contracture of the hand

lateral contracture of the hand

stiffness of the knee on extension

limited mobility of the knee

talipes equinus

amputations

Treatment

Treatment has a three-fold purpose:

To prevent the onset of sequelae.

To correct scarring.

To restore function.

Treatment is thus both preventive and curative.

Methods:

restorative surgery

functional rehabilitation

orthosis

Treatment calls for sound coordination of methods and team work.

Treatment calls for authentic commitment by Buruli ulcer control programmes and for a training policyfor plastic surgeons.

THE ROLE OF VOLUNTEER SURGEONS IN BURULI ULCERCONTROL

Dr Rémy Zilliox

The tsunami that unleashed itself on South-East Asia has also affected humanitarian activities,highlighting the numerous shortfalls of the charity-driven process. The magnitude of the disaster, havingdiverted the attention of the entire world towards that continent, has also served to mask other equallyserious disasters in other regions that are completely out of the media spotlight. The funds collected orpledged for this disaster face an uncertain future while there are other more pressing health emergencieselsewhere.

The outpouring of uncoordinated goodwill (and not-so-good will) has led to an inextricable situationwhere kind-heartedness, lack of preparation, incompetence, poor emergency management, proselytism,political competition, lack of respect for local traditions and customs, exaction of leaders and unevendistribution of donations have all been thrown into the same pot in the name of humanitarianism.

This term in itself is inappropriate and obsolete because it emphasizes suffering and is a source ofannoyance to some. So what should it be replaced by? Technical cooperation? Targeted aid? Partnershipin the area of health?

In the small world of Buruli ulcer control, we find the following:

At the local level:

First and foremost, the patient suffering from the disease; and

A health system that does what it can to care for the patient but which is dependent on the State,which imposes political, social and economic restrictions.

At the external level:

First and foremost WHO, whose authority is undisputed and which acts in an advisory andsupportive capacity at the global level;

More or less organized charitable associations with relatively significant financial resources andprofessional paid staff.

In addition, a plethora of goodwill represented as well as can be expected in small agencies orassociations as sanctioned by the 1901 French law.

These men and women, who are aware of the Buruli ulcer situation, want to become involved for anumber of reasons that are not always clear, such as kind-heartedness, altruism, need for a change ofscenery, need to move on after a setback or purely out of scientific interest.

As far as medical and paramedical personnel are concerned, the mere fact of choosing a profession inmedicine involving science and technology is already a sign of altruism.

Page 89: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

83

What can we offer volunteers and what can we do with them?

Volunteers should not get in the way, or be a burden or a source of problems.

They should be useful, efficient and produce results. This implies that they must be trained intheir technical duties and trained to deal with their new environment (cf. Interplast training).

This type of volunteerism, which can be put to good use, must be completely apolitical andreligiously neutral and also respect local structures, usages and customs.

At the same time, volunteers must also be able, as far as possible, to find whatever it is they wereseeking, hence the need for them to be well informed beforehand to avoid any false hopes ordisappointment (no administrative or financial constraints).

A disillusioned volunteer will leave and never come back.

There is a limited number of stakeholders involved in Buruli ulcer control andthis makes anything possible; the question is how?

We propose the following three-pronged approach:

Training and information

Buruli ulcer is not inevitable. Pathogenesis, prevention and treatment have become increasingly wellknown and should be disseminated.

Organization and budgeting

Stakeholders, material and financial resources should be organized optimally as they are few and farbetween. While it is true that the crisis in South-East Asia gave rise to a spectacular display of whatappears to be generosity on an international scale, it is equally true that over the past decade or so,charitable associations have been running on considerably tighter budgets and making do with fewermaterial resources. Everything must be done to optimize financial and human resources.

Ecumenism

All the stakeholders involved in Buruli ulcer control must be united in concerted action and in a spirit ofwholehearted ecumenism. Coordination of all the resources needed to undertake work in this field mustoverride the interests of States, agencies, nongovernmental organizations and charitable associations.Volunteers must be integrated within action as a whole. There is no point in dispersing efforts.

What are the expectations and hopes of the various stakeholders?

First of all, the patient hopes to be treated and cured with a minimum of sequelae and in the best ofconditions (no disorders induced by treatment).

Local health facilities, health-care providers and physicians expect tangible assistance in dealing withlarge numbers of patients with which they are unable to cope: they need medical supplies (dressings,surgical instruments, etc.), technical advice, training and information, and financial resources.

Page 90: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

84

Volunteers, despite their sometimes limited means, do however possess surgical “expertise” that they arewilling to offer to others.

How can we manage these myriad expectations and contingencies while at the same time remainingefficient and cost-effective and putting the interest of the patient first? Who should be responsible forcoordination?

At the workshop held in Yaoundé in July 2004, it was proposed that Buruli ulcer should be dealt with bya “surgical strike” from a WHO task force to assist affected countries. This proposal was made on theunderstanding that the countries concerned would have to participate in financing activities conductedlocally.

BASIC PLASTIC SURGERY SKILLS FORDISTRICT/COMMUNITY DOCTORS TO MANAGE BURULIULCER PATIENTS IN GHANA

P. Agbenorku, P. Saunderson, M. Agbenorku, R. Adator, L. Tuuli, E. Brobbey

Since 1994, the Buruli ulcer patients that were treated at the Plastic and Burns Surgery Unit of the KomfoAnokye Teaching Hospital and the Evangelical Presbyterian Church of Ghana Medical Centre at Krapa-Ejisu (now called Global Evangelical Mission Hospital, Apromase-Ashanti) both in the Ashanti Region,were overwhelming not only in their numbers but especially in their severity and complications. This wasbecause these patients reported very late for treatment. There was therefore the need to adopt a systemwhereby these patients could be seen earlier and preferably in their own local or nearby health institutions.One way to let this happen was to bring training facilities in the management of Buruli ulcer patients tovarious district/community health-care providers. A training workshop in basic plastic surgery skills wasthus designed for the Buruli ulcer endemic districts in the Ashanti Region.

From November 2001 to October 2004, 7 such training workshops were held in 5 hospitals in 5 differentdistricts in the region, with participation from 26 hospitals/health centres drawn from 8 districts in theAshanti Region.

A total of 128 health personnel comprising 34 doctors, 32 medical assistants, 25 anaesthetists, 84 nurses,47 others (disease control officers, administrator, health educationists, etc.) were trained during the 7workshops.

These trainees were to form the core of the so-called Buruli ulcer management teams (BUMTs), whichare now active in 6 of the institutions that participated in the programme.

WHO ESSENTIAL SURGICAL CARE TRAINING TOOLSLINKED TO BURULI ULCER

Dr Meena Nathan Cherian

At primary health-care facilities, there is either lack of or inadequately trained health personnel in theessential surgical procedures and linked equipment. Most often, specialist doctors (surgeons andanaesthesiologists) are not available to perform essential surgical interventions to reduce death anddisability from road injuries, falls, burns, infections, domestic violence and pregnancy-relatedcomplications.

WHO/EHT (Essential Health Technologies) developed a reference manual Surgical care at the districthospital, which addresses the basic surgical and anaesthesia procedures linked to the management ofBuruli ulcer, such as:

Operating room (prerequisites, scrubbing, gowning, skin prep, draping, sterilization, infectionprevention and universal precautions)

Basic principles of wound care

Tissue handling, haemostasis, sutures, cellulitis, abscess

Skin grafting techniques, haemorrhage

Preoperative assessment (anaemia, medical conditions)

Anaesthesia (intravenous access, fluids, ketamine, general and spinal anaesthesia, toxicity,postoperative care)

Postoperative care, pain relief

Cardiopulmonary resuscitation

Oxygen, essential equipment use, maintenance

Quality of care (evaluation, record-keeping, patient consent, referral, team management, bedsideteaching)

WHO/EHT also developed an Integrated management package on emergency and essential surgical care(IMEESC) e-learning tool, meeting the needs of Buruli ulcer training programmes. This tool targetspolicy-makers and health-care providers to provide guidance on WHO recommendations for minimumstandards on emergency and essential surgical care in trauma, obstetrics and anaesthesia at first-referrallevel health-care facilities. The IMEESC tool is being introduced in countries through WHO trainingworkshops, in collaboration with ministries of health, and partners for use in the development of policy,training curricula, emergency equipment lists, needs assessment, and as teaching tools (video, self -earning, PowerPoint slides), best practice protocols for safety of clinical procedures, HIV prevention andin disaster situations.

The Emergency and Essential Surgical Care Project in the Clinical Procedures Unit is a horizontalprogramme and collaborates with other programmes such as Buruli ulcer, HIV, emergency, and maternaland child health.

TRAINING MODULES ON THE MANAGEMENT OF BURULIULCER CONTROL PROGRAMME AT THE HEALTH DISTRICTLEVEL

Dr Alexandre Tiendrebeogo

Justification

Since the launch of the Global Buruli Ulcer Initiative in 1998, WHO has prepared and disseminatedseveral materials for advocacy with national authorities, awareness and sensitization of communities andtraining of health staff. Produced training materials cover diagnostics, case management andrehabilitation of affected patients. However, Buruli ulcer control activities remain in a vertical structure inmost of the endemic countries of the WHO African Region. Suspected cases are often referred to specificservices (reference centres) for laboratory confirmation of diagnosis and for case management, which wasmainly surgical until recently.

Confirmation of the effectiveness of combined antibiotic treatment, and the association of rifampicin andaminosid, opens the way to medical treatment of Buruli ulcer cases, mainly of early forms that are non-ulcerative lesions or small-sized ulcers. Control activities can therefore be integrated in peripheral healthservices, and the district health team must play a key role in organizing and managing Buruli ulcer controlprogrammes in areas endemic for the disease.

For this purpose, the WHO Regional Office for Africa developed training modules on Buruli ulcer controlprogramme management at district level. These modules are to complement other training materials,already available for health staff. They can be used to hold training workshops of district health teams orfor self-learning by Buruli ulcer control programme managers at intermediate or central levels.

Objectives of the training modules

General objective

To contribute to organizing control of Buruli ulcer in countries of the WHO African Region.

Specific objectives

To complement available training material on Buruli ulcer, mainly for medical officers atintermediate and district levels.

To skill district health team members in organizing and managing a Buruli ulcer controlprogramme.

To facilitate the implementation of control activities at district level in endemic countries.

To facilitate the integration of control activities in peripheral-level health services of endemiccountries.

Module 6: Monitoring and evaluation of Buruli ulcer control activities

Module 7: Health staff supervision for Buruli ulcer control

Answer booklet to the module exercises

Glossary booklet for terms and definitions used in Buruli ulcer control

Evaluation booklet (pre and post tests of the workshop)

How to use the modules

The training modules will be produced in the two languages in use in the endemic countries of the WHOAfrican Region (English and French). Two workshops on training-of-trainers will be held: one forEnglish-speaking countries and the second for French-speaking ones. Following these workshops,national trainers will implement a plan of training of health district medical officers and team members ineach country. After being trained, district health teams will be able to set up a diagnostic and managementnetwork of Buruli ulcer cases, train and supervise peripheral-level heath-centre staff, monitor andevaluate control activities within their districts, using the WHO-recommended Buruli ulcer forms.

Conclusion

These training modules will facilitate:

Introducing Buruli ulcer control activities as a public health problem in endemic districts

Integrating Buruli ulcer control activities in general health services at district and peripherallevels in endemic countries.

After implementing the training-of-trainers, training of district health team members and peripheral-levelhealth-care staff, Buruli ulcer control activities will be fully integrated into primary health care ofendemic districts.

INTERACTIVE WEB-BASED LEARNING COURSES ONMYCOBACTERIUM ULCERANS INFECTION

Dr Sunil Deepak

Mycobacterium ulcerans infection, also known as Buruli ulcer, is a reemerging disease that has beenknown to the medical community for a long time and that has caused severe outbreaks in a number ofcountries over the past decade. The launch of the WHO Global Buruli Ulcer initiative (GBUI) in 1998 haspromoted the bringing together of clinicians, experts and research scientists to pool our knowledge ofmanagement of this disease, including diagnosis, differential diagnosis, treatment, prevention ofdisabilities and rehabilitation.

At the same time, there are still many gaps in our knowledge about M. ulcerans infection, some of whichare being investigated and studied so that the existing knowledge is periodically updated.

Several teaching and learning materials on M. ulcerans infection have already been produced, especiallythrough WHO, while some others are under preparation.

The Medical Support Department of the Italian nongovernmental organization, Amici di Raoul Follereau(AIFO), in collaboration with WHO/GBUI, proposes to produce some interactive web-based self-learningmaterials on M. ulcerans infection to supplement the existing teaching and learning materials, withfollowing objectives:

1. To allow any recent gains in knowledge about the disease and its management to be reflected inthe web-based self-learning materials that can be easily modified and updated regularly.

2. To reach health-care providers and researchers in more countries where M. ulcerans infectionmay be unrecognized or under-diagnosed.

3. To promote better learning about the disease through an interactive approach.

Some examples of interactive self-learning materials on M. ulcerans are presented, which can be madeavailable through the Internet (through the WHO AIFO web sites) and though CD-roms. Feedback fromthe field about the materials would be important to improve their quality and usefulness. The materials,initially prepared in English, can be translated into other languages for wider use.

TRAINING OF DOCTORS FROM ENDEMIC COUNTRIES INBASIC PLASTIC SURGERY TO MANAGE BURULI ULCER

Professor Henri Assé

Rationale

Buruli ulcer is a disabling disease that is endemic in rural areas, mainly in poor countries. Treatment ofthe disease, which relies essentially upon surgery, makes use of plastic surgery skills. In Africa, where thedisease is a public health problem, the possibilities for treatment are limited because of the lack of trainedpeople. The few referral centres that exist are unable to provide either early surgical treatment or casemanagement on the spot; these are the only effective strategies for controlling the disease. In order tomake good these shortcomings, it is vital to develop the skills of medical staff by providing them withtraining in basic plastic surgery. This proposed training will also improve the management of otherdisabling diseases endemic in the same areas as Buruli ulcer.

Organization of training

Selection of candidates

Applications for candidates to be submitted by countries (ministry of health and Buruli ulcer controlprogramme). Applications to be examined by WHO. Candidates must meet the following requirements: aqualification in medicine (physician or surgeon); at least one year’s experience managing Buruli ulcer; asigned commitment to serve for at least five years in Buruli ulcer control.

Training centres

Two training facilities need to be identified in Africa; one of them in French-speaking Africa (possiblyCôte d’Ivoire) and the other in English-speaking Africa (possibly Ghana). These centres will provide thegreater part of the training.

European training facility

After theoretical and practical training in Africa in Côte d’Ivoire and Ghana, a course will be held inEurope at a service collaborating with the project. Dr Patrick Meredith of Switzerland, a Swiss plasticsurgeon with interest in Buruli ulcer and the development of plastic surgery in Africa and a member ofthe European Association of Plastic Surgeons, has been charged with selecting the hospitals in Europe.

Duration of training

Although this has yet to be determined, I propose a 12-month training course comprising 9 months’theoretical and practical training in Africa and a 3-month traineeship in a service in Europe.

The rationale for 9 months’ training in Africa is that the trainees will themselves operate upon andmonitor a number of patients in actual field conditions. Training in Europe should be in spring when mostoperations are carried out; in summer, services are often suspended because of holidays.

Outstanding issues

These include the course content, funding and certification.

THE ROLE OF TRAINING IN THE PREVENTION OFDISABILITIES FROM BURULI ULCERMs Valérie Simonet

WHO has defined health as a state of complete physical, mental and social well-being and not merely theabsence of disease or infirmity.

The severe consequences of Buruli ulcer, despite the possibilities offered by surgery, for peoples’participation in everyday activities such as education, social relations, personal hygiene, work, economicactivity etc. have brought WHO to address the question of preventing disabilities caused by the disease.

Accordingly, in 2004, rehabilitation was recognized as one of the three essential elements of Buruli ulcercase management, alongside surgery and treatment with antibiotics.

In Cameroon, at Ayos district hospital in Centre province, Aide aux Lépreux Emmaüs Suisse is providingsupport for a training project to prevent disabilities from Buruli ulcer. Provision of the two main modules(between June and November 2004) made it possible to offer a number of solutions and paths related tothe main features of the training, its specificities, objectives and the requirements in order to attain them.

Some aspects of re-education and rehabilitation relating to Buruli ulcer are quite conventional and arecommon to numerous illnesses: joint mobilization, stretching, building-up muscles, provision ofprostheses, etc. In contrast, treatment of skin involvement is poorly known, with the exception oftreatment of major burns victims in specialized services. Nevertheless, it is the first-line treatment for theprevention of disabilities from Buruli ulcer, which affects essentially the skin. Early use of thesetreatment techniques (skin mobilization, positioning, compressions, apparatus) should, to a large extent,make it possible to avert disabling mobility deficits, which it will often be possible to treat later only bysurgery.

Spectacular success was occasionally achieved after this training course. However, the most importantand radical change lies not in what you can see but rather in what you cannot see. The true hallmark ofsuccessful case management is the absence of disability, which is defined as “discordance between theactivity and status of the individual and the expectations of his or her social environment”.

PREVENTION OF DISABILITY IN PEOPLE WITH BURULIULCER: THE DEVELOPMENT OF A MANUAL FOR FIELDUSE

Linda F. Lehman, Paul Saunderson

Purpose of presentation

This presentation will demonstrate the process and challenges of developing the Buruli ulcer preventionof disability (POD) manual for field use. Observation of existing Buruli ulcer rehabilitation trainingmanuals from several west African programmes focused on rehabilitation efforts appropriate for referralcentres where resources and a highly specialized staff are available. This POD manual was developed toidentify and address problems earlier within Buruli ulcer management programmes preventingcomplications and disability at the field level. The manual is most helpful if it is used in conjunction witha participatory method of training to develop knowledge and skills. Periodic supervision with on-the-jobtraining will be the key to ensuring that POD activities are developed and appropriately implemented.

The manual targets three groups. The first group is health workers who require guidelines forimplementing POD to help them do their job better and avoid common mistakes. The second group ispeople providing supervision and training of others. The last group is programme managers who willensure that POD is an essential component of correct management of Buruli ulcer.

The manual objects are to facilitate health workers and managers to:

understand the importance of early POD action;

identify and document the person’s problems;

determine interventions based on identified problems;

provide the needed interventions to prevent or minimize disability;

teach the person affected by Buruli ulcer and the family how to do self-care;

monitor the response to the intervention and modify as needed;

refer to other specialized services.

This manual was the outcome of reviewing existing documents, observation of patient treatment andlistening to patient, family and health-worker needs and requests in several west African countries from2002 to 2004. The outline of the essentials interventions included in the manual was developed withhealth workers in an Ashanti region POD training in 2003. These essential interventions are neededbefore and after surgery and are summarized as follows:

Health education and self-care training

Wound management

Oedema control

Scar management

“Anti-deformity” positioning and splinting

Page 100: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

94

Management of pain

Exercise and activity to prevent or improve soft tissue and joint contractures

Adaptations in activities of daily living to empower and enable participation and independence

Observations

The implementation and integration of essential POD interventions early within the disease controlprogramme can minimize complications and disability. Success will be determined by the health-careworkers’ and managers’ ability to influence partners, negotiate and advocate policies, teach others toprovide adequate interventions using locally available materials and develop local technology as needed.

Conclusions

The active participation in local, regional, national and international Buruli ulcer health activities areessential for ensuring that both basic and complex POD interventions are integrated and implementedwithin disease programmes. The disease requires a holistic approach, training and supervision,educational and training materials and collaboration between government and nongovernmentalorganizations. Important needs and limited resources encourage partnerships, innovation and acommitment to development.

Introduction

Recent reports suggest that combination antibiotics without or with reduced surgery may be an effectivetreatment for Buruli ulcer. However, there are no studies assessing the economic health benefits of a drugtreatment for the disease. The benefit to an individual of a service or intervention is that individual’smaximum willingness-to-pay (WTP) for it. We estimated the average household WTP for a hypotheticaldrug having a 95% efficacy of treating all stages of Buruli ulcer in three rural, endemic districts of Ghana:Atwima, Amansie West and Upper Denkyira.

Methods

In October 2003, we interviewed the heads of households affected by Buruli ulcer in Atwina, AmansieWest and Upper Denkyira districts about their WTP for a hypothetical drug having a 95% efficacy oftreating all stages of the disease. A household was defined as a basic social and economic unit where theresidents ate from the same pot. An affected household was one in which a household member had beenreported to have Buruli ulcer from 1998 to 2003. Respondents were asked questions about their WTP forthe drug, and about their household’s socioeconomic status, education, and Buruli ulcer diseasecharacteristics. We examined the average change in household WTP for the hypothetical drug by using alinear multivariate model. Independent variables included the districts, levels of education of the heads ofhousehold and Buruli ulcer patients, number of people residing in a household, number of householdmembers with the disease, the patient’s age, sex, stage, location and duration of Buruli ulcer, and a wealthindex that we constructed from an asset list provided by households. We converted all calculations fromCedis to 2003 United States dollars (US$).

Results

We enrolled and interviewed 390 heads of households in which 468 Buruli ulcer patients resided; 39 wereexcluded from the analysis because of incomplete survey responses. The 351 heads of households whowere included in the analysis were willing to pay an average of US$ 157.80 (95% CI: US$ 152.00–163.70)for the hypothetical drug. Heads of households in Atwina and Upper Denkyira districts, but not those inAmansie West district, were willing to pay significantly more than the average for the hypothetical drug,US$ 203.70 (p<0.01) and US$ 225.50 (p<0.0001), respectively. Heads of households with a primary ormiddle school education, but not those without any formal education, were willing to pay significantlymore than the average for the hypothetical drug, US$ 192.00 (p<0.03) and US$ 185.10 (p<0.05),respectively. Heads of households for households having a socioeconomic status below the medianwealth index were willing to pay significantly less than the average for the drug, US$ 183.00 (p<0.05).

Conclusion

The average WTP for a household affected by Buruli ulcer for a hypothetical 95% effective drug wasUS$ 157.80, and varied by socioeconomic status, education and district. These WTP results can facilitatecost-benefit and cost-effectiveness analyses of hypothetical drug treatment strategies for Buruli ulcer.

A FRAMEWORK FOR MEASURING QUALITY OF LIFE INBURULI ULCER PATIENTS

Frank N. F. Dadzie

Introduction

The WHO definition of health as “a state of complete physical, mental and social well-being not merelythe absence of disease…”1 implies that the measurement of health, and health outcomes of interventions,must include not only an indication of changes in the frequency and severity of diseases but also anassessment of the state of well-being associated with health states. This goal can be achieved bymeasuring the improvement or deterioration in the quality of life (QOL) associated with the relevanthealth states. The QOL measurement captures “an individual’s perception of their position in life in thecontext of culture and value systems in which they live, and in relation to their goals, expectations,standards and concerns”. It is a broad ranging concept affected in a complex way by the person’s physicalhealth, psychological state, personal beliefs, social relationships and their relationship to salient featuresof their environment.

Generally, there are satisfactory ways of measuring the frequency and severity of a disease, the outcome(s)of its intervention and the degree of disability it engenders, but there are no generally acceptedinstruments for measuring well-being in terms of QOL changes. The challenge to social scientists is howto develop instruments for measuring the change in QOL that can be adapted to different diseases undervariant conditions, and to generate results that are comparable across different cultural settings.

Quality of life implications of Buruli ulcer

Buruli ulcer typically results in extensive scarring, permanent disability or, in very rare cases, death. Inrecent times, several studies have published prevalence rates of the disease in most of the endemiccountries and communities (e.g. Portaels, 1995; Marston et al., 1995; Asiedu and Etuaful, 1998; van derWerf, 1999; Amofa et al., 2002; Ellen et al., 2003). Other studies continue to investigate theepidemiological and economic burden (e.g. Dadzie, 2001; Mumma et al., 2002, 2003, 2004; Drummond,2004), while still others endeavor to establish the efficacy of drugs in combatting the disease. While theseefforts are laudable, especially in the context of a disease whose mode of transmission is unknown, noefforts are presently expended on capturing the QOL implications of the disease. This paper discusses theneed for measuring QOL changes associated with the various health states of Buruli ulcer, and theframework by which QOL may be measured.

The need to measure the QOL of Buruli ulcer patients derives from the debilitating outcomes that itspatients continue to endure in the various health states of the disease. While it rarely kills its patients,Buruli ulcer confers various forms of disability and functional limitations on its patients. Thus, the livesof the patients are affected in complex ways that can be captured as a multi-dimensional index that couldbe used to measure and monitor the effect of the disease on patients’ well-being. Such a measure of well-being would have the following other uses:

serve as a basis for selecting interventions provide a framework for monitoring QOL changes for a given population at risk for Buruli ulcer; identify inequalities in the QOL of patients in different health states of the disease; the result would be used for cost utility analyses.

The framework

The health outcomes of any disease may be classified into: a) health-related outcomes, and, b) non-health-related outcomes. For Buruli ulcer, the health-related outcomes include scarring, functional limitations,disability and, in very rare cases, death. The non-health-related outcomes are the psychological state ofthe patient, personal and cultural issues associated with the disease, its effects on social relationships, itscognitive effects as well as other intangible effects. Each of these outcomes needs to be captured in themeasurement process in order to observe the true changes in the multidimensional measure of well-being.In a comprehensive review covering 30 years, Hansluwka (1985) assessed that the challenge remained todevelop appropriate measures that are comparable, yet reflect the multidimensional nature of health.

Table 1 features a list of 13 instruments resulting from waves of development of standardized instrumentsto measure various aspects of health as defined by WHO. The first set of instruments (1–5) wasdeveloped to measure the most severe health states among age groups and individuals living in long-termcare institutions. The second set (6–9) was developed with clinical and general populations in mind, andcombined self-assessment of descriptions of different dimensions of health and of performance indifferent activities and roles. This effort was spearheaded by WHO. The third wave (10–13) ofinstruments was developed and used in primary health settings. Disease-specific measures are more oftenused in clinical trials or with individuals receiving specialized treatment. Nearly all instruments areintended to provide data that would be useful for monitoring health status within clinical, research orevaluation settings.

The need for a unique quality of life measure

The need for cross-cultural comparison of the data generated through surveys compels researchers toimprovise on a multidimensional index for health. Two of the most popular indices are the quality-adjusted life year (QALY) and the disease-adjusted life year (DALY). QALY refers to a year of life in a

Page 106: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

100

health state adjusted by the utility (quality of life) associated with the health state (Drummond, Stoddart,and Torrance, 1987), whereas DALY represents the present value of future years of lifetime lost throughpremature mortality, and the present value of future lifetime adjusted for the average severity C… C of anymental or physical disability caused by a disease or injury (Fox-Rushby and Hanson, 2001). Once thesurvey results of a disease-based questionnaire are reduced to an index , monitoring the changes in QOLbecomes routine.

There are distinguishing features for DALY and QALY. While DALY is a disease-specific index, it is notbased on self-assessed utility associated with the relevant health state. Rather, it depends on experts’(mostly physicians) assessment of utility. On the other hand, QALY uses self-assessed utility associatedwith a health state, but it is not disease specific. Thus, none of these popular indices seem appropriate forBuruli ulcer. The index for Buruli ulcer-related quality of life (1) needs to be disease specific and (2)requires patients’ self-assessed utility for each health state of the disease. Therefore, Buruli ulcer requiresa unique QOL index that incorporates these two features. In particular, the challenge lies in the methodsfor eliciting utilities.

There are two ways of eliciting patient utilities: direct elicitation and indirect elicitation. By directelicitation, individuals are asked to compare their current health states relative to other health states, or todeath. In indirect elicitation, there are three steps to accomplish:

a. For population sample, measure utilities of different combinations of attributes;b. Ask individuals to classify health states by attributes;c. Apply utility weights from population-based samples to health-state classifications

The problem with the indirect elicitation is that this method is based on populations whose preferencesmay not map directly onto the Buruli ulcer populations This paper therefore recommends the use of thedirect elicitation method for deriving patient preferences. This paper proposes that a team of experts beassembled to agree on a generic QOL measure for Buruli ulcer, and the core areas of inquiry that wouldform the basis for survey instruments that would be designed, tested and modified if necessary foreventual application in all endemic communities.

STRENGTHENING BURULI ULCER SURVEILLANCE:EVALUATING THE EFFICACY OF EDUCATIONALMATERIALS

Dr Clare Dykewicz

Significant under-reporting and late detection of Buruli ulcer persists in countries endemic for the disease.In 2003, the Ministry of Health of Ghana (MOH) noted that 72% of reported Buruli ulcer cases had late(ulcerative) disease. In 2004, the MOH identified under-recognition of early cases of the disease as asignificant barrier to achieving good surveillance, and requested assistance from the United States Centersfor Disease Control and Prevention (CDC) assistance in improving Buruli ulcer education as a means ofstrengthening Buruli ulcer surveillance.

A preliminary investigation conducted in January 2005 revealed that distribution of the WHO comic bookon Buruli ulcer to schoolchildren is the main means of educating the general population in Ghana aboutthe disease. However, the educational efficacy of the comic book is unknown. CDC proposes to assess thecurrent knowledge, attitudes, practices and beliefs about Buruli ulcer in endemic villages in Ghana inwhich the comic book has been distributed.

We plan to use the results of this assessment to develop an improved educational programme that isadapted for an audience of Ghanaian schoolchildren, implement it in an intervention area and assess itsefficacy in improving knowledge, attitude, practices and beliefs regarding Buruli ulcer.

Once an educational programme adapted to Ghana is shown to be effective by field testing, it can beimplemented throughout Ghana. We hypothesize that widespread use of an efficacious educationalprogramme will result in a decreasing percentage of reported Buruli cases that are in the late (ulcerative)form, leading to decreased morbidity and disability from the disease.

STANDARDIZED RECORDING AND REPORTING SYSTEMUSING THE BU 02 FORM AND HEALTHMAPPER

Dr Ghislain Sopoh

The development of a surveillance system requires a reliable strategy for data collection, compilation ofcollected data and data analysis in order that information useful for decision-making can then be extracted.

The forms used for data collection must be simple and easy for staff to use. To this end, WHO hasdesigned a form (BU 02) intended to be used to record data at both health facility and community level.

The data collected on the BU 02 form can be compiled at the nearest specialist treatment centre, where aninitial analysis of the data can also be carried out. Using data from the BU 02 form, it is possible tocalculate most indicators necessary for the epidemiological surveillance of Buruli ulcer.

For two years, the form has been used in Benin to record and report over 1500 cases. Registers withdetachable sheets were created for this purpose. These registers are made available to Buruli ulcerdetection and treatment centres, as well as to case detection teams. A report is sent to the relevantinstitution each quarter by simply detaching the top two sheets. The stub is kept at the data collectionpoint. The data is centralized at the CDTUB (Buruli ulcer detection and treatment centre) in Allada,which regularly calculates the indicators and is responsible for mapping the data. Thus this databasemakes information on the following indicators available to every level of the health pyramid at any giventime:

Number of recorded cases over a given period

Proportion of different forms of the disease

Proportion of laboratory-confirmed cases

Ratio of number of nodules to number of ulcers

Proportion of disabilities

Proportion of post-treatment sequelae

Relapse rate

CExamples are given on the tables attached as annexes. C

Equally, case distribution over the period is mapped so that the level of endemicity in each district can betracked (see examples of maps).

Time permitting, we will describe the principles for recording and analysing data (tables, graphs andmaps) using the electronic version of the BU 02 form.

MYCOBACTERIUM ULCERANS TOXIC MACROLIDE,MYCOLACTONE MODULATES THE HOST IMMUNERESPONSE AND CELLULAR LOCATION OF M. ULCERANS INVITRO AND IN VIVO.

Sarojini Adusumilli,1 Armand Mve-Obiang,2 Tim Sparer,1 Wayne Meyers,3 John Hayman,4 P.L.C. Small1

Mycobacterium ulcerans produces an extracellular infection (Buruli ulcer) characterized byimmunosuppression. This unusual mycobacterial pathology is attributed to an immunomodulatorymacrolide toxin, mycolactone. M. marinum, a related mycobacterial pathogen, which causes anintracellular granulomatous disease. We have explored the role of mycolactone in the virulence ofM. ulcerans using genetically defined mycolactone-negative mutants. Two types of mycolactone-negativemutants were used in these studies: 1) strains that had a deleted portion of the mycolactone gene cluster,and 2) mutants containing transposon insertions in mycolactone biosynthesis genes.

Using a guinea-pig model, we show that WT M. ulcerans produces an extracellular infection, whereasmycolactone-negative mutants produce an intracellular inflammatory infection similar to that of M.marinum. Chemical complementation of both classes of M. ulcerans mutants with mycolactone restoresWT M. ulcerans pathology, showing that the phenotypes associated with mutant strains are caused solelyby the loss of mycolactone genes. We have also studied mycolactone cellular effects in vitro using bothmurine macrophages and human neutrophils. In vitro mycolactone mutants are phagocytosed moreefficiently than WT M. ulcerans. However, mycolactone-negative mutants are capable of growth withinmacrophages in vitro and are able to persist for in vivo for 6 weeks without causing disease. Mycolactoneis toxic for human neutrophils, as it is for macrophages. Neither WT M. ulcerans nor mycolactonenegative strains are strong neutrophil attractants.

Studies also demonstrate host specificity for M. ulcerans disease. Whereas M. ulcerans produces anextracellular minimally inflammatory infection in guinea-pigs, M. marinum produces an intracellularinflammatory infection. In mice, both M. marinum and M. ulcerans produce intracellular infections,suggesting that there are crucial differences in the recognition of M. ulcerans and mycolactone by miceand guinea-pigs.

Finally, we have explored the cellular effects of mycolactone using a wide range of concentrations. Thesestudies show that mycolactone causes both apoptosis and necrosis. However, necrosis is only associatedwith concentrations of mycolactone above 1 ug.

HIGH RATES OF APOPTOSIS IN MYCOBACTERIUMULCERANS CULTURE POSITIVE LESIONS OF BURULIULCER

Dr Douglas Walsh

Background

Buruli ulcer, a disease caused by Mycobacterium ulcerans, causes ulcerative skin disease likely generatedby a toxin that mediates apoptosis.

Methods

We analysed paraffin-embedded sections of surgically excised Buruli ulcer lesions (2 ulcers and 1oedematous plaque) and adjacent non-lesional skin samples (n = 9) for apoptosis by an indirectimmunofluorescent terminal deoxynucleotide-transferase mediated dUTP-digoxigenin nick-end labelling(TUNEL) assay. All samples were stained for acid-fast bacilli (AFB) and cultured for mycobacteria, andmost were analysed with an M. ulcerans-specific diagnostic polymerase chain reaction (PCR).

Results

TUNEL(+) bodies were numerous in both ulcers and the plaque, and sparse or absent in adjacent non-lesional skin. AFB tissue stains and cultures for M. ulcerans were positive only in the 3 lesions. The PCRfor M. ulcerans was positive in all 3 lesions and in 4 of 6 non-lesional tissue samples; 3 contained sparseTUNEL(+) bodies.

Interpretation

An abundance of TUNEL(+) bodies in the 3 AFB stain (+), culture (+) and PCR (+) Buruli ulcer lesionalsamples, but not in nearby AFB stain (–), culture (–) and PCR (+) non-lesional skin samples, strengthenthe evidence that apoptosis is an important tissue destruction mechanism closely associated with viableM. ulcerans.

LOCAL AND SYSTEMIC IMMUNE RESPONSE TOM. ULCERANS INFECTION AND CORRELATIONS WITHHISTOPATHOLOGY

Phillips R, Horsfield C, Mangan J, Laing K, Butcher P, Nyamekye B, Awuah P, Nyarko KM, Osei-Sarpong F, Etuaful S, Kolk A, Lucas S, Wansbrough-Jones M

Introduction

In the early stages of Buruli ulcer, nodules show extensive subcutaneous necrosis and abundant clumps ofextracellular acid fast bacilli (AFB) but, in long-standing lesions there is a mixture of acute and chronicinflammation with granulomas and the number of AFB is greatly reduced, suggesting cell mediatedimmunity plays a role in healing. In one study, 30% of lesions healed spontaneously, suggesting anadequate immune response can eliminate infection. It has been reported that Buruli ulcer patients areunable to mount an adequate TH1 response, so we have investigated the cytokine response of wholeblood from patients infected with M. ulcerans (Mu) with disease at different stages and used real-timepolymerase chain reaction (PCR) to quantify tissue cytokines. Tissue responses were correlated withsemi-quantitative histopathology.

Methods

Patients with Mu disease were recruited from 3 districts in Ghana. Using a whole-blood assay IFN-andIL-10 responses to Mu sonicate, Mu culture filtrate (Ag423, Ag425) and M. tuberculosis sonicate weremeasured in 44 subjects with active Mu disease (16 nodules, 28 ulcers), 29 healed Buruli ulcer patients,27 household contacts, 30 non-endemic area controls, 30 untreated tuberculosis patients and 29tuberculosis patients (HIV negative) during treatment. Expression of cytokine mRNAs was quantified byreal-time PCR in tissue from 46 Buruli ulcer patients and 11 with other conditions.

Results

Significant interferon (IFN) production in response to whole-blood stimulation with Mu sonicate wasdetected in patients with ulcers (632.5 ± 125.7 pg/ml; mean +/– SE), which was higher than that inpatients with nodules (243.2 ± 79.11; p = 0.0108 Mann Whitney) but similar to subjects with healedBuruli ulcer (522.7 ± 97; p = 0.1872). The mean IFNresponse in household contacts of Buruli ulcerpatients was 133.9 ± 31, which was not significantly different from that in 30 healthy control subjectsfrom a non-endemic area (78.3 ± 9). Results in 30 patients with untreated, smear-positive pulmonarytuberculosis and 29 tuberculosis patients on treatment for more than 2 weeks were 110.2 ± 22 and226.7 ± 76 respectively, showing that Buruli ulcer patients responded better to Mu antigens thantuberculosis patients. Similar results were found using M. tuberculosis sonicate as antigen but treatedtuberculosis patients had higher responses. In contrast, IL-10 results were higher in patients with activeMu disease (831 ± 123 pg/ml) than in those with healed lesions (396 ± 45 pg/ml), but the pattern ofresponse was similar to that seen in tuberculosis. Two culture filtrate antigens of Mu gave similar resultsand neither appeared to be highly specific.

In tissue samples, there was higher expression of Th1 cytokine mRNAs including IFNcompared withTh2 cytokines, and expression levels were similar between nodules and ulcers. There was significantlyhigher expression of IL-8 and other pro-inflammatory cytokines in 46 tissue samples with neutrophiliathan in 12 without acute inflammation; patients administered antibiotics appeared to mount a profoundIL-8 response. A total of 10 tissue samples containing granulomas showed high mRNA expression forIFN-, IL-1, IL-12p35, IL-12p40, IL-15 and TNF-compared with 19 tissues without granulomas.

Conclusions

In the early stages of M. ulcerans disease there was a mixed TH1 and TH2 cytokine response, but theTH1 response emerged as the dominant type. Acute inflammation with high IL-8 expression followedantibiotic therapy, suggesting that it heralded the onset of healing and granuloma formation when therewas high IFN, IL-1, IL-12p35, IL-12p40, IL-15 and TNF-expression.

Development of Buruli ulcer after exposure to M. ulcerans might be determined by genetic host factors.To test this hypothesis, we took finger-prick blood dried on filter papers (FTA) from consenting studysubjects in Ghana. We enrolled 182 Buruli ulcer patients (102 with positive laboratory confirmation) and193 matched healthy controls, and studied three polymorphisms in the NRAMP1 gene: 3’ UTR, D543Nand INT4. All three polymorphisms tested were in Hardy-Weinberg equilibrium. D543N wassignificantly associated with Buruli ulcer: the odds ratio of the GA genotype versus the GG genotype was2.50 (95% CI: 1.26–4.96). Combination of G+-GA–ins/ins had an odds ratio 2.56 (95% CI:1.14–5.71) inBuruli ulcer patients.

In conclusion, a genetic polymorphism in the NRAMP1 gene plays a role in susceptibility to developingBuruli ulcer, with an estimated attributable risk of 12.8%. Other genetic and environmental risk factorsshould, however, also be considered.

NERVE DAMAGE BY BACTERIA CAUSING BURULI ULCER –ULTRASTRUCTURE OF MOUSE INOCULATED WITHMYCOBACTERIUM ULCERANS

Buruli ulcer is an intractable skin disease caused by Mycobacterium ulcerans. It is observed in tropicalarea such as Africa and Australia. Large, necrotizing, relatively painless, deep skin ulcers are formedmainly in the extremities. Because of chronic course and occasional complication of severe deformities,socioeconomic handicap is a great problem.

A recent study demonstrated that phenolic glycolipid-I (PGL-I), a M. leprae-specific membranous antigenresponsible for Schwann cell invasion, is present in Buruli ulcer. Thus, we hypothesized that not only M.leprae but also M. ulcerans may invade peripheral nerves.

Materials and methods

Bacterial suspension of M. ulcerans colony 97-107 cultured at 32 °C in 7H9 culture medium(CFU = 1.3X106/ml, 25ml) was inoculated into the bilateral footpads of female BALB/c mice. Localswelling and redness were observed at day 33 after the inoculation, and sequential histopathologicalexamination was then performed.

Perfusion fixation by 10% formalin was done, and hind limbs were histopathologically examined by HE,acid-fast staining and immunohistochemistry using anti-PGL-I antibody. In selected cases, perfusionfixation by 2% glutaraldehyde was also done, and hind limbs embedded in Epon, cut into 1mm wereexamined. Where nerve damage was observed, electron microscopic examination was performed.

Results

Day 33 after the inoculation of M. ulcerans. Dermal erosion and extensive oedema of subcutaneous tissuewere associated with infiltration of small numbers of neutrophils and monocyte. Granuloma formationwas absent. Small clusters of long acid-fast bacilli (AFB) were noted, mainly in the stroma and in thecytoplasm of monocytes (Figure 1). Peripheral nerves were well preserved even in the oedematous lesion.

Day 55 after the inoculation of M. ulcerans. Remarkable deep skin ulcer and extensive subcutaneousoedema were observed. Large numbers of acid-fast bacilli formed clusters in the oedematous stroma.Many nerve bundles were well preserved, but some showed vacuolar change of Schwann cells (Figure 2),and others were invaded by numerous AFB with massive nerve damage. Ultrastructurally, the AFB weremainly in the endoneurium, and Schwann cells were spare (Figure 3). PGL-I immunohistochemistry wasnegative.

Discussion

Among the mycobacterial species, only M. leprae is known to show neurotropism and causes nervedamage. In the previous studies, mild degenerative change with thickening of Schwann cell basal laminaand vacuolar change of axons were reported {Mwanatambwe, 2000}, but direct nerve invasion by theAFB has not been found. Our study first demonstrated that nerve bundles are damaged by numerousM. ulcerans. This finding raises a new possibility of the pathogenesis of the “painlessness” of Buruli ulcer.

VACCINE OPTIMALIZATION BY EXPERIMENTAL MOUSEMODEL FOR MYCOBACTERIUM ULCERANS FOOTPADSINFECTION

Dr Audrey Tanghe

As of now, there is no specific vaccine against Mycobacterium ulcerans, but evidence in the literaturehas suggested a cross-reactive protective role of the M. bovis BCG vaccine used against tuberculosis. Toachieve an early diagnosis, to find the mechanism of transmission and to focus on a vaccine are prioritiesto control the disease. Many studies have shown that DNA vaccination is a good way for a newvaccination protocol. Previous studies have shown that prior vaccination with plasmidique DNA vaccine,encoding either antigen 85A (Ag85A-DNA) or antigen 85B (Ag85B-DNA), offers good protection inC57BL/6 (B6) mice infected with M. tuberculosis H37Rv. This antigen 85 complex is a 30–32 kDafamily of three proteins (Ag85A, Ag 85B and Ag85C), which all possess a mycolyl transferase enzymeactivity, important for the biogenesis of the mycobacterial envelop. In view of these results, and becauselittle is known about the antigens implicated in M. ulcerans protection, our laboratory has focused itswork on antigen 85A.

In 2001, we identified and sequenced the Ag 85A component from M. ulcerans strain 5150. A cross-reactive protection was demonstrated. Indeed, prior vaccination with either BCG or plasmid Ag85A-DNAfrom BCG was able to reduce significantly the bacterial load in the footpads of mice infected withM. ulcerans, strain 5150, B6. Unfortunately, the protection observed after vaccination with Ag85A-DNAfrom BCG was below the one given by BCG vaccine alone. So we decided to analyse a) the protectiveefficacy of a DNA vaccine encoding the species-specific Ag85A protein from M. ulcerans, b) theprime/boost strategy combining DNA followed by the protein injection and c) double BCG vaccine. Inspite of a good sequence identity between the two Ag85A homologs in M. bovis BCG and in M. ulcerans,results suggest that the vaccination with the DNA encoding the specific M. ulcerans Ag 85A has the sameprotective effect as the Ag85A-DNA from BCG.

After cloning and purification of the specific protein 85A from M. ulcerans,, we used a vaccinationprotocol combining DNA and protein boost, in B6 mice. Immunological response studies have shownproduction of Th1 cytokines (IL-2 and IFN-) increased by the boost with the protein compared with theDNAp vaccine alone. An infection with 105 AFB of 04-855 M. ulcerans strain was done, 12 weeks afterthe last immunization, in the footpads of the mice. The protective effect was measured by the delay forthe appearance of footpad swelling and with an “oditest” measure apparatus. Unfortunately, the boostwith the protein does not give better protection in comparison with the BCG vaccine. In humans, BCGseems to give a short-term protection against the development of Buruli ulcer and a more sustainedimmunoprophylactic effect for the most severe form of the disease, the osteomyelitis.

A booster vaccination with BCG can offer additional protection against leprosy than with a single BCGinjection. Therefore, we decided to investigate protection in mice injected twice intravenously with M.bovis BCG. The experiments were carried out on B6, BalbC and BalbB10 mice. Infection with 105 AFBof M. ulcerans strain 04-855 took place 10.5 and 14 months after the first injection of BCG. According toour preliminary first data, it is clear that a double or single injection with BCG does not give completeprotection and that double BCG injection does not increase the protective effect of the single injection.Nevertheless, a new, similar experiment will be done on young mice with a reduced time between BCGinjections and M. ulcerans infection in mouse footpads. The study of the sensibility of different haplotypemouse strains to M. ulcerans strain 04-855 footpad infection is in progress and will allow a betterunderstanding of the immunological implication of H-2 molecules and to define a more susceptiblemouse strain for further development of vaccine candidates against M. ulcerans.

CONSTRUCTION OF MYCOLACTONE-NEGATIVE MUTANTSOF MYCOBACTERIUM ULCERANS MAY CONTRIBUTE TOTHE DEVELOPMENT OF VACCINE CANDIDATES AGAINSTBURULI ULCER

Armand Mve-Obiang,1 Brian Ranger,2 Kris Huygen,1 Pamela Small2

Mycobacterium ulcerans causing Buruli ulcer is a mycobacterium whose pathogenicity is related to theproduction of a polyketide toxin called mycolactone (ML). The genes involved in the synthesis of thistoxin are localized on a 174 kb plasmid (1). So far, there is no effective vaccine against Buruli ulcer, andlittle is known on the immune mechanisms involved in protection (2). As for all other mycobacterialinfections, generation of potent CD4+ and CD8+ mediated responses against protein antigens is thoughtto be essential, although it is not excluded that neutralization of the toxin by antibodies may also beimportant. Using transposon mutagenesis, we have produced a number of ML-negative mutants,inactivated in genes involved in the toxin biosynthesis. Southern-blot and sequencing were performed toprove that each mutant was the result of one transposon insertion. Mass spectrometry and thin-layerchromatography allowed physical demonstration of the loss of ML production, and in vitro cytotoxicitytests on L929 cells were carried out and confirmed the absence of ML activity. Intradermal injection inguinea-pig skin of the ML-negative mutants did not cause the typical Buruli ulcer necrosis, and, incontrast to M- producing, wild type M. ulcerans (which is extracellular in this model), the ML-negativemutants were found inside the host macrophages. Experiments are in progress to evaluate in mousefootpad model (3) the immunogenicity and the protective efficacy of ML-negative mutants and DNAvaccines encoding for a number of genes involved in ML biosynthesis.

NEW LABORATORY TOOLS FOR STUDYINGMYCOBACTERIUM ULCERANS INFECTION

Gerd Pluschke, Jean-Pierre Dangy, Diana Diaz, Simona Rondini, Dorothy Yeboah-Manu

Swiss Tropical Institute, Basel, Switzerland*

Our goal is to develop new immunological and molecular biological tools that facilitate research on theimmunology, pathogenesis and transmission of Buruli ulcer.

A quantitative real-time PCR method for the detection of Mycobacterium ulcerans DNA (Rondini et al.,2003) has been used to analyse the development of satellite infection foci in Buruli ulcer lesions.

Results obtained with a microarray-based system for the analysis of genomic DNA have shown thatinsertional/deletional diversity is common in M. ulcerans. This may facilitate development of afingerprinting method for micro-epidemiological field studies.

Primary isolation of M. ulcerans from surgical specimens has been optimized (Yeboah-Manu et al., 2004).Under optimal conditions, cultivation turned out to be as sensitive as other laboratory methods forreconfirmation of clinical diagnosis.

Monoclonal antibodies specific for immunodominant protein antigens, capsular components and themycolactone toxin of M. ulcerans are being generated and characterized. One of the immunodominantproteins identified may be a suitable target structure for an immunological test detecting infection and/orexposure to M. ulcerans.

SENSITIVITY OF PCR FOR IS2404 INSERTION SEQUENCE OFMYCOBACTERIUM ULCERANS IN DIAGNOSIS OF BURULIULCER FROM PUNCH BIOPSIES

Phillips R, Horsfield C, Kuijper S, Lartey A, Tetteh I, Etuaful S, Nyamekye B, Awuah P, Nyarko K.M,Osei-Sarpong F, Lucas S, Kolk A.H.J, Wansbrough-Jones M.

Punch biopsies from M. ulcerans disease lesions have been used to compare the sensitivity and specificityof direct smear, culture, polymerase chain reaction (PCR) and histopathology in making the diagnosis ofMycobacterium ulcerans disease in a field setting. PCR for the insertion element IS2404 was modified toinclude uracil-N-glycosylase and dUTP instead of dTTP to reduce the risk of cross-contamination. Thegold standard for confirmation of clinically diagnosed Buruli ulcer was a definite histological diagnosis,or positive culture for M. ulcerans, or a smear positive for acid-fast bacilli (AFB) together with a possiblehistological diagnosis. For 70 clinically diagnosed cases of M. ulcerans disease, the modified PCR was98–100% sensitive and gave a rapid result. The sensitivities of microscopy, culture and histology were43%, 50% and 83% respectively. A 4mm punch biopsy was preferred to a 6 mm punch biopsy since itwas less likely to bleed and to need stitching. Given adequate technical expertise and controls, the PCRwas viable in this teaching hospital setting in Ghana and, in routine practice, we would recommend Ziehl-Neelson staining of biopsies to detect AFB, followed by PCR in AFB-negative cases only, in order tominimize costs. Histology and culture remain important as quality control tests, particularly in studies oftreatment efficacy.

GENOTYPING MYCOBACTERIUM ULCERANS,MYCOBACTERIUM MARINUM AND RELATED SPECIES USINGMYCOBACTERIAL INTERSPERSED REPETITIVE UNITS

A novel category of variable tandem repeats (VNTR) called mycobacterial interspersed repetitive units(MIRUs) has been identified for Mycobacterium ulcerans (n = 51) and M. marinum (n = 55) (1).

A total of 15 possible MIRU loci were localized in the genome of M. marinum and were used forgenotyping M. ulcerans, M. marinum, M. liflandii (n = 4), 1 M. shottsii (ATCC 700981), and 1 M.marinum-like organism considered a possible “missing link” between M. marinum and M. ulcerans.Some 6 MIRU loci were found polymorphic, and locus-specific PCR at these loci differentiated 9M. ulcerans genotypes, 13 M. marinum genotypes and unique genotypes for each of the following species:M. shottsii, “M. liflandii” and the “missing link”. Both earlier and recent isolates of M. ulcerans from 6African countries as well as old and recent isolates belong to the same genotype, emphasizing the greatspatio-temporal homogeneity among African isolates. Unlike M. ulcerans, the genotypes of the 13M. marinum isolates did not clearly predict their geographical origin. However, using MIRU-VNTRtyping, all M. ulcerans and M. marinum isolates of American origin and the original American M.liflandii and M. shottsii were closely related, suggesting a common American ancestor for thesepathogenic species on the American continents.

MIRU-VNTR typing can be directly applied on Ziehl-Neelsen positive clinical samples. For example, bythis method we differentiated an isolate from Sudan from the other African M. ulcerans. Remarkably, inPapua New Guinea, a relatively small geographical area compared with Africa, three genotypes werefound. Initial findings suggest that one of these genotypes resembles M. ulcerans from Cameroon;however, this requires confirmation.

MIRU typing is a rapid and effective method for determining the origin of isolates and rapididentification of genotypes of M. ulcerans, M. marinum and related species. Moreover, MIRU typingshould have significant potential for the discrimination of relapse from reinfection in M. ulcerans disease.

Using genomic and post-genomic techniques, an exhaustive proteome study is under way in order tostudy the relationship between the bacillus and its host, the water bug. The study will make it possible toidentify and compare bacterial proteins produced in vitro and in vivo (by the water bug).

Apart from answering fundamental questions, the information gathered through this research into theproteome will subsequently be used to develop diagnostic, vaccine and preventive tools.

IDENTIFICATION OF MYCOBACTERIUM ULCERANS IN THEENVIRONMENT BY PCR: LIMITATIONS OF IS2404 AS PROOFFOR M. ULCERANS IN THE ENVIRONMENT, ANDDEVELOPMENT OF A MYCOLACTONE-SPECIFIC PROBE

Heather Williamson, Brian Ranger, Tim Stinear, and P.L.C. Small

Several lines of evidence suggest that reliance on IS2404 as a probe for Mycobacterium ulcerans inAfrica may not be definitive: 1) IS2404 has been detected in several M. marinum isolates as well as in thefrog pathogen, M. liflandii; 2) PCR positivity does not correlate with the ability to culture organisms(personal communication, Francoise Portales, Laurent Marsollier). Although this could be becauseorganisms are in a non-culturable state in the environment, Laurent Marsollier has shown that M.ulcercans can be readily cultured from laboratory-infected insects; 3) AFB (acid-fast bacilli) staining ofPCR-positive environmental samples reveals few or no AFBs; 4) the yield of IS2404-positive samples inthe environment is extremely high and spans many species, suggesting lack of specificity; 5) bandsproduced from environmental samples are faint, leading to the suggestion that few organisms are present;and yet in M.ulcerans hundreds of copies of the IS element are found; 6) we have recently obtainedIS2404-PCR positive environmental samples from Michigan and Tennessee, suggesting that this insertionsequence may be widely distributed in nature.

In preliminary studies with environmental isolates collected in Ghana, we obtained a high proportion ofIS2404 samples – sometimes as high as 75%. Following consultation with investigators from the UnitedStates Centers for Disease Control and Prevention (CDC), we began to include insects collected locally(Michigan and Tennessee) in these studies as negative controls and found several confirmed positives.Because we suspected that many of these samples were not truly positive for M. ulcerans, we consideredwhether the use of a mycolactone probe might be more specific. The polyketide synthases for themycolactone core are encoded by mlsA. Within mlsA lies the ER region, which is present in three copies.Although the copy number of the plasmid has not been determined, it is likely to be present in 1–3 copiesmeaning that each M. ulcerans bacteria will possess 3–9 copies of the ER. In a true environmentalreservoir where bacterial replication occurs, it would be reasonable to expect to find at least 10 organismspresent, which would translate into 30–90 copies of the ER. This should be detectable by PCR.

When we used a DNA probe for the ER (5’- gagatcggtcccgacgtctac-3’ and 5’-ggcttgactcatgtcacgtaagg-3’)against a group of environmental samples, our positivity rate fell to 2%. Although this probe is not likelyto be 100% specific for M. ulcerans because other environmental bacteria may contain the mycolactoneplasmid, a probe to the ER is likely to be more specific for M. ulcerans than IS2404. It is of some interestthat in Australia, the rate of IS2404-positive strains is much lower than that in Africa, suggesting thatIS2404 may have greater M. ulcerans specificity in Australia.

Although it is likely that some of the IS2404-positive samples from the environment really do contain M.ulcerans, results from our studies suggest that the presence of IS2404 in environmental samples should nolonger be considered presumptive evidence for the presence of M. ulcerans without further validation.

BURULI ULCER CONTROL INTEGRATION MODELFOR PUBLIC HEALTH ESTABLISHMENTS: PILOT PROJECTTO IMPROVE AWARENESS OF AND TREAT BURULI ULCERPATIENTS IN TAABO, CÔTE D’IVOIRE

Dr Julien Ake Ake, Aubin Koffi Yao

The problem

In Côte d'Ivoire, a national survey conducted in 1997 helped reveal an incidence of some 15 000 cases ofBuruli ulcer, spread through 56 of the country’s 58 districts. Each year, about 2500 new cases arereported.

In the country as a whole, there are approximately 1700 health establishments in operation and awidespread network of community health workers, all coordinated in some 80 health districts. However,only six health establishments provide proper treatment of patients.

It will be noted that such cases very often consist of ulcerations or complicated cases, with lowerreporting of pre-ulcerative forms. The epidemiological picture of the disease nationwide is also poorlyknown.

If the condition is to be more effectively combated and its harmful consequences alleviated, access to caremust be improved and awareness and monitoring activities extended. To do so, the Buruli ulcer controlprogramme must be centralized by incorporating it in the general health effort.

After developing the relevant intervention tools, MAP International for west and central Africa and ALM,in collaboration with the National Mycobacterial Ulcers Control Programme (PNUM), decided toundertake a pilot project for integrating the Buruli ulcer control programme with the general publichealth system.

Project title: Pilot project for promoting awareness of and treating Buruli ulcer patients in Taabo

Project area: Taabo Sub-prefecture, Tiassalé Health District.

Project duration: 30 months: from July 2004 to December 2006.

Overall objective: To test a model for integrating the Buruli ulcer control programme into the publichealth structures of Côte d’Ivoire.

Specific objectives

To identify, train and equip a local coordinator with the tools for supervising activities.

To strengthen the ability of 20 nurses, 25 community health workers, 2 surgeons and 2physiotherapy assistants to improve knowledge, conduct early tracing, prevent disability andcarry out epidemiological surveillance.

Page 125: ABSTRACTS OF THE ANNUAL MEETING ON BURULI ...Every March, WHO organizes a meeting in Geneva that brings together representatives from the ministries of health of affected countries,

119

To equip 4 rural health centres, 1 rural dispensary and 1 private infirmary with nodulectomy kits,public awareness tools and reporting registers.

To provide the Taabo General Hospital (reference hospital) with excision-grafting andnodulectomy kits, public awareness tools and a reporting register.

To provide pharmaceutical drugs and medical consumables to all patient treatment facilities, withthe support of the PNUM.

To strengthen the abilities of 10 Christian volunteers to provide schooling and psycho-spiritualsupport to hospitalized patients.

To establish a partnership with a specialized agency for providing training, physicalrehabilitation and socioeconomic reintegration for cured patients who suffer incapacitatingsequelae.

Interest arising from the project

It reduces the cost of treating patients and providing support for their families and the healthsystem:

– less uprooting from patients’ ordinary places of residence

– fewer ulcerated forms and complications

– shorter hospital stays

– better use made of existing skills and capacities: local health facilities and equipment, healthprofessionals and community health workers.

Treatment of patients in their home settings, thereby avoiding homesickness and other problemsrelating to being cut off from families.

Lasting assistance

– incorporation of the project in the health district

– availability of local skills and capacities to ensure that assistance will be longer lasting

– involvement of the beneficiary community

Better mapping of the disease

Treatment of Buruli ulcer becomes a day-to-day activity and part of the core activities of healthservices.

Preliminary results

Statistics relating to screening activities and treatment of Buruli ulcer cases from November 2004 toJanuary 2005.
