The Name
Lupus (n.), Medieval Latin, late 14c • Apparently because it "devours" the affected part • Diseases that cause ulcerations of the skin • Earliest known medical use of “lupus”� appeared in a 10th
century biography of St. Martin (lived in 4th-century Gaul) The Bishop of Liege was healed at St. Martin's shrine in Tours:
“He was seriously afflicted and almost brought to the point of death by the disease called lupus. The location of the disease was not to be seen, nonetheless, a sor< of thin red line remained as a mark of the scar.”

History • “Lupus” associated with cancer or tuberculosis. • Diagnosis & treatment of LE in the domain of dermatologists until 1940s.
• SLE was recognized by its cutaneous findings • visceral manifestations were considered secondary to the cutaneous • In 1940s, accepted that SLE may occur without skin lesions
• The pioneers of rheumatology (the late 1920s) had neither technical nor therapeutic superiority over other internists. • 1948- rheumatoid factor and the LE cell (increase diagnosis of SLE) • 1949- cortisone therapy (patients can be helped, treatment required specialized
knowledge) • 1950- establishment of the Institute of Arthritis and Metabolic Diseases in the National
Institutes of Health.
• Shift in interest in LE from clinical description to immunologic research led to continued intensification of scientific interest (Index Medicus/Medline) • 8 columns in 1960, 21 in 1982, 25 in 1987, 31 in 1992, 47 in 1997, thousands
of references in 2006, 60,000 in 2014.

Diagnosis: no single test ANA
• Immunofluorescence is the standard approach • Staining patterns (i.e., homogeneous or diffuse, speckled, rim, nucleolar, or centromere)
• Depend on the location of the target antigen • Autoantibodies against different nuclear antigens
• Ideal screening test • Simple • High sensitivity (95% when human cultured cells used as substrate) • Negative test- <3% chance of SLE; not R/O (+) typical features
• Low specificity • Positive in Scleroderma, PM-DM, RA, autoimmune thyroiditis,
autoimmune hepatitis, infections, neoplasms, & many drugs • Healthy individuals:10-35% of individuals > 65 yrs ; low titer (<1:40)

The management of SLE should be based on shared decisions between the informed patient and her/his physician.
Treatment of SLE should aim at ensuring long-term survival, preventing organ damage, and optimising health-related QOL, by controlling disease activity and minimising comorbidities and drug toxicity.
The management of SLE requires an understanding of its many aspects and manifestations, which may have to be targeted in a multidisciplinary manner.
Patients with SLE need regular long-term monitoring and review and/or adjustment of therapy.
T2T in SLE: overarching principles
van Vollenhoven RF, et al. Ann Rheum Dis 2014;73:958–967. doi:10.1136/annrheumdis-2013-205139
![Page 20: The Problem of Lupus](https://reader033.vdocuments.us/reader033/viewer/2022052901/55655173d8b42a9b4c8b51ea/html5/thumbnails/20.jpg)
T2T in SLE: recommendations 1. The treatment target of SLE should be remission of systemic symptoms and organ manifestations or, where remission cannot be reached, the lowest possible disease activity, measured by a validated lupus activity index and/or by organ-specific markers. 2. Prevention of flares (especially severe flares) is a realistic target in SLE and should be a therapeutic goal. 3. It is not recommended that the treatment in clinically asymptomatic patients be escalated based solely on stable or persistent serological activity. 4. Since damage predicts subsequent damage and death, prevention of damage accrual should be a major therapeutic goal in SLE.
van Vollenhoven RF, et al. Ann Rheum Dis 2014;73:958–967. doi:10.1136/annrheumdis-2013-205139

T2T in SLE: recommendations 5. Factors negatively influencing health-related quality of life (HRQOL), such as fatigue, pain and depression should be addressed, in addition to control of disease activity and prevention of damage. 6. Early recognition and treatment of renal involvement in lupus patients is strongly recommended. 7. For lupus nephritis, following induction therapy, at least 3 years of immunosuppressive maintenance treatment is recommended to optimise outcomes. 8. Lupus maintenance treatment should aim for the lowest glucocorticoid dosage needed to control disease, and if possible,glucocorticoids should be withdrawn completely. van Vollenhoven RF, et al. Ann Rheum Dis 2014;73:958–967. doi:10.1136/annrheumdis-2013-205139

T2T in SLE: recommendations 9. Prevention and treatment of antiphospholipid syndrome (APS)-related morbidity should be a therapeutic goal in SLE; therapeutic recommendations do not differ from those in primary APS. 10. Irrespective of the use of other treatments, serious consideration should be given to the use of antimalarials. 11. Relevant therapies adjunctive to any immunomodulation should be considered to control comorbidity in SLE patients.
