Features Supportive of CD vs. UC
• involvement of the small bowel
• sparing of the rectum
• absence of gross bleeding
• presence of bothersome perianal disease
• focality of gross and microscopic lesions
• presence of granulomas
• occurrence of fistulae

• Diarrhea, typically bloody and with mucus

Clinical Presentation of Ulcerative Colitis
• Abdominal pain and tenderness
• Loss of appetite and weight
• Fever
• Fatigue
• Urgency for bowel movement• Urgency for bowel movement
• Urinary symptoms
• Children: growth and developmental failure

• Overall prevalence of CRC in any UC patient is 3.7%• Pancolitis > more limited forms
B12
• Crohn’s disease patients with ileali l t il l ti iinvolvement or ileal resection require lifelong parenteral B12 (usually monthly)
• Levels not reliable to determine need either early on or during parenteral therapy
• Very small minority of CD pts have had• Very small minority of CD pts have had gastric resections– They also require B12
13
Folic Acid(Also Called Folate)• Anemia can develop with low body amounts
• All women who could possibly get pregnantAll women who could possibly get pregnant should take 400 micrograms of folic acid every day in a vitamin or in foods that have been enriched with it
• Helps prevent neural tube defects (ex., spinabifida)b da)
• Sulfasalazine patients often recommended folate1 mg day
• Methotrexate patients usually recommended to take folic acid at a dose of 1 mg/day
General Goals of Therapy for IBD
• Inducing remission
• Maintaining remission
• Restoring and maintaining nutrition
• Maintaining patient’s quality of life
• Surgical intervention (selection of optimal time for surgery)
14
What Detemines Choice of Therapy?Some important factors …
• CD vs. UC vs. indeterminate• Disease locationDisease location• Disease severity• Disease behavior
– perforating, strictures• Age of patient• Other medical conditions• Patient preferences & abilities• Availability of treatments
– usually refers to surgery• Reproductive issues
Categories of Medications
• Sulfasalazine
• 5-aminosalicylates
• Antibiotics
• Corticosteroids (i.e., steroids)
• Other immunomodulators
• Biologics
15
Sulfasalazine
• 1 of the older medications
• Most useful for colon disease
• Several wks to full effect
• Allergic reactions; sulfa
• High doses headache
• Folic acid supplements needed
• Less expensive
5- aminosalicylates(5-ASA or mesalamine)
• Multiple forms
• Idea get medicine to where the disease is
• Oral and rectal
• 2 different pill typesA l® & P t ®– Asacol® & Pentasa®
• 2 different rectal medications– Enema & suppositories
16
Common side effects of 5-ASA
• Headache
Abd i
• Dizziness
U i di l ti• Abd pain
• N/V
• Weakness or fatigue
• Belching
• Diarrhea
• Urine discoloration
• Indigestion
Rare Side Effects of 5-ASA
• Bone marrow suppression
• Pericarditis
• Pancreatitis
• Severe allergic symtpoms
• Bloody diarrhea
17
Antibiotics
• Most commonly used®– Metronidazole (Flagyl®)
– Ciprofloxacin (Cipro®)

• Headache
• Dizziness
• PhotosensitivityPhotosensitivity
Rare Side Effectsof Ciprofloxacin
• ?? Joint damage in children• ?? Joint damage in children
• Tendonitis (inflammation of tendons)
• Hepatitis (liver irritation)
• Delirium
19
Steroids
• Used to get rapid control of disease
• Try to avoid for long-term
• Many side effects
• Works by suppressing the immune system
Other Immunomodulators (IM)
• Steroids are IM’s, too
• “Other” = non-steroid
• Usually second line
• 3-6 mos for effect
• More used in maintenance phase since onset slow
• Need for monitoring
20
Examples of Immunomodulators
• Azathioprine (Imuran®)
• 6-MP
• Methotrexate (MTX)
Common Side Effects of Azathioprine, 6-mercaptopurine and Methotrexate
• Bone marrow suppressionpp
• Hepatitis
• Pancreatitis (Azathioprine/6-MP)
• Slight increased risk of cancer long-term
• Methotrexate is a teratogen (category X)Methotrexate is a teratogen (category X)
21
Incidence of Azathioprine/6-MP Side Effects
• Allergic reactionsHigh fever and/or rash and arthritis– High fever and/or rash and arthritis
– 2.3 %
• Leukopenia due to bone marrow suppression– 1.4 %
• Pancreatitis1 4 %– 1.4 %
• Nausea– 1.4 %
Biologics for IBD
• Infliximab (Remicade®) - CD & UC
• Adalimumab (Humira®) - CD
• Certolizumab (Cimzia®) - CD
22
Infliximab, Adalimumab, Certolizumab
• Not usually first line, but more of such a l i C h ’ dirole in Crohn’s disease
• Infliximab now in CD & UC
• Expensive– $2,500/infusion or injection
Sid ff t• Side effects– infusion reactions, allergic problems,
opportunistic infections, sepsis
• Rapid onset of response

Infections with Anti-TNF Agents
• Opportunistic
• TB– Often disseminated or extra-pulmonary
• Pneumonia, histoplasmosis, coccidioidomycosis, listeriosis and pneumocystosispneumocystosis
• Bacterial infections including sepsis
• Should not be given to patients with a clinically important, active infection
Other Issues with TNF Inhibition
• HBV reactivation
• Contraindication in class III/IV CHF• Contraindication in class III/IV CHF
• Caution should be exercised when considering treatment of patients with a current or a past history of malignancy or other risk factors such as chronic obstructive pulmonary disease (COPD)
• Demyelinating disorders
• Consider discontinuation for significant CNS adverse reactions
• Hepatic reactions
• Lupus-like syndrome

Smoking and Ulcerative Colitis
• Cigarette smokingH t ti ff t d l t d f– Has protective effect on development and course of UC including extraintestinal and postsurgical events
– Nicotine therapy (gum, patch, enema) has mixed results
– Restart smoking in severe or refractory colitis?

• Ex-smokers more likely to develop extensive UC (second age peak > 40 years)
Ulcerative Colitis: Induction of Remission
• Mild/moderate disease– Aminosalicylate

• Treatment with mesalamine 4.8 g/day provided a statistically significant efficacy benefit over 2.4 y g yg/day in moderately active disease
• Both doses of mesalamine had similar safety profiles and both were well tolerated

Maintenance Therapies for Ulcerative Colitis
A i li l• Aminosalicylates
• Azathioprine/6-MP
• Infliximab (Remicade®)
35
Mortality and IBD
• IBD patients have an elevated mortality rate of 0.5% per year
• Extensive colitis and higher age (> 50 years) at diagnosis increase• Extensive colitis and higher age (> 50 years) at diagnosis increase the risk for a fatal outcome in UC
• Greatest hazard ratio (HR)
– UC – age group 40 to 59 years (HR 1.79)
– CD – age group 20 to 39 years (HR 3.82)
• IBD is associated with an overall small increase in mortality rate greatest in relative terms in younger subjects but in absolute terms in the elderly
Card T, et al. Gastroenterology. 2003;125:1583.Winther KV, et al. Gastroenterology. 2003;125:1576.
Final Points• There is no “one size fits all” to IBD therapy
– Therapy and decision making are tailored to the individual
• Algorithms are based upon available evidenceAlgorithms are based upon available evidence
– Evidence is in constant flux
• Success of algorithms depends upon optimization of each step of therapy and considerable judgment about each outcome
– Skillful application of medical therapy makes all the diff i tdifference in outcomes
• Need for better treatments since many only work about 50% of the time
• Success of newer medications have opened new doors for investigation
36
When to Suspect IBDInstead of IBS
• Red flags
If d fl IBD lik l• If no red flags, IBD unlikely
• Even if IBD present in some sort of subclinical state such that “red flags” are negative, hard to justify more than symptomatic rx
• … and that means GI specific care not needed itheither
• Kids are slightly different and need close attention and f/u to growth
*
37
Do Not Use the Panelsthat are Marketed
to Distinguish IBS from IBD (Prometheus)
• Useless in this setting
• Main utility is persons with indeterminate colitis who require surgery and may need a permanent ileostomy if disease is more C h ’ likCrohn’s-like
• I have not ordered one in years

Genetics Issues

IBD in Pregnancy: Summary
• Pregnancy outcomes best if patient in remission at time of conception
• CD may increase the risk of preterm birth and low birth weight, but UC may not
• No significant increase in risk of congenital abnormalities or maternal complications
• Women with IBD have a higher rate of cesarean sections
• Pregnancy may not increase the risk of relapse or significantly increase disease activityincrease disease activity
• Overall, outcomes for women with IBD are similar to those for general population
