  4. :09 Answer Now Audience Question 2 For a CD patient in whom AZA/6-MP treatment fails, how would you initiate anti-TNF therapy? • Discontinue AZA/6-MP, and then initiate anti-TNF therapy • Continue AZA/6-MP indefinitely in combination with anti-TNF therapy • Continue AZA/6-MP for a period of time while starting anti-TNF therapy, and then discontinue it Answer 3

  5. :09 Answer Now Audience Question 2 For a CD patient in whom AZA/6-MP treatment fails, how would you initiate anti-TNF therapy? • Discontinue AZA/6-MP, and then initiate anti-TNF therapy • Continue AZA/6-MP indefinitely in combination with anti-TNF therapy • Continue AZA/6-MP for a period of time while starting anti-TNF therapy, and then discontinue it Answer 3

  6. Case Study: TimPresentation to PCP • 18-year-old male high school student • Abdominal pain, 6-month duration • Weight loss, 10 pounds • 3 to 4 loose stools per day, some urgency • Doesn’t smoke cigarettes • Takes ibuprofen for prior basketball injury • 400 mg 3 or 4 times per day • No family history of CD PCP, primary care physician.

  7. TimExamination and Referral • Physical examination • Tenderness and fullness in right lower quadrant • Small perianal skin tags • Referred to gastroenterologist for diagnostic testing • MRE • Colonoscopy • Laboratory results • Hemoglobin 8.7 g/dL • WBC 10 х 109/L • Platelets 454,000 (normal range, 120,000-400,000) • CRP 25 mg/L (normal level, <4.0) CRP, C-reactive protein; MRE, magnetic resonance elastography; WBC, white blood cell.

  8. MRE Results • Long segment of terminal ileal inflammation • Some proximal colon thickening

  9. Colonoscopy Results • Colitis in ascending colon • Distorted ileocecal valve precluding intubation of the ileum

  10. TimDiagnosis • Moderate-to-severe CD of the ileum and colon with perianal involvement
