  2. A link between specific genetic markers and the development of CD has not yet been identified
  3. Mutations in the NOD 2/CARD 15 gene result in failure of NF-κB activation, dysfunction in the innate immunity, and stimulation of a proinflammatory state
  4. Inflammation is thought to be secondary to a genetic predisposition to infection by the bacteria Saccharomyces cerevisiae

4. A 24-year-old woman presents to your clinic with new-onset abdominal pain and hematochezia that began 2 months ago. On examination, her abdomen is benign and she denies current bloody bowel movements. Colonoscopy shows distal colitis up to 40 cm and biopsies are consistent with UC. What is the most appropriate therapy for this patient?
  1. Prednisone 40 mg/d
  2. Mesalamine suppositories
  3. Mesalamine enemas in combination with an oral 5-aminosalicylate (5-ASA) drug
  4. Azathioprine in combination with prednisone
  5. No therapy is recommended until patient experiences further symptoms

5. Which of the following is an indication for the use of capsule endoscopy?

  1. A high clinical suspicion of inflammatory bowel disease (IBD) despite normal colonoscopy and small bowel follow-through
  2. Detection of distal lesions in patients with negative computed tomography enteroclysis
  3. Evaluation of suspected strictures in patients with CD
  4. Evaluation of fistula in CD
  5. Evaluation of extra-intestinal manifestations of IBD
