Adalimumab-psoriasis and Small Bowel Lesions

Adalimumab will be administered sub-cutaneously to all patients entering the study with a loading dose of 80 mg followed by 40 mg at week 1 and 40 mg every other week. Patients who did not have small bowel lesions detected will be in the study and receive adalimumab until week 12. Patients who had small bowel lesions detected will be in the study and receive adalimumab until week 24.

All patients will undergo capsule endoscopy (EndoCapsule EC type 1; Olympus) to treatment initiation (adalimumab) in order to detect the presence of small bowel lesions suggestive of Crohn's disease. Twenty-four (24) weeks after treatment with adalimumab was initiated, patients for whom small bowel lesions were detected will undergo a second capsule endoscopy to evaluate changes in bowel inflammation.
