Behçet's disease-induced massive small intestinal bleeding successfully treated with adalimumab.

We herein report a case of Behçet's disease in a 27-year-old female who suffered from generalized skin rashes for one week. After hospitalization, massive bloody stools accompanying hypovolemic shock occurred. Emergency abdominal computed tomography-angiography failed to detect the bleeding source. Esophagogastroduodenoscopy also demonstrated no definite bleeding points. Ileocolonoscopy showed multiple large and deep ulcers with some blood coating and mild oozing in the terminal ileum. We initially performed epinephrine injection and hemoclips for her intestinal bleeding. However, massive bloody stools still continued. Thus, we prescribed a loading dose of 160 mg adalimumab followed by weekly 80 mg adalimumab subcutaneous injections to the patient. Following this treatment, her gastrointestinal bleeding gradually subsided and completely stopped within a few days. After three-week therapy with adalimumab, capsule endoscopy showed several healing ulcers without bleeding in the distal to the terminal ileum. She continues to be treated with adalimumab, azathioprine, and mesalazine without recurrent bleeding.
