Abstract
Autoimmune enteropathy is a rare condition seen in adults with limited therapeutic options available. It manifests with profuse diarrhea and malnourishment. The diagnosis is made through a combination of clinical, serologic, and histologic parameters. The cornerstone of therapy revolves around nutritional optimization and immunosuppression, most commonly in the form of corticosteroids. Alternate therapies, such as antitumor necrosis factor agents, can be considered if there is an inadequate response to steroids. We report a case of autoimmune enteropathy that was successfully treated with adalimumab, a rare treatment for an infrequent disease.
