Effectiveness of infliximab in common variable immunodeficiency associated with enteropathy.

Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency in adults, with non-infectious gastrointestinal involvement present in up to 50 % of patients, with the small intestine and colon being the most affected areas. Reports have evaluated the effectiveness of biologic therapy in this scenario. Here, we describe the clinical, endoscopic, and histological findings of a patient who presented a satisfactory response to infliximab.
