Treatment of intractable gastrointestinal manifestations of chronic granulomatous disease with cyclosporine

Gastrointestinal manifestations of chronic granulomatous disease of childhood include granulomatous inflammatory bowel disease. Severe colitis and perirectal disease developed in a 12-year-old boy with chronic granulomatous disease while he was receiving interferon gamma therapy. The boy had a deficiency of the 22 kd light chain of the cytochrome b heterodimer. After conventional medical therapy proved to be ineffective, a rapid clinical response was obtained to cyclosporine.
