Abstract
Pancreatic insufficiency leading to altered cyclosporine absorption is reported in a 37-year-old man with ulcerative colitis and sclerosing cholangitis. Asymptomatic chronic pancreatitis occurs frequently in patients with ulcerative colitis, and even more commonly when there is coexistent sclerosing cholangitis. However, pancreatic insufficiency has been documented in only one patient previously with ulcerative colitis and sclerosing cholangitis. Pancreatic function testing can help to identify the complex etiology of malabsorption in these patients and is recommended in patients when liver transplantation is contemplated, as pancreatic insufficiency may alter the absorption of cyclosporine.
