Primary sclerosing cholangitis associated with inflammatory bowel disease in Cape Town, 1975 -1981
Abstract
Patients with inflammatory bowel disease and serum akaline phosphatase persistently raised to more than twice the normal level were investigated to assess the frequency of primary sclerosing cholangitis (PSC) in the Gastro-intestinal Clinic from 1975 to 1981. Twelve patients had a persistently raised alkaline phosphatase level of hepatic origin, 9 out of 250 with ulcerative colitis and 3 out of 164 with Crohn's disease. PSC was demonstrated in 8 (3%) of the patients with ulcerative colitis, and carcinoma of the pancreas in the remaining 1. Three of the patients with PSC also had gallstones. The colitis antedated the biliary symptoms and signs in all but 1 patient. There was no correlation between the duration, extent and activity of the colitis and the development and outcome of the liver involvement. Investigations in the 3 patients with Crohn"s disease revealed the presence of PSC in 2 (1,2%) and chronic active hepatitis in the 3rd. Of the 2 with PSC, one had cholelithiasis and has had recurrent episodes of cholangitis. The other has had only mild symptpms.
