Chronic intrahepatic cholestasis of sarcoidosis.
The development of the syndrome of chronic intrahepatic cholestasis in five young, black men who had systemic granulomatous disease and clinical features consistent with those of sarcoidosis is described. Clinical and biochemical aspects, similar to those of primary biliary cirrhosis, included pruritus, jaundice, hepatomegaly and striking elevations of serum levels of alkaline phosphatase and cholesterol. (One patient had skin xanthomas.) Mitochondrial antibodies were not found; and survival of the patients (7 to 18 years) exceeded the usual survival of patients with primary biliary cirrhosis. The histologic abnormalities included noncaseating granulomas, chronic intrahepatic cholestasis, increased copper in hepatocytes, progressive diminution in number of interiobular bile ducts, periportal fibrosis and the eventual development of a micronodular "biliary" cirrhosis. The histologic evolution of the disease suggests a slow, progressive destruction of the bile ducts by granulomas. Although the end stage of this syndrome resembles primary biliary cirrhosis, the characteristic nonsuppurative, destructive cholangitis of primary biliary cirrhosis was not present.
