Abstract
Three patients with chronic hepatitis B infection, two with chronic active hepatitis and cirrhosis, and the third with quiescent cirrhosis, cleared HBsAg from their serum and eventually developed anti-HBs. All three were asymptomatic and had nearly normal serum aminotransferases following loss of HBsAg. Liver biopsy revealed cirrhosis in each patient. With the development of anti-HBs, these patients became serologically indistinguishable from patients with a cryptogenic cirrhosis who had prior unrelated exposure to hepatitis B. Remote chronic hepatitis B infection may be a more common cause of cryptogenic cirrhosis than is commonly appreciated.
