title: Etiology and prognosis of cryptogenic liver cirrhosis: possible contribution of hepatitis B virus.
abstract: Three female patients without type B or type C viral hepatitis, alcoholic, metabolic or autoimmune liver disease, were selected from 250 cases with histologically proven liver cirrhosis (M:F = 183:67). All three cases showed at least one positive aspect among three parameters of serum anti-HBc (RPHA, x1), HBV-DNA (gene S, nested PCR) and liver HBs and/or pre-S2 antigen (immunoperoxidase methods). Two cases may suggest a spontaneous disappearance of HBV from sera. Another case may suggest a contribution of mutant HBV which can not be detected by the routine tests. These HBV-related cirrhotic patients have done well clinically and have not been associated with hepatocellular carcinoma during the period from 6 to 12 years of follow-up when compared with 59.6% and 65.4% prevalence of hepatocarcinogenesis in type B and type C hepatitis-associated cirrhosis during the observation period of six and seven years on average, respectively.
