Abstract
Recently, hepatitis GB virus C (HGBV-C) has been recovered from patients with non-A-E hepatitis. However, it has been unclear whether HGBV-C may be related to the development of alcoholic liver disease (ALD) or not. In this study, we determined HGBV-C RNA in sera from alcoholic patients without markers for hepatitis C and B viruses to evaluate the role of HGBV-C in ALD. Serum samples were obtained from 68 patients with ALD and 40 nonalcoholic patients with chronic type C liver disease. HGBV-C RNA was detected in only 3 of 68 (4.4%) patients with ALD, in 2 of 27 patients with hepatic fibrosis, and in 1 of 5 patients with chronic hepatitis. There was no HGBV-C RNA in sera from patients with fatty liver, alcoholic hepatitis, or cirrhosis. Serum levels of AST, ALT, and γ-glutamyltranspeptidase in alcoholic patients with, as well as without, HGBV-C RNA decreased to normal levels after abstinence. In addition, an inflammatory change was not observed in liver biopsy specimens obtained from two HGBV-C-positive patients with alcoholic hepatic fibrosis. Our results clearly suggest that the prevalence of HGBV-C infection in patients with ALD is rare and that HGBV-C may not play an important role in the development of liver disease in alcoholics.
