    Author: Schöniger-Hekele M, Petermann D, Lesch OM, Müller C.

    Abstract:
    BACKGROUND: Hepatitis G (GBV-C/HGV) is an RNA-virus belonging to the flavivirus family and is capable of inducing hepatitis in rare cases. Its importance as a co-factor in the pathogenesis of liver disease needs to be clarified. AIMS: To determine the prevalence of HGV in chronic alcoholics with and without liver cirrhosis. PATIENTS: 86 alcoholics, 44 with liver cirrhosis and 42 without liver cirrhosis, were investigated; 93 healthy individuals served as controls. METHODS: Serum was tested for GBV-C/HGV-RNA by reverse-transcription polymerase chain reaction (RT-PCR) and for anti-E2, a marker of resolved GBV-C/HGV infection, by ELISA. GBV-C/HGV-RNA positive samples were sequenced and the GBV-C/HGV subtype determined. RESULTS: Eight out of 86 (9.3%) alcoholics were GBV-C/HGV-RNA positive, as compared to 2 out of 93 (2.2%) healthy controls (n. s.). Twenty-one (24.4%) alcoholics had anti-E2 in serum, whereas this antibody was found in 12 (12.9%) healthy persons only (n. s.). However, significantly more alcoholic patients (33.7%) than healthy controls (15.1%) had past or present contact with GBV-C/HGV (p = 0.006). 11.4% of alcoholic patients with liver cirrhosis and 7.1% of alcoholic patients without liver cirrhosis showed GBV-C/HGV-RNA. 34.1% of alcoholic patients with liver cirrhosis and 16.6% of alcoholic patients without liver cirrhosis had anti-E2. Among the 44 patients with liver cirrhosis, 8 out of 11 (72.7%) patients with variceal bleeding, but only 11 of 33 patients without bleeding had contact with GBV-C/HGV (p = 0.05). Seven out of 8 GBV-C/HGV-RNA positive alcoholics had genotype 2a, 1 had type 1a of GBV-C/HGV. CONCLUSION: Alcoholic patients have a significantly higher contact rate with GBV-C/HGV as compared to healthy controls. Alcoholics with liver cirrhosis tend to be more frequently infected than alcoholic patients without liver cirrhosis. A previous variceal bleeding episode is significantly associated with GBV-C/HGV infection.
