Excluding acute hepatic failure caused by drugs, the etiology of fulminant hepatitis (FH) remains unknown in many patients. There are conflicting data about a possible pathogenic role for the hepatitis G virus (HGV) in patients with cryptogenic fulminant hepatitis (non-A-E FH). We investigated the presence of circulating HGV in 36 patients with well-documented non-A-E fulminant and 5 patients w...

AIMS To determine whether the recently described flavivirus, hepatitis G virus (HGV), might contribute to the pathogenesis of lymphoma by testing for the presence of HGV RNA in sera from patients attending lymphoma clinics; to compare the incidence of HGV RNA in lymphoma patients with that in normal blood donors; and to look for potential risk factors for HGV infection and for evidence of hepat...

Hepatitis G virus (HGV or GB-C virus) is a newly described virus that is closely related to hepatitis C virus (HCV). Based on sequence analysis and by evaluation of translational initiation codon preferences utilized during in vitro translation, HGV appears to have a truncated or absent core protein at the amino terminus of the HGV polyprotein. Consequently, the biophysical properties of HGV ma...

The natural course and the clinical significance of hepatitis G virus (HGV) infection were investigated in 106 pediatric patients who received chemotherapy for hematological malignancy or underwent bone marrow transplantation (BMT) using HGV-RNA and antibodies to the HGV-E2 protein (anti-E2). HGV markers were detected in 21 patients (19.8%; HGV-RNA in 19 and anti-E2 in 2). Longitudinal analysis...

BACKGROUND Hepatitis G virus (HGV) or GB-virus type C (GBV-C) is, like hepatitis C, a blood-borne virus and a member of the family of flaviviridae. HGV is distributed globally and is present in the volunteer blood donor population. Thus, for epidemiological reasons, HGV is of interest in haemodialysis patients, who are at risk of parenterally transmitted infections. The aim of the present inves...

The parallel measurement of serum antibodies to the hepatitis G virus (anti-HGV) and of viremia (HGV-RNA) should improve our understanding of HGV transmission by coagulation factor concentrates. The aim of this study was to assess the relationship between HGV, the type of concentrate infused, and liver disease in multitransfused hemophiliacs. To this end, anti-HGV and HGV-RNA were evaluated by ...

BACKGROUND AND OBJECTIVE To investigate the prevalence and evolution of hepatitis G virus (HGV) infection in hemophiliacs and to correlate evolution of HGV infection markers with immunologic parameters in those patients co-infected with HIV. DESIGN AND METHODS HGV RNA and anti-E2 antibodies were studied in 124 patients. Serial samples were drawn every 4 months from 1992 to 1996. Lymphocyte su...

Hepatitis G virus (HGV) RNA was detected in 18 of 133 pregnant women from Tanzania without known risk factors for HGV infection and in 7 of 18 children born to HGV RNA-positive mothers. Molecular evidence of mother-to-infant transmission was obtained only for three of seven children. HGV RNA was also detected in 4 of 42 children born to non-HGV-infected women. Thus, mechanisms other than matern...

To assess the persistence of hepatitis G virus (HGV) infection and its association with liver disease, HGV RNA was assessed in the most recent serum sample for 246 long-term injecting drug users (IDUs) and in prior specimens for those found HGV RNA-positive. HGV RNA was detected at the most recent visit in 38 (15.4%). For 31 (82%), HGV RNA was also found at all prior visits occurring a median o...

The role of hepatitis G virus (HGV) infection in acute non-A-E hepatitis was investigated in adults with viral hepatitis. HGV RNA was present in 1 of 28 patients with non-A-E hepatitis but 9 of 22 with hepatitis C (P < .003). HGV RNA-positive patients (HGV-infected and HGV-hepatitis C virus [HCV]-coinfected) developed light-to-moderate jaundice. Clinical and biochemical features of HGV-positive...
