In order to investigate the prevalence of GB virus C (GBV-C)/hepatitis G virus (HGV) infection in dialysis patients and kidney transplant recipients in Central Brazil and also to analyze the virus genotypes distribution, a total of 123 patients including 98 on hemodialysis, 13 on continuous ambulatory peritoneal dialysis treatment, and 12 who received kidney transplantation were interviewed in ...

Hepatitis G virus (HGV)/GB virus C (GBV-C) causes persistent, non-pathogenic infection in a large proportion of the human population. Epidemiological and genetic evidence indicates a long-term association between HGV/GBV-C and related viruses and a range of primate species, and the co-speciation of these viruses with their hosts during primate evolution. Using a combination of covariance scanni...

The prevalence of GB virus C/hepatitis G virus (GBV-C/HGV) infection among intravenous drug users (IVDUs), patients with liver diseases, and blood donors in Nanning, southern China was studied. GBV-C/HGV RNA was detected by reverse transcription polymerase chain reaction with primers derived from the 5'-untranslated region. GBV-C/HGV RNA was detected in 64 of 85 IVDUs, 20 of 80 persons with liv...

The hepatitis G virus (HGV) polyprotein was scanned by computer-aided prediction of antigenicity to search for B-cell epitopes. Four polypeptide sequences, V37D (amino acids [aa] 1685 to 1721), V36S (aa 2102 to 2137), P37R (aa 2156 to 2192), and C40P (aa 2280 to 2319), were identified and synthesized for use in immunoassays. Antibodies to these peptides were searched for in a panel of 239 serum...

Hepatitis G virus (HGV) nonstructural protein 3 (NS3) contains amino acid sequence motifs typical of ATPase and RNA helicase proteins. In order to examine the RNA helicase activity of the HGV NS3 protein, the NS3 region (amino acids 904 to 1580) was fused with maltose-binding protein (MBP), and the fusion protein was expressed in Escherichia coli and purified with amylose resin and anion-exchan...

BACKGROUND Epidemiological data indicate that Hepatitis G virus (HGV) is transmitted predominantly through parenteral routes, with a high seroprevalence among injection drug users (IDUs), although sexual transmission has also been reported. In this study our objective was to compare the frequency of HGV infection in two groups of HIV-positive patients including IDUs and those with sexual risk o...

GBV-C or hepatitis G virus (HGV) was discovered by two independent groups of investigators when studying cases of hepatitis non-A, non-B, and non-E.1,2 HGV is transmitted through blood transfusion and components.3,4 Up to now, there is no report about detection of GBV-C/HGV RNA by nucleic acid test and serological markers in Chinese voluntary blood donors. Considering the safety of blood transf...

The role of GB virus C/hepatitis G virus (GBV-C/HGV) in adult and pediatric liver disease is unclear. We detected serum GBV-C/HGV RNA by reverse transcriptase polymerase chain reaction in 1 (3%) of 38 cholestatic infants, in 4 (4%) of 95 children without liver disease, and in none of 30 children with autoimmune hepatitis. One cholestatic infant had antibodies, presumably maternal, to GBV-C/HGV....

BACKGROUND & OBJECTIVE Association of hepatitis G virus (HGV) with acute viral hepatitis (AVH) and fulminant hepatitis (FH) is not clearly understood. This study was designed to asses the occurrence of HGV infection and its relationship with other hepatotropic viruses in patients with FH and AVH and also to determine the nucleotide sequence of HGV isolates. METHODS The study included 100 pati...

Serum samples from 96 Spanish hemodialysis patients, as well as serial dilutions of RNA extracted from a reference strain of hepatitis G virus (HGV), were tested for HGV or GB virus C (GBV-C) RNA. Two different reverse transcription (RT)-PCR-based methods of detection were compared for the ability to detect RNA extracted from the samples: an RT-nested PCR assay with primers derived from the 5' ...
