INTRODUCTION Screening blood donors for blood-borne pathogens is very critical for the recipient's safety. Similar to hepatitis B and C infections, hepatitis G infection is transmitted through contaminated blood and causes acute and chronic hepatitis. Previous reports have shown that the prevalence of hepatitis G virus (HGV) RNA among healthy Saudi donors was 1%-2%. However, the exposure rate o...

OBJECTIVES To study the prevalence and genotype distribution of hepatitis G virus (HGV) in hemodialysis patients in East Anatolia, Turkey. SUBJECTS AND MATERIALS Eighty-nine hemodialysis patients and 30 healthy individuals were analyzed by using reverse-transcriptase nested polymerase chain reaction with primers specific for 5' untranslated region. HGV genotyping was performed by PCR and thre...

The aims of this study were to determine the outcome and the natural history of GBV-C/hepatitis G virus (HGV) infection and to establish the frequency of acute or persistent infections in multiply-transfused individuals and blood donors. We used a GBV-C/HGV RNA polymerase chain reaction (PCR) and an assay evidencing antibodies to the envelop protein E2, which is considered a marker for virus cl...

We evaluated in a series of 33 HCV positive (both RT-PCR and HCV RIBA 2 assays) B cell non-Hodgkin's lymphomas (NHL) patients the prevalence of active and inactive HGV infection by HGV RNA assays (RT-PCR) and anti HGV antibodies directed against E2 structural protein (immunoenzimatic method), a reliable serologic marker of past HGV infection followed by viral clearance. We found only one patien...

We reported previously on an area in Japan where over 30% of the inhabitants were positive for hepatitis C virus (HCV) antibody. In the present study, clinical features of hepatitis G virus (HGV) infection in this area of high endemicity were compared to those in an area where HCV is not endemic. A total of 400 individuals were selected randomly from those who were medically screened for liver ...

We have analyzed the presence of hepatitis C virus (HCV) and hepatitis G virus (HGV) sequences in bone marrow and serum samples from 48 patients of a hematologic outpatient clinic. HCV RNA was detected in 18 (38%) and 15 (31%) and HGV RNA was detected in 6 (13%) and 9 (19%) of serum and bone marrow samples, respectively. In 3 patients, HGV RNA was detectable in bone marrow but not in the serum;...

Nine sets of nested PCR primers from a 2.6-kb region of the hepatitis G virus (HGV) genome at nucleotide positions 5829 to 8421 were designed and used to analyze serum specimens obtained from patients with community-acquired non-A, non-B hepatitis who were HGV RNA positive. One set of primers was found to be most efficient in detecting HGV and was subsequently used to test 162 HCV-positive and ...

Prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis G virus (HGV), and hepatitis E virus (HEV) was investigated among 574 healthy blood donors in Bolivia. HCV RNA and HGV RNA in the serum were identified by a nested reverse transcription-PCR using primers derived from the 5' untranslated region (5' UTR). We also tested for hepatitis B surface antigen (HBsAg) and for the an...

OBJECTIVE To determine the prevalence and clinical significance of hepatitis G virus (HGV) infection in a large cohort of patients with primary Sjögren's syndrome (SS). PATIENTS AND METHODS The study included 100 consecutive patients (92 female and eight male), with a mean age of 62 years (range 31-80) that were prospectively visited in our unit. All patients fulfilled the European Community ...

The evidence of a higher incidence of hepatitis G virus (HGV) infection among patients with hepatocellular carcinoma (HCC) and the relatively high prevalence of patients with primary liver carcinoma without apparent risk factors in our country motivated the present study, the objective of which was to determine the frequency of HGV-ribonucleic acid (RNA) in a series of patients with HCC. The di...
