BACKGROUND Chronic hepatitis C virus (HCV) infection is prevalent among patients on renal replacement therapy. Viral genomic differences can contribute to diversities in clinical manifestation. The distribution of HCV genotypes depends on the geographical region and risk factors unique to the patient population. We determined the HCV genotypes in patients on renal replacement therapy in order t...
BACKGROUND Information about genotypes and associated risk factors in hepatitis C virus (HCV) infected patients in Iran is limited. The aim of this study was to identify the HCV genotypes and associated risk factors in a group of HCV infected patients from Iran. RESULTS Genotyping analysis was performed in 156 patients with positive anti-HCV and HCV-RNA. Patients were questioned concerning do...
Five isolates of hepatitis C virus (HCV) RNA from patients with chronic liver disease in Nepal were not classifiable into the known genotypes I/1a, II/1b, III/2a, IV/2b or V/3a using PCR with type-specific primers deduced from the HCV core gene. Their nucleotide sequences were determined for the 5'-terminal 1.5 kilobases and 3'-terminal 1.2 kilobases, covering 30% of the entire genome, and comp...
BACKGROUND AND AIM Chronic hepatitis C virus (HCV) infection is relatively frequent in China. This study investigated the clinical, demographic, and viral and host genetic characteristics that may influence disease manifestations and clinical management. METHODS In this cross-sectional observational study, treatment-naïve Han ethnic adults with recently confirmed chronic HCV infection were en...
The Invader 1.0 assay (Invader HCV Genotyping Assay, version 1.0; Third Wave Technologies, Inc., Madison, WI) has been developed for the rapid differentiation of hepatitis C virus (HCV) genotypes 1 to 6 based on sequence variation within the HCV 5' noncoding (NC) region. In the present study, we evaluated the compatibility of Invader 1.0 with the COBAS MONITOR (COBAS AMPLICOR HCV MONITOR Test, ...
Determination of hepatitis C virus (HCV) genotypes has become increasingly important during the last years for prediction of the clinical course and the outcome of antiviral therapy. Therefore, numerous different methods have been developed to enable HCV genotyping. However, many of them are very laborious and expensive, leading to limited usage in daily routine diagnostics. We have established...
Patients infected with hepatitis C virus (HCV) were examined with four commercial HCV immunoblotting assays and for anti-GOR antibody to ascertain whether serological findings varied with the genotype of the infecting virus. The results indicate that patients infected with different HCV genotypes tend to show different immunoblotting profiles, mainly due to a low prevalence of antibodies to the...
Background: Nowadays, the immune response to hepatitis C (HCV) treatment has become a crucial issue mostly due to the interleukin 28B (IL-28B) polymorphism effects in chronic HCV patients. The aim of this study was to detect the polymorphism of IL-28B gene (rs12979860) in HCV genotype 1 patients treated with pegylated Interferon and Ribavirin. Methods...
Molecular epidemiological studies of hepatitis C virus (HCV) in the Caribbean may help to specify the origin and spread of HCV infection. Indeed, the Caribbean population is intermixed from European and African origins and geographically close to the American continent. We characterized HCV genotypes in the Caribbean island of Martinique. HCV genotypes were analyzed by sequencing or reverse hyb...
The genotypes of French hepatitis C virus (HCV) isolates were investigated by amplification of a domain from the non-structural region 3 (NS3) using nested PCR, followed by hybridization with two genotype-specific probes, F1 (HCV type I-specific) and F2 (HCV type II-specific). Among 119 HCV RNA-positive sera, 91% of samples were NS3 PCR positive. Most samples (83.2%) hybridized with one or the ...
