Dialysis patients remain a high-risk group for hepatitis C virus (HCV) infection. The current diagnosis of HCV infection among dialysis patients includes serological assays and nucleic acid amplification technology (NAT) for assessing serum anti-HCV antibody and HCV viremia, respectively. However, current NAT techniques are expensive and labor-intensive and often lack standardization. An assay ...

It is unclear whether serum ALT levels or virological characteristics of hepatitis C virus(HCV) including HCV genotypes and HCV RNA titers, can reflect the degree of histological injury in chronic hepatitis C. The aim of this study was to investigate the relationships between the levels of histological damage and serum ALT levels, HCV genotypes or circulating HCV RNA titers in chronic hepatitis...

Background and Aims: Hepatitis C virus (HCV) can cause hepatocellular carcinoma (HCC) in a significant proportion (≈ 20 %) of individuals with chronic HCV infection (CHC). Currently, CHC is treated with peginterferon and ribavirin, which depending on genotype approximately 50 to 70% of patients are cured. The so-called “extrahepatic HCV infection” or viral replication in regio...

A quantitative hepatitis C virus reverse transcriptase PCR (HCV RT-PCR) assay established in our laboratory was compared with the Roche Amplicor HCV Monitor test kit for agreement of test results and intra-assay variability. Both assays rely on reverse transcription and amplification of extracted RNA from patients' sera together with an internal RNA standard derived from the 5'-noncoding region...

conclusions the quite sensitive in-house taqman real time rt-pcr assay was able to detect and quantify all four main hcv genotypes prevailing around all geographical regions of iran. results the lower limit detection of this in-house hcv real-time rt-pcr was determined as 100 rna copies/ml. inter- and intra-assay coefficient of variation (cv) of this in-house hcv real-time rt-pcr ranged from 0....

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...

BACKGROUND Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Low concentrations of HCV-RNA may be detected in PBMCs of hemodialysis (HD) patients and this could have a great impact on the management of HD patients. OBJECTIVES...
