BACKGROUND Hepatitis C virus (HCV) has different genotypes throughout the world. Since the determination of which antiviral treatment to be applied is related to HCV genotypes, identification of an individual's HCV genotypes prior to antiviral therapy is critical. OBJECTIVES The purpose of this study was to investigate the distribution of HCV genotypes in a large population of Iranian HCV inf...

Hepatitis C virus (HCV) is a major public health problem with more than 130-180 million people infected worldwide. Several studies in different populations have reported the association of human leukocyte antigen (HLA) genotypes, and HCV viral load, and genotypes. The aim of this study was to investigate a possible association between HLA class I and II alleles in HCV-infected patients and heal...

INTRODUCTION Chronic hepatitis C cases diagnosed in Romania were mostly related to unsafe parenteral treatments and blood transfusions; HCV genotype 1b was prevalent. During the last decade, an increasing number of HCV infections was reported among people who inject drugs (PWID). The aim of the current study was to test if this epidemiological shift triggered a diversification of the circulatin...

aim : the purpose of this study was to compare the distribution of interleukin (il)-28b genotypes between iranian healthy individuals and patients with chronic hepatitis c based on the genotype. background : polymorphisms in the region of il-28b gene have been identified as the strongest genetic pretreatment predictor of sustained virological response (svr) in hepatitis c infection. patients an...

We evaluated the Abbott RealTime (ART) and Roche Cobas TaqMan Hepatitis C virus (HCV) viral load assays for quantification of HCV genotypes in patient specimens. The ART HCV assay was a more sensitive and precise tool for accurate HCV viral load quantification across the HCV genotypes tested, especially genotype 1b.

BACKGROUND The hepatitis C virus (HCV) has six major genotypes. The purpose of this study was to phylogenetically investigate the differences between the genotypes of HCV, and to determine the types of amino acid codon usage in the structure of the virus in order to discover new methods for treatment regimes. METHODS The codon usage of the six genotypes of the HCV nucleotide sequence was inve...

Hepatitis C virus (HCV) heterogeneity accounts for the failure of effective vaccine development and the lack of successful anti-viral therapy in some patients. Little is known about the immune response to HCV peptides and the region or race specific genotypes in China. The objective of this study was to characterize HCV antibody immune response to HCV peptides and HCV genotypes in different reg...

The seroprevalence and genotypes of hepatitis C virus (HCV) were studied in 283 patients attending six haemodialysis units in Jordan. In all, 98 (34.6%) patients were anti-HCV-positive by EIA, 92 (93.9%) of whom were also reactive in an immunoblot assay. The prevalence of anti-HCV was correlated with a history of blood transfusion before the introduction of blood donor screening for HCV and wit...

BACKGROUND Hepatitis C Virus (HCV) infection is a global health burden particularly in Egypt, where HCV genotype 4a (GT-4a) predominates. The prevention and control of HCV infection will remain a challenge until the development of an effective vaccine that protects against different genotypes. Several HCV GT-1-based vaccines are in different stages of clinical trials, but antigenic differences ...

BACKGROUND Prevalence rates of hepatitis C virus (HCV) co-infection, the distribution of HCV genotypes, and the frequency of spontaneous resolution of hepatitis C in patients infected with the Human Immunodeficiency Virus (HIV) have a worldwide disparity. The purpose of this study is to investigate the prevalence of HCV antibodies (anti-HCV) in patients with HIV, the proportion and correlates o...
