BACKGROUND AND OBJECTIVES Hepatitis C Virus genotyping appears to be vital for predicting the response to antiviral therapy. The present study aimed to analyze the HCV genotypes in relation to persistence or clearance of the virus in residents of Hamadan Province, West-Iran. MATERIAL AND METHODS A total of 1159 recorded questionnaires of HCV infected people were evaluated in this prospective ...

conclusions findings of the present study showed that hcv genotype 3 was the predominant genotype followed by the subtypes 1a and 1b in yazd, central province of iran. in addition, there was no difference between hcv load and genotypes 1 and 3. hcv genotyping is recommended in other provinces of iran. objectives the main aim of this study was to estimate the prevalence of hcv genotypes in yazd,...

The objective was to develop a method of HCV genome sequencing that allowed simultaneous genotyping and NS5A inhibitor resistance profiling. In order to validate the use of a unique RT-PCR for genotypes 1-5, 142 plasma samples from patients infected with HCV were analysed. The NS4B-NS5A partial region was successfully amplified and sequenced in all samples. In parallel, partial NS3 sequences we...

AIM To review Hepatitis C virus (HCV) prevalence and genotypes distribution worldwide. METHODS We conducted a systematic study which represents one of the most comprehensive effort to quantify global HCV epidemiology, using the best available published data between 2000 and 2015 from 138 countries (about 90% of the global population), grouped in 20 geographical areas (with the exclusion of Oc...

today, chronic viral hepatitis is considered as a public health problem in the world. totally, 5% of the world population, especially in asia and africa suffer from this problem. the prevalence of acute hepatitis in america is 0.1-0.2 percent, 50% of those with hepatitis c (hcv) and 5-10% of them with hepatitis b (hcv) develop chronic hepatitis. determining hbv and hcv genotypes is important to...

The immunogenicity of variable regions of hepatitis C virus (HCV) proteins was studied by ELISA by using 543 synthetic peptides from 120 variable regions and 90 sera from HCV-infected patients. Some regions from certain genotypes were less immunogenic, or even non-immunogenic, compared with their equivalents in other genotypes. However, the mean recognition of all peptides from genotypes 1a, 1b...

background and objectives : hepatitis c virus genotyping appears to be vital for predicting the response to antiviral therapy. the present study aimed to analyze the hcv genotypes in relation to persistence or clearance of the virus in residents of hamadan province, west-iran. material and methods : a total of 1159 recorded questionnaires of hcv infected people were evaluated in this prospectiv...

The current study was designed to determine the Hepatitis C Virus (HCV) genotypes in a representative sample of HCV chronically infected patients in Saudi Arabia. All HCV isolates were genotyped by sequencing of the 5'UTR region and newly identified HCV isolates were identified. Specific universal primers targeting 5'UTR region were used for both amplification and sequencing of all isolates tha...

BACKGROUND Genotyping of the hepatitis C virus (HCV) and assessment of viral load is important for designing therapeutic strategies and region specific diagnostic assays. OBJECTIVES To determine the distribution of HCV genotypes among patients attending a tertiary care hospital in south India, and to correlate this with viral load. STUDY DESIGN Ninety HCV RNA positive patients were recruite...

background: hepatitis c is a disease with significant global impact. the distribution of hepatitis c virus (hcv) genotypes in mashhad (the northeast and the biggest city after the capital of iran) is unknown. the purpose of this study was to determine the prevalence of hcv genotypes among hcv seropositive patients, and to study the relationship between types, virologic and demographic features ...
