Versant HCV Genotype 2.0 Assay (LiPA) in Hepatitis C Virus Genotype Determination Testul Versant HCV Genotype 2.0 Assay (LiPA) în determinarea genotipurilor virusului hepatitic de tip C

چکیده
Hepatitis C virus (HCV) is a major cause of chronic liver disease, the prevalence of the infection being currently estimated at approximately 170 milion persons worldwide. HCV isolates have been classified into six main genotypes. Quick and accurate genotyping of HCV is becoming increasingly important for clinical management of chronic infection and as an epidemiological marker. Genotyping methods are frequently based on the analysis of the 5’ untranslated region (5’UTR) of HCV genome, which is not appropriate for the accurate discrimination of HCV strains at a subtype level. The newly developed Versant HCV Genotype 2.0 Assay (LiPA) uses sequence information from both the 5’UTR and the core region allowing the distinction between subtypes 1a and 1b inside genotype 1 and between genotype 1 and subtypes c to l of genotype 6. Hereby, we make a review of the literature evaluating this new genotyping assay.

Hepatitis C virus (HCV) genotyping is a tool used to optimize antiviral treatment regimens. The newly developed Versant HCV genotype assay (LiPA) 2.0 uses sequence information from both the 5' untranslated region and the core region, allowing distinction between HCV genotype 1 and subtypes c to l of genotype 6 and between subtypes a and b of genotype 1. HCV-positive samples were genotyped manua...

For optimal antiviral therapy, the hepatitis C virus (HCV) genotype needs to be determined, as it remains a strong predictor of sustained viral response. In this study, we assessed the number of HCV genotyping results that could not be determined using the commercially available line probe assay (LiPA) (Versant hepatitis C virus genotype 2.0 assay) in a large international panel of samples from...
متن کاملGenotyping hepatitis C viruses from Southeast Asia by a novel line probe assay that simultaneously detects core and 5' untranslated regions.
Hepatitis C viruses (HCVs) display a high level of sequence diversity and are currently divided into six genotypes. A line probe assay (LiPA), which targets the 5' untranslated region (5'UTR) of the HCV genome, is widely used for genotyping. However, this assay cannot distinguish many genotype 6 subtypes from genotype 1 due to high sequence similarity in the 5'UTR. We investigated the accuracy ...

Hepatitis C virus (HCV) isolates have been classified into six main genotypes. Genotyping methods, and especially the widely used line probe assay (LiPA), are frequently based on the 5'-untranslated region (5'UTR). However, this region is not appropriate for discriminating HCV strains at the subtype level and for distinguishing many genotype 6 samples from genotype 1. We investigated the capaci...
