BACKGROUND Hepatitis B virus-associated glomerulonephritis (HBV-GN) is one of the extrahepatic manifestations after HBV infection, which would cause great clinical harm to people. The present study was undertaken to investigate the HBV-GN genotypes and its clinical relevance in Chinese children. METHODS A total of 41 HBV-infected children diagnosed with HBV-GN were enrolled in the study. All ...

We read with great interest the recent article published by Mercier et al. (4) on the overestimation of mixed infections as a result of erroneous genotype H detection by use of the new version of the INNO-LiPA HBV genotyping assay. In this study, the INNO-LiPA assay identified 28 mixed infections in a population of 200 HBsAgand anti-HBcAg-hepatitis B virus (HBV)-DNA-positive French blood donors...

Hemodialysis patients are at high risk for hepatitis B virus (HBV) infection. A survey was conducted in the hemodialysis population of the state of Goiás, Central Brazil, aiming to assess the prevalence of HBV infection, to analyse associated risk factors, and also to investigate HBV genotypes distribution. A total of 1095 patients were interviewed in 15 dialysis units. Serum samples were scree...

In 1988, it was reported that the full nucleotide sequences of 18 hepatitis B virus (HBV) strains clustered into four genetic groups (A to D) with more than 8% divergence between the groups. This classification of strains in terms of genome sequence has since proven to be an important tool in the understanding of HBV epidemiology and evolution and has been expanded to include three more genotyp...

BACKGROUND On-treatment decline of serum hepatitis B surface antigen (HBsAg) may reflect the immunomodulatory effect of pegylated interferon (PEG-IFN) for hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB). We compared HBsAg decline across HBV genotypes between combined responders (HBeAg loss and HBV DNA<10,000 copies/ml at week 78), HBeAg responders (HBeAg loss with HBV DNA>10,00...

Hepatitis B Virus (HBV) manifests high genetic variability and is classifiable into ten genotypes (A-J). HBV infection can lead to variable clinical outcomes, ranging from self-limiting acute hepatitis to active chronic hepatitis, cirrhosis and hepatocellular carcinoma. The present study characterizes HBV strains circulating among patients with acute (AHB) and chronic HBV infection (CHB). Among...

BACKGROUND More than ten subgenotypes of genotype C Hepatitis B virus (HBV) have been reported, including C1 to C16 and two C/D recombinant subgenotypes (CD1 and CD2), however, inconsistent designations of these subgenotypes still exist. METHODOLOGY/PRINCIPAL FINDINGS We performed a phylogenetic analysis of all full-length genotype C HBV genome sequences to correct the misclassifications of H...

BACKGROUND Hepatitis B virus (HBV) gene and protein variations have frequently been observed in chronic patients. The aims of this study were to determine the genotypes as well as the patterns of HBsAg variations in chronically-infected patients from the south-eastern part of Iran. METHODS Twenty- one chronic inactive HBV carriers from Sistan-Balouchestan Province (an area with a low prevalen...

We aimed to identify genomic markers in hepatitis B virus (HBV) that are associated with hepatocellular carcinoma (HCC) development by comparing the complete genomic sequences of HBVs among patients with HCC and those without. One hundred patients with HBV-related HCC and 100 age-matched HBV-infected non-HCC patients (controls) were studied. HBV DNA from serum was directly sequenced to study th...

objectives the present study aimed to evaluate the genotypes and prevalence of mutations in a segment of s and rt gene in hbv isolates in southern khorasan, iran. methods this was a population-based study comprising 5,235 randomized samples for hbv screening. a nested-polymerase chain reaction (pcr) test was followed by direct sequencing, and the sequences blast with present sequences of ncbi d...
