BACKGROUND AND OBJECTIVE Blood-borne infections, such as the HIV virus and hepatitis B and C, are major problems in patients receiving blood products. Here we examined the prevalence of HTLV-1, HCV, HBV, and HIV in hemophilic patients. METHODS A cross-sectional study on 108 hemophilic patients (101 males and 7 females) involved detection of HBV, HCV, HIV and HTLV-1 infections using immunoassa...

BACKGROUND Single-nucleotide polymorphisms in microRNAs play important roles in oncogenesis and cancer development. Objective. We aim to explore whether miR-646 rs6513497 is associated with the risk of hepatocellular carcinoma. METHODS Total 997 HCC patients and 993 cancer-free controls were enrolled in this study. Genotyping was performed using MassARRAY method. RESULTS Compared with the T...

OBJECTIVE To investigate the distribution of hepatitis B virus (HBV) genotypes among patients with chronic hepatitis B in Kayseri, Turkey. METHODS The study took place in the Department of Microbiology, Erciyes University, Kayseri, and Iontek Laboratory, Istanbul, Turkey, from January 2005 to October 2007. One hundred and ten patients with chronic hepatitis B were included in this study. Hepa...

I read with interest the recent research article by Sami and colleagues, entitled “Emergence of Hepatitis B Virus Genotype F in Aligarh Region of North India” published in the Advances in Virology. In this paper the authors report the emergence of hepatitis B virus (HBV) genotype F in North India. The paper is of significant importance from themolecular epidemiological perspective, since circul...

It is common to observe the clustering of chronic hepatitis B surface antigen (HBsAg) carriers in families. Intra-familial transmission of hepatitis B virus (HBV) could be the reason for the familial clustering of HBsAg carriers. Additionally, genetic and gender factors have been reported to be involved. We conducted a three-stage genome-wide association study to identify genetic factors associ...

Introduction The overall health status of workers of tea garden of Bangladesh is below the national standard. Also, almost nothing has been reported about status of hepatitis virus infection among these population and there is also a lack of consensus. Materials and methods Several health-related facts, especially those of liver diseases, were collected from 130 workers of tea garden via ques...

A nested polymerase chain reaction (PCR) protocol was developed for rapid genotyping of hepatitis B virus (HBV). During the first PCR round, a universal HBV primer pair was used to amplify the entire pre-S region of the HBV genome. Within the pre-S region, many nucleotide exchanges are observed. These are partly correlated to the serological hepatitis B surface antigen subtypes. Five additional...

The prevalence, virological and epidemiological aspects of the hepatitis C virus (HCV) and the hepatitis B virus (HBV) infections vary among hemodialysis patients in different countries. Aiming at analyzing these aspects of HCV and HBV infections in hemodialysis patients in Belo Horizonte, MG, Brazil, we studied three hemodialysis units including 434 patients. Serology was used to detect anti-H...

INTRODUCTION Hepatitis delta virus (HDV) is a serious cause of liver-related mortality in patients infected with hepatitis B virus (HBV). Determination of genotypes of HDV and phylogenetic analysis are important for better understanding the pathogenesis of the liver diseases associated with HBV infection. The aim of this study was to determine the genotype or genotypes of HDV among chronically ...
