â  â  background non-alcoholic fatty liver disease/steatohepatitis (nafld/nash) is the most common form of chronic liver disease woldwide and is no longer considered a benign disease. its prevalence has not been deterâ­mined in a large-scale population-based study in iran. me t hod s a total of 6583 individuals aged 18 to 65 were randomly selected from three geographically distinct provinces in...

     Thimerosal, which is approximately 50% mercury by weight is a preservative widely used in vaccines since the 1930’s. It meets the requirements for a preservative as set forth by Pharmacopeia challenge test and has been shown to be effective against a broad spectrum of pathogens. In July 1999, the Public Health Service agencies and vaccine manufacturers agreed that thimerosal should be redu...

The hepatitis C virus (HCV) nonstructural 3 (NS3) protein is composed of an amino terminal protease and a carboxyl terminal RNA helicase. NS3 contains major antigenic epitopes. The antibody response to NS3 appears early in the course of infection and is focused on the helicase region. However, this response cannot be defined by short synthetic peptides indicating the recognition of conformation...

conclusions our study suggested that the prevalence rate of hepatitis c virus is below 1% in the general population of mashhad. results in this study the overall seroprevalence of hepatitis c was founded to be 0.2% by using elisa method. however, the overall hepatitis c virus infection prevalence was found to be 0.13% with rt-pcr method. patients and methods three thousand, eight hundred and se...

background with the advent of highly effective anti-hepatitis c virus (hcv) drugs, efforts to identify infected cases, high-risk groups, and associated risk factors have become the focus of current control measures. objectives to determine the prevalence of the hcv antibody among diabetics and patients with lymphoproliferative disorders (lpd) who presented to the outpatient clinics of a univers...

Autoimmune responses were observed in a large proportion of hepatitis C cases and are suspected to be part of viral pathogenesis. The AN6520 antigen (AN-Ag) is a normal cellular protein mainly expressed in liver that was found associated with non-A, non-B hepatitis. To elucidate its pathogenic role in hepatitis C, we developed an IgM capture assay using purified AN-Ag and confirmed that the ant...

800x600 background : hepatitis b and c infections have remained major global health burdens during the most recent century. the viral agents responsible for these diseases share common modes of transmission with human immunodeficiency virus (hiv) such as needle-sharing in iv drug abusers. coinfection of hepatitis b or c with hiv increases the rate of progression of chronic liver disease. given ...

background: thalassemia patients are more susceptible to hepatitis than the normal population due to the frequent blood transfusions. objective: to determine the immune response of children with major ß-thalassemia, by measuring anti-hepatitis b surface antibody (anti-hbs ab) following the last hbv vaccine injection. methods: this study was carried out on 215 thalassemic children who received t...

INTRODUCTION We set out to determine the seroprevalence of hepatitis B and hepatitis C viruses among human immunodeficiency virus infected individuals and its impact on pattern of presentation. METHODOLOGY A serological study for hepatitis B and hepatitis C viruses was performed on 260 HIV-positive individuals. These patients were tested for the presence of hepatitis B surface antigen and ant...
