BACKGROUND GB Virus C is a blood-borne virus and a member of Flaviviridae, like hepatitis C that is distributed globally and puts hemodialysis patients at high risk of developing liver disease. The clinical significance of GBV-C in this population remains unclear. OBJECTIVES The current study aimed to evaluate GBV-C infection among hemodialysis patients. PATIENTS AND METHODS Totally, 149 pa...
Background and purpose: Vaccination is the most effeetive method of prophylaxy in high risk group of hepatitis B. Some individuals faile to respond to triple doses of vaccine which is potentially dangerous. Therefore, immunogenecity of triple doses recombinant hepatitis B vaccine was evaluated in a high risk group (medical sciences students). Materials and Methods: 193 healthy medical scie...
Background: Superinfection of hepatitis A in chronic hepatitis B and C may worsen the course of disease. This study attempted to study frequency of hepatitis A virus antibodies in patients with hepatitis B and hepatitis C. Materials and methods: 115 hepatitis C and 56 hepatitis B patients who visited the Hepatitis Association of Hamedan province during 2004-2005 were enrolled. Hepatitis A viru...
Mild elevations in levels of the liver enzymes alanine transaminase and aspartate transaminase are commonly discovered in asymptomatic patients in primary care. Evidence to guide the diagnostic workup is limited. If the history and physical examination do not suggest a cause, a stepwise evaluation should be initiated based on the prevalence of diseases that cause mild elevations in transaminase...
A specific enzyme immunoassay (EIA) for the diagnosis of hepatitis C virus (HCV) infection was developed by recombinant DNA technology. Abbott HCV EIA was used to detect antibody to HCV (anti-HCV) in non-transfused and multiply-transfused thalassemia patients. None of 11 non-transfused patients had anti-HCV but 3 of 52 (5.8%) multiply-transfused patients had anti-HCV. This study showed that the...
Serological antibody assays used in hepatitis C virus diagnosis have improved in sensitivity and specificity. However, detection of active viremia or monitoring levels of virus during or after patient treatment is most commonly undertaken using nucleic acid-based technologies. Advancements in diagnostic technologies and implications for managing patients with hepatitis C in various clinical set...
Background and Aim: Hepatitis B virus is the cause of acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Its prevalence has been reported to be 0.1%-0.5% and 1.6%-6.5% in the United States and Iran respectively. At present, the only sure preventive measure is vaccination but it does not create absolute (100%) immunity. Antibody production is between 79% to 90%, which occurs t...
Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
Hepatitis B is a liver inflammation caused by hepatitis B virus (HBV) and can be diagnosed in clinical stage by hepatitis B core antibody from IgM class (anti-HBcIgM). Hepatitis B core antibody from IgG class (Anti-HBcIgG) appears quickly after IgM, reaching high titers in chronic hepatitis, and remains even after cure. Since hepatitis B core antibody (anti-HBc) is the first antibody identified...
