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...
Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the main causes of severe liver failure worldwide. This study was conducted to evaluate the incidence rate and trend of these infections over six successive years from 2008 to 2013 in Ilam Province, western Iran. Methods: We studied the registered data of HBV and HCV based on the National Notifiable Diseases Surveil...
today, chronic viral hepatitis is considered as a public health problem in the world. totally, 5% of the world population, especially in asia and africa suffer from this problem. the prevalence of acute hepatitis in america is 0.1-0.2 percent, 50% of those with hepatitis c (hcv) and 5-10% of them with hepatitis b (hcv) develop chronic hepatitis. determining hbv and hcv genotypes is important to...
Background and Aims: Occult hepatitis B virus infection (OBI) is known as an important source of hepatitis B virus (HBV) infection. It is categorized as Hepatitis B surface antigen (HBsAg) not being present and low DNA viral load in serum. In this study, an attempt was made to investigate the outbreak of anti-HBc and OBI among the HBsAg-negative donors in Golestan province. Materials and Metho...
background the occult hepatitis b infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the sera or in the liver biopsy and the absence of hepatitis b surface antigen (hbsag) by serological test. objectives the current study aimed to evaluate the occult hbv infection by polymerase chain reaction (pcr) and determine hbv genotyping among the patients with abnormal alanine t...
BACKGROUND Hepatitis B virus (HBV) has been reported as a coinfection with hepatitis C virus (HCV), hepatitis D virus (HDV), cytomegalovirus (CMV), and human immunodeficiency virus (HIV). CASE REPORT A 34-year-old female presented to our clinic with epigastric pain and severe acute hepatitis manifested as jaundice associated with hyperbilirubinemia, elevated transaminases, and coagulopathy. The...
Background: Nearly 300 million people worldwide are carriers of the Hepatitis B Virus (HBV). Thalassemia and dialysis patients are of the most important individuals at risk for the virus. Despite vaccination, antibody is reduced and there is a possibility of infection to HBV. This study, examines hepatitis B serologic markers among thalassemia and dialysis patients of Mazandaran province, Iran....
Introduction: Hepatitis B virus (HBV) infection is a major health problem worldwide and may lead to serious clinical complications, including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The host’s genetic background in immune system genes is a crucial etiologic factor in progression of HBV infection to chronic disease or clearance of the virus from the body. Interleu...
Hepatitis B Virus (HBV) infection is a major health problem in the developing countries counting Pakistan. This study aimed to examine causes and molecular prevalence of HBV district Bannu Khyber Pakhtunkhwa province,
conclusions fulminant hepatitis b is associated with distinct mutational patterns of hbv, underlining that genomic diversity of the virus is an important factor determining its pathogenicity. results the most commonly detected diversities affect regulatory motifs of hbv in the core and s region, indicating that these alterations may convert the virus to an aggressive strain. moreover, mutations...
