BACKGROUND Viral hepatitis is a major health problem worldwide. Change in transmission patterns of hepatitis B makes it necessary to re-evaluate its prevalence and risk factors. OBJECTIVES We aimed to determine the prevalence of HBV infection and its related risk factors in Amol city, Northern Iran. PATIENTS AND METHODS As a population based study, a cluster sampling approach was used and 6...

OBJECTIVE To study the frequencies of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, and their associations with hepatocellular carcinoma (HCC) in immigrant Somalis seen at Mayo Clinic in Rochester, Minnesota. PATIENTS AND METHODS We determined the frequencies of HBV and HCV infection and HCC in immigrant Somalis seen at Mayo Clinic from July 1, 1996, through October 3...

PURPOSE The purpose of this study was to characterize roles of serum hepatitis B virus marker quantitation in differentiation of natural phases of HBV infection. METHODS A total of 184 chronic hepatitis B (CHB) patients were analyzed retrospectively. Patients were classified into four categories: immune tolerant phase (IT, n = 36), immune clearance phase (IC, n = 81), low-replicative phase (L...

BACKGROUND Only limited data are available on the prevalence of hepatitis B in patients with proven rheumatic diseases and thus the risk of reactivation under immunosuppressive therapy. OBJECTIVE To analyse hepatitis B serology in patients with rheumatic diseases prior to therapy. METHOD In total, 1,338 patient records were analysed for HBsAg, HBsAb and HBcAb in a cross-sectional, single-ce...

conclusions in comparison with the rate of hbcab positivity reported in other iranian studies, the rate was higher in the present study. there were a few variations, genotypes, and subtypes among the infected injecting drug users. further investigations are needed to unravel the molecular characterization of obi. results sixty-four (28%) participants were hbcab positive, 59 cases were hbcab pos...

Introduction: The hepatitis B virus (HBV) is one health problem in Iran. Occult hepatitis B (OBI) is diagnosed by the detection of HBV DNA in the serum or liver tissue of patients for whom other serology, especially HBsAg and HBcAg, are negative. The current study aimed to determine the prevalence of OBI in patients who refer for chemotherapy. Methods: Al...
