- W4383912859 abstract "Background: Hepatitis B virus (HBV) infection is considered a major global health problem. The main objectives of the current study is to determine the patterns of expression of the hepatitis B surface antigen (HBsAg) and HBV core antigen (HBcAg) in liver tissue samples obtained from hepatitis B virus-infected Omani patients and to associate between the pattern of the expression of HBsAg and HBcAg with the other clinical parameters and anti-viral therapy. Methods : The expression patterns of HBsAg and HBV core antigen HBcAg were determined by immunohistochemistry (IHC), in 58 formalin-fixed paraffin-embedded liver tissue biopsies obtained from chronic hepatitis B Omani patients. The association between positivity for HBV antigens with gender, age group, histological appearances, and antiviral therapy was determined. Results: IHC-positive staining of HBsAg was demonstrated in 28 patients (48.3%) patients, of whom 4 (6.9%) also showed HBcAg expression. The expression pattern of HBsAg was predominantly cytoplasmic and was seen in 25 (89.3%) of patients, whereas expression of HBcAg was nuclear in 3 (75%) of patients. HBsAg and HBcAg IHC positivity were more common among males than females and among those aged 39–58 years (P = 0.130 and 0.569, respectively). The presence of lymphocytic infiltration in the majority of liver biopsies examined in the present study indicates that the liver damage could be attributed to immunologically mediated events, especially because HBV is a non-cytopathogenic virus. No significant statistical association was found between positivity for HBsAg/HBcAg by IHC and antiviral treatment. Conclusions: Determination of the expression patterns of HBV antigens in liver biopsies obtained from chronic hepatitis B Omani patients and the association between these expression patterns with other clinical histopathological parameters and anti-viral therapy, will contribute greatly to a better understanding of the pathogenesis of HBV in this unique cohort group of infected individuals." @default.
