Prevalence and genotypes of hepatitis B virus infection in patients underwent coronary angiography and coronary artery bypass grafting in mazandaran heart center, sari, iran



Prevalence and genotypes of hepatitis B virus infection in patients underwent coronary angiography and coronary artery bypass grafting in mazandaran heart center, sari, iran



Medical Archives 68(5): 320-324



Hepatitis B virus (HBV) infection is a major global health problem in the worldwide that associated with significant morbidity and mortality in cardiac surgery. The available data on HBV distribution and genotyping of HBV are very heterogeneous. Therefore in this study, we tried to indicate the prevalence of HBV infections in cardiac catheterization patients referred to health centers in the north of Iran and identified the HBV genotypes using polymerase chain reaction (PCR). In this cross-sectional study, we studied 2650 patients who underwent selective coronary artery angiography and coronary artery bypass grafting in Mazandaran heart center, Sari, Iran from 2011 to 2013. All serum samples were examined to detect HBsAg by ELISA test. HBV-DNA was extracted from HBsAg positive samples using Mini Elute Kit from Qiagen and determined the genotypes of HBV by PCR using the Master Mix kit with Taq-DNA polymerase enzyme and with type of specific primers. All samples were examined in the virology laboratory of Sari Medical School. The mean age of patients was 59.7±10.9 (range, 20 to 81) year that 1590 (60%) patients were male and 1060 (40%) were female. Seventeen cases (0.08 %) were found with hepatitis B virus infection, and the highest rates of infection were reported among those aged 40-60 years old in this study. We found genotype D the predominant type in this study. This study indicates that the prevalence of HBV endemicity in the north of Iran is low and genotype D is the only genotype in patients infected with HBV.
