Objective: This study was conducted to screen the hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B e antigen in pregnant women. Methods...

methods and materials: hepatitis b virus dna was detected by conventional pcr in some of the serum samples obtained from hbsag-positive chronic hepatitis b (chb) patients who were referred to health centers of shahrekord for routine monitoring of the disease. subsequently, using real-time pcr, the dna samples were used for genotyping and analysis of resistance to lamivudine. results: the dna wa...

conclusions the results showed a declining trend in anti-hbsab titers over the time after vaccination against hepatitis b virus in our region. further studies are warranted to establish the need for a booster dose in cases that are at risk of hepatitis b virus infection. results hepatitis b seroprotection rates (anti hbsab ≥ 10 iu/l) among vaccinated children and adolescents aged 1 and 18 years...

conclusions in our study, only hbv genotype d was found among all the positive hbsag and occult hbv infection. moreover, high prevalence (40.7%) of occult hbv infection was determined among patients suffered from cryptogenic cirrhosis. results eleven (40.7%) out of 27 hbv cryptogenic cirrhosis and all 11 hbsag-positive patients were positive for hbv dna. the seroprevalences of hepatitis b virus...
