results the prevalence of hbsag, hbsab and hbcab were estimated as 0.9%, 30.7% and 10.5%, respectively. the mean age of all participants was 43.9 (95% ci: 43.4, 44.3) in females and 55.6 in (n = 3472) males. in our study, there was a significant association between family history of hepatitis, rural residency and presence of hbsag. there was also a positive correlation between hbcab and family ...

background despite the advances in the treatment of chronic hepatitis b virus (hbv) infection, liver transplantation (lt) remains the only hope for many patients with end-stage liver diseases resulting from hbv. objectives the aim of this study was to investigate the rate of hbv recurrence in cases that had undergone lt due to the hbv related liver cirrhosis. patients and methods forty-nine pat...

conclusions the mutation ratio difference between genotypes b and c in children was higher than that of adults and several combined mutations were exclusively detected in children with chronic hbv genotype c infection associated with higher viral load. objectives the aim of this study was to assess the mutation profiles of bcp and precore regions in different hbv genotypes in chronically infect...

background hepatitis b virus (hbv) covalently closed circular dna (cccdna) served as a vital role in the life cycle of the virus and persistent infection. however, specific and quantitative methods for cccdna detection have not been available. objectives our aim was to develop and primarily evaluate a quantitative method for hbv cccdna based on magnetic capture hybridization and quantitative pc...

abstract background: investigators were suspicious of tyrosine-methionine-aspartate-aspartate (ymdd) mutations occurred only in patients who were treated by lamivudine. however, ymdd mutations of hepatitis b virus gene (hbv dna) in patients with chronic hepatitis b (chb) untreated with antiviral medicines was reported in some studies. the aim of this study was to evaluate ymdd mutations in iran...

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...

context since the introduction of highly active anti-retroviral regimen for human immunodeficiency virus-1 infection, a significant increase in the incidence of hepatocellular carcinoma has been reported in patients already chronically infected with hepatitis b virus and then given this form of regimen for their retroviral infection. evidence acquisition this phenomenon was initially attributed...

Background: Infections due to the hepatitis B (HBV) and hepatitis C (HCV) viruses constitute a global public health problem. Although screening of these infections remains a pivotal tool for timely detection and management of carriers, this preventive measure has been neglected in Africa. Objective: The current study determined the prevalence of hepatitis...

hepatitis b infection is the main cause of liver related mortality in many countries including iran. liver transplantation in cirrhosis due to hbv infection before 1990 was an absolute contraindication. recurrent infection was a significant event in post liver transplant setting and resulted in increased risk of graft failure and death except successful transplanted individuals. advances in ant...

results there were 64 women and 936 men in the population under study. the mean ± sd age of the donors was 38 ± 11 years. 80 out of 1000 samples (8%) were found to be positive for hbcab. hbv dna was detected in 50% of hbcab positive specimens. the mean ± sd age of donors without hbv dna was 37.7 ± 10.5 years and for donors with hbv dna was 40.9 ± 11.2 years (p = 0.05). objectives the aim of thi...
