Background: To determine the possible sources for the transmission of Hepatitis B Virus (HBV) infection to children in Babol, North of Iran.Methods: Forty-five boys and 35 girls with the mean age of 9.2±5.1 years were evaluated from 1993 to 2004. Hepatitis B viral markers in all the family members were assessed. The risk factors for other sources were also determined.Results: Sixty-five (81.3%)...

background co-infection with human immunodeficiency virus (hiv) and hepatitis b virus (hbv) is common due to shared routes of transmission, as reported approximately 10% of 33 million hiv-infected patients worldwide are chronically infected with hbv. mutations of hbsag especially within the “a” determinant could alter the antigenicity of the protein, causing failure of hbsag neutralization and ...

  Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA ...

Background & Aims HBV genotype G (HBV/G) is mainly found in co-infections with other genotypes and was identified as an independent risk factor for liver fibrosis. This study aimed to analyse the prevalence of HBV/G healthy European carriers characterize crosstalk genotypes. Methods A total 560 were tested via HBV/G-specific PCR co-infections. Quasispecies distribution analysed deep sequencing,...

Background: The outcome of Hepatitis B virus (HBV) infection is chronic or resolved HBV infection. Over the time, the levels of HBsAg or Anti-HBs declined and were not detectable in their sera and was named as isolated anti-HBc. The purpose of this study was to assess the prevalence of isolated anti-HBc in previously HBV infected individuals.Methods: From April 2000 to September 2008, the resul...

    Abstract   Background: Hepatitis B virus infection is an important cause of liver morbidity and   mortality worldwide. HDV changes the natural course of HBV. The prevalence of HDV infection wasn’t determined in the various groups of HBV infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and HCC) in Iran. We aimed to research the prevalence of hepatitis D virus infection in v...

Background: Due to their similar routes of transmission, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection occurs considerably. HBV infection progresses more rapidly in HIV-infected patients. Therefore, HBV vaccination of all non-immune HIV infected patients is recommended. On the other hand, HIV-infected subjects have suboptimal responses to HBV vaccine. In this study...

 ABSTRACT One of the best reliable markers of hepatitis B virus infection is antibodies to the core antigen (Anti-HBc). A first-time blood donor with HBsAg positivity was identified as an HBV carrier that was anti-HBc negative. The patient was followed for 24 months in order to investigate the evolution of his HBV serological profiles and HBVDNA (PCR). In the follow-up for 24 months, HBsAg, HBe...

conclusions patients with hiv/aids are more likely to acquire other stis, because the same behaviors that increase the risk of becoming hiv infected can also increase the risk of acquiring stis. having a sore on the skin due to an sti can make the transmission of hiv to the sex partner more likely than people who don’t have such sore in their genital area. results among the 41 patients with hiv...

background: the outcome of hepatitis b virus (hbv) infection is chronic or resolved hbv infection. over the time, the levels of hbsag or anti-hbs declined and were not detectable in their sera and was named as isolated anti-hbc. the purpose of this study was to assess the prevalence of isolated anti-hbc in previously hbv infected individuals.methods: from april 2000 to september 2008, the resul...
