The article “efficacy of hepatitis B vaccine in those who lost hepatitis B surface antigen during follow-up” published recently in Hepatitis Monthly (1), described the efficacy of HBV vaccine in chronic HBV patients who had been found negative for HBsAg and HBV DNA in sera. The manuscript was highlighted by an Editorial in the same issue (2). The manuscript dealt with a group of chronic HBV pat...
Universal infantile hepatitis B virus (HBV) vaccination may lead to an increase in vaccine escape variants, which may pose a threat to the long-term success of massive vaccination. To determine the prevalence of occult infections in Korean vaccinated individuals, 87 vaccinated subjects were screened for the presence of HBV DNA using both the nested PCR protocol and the VERSANT HBV DNA 3.0 assay...
BACKGROUND AND OBJECTIVE Although hepatitis B vaccine immunogenicity is high, certain risk factors such as age, tobacco consumption, obesity and genetic background have been associated with low responsiveness to HBV vaccine. We aimed to evaluate the role of occult hepatitis B virus (HBV) infection in non-responder adults to HBV vaccine in a low endemic area for HBV. MATERIAL AND METHODS A tot...
background occult hepatitis b virus infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the liver and/or in the serum of patients with negative results of hepatitis b s antigen (hbsag) test with or without serological markers of previous viral exposure. the impact of obi in patients with chronic hepatitis c (chc) is still unclear. objectives the aim of this study was to...
In this issue of the Iranian journal of Kidney Diseases, the case report of “Successful Pregnancy in a Kidney Transplant Recipient With Chronic Hepatitis B Virus Infection” by Kashif and colleagues1 confronts us to different challenging topics in nephrology. First, hepatitis B virus (HBV) infection has been discovered after kidney transplantation with a negative report of hepatitis B surface an...
We read with great interest the article, “efficacy of hepatitis B vaccine in those who lost hepatitis B surface antigen during follow-up” by Taheri et al. published in Hepatitis Monthly (1). In this article, the authors assessed the efficacy of HBV vaccine in those who lost their HBsAg without seroconverssion to anti-HBs antibody with no detectable anti-HBs antibody and HBV DNA in their sera. T...
In this work, we have shown that hepatitis C virus (HCV) and hepatitis B virus (HBV) can coexist in the same hepatocyte using double fluorescent in situ hybridization in liver biopsy samples from patients with chronic HCV infection with occult HBV infection. Digital image analysis of hybridization signals showed that the HBV DNA levels in coinfected hepatocytes were lower than those in cells in...
Reactivation of the hepatitis B virus (HBV) has been reported in patients with occult infection (OBI), i.e. HBV surface antigen (HBsAg) negative, HBV core antibody (anti-HBc) positive ± antibodies against HBsAg (anti-HBs) and detectable HBV DNA in serum or liver, receiving immunosuppressive or cytotoxic therapies. Recently, concerns have been raised regarding the risk of HBV reactivation in OBI...
Although overt hepatitis B virus (HBV) infection promotes the onset of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients, the effect of occult HBV infection remains unclear. The aim of this study was to investigate the effect of occult HBV infection on the early-onset of HCC in HCV-infected patients. A total of 173 HCC patients with HCV infection were enrolled and clas...
BACKGROUND Routes of transmission of hepatitis B virus (HBV)/HIV infections are similar and there is a significant rate of co-infection in patients. A study was recently carried out in NHS Fife, Scotland from February 2007 - February 2008 to estimate the prevalence of HBV/HIV co-infection, occult HBV infection and immunisation status against HBV in a cohort of patients with HIV attending the de...
