long-term protection against hepatitis b virus (hbv) is dependent on persistence of anti-hbs antibodies and/or strong immunological memory. in this study we evaluated the persistence of anti-hbs antibodies in healthy iranian children 5 years after primary vaccination and the response to a booster dose using recombinant hepatitis b vaccine. totally, 81 children who had received primary course of...
A 51-year-old man who was hepatitis B surface antigen (HBsAg)-negative and positive for anti-hepatitis B surface antigen (anti-HBs) and anti-hepatitis B core antigen (anti-HBc), during rituximab therapy for chronic Lymphocytic leukemia, developed reactivation of hepatitis B virus (HBV) infection with hepatitis that proceeded towards hepatic failure and death in spite of lamivudine therapy. HBsA...

AIM To assess the seroprevalence of hepatitis B virus (HBV) immunity among previously vaccinated pediatric liver transplant recipients and present a case report of de novo hepatitis B infection after liver transplantation. METHODS This study focused on children with chronic liver diseases who received primary hepatitis B immunization and had a complete dataset of anti-HBs before and after liv...
Background: Following WHO recommendation, HBV vaccination has been integrated into EPI program in Iran since 1996. Objective: To evaluate the immunogenicity and protective effect of HB vaccine (recombinant Heberbiovac ,Cuba ) in vaccinated children and adults . Methods: A total of 542 cases (340 children and 202 adults) were vaccinated using a three-doses schedule of zero, one and six month. ...
BACKGROUND Neither HBV DNA nor HBsAg positivity at birth is an accurate marker for HBV infection of infants. No data is available for continuous changes of HBV markers in newborns to HBsAg(+) mothers. This prospective, multi-centers study aims at observing the dynamic changes of HBV markers and exploring an early diagnostic marker for mother-infant infection. METHODS One hundred forty-eight H...
A total of 250 dentists (53.6% men and 46.4% women), with a mean age of 35.1 ± 9.8 years, were submitted to serological tests for the diagnosis of hepatitis B (HB) – HBsAg, anti-HBs, anti-HBc, HBeAg, and anti-HBe – using a radioimmunoassay. One or more of these markers were detected in 78 individuals (31.2%) who were excluded from the group to be vaccinated. Of the 172 HB-susceptible individual...
AIM:To develop a safe and effective DNA vaccine for inducing humoral and cellular immunological responses against hepatitis B virus surface antigen (HBsAg).METHODS:BALB/c mice were inoculated with NV-HB/s, a recombinant plasmid that had been inserted S gene of hepatitis B virus genome and could express HBsAg in eukaryotes. HBsAg expression was measured by ABC immunohis tochemical assay, generat...
background: antibody production in patients with end-stage kidney disease impairs due to several mechanisms. there are different ways to improve response rate to hepatitis b (hb) vaccine. in this study we evaluated the effect of tetanus-diphtheria toxoid (td) vaccine on hbs antibody (ab) level while being given simultaneously with hb vaccine. methods: we recruited 43 hemodialysis and 20 perito...
BACKGROUND Since its development in the early 1980s, Hepatitis B virus (HBV) vaccine has been proven to be highly protective. However, its immunogenicity may be ineffective among HIV-infected children. In Morocco, HBV vaccine was introduced in 1999, and since then all infants, including vertically HIV-infected infants, have been following the vaccination schedule, implemented by the Moroccan mi...
