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...

background there have been studies regarding the prevalence of hepatitis b surface antigen (hbsag) and anti-hepatitis c antibody (hcvab) in iran. however, the majority of these have reported a variety of rates, depending on their study population, which limits the generalizability of their results to the general population. on the other hand, cultural diversity in the different provinces of ira...

The prevalence of antibodies to hepatitis B core antigen in 552 prime blood donors was of 9.4%. The majority (71.2%) has antibodies to hepatitis B surface antigen. The hepatitis B surface antigen was present in 0.7%, all of them antibodies to hepatitis B core antigen positive.

Hepatitis B immunoglobulin (HBIG) is an effective treatment for hepatitis B, including postexposure prophylaxis of HBV infection, prevention reinfection in liver transplant patients, and reducing sexual transmission. This study investigated the synthesis human IgG antibodies that specifically target HBsAg subtype adr CHL-YN cells, a newly established cell line grows faster than CHO-K1. To achie...

Introduction: Prison, as the most important place for the transmission of infectious diseases, has particular importance, and prison populations are at high risk for infectious diseases like Hepatitis B & C. This study aimed to determine the prevalence of Hepatitis B & C among male inmates in six prisons of different provinces in Iran in 2012. Methods: In...

The objectives of this study were (1) to determine whether there is association between skin tattoos, Hepatitis-B and prisons, (2) to investigate risk behaviors for Hepatitis-B and (3) to describe characteristics of person who have tattoos. Methods. This retrospective study consisted of a self-administered survey, and an ELISA blood test for viral hepatitis B. The study sample consisted of all ...

Anti-idiotype reagents that recognize a common idiotype associated with the combining site of antibodies to hepatitis B surface antigen (anti-HBs) were used to manipulate the immune response to hepatitis B surface antigen in BALB/c mice. The injection of antibodies to the idiotype before antigenic stimulation resulted in an increase in the number of cells secreting immunoglobulin M antibodies t...

The objectives of this study were (1) to determine whether there is association between skin tattoos, Hepatitis-B and prisons, (2) to investigate risk behaviors for Hepatitis-B and (3) to describe characteristics of person who have tattoos. Methods. This retrospective study consisted of a self-administered survey, and an ELISA blood test for viral hepatitis B. The study sample consisted of all ...

The presence of antibodies to hepatitis B core antigen (anti-HBc) has a different implication than with anti-HBs. Anti-HBc antibodies do not distinguish between active or previous infection, nor to they indicate immunity. All hepatitis B carriers and all patients who have previously been exposed to hepatitis B will be positive for total anti-HBc. Chronic hepatitis B carriers have circulating an...
