background: hepatitis- b infection is one of the infectious diseases that transmits via blood transfiosion, blood product, injection, mother to fetus and sexual contact. protective anti hepatitis-b titer are observed in more than 90% of healthy children. the aim of this study was to evaluate seroconversion rates in children who received routine vaccination program. methods: a cross sectional st...
BACKGROUND Occult hepatitis B infections are becoming a major global threat, but the available data on its prevalence in various parts of the world are often divergent. OBJECTIVE This study aimed to detect occult hepatitis B virus in hepatitis B surface antigen-negative serum using anti-HBc as a marker of previous infection. PATIENT AND METHODS A total of 1000 randomly selected hepatitis B ...
Serological markers of hepatitis A and B virus infection were determined by radioimmunoassay in 162 university students. Antibody to hepatitis B e antigen (anti-HBe) was demonstrated in 11 of 15 students positive for both antibody to hepatitis B e antigen (HBsAg) and antibody to hepatitis B core antigen (anti-HBc). The presence of anti-HBc alone seemed to denote previous hepatitis B virus infec...
background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...
in order to determine the efficacy of recombinant hepatitis b vaccine in iranian infants, we analyzed the efficacy of a recombinant hepatitis b vaccine in 115 infants aged 12-24 months born to hbsag negative mothers who received three doses of hbv antibody to hepatitis b surface antigen (anti-hbs) was checked after the third dose of the vaccine, 94.8% of the infants had developed protective ant...
Hepaxpert-I is an expert system that interprets the results of routine serologic tests for infection with hepatitis A or B virus. The tests measure antibody to the hepatitis A virus (anti-HAV), IgM antibody to the hepatitis A virus (IgM anti-HAV), hepatitis A virus (HAV) in the stool, hepatitis B surface antigen (HBsAg) and antibody (anti-HBs), antibody to hepatitis B core antigen (anti-HBc and...
BACKGROUND Hepatitis B virus infection is a very common cause of chronic liver disease worldwide. It is estimated that 3% of Iranians are chronically infected with hepatitis B virus. Current population-based studies on both rural and urban prevalence of hepatitis B virus infection in Iran are sparse with results that do not always agree. We performed this study to find the prevalence of hepatit...
Introduction: Hepatitis D virus (HDV) is a 35 nm in diameter agent that depends on hepatitis B surface antigen in order to proliferate and accumulate. Infection with delta agent can occur spontaneously with hepatitis B virus infection and it cause acute hepatitis or develop as secondary infection in the patients with hepatitis B. Hepatitis D virus (HDV) has several genotypes based on genome seq...
Aim: Hepatitis B infection is one of the common diseases worldwide and the most prevalent communicable virus transferred by blood to the healthcare personnel. Active immunity, due to vaccination is the most effective way to prevent hepatitis B infection. The present study aimed at determining protective antibody titer against HBs antigen in Gonabad University of Medical Sciences students in Ira...
