conclusions the results showed a declining trend in anti-hbsab titers over the time after vaccination against hepatitis b virus in our region. further studies are warranted to establish the need for a booster dose in cases that are at risk of hepatitis b virus infection. results hepatitis b seroprotection rates (anti hbsab ≥ 10 iu/l) among vaccinated children and adolescents aged 1 and 18 years...

patients and methods five hundred and sixteen serum samples of the patients undergoing hemodialysis and kidney transplantation from various cities of khuzestan province were collected. anti-hepatitis g e2 antibodies were investigated by elisa method. rnas were extracted from serums and hepatitis g rna was detected by rt-pcr. results of the 516 samples, 38 (7.36%) specimens were positive for ant...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

Hepatitis B virus (HBV) is an etiological agent of hepatitis B infection. Hepatitis B is a life-threatening disease that affects the liver. The clinical outcomes of the disease are varied from asymptomatic disease to serious complication such as cirrhosis and hepatocellular carcinoma (HCC). Despite availability of the vaccine and appropriate treatment, hepatitis B infection still remains a majo...

Co infection with hepatitis C virus and hepatitis D virus (HDV) is less common than that with HIV and HCV, although more attention has been given to HCV co infection as a result of its higher frequency of chronic disease. The present investigation was attempted to determine the exact prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) infection among liver...

Five nonoverlapping antigenic sites (sites I through V) of woodchuck hepatitis virus surface antigen were identified with competitive binding assays involving monoclonal antibodies. Site I contributed to cross-reactions among surface antigens of hepatitis B-like viruses infecting woodchucks, ground squirrels, and humans. At least three distinct sites (sites I, II, and III) are responsible for c...

SUMMARY To investigate the relationship between studying in the field of laboratory sciences and some of markers of Hepatitis B virus, the prevalence of Hepatitis Bs Ag, Hepatitis Be Ag and their antibodies, were studied in 423 students of Tehran Universities. Using the enzyme linked immunosorbent assay (ELISA) method, it was found that 1.4 % of laboratory sciences students possessed HBsAg,9% ...

An enzyme-linked immunosorbent assay for the detection of immunoglobulin M (IgM) antibodies to hepatitis A virus is described. The test uses the principle of binding of IgM antibodies to anti-IgM-coated microtiter plates to determine whether the IgM antibodies attached have specificities for hepatitis A virus. In three patients with hepatitis type A followed up to 12 months, IgM antibodies to h...

Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...

A 37-year-man with chronic hepatitis B was diagnosed as having antimicrosomal antibodies and subclinical hypothyroidism. The association of autoimmune manifestations with hepatitis B has been less frequently reported than with hepatitis C virus. It is discussed whether this patient illustrates a case of spontaneous development of antimicrosomal antibodies, only casually associated with the pres...
