Background: Several adjuvants have been evaluated for vaccine formulations but alu-minum salts will continue to be used for many years due to their safety, low cost and adjuvanticity with different antigens. Two commonly used aluminum adjuvants, alumi-num hydroxide and aluminum phosphate have different adjuvanticity properties. Com-mercial recombinant protein hepatitis B vaccines containing alu...

BACKGROUND Knowledge of hepatitis B and C has been reported to be low among respondents in different studies. We conducted a cross-sectional study among international students of Universiti Putra Malaysia (UPM) to ascertain their levels of knowledge, attitude and practices regarding hepatitis B and C and its associated factors. METHODS Six hundred and sixty two (662) international students pa...

Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are the three most common chronic viral infections seen in the world. All three viruses share modes of transmission and hence co-exist in the same host at significantly high rates. HIV-induced immunosuppression has deleterious effects on the natural history, pathophysiology, diagnosis, therapeutic responses...

BACKGROUND AND PURPOSE Major hepatotropic viruses continue to be important causes of acute viral hepatitis in developing countries. This work was carried out to detect the seroprevalence of hepatitis E virus (HEV) markers in children with acute viral hepatitis due to hepatotropic viruses (A, B and C) and non-A, non-B, non-C acute hepatitis, and to ascertain the influence of HEV superinfection i...

Background Occult hepatitis B infection (OBI) is considered a risk factor for progression of liver disease in patients with hepatitis B virus (HBV) infection. This disease progression is reported to be more significant in those with concomitant HIV infection. We aimed to determine the prevalence rate of OBI in a sample of HIV-positive patients. Materials and Methods: Sixty-six HIV-infected pati...

Two antigen-antibody systems were Out of 42 sera from patients with acute viral hepatitis 33 were positive for HBsAg,all HBsAg positive individuals possessed anti-HBc. From 11 blood donors  sera 8 were positive for HBsAg and 9 were Positive for anti-HBc;2 leprosy sera were tested,both of them were positive for HBsAg and anti-HBc. 5 miscellaneous sam­ples,z·were positive for HBsAg and anti-HBc...

Background and Aims: Almost 350 million people worldwide are carriers of hepatitis B virus. The rate of chronic carriers in Iran is about 3%.  Therefore Iran is categorized as a country with moderate rate of infection with this virus. In developing countries, transmission from mother to fetus and newborn is considered as one of the main routes of transmission. So, this study investigated t...
