28 of 1002 pregnant Sicilian women (2.8%) were asymptomatic HBsAg chronic carriers. 18 children of these women were followed and at least 15 of them showed evidence of transplacental infection with HBsAg, resulting either from the presence of the antigen in cord blood, or from the development of the corresponding antibody in the serum within the first 2 months of life. Despite this, only 2 or 3...

Background: Hemodialysis (HD) patients are at an increased risk of acquiring the hepatitis B (HB) virus and having lower protective antibody levels as well as shorter durations of seroprotection. This study aims to determine the immune response of HB vaccination in HD patients referring to dialysis centers of the Tehran North Health Network. Materials and Methods: This descriptive study was co...

The survey was carried out to determine the molecular detection of Hepatitis B virus markers among blood donors between age 18-65 years from National Blood Transfusion Service (NBTS) centre in Kaduna, Nigeria. samples were screened for (HBV) using Diagnostic kit HBV infection marker whole blood. serological determined polymerase chain reaction and confirmed. socio-demographic factors associated...

This study describes a new strategy toward the development of advanced immunosensors based on chemically functionalized magnetic-core/porous-shell CoFe2O4/Cu2O composite nanoparticles, and the preparation, characterization, and measurement of relevant properties of the immunosensor useful for the detection of hepatitis B surface antigen (HBsAg) in clinical immunoassay. The immunosensor based on...

Efficacy of low-dose, intra-dermal hepatitis B vaccination was assessed among sixty-one doctors and paramedical staff of Chandka Medical College Hospital, Larkana. Subjects were randomly divided into two groups. Group-A (n = 25) received 20 micrograms of purified Hepatitis B Surface Antigen (Euvax B, LG Chemicals) by i.m. injection in the deltoid by 0, 1 and 6 schedule while group B (n = 36) re...

background: hepatitis b infection is a major public health problem worldwide. given that immune response towards the vaccine is not perfect, we aimed to evaluate circumstances of immune response in vaccinated students. materials and methods: in this study, 219 medical students of ardabil university of medical sciences were recruited, who had been administered vaccine series for the first time, ...

background: conventional hepatitis b virus (hbv) vaccination fails to achieve efficient protection in about 5–10% of the world population. hence, different strategies have been adopted to ameliorate hbv antibody titers. this study aimed to evaluate the concurrent application of tetanus‑diphtheria (td) and hbv vaccination on hepatitis b surface (hbs) antibody titer in low‑responder healthy indiv...
