AIM To evaluate pretreatment hepatitis B virus (HBV) testing, vaccination, and antiviral treatment rates in Veterans Affairs patients receiving anti-CD20 Ab for quality improvement. METHODS We performed a retrospective cohort study using a national repository of Veterans Health Administration (VHA) electronic health record data. We identified all patients receiving anti-CD20 Ab treatment (200...

introduction: vaccination with the major surface antigen of hepatitis b virus (hbsag) induces anti-hbs antibody production and level of 10 iu/l is considered protective. it has been shown that the level of anti-hbs antibody does wane after vaccination. the aim of this study was to evaluate the persistence of anti-hbs antibodies in healthy iranian children 10 years after primary vaccination. met...

Eighty-four healthy graduate participants were administered the standard course of 3 hepatitis B vaccinations. Five months after the first dose (shortly after the second injection), each participant completed psychosocial measures, and a blood sample was drawn for determination of hepatitis B surface antibody titer. After completion of the vaccination series, participants performed an acute str...

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 & Aims: Hepatitis B virus is one of the causes of acute and chronic hepatitis. Due to multiple hospitalization and blood transfusion, thalassaemic patients are at higher risk of this infection. Duration of the immunity after vaccination in this high-risk group and the need for booster vaccination is uncertain. The aim of this study was to find antibody titration and immunity to Hepat...

background despite the advances in the treatment of chronic hepatitis b virus (hbv) infection, liver transplantation (lt) remains the only hope for many patients with end-stage liver diseases resulting from hbv. objectives the aim of this study was to investigate the rate of hbv recurrence in cases that had undergone lt due to the hbv related liver cirrhosis. patients and methods forty-nine pat...

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...

Hepatitis B virus (HBV) infection is highly endemic in Senegal. Vaccination of all children against HBV was introduced 1999 and included Expanded Programme on Immunisation 2005. The aim this study to assess the prevalence immune status patients received at Pasteur Institut Dakar, Methods: Between January 2016 December 2020, aged between 1 96 years laboratory were study. Serum samples analysed f...

The aim was to determine whether the immunogenicity of an investigational hepatitis B vaccine (spHB) is at least as high as that of a licensed control vaccine, Engerix B, and to evaluate its safety before inclusion in new pediatric combination vaccines. Two randomized, controlled, blind-observer, Phase 3 trials were performed: one in Argentina (344 participants aged 10-15 years, 10 microg HBsAg...
