<b><i>Background:</i></b> Chronicity or seroclearance of hepatitis B virus (HBV) antigens is determined by the host immune responses. Current approaches to treat HBV patients are based on inhibition replication using different antivirals (nucleoside nucleotide analogs) as monotherapy, along with modulators combination therapy being used worldwide for reducing viral load....

The worldwide seroprevalence of hepatitis A virus (HAV) and hepatitis B virus (HBV) has changed over the last two decades, indicating a declining incidence of HAV and HBV infections. Therefore, vaccinations against HAV and HBV are recommended for unimmunized people before traveling to an endemic area. Unfortunately, primary antibody deficiency (PAD) patients can only obtain humoral immunity thr...

Acute hepatitis B virus (HBV) infection is typically distinguished from chronic disease by a positive IgM anti-hepatitis B core antigen (anti-HBc) test. Patients with chronic hepatitis B remain hepatitis B surface antigen (HBsAg) positive, often with raised serum alanine aminotransferase (ALT) activities, for more than six months. The presence of hepatitis B e antigen (HBeAg) and HBV-DNA correl...

The prevention of hepatitis B by vaccination is one of the most efficient tools to avoid the transmission of the virus. This study evaluated the immunogenicity of the national vaccine Butang in children born in Campo Mourão City, state of Paraná, Brazil, aged 7 to 12 months, by determining the anti-HBsAg antibodies levels after completion of the National Immunization Program Protocol for hepati...

OBJECTIVES Protective vaccinations are the most effective method of prevention of type B virus hepatitis. The aim of the study was to determine whether in children receiving immunosuppressive therapy due to inflammatory systemic connective tissue diseases the protective concentration of the anti-HBs antibodies produced after vaccination against type B virus hepatitis in infancy is maintained. ...

Human Immunodeficiency Virus (HIV),Hepatitis B virus (HBV) and C virus (HCV) are known to be transmitted through blood and blood products. Many studies have been performed to determine relationship between infectious diseases and blood groups. This study aims to detect the relationship between the HIV, HBV and HCV infections with ABO and Rh D blood groups in Haryana. After blood donation, blood...

In order to develop an experimental DNA vaccine for the prevention and treatment of hepatitis B virus infection, hepatitis B virus surface antigen (HBsAg) DNA was subcloned into an E. coli-eukaryotic cell shuttle vector and was expressed in the Baculovirus expression system. Intramuscular, intradermal, and intraperitoneal injections of 30 microg of the plasmid DNA expressing HBsAg induced humor...

Introduction: Intravenous drug users as a serious health problem in communities have economical and social effects as well as health and hygienic complications. Viral infections may be transmitted through drug injection by shared syringes among users. The aim of this study has been to determine the relative frequency of HBV, HCV and HIV infection’s markers as epidemiological data in Ahvaz. Ma...

BACKGROUND Sub-Saharan Africa has a high prevalence of hepatitis B virus (HBV) infections. Health care workers (HCWs) are at high risk of contracting HBV infection through their occupation. Vaccination of HCWs against HBV is standard practice in many countries, but is often not implemented in resource-poor settings. We aimed with this cross-sectional study to determine HBV prevalence, HCW vacci...
