Growing attention to an old marker, hepatitis B surface antigen, in the natural history of chronic hepatitis B Serum hepatitis B surface antigen and hepatitis B e antigen titers: disease phase influences correlation with viral load and intrahepatic hepatitis B virus markers. Hepatitis B surface antigen (HBsAg), originally referred as to " Australia antigen " was discovered approximately 40 year...

An approach has been developed for the analysis of hepatitis B viral (HBV) antigenic structure that creates numerical "signatures" of HBV strains. This technique employs high-affinity IgM and IgG monoclonal antibodies (anti-HBsAg) directed toward distinct and separate determinants on hepatitis B surface antigen (HBsAg). Such antibodies have been used to develop sensitive and specific radioimmun...

Diagnosis of hepatitis B is routinely based on of serological assay of hepatitis B surface antigen (HBsAg). Occult hepatitis B virus (HBV) infection is generally defined as the detection of HBV -DNA in the serum or tissues of subjects who have negative test for HBsAg. Transmission of HBV infection has been documented from HBsAg negative, anti-HBc positive blood and organ donors. The aim of this...

Hepatitis B virus (HBV) surface antigen (HBsAg) is one of the most important serological markers of current HBV infection. However, there are significant antigenic variations of HBsAg caused by genotypic diversity as well as mutation of the HBV genome. It is predictable that amino acid substitutions occurring in the HBsAg "a" determinant of a particular HBV genotype will affect the sensitivity ...

BACKGROUND Pregnant women with Hepatitis B virus HBV represent a major reservoir of the virus in the community. Data regarding the prevalence of HBV in pregnant women and maternal transmission of the virus in Libya are lacking. METHODOLOGY Hepatitis blood samples from 1,500 pregnant women and 1,500 cord blood samples of their neonates delivered at Tripoli Medical Center, Tripoli, were tested ...

A cross-sectional analysis of prevalence of hepatitis B virus infection (HBV) among rural couples was conducted between 2010 and 2014. Serologic HBV markers, including hepatitis B surface antigen (HBsAg) and e antigen (HBeAg), were tested. Primary outcome of interest comprised HBsAg positivity in couples (both positive: F+M+, only wife positive: F+M-, only husband positive: F-M+), and secondary...

BACKGROUND & AIMS About 350-400 million people are infected with hepatitis B virus (HBV) chronically and 1 million people die of hepatitis B virus (HBV)-related liver diseases. Nucleos(t)ide analogues (NAs) have been used for the treatment against HBV. However, few studies have investigated the long-term effects of different nucleos(t)ide analogues on levels of hepatitis B surface antigen (HBsA...

BACKGROUND Kinetics of serum hepatitis B surface antigen (HBsAg) level in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B patients presented with severe reactivation and received oral antiviral therapy is unknown. We aimed to investigate the kinetics of HBsAg level among these patients. METHODS HBeAg-negative patients on antiviral therapy with follow-up for 2 years were studied. Th...

BACKGROUND Interferon alpha (IFNα) therapy has been widely used in the treatment of chronic hepatitis B (CHB) for decades. Nucleos(t)ide analogues are also increasingly used to treat CHB recently. More and more studies are being carried out concerning the clearance or seroconversion of HBsAg, which is recognized as an ideal goal of CHB therapy. This study conducted a meta-analysis to estimate t...
