The Korean Journal of Gastroenterology, 2021 Background/Aims: The HBsAg levels have been used to monitor the chronic hepatitis B (CHB) treatment response to antiviral therapy. On the other hand, it is unclear if the HBsAg quantification levels at each treatment point differ according to the HBeAg ...

Linearized hepatitis B surface antigen and hepatitis B core-related antigen in the natural history of chronic hepatitis B [PDF]
Clinical Microbiology and Infection, 2014 Changes in two novel HBV serological markers, linearized hepatitis B surface antigen (HQ-HBsAg) and hepatitis B core-related antigen (HBcrAg), in the natural history of chronic hepatitis B (CHB) have not been well characterized. Serum HQ-HBsAg and HBcrAg levels of 404 Asian treatment-naïve CHB patients were analysed in a cross-sectional manner ...

Hepatitis B antigen, hepatitis B antibody, and subtypes in leprosy [PDF]
Infection and Immunity, 1977 The prevalence of hepatitis B antigen (HBsAg), hepatitis B antibody (HBsAb), and subtypes in 242 cases of leprosy is reported. Patients were divided into three subgroups, lepromatous (174), tuberculoid (55), and borderline (13). A total of 131 patients were tested on admission; the remaining 111 had been institutionalized for a period of 3 months or ...

Monoclonal Antibodies Specific for Hepatitis B e Antigen and Hepatitis B Core Antigen
Hybridoma, 2011 Despite effective vaccination programs in many countries, HBV infection is still a serious health problem throughout the world; more than 2 billion people have been infected with Hepatitis B virus (HBV). The serologic markers are crucial indicators in clinical diagnosis of HBV infection. The persistent presence of anti-HBc is associated with chronicity,

Hepatitis B e antigen-negative chronic hepatitis B [PDF]
Hepatology, 2001 Summary HBeAg-negative CHB has now a worldwide distribution, developing in the course of HBeAg-positive chronic HBV infection during or after the phase of HBeAg loss and its seroconversion to anti-HBe. It is caused by replicating noncytopathic HBV mutants either unable to produce HBeAg (precore mutants) or with down-regulated transcription of the ...

Comparative immunogenicity of hepatitis B virus core and E antigens.
Journal of Immunology, 1988 The nucleocapsid (hepatitis B core Ag (HBcAg] of the hepatitis B virus is a particulate Ag composed of a single polypeptide (p21). Although a non-particulate form of HBcAg designated hepatitis B e Ag (HBeAg) shares significant amino acid identity, the ...
