Hepatitis B antigen (HB Ag) detectable only by means of rvdioimmnnoassay was found in saliva of 5 out of 36 mentally retarded children in an institution. Electron microscopic study of purified antigen in saliva revealed the presence of tubular and small Dane particles.

Clinical performance of a new hepatitis B surface antigen quantitative assay with automatic dilution
Hepatitis B virus surface antigen (HBsAg) levels reflect disease status and can predict the clinical response to antiviral treatment; however, the emergence of HBsAg mutant strains has become a challenge.

Objectives: We sought to assess the prevalence of hepatitis B virus (HBV) seroprotection among vaccinated children in the Assiut governorate, Egypt, and assess a booster dose immune memory response among non-seroprotected children.

The predictive effect of quantitative anti-hepatitis B core on double-negative HBV DNA and RNA remains unstudied. We observed dynamic changes in this measure in chronic hepatitis B patients receiving entecavir for 10 years, evaluating its predictive ...

Hepatitis B antigen, hepatitis B antibody, and subtypes in leprosy [PDF]
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 ...

Background Hepatitis B e antigen (HBeAg) seroconversion represents an endpoint of treatment of chronic hepatitis B virus (HBV) infections. Methods We have studied whether levels of serum hepatitis B virus ribonucleic acid (HBV RNA) during pegylated ...

Hepatitis B e antigen-negative chronic hepatitis B [PDF]
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 ...

Current diagnosis of occult or cryptic hepatitis B [PDF]
The present article presents a kind of hepatitis B in patients whodo not have the surface antigen (HbsAg) detectable in sera. It hasbeen described in different parts of the world and is known todayas “occult or criptic hepatitis B” and its importance has

Background: Scientists perceive drug users (DUs) as a high-risk population for hepatitis B virus (HBV) infection. Effective strategies aiming at the reduction of HBV infection can be depicted when its epidemiological status is clearly defined.

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 ...
