Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the only m...
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...
Exclusion of liver grafts from hepatitis B core antibody (anti-HBc) positive donors to prevent de novo hepatitis B virus (HBV) infection after liver transplantation is not feasible in areas highly endemic for HBV virus like Taiwan, where approximately 80% of adults are anti-HBc(+). The efficacy of lamivudine monotherapy to prevent de novo HBV infection after living donor liver transplantation (...
Several studies have reported that antibody to hepatitis B core antigen (anti-HBc) positivity may influence the development of hepatocellular carcinoma (HCC) in chronic hepatitis C patients, but the evidence is still not conclusive. In this study, we examined whether the presence of anti-HBc positive was associated with the development of HCC in hepatitis C virus (HCV)-infected subjects among t...
Routine use of the automated chemiluminescent microparticle immunoassay Abbott ARCHITECT anti-HBc for diagnosis of hepatitis B is limited in case of borderline reactive sera with low signal close to the cut-off index. In order to determine the significance of anti-HBc detection when borderline reactivity occurs using the ARCHITECT anti-HBc assay, a comparative study was designed. 3540 serum sam...
Objective: During viral hepatitis B, serum HBsAg and HBeAg were important indexes reflecting viral replication and liver inflammation. However, patients with negative serum HBeAg still developed viremia or inflammatory necrosis. Negative HBsAg patients also had serum HBV DNA. This study thus analysed patients who were negative for HABsAg or HBeAg, to provide evidences for diagnosing chronic hep...
Four-hundred and seventeen patients undergoing open-heart surgery were followed for more than 9 months after transfusion. All 2270 blood units transfused had alanine aminotransferase levels less than or equal to 30 U/l. Blood units positive for antibodies to hepatitis B core antigen (anti-HBc) were more frequently associated with recipient hepatitis non-A, non-B (HNANB) (13.7%) than anti-HBc-ne...
چکید ه سابقه و هدف رایج ترین مارکر مورد استفاده جهت تشخیص عفونت hbv در اهداکنندگان خون، غربالگری hbsag است که عدم شناسایی آن، به عللی مانند دوره پنجره، موتاسیون در ژن s و یا کاهش ساخت این ag ، ممکن است در گیرندگان این فرآورده ها ایجاد بیماری نماید. از آن جایی که شیوع anti-hbc در جمعیت ها با شیوع hbsag متناسب است، بنابراین لازم است در مناطقی با شیوع بالای hbv ، مطالعه هایی در زمینه ارزیابی ش...
Non invasive immunologic markers of virus-induced liver disease are unmet needs. We tested the clinical significance of quantitative total and IgM-anti-HBc in well characterized chronic-HBsAg-carriers. Sera (212) were obtained from 111 HBsAg-carriers followed-up for 52 months (28-216) during different phases of chronic-HBV-genotype-D-infection: 10 HBeAg-positive, 25 inactive-carriers (HBV-DNA≤2...
Studies regarding the clinical significance of quantitative hepatitis B core antibody (anti-HBc) in patients with chronic hepatitis B receiving first-line nucleos(t)ide analogues is limited. The aim of this study was to determine the performance of anti-HBc as a predictor for hepatitis B e antigen (HBeAg) seroconversion in HBeAg-positive CHB patients treated with entecavir. This was a retrospec...
