Previous studies have revealed antibody to hepatitis B core antigen (anti-HBc) levels as a predictor of treatment response in hepatitis B early antigen (HBeAg)-positive chronic hepatitis B (CHB) patients in both interferon and nucleos(t)ide analog therapy cohorts. However, there is no information about anti-HBc levels in the natural history of CHB. This study aimed to define anti-HBc levels of ...
The relationship between the presence of antibody to hepatitis B core antigen (anti-HBc) in donor blood and the development of hepatitis in recipients of that blood was studied in 6293 blood donors and 481 recipients who were followed for 6 to 9 months after transfusion. Of 193 recipients of at least 1 unit of blood positive for anti-HBc, 23 (11.9%) developed non-A, non-B hepatitis compared wit...
The purpose of the present study was to measure the amount of antibody to hepatitis B core antigen (anti-HBc) in different populations by the immunoelectroosmophoresis method. High titers of anti-HBc, up to 1/4,096, were found in the acute stage of hepatitis B virus infections and in the chronic carrier state of hepatitis B surface antigen. In cases of acute hepatitis the anti-HBc titers gradua...
چکید ه سابقه و هدف بروز هپاتیت b پس از انتقال خون با غربالگری خون های اهدایی برای hbsag کاهش یافته ولی هنوز hbv مسـؤول بـروز تعـدادی مـوارد هپاتیت پس از انتقال خون در سراسر جهان است. برآورد و تخمین میزان anti-hbc و hbv dna مثبت در واحدهای خون های اهدایی جهت ارزیابی لزوم غربالگری اهداکنندگان خون از نظر anti-hbc مهم است. در این مطالعه واحدهای خون اهدایی که hbsag منفی بودند از نظر anti-hbc مور...
هدف: عفونت نهفته هپاتیت b یک فرم بالینی از بیماری هپاتیت b است که در آن فرد با وجود این که از نظر hbsag منفی است اما دارای hbv-dna در خون محیطی است. این فرم از بیماری مشکلات عدیده ای را در انتقال خون به وجود خواهد آورد. هدف از انجام این تحقیق بررسی وضعیت عفونت نهفته هپاتیت b در میان اهداکنندگان خون رفسنجان است. مواد و روش ها: در این مطالعه مقطعی توصیفی تعداد 3700 نمونه پلاسما از انتقال خون رفسن...
occult hbv infection of hemodialysis (hd) patients is informative in terms of virus transmission. it may be of clinical importance in hd patients. the aim of this study was to investigate the prevalence of anti-hbc in the hd patients. number of 126 patients undergoing hemodialysis were included in this study from main hemodialysis units in yazd. hepatitis b surface antigens (hbsag), hepatitis b...
Furnas dos Dionísios is an Afro-Brazilian black community whose descendants were mainly fugitive slaves that established themselves in the State of Mato Grosso do Sul (MS), Brazil. The population is comprised mainly of low socioeconomic individuals who are engaged in agricultural activities. The objective of this study was to investigate the prevalence of hepatitis B (HB) and its correlation wi...
Introduction: In recent years with introduction of better screening tests, the risk of infection with transfusion-transmitted viruses has been reduced remarkably, although obtaining a zero-risk blood supply still remains international blood transfusion services goal. The routine test for detection of HBV infected blood samples is examination of HBsAg with ELISA method but in occult HBV infectio...
OBJECTIVE Testing for antibodies against hepatitis B core antigen (anti-HBc) was introduced to detect blood donors suffering from occult hepatitis B infection. Confirmation of specification of reactive results in the anti-HBc screening assay is still a challenge for blood donation services. METHODS Two different test strategies for confirmation of specification of reactive anti-HBc tests, one...
Occult HBV infection of hemodialysis (HD) patients is informative in terms of virus transmission. It may be of clinical importance in HD patients. The aim of this study was to investigate the prevalence of anti-HBc in the HD Patients. Number of 126 patients undergoing hemodialysis were included in this study from main hemodialysis units in Yazd. Hepatitis B surface antigens (HBsAg), hepatitis B...
