A fully automated chemiluminescent microparticle immunoassay (Architect HBsAg QT) was used for the detection and quantitation of hepatitis B surface antigen (HBsAg). The assay is capable of processing up to 800 HBsAg tests per hour. The concentration of HBsAg is determined by utilizing a previously generated Architect HBsAg calibration curve. Architect HBsAg QT sensitivity was found to be aroun...
خلاصهسابقه و هدف: براساس برآورد سازمان جهانی بهداشت در حدود 350 میلیون نفر از جمعیت جهان به ویروس هپاتیت b آلوده هستند و سالانه در حدود 2 میلیون نفر از عوارض هپاتیت b، جان خود را از دست می دهند. هدف این تحقیق، تعیین فراوانی موارد مثبت hbsag در سرم زنان باردار مراجعه کننده به زایشگاه نیک نفس شهر رفسنجان سال 1382 بوده است.مواد و روش ها: این مطالعه یک مطالعه توصیفی مقطعی درسال 1382 می باشد، که تعد...
BACKGROUND The prevalence of hepatitis B virus infection in Greece has been decreasing over the last decades. However, recent epidemiological data are lacking. METHODS We studied 1,840 Army recruits from 05/2004 until 10/2005, and performed serological testing for HBsAg, anti-HBsAg, and anti-HBcAg. We also examined their association with several factors, including age, residential area, socio...
BACKGROUND The aim of this study was to characterize the expression and secretion of hepatitis B surface-antigen (HBsAg) in the hepatocytes of hepatitis B virus (HBV)-infected patients at different phases of infection; as such, the association of intrahepatic HBsAg expression with virological markers and the histological characteristics were analyzed. MATERIAL AND METHODS 302 chronic HBV infect...
BACKGROUND In this study, we aimed to identify baseline predictors of response in chronic hepatitis B patients treated with a combination of pegylated interferon (PEG-IFN)-α2a and adefovir. METHODS We treated 92 chronic hepatitis B patients (44 hepatitis B e antigen [HBeAg]-positive and 48 HBeAg-negative) with HBV DNA > 100,000 copies/ml (> 17,182 IU/ml) with PEG-IFN and adefovir for 48 weeks...
BACKGROUND Viral load measurement is necessary to estimate mother-to-child transmission risk for women with chronic hepatitis B (CHB), however, it is expensive. The present study aimed to investigate the relationship between HBsAg and hepatitis B virus (HBV) DNA levels, and to determine potential applications of HBsAg level monitoring for estimating viral load. METHODS 85 patients with CHB (3...
چکید ه سابقه و هدف سلامت خون و کاهش خطر انتقال بیماری‌های عفونی از جمله هپاتیت B در دوره پنجره از طریق خون از اهمیت به سزایی برخوردار است. جهت استفاده از خون و فرآورده‌های خونی سالم، یکی از گزینه‌هایی که بر آن تاکید شده است، جمع‌آوری خون‌های اهدایی سالم از بین اهداکنندگانی است که در معرض خطر کمتری هستند. مواد وروش‌ها مطالعه انجام شده از نوع توصیفی بود. 8468 فرم ثبت نام اهداکنندگانی که...
BACKGROUND The elimination of hepatitis B virus surface antigen (HBsAg) is the final goal of hepatitis B treatment, but is rarely achieved. As quantitative assays for HBsAg recently became available, we have investigated whether quantitative HBsAg measurements can substitute for hepatitis B virus (HBV) DNA quantification in treatment monitoring. METHODS Within this study, 23 liver transplant ...
BACKGROUND The decline in hepatitis B virus surface antigen (HBsAg) may be an early predictor of the viral efficacy of Hepatitis B virus (HBV) therapy. The HBsAg levels obtained by different immunoassays now need comparing and the relationships between levels of HBsAg and HBV DNA alongside HBsAg and genotype must be evaluated. METHODOLOGY/PRINCIPAL FINDINGS HBsAg levels were compared among 80...
BACKGROUND With use of peginterferon alfa-2a and ribavirin combination therapy in patients with dual chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, 11.2% of patients achieved clearance of hepatitis B surface antigen (HBsAg) at 6 months after treatment; however, reactivation of HBV DNA was observed in 36.3%. We investigated the predictive potential of HBsAg quantification...
