Correlation between HBsAg quantitative assay results and HBV DNA levels in chronic HBV

BACKGROUND Viral load has been used to diagnose and monitor patients who are being treated for chronic hepatitis B (CHB). The Diagnosis methods are molecular-based and expensive. Quantitation of hepatitis B surface antigen (HBsAg) by automated chemiluminescent micro-particle immunoassay has been proposed to be a surrogate marker. Quantitating HBV DNA levels molecularly is expensive; thus, a che...

The Relationship between HBSAG and HBV DNA in HBV-Infected Blood Donors

Association between HBe-Ag and HBV-DNA level in HBsAg positive chronic carriers

Background: Viral hepatitis is one of common infectious diseases and known as health problem around the world. Present cross-sectional study was performed to determine the association between HBeAg and HBV-DNA in patients who referred to Royan Institute for Reproductive Biomedicine and Amiralmomenin Hospital (Islamic Azad University) between 2012 and 2015. Materials and methods: In this cross-s...

Relationship between HBV DNA load and levels of serum HBsAg in patients with chronic hepatitis B.

OBJECTIVE This study aims to investigate the relationship between HBV DNA load and levels of serum HBsAg in patients with chronic hepatitis B (CHB). PATIENTS AND METHODS Between April 20013 and July 2015, serum samples were collected from 124 CHB patients. Levels of serum HBsAg was determined using chemiluminescent immunoassay and HBV DNA load was measured using quantitative fluorescent RT-PC...

بررسی غلظت بتا دومیکروگلوبولین سرمی درافراد HBV DNA PCR+، HBsAg+و-HBV DNA PCR ، HBsAg+: به عنوان نشانگر تکثیر ویروس

  چکید ه   سابقه و هدف   ‌بتادومیکروگلوبولین ( b 2MG) ، زنجیره سبک آنتی‌ژن MHC-I می‌باشد که غلظت سرمی آن ( S β 2MG ) در افراد سالم کمتر از mg/L 3 ذکر شده است. در عفونت‌های هپاتیتی، عرضه آنتی‌ژن‌های ویروسی سطح هپاتوسیت‌ها روی آنتی‌ژن‌های MHC-I در حذف ویروس نقش مهمی ایفا می‌کند.   مواد و روش‌ها   در این مطالعه توصیفی درسرم 4 9 بیمار مبتلا به هپاتیت B در مقایسه با 3 5 فرد کنترل با سرولوژی منفی (فا...

Detection of HBV DNA in HBsAg Negative Normal Blood Donors

Background: The risk of infection by transfusion-transmitted viruses has been reduced remarkably. However, a zero-risk blood supply is still desirable. The screening for antibody to HBc (anti-HBc) has been shown as an alternative test for the detection of HBV infection. Objective: The main aim of this study was to evaluate HBV infection markers and the potential value of anti-HBc testing of blo...
