Role of Hepatitis B Virus Surface Antigen Quantification in E Antigen Negative Chronic Hepatitis B Infection
نویسندگان
چکیده
Background/Aim: Hepatitis B surface antigen(HBsAg) is routinely detected qualitatively in Hepatitis B Virus(HBV) infection where its persistence beyond 6 months defines chronic hepatitis B(CHB) infection. Hepatitis B e antigen (HBeAg) usually indicates active HBV replication and risk of transmission of infection. In spite of the emerging use of chemiluminescence based quantitative HBsAg assays for therapeutic monitoring of the patients, we measured HBsAg concentration by sandwich ELISA as a cost effective alternative to ascertain the role of HBsAg levels as surrogate marker of untreated HBeAg negative subjects having CHB infection.

ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

Abstract Background: Naturally occurred hepatitis B virus (HBV) with surface mutations in a variety of chronic hepatitis B (CHB) patients who have received no vaccine or HBIG bearing substitutions in surface protein, have been reported. Objectives: Current knowledge concerning the prevalence of these naturally occurring surface antigen mutations among Iranian carriers is limited. Patients and M...
متن کاملPrevalence of Hepatitis B Surface Antigen and Associated Risk Factors with Hepatitis B Infection among Pregnant Women in Northeast of Iran
Background and Aims: Almost 350 million people worldwide are carriers of hepatitis B virus. The rate of chronic carriers in Iran is about 3%. Therefore Iran is categorized as a country with moderate rate of infection with this virus. In developing countries, transmission from mother to fetus and newborn is considered as one of the main routes of transmission. So, this study investigated t...

Abstract Background and objectives: Hepatitis B virus infection is a major health problem in worldwide. The prevalence of Occult and chronic HBV in hemodialysis patients is higher than standard in developing countries. People with occult HBV are negative for HBV surface antigen (HBsAg) but positive for HBV-DNA. We aimed to evaluate occult hepatitis B infection in patients under hemodialysis in ...
متن کاملPriming Hepatitis B Surface (HBsAg)- and Core Antigen (HBcAg)-Specific Immune Responses by Chimeric, HBcAg with a HBsAg ‘a’ Determinant
We developed an immunogen to stimulate multivalent immunity against hepatitis B surface antigen (HBsAg) and hepatitis B core antigens (HBcAg). Immune responses specific for both HBsAg and HBcAg play an important role in controlling the infection. HBsAg-specific antibodies mediate elimination of virions at an early stage of infection and prevent the spread of virus. The immunogen was constructed...
