Detection of HBV DNA in Cerumen and Sera of Hbsag Negative Patients with Chronic Hepatitis B Infection

Dear Editor, Chronic carriers of hepatitis infection are living throughout the world mostly in the South East of Asia. Recent studies have shown that some HBsAg negative individuals may develop some sort of chronic hepatitis B which is detectable employing some new laboratory diagnosis techniques such as molecular tests. In human during decades, HBV had many mutations by which this virus has be...

The Study of Cerumen Hepatitis B Infection in Chronic Hepatitis B Patients by Real-Time PCR

Introduction: The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including se...

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...

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...

Virus Infection by DNA Microarray Method from Patients with Chronic Hepatitis B Detection of Hepatitis B Virus DNA in Sera

Indication of Anti-HBc Antibody Screening and HBV-DNA Detection in Diagnosing Latent Hepatitis B Virus Infection

Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
