Screening with hepatitis B surface antigen (HBsAg) is highly recommended for at-risk individuals. Mutations in the HBsAg can result in an inability to detect the virus during routine screening. We describe a hemodialysis patient found to have high levels of hepatitis B virus (HBV) DNA and HBV antibody but negative HBsAg on two routine assays.

results the mean age of children was 6.5 ± 4.2 years. the frequency of positive results for hbsag, anti-hbs and anti-hcv in all age groups were 12 (3.6%), 47 (14.2%) and 2 (0.6%), respectively. anti-hiv was not detected in any of the children's serum samples. the frequency of positive results for hbsag was significantly higher in children older than six years than in other age groups. conclusio...

BACKGROUND The risk of anti-tuberculosis (TB) drug-induced liver injury (DILI) in patients with chronic viral hepatitis (CVH) is not clear. The aim of this study was to investigate incidence and risk factors associated with TB DILI in CVH and non-CVH patients. METHODS Retrospectively, a total of 128 CVH patients who received anti-TB medication from January 2005 to February 2014 were reviewed....

A boy was born to a mother who was a chronic hepatitis B virus (HBV) carrier. She was hepatitis Be (HBe) antibody positive and HBe antigen and HBV-DNA negative. The boy had not received hepatitis B vaccine and died from fulminant hepatitis at 3 months of age. This case demonstrates the need to vaccinate babies of HBe antibody positive, HBe antigen negative carriers.

Studies on the prevalence of infection with hepatitis B virus (HBV) among children are scarce in Latin American countries, especially in Mexico. This study was aimed to investigate the prevalence of HBV infection, occult hepatitis B infection (OBI) and HBV genotypes among children with clinical hepatitis. In total, 215 children with clinical hepatitis were evaluated for HBV infection. HBV serol...

This is the first paper in which it was stated that Australia antigen (Au) was the hepatitis virus. This subsequently led to the identification of the hepatitis B virus (HBV), the development of methods for the diagnosis of hepatitis B, the prevention of post-transfusion hepatitis, the control of hepatitis in high risk environments, a vaccine against hepatitis B, and the recognition of the role...

    Background: Hepatitis B Virus (HBV) causes acute and chronic liver disease worldwide. HBV has eight genotypes (A to H) which is the reflection of its genome with their characteristic geographical distribution. Each genotype could have different pathogenic and therapeutic characteristics. There have been few records on HBV genotyping in general population from our region. This study aimed to...

background: blood transfusion plays a great role in public health and the blood safety still has remained a main concern. hbv has been considered as one of the most prevalent blood borne infections. it is estimated that chronic hbv affects 350-400 million people worldwide. comprehensive knowledge about hbv has high importance in iran due to high number of blood dependent patients. material and ...

Globally, WHO estimates that 350 million individuals are infected with HBV and that HBV is endemic in sub-Saharan Africa and regions of Asia. Hepatitis B is a major risk factor for hepatocellular carcinoma. Hepatitis B is treated with oral nucleoside reverse transcriptase inhibitors. Bolognese J.
