BACKGROUND AND AIM: Hepatitis B Virus (HBV), a DNA virus with a human-only reservoir, is a worldwide public health problem. Approximately 45.0% of the world’s population is considered to live in areas of high endemicity with a lifetime risk of infection of more than 60.0%. The present study aimed to assess the level of understanding and awareness about Hepatitis B immunization among the first a...

BACKGROUND AND OBJECTIVE The aim of this study was to investigate the prevalence of occult hepatitis B virus (HBV) infection and the HBV surface (S) gene variants circulating in the South African population after nearly two decades of universal hepatitis B vaccination. STUDY DESIGN From a previous serosurvey, 201 serum samples with serological evidence of exposure to HBV were identified and t...

background: recently, some new viruses have been identified for their association with hepatitis which torque teno mini virus being among them. the aim of this study was to determine the frequency of torque teno mini virus in healthy individuals and hepatitis b and c patients in isfahan, iran. materials and methods: one hundred serum samples of healthy individuals from isfahan blood transfusion...

Anti-HBc positivity is a frequent cause of donation rejection at blood banks. Hepatitis B virus (HBV) infection may also occur in HBsAg-negative patients, a situation denoted occult infection. Similarly, very low levels of HBV-DNA have also been found in the sera of patients with chronic hepatitis C virus (HCV) infection, even in the absence of serum HBsAg. Initially we searched for HBV-DNA in ...

Reactivation of Hepatitis B virus causing liver damage is a concern in patients with chronic HBV infections who receive immunosuppressive or cytotoxic treatments. HBV screening should be considered for all patients going to receive immunosuppressive regimens which have the potential to induce reactivation of HBV infection. We discuss here a case of occult Hepatitis B flare after chemotherapy in...

Occult hepatitis B virus infection (HBV) is characterized by HBV DNA positivity but HBV surface antigen (HBsAg) negativity. Occult HBV infection is associated with a risk of HBV transmission through blood transfusion, hemodialysis, and liver transplantation. Furthermore, occult HBV infection contributes to the development of cirrhosis and hepatocellular carcinoma. We recently reported the chara...
