background and aims: many studies have provided evidence for the role of hepatitis b and c viruses in the development of liver cancer. although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with hbv and hcv. this study was performed to determine the frequency of hbv/hcv-coinfection in mashhad, north-east of iran. mat...

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...

In Gabon, a central African country, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are endemic. In a recent study, conducted in a semi-urban area (Franceville, Gabon), HBV infection was found to be more prevalent among HIV infected individuals. This study aims to investigate the prevalence and genetic diversity of hepatitis B virus infection among HIV infected individuals, pred...

Background and Aims: Occult hepatitis B virus infection (OBI) is known as an important source of hepatitis B virus (HBV) infection. It is categorized as Hepatitis B surface antigen (HBsAg) not being present and low DNA viral load in serum. In this study, an attempt was made to investigate the outbreak of anti-HBc and OBI among the HBsAg-negative donors in Golestan province. Materials and Metho...

occult hbv infection of hemodialysis (hd) patients is informative in terms of virus transmission. it may be of clinical importance in hd patients. the aim of this study was to investigate the prevalence of anti-hbc in the hd patients. number of 126 patients undergoing hemodialysis were included in this study from main hemodialysis units in yazd. hepatitis b surface antigens (hbsag), hepatitis b...

Woodchuck hepatitis virus (WHV) is molecularly and pathogenically closely related to hepatitis B virus (HBV). Both viruses display tropism towards hepatocytes and cells of the immune system and cause similar liver pathology, where acute hepatitis can progress to chronic hepatitis and to hepatocellular carcinoma (HCC). Two forms of occult hepadnaviral persistence were identified in the woodchuck...

PURPOSE The purpose of this study was to explore the outcomes and risk factors for hepatitis B virus (HBV) reactivation after kidney transplantation in occult HBV carriers, who are hepatitis B surface antigen (HBsAg) seronegative and hepatitis B core antibody (HBcAb) seropositive before kidney transplantation. METHODS We retrospectively analyzed 322 occult HBV carriers who received kidney tra...
