CHARACTERISTICS AND PREVALENCE OF OCCULT HEPATITIS B VIRUS INFECTION IN PATIENTS WITH HEPATITIS C IN IRAN
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...
متن کاملHepatitis B Virus Infection in Patients with Blood Disorders: A Concise Review in Pediatric Study
Childhood Hepatitis B virus (HBV) infection causes both medical and public health challenges. Infants who acquire HBV parentally have up to 90% risk of developing chronic HBV infection. It is now estimated that approximately 10% of worldwide cancers are attributable to viral infection, with the vast majority (>85 %) occurring in the developing world. In this distribution, elevated rate and prev...
متن کاملHEPATITIS B VIRUS INFECTION IN AN ANTI-HBC NEGATIVE PATIENT: A CASE REPORT
ABSTRACT One of the best reliable markers of hepatitis B virus infection is antibodies to the core antigen (Anti-HBc). A first-time blood donor with HBsAg positivity was identified as an HBV carrier that was anti-HBc negative. The patient was followed for 24 months in order to investigate the evolution of his HBV serological profiles and HBVDNA (PCR). In the follow-up for 24 months, HBsAg, HBe...
متن کاملOccult hepatitis B virus infection: implications in transfusion.
Hepatitis B virus (HBV) presents a higher residual risk of transmission by transfusion than hepatitis C virus (HCV) or human immunodeficiency virus (HIV). While most infectious blood units are removed by screening for hepatitis B surface antigen (HBsAg), there is clear evidence that transmission by HBsAg-negative components occurs, in part, during the serologically negative window period, but m...
متن کاملOccult Hepatitis B Virus Infection in Nigerian Blood Donors and Hepatitis B Virus Transmission Risks
BACKGROUND Occult hepatitis B virus infection (OBI) characterized by the absence of detectable HBsAg remains a potential threat in blood safety. We investigated the actual prevalence, viral factors and genotype of OBI infections in Nigerian blood donors. METHODS Serum collected from two blood banks were reconfirmed as HBsAg seronegative by ELISA. Forty HBsAg positive samples were employed as ...
