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 ...
متن کاملHepatitis B virus reactivation after effective sofosbuvir and ribavirin treatment in a patient with occult hepatitis B virus infection.
Reactivation of the hepatitis B virus (HBV) has been reported in patients with occult infection (OBI), i.e. HBV surface antigen (HBsAg) negative, HBV core antibody (anti-HBc) positive ± antibodies against HBsAg (anti-HBs) and detectable HBV DNA in serum or liver, receiving immunosuppressive or cytotoxic therapies. Recently, concerns have been raised regarding the risk of HBV reactivation in OBI...
