Reverse seroconversion of hepatitis B in a haemodialysis patient

Abstract
The appearance of hepatitis B surface antibodies (anti-HBs) and hepatitis B core antibodies (anti-HBc) is considered as serological evidence of resolved infection with clearance of the hepatitis B virus (HBV). Viral reactivation in this situation (reverse seroconversion) is a rare, but well described complication in transplanted patients receiving immunosuppressive therapy [1,2], in patients subjected to cytotoxic chemotherapy [2,3], or in HIV infected individuals [2,4].
