title: [Hepatitis B immunization of patients with inherited bleeding disorders: personal experiences].
abstract: Hepatitis B immunization of patients with inherited bleeding disorders: personal experiences Hepatitis B vaccination was initiated in 55 patients with inherited bleeding disorders in 1994-2009. Patients received three doses of subcutaneous recombinant vaccine containing 20 mg HBsAg (hepatitis B surface antigen) at 0, 1 and 6 months. Blood samples were obtained at the starting of vaccination, 1-3 months after immunization, and biennially thereafter. The samples were tested for HBsAg, hepatitis B surface and core antibodies (anti-HBs, anti-HBc). Protective anti-HBs level (≥10 IU/l) after immunization was proved in 50 of 51 patients (98 %). Waning of protective anti-HBs antibodies was detected in 4 % and 24 % of patients within 5 and 10 years after vaccination. No HBsAg carrier status or anti-HBc seroconversion were detected. Subcutaneous vaccination against hepatitis B provides long-term protection in patients with inherited bleeding disorders.
