title: Intravenous or intramuscular anti-HBs immunoglobulin for the prevention of hepatitis B reinfection after orthotopic liver transplantation.
abstract: To prevent reinfection with hepatitis B virus after orthotopic liver transplantation, patients receive long-term intravenous anti-HBs immunoprophylaxis. We compared the pharmacokinetics of intravenously and intramuscularly administered commercially available hepatitis B virus immunoglobulins. The study group consisted of 12 patients on immunoprophylaxis after orthotopic liver transplantation, who were Hbs antigen negative; 11 were anti-HBe positive and one was HBe positive. The patients first received intravenous immunoglobulin, and six of them were then transferred to intramuscular immunoglobulin. Our findings show that with fortnightly intramuscular application of 1000 IU of anti-HBs, reproducible and stable antibody titers above 100 IU of anti-HBs can be achieved. Side effects of intramuscular immunoprophylaxis are minimal and the method is safe. The switch from intravenous (1500 IU of anti-HBs) to intramuscular (1000 IU of anti-HBs) reduced the cost of immunoprophylaxis by more than 50%.
