[Graft versus host reaction in an infant with DiGeorge syndrome]

An infant with complete DiGeorge syndrome was treated with blood transfusions and fresh frozen plasma because of severe septicemia and anemia. 9 weeks after the first transfusion and 2 weeks after administration of fresh frozen plasma he died of acute graft-versus-host disease. The blood products were routinely irradiated with 25 gray, the fresh frozen plasma was not irradiated. The diagnosis of GvHD was confirmed on autopsy. All cellular blood products including fresh frozen plasma which are used in the treatment of immuno-deficient patients have to be irradiated to avoid GvHD. Currently 50 gray are recommended.
