title: Post-transfusion purpura (PTP) and disseminated intravascular coagulation (DIC).
abstract: A 47-yr-old female with acute pancreatitis received four units of fresh frozen plasma because of subtle signs of disseminated intravascular coagulation (DIC). Seven days later, she developed severe thrombocytopenia. Serological studies demonstrated antibodies against HPA-1a together with pan-reactive antibodies against platelet glycoproteins (GPIIb-IIIa, GPIb-IX and GPIa-IIa), which was consistent with the diagnosis of PTP. The patient was treated with platelet transfusions, corticosteroids and intravenous immunoglobulin (IVIG) without permanent beneficial effect. After treatment with plasma exchange the platelet count increased to normal values.
