Use of human protein C concentrates in the treatment of patients with severe congenital protein C deficiency

Abstract

Sabine Kroiss, Manuela AlbisettiDivision of Hematology, University Children’s Hospital, Zurich, SwitzerlandAbstract: Protein C is one of the major inhibitors of the coagulation system that downregulate thrombin generation. Severe congenital protein C deficiency leads to a hypercoagulability state that usually presents at birth with purpura fulminans and/or severe venous and arterial thrombosis. Recurrent thrombotic events are commonly seen. From the 1990’s, several virus-inactivated human protein C concentrates have been developed. These concentrates currently constitute the therapy of choice for the treatment and prevention of clinical manifestations of severe congenital protein C deficiency. This review summarizes the available information on the use of human protein C concentrates in patients with severe congenital protein C deficiency.Keywords: Congenital protein C deficiency, protein C concentrate, purpura fulminans
