Protein C Infusion Therapy in an Adult Case of Severe Congenital Protein C Deficiency

Background:Severe congenital protein C deficiency (SCPCD) is a rare inherited disorder characterized by recurrent thrombosis, disseminated intravascular coagulation, and purpura fulminans. Due to limitations in traditional therapeutic options (anticoagulation, FFP, PCC), plasma-derived protein C concentrates have been used for both prophylactic and therapeutic indications. However, there are few reports of protein C infusion therapy in adults, with limited understanding of pharmacokinetics and no dosing guidelines available. We report the use of protein C concentrate in an individualized dose-finding study, in an adult patient in preparation for renal transplantation.
