Human protein C zymogen concentrate in patients with severe sepsis and multiple organ failure after adult cardiac surgery.

摘要

PURPOSE: To describe outcome and changes in clotting and inflammatory parameters in an uncontrolled case series of consecutive patients with severe sepsis who received protein C concentrate soon after cardiac surgery. METHODS: From January 2007 to January 2008 nine consecutive adult patients with severe sepsis or septic shock and two or more organ failure after cardiac surgery received protein C concentrate, 50 IU/kg as a bolus followed by continuous infusion of 3 IU/kg per hour for 72 h. RESULTS: The increase in protein C levels was accompanied by an early drop in interleukins and near-normalization of prothrombin time, activated partial thromboplastin time, antithrombin and thrombin-antithrombin complex levels (p < or = 0.03). No patient experienced drug-related side effects. Thirty-day mortality was 11% (1 patient) compared to the expected mortality of 68%. CONCLUSIONS: In this pilot, uncontrolled study of nine patients with sepsis-induced double organ failure following cardiac surgery, treatment with protein C concentrate was associated with significant improvement in clinical, inflammatory and clotting parameters, no bleeding and low 30-day mortality.
