Randomized Controlled Trial Multicenter StudyThrombin generation mediators and markers in sepsis-associated coagulopathy and their modulation by recombinant thrombomodulin.
Severe sepsis remains the most common cause of death in critically ill patients, and thrombin plays a crucial role in the pathogenesis of sepsis-associated disseminated intravascular coagulation (DIC). The purpose of this study was to profile prothrombin fragment (F1.2), thrombin-antithrombin complex (TAT), and d-dimer (DD) throughout the course of hospital stay in patients identified with sepsis. Plasma samples from patients enrolled in the ART-123 study, a phase 2b, international, multicenter, randomized placebo-controlled trial were analyzed for various parameters using enzyme-linked immunosorbent assay methods. ⋯ Although the data were widely scattered, these results show that DIC represents a hypercoagulable state along with other hemostatic abnormalities and the activation of the inflammatory process. Modulation of these activation processes through targets such as DD, F1.2, and TAT may play an important regulatory role in the pathogenesis of sepsis-associated coagulopathy. Moreover, this study validates the hypothesis that thrombomodulin downregulates the thrombin generation mediators/markers in sepsis-associated DIC.
