INTRODUCTION: The changes in biomarkers of coagulation or fibrinolysis, anticoagulation, inflammation, and endothelial damage occur in patients with systemic inflammatory response syndrome (SIRS). The purpose of this study is to assess the prognostic value of these markers in patients with SIRS-associated hypercoagulopathy. METHODS: Sixty-six SIRS patients with a platelet count less than 15.0 × 10/mm in three university hospital intensive care units were enrolled in this prospective, comparative study. Blood samples were obtained on day 0 and day 2. Twelve hemostatic, inflammatory, and vascular endothelial indices were measured and the data were compared between the severe group (patients with a total maximum Sequential Organ Failure Assessment score of 10 or more and nonsurvivors; n = 25) and the less-severe group (Sequential Organ Failure Assessment score <10; n = 41). RESULTS: Significant changes between the groups were observed in platelet count, fibrin or fibrinogen degradation products, interleukin-6, soluble thrombomodulin, antithrombin (AT) activity, and protein C activity, both on day 0 and on day 2. In contrast, the d-dimer, soluble fibrin, plasmin-α2-antiplasmin complex, and E-selectin levels were higher in the severe group only on day 2. No significant difference was seen regarding the thrombin-AT complex and total plasminogen activator inhibitor on both days. A comparison of the areas under the receiver operating characteristic curve revealed the AT activity to be the best predictor of a progression of organ dysfunction. CONCLUSION: The changes in some hemostatic molecular markers and vascular endothelial markers were conspicuous in patients with organ dysfunction. The AT activity is considered to be the most useful predictor of organ dysfunction.
