| Outline of Final Research Achievements |
As presented in the interim report of last year, we have measured damage-associated molecular patterns (DAMPs) (histone H3, H4), molecules in complement pathways (C3a, C5a), and major anticoagulant molecules, activated protein C, in patients with sepsis and trauma. In addition, we studied relationships between disseminated intravascular coagulation (DIC) and activated protein C to investigate pathophysiological roles of coagulation and fibrinolysis. Based on these results, we came to conclusion that in trauma patients with DIC, endothelial cells injury as well as reduction of activated protein C synergistically induces disseminated thrombin generation in the whole-body circulation. Disseminated thrombin generation, so-called DIC gives rise to multiple organ dysfunction, leading to worse outcome of trauma patients.
