Global fibrinolytic capacity in pediatric patients with sepsis and disseminated intravascular coagulation.
There are many complex pathophysiologic changes of the coagulation system in sepsis. The fibrinolytic system was evaluated in septic children using the global fibrinolytic capacity (GFC), a new technique reflecting the overall fibrinolytic activity. The study consisted of 24 children with sepsis, 36 children with sepsis plus disseminated intravascular coagulation (DIC), and 20 healthy age-matched control individuals. Compared with controls, 86% of sepsis patients and 87% of sepsis plus DIC patients had decreased GFC levels. Between the sepsis plus DIC and sepsis groups there was no significant difference in terms of GFC levels. While 19 patients (52.7%) died in the sepsis plus DIC group, only three patients (12.5%) died in the sepsis group. When survivors and nonsurvivors were compared in terms of coagulation tests, there were significant differences for protein C, antithrombin, platelet, fibrinogen, aspartate aminotransferase, alanine aminotransferase, prothrombin time, and white blood cell values. In conclusion, the level of GFC reduced in most of the pediatric sepsis patients but no difference was observed between patients with sepsis and patients with sepsis plus DIC. While inhibition of fibrinolysis is an important finding in sepsis, the mortality is mainly associated with the presence of end-organ damage and the status of coagulation parameters.
