Elevated plasma levels of fibrin degradation products by granulocyte-derived elastase in patients with disseminated intravascular coagulation

Abstract

Plasma levels of granulocyte-derived elastase (GE-XDP), D-dimer, and soluble fibrin (SF) were examined in 177 patients with disseminated intravascular coagulation (DIC) of various etiologies. Plasma levels of GE-XDP and D-dimer, but not SF, were significantly high in patients with sepsis and solid cancer. The ratio of GE-XDP/D-dimer was significantly high in patients with trauma, burn, and sepsis, suggesting that fibrinolysis due to GE-XDP may be dominant in DIC. Plasma levels of GE-XDP and D-dimer, but not SF, were significantly high in patients with overt DIC and correlated with DIC score. Plasma levels of GE-XDP, but not SF, correlated significantly with D-dimer. Plasma levels of D-dimer, but not SF, correlated significantly with plasmin plasmin inhibitor complex (PPIC). Plasma levels of GE-XDP and D-dimer, but not SF, were significantly high in nonsurvivors. Plasma levels of GE-XDP, but not SF, correlated significantly with sepsis-related organ failure assessment (SOFA) score. These results suggest that GE-XDP is a potentially useful marker for the diagnosis of overt-DIC and as a predictor of organ failure-related outcome. ©2005 Westminster Publications, Inc.
