“…TFPI consists of three Kunitz type inhibitory domains [7]; the second Kunitz domain is the FXa inhibitor, while the first domain is responsible for FVIIa/tissue factor (TF) inhibition [8]. Disseminated intravascular coagulation (DIC) [9,10], a condition associated with severe bleeding tendency and organ failure and sometimes exhibiting a very rapid and severe clinical course, appears to be related to vascular endothelial cell injury. Recently, plasma levels of other agents involved in the coagulation cascade, i.e., thrombomodulin (TM), tissue type plasminogen activator (t-PA), plasminogen activator inhibitor-I (PAI-I), and von Willebrand Factor (vWF), all of which are released from vascular endothelial cells, have been reported [11,12].…”
