Answer

Subclinical coagulopathy, signaled by a mild elevation of the thrombin time (TT) or activated partial thromboplastin time (aPTT) or a moderate reduction in the platelet count, is extremely common; however, overt disseminated intravascular coagulation (DIC) may also develop. Protease-activated receptors (PARs), especially PAR 1, form the molecular link between coagulation and inflammation; PAR1 exerts cytoprotective effects when stimulated by activated protein C or low-dose thrombin but exerts disruptive effects on endothelial-cell barrier function when activated by high-dose thrombin.
