[Sepsis and blood coagulation].
Septicemia is frequently accompanied by changes in the plasmatic as well as cellular coagulation systems and by microclot formation. The occurrence of a hemorrhagic diathesis and microthrombosis is best explained by the syndrome disseminated intravascular coagulation (= consumption coagulopathy). Disseminated intravascular coagulation can be initiated by different agents and by different pathways. The activation of coagulation by endotoxin is well studied; it is mediated by synthesis of tissue factor by monocytes and endothelial cells. The formation of microthrombi is caused by the precipitation of circulating soluble fibrin under the influence of localizing factors, and it is observed under conditions of reduced fibrinolysis activation. Furthermore, thrombocytopenia, thrombocytopathy and endothelial cell damage caused by a direct effect of the toxic agent contribute to the bleeding diathesis.
