In both normal and abnormal vascular biology, platelet-leukocyte-RBC-EC adhesive and functional interactions appear to play a significant role. The clinical hallmarks of the TTP/HUS syndromes, including prominent platelet aggregation and thrombi without prominent soluble coagulation system activation along with microangiopathic hemolysis, suggest that such interactions may help to bring a common theme of explanation to this disorder. However, a final unifying physiological pathway remains elusive.

D011697	Purpura, Thrombotic Thrombocytopenic	An acquired, congenital, or familial disorder caused by PLATELET AGGREGATION with THROMBOSIS in terminal arterioles and capillaries. Clinical features include THROMBOCYTOPENIA; HEMOLYTIC ANEMIA; AZOTEMIA; FEVER; and thrombotic microangiopathy. The classical form also includes neurological symptoms and end-organ damage, such as RENAL FAILURE. Mutations in the ADAMTS13 PROTEIN gene have been identified in familial cases.
