In medicine and hematology, thrombotic thrombocytopenic purpura (TTP) is "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."[1]
Etiology/cause
Patients with primary TTP may have low von Willebrand factor-degrading protease (ADAMTS13 protein), an ADAM Protein.[2] This deficiency allows thrombi due to von Willebrand Factor (vWF)
Diagnosis
In the Oklahoma registry, 23% (60/261) patients with idiopathic thrombotic thrombocytopenic purpura had ADAMTS13 activity of less than 10%.[2][3]
