It is usually caused by inhibition of an enzyme in the blood called ADAMTS13 which breaks down another protein in the blood called Von Willebrand Factor into smaller pieces. TTP is characterized by platelet microthrombi (tiny traveling clots composed of platelets, the clotting cells in the blood), thrombocytopenia (lack of platelets), hemolytic anemia (from the breakup of red blood cells), fever, renal (kidney) abnormalities and neurologic changes such as neurological signs such as aphasia, blindness, and convulsions. TTP is fortunately rare. It occurs at a rate of 3.7 cases per year per million persons. The use of plasma exchange (in which a patient is attached to a machine which filters the blood, removing the plasm- or fluid portion of the blood and returns the blood cells mixed with fresh plasma from donors and other fluids).The mortality (death) rate for promptly treated cases ranges from 10 to 20 percent, down from 90% before use of plasma exchange. Many drugs have been associated with TTP. One is the antiplatelet drug clopidogrel (Plavix). The purpura refers to sizable bruises due to bleeding into the skin. • How to pronounce Purpura, thrombotic thrombocytopenic (TTP) • definition of Purpura, thrombotic thrombocytopenic (TTP) • audio dictionary • How to say Purpura, thrombotic thrombocytopenic (TTP) • What is the meaning of Purpura, thrombotic thrombocytopenic (TTP) • Pronounce Purpura, thrombotic thrombocytopenic (TTP) • Medical dictionary • Medical definition of Purpura, thrombotic thrombocytopenic (TTP)
