 Thrombotic Thromboctyopenic Purpura
Thrombotic thrombocytopenic purpura (TTP) is a rare blood condition characterized by the formation of small clots (thrombi) within the circulation, which results in the consumption of platelets and thus a low platelet count (thrombocytopenia).
The first case of TTP was described by Moschcowitz, in 1925, in which a 16 year old female was admitted to the hospital with an acute and fatal illness that included stroke and heart failure.
Thrombotic Thrombocytopenic Purpura and Hemolytic Uremic Syndrome were once thought to represent opposite ends of the spectrum of the same disease process and are classified by some as thrombotic microangiopathy (TMA).

 Thrombotic thrombocytopenic purpura (TTP)
Thrombotic thrombocytopenic purpura (TTP) is a rare blood condition characterised by the formation of small clots (thrombi) within the circulation, which results in the consumption of platelets and thus a low platelet count (thrombocytopenia).
Most adult-onset TTP appears to be secondary to the development of an antibody that inhibits this enzyme activity, whereas the childhood form is due to a simple reduction in enzyme activity.
TTP can occur in late pregnancy or even after the birth and as it can also cause high blood pressure TTP can sometimes be hard to distinguish from eclampsia.

This Request for Application (RFA), Thrombotic Thrombocytopenic Purpura and HIV, is related to the priority areas of heart disease and stroke, and HIV infection.
This has fueled the debate about whether the clinical manifestations of TTP result from a missing plasma factor that inhibits aggregation (which is replaced during plasma infusion) or a platelet aggregatory factor that is not normally present in plasma (which is removed during plasmapheresis).
A recent controlled trial of plasma exchange versus plasma infusion in patient with TTP of all origins, except HIV infection, demonstrated the superiority of plasma exchange, although proponents of plasma infusion argue that plasma exchange merely allows a greater volume of plasma to be infused.

Thrombotic Thrombocytopenic Purpura (TTP) is a rare blood disorder that usually develops as a result of a severe bacterial or viral infection elsewhere in the body, often as a result of an E. Coli infection.
Left to progress unchecked, TTP is often fatal, and it very nearly killed me. Apparently, I was a victim of acute idiopathic (unknown-cause) TTP, although to this day I will swear that it was brought about as a result of a gallbladder inflammation due to cholelithiasis (gallstones) in the common bile duct.

 Hemolytic-Uremic Syndrome (HUS) & Thrombotic Thrombocytopenic Purpura (TTP) - nephrologychannel
Hemolytic-uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are microangiopathic disorders—that is, they are characterized by abnormalities (chiefly blood clots) that occur within the small blood vessels of the body.
Although the exact cause(s) of HUS and TTP are unknown, experts believe that an abnormal, inflammatory reaction within the blood stimulates the deposition of platelet-rich thrombi.
Purpura (bleeding into the tissues) sometimes can be seen in the skin, and patients often complain of tiredness due to anemia.

 Symptoms of Thrombotic Thrombocytopenic Purpura (TTP)
In the study published by Silverstein (1968), involving over 300 patients with Thrombotic Thrombocytopenic Purpura, 90% of the patients had neurologic involvement and the illness began as a neurologic one in 60% of the patients.
In a more recently published study by Bakashi (1999), on 12 patients with Thrombotic Thrombocytopenic Purpura, clinical neuroimaging revealed a variety of brain lesions, which included reversible cerebral edema lesions which resembled RPLS (reversible posterior leukoencephalopathy syndrome) and were seen in patients with hypertension and renal dysfunction.
Since TTP is a diffuse disease involving virtually every organ in the body, and because some of the patients studied had cardiac rhythm disturbances, as well as sudden cardiac arrest, it was important to investigate the potential effects of this disease on the heart and the conduction system.

Thrombotic thrombocytopenic purpura (TTP) is a clinical syndrome which consists of microangiopathic hemolytic anemia, thrombocytopenia, and fever, along with a variable degree of renal insufficiency and fluctuating neurologic abnormalities.
TTP occurs in a heterogeneous group of patients with an increased incidence and association with pregnancy, autoimmune conditions, infections, malignancy and certain medications.
Clinical response to the management of TTP is dependent upon the etiology, with cancer and chemotherapy-associated TTP being less responsive to conventional therapy.
