The Diffuse Vascular Lesion of So-Called "Thrombotic Thrombocytopenic Purpura"

The diffuse vascular lesion of so-called thrombotic thrombocytopenic purpura.

Thrombotic Thrombocytopenic Purpura

Thrombotic microangiopathy comprises a spectrum of clinical and lab findings including microangiopathic hemolytic anemia, thrombocytopenia, and thrombosis of capillary and arterioles. Platelet and hyaline thrombi with complete or partial occlusion of these vessels are integral histopathological findings. These findings are seen irrespective of cause and organ involved. Pathogenesis and prognosi...

Thrombotic thrombocytopenic purpura.

A 6-year-old boy presented with microangiopathic hemolytic anemia, thrombo-cytopenia, altered sensorium and intractable bleeding. A diagnosis of thrombotic thrombocytopenic purpura was made and the child recovered dramatically after plasmapheresis. Recent developments in the understanding of TTP are reviewed, including the importance of a metaloprotease required to cleave multimers of von Willi...

Thrombotic Thrombocytopenic Purpura: Diagnosis and Treatment

Thrombotic Thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathic disease, associated with thrombocytopenia and hemolytic anemia. It is caused by an enzymatic dysfunction responsible in cleavage of blood clotting factors. In this study we have tried to review the available approaches in diagnoses of the disease as well as treatment strategies. Based on the what the current review ...

Platelets: thrombotic thrombocytopenic purpura.

Abnormalities of plasma von Willebrand factor (VWF) have been recognized to be associated with thrombotic thrombocytopenic purpura (TTP) for over 20 years. Patients with chronic, relapsing TTP have VWF multimers that are larger than normal, similar in size to those secreted by cultured endothelial cells. Recent observations have documented that a deficiency of a VWF-cleaving protease (termed AD...
