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 ...
متن کاملThrombotic thrombocytopenic purpura and its diagnosis.
Thrombotic thrombocytopenic purpura (TTP) is a lifethreatening illness whose mortality rate exceeds 90% in the absence of rapid appropriate treatment. Empirical plasmatherapy instituted in the 1970s has reduced the death rate to approximately 25% and both plasma infusions and plasma exchanges remain the only efficient treatments so far. TTP prevalence is about four per one million with a prefer...
متن کاملThrombotic 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...

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...
متن کاملPlatelets: 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...
