چکیده
The cause of platelet agglutination in thrombotic thrombocytopenic purpura has been an enigma. Current evidence indicates that the interaction of platelets with a platelet-aggregating factor or unusually large multimers of factor Vlllrvon Willebrand factor, or both, may cause the abnormal platelet agglutination. Recent success in the treatment of thrombotic thrombocytopenic purpura with intravenous infusion of immunoglobulin suggests that the abnormal platelet agglutination in thrombotic thrombocytopenic purpura may reflect a deficiency of immunoglobulins that nor mally inhibit platelet-aggregating factors or large multimers of factor VIII:von Willebrand factor.

Successful Treatment of Refractory Thrombotic Thrombocytopenic Purpura with Rituximab, a Monoclonal Antibody: a Case Report
Thrombotic thrombocytopenic purpura (TTP) is mostly attributed to the presence of an autoantibody against ADAMTS-13, a metalloprotease that degrades ultralarge von Willebrand protein multimers. Accumulation of vWF multimers and systemic platelet aggregation lead to microangiopathic thrombosis, hemolytic anemia, and end-organ ischemia. Most patients respond to therapeutic plasma exchange (TPE), ...

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 کاملEfficacy of Rituximab in the Treatment of Plasma Exchange Refractory Thrombotic Thrombocytopenic Purpura
Background: Rituximab can induce a durable remission in plasma exchange refractory thrombotic thrombocytopenic purpura (TTP). Timing of Rituximab infusion in combination with plasma exchange (PE) and long term follow-up for probable side effects of such treatment is still lacking. Methods: This study was conducted among 10 patients with plasma exchange refractory TTP. According to the study de...

Background and Aim: Thrombotic thrombocytopenic purpura is a rare and life-threatening disease with a relatively high prevalence of 5% in pregnancy that causes thrombocytopenia. Due to the high prevalence and mortality of fetal and maternal mortality, which resolves rapidly with the onset of plasmapheresis, the diagnosis of this disease is clinically important. The aim of this study was to succ...
