Thrombotic thrombocytopenic purpura is a rare type of microangiopathic hemolytic anemia caused by a defciency of ADAMTS 13 protein whose mortality without treatment is 90%. In our hospital we cannot quantify this protein. Diagnostic should be strongly suspected in the presence of hemolytic anemia, thrombocytopenia and peripheral blood schistocytes. We describe 3 cases, the frst of a 52 years with idiopathic acquired TTP requiring plasma exchange and steroids without good response. Given the refractoriness was necessary administration of Rituximab, Cyclophosphamide and Vincristine. The second case, a 42 year old female patient with Anti DNA antibody positivity develops a PTT with impairment of consciousness, hemiparesis and seizures that required treatment in intensive care, after 5 sessions of plasmapheresis and steroids had a favorable outcome. The third case, 45 years old male patient who presents with dyspnea, diagnosis of TTP is documented by abundant Schistocytes in peripheral blood, develops secondary acute respiratory failure and died. At autopsy is was found a massive right ventricular infarction. We consider a contribution to the literature this description of cases especially by heterogeneity of presentation and response to treatment.
