Evaluation of clinical symptom, laboratory finding and prognosis in thrombotic thrombocytopenic purpura patient from 2010 t0 2017. A single-center retrospective study

Background: and purpose: thrombotic thrombocytopenic purpura (TTP) is associated with microangiopathic hemolytic anemia, thrombocytopenia, and micro vascular thrombus plus fever, fluctuating neurologic abnormalities and renal damage. The purpose of this study was to investigate clinical symptom, laboratory finding and prognosis in TTP patient from 2010 to 2017 in Shariati hospital. In the present study we assessed clinical presentation and laboratory finding to predict mortality in patients with TTP. Methods: the study was a retrospective cohort study in patient with TTP in Shariati hospital from 2010 to 2017. 114 subjects with TTP after rule out of other microangiopathic hemolytic anemia were included in this study. Results: 114 case of TTP (80 female and 34 male) were identified. Mean ages of participated in the study were 39 years. Hematologic and neurologic symptoms were most common manifestations. Laboratory result at the time of diagnosis revealed mean thrombocytopenia (Plt: 29100), anemia (Hb:8/1), elevated LDH (15100).all patient were treated with PEX, using a cut-off value for the platelet count of 150000/ml. 75% of patient responded . In this study mean of ages, Neurologic manifestation, category of immunologic and reticulocyte count predicted mortality. Conclusion: finally, it can be concluded that mortality rate similar to other study but: in difference clinical symptom and laboratory finding may be predict mortality and occurrence of relapse.
