Low levels of coagulation inhibitors: a high-risk thrombotic factor in thalassemic patients

Abstract

Background and aimThe β-thalassemia major (β-TM) is defined as a hereditary red blood cell (RBC)- related disease. Thrombotic events are associated with thalassemia in adult patients. Thus, the present investigation was aimed to examine some hemostatic parameters, including anti thrombin- III (AT-III), protein-C (PRC) and protein-S (PRS) in β-TM patients. MethodsThirty B-TM patients who referred for routine follow-up admission to the thalassemia clinic of Kerman Special Disease Center alongside with 30 healthy subjects were selected and enrolled in the present study. Further registration, the peripheral blood specimens were collected after 3 weeks of last transfusion and then the plasma concentrations of AT-III, PRC and PRS were measured in them. ResultsWe have observed that the concentrations of natural coagulation inhibitors (PRC and PRS) were significantly attenuated in β-TM patients (P < 0.05), while the plasma level of AT-III was not remarkably differed in β-TM patients in compare to healthy subjects. ConclusionAccording to the findings of present work, significant changes in the PRC, PRS and AT-III which could be observed in multi transfused β-TM patients may attribute as critical risk factors for the development of upcoming thromboembolic events in their future life.
