About this trial
Sickle cell disease is the most common inherited blood disorder in the world. Chronic hemolysis induces platelet activation and chronic inflammation. Platelets and megakaryocyte, as medullar platelets precursors, are known to play a role in innate immunity. Little is known about the role of megakaryocytes at basal state and during acute complication in sickle cell disease patients. The aim of this study is to evaluate the role of megakaryocytes in sickle cell disease.
