Allogeneic Genoidentical Stem Cell Transplantation in Children With Sickle-cell Anemia and Cerebral Vasculopathy (DREPAGREFFE)
December 2, 2016 updated by: Assistance Publique - Hôpitaux de Paris
A Multicenter Study Comparing the Results of Allogeneic Stem Cell Genoidentical in Children With Sickle Cell Anemia and Cerebral Vascular Disease Detected by Transcranial Doppler
The aim of this study is to demonstrate that cerebral velocities assessed by transcranial doppler (TCD) are more significantly decreased by SCT than by long-term transfusion program A multicenter, national, non-randomized, prospective study of paired cohort will be conducted, with 2 groups of exposed (SCT) and non-exposed (TP) patients.

Detailed Description
The aim of this study is to demonstrate that cerebral velocities assessed by transcranial doppler (TCD)are more significantly decreased by SCT than by long-term transfusion program A multicenter, national, non-randomized, prospective study of paired cohort will be conducted, with 2 groups of exposed (SCT) and non-exposed (TP) patients.
Sixty-three patients will be enrolled, namely 21 sickle-cell patients in the "SCT" group and 42 in the "Transfusion Program (TP)" group
