Prognostic Factors of Acute Splenic Sequestration

Acute splenic sequestration is a frequent and life threatening complication occurring in approximately 10 % of homozygous children. Maximal incidence is between 6 and 18 months. The investigators formulate the hypothesis that there are clinical, biological and genetic markers predictive of severe complications notably acute splenic sequestration in SCD children. The present research project thus aims at analyzing in a forward-looking way the profile of severity by analysing clinical, biological and genetic characteristics in a multicentric cohort of 60 SCD children
