In children, hematopoietic stem cell transplant from HLA-identical sibling can stop the progression of the disease and leads to more than 95% long-term free survival without sickle cell disease. The aim of this workshop was to define indications and modalities of allogeneic hematopoietic stem cell transplant in children and adults with sickle cell disease. Patient and sibling HLA typing should be proposed, early in the course of the disease, when intensification therapies are required. Indications of transplant from HLA-identical sibling in children and adults are, cerebral vasculopathy, occurrence of vaso-occlusive events despite hydroxycarbamide, renal and hepatic diseases related to SCD, chronic anemia<7g/dL despite hydroxycarbamide, need to maintain transfusion programs longer than six months, and major transfusion difficulties related to red blood cell alloimmunization. In children with an HLA-identical sibling donor, we recommend a myeloablative conditioning regimen associating high dose busulfan, cyclophosphamide and ATG, considering ...
