Sickle cell anemia is one of the most common hemoglobinopathies in the worldwide. Sickle cell anemia characterized by crises and organ failure develops over time. Myeloablative stem cell transplantation is curative but it has been performed in children younger than 16 years of age. Modest modifications in the conditioning regimen and supportive care have improved outcome such that the majority of children with a suitable HLA-matched sibling donor can expect a cure from this approach. But nonmyeloablative protocols are crucial for the future of Hematopoietic Stem-Cell Transplantation for older sickle cell anemia patients with organ failure. A protocol for nonmyeloablative allogeneic hematopoietic stem-cell transplantation that includes total-body irradiation and treatment with alemtuzumab and sirolimus can achieve stable, mixed donorrecipient chimerism. Stem cell transplantation is recommended in the presence of HLA-matched siblings in patients at risk.
