Curative Therapies for Sickle Cell Disease

Epub 2024 Feb 1.ABSTRACTSickle cell disease (SCD) is an autosomal recessive hemoglobinopathy that affects individuals worldwide. The mutation in the beta-globin gene leads to abnormal hemoglobin production, sickle hemoglobin, which polymerizes under stress leading to, among other end-organ manifestations, chronic hemolytic anemia, debilitating vaso-occlusive crises, and stroke. Unfortunately, chronic stress on end-organs impacts the life expectancy of patients with SCD, which in the United States averages 43 years, approximately 36 years less than people without the disease. Here, we review the progress made in curative interventions for those with SCD, namely allogeneic hematopoietic cell transplantation and gene therapy. These interventions continue to evolve as we better understand SCD pathophysiology, use new graft-versus-host disease prophylaxis regimens, expand stem cell donor options, and understand the genetic control of hemoglobin production. Although significant progress has been made, many gaps remain in the successful implementation of these interventions globally and for all patients.
