5. Study Description
Brief Summary
The research proposed is a pilot study of pediatric and adolescent/young adult patients who have received the curative intervention (MSD-SCT), disease-modifying interventions (HU or CT) or SCC (control), with respect to three clinically important outcomes: quality-of-life (QOL), neurocognitive function, and reproductive potential. Comparable cohorts will be identified for each of the groups, drawing from patients treated by the SCD program of Children's Healthcare of Atlanta (CHOA). QOL measures and neuropsychiatric testing and will be administered. Reproductive endocrine function markers (laboratory studies and pubertal staging), will be collected and analyzed. A tracking system of such patients will also be developed, gathering available retrospective data and setting up a mechanism for collection of new data.
Detailed Description
sickle cell disease (SCD), but a significant proportion experience clinically severe disease requiring more aggressive intervention. Widely applicable curative therapy with a favorable toxicity profile remains elusive for such patients.
Three distinct intervention strategies are currently available for children with severe sickle cell disease (SCD): oral hydroxyurea (HU), chronic blood transfusions (CT), and allogeneic hematopoietic stem cell transplantation (SCT) from an HLA-matched sibling donor (MSD). Each intervention has distinct advantages and disadvantages. Many patients do not receive specific intervention, and continue standard comprehensive care (SCC).
Though indications for these therapies overlap, to date there are no comparative outcomes data, leaving families and physicians without adequate information upon which to base therapeutic decisions. The gold standard for obtaining such data would be a randomized, prospective study comparing each intervention, though this may or may not be feasible to conduct. Before such a trial is considered, a large cross-sectional trial should be conducted to establish comparisons among the four therapeutic groups (HU, SCT, CT, SCC) with respect to the outcomes that clinicians and families deem most important.
