Comparing long-term outcomes of transplantation versus standard care in sickle cell anemia

Long-term Comparative Cerebrovascular Outcome After Transplantation vs Standard Care in Children With Sickle Cell Anemia ( DREPAGREFFE-2)

Centre Hospitalier Intercommunal Creteil · NCT05053932

This study looks at how kids with sickle cell anemia who had a transplant are doing long-term compared to those who got regular care, focusing on their brain health and overall quality of life.

What this trial studies

This observational study aims to reevaluate a cohort of 67 children with sickle cell anemia who previously participated in a national transplantation protocol. The study focuses on assessing long-term cerebrovascular outcomes, cognitive functioning, and levels of hypoxia/angiogenic factors after 9-10 years. It builds on earlier findings that indicated better quality of life and reduced blood flow velocities in patients who underwent transplantation compared to those receiving standard care. The study will involve blood collection and analysis to further understand the biological factors associated with these outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals who participated in the DREPAGREFFE research protocol for sickle cell anemia between December 2010 and June 2013.

Not a fit: Patients who have refused to participate or are deceased will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the long-term benefits of transplantation over standard care for patients with sickle cell anemia.

How similar studies have performed: Previous studies have shown promising results comparing transplantation to standard care in sickle cell disease, indicating this approach has a foundation of success.
