What this research studies

If your child has sickle cell anemia, this program offers hydroxyurea treatment and follows children prospectively at clinics in four African countries. The effort began with neonatal screening to diagnose infants and then started hydroxyurea, gradually increasing each child's dose to their maximum tolerated level. Over 600 children received treatment and the teams collected more than 3,000 patient‑years of safety and outcome data, despite COVID challenges. Clinics tracked sickle‑related events, side effects, and practical delivery issues to show whether routine use of hydroxyurea is safe and feasible in these settings.

Who could benefit from this research

Good fit: Young children (newborns through about 11 years) diagnosed with sickle cell anemia at participating sites in sub‑Saharan Africa are the ideal candidates.

Not a fit: Children without sickle cell anemia, adults, or patients with medical contraindications to hydroxyurea (for example severe bone marrow suppression) would not be expected to benefit from this specific program.

Why it matters

Potential benefit: If successful, this work could lower pain crises, infections, hospitalizations, and early deaths among children with sickle cell anemia in sub‑Saharan Africa.

How similar studies have performed: Hydroxyurea has a long history of success in children with sickle cell disease in high‑income countries, but REACH is among the first large programs testing safe dosing and delivery across multiple African settings.
