Study Summary

The purpose of this study is to determine if hydroxyurea therapy is effective in the prevention of chronic end organ damage in pediatric patients with sickle cell anemia.

Primary Outcome

Primary Endpoint: Spleen function was assessed by uptake of 99mTc sulfur colloid on liver-spleen scan before initiation of treatment (baseline) and 2 years later (exit). The results of each of the two scans were categorized as normal, functional but abnormal, or not functional by a panel of nuclear medicine specialists blinded to treatment assignment. The proportion of patients whose paired scans demonstrated a decline in splenic function was compared in the hydroxyurea versus placebo groups. T
