Three-Year Follow-Up of Hydroxyurea Treatment in Severely Ill Children with Sickle Cell Disease

Abstract

Our data support the efficacy of HU in reducing painful events in children with sickle cell disease. Short- and middle-term tolerances are good. Thus, we think that HU can be given to children affected by frequent and severe painful crises. We recommend, however, very cautious use of this drug, because its long-term effects in children are still unknown.
