Abstract

OBJECTIVES: To synthesize the published literature on the efficacy, effectiveness, and toxicity of hydroxyurea (HU) when used for treatment of sickle cell disease (SCD); and to review the evidence regarding barriers to its use. DATA SOURCES: Articles cited in MEDLlNE, EMBASE, TOXLine, and CINAHL through June 30, 2007. REVIEW METHODS: Paired reviewers reviewed each title, abstract, and article to assess eligibility. They abstracted data sequentially and then independently graded the evidence. RESULTS: In one small, randomized trial of HU in children with SCD; the yearly hospitalization rate was lower with HU than placebo (1.1 versus 2.8, p=0.002). The absolute increase in fetal hemoglobin (Hb F%) was 10.7 percent. Twenty observational studies of HU in children reported similar increases in Hb F%, while hemoglobin concentration increased by roughly 1 g/dl. One large randomized trial tested the efficacy of HU in adults with SCD and found that after 2 years of treatment, Hb F% increased by 3.2 percent and hemoglobin increased by 0.6 g/dl, The median number of painful crises was 44 percent (p
