    Abstract:
    We have treated 9 patients with sickle cell anemia (SS) with hydroxyurea (HU). All 9 patients carried 4 alpha-globin genes and the beta s-globin haplotypes 19/19 (Benin/Benin), except for 1 who had haplotype 19 together with type 3 (Benin/Senegal). Six patients received HU for 10 months and were again treated with the drug for 5 months after an interval of 1 year. One patient was given HU for 22 consecutive months. A record was kept of hematological and biochemical data, Hb F and G gamma levels, as well as possible clinical complications. Our data show that HU generally improves the hematological and biochemical values and the level of Hb F, and reduces painful crises in some patients. However, although the clinical symptoms improved in some patients during HU therapy, the older patients did not observe any changes in their general condition; the same is the case for the patient with haplotype 19/3. One patient also experienced life-threatening liver sequestration during treatment. We conclude that the selection of patients who may benefit from HU therapy needs further evaluation.
