when to use hydroxyurea in sickle cell disease

Many children with sickle cell disease have taken hydroxyurea for several years without problems. Hydroxyurea is very safe when given by medical specialists experienced in caring for patients with sickle cell disease. In children with sickle cell disease it takes several months to reach the full dose of hydroxyurea. Introduction: Sickle cell disease (SCD) is among the most common inherited hematologic diseases in sub-Saharan Africa (SSA). Historically, hydroxyurea administration in SSA has been restricted due to limited region-specific evidence for safety and digitales.com.au by: The use of hydroxyurea (HU) can improve the clinical course of sickle cell disease. However, several features of HU treatment remain unclear, including the predictability of drug response and determination of adequate doses, considering positive responses and minimal side effects. In order to identi Cited by:

Following the withdrawal of rHuEpo the patients were maintained on HU alone. These results suggest that a hydroxyurea dose of 15 mg kg-1 day-1 seems to be adequate for treatment of sickle cell disease in view of the minimal side effects observed and the improvement in laboratory and clinical parameters. Abstract The use of hydroxyurea HU can improve the clinical course of sickle cell disease. Results: Of patients with SCD, seven 3.

The final Hb and Hb F concentrations, and MCV values were significantly higher than the initial values, while the final reticulocyte and neutrophil counts were significantly lower. Under the targeted use policy, children with SCD demonstrated absolute decreases in the rates of hospitalization The mean baseline hemoglobin F in cohort 1 was Procedures: We performed a retrospective study of patients starting HU at less than five years of age between January 1,and December 31, There was no difference in toxicity between groups. Haematological and relevant biochemical parameters, Hb A2 fetal haemoglobin HbFHbF cells, reticulocytes and platelet counts were estimated at least at three occasions to determine the mean and range of the parameters.

However, several features of HU treatment remain unclear, including the predictability here drug response and determination of adequate doses, considering positive responses and minimal side effects. We evaluated clinical events, laboratory data, and toxicity between three different age groups: cohort 1 yearcohort 2 yearsand cohort 3 years. There was an improvement in the concentration of Hb range: 0. The patients showed a when to use hydroxyurea in sickle cell disease clinical improvement.
