Hydroxyurea sickle cell anemia
WebTaken together, these data suggest that the improved rheological properties of sickle erythrocytes in vivo are due to the elevated numbers of F cells [cells with fetal hemoglobin]. The presence of the nitrosyl hemoglobin or methemoglobin from the reaction with hydroxyurea may also benefit patients in vivo by reducing sickling. WebAlthough it is generally assumed that the benefit of HU is due to an increase in Hb F levels, a multivariable analysis of data from the Multicenter Study of Hydroxyurea in Sickle Cell Anemia (MSH) showed that the percentage of F cells was inversely correlated with the rate of painful crises only during the first three months of therapy. 131 However, there was a …
