Abstract :
The study described in this paper was undertaken to develop the ability to predict the response of sickle-cell patients to hydroxyurea (HU) therapy. We monitored and analyzed the effect of HU on the value of Fetal Hemoglobin (HbF) of 83 patients in order to develop a predictive model for the effect of HU on HbF. Correlation analysis failed to establish a statistically significant relationship between any of the 23 parameters collected from each patient and the magnitude of the HbF response. Linear regression analysis also failed to predict a patient´s response to HU. On the other hand, artificial neural network (ANN) pattern recognition analysis of the 23 parameters predicts, with 86.6% accuracy, those patients that respond positively to HU and those that do not
