Modelling of Sickle Cell Anemia Patients Response to Hydroxyurea using Artificial Neural Networks
This addresses a critical decision-making problem for physicians treating sickle cell anemia patients, helping avoid unnecessary harmful effects in non-responsive individuals, though it is incremental as it applies existing neural network methods to a specific medical dataset.
The paper tackled the problem of predicting which sickle cell anemia patients will respond positively to Hydroxyurea therapy, using deep artificial neural networks on blood sample data from 122 patients, achieving 92.6% accuracy in predicting final HbF values.
Hydroxyurea (HU) has been shown to be effective in alleviating the symptoms of Sickle Cell Anemia disease. While Hydroxyurea reduces the complications associated with Sickle Cell Anemia in some patients, others do not benefit from this drug and experience deleterious effects since it is also a chemotherapeutic agent. Therefore, to whom, should the administration of HU be considered as a viable option, is the main question asked by the responsible physician. We address this question by developing modeling techniques that can predict a patient's response to HU and therefore spare the non-responsive patients from the unnecessary effects of HU on the values of 22 parameters that can be obtained from blood samples in 122 patients. Using this data, we developed Deep Artificial Neural Network models that can predict with 92.6% accuracy, the final HbF value of a subject after undergoing HU therapy. Our current studies are focussing on forecasting a patient's HbF response, 30 days ahead of time.
