Hemoglobin Response Modeling under Erythropoietin Treatment: Physiological Model-Informed Machine Learning Method
October 21, 2022
Patients with renal anemia (RA) are usually treated with recombinant human erythropoietin (EPO) because of insufficient renal EPO secretion. The establishment of a good hemoglobin (Hgb) response model is a necessary condition for dose optimization design. The purpose of this paper is to apply physics-informed neural networks (PINN) to build the Hgb response model under EPO treatment. Neural network training is guided by physiological model to avoid overfitting problem. During the training process, the parameters of the physiological model can be estimated simultaneously. To handle differential equations with impulse inputs and time delays, we propose approximate analytical expressions for the pharmacokinetic (PK) model and weighted formulations for the pharmacology (PD) model, respectively. The improved PK/PD model was incorporated into PINN for training. Tests on simulated data show that the proposed method has good performance.
