Epilepsy, a chronic brain disorder characterized by abnormal brain activity that causes seizures and other symptoms, is typically treated using anti-epileptic drugs (AEDs) as the first-line therapy. However, due to the variations in their modes of action, identification of effective AEDs often relies on ad hoc trials, which is particularly challenging for pediatric patients. Thus, there is significant value in computational methods capable of assisting in the selection of AEDs, aiming to minimize unnecessary medication and improve treatment efficacy.
In this study, we collected 7,507 medical records from 1,000 pediatric epilepsy patients and developed a computational clinical decision-supporting system for AED selection. This system leverages three multi-channel convolutional neural network (CNN) models tailored to three specific AEDs (vigabatrin, prednisolone, and clobazam). Each CNN model predicts whether a respective AED is effective on a given patient or not. The CNN models showed AUROCs of 0.90, 0.80, and 0.92 in 10-fold cross-validation, respectively. Evaluation on a hold-out test dataset further revealed positive predictive values (PPVs) of 0.92, 0.97, and 0.91 for the three respective CNN models, representing that suggested AEDs by our models would be effective in controlling epilepsy with a high accuracy and thereby reducing unnecessary medications for pediatric patients.
Our CNN models in the system demonstrated high PPVs for the three AEDs, which signifies the potential of our approach to support the clinical decision-making by assisting doctors in recommending effective AEDs within the three AEDs for patients based on their medical history. This would result in a reduction in the number of unnecessary ad hoc attempts to find an effective AED for pediatric epilepsy patients.
癫痫是一种慢性脑部疾病,其特征是异常的大脑活动导致癫痫发作和其他症状。通常使用抗癫痫药物(AEDs)作为一线治疗。然而,由于它们的作用模式不同,确定有效的 AED 通常依赖于特定的试验,这对于儿科患者尤其具有挑战性。因此,需要有能够协助选择 AED 的计算方法,旨在减少不必要的药物治疗并提高治疗效果。
在这项研究中,我们从 1000 名儿科癫痫患者中收集了 7507 份病历,并开发了一种用于选择 AED 的计算临床决策支持系统。该系统利用三个针对三种特定 AED(氨己烯酸、泼尼松龙和氯巴占)的多通道卷积神经网络(CNN)模型。每个 CNN 模型预测特定 AED 是否对给定患者有效。CNN 模型在 10 倍交叉验证中分别显示出 0.90、0.80 和 0.92 的 AUROC。在保留测试数据集上的评估进一步揭示了三个 CNN 模型的阳性预测值(PPV)分别为 0.92、0.97 和 0.91,这表明我们的模型建议的 AED 以高准确性控制癫痫发作,从而减少儿科患者不必要的药物治疗。
我们系统中的 CNN 模型对三种 AED 表现出高 PPV,这表明我们的方法有可能通过根据患者的病史,协助医生在三种 AED 中推荐有效的 AED,从而支持临床决策。这将减少为儿科癫痫患者找到有效 AED 的不必要特定尝试的数量。
