Kidney transplantation is the treatment of choice for patients with end-stage renal disease (ESRD). Prediction of the transplant survival is of paramount importance. The objective of this study was to develop a model for predicting survival in kidney transplant recipients. In a cross-sectional study, 717 patients with ESRD admitted to Nemazee Hospital during 2008-2012 for renal transplantation were studied and the transplant survival was predicted for 5 years. The multilayer perceptron of artificial neural networks (MLP-ANN), logistic regression (LR), Support Vector Machine (SVM), and evaluation tools were used to verify the determinant models of the predictions and determine the independent predictors. The accuracy, area under curve (AUC), sensitivity, and specificity of SVM, MLP-ANN, and LR models were 90.4%, 86.5%, 98.2%, and 49.6%; 85.9%, 76.9%, 97.3%, and 26.1%; and 84.7%, 77.4%, 97.5%, and 17.4%, respectively. Meanwhile, the independent predictors were discharge time creatinine level, recipient age, donor age, donor blood group, cause of ESRD, recipient hypertension after transplantation, and duration of dialysis before transplantation. SVM and MLP-ANN models could efficiently be used for determining survival prediction in kidney transplant recipients.
肾移植是终末期肾病(ESRD)患者的首选治疗方法。预测移植肾存活至关重要。本研究的目的是建立一个预测肾移植受者存活的模型。在一项横断面研究中,对2008年至2012年期间入住内马齐医院进行肾移植的717例ESRD患者进行了研究,并对其移植肾存活情况进行了5年的预测。使用人工神经网络的多层感知器(MLP-ANN)、逻辑回归(LR)、支持向量机(SVM)和评估工具来验证预测的决定因素模型,并确定独立预测因子。SVM、MLP-ANN和LR模型的准确性、曲线下面积(AUC)、敏感性和特异性分别为90.4%、86.5%、98.2%和49.6%;85.9%、76.9%、97.3%和26.1%;以及84.7%、77.4%、97.5%和17.4%。同时,独立预测因子为出院时肌酐水平、受者年龄、供者年龄、供者血型、ESRD病因、移植后受者高血压以及移植前透析时间。SVM和MLP-ANN模型可有效地用于确定肾移植受者的存活预测。
