2017 年,Toulouse-Rangueil 队列开发了一种估计捐赠后肾小球滤过率 (eGFR) 和 1 年 CKD 风险的预测模型,该模型与观察到的 1 年捐赠后 eGFR 具有良好的相关性。我们回顾性分析了 1998 年至 2020 年在单一中心进行的所有活体肾移植手术。将捐赠后 1 年使用 CKD-EPI 公式观察到的 eGFR 与使用 eGFR 公式预测的 eGFR (CKD-EPI, mL/min/1.73 m2) = 31.71+ (0.521 × 术前 eGFR) − (0.314 × 年龄) 进行比较。 333 名捐赠者接受了评估。预测和观察到的 1 年捐赠后 eGFR 之间存在良好的相关性(Pearson r = 0.67;p < 0.001)和一致性(Bland-Altman 图,一致性限为 95% -21.41–26.47 mL/min/1.73 m2;p < 0.001)。 ROC 曲线下面积显示该公式在预测捐赠后 1 年观察到的 CKD 方面具有良好的判别能力(AUC = 0.83;95% CI:0.78–0.88;p < 0.001),最佳截止值对应于 65.25 mL/min/1.73 m2 的预测 eGFR,其中预测 CKD 的敏感性和特异性分别为77%和75%。该模型在我们的队列(不同的欧洲人群)中成功得到了验证。它是一个简单而准确的工具,可以帮助评估潜在的捐助者。
A predictive model to estimate post-donation glomerular filtration rate (eGFR) and risk of CKD at 1-year was developed from a Toulouse-Rangueil cohort in 2017 and showed an excellent correlation to the observed 1-year post-donation eGFR. We retrospectively analyzed all living donor kidney transplants performed at a single center from 1998 to 2020. Observed eGFR using CKD-EPI formula at 1-year post-donation was compared to the predicted eGFR using the formula eGFR (CKD-EPI, mL/min/1.73 m2) = 31.71+ (0.521 × preoperative eGFR) − (0.314 × age). 333 donors were evaluated. A good correlation (Pearson r = 0.67; p < 0.001) and concordance (Bland-Altman plot with 95% limits of agreement −21.41–26.47 mL/min/1.73 m2; p < 0.001) between predicted and observed 1-year post-donation eGFR were observed. The area under the ROC curve showed a good discriminative ability of the formula in predicting observed CKD at 1-year post-donation (AUC = 0.83; 95% CI: 0.78–0.88; p < 0.001) with optimal cutoff corresponding to a predicted eGFR of 65.25 mL/min/1.73 m2 in which the sensibility and specificity to predict CKD were respectively 77% and 75%. The model was successfully validated in our cohort, a different European population. It represents a simple and accurate tool to assist in evaluating potential donors.
