即使考虑到捐献前的特征,捐献后 eGFR 的降低与活体肾脏捐献后 ESRD 的较高风险相关。 Toulouse-Rangueil 模型 (TRM) 估算捐献后 12 个月的 eGFR (eGFR12),以便为活体捐献候选人提供咨询。 TRM 在多个单中心欧洲队列中得到了验证,但尚未在美国捐赠者中得到验证。我们使用 1/2000-6/2021 的 SRTR 数据评估了美国活体肾脏捐赠者的 TRM。我们将 2021 年 CKD-EPI 方程 eGFR12 观察到的估计值与 TRM eGFR12 预测值进行了比较。中位 (IQR) 偏差为 -3.4 (-9.3, 3.4) mL/min/1.73 m2。男性与女性的偏差较高(偏差[IQR] −4.4 [−9.9, 1.8] vs. −2.9 [−8.8, 4.1]),年轻(31–40)与老年捐赠者(>50)的偏差较高(偏差 −4.9 [−10.6, 3.0] vs. −2.1 [−7.5, 4.0])。黑人与白人捐赠者的偏差也更大(偏差(−6.7 [−12.1,−0.3],p < 0.001)与(−3.4 [−9.1,3.1],p < 0.001))。总体相关性为 0.71。在使用 2009 CKD-EPI 方程进行的敏感性分析中,结果总体一致,但总体偏倚较高(偏倚 −4.2 [−9.8, 2.4])。 TRM 高估了美国捐赠者的捐赠后肾功能。对于那些捐献后 ESRD 风险较高的人(包括男性、黑人和年轻捐献者),高估的情况最为严重。需要一个新的方程来估计捐赠后肾功能。
Decreased postdonation eGFR is associated with a higher risk of ESRD after living kidney donation, even when accounting for predonation characteristics. The Toulouse-Rangueil model (TRM) estimates 12 month postdonation eGFR (eGFR12) to inform counseling of candidates for living donation. The TRM was validated in several single-center European cohorts but has not been validated in US donors. We assessed the TRM in living kidney donors in the US using SRTR data 1/2000–6/2021. We compared the 2021 CKD-EPI equation eGFR12 observed estimates to the TRM eGFR12 predictions. Median (IQR) bias was −3.4 (−9.3, 3.4) mL/min/1.73 m2. Bias was higher for males vs. females (bias [IQR] −4.4 [−9.9, 1.8] vs. −2.9 [−8.8, 4.1]) and younger (31–40) vs. older donors (>50) (bias −4.9 [−10.6, 3.0] vs. −2.1 [−7.5, 4.0]). Bias was also larger for Black vs. White donors (bias (−6.7 [−12.1, −0.3], p < 0.001) vs. (−3.4 [−9.1, 3.1], p < 0.001)). Overall correlation was 0.71. In a sensitivity analysis using the 2009 CKD-EPI equation, results were generally consistent with exception to a higher overall bias (bias −4.2 [−9.8, 2.4]). The TRM overestimates postdonation renal function among US donors. Overestimation was greatest for those at higher risk for postdonation ESRD including male, Black, and younger donors. A new equation is needed to estimate postdonation renal function.
