The outcomes of transplantation have improved, but more than 50% of kidney transplantation (KT) recipients are still reported to have renal function of chronic kidney disease (CKD) stage 3 at 1 year after KT. We reviewed all 1235 patients who received a KT in our institution between 2008 and 2012. Among these recipients, 77 and 289 cases were included in the estimated glomerular filtration rate (eGFR) at 1 year after KT 30-44 (CKD stage 3b) group and eGFR 45-59 (CKD stage 3a) group, respectively. Longer duration of dialysis (odds ratio [OR] = 1.007, 95% confidence interval [CI], 1.000-1.014, P = 0.047), older donors (OR = 1.064, 95% CI, 1.031-1.098, P < 0.001), delayed graft function (OR = 3.601, 95% CI, 1.031-1.098, P < 0.001), BK virus infection (OR = 2.567, 95% CI, 1.242-5.305, P = 0.011), and pneumonia (OR = 4.451, 95% CI, 1.388-14.279, P = 0.012) were contributing factors to eGFR 30-44 mL/min. Especially, ureteral stricture occurred more frequently in eGFR 30-44 group of deceased donor KT. However, acute rejection was not a significant risk factor of lower eGFR. Graft survival was better in the eGFR 45-59 group. However, this difference was smaller in deceased donor KT. Infections and urologic complications are also important contributing factors of lower graft function in CKD stage 3. In addition, dividing CKD stage 3 into subgroups might be more useful in living donor kidney transplantation.
移植的效果已有改善,但仍有超过50%的肾移植(KT)受者在肾移植术后1年时被报告肾功能处于慢性肾脏病(CKD)3期。我们回顾了2008年至2012年期间在我院接受肾移植的所有1235例患者。在这些受者中,分别有77例和289例被纳入肾移植术后1年估算肾小球滤过率(eGFR)为30 - 44(CKD 3b期)组和eGFR 45 - 59(CKD 3a期)组。透析时间较长(比值比[OR]=1.007,95%置信区间[CI],1.000 - 1.014,P = 0.047)、供者年龄较大(OR = 1.064,95% CI,1.031 - 1.098,P < 0.001)、移植肾功能延迟(OR = 3.601,95% CI,1.031 - 1.098,P < 0.001)、BK病毒感染(OR = 2.567,95% CI,1.242 - 5.305,P = 0.011)以及肺炎(OR = 4.451,95% CI,1.388 - 14.279,P = 0.012)是eGFR为30 - 44 mL/min的影响因素。特别是,输尿管狭窄在死亡供者肾移植的eGFR 30 - 44组中更频繁发生。然而,急性排斥反应并非eGFR降低的显著危险因素。eGFR 45 - 59组的移植肾存活率更高。然而,在死亡供者肾移植中这种差异较小。感染和泌尿系统并发症也是CKD 3期移植肾功能降低的重要影响因素。此外,将CKD 3期分为亚组在活体供肾移植中可能更有用。
