KIDNEY INT:蛋白尿和肾脏移植后慢性肾脏病阶段预测移植结局!

2017-04-01 xing.T MedSci原创

肾移植接受者eGFR降低或蛋白尿较严重与死亡和移植物损失的风险增加相关。因此,eGFR和蛋白尿可以被用来识别、评估和管理临床预后不良风险较高的移植接受者。

2012年,KDIGO指南更新了慢性肾脏病包括蛋白尿在内的分类系统。这种分类系统是否能够预测肾移植受者的不良临床结局尚不清楚。为了评估这一点,近日,肾脏病领域权威杂志kidney international上发表了一篇研究文章,研究人员在加拿大阿尔伯塔进行了一项回顾性研究,通过连接2002年至2011年期间肾移植接受者随访数据库。

研究人员评估了移植后一年估计肾小球滤过率(eGFR>60,45-59,30-44,15-29ml/min/1.73m2)和蛋白尿(正常、轻、重)与随后的死亡和移植物损失之间的相关性。该研究有900例肾功能移植患者,并且移植1年至少进行过一次门诊血清肌酐和尿蛋白测定。

这些参与者中位年龄为51.2岁,女性为38.7%,eGFR为60 ml/min/1.73m2或更大。研究人员发现在eGFR降低或蛋白尿较严重的参与者中全因死亡率和死亡确认的移植物损失的风险增加。对于eGFR 15-29 ml/min/1.73m2以及大量蛋白尿的参与者比上eGFR超过60 ml/min/1.73m2并且蛋白排泄率正常的参与者,其调整后的全因死亡发生率分别为每1000人每年117例(95%可信区间38-371)和15例(9-23)(比值比为8)。对应的死亡确认的移植物损失发生率分别为273例(88-1203)和6例(3-9)(比值比为49)。

肾移植接受者eGFR降低或蛋白尿较严重与死亡和移植物损失的风险增加相关。因此,eGFR和蛋白尿可以被用来识别、评估和管理临床预后不良风险较高的移植接受者。
