JASN:血管紧张素转换酶抑制剂降低蛋白尿可预测CKD患儿肾脏存活情况

2018-07-02 xing.T MedSci原创

由此可见,ACE抑制剂的早期抗蛋白尿作用与CKD患儿长期保留的肾功能有关。蛋白尿降低应该被认为是儿科CKD治疗的重要目标。

尽管药物治疗性蛋白尿降低被发现在成人中具有肾保护作用,但儿童慢性肾病的早期药物诱导的蛋白尿降低对长期肾脏存活的预测价值尚不清楚。近日,肾脏病领域权威杂志Journal of the American Society of Nephrology上发表一篇研究文章,研究人员从ESCAPE试验中分析了慢性肾病患儿标准化血管紧张素转换酶(ACE)抑制的初始抗蛋白尿效应与肾病进展之间的潜在关联。

该研究总共纳入了280例符合条件的CKD 2-4期患儿(平均年龄为11.7岁,中位eGFR为46ml/min/1.73m2,71%患有先天性肾脏畸形),这些患儿接受固定剂量的雷米普利(6mg/m2/d)治疗,随后随机接受常规或强化血压控制。研究人员评估了初始蛋白尿从基线到服用雷米普利后第一次测量(2.5±1.3个月)的降低情况。研究人员使用多变量Cox建模来评估初始蛋白尿减少与达到肾功能终点(eGFR下降50%或ESRD)风险之间的关联,在5年观察期间有80名患者发生肾功能终点事件。

雷米普利治疗使蛋白尿降低了43.5%(95%可信区间为36.3%-49.9%)。相对于蛋白尿减少<30%,蛋白尿降低30%-60%和>60%导致风险比(95%可信区间)分别为0.70(0.40-1.22)和0.42(0.22-0.79)。这种关联与年龄、性别、CKD诊断、基线eGFR、基线蛋白尿、初始血压和伴随血压降低无关。

由此可见,ACE抑制剂的早期抗蛋白尿作用与CKD患儿长期保留的肾功能有关。蛋白尿降低应该被认为是儿科CKD治疗的重要目标。
