CPB:使用速尿不会导致肾病综合征大量蛋白尿所致的肾小管上皮细胞损伤加重

2021-09-15 从医路漫漫 MedSci原创

大量蛋白尿是肾病综合征(NS)的重要标志,有可能损害肾小管上皮细胞(TECs)。速尿被广泛用于治疗水肿,水肿NS的一种常见的临床表现。

目的:大量蛋白尿是肾病综合征(NS)的重要标志,有可能损害肾小管上皮细胞(TECs)。速尿被广泛用于治疗水肿,水肿NS的一种常见的临床表现。然而,速尿治疗是否影响NS患者的大量蛋白尿引起TEC损伤尚不清楚。

方法:体外观察速尿对TEC损伤的影响。此外,还进行了一项临床研究,以研究速尿短期治疗肾病水肿是否会加重TEC的损伤。

结果:暴露于大量尿蛋白(8mg/mL)的体外人肾-2(HK-2)细胞的增殖显着降低(P<0.05),而肾损伤分子-1(Kim-1)和嗜中性粒细胞明胶酶相关脂质运载蛋白(NGAL)在上清液中显着增加(P<0.05)。重要的是,呋塞米治疗并未进一步增加由大量蛋白尿上调的HK-2细胞中Kim-1和NGAL的表达。在临床研究中,26例NS患者随机分为两组,均服用推荐剂量的泼尼松(1 mg/kg/d)。,其中一组(n=13)接受速尿(60-120 mg/d,静脉注射)治疗1周,其余患者(对照组)不接受速尿或任何其他利尿剂治疗。结果表明,速尿治疗组24h尿量略高于对照组,但差异不显著(P>0.05)。此外,两组患者血清BUN、Scr、CysC、尿Kim-1、NGAL水平均无显著性差异(P均>0.05)。23名患者接受了肾活检。其中22例为TECs空泡变性,8例为刷状缘膜脱落,12例为蛋白管型。两组比较差异无统计学意义(均P>0.05)。

图1 速尿对肾病综合征患者尿量的影响。治疗后0d、1d、2d、3d、4d、5d、6d、7d患者24h尿量的变化。数据以均值±SEM表示,两组比较用重复测量数据方差分析计算,*P<0.05,与0天比较。

图2 速尿对慢性肾功能不全患者肾功能的影响。(A、B、C)患者治疗0、3、7d后血尿素氮(BUN)、血清肌酐(Scr)、胱抑素C(CysC)水平的变化。(D、E)治疗0、3、7d后尿中Kim-1、NGAL水平的变化。

数据用均值±SEM表示,使用重复测量数据方差分析计算两组比较。

表1 观察治疗后患者肾脏病理变化。数据用计数(Number)表示,用Wilcoxon秩和检验计算组间差异的P值。

MCNs:微小病变型肾病综合征;FSGS:局灶性节段性肾小球硬化;MN:膜性肾病;MsPGN:

图3 肾病综合征患者发生肾小管上皮细胞损伤。(A)肾小管上皮细胞的空泡化(箭头),PASM*400;(B)刷状缘膜脱落(箭头)和肾小管上皮细胞的蛋白管型(星号),PASM*400。

结论:大量蛋白尿可导致NS患者TECs损伤,速尿治疗不会加重这种损伤。

Hypertension:肾病综合征患者的足细胞损伤促进Ang II的合成和钠水潴留

Masahiro Koizumi等人既往发现足细胞损伤科增加肝源性Agt(血管紧张素原)的肾小球滤过率和肾内Ang II(血管紧张素II)的生成,滤过的Agt被近端小管以megalin依赖性方式重吸收。本研究对megalin在肾病综合征过程中肾Ang II的产生和钠处理中的作用进行研究。研究人员建立一个近端小管megalin特异性敲除的小鼠,并将这些KO小鼠与NEP25小鼠进行杂交;NEP25小鼠
