目的:目前的证据显示,醛固酮过剩会通过各种途径引起肾小球和肾小管间质炎症和纤维化。而盐皮质激素受体拮抗剂(MRA)在CKD进展中的影响尚不清楚。

结果:结合血管紧张素转化酶抑制剂(ACEI)或血管紧张素受体阻断剂(ARB)使用的MRAs可进一步降低蛋白尿和血压。MRAs作为疾病修饰疗法治疗CKD因肾功能恶化和高钾血症而受到限制。近期有一些小型研究认为,使用这类药物不必担忧高钾血症。此外,高钾血症不在是安全隐患时,这些药物还可以进一步降低血压。新型MRAs已经在3期临床试验中得到讨论。

小结:在与其他肾素-血管紧张素系统阻断剂联合使用时,MRAs进一步降低蛋白尿的效果非常明显;但是,高钾血症是MRAs类新药物使用的一个限制因素。新型钾粘结剂促进了MRAs在CKD中的使用,新型非甾类MRAs正在进行晚期CKD结局的试验。
