Abstract
Background
In recent years, a large amount of clinical evidence and animal experiments have demonstrated the unique advantages of mineralocorticoid receptor antagonists (MRA) for treating chronic kidney disease (CKD).
Aims
Accordingly, the present study aimed to systematically assess the second-generation selective MRAs eplerenone's safety and effectiveness for treating CKD.
Methods
Four databases (PubMed, The Cochrane Library, Embase, and Web of Science) were searched for randomized controlled trials (RCT) correlated with eplerenone for treating CKD up to September 21, 2022. By complying with the inclusion and exclusion criteria, literature screening, and data extraction were conducted.
Results
A total of 19 randomized controlled articles involving 4501 cases were covered. As suggested from the meta-analysis, significant differences were reported with the 24-h urine protein (MD = -42.23, 95% confidence interval [CI] = -76.72 to -7.73, P = 0.02), urinary albumin-creatinine ratio (UACR) (MD = -23.57, 95% CI = -29.28 to -17.86, P < 0.00001), the systolic blood pressure (SBP) (MD = -2.73, 95% CI = -4.86 to -0.59, P = 0.01), and eGFR (MD = -1.56, 95% CI = -2.78 to -0.34, P = 0.01) in the subgroup of eplerenone vs placebo. The subgroups of eplerenone vs placebo (MD = 0.13, 95% CI = 0.07 to 0.18, P < 0.00001) and eplerenone vs thiazide diuretic (MD = 0.18, 95% CI = 0.13 to 0.23, P < 0.00001) showed the significantly increased potassium levels. However, no statistical significance was reported between the eplerenone treatment groups and the control in the effect exerted by serum creatinine (MD=0.03, 95% CI = -0.01 to 0.07, P = 0.12) and diastolic blood pressure (DBP) (MD = 0.11, 95% CI = -0.41 to 0.63, P = 0.68). Furthermore, significant risks of hyperkalemia were reported in the eplerenone group (K+ ≥ 5.5 mmol/l, RR = 1.70, 95%CI = 1.35 to 2.13, P=<0.00001; K+≥6.0 mmol/l, RR = 1.61, 95% CIs = 1.06 to 2.44, P = 0.02), respectively.
Conclusions
Eplerenone has beneficial effects on CKD by reducing urinary protein and the systolic blood pressure, but it also elevates the risk of hyperkalemia.
