ABSTRACT: Background
Patients with chronic kidney disease (CKD) have high cardiovascular mortality and morbidity associated with increased arterial stiffness. Plasma aldosterone levels are increased in CKD, and aldosterone has been found to increase vascular inflammation and fibrosis. It was hypothesized that aldosterone receptor inhibition with eplerenone could reduce arterial stiffness in CKD stage 3-4.Study design
The design was randomized, open, parallel group. Measurements of arterial stiffness markers were undertaken at weeks 1 and 24.Intervention
24 weeks of add-on treatment with 25-50 mg eplerenone or standard medication.Outcomes
Primary outcome parameter was carotid-femoral pulse wave velocity (cfPWV). Secondary outcomes were augmentation index (AIx), ambulatory arterial stiffness index (AASI) and urinary albumin excretion.Results
Fifty-four CKD patients (mean eGFR 36 mL/min/1.73 m(2), SD 11) were randomized. Forty-six patients completed the trial. The mean difference in cfPWV changes between groups was 0.1 m/s (95%CI: -1.0, 1.3), P?=?0.8. The mean difference in AIx changes between groups was 4.4% (0.1, 8.6), P?=?0.04. AASI was unchanged in both groups. The ratio of change in urinary albumin excretion in the eplerenone group compared to the control was 0.61 (0.37, 1.01), P?=?0.05. Four patients were withdrawn from the eplerenone group including three because of possible side effects; one was withdrawn from the control group. Mild hyperkalemia was seen on three occasions and was easily managed.Limitations
The full planned number of patients was not attained. The duration of the trial may have been too short to obtain full effect of eplerenone on the arteries.Conclusions
Add-on treatment with eplerenone in CKD stage 3-4 did not significantly reduce cfPWV. There may be beneficial vascular effects leading to attenuated pulse wave reflection. Treatment was well-tolerated.Trial registration
