- Abstract
Evidence supports the use of angiotensin-converting enzyme inhibitors (ACEis) and angiotensin-receptor blockers (ARBs) in patients with hypertension and stage 3 or milder chronic kidney disease (CKD). This systematic review and individual-level meta-analysis summarizes the evidence supporting the use of the medications in patients with hypertension and more advanced CKD. Background: In patients with advanced chronic kidney disease (CKD), the effects of initiating treatment with an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin-receptor blocker (ARB) on the risk for kidney failure with replacement therapy (KFRT) and death remain unclear. Purpose: To examine the association of ACEi or ARB treatment initiation, relative to a non–ACEi or ARB comparator, with rates of KFRT and death. Data Sources: Ovid Medline and the Chronic Kidney Disease Epidemiology Collaboration Clinical Trials Consortium from 1946 through 31 December 2023. Study Selection: Completed randomized controlled trials testing either an ACEi or an ARB versus a comparator (placebo or antihypertensive drugs other than ACEi or ARB) that included patients with a baseline estimated glomerular filtration rate (eGFR) below 30 mL/min/1.73 m 2. Data Extraction: The primary outcome was KFRT, and the secondary outcome was death before KFRT. Analyses were done using Cox proportional hazards models according to the intention-to-treat principle. Prespecified subgroup analyses were done according to baseline age (<65 vs. ≥65 years), eGFR (<20 vs. ≥20 mL/min/1.73 m 2), albuminuria (urine albumin–creatinine ratio <300 vs. ≥300 mg/g), and history of diabetes. Data Synthesis: A total of 1739 participants from 18 trials were included, with a mean age of 54.9 years and mean eGFR of 22.2 mL/min/1.73 m 2 , of whom 624 (35.9%) developed KFRT and 133 (7.6%) died during a median follow-up of 34 months (IQR, 19 to 40 months). Overall, ACEi or ARB treatment initiation led to lower risk for KFRT (adjusted hazard ratio, 0.66 [95% CI, 0.55 to 0.79]) but not death (hazard ratio, 0.86 [CI, 0.58 to 1.28]). There was no statistically significant interaction between ACEi or ARB treatment and age, eGFR, albuminuria, or diabetes (P for interaction > 0.05 for all). Limitation: Individual participant–level data for hyperkalemia or acute kidney injury were not available. Conclusion: Initiation of ACEi or ARB therapy protects against KFRT, but not death, in people with advanced CKD. Primary Funding Source: National Institutes of Health. (PROSPERO: CRD42022307589)
