Insights
The inhibition of the renin-angiotensin-aldosterone (RAA) axis is debated for chronic kidney disease (CKD) progression. Recent studies question the benefits of angiotensin converting enzyme (ACE) inhibitors in delaying dialysis.
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Pharmacology
Background:
- The renin-angiotensin-aldosterone (RAA) axis inhibition was standard for progressive chronic kidney disease (CKD).
- The goal was to slow progression to end-stage renal disease (ESRD).
- Recent meta-analyses and studies in diabetic patients challenge the efficacy of angiotensin converting enzyme (ACE) inhibition in delaying dialysis.
Purpose of the Study:
- To critically review the ongoing debate on the role of RAA axis inhibition in CKD progression.
- To discuss the pros and cons of pharmacological interventions in managing CKD.
- To provide a cautious perspective for nephrologists regarding ACE inhibitor use in CKD.
Main Methods:
- Literature review and critical analysis of recent studies and meta-analyses.
- Discussion of conflicting data regarding ACE inhibition in CKD.
- Examination of potential overlooked factors in renal protection studies.
Main Results:
- Recent data raise questions about the established role of ACE inhibition in delaying dialysis in CKD patients.
- An intensive debate exists among nephrologists regarding the benefits and drawbacks of ACE inhibitors.
- Factors like central blood pressure, ambulatory blood pressure monitoring, and stroke risk may be crucial.
Conclusions:
- A cautious approach is recommended for practicing nephrologists.
- The distinction between clinical trial populations and real-world patients is important.
- Re-evaluation of ACE inhibitor therapy in CKD may be necessary, considering broader cardiovascular and hemodynamic parameters.
Abstract:
For a long time, the inhibition of the renin-angiotensin-aldosterone (RAA) axis has been considered a must in almost all patients with progressive chronic kidney disease (CKD), with the aim of reducing the rate of progression to end-stage renal disease (ESRD). However, recent data from a meta-analysis, including the ALLHAT study, and a study in Canadian diabetic patients questioned the usefulness of angiotensin converting enzyme (ACE) inhibition in delaying the onset of dialysis. Publication of these data led to an intensive recent debate among reputed nephrologists, with numerous pros and cons regarding the pharmacological influence of CKD progression. The authors of the present review critically discuss the arguments and counterarguments of this challenging debate. Finally, a cautious view for the practicing nephrologist is expressed, highlighting the difference between study patients and real-life patients, and the possible overlooked aspects of recent renal protection studies (the importance of central blood pressure, of ambulatory blood pressure monitoring and possible, the impact of angiotensin converting inhibitors on stroke), are presented.
