title: Current dilemmas in inhibiting the renin-angiotensin system: do not forget real life.
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.
