BackgroundThere is recent evidence to show that patients suffering from acute kidney injury are at increased risk of developing chronic kidney disease despite the fact that surviving tubular epithelial cells have the capacity to fully regenerate renal tubules and restore renal function within days or weeks. The aim of the study was to investigate the impact of acute kidney injury on de novo chronic kidney disease.MethodsThe authors conducted a retrospective population-based cohort study of patients initially free from chronic kidney disease who were scheduled for elective cardiac surgery with cardiopulmonary bypass and who developed an episode of acute kidney injury from which they recovered. The study was conducted at two French university hospitals between 2005 and 2015. These individuals were matched with patients without acute kidney injury according to a propensity score for developing acute kidney injury.ResultsAmong the 4,791 patients meeting the authors' inclusion criteria, 1,375 (29%) developed acute kidney injury and 685 fully recovered. Propensity score matching was used to balance the distribution of covariates between acute kidney injury and non- acute kidney injury control patients. Matching was possible for 597 cases. During follow-up, 34 (5.7%) had reached a diagnosis of chronic kidney disease as opposed to 17 (2.8%) in the control population (hazard ratio, 2.3; bootstrapping 95% CI, 1.9 to 2.6).ConclusionsThe authors' data consolidate the recent paradigm shift, reporting acute kidney injury as a strong risk factor for the rapid development of chronic kidney disease.
