Outcomes and renal function trajectory after acute kidney injury: the narrow road to perdition.

Abstract

Analyses of the Grampian Laboratory Outcomes Morbidity and Mortality Study-II cohort support the notion that acute kidney injury (AKI) increases the risk of progression of glomerular filtration rate after recovery from AKI to a new baseline. However, the findings have to be considered in the bigger context of the absolute event rates for de novo progression versus nonrecovery and the competing risk of death after AKI. Examination of the data raises important implications for the design and implementation of clinical trials with interventions that target the AKI-to-chronic kidney disease transition.
