Albert C, et al. - In this study, the biomarker-specific outcome patterns and short-and long-term prognosis of CS-AKI (acute kidney injury) identified by standard criteria and/or urinary kidney-biomarkers were determined. Researchers noticed that urinary kidney-biomarkers identified Risk Injury Failure Loss and End-stage (RIFLE)-negative patients with high-risk subclinical-AKI as well as a higher risk-subgroup of patients among RIFLE-AKI-positive patients. Findings thereby supported the concept that among standard AKI patients, urinary biomarkers define subclinical-AKI and higher risk subpopulations with worse long-term prognosis.
