PURPOSE OF REVIEW: Although recovery of kidney function following acute kidney injury (AKI) is not uncommon, it is often incomplete and associated with the development of chronic kidney disease (CKD). In order to improve AKI management, there is a critical need to develop a series of tests and biomarkers to detect renal function recovery and identify patients with progressive kidney disease. This article examines the current body of literature in the field.
RECENT FINDINGS: The recently established consensus definition for AKI has resulted in significant advances in pathophysiologic understanding, patient identification, and disease prognostication. Unfortunately, the definition for renal recovery following AKI remains inconsistent. Proteinuria and microalbuminuria - classical markers of CKD progression - have been used and validated for the progression of AKI to CKD. Data on the performance of other biomarkers of kidney repair and the progression toward CKD are very limited. Specifically, the role of novel biomarkers including neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, and nephronectin (NPNT) in the recovery process has been studied, but it has not reached the point of widespread clinical implementation.
SUMMARY: There is a critical need for translational and clinical investigations to verify the performance of potential kidney injury repair and progression biomarker candidates in the clinical setting.
