Dear Editor,
Acute kidney injury (AKI) is a common clinical entity in critical care and perioperative settings. [1],[2] Most of the current diagnostic modalities are based on serum creatinine. However, it is an imperfect tool for diagnosis of AKI in the elderly population who has poor muscle mass. Often the diagnosis is too late, and irreparable damage is already done. As such a continual need is felt to devise and search newer diagnostic modalities for early diagnostic and therapeutic intervention. The emphasis is primarily on minimizing the morbidity and mortality associated with AKI by early diagnosis and management.
In recently published articles, the need for newer biomarkers for early diagnosis and management of AKI has been emphasized. [3],[4] Food and Drug Administration has recently approved Nephrocheck as a diagnostic tool for early diagnosis of AKI. It is based on bioassay of two biomarkers. One of the marker being tissue inhibitor of metalloproteinases-2 (TIMP), and the other one is insulin-like growth factor binding protein 7 (IGFBP-7). Both are related to G1 cell cycle arrest during mitosis in cell replication. Bihorac et al. in a recent trial validated both these biomarkers as a diagnostic tool for AKI. [5] In a prospective multicenter study 420 patients were studied with the objective to analyze these two biomarkers for diagnosis of AKI within 12 h. The cut-off value was set at 0.3 for AKI. Immunoassay was used to measure urinary TIMP-2 and IGFBP-7. Both the biomarkers were strong predictors of AKI.
This is a big step forward in the management of AKI, which is associated high morbidity and mortality. [6],[7] More data are likely to be available in coming years as the tests get incorporated into clinical practice. This should help in improving outcomes and reducing the cost to the health budget and society.
