Biomarkers of Acute Kidney Injury Following Cardiac Surgery
Biomarkers of Acute Kidney Injury Following Cardiopulmonary Bypass Surgery-supported Cardiac Surgery
Study Overview
Status
Detailed Description
Cardiopulmonary bypass (CPB), although essential to the performance of most cardiac operations, has been shown to cause injury to other organs, particularly to the kidneys and brain. Matrix Metalloproteins (MMPs) are ubiquitous proteolytic enzymes that degrade extracellular matrix and have been shown to be involved in injury to transplant kidneys. To date, no interventions are available to decrease the risk of cardiac surgery associated-acute kidney injury (CSA-AKI).
NGAL is a known indicator of injury to kidney, thus making it a promising biomarker for CSA-AKI. It may be that a single biomarker will not be sensitive and specific across the spectrum of CSA-AKI. This research investigates MMP-2, -9 and Neutrophil gelatinase-associated lipocalin (NGAL) and their association with and earlier detection of CSA-AKI compared to levels of SCr.
We hypothesize that increased activity of MMPs are associated with CSA-AKI. Furthermore, MMP-2 and/ or -9 may be predictors and/ or biomarkers for the early detection of CSA-AKI compared to serum levels of creatinine.
