AbstractIn order to prevent a disease, its temporal nature (or at least when it starts) needs to be clearly defined. In acute kidney injury (AKI), this is usually not possible because the current diagnostic criteria are retrospective. Contrast-induced nephropathy (CIN) and cardiac surgery-associated acute kidney injury (CSA-AKI) are both thought of as potentially preventable acute renal lesions because the timing of the insult is known precisely. While this is true, knowledge of the exact biological processes that give rise to each condition is lacking, although there are several common themes - notably ischemia - that pervade the literature describing these diseases. Despite this, progress in prevention has been slow, and to date there are no therapies indicated for preventing either CIN or CSA-AKI. The best we can currently do is to recommend aggressive parenteral hydration, avoid compounds we know are nephrotoxic, and avoid unnecessary hypoxia and hypotension. While there is still clearly a long way to go before either of these acute kidney conditions can be described as preventable, the use of major adverse kidney events - death, dialysis and incident or progressive chronic kidney disease at 90 days - as a composite endpoint in clinical trials of putative prevention agents would represent a significant step forwards.Copyright © 2011 S.
