title: Uremic toxins in acute kidney injury.
abstract: Acute kidney injury (AKI) is a serious and frequent condition which may fully resolve but is associated with markedly increased mortality. Mortality in AKI is caused by nonrenal, distant organ failure. Renal recovery from AKI is often not achieved on account of new injuries in the repair phase. Uremic toxins may be the missing link between AKI and nonrenal organ failure, tubular and endothelial injury. Compared with chronic kidney disease (CKD), research of uremic toxins in AKI is in its infancy. This review presents the current knowledge on uremic toxins in AKI which is predominately derived from experimental studies. Most uremic toxins investigated have previously been identified in CKD. The review focuses on those uremic toxins with biologic effect on the respective nonrenal organs failing in AKI and on the renal tubule and the endothelium. These uremic toxins may insofar be specific mediators of pathophysiological processes in AKI.
