New drugs on the horizon for acute kidney injury

Abstract

Purpose of review Acute kidney injury (AKI) is a frequent and serious complication in critically ill patients. Currently, no effective therapy to prevent or treat AKI is available. This review highlights recently published developments on pharmacological treatments that aim to prevent AKI or to alleviate the severity of AKI in critical ill patients. Recent findings Studies on pharmacological interventions aimed to improve hemodynamics, renal perfusion, to mediate inflammation-associated renal damage and to reduce oxidative stress are presented, including several observational studies and randomized trials focused on the potential renal protective effects in relevant patient populations. Different existing and novel compounds are being investigated for the effects on renal endpoints and several show potential to prevent or alleviate the occurrence of AKI. It is now ac knowledged that different underlying pathophysiological processes are relevant in the development of AKI. Recognition of these sub-endotypes of AKI and knowledge of the therapeutic target of different compounds is of paramount importance to select the right patient for the right treatment at the right time. Summary The discovery of reno-protective therapies is hampered by the timely detection and recognition of the overriding mechanism of AKI. Nevertheless, several compounds are under investigation, which hold promise for a future treatment.
