In certain conditions, such as during sepsis or after cardiac surgery, AKI is one of the most frequent complications, affecting 30%–50% of patients. Over time, even after the resolution of AKI, it can evolve into chronic kidney disease, a leading global cause of mortality, and cardiovascular complications. Despite significant improvement in the care of critically ill patients over the past two decades, the incidence of AKI remains stable, and novel approaches aiming at reducing its occurrence or improving AKI outcomes are still mostly lacking. However, recent insights into the pathophysiology of AKI within critical care settings have shed light on new pathways for both prevention and treatment, providing various new therapeutic targets aimed to mitigating kidney injury. These advancements highlight the intricate and multifaceted nature of the mechanisms underlying AKI, which could explain the challenge of identifying an effective treatment. Among these targets, modulation of the inflammatory responses and the cellular metabolism, hemodynamic regulation and enhancement of cellular repair mechanisms, have emerged as promising options. These multifaceted approaches offer renewed hope for limiting the incidence and severity of AKI in critically ill patients. Several ongoing clinical trials are evaluating the efficacy of these different strategies and we are facing an exiting time with multiple therapeutic interventions being tested to prevent or treat AKI.

When administered intravenously, they exhibit poor lung penetration and high systemic renal and ototoxicity, imposing to restrict their administration to 5 days. Experimental studies conducted in anesthetized and mechanically ventilated sheep and pigs provide evidence that high doses of nebulized aminoglycosides induce a rapid and potent bacterial killing in the infected lung parenchyma. They also confirm that the alveolar-capillary membrane, either normal or injured by the infectious process, restricts the penetration of intravenous aminoglycosides in the infected lung parenchyma, precluding a bactericidal effect at the site of infection. However, injury of the alveolar-capillary membrane promotes the systemic diffusion of nebulized aminoglycosides. Based on experimental data obtained in animals with inoculation pneumonia, it challenges the classical belief that nebulization protects against systemic toxicity. Loss of lung aeration decreases the lung penetration of nebulized aminoglycosides. Nevertheless, lung tissue concentrations measured in non-aerated lung regions with severe and extended pneumonia are most often greater than 5 times the MICs, resulting in a bactericidal effect followed by a progressive pulmonary reaeration. It is likely that the penetration into the consolidated lung, results from the bronchial diffusion of nebulized aminoglycosides toward adjacent non-aerated infected alveolar spaces and their penetration into mechanical ventilation-induced intraparenchymal pseudocysts and distended bronchioles. In animals receiving nebulized aminoglycosides, epithelial lining fluid concentrations grossly overestimate lung interstitial fluid concentrations because of the bronchial contamination of the distal tip of the bronchoscope during the bronchoalveolar procedures.
