Development and patterns of acute-on-chronic liver failure in patients with cirrhosis and acute kidney injury

This study highlights the significant risk of acute-on-chronic liver failure development in patients with cirrhosis and acute kidney injury (AKI), particularly in those with hepatorenal syndrome-AKI or other/mixed types of AKI. Given the high short-term mortality observed, early recognition and risk stratification of AKI in cirrhosis are crucial. These findings are particularly relevant for hepatologists, nephrologists, and intensivists, as they underscore the need for improved therapeutic strategies targeting AKI non-responders. Future prospective studies should not only explore targeted interventions to improve outcomes in this high-risk population but also aim to elucidate the underlying pathophysiology driving AKI progression and acute-on-chronic liver failure development in patients with cirrhosis and AKI.
