Incidence, risk factors and outcomes of acute kidney injury (AKI) in patients with acute-on-chronic liver failure (ACLF) of underlying cirrhosis

Background and aims Acute kidney injury (AKI) is a life-threatening complication in patients with acute-on-chronic liver failure (ACLF) of underlying cirrhosis. However, the characteristics of AKI in these patients have not been clarified. Our aim was to determine the incidence and risk factors of AKI and the association between AKI severity and 180-day transplant-free survival.
