Core Tip

Core tip: Acute kidney injury (AKI) is frequently observed in hospitalized patients with cirrhosis and is associated with increased mortality. Recently a new definition for AKI has been proposed by the International Club of Ascites in order to allow early diagnosis and management of AKI in cirrhosis with the purpose of reducing its mortality, particularly with the occurrence of hepatorenal syndrome.
