Acute kidney injury in patients with decompensated cirrhosis: knowing the cause is often difficult

Mohammed Faisal Rahman, Harold M. Szerlip


Acute renal failure (AKI), which occurs in up to 20–50% of patients hospitalized with decompensated cirrhosis is an important predictor of poor outcomes and mortality (1,2). The etiology of AKI in these patients has been divided into a functional decrease in renal function; as is in pre-renal azotemia (PRA) and Hepato-renal syndrome (HRS) or structural abnormalities as is in acute tubular necrosis (ATN).
