Renal dysfunction causes significant morbidity in cirrhotic patients. Diagnosis is challenging because it is based on serum creatinine, which is used to calculate estimated glomerular filtration rate, which itself is not an ideal measure of renal function in patients with cirrhosis. Finding the exact cause of renal injury in patients with cirrhosis remains problematic due to the limitations of the current diagnostic tests. The purpose of this review is to highlight studies used to diagnose renal dysfunction in patients with renal dysfunction and review current treatments. ⋯ Development of new biomarkers to differentiate the different types of AKI in cirrhosis holds promise. Early intervention in cirrhotic patients with renal dysfunction offers the best hope of improving outcomes.

Acute liver failure (ALF) is a rare but life-threatening systemic disorder. Survival rates with or without emergency liver transplantation (ELT) are increasing. The benefit of ELT in some cases has been questioned and the potential for survival with medical management alone is changing our approach to the management of this disease. ⋯ ALF remains a life-threatening condition with a high mortality rate requiring prompt support of multiorgan failure. Historical listing criteria for ELT are being questioned and improvement in medical management offers the option of continued improvements in transplant-free survival.
