Abstract

In 2015 the International Club of Ascites gave an accurate, exact and new definition of acute renal injury in cirrhotic patient, identifying objective criteria of severity and recoding hepatorenal syndrome as a particular form of renal dysfunction for which excessive renal vasoconstriction is one of the main, but not the only, pathophysiological mechanisms. In this review we tried to outline new pathophysiological and therapeutic insights, and to summarize the most recent recommendations. Vasopressor such as terlipressin and norepinephrine, in combination with albumin, still represent the first line therapy. However, the new discoveries in the pathophysiology of the disease have led the search for new pharmacological approaches, although, to date, the only definitive remedy is represented by liver (or simultaneous liver-kidney) transplantation.
