ReviewHypoxic liver injury and cholestasis in critically ill patients.
Liver dysfunction frequently complicates the clinical picture of critical illness and leads to increased morbidity and mortality. The purpose of this review is to characterize the most frequent patterns of liver dysfunction at the intensive care unit, cholestasis and hypoxic liver injury (HLI), and to illustrate its clinical impact on outcome in critically ill patients. ⋯ Clinical awareness of the liver not only as a victim, but also as a trigger of multiorgan failure is of central clinical importance. Physicians have to identify the underlying factors that contribute to its development to initiate curative measures as early as possible.

This review will summarize the recent advances in our understanding of the relationship between liver and kidney function. It will outline the new concepts of the pathophysiology of renal dysfunction in chronic liver disease and examine novel renal biomarkers to detect acute kidney injury (AKI) in cirrhosis and following liver transplantation. We will further review new treatments for hepatorenal syndrome (HRS) and approaches to kidney dysfunction in liver transplantation recipients. ⋯ Greater knowledge of the physiologic relationship between kidney and liver may open avenues for specific therapies of liver and kidney injury. Renal biomarkers may allow early diagnosis and targeted treatment of AKI, and improved management of kidney disease in the preliver and postliver transplantation setting will be crucial to improving long-term outcomes in these patients.
