- Abstract
Individuals with liver disease are susceptible to pathophysiological derangements that lead to kidney dysfunction. Patients with advanced cirrhosis and acute liver failure (ALF) are at risk of developing acute kidney injury (AKI). Hepatorenal syndrome type 1 (HRS-1, also called HRS-AKI) constitutes a form of AKI unique to the state of cirrhosis and portal hypertension. Although HRS-1 is a condition primarily characterized by marked renal vasoconstriction and kidney hypoperfusion, other pathogenic processes, such as acute tubular injury and renal vein congestion, can overlap and further complicate the course of HRS-1. ALF can lead to AKI through mechanisms that involve systemic inflammation, direct drug toxicity, or bile acid-induced tubulopathy. In addition, the growing prevalence of nonalcoholic steatohepatitis is changing the spectrum of chronic kidney disease in cirrhosis. In this installment of AJKD's Core Curriculum in Nephrology, we explore the underpinnings of how cirrhosis, ALF, acute cholestasis, and post-liver transplantation can be associated with various forms of acute, subacute, or chronic kidney diseases. We navigate through the recommended therapies for each condition, including supportive care, pharmacological interventions, kidney replacement therapy, and organ transplantation. Finally, key acid-base and electrolyte disorders associated with hepatobiliary disease are also summarized., (Copyright © 2023 National Kidney Foundation, Inc. Published by Elsevier Inc.
