Exploring the interaction between bile acid and intestinal microbiota in acute-on-chronic liver failure and the progress of treatment strategies

Acute-on-Chronic Liver Failure (ACLF) is an acute and severe disease involving single or multiple organ failure. Due to the unclear pathogenesis, there is still a lack of effective drug treatment. Intestinal microbiota is closely related to Bile Acid (BA) metabolism. In the progression of chronic liver disease to ACLF, BA metabolism disorder is often accompanied by intestinal microbiota imbalance, which affect one another mutually. This article reviewed the role of BA metabolism and intestinal microbiota in the progression of ACLF, which aims to explore potential new targets for the treatment of ACLF.
