[Progress in clinical research on potential therapeutic drugs for acute-on-chronic liver failure].

Acute-on-chronic liver failure (ACLF), has a high mortality rate and a poor prognosis. Currently, the only effective treatment for ACLF is liver transplantation. However, the number of patients who can successfully undergo liver transplantation is limited due to the rapid progression of ACLF, the occurrence of serious complications, and a dearth of liver donors. The available drug treatment indication expansion and pathogenesis exploration are expected to delay the progression of ACLF, reduce complications, and provide patients with opportunities for liver transplantation by improving portal vein pressure, inhibiting excessive inflammatory response, correcting energy metabolism disorders, reducing oxidative stress, resisting hepatic cell apoptosis, and promoting liver regeneration.
