Acute-On-Chronic Liver Failure ; diagnosis ; Humans

Acute-on-chronic liver failure (ACLF) is a form of complex syndrome with acute deterioration of liver function that occurs on the basis of chronic liver disease, and is accompanied by hepatic and extrahepatic organ failure with high mortality rate. The short-term mortality rate of comprehensive internal medicine treatment is as high as 50%-90%. This paper summarizes the current common definitions and diagnostic criteria, early-warning prediction models, and pathogenesis of ACLF.

Acute-on-chronic liver failure (ACLF) is a type of complex clinical syndrome that is mainly characterized by acute deterioration of liver function based on chronic liver disease, hepatic and extrahepatic organ failures, and a high short-term mortality rate. The comprehensive medical treatment efficacy of ACLF is currently limited; thus, liver transplantation is the only viable potential treatment method. However, considering the severe liver donor shortage, economic and social costs, as well as the differences in disease severity and prognosis of different disease courses, it is particularly important to accurately assess the benefits of liver transplantation in patients with ACLF. Early identification and prediction, timing, prognosis, and survival benefits are discussed here by combining the latest research findings so as to optimize the liver transplantation treatment strategy for ACLF.

In January 2022, the American College of Gastroenterology released its first clinical guidelines, integrating the latest research, summarizing the three current definitions characteristics, and proposing recommendations and core viewpoints with important clinical practice value to guide diagnosis, treatment, and management of acute-on-chronic liver failure. This article interprets and summarizes the highlights of the guideline, raises controversial issues, and suggests directions for future research.

Acute-on-chronic liver failure (ACLF) occurs in the presence of a chronic liver disease or cirrhosis, and often results from exacerbation of chronic hepatitis B (CHB). The efficacy of corticosteroid treatment in ACLF patients with underlying CHB remains unclear. We report the case of a 50-year-old woman who experienced ACLF due to CHB exacerbation and was treated with a combination of corticosteroids and nucleot(s)ide analogue (NUC). The patient showed rapid decompensation due to CHB exacerbation. Three months of antiviral therapy produced no improvement in liver function. Combination therapy with corticosteroids and NUC was started, which did result in improvement of liver function. This case shows that the combined therapy of corticosteroids and NUC can be effective in treating ACLF due to CHB exacerbation.

Acute-on-chronic liver failure (ACLF) is a clinical syndrome of acute decompensation accompanied by organ failure that occurs on the basis of chronic liver disease and has a high short-term mortality rate. Currently, there are still differences in relation to the definition of ACLF; thus, baseline characteristics and dynamic changes are important bases for clinical decision-making in patients with liver transplantation and others. The basic strategies for treating ACLF currently include internal medicine treatment, artificial liver support systems, and liver transplantation. Multidisciplinary active collaborative management throughout the whole course is of great significance for further improving the survival rate in patients with ACLF.

Acute-on-chronic liver failure (ACLF) is a potentially reversible entity that occurs in patients with chronic liver disease accompanied with or without cirrhosis and is characterized by extrahepatic organ failure and high short-term mortality. Currently, the most effective treatment method for patients with ACLF is liver transplantation; therefore, admission timing and contraindications must be emphasized. The function of vital organs such as the heart, brain, lungs, and kidneys should be actively supported and protected during the liver transplantation perioperative period in patients with ACLF. Focusing on the anesthesia management level during anesthesia selection, intraoperative monitoring, three-stage management, prevention and treatment of post-perfusion syndrome, monitoring and management of coagulation function, volume monitoring and management, and body temperature monitoring management for liver transplantation should strengthen anesthesia management. Additionally, standard postoperative intensive care treatment should be recommended, and grafts and other vital organ functions should be monitored throughout the perioperative period to promote early postoperative recovery in patients with ACLF.

Acute-on-chronic liver failure(ACLF) is the most severe form of acute decompensation that develops in patients with chronic liver disease or liver cirrhosis,and is always accompanied by one or more extrahepatic organ failure, and has an extremely poor short-term prognosis. The causes triggering ACLF are complex and diverse,and the clinical stage and the type and the definition of organ failure differ greatly from one another. Therefore, a universally accepted diagnostic criteria for ACLF is not to be defined, and the epidemiological data and patient outcomes on ACLF are not easy to predict and compare among different regions. Accumulating evidence has shown that liver transplantation(LT) plays a significant role in the surgical treatment of patients with ACLF,but its clinical value is still controversial. The specific management and treatment strategy after the admission of patients with ACLF has not yet formed a unified and standardized process or opinions, which includes the monitoring in the ICU,the support and maintenance of organ functions, the selection of the surgical indication and the timing for LT and so on. Moreover, there still exists many controversies concerning, for example, whether patients with ACLF should receive greater priority for organ allocation compared to other potential candidates on the waiting list. Besides, more prospective controlled studies are urgently needed to investigate the role of the artificial liver support system in the bridging therapy to LT. The aim of this article is to review the indication selection of patients with ACLF suitable for LT,the survival outcomes and prognostic factors after LT, the selection of timing, the organ allocation policy and the bridging therapy to LT, which intends to provide new direction for designing the future clinical studies on LT in patients with ACLF.

OBJECTIVETo compare the clinical values of the model for end-stage liver disease (MELD)-Na scoring system and the Child-Turcotte-Pugh (CTP) scoring system for predicting the short-term prognosis of acute-on-chronic hepatitis B liver failure.

METHODSA total of 339 patients with acute-on-chronic hepatitis B liver failure and admitted to the Eighth People's Hospital of Guangzhou and Nanfang Hospital of Southern Medical University between January 2010 and December 2012 were included in this retrospective analysis. The short-term predictive values of MELD-Na and CTP scores were compared for this patient population.

RESULTSThe mean MELD-Na score in the advanced stage of liver failure was significantly higher than those in the early and middle stages, respectively (both P less than 0.01). The mean MELD-Na score in the middle stage of liver failure was also significantly higher than that in the early stage (P less than 0.01). In contrast, the mean CTP scores for the three stages of liver failure were not significantly different (all P more than 0.05). The MELD-Na score showed a stronger correlation with the stage of liver failure (rs =0.485, P less than 0.01) than did the CTP score (rs =0.306, P less than 0.01). The short-term mortality rates were significantly different for the three stages of liver failure (P less than 0.01). The mean MELD-Na score of the death group was significantly higher than that of the survival group (P less than 0.01). The CTP scores, however, were not significantly different between the death and survival groups (P more than 0.05).The short-term mortality rate of liver failure was significantly higher for patients with increased scores for the MELD-Na and CTP systems (both P less than 0.01). The areas under the curve of the MELD-Na and CTP scores were 0.813 and 0.823, respectively. The MELD-Na and CTP score have similar predictive values (P more than 0.05).

CONCLUSIONThe MELD-Na scoring system is slightly superior to the CTP scoring system for predicting short-term prognosis of acute-on-chronic hepatitis B liver failure.The predictive value may improve for both the MELD-Na score and the CTP score when combined with expert clinical practice and experience.
