Therapeutic possibilities of gut microbiota modulation in acute decompensation of liver cirrhosis

World Journal of Hepatology 2023年第4期15卷 525-537页

The formation of liver cirrhosis(LC) is an unfavorable event in the natural history of chronic liver diseases and with the development of portal hypertension and/or impaired liver function can cause a fatal outcome. decompensation of LC is considered the most important stratification variable for the risk of death. It is currently postulated that decompensation of LC occurs through an acute(including acute-on-chronic liver failure) and non-acute pathway. acute decompensation of LC is accompanied by the development of life-threatening complications, characterized by an unfavorable prognosis and high *** in understanding the underlying molecular mechanisms has led to the search for new interventions, drugs, and biological substances that can affect key links in the pathogenesis of acute decompensation in LC, for example the impaired gut-liver axis and associated systemic inflammation. Given that particular alterations in the composition and function of gut microbiota play a crucial role here, the study of the therapeutic possibilities of its modulation has emerged as one of the top concerns in modern hepatology. This review summarized the investigations that describe the theoretical foundations and therapeutic potential of gut microbiota modulation in acute decompensation of LC. Despite the encouraging preliminary data, the majority of the suggested strategies have only been tested in animal models or in preliminary clinical trials;additional multicenter randomized controlled trials must demonstrate their efficacy in larger patient populations.

Patients with chronic liver diseases(CLDs)develop acute liver injury and/or acute decompensation under the attack of various precipitants and present with significantly elevated alanine aminotransferase and/or total bilirubin levels,liver failure,or acute decompensation of liver cirrhosis,which is called acute-on-CLD(AoCLD).AoCLD accounts for the majority of patients hospitalized in the Department of Hepatology or Infectious *** is complicated by various clinical types,the severity of the disease,and may pose a high risk of *** date,the definition of AoCLD is still vague,and a consensus concept of the clinical classification is *** review aimed to define the concept and clinical types of AoCLD based on related studies and the literature.
