RESEARCH PROGRESS on the ROLE of GUT MICROBIOTA and ITS METABOLITES in the OCCURRENCE and DEVELOPMENT of SEPTIC-ASSOCIATED LIVER INJURY

Abstract

Sepsis is a life-threatening organ dysfunction that occurs due to a dysregulated host response to infection. Septic-associated liver injury (SALI) has been closely linked to the prognosis and mortality of sepsis. Recent investigations have delved into the gut-liver axis and its association with SALI, identifying its pivotal role in the gut microbiota. Bacterial translocation and the onset of SALI can occur due to an imbalance in the gut microbiota, impairing the function of the gut barrier. Moreover, their metabolites might exacerbate or initiate SALI by modulating immune responses. Nevertheless, interventions to restore the balance of the gut microbiota, such as the administration of probiotics, fecal microbiota transplantation, or dietary adjustments, may ameliorate SALI and enhance the prognosis and survival rates of septic patients. This review aimed to elucidate the function of the gut microbiota in the genesis and procession of SALI and its potential therapeutic value, offering a deeper understanding of the pathogenesis and therapeutic avenues for SALI.
