Gut microbiome and sepsis-associated encephalopathy / 国际儿科学杂志

ABSTRACT

Sepsis-associated encephalopathy(SAE)is a common complication with high mortality in patients with sepsis, but its pathogenesis is not clear, and there is no recognized diagnostic criteria and specific treatment.Intestinal tract plays an engine-like role in the occurrence and development of sepsis.The destruction of intestinal barrier and the disorder of intestinal microorganisms can affect the outcome of sepsis, in which gut microbiome affect the pathophysiology of intestine and brain through " the microbiome-gut-brain axis" (MGBA), and "gut microbiome-mitochondrial crosstalk" explains its role at the organelle level.The gut microbiome disorder exists in SAE animal model, while fecal bacteria transplantation can improve the symptoms and prognosis, suggesting that the exploration of gut microbiome may be of certain significance to understand the mechanism of SAE and explore its treatment.Here we review from three aspects the gut microbiome, MGBA and the role of gut microbiome in SAE.
