脓毒症是宿主对感染的反应失调而导致的危及生命的器官功能障碍,随着脓毒性休克和器官功能衰竭的发展,病死率不断上升.在脓毒症引起的器官功能障碍和死亡中,血管内皮功能紊乱、微循环障碍、凝血功能障碍和免疫抑制、线粒体损伤、细胞焦亡、铁死亡、内质网应激与自噬等机制的异常发挥着重要作用.同时,肠道微生态失衡对脓毒症发展也扮演着不可忽视的角色,最近的研究表明肠道微生物群与脓毒症之间存在紧密的联系.因此,如何通过重建肠道微生态来改善脓毒症患者的预后成为重症医生们关注的焦点.本文就肠道微生态与脓毒症的相关性研究进展进行综述,为临床医生提供更多治疗脓毒症的思路,以改善患者预后.
Research progress on the correlation between intestinal microecology and sepsis
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection,with increasing mortality as septic shock and organ failure progress.Mechanisms such as vascular endothelial dysfunction,microcirculatory disorders,coagulation abnormalities,immune suppression,mitochondrial damage,cell pyroptosis,ferroptosis,endoplasmic reticulum stress,and autophagy play crucial roles in organ dysfunction and death caused by sepsis.Concurrently,the imbalance of the gut microbiota also plays an undeniable role in the development of sepsis,with recent studies demonstrating a close connection between the gut microbiome and sepsis.Thus,how to improve the prognosis of patients with sepsis by reconstructing gut microbiota has become a focus of interest for critical care physicians.This article reviews the research progress on the correlation between gut microbiota and sepsis,providing clinical physicians with more therapeutic strategies to improve patient prognosis.
