肠易激综合征(IBS)是世界范围内最常见的功能性肠病,与内脏高敏感性、肠道动力、免疫调节、肠道微生物群改变和脑-肠轴功能障碍有关;然而,其病理生理学仍然知之甚少。肠道菌群及其代谢产物被认为是IBS的可能病因。我们研究的目的是调查特定类型的微生物衍生的代谢产物,特别是胆汁酸,短链脂肪酸,维生素,氨基酸,血清素和次黄嘌呤,这些都与IBS的发病机制有关。以代谢物为重点的研究已经确定了与IBS患者相关的多种微生物靶标,微生物源性代谢物在IBS症状发展中的重要作用已经确立。因此,我们提供了肠道微生物群及其代谢产物对不同亚型IBS(便秘为主的IBS-C,肠道为主的IBS-D)的概述,并提出了关于微生物群在IBS中的作用的有争议的观点。
Irritable bowel syndrome (IBS) is the most common functional bowel disorder worldwide and is associated with visceral hypersensitivity, gut motility, immunomodulation, gut microbiota alterations, and dysfunction of the brain-gut axis; however, its pathophysiology remains poorly understood. Gut microbiota and its metabolites are proposed as possible etiological factors of IBS. The aim of our study was to investigate specific types of microbiota-derived metabolites, especially bile acids, short-chain fatty acids, vitamins, amino acids, serotonin and hypoxanthine, which are all implicated in the pathogenesis of IBS. Metabolites-focused research has identified multiple microbial targets relevant to IBS patients, important roles of microbiota-derived metabolites in the development of IBS symptoms have been established. Thus, we provide an overview of gut microbiota and their metabolites on the different subtypes of IBS (constipation-predominant IBS-C, diarrhea-predominant IBS-D) and present controversial views regarding the role of microbiota in IBS.
