TLDR
A critical review of current hypotheses regarding the pathogenetic involvement of microbiota in FGID is provided and the results of microbiota-directed interventions are evaluated and clinical guidance on modulation of gut microbiota in IBS is provided.Abstract:
It is increasingly perceived that gut host–microbial interactions are important elements in the pathogenesis of functional gastrointestinal disorders (FGID) The most convincing evidence to date is the finding that functional dyspepsia and irritable bowel syndrome (IBS) may develop in predisposed individuals following a bout of infectious gastroenteritis There has been a great deal of interest in the potential clinical and therapeutic implications of small intestinal bacterial overgrowth in IBS However, this theory has generated much debate because the evidence is largely based on breath tests which have not been validated The introduction of culture-independent molecular techniques provides a major advancement in our understanding of the microbial community in FGID Results from 16S rRNA-based microbiota profiling approaches demonstrate both quantitative and qualitative changes of mucosal and faecal gut microbiota, particularly in IBS Investigators are also starting to measure host–microbial interactions in IBS The current working hypothesis is that abnormal microbiota activate mucosal innate immune responses which increase epithelial permeability, activate nociceptive sensory pathways and dysregulate the enteric nervous system While we await important insights in this field, the microbiota is already a therapeutic target Existing controlled trials of dietary manipulation, prebiotics, probiotics, synbiotics and non-absorbable antibiotics are promising, although most are limited by suboptimal design and small sample size In this article, the authors provide a critical review of current hypotheses regarding the pathogenetic involvement of microbiota in FGID and evaluate the results of microbiota-directed interventions The authors also provide clinical guidance on modulation of gut microbiota in IBSread more

TL;DR: Future studies will focus on understanding the mechanisms underlying the microbiota-gut-brain axis and attempt to elucidate microbial-based intervention and therapeutic strategies for neuropsychiatric disorders.
Journal ArticleDOI
The role of the gut microbiota in nutrition and health
TL;DR: The complex interplay between the gut microbiota, diet and health is considered and better definition of those dominant commensal bacteria, community profiles and system characteristics that produce stable gut communities beneficial to health is important.

The gut-brain axis: interactions between enteric microbiota, central and enteric nervous systems
TL;DR: This review summarizes the available evidence supporting the existence of microbiota-GBA interactions, as well as the possible pathophysiological mechanisms involved, and describes the importance of gut microbiota in influencing these interactions.
Journal ArticleDOI
Functional Gastrointestinal Disorders: History, Pathophysiology, Clinical Features and Rome IV.
TL;DR: This introductory article sets the stage for the remaining 17 articles that follow and offers an historical overview of the FGIDs field, differentiates FGIDs from motility and structural disorders, discusses the changes from Rome III, reviews the Rome committee process, and provides a biopsychosocial pathophysiological conceptualization of FGIDs.

TL;DR: The Illumina-based metagenomic sequencing, assembly and characterization of 3.3 million non-redundant microbial genes, derived from 576.7 gigabases of sequence, from faecal samples of 124 European individuals are described, indicating that the entire cohort harbours between 1,000 and 1,150 prevalent bacterial species and each individual at least 160 such species.

Dietary Modulation of the Human Colonic Microbiota: Introducing the Concept of Prebiotics
TL;DR: By combining the rationale of pro- and prebiotics, the concept of synbiotics is proposed to characterize some colonic foods with interesting nutritional properties that make these compounds candidates for classification as health-enhancing functional food ingredients.

TL;DR: A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.

TL;DR: The faecal microbial communities of adult female monozygotic and dizygotic twin pairs concordant for leanness or obesity, and their mothers are characterized to address how host genotype, environmental exposure and host adiposity influence the gut microbiome.
