Abstract

Background: Alterations of intestinal microbiota and hypersensitivity to colonic distension are two features of the irritable bowel syndrome (IBS). However, the role of intestinal microbiota in visceral hypersensitivity of IBS patients is far to be established. The aim of our study was to determine whether the intestinal microbiota is involved in the visceral hypersensitivity in IBS. Methods: The painful response to colorectal distension and colonic mucosal parameters were assessed in gnotobiotic rats. Germfree (GF) rats were inoculated with the fecal microbiota from IBS patients characterized by hypersensitivity to colorectal distension (IBS HMA rats) or from non‐hypersensitive healthy volunteers (Healthy HMA rats). Conventional rats were studied as normosensitivity control. Fecal microbial analyses were carried out in human and HMA rats fecal samples using cultural and molecular approaches. Key Results: The microbial dysbiosis of the IBS gut microbiota (more sulfate‐reducing bacteria and Enterobacteriaceae and less bifidobacteria) could be maintained in gnotobiotic rats. The number of abdominal contractions in response to colorectal distensions was significantly higher in IBS HMA rats than in healthy HMA rats. No difference was observed between healthy HMA and conventional rats. Colorectal compliance, epithelial paracellular permeability, and density of colonic mucosal mast cells were similar in the three groups of rats. Conclusions & Inferences: We herein showed that sensitivity to colonic distension of IBS patients can be transferred to rats by the fecal microbiota. Mucosal alterations associated with microbiota transfer are not involved in this hypersensitivity. The altered IBS microbiota may have important role in the hypersensitivity characterizing IBS patients through specific bacterial metabolites.

  • Evidence for a role of the gut microbiome in regulating GI sensation comes from gnotobiotic studies showing transfer of the visceral hypersensitivity phenotype after transplantation of gut microbiota from IBS patients into germ-free mice.

    “Evidence for a role of the gut microbiome in regulating GI sensation (Figure 3) comes from gnotobiotic studies showing transfer of the visceral hypersensitivity phenotype following transplantation of gut microbiota from patients with IBS into germ-free (GF) mice 66.”
  • Reports describe microbiota-induced hypersensitivity to colonic distension in germ-free rats inoculated with fecal microbiota from IBS patients.

    “Study of specific IBS pathways include reports describing microbiota-induced hypersensitivity to colonic distension in GF rats inoculated with the fecal microbiota from IBS patients66.”
  • Microbiota composition changes in IBS are inconsistent across studies, possibly due to heterogeneous populations and differing sample preparation and analysis methods.

    “However, changes in microbiota composition are not consistent across studies, possibly due to heterogeneous study populations and differing methodologies for sample preparation and analysis.”
  • Several currently used IBS therapies, including prebiotics, probiotics, dietary restrictions, and antibiotics, modulate gut microbiota.

    “several currently used therapies, such as pre and probiotics, dietary restrictions and antibiotics, modulate the gut microbiota.89”
  • Gut microbiota is an important target for study in treating functional disorders such as IBS.

    “Thus, gut microbiota is an important target for study in the treatment of functional disorders such as IBS”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
