Abstract

Background Irritable bowel syndrome (IBS) is a multifactorial disease for which a dysbiosis of the gut microbiota has been described. Bile acids (BA) could play a role as they are endogenous laxatives and are metabolized by gut microbiota. We compared fecal BA profiles and microbiota in healthy subjects (HS) and patients with diarrhea‐predominant IBS (IBS‐D), and we searched for an association with symptoms. Methods Clinical features and stool samples were collected in IBS‐D patients and HS. Fecal BA profiles were generated using HPLC coupled to tandem mass spectrometry. The fecal microbiota composition was assessed by q‐PCR targeting dominant bacterial groups and species implicated in BA transformation. Key Results Fourteen IBS‐D patients and 18 HS were included. The two groups were comparable in terms of age and sex. The percentage of fecal primary BA was significantly higher in IBS‐D patients than in HS, and it was significantly correlated with stool consistency and frequency. Fecal counts of all bacteria, lactobacillus, coccoides, leptum and Faecalibacterium prausnitzii were similar. There was a significant increase of Escherichia coli and a significant decrease of leptum and bifidobacterium in IBS‐D patients. Conclusions & Inferences We report an increase of primary BA in the feces of IBS‐D patients compared to HS, correlated with stool consistency and frequency. A dysbiosis of different bacterial groups was detected, some of them involved in BA transformation. As the gut microbiota is the exclusive pathway to transform primary into secondary BA, this suggests a functional consequence of dysbiosis, leading to lower BA transformation.

  • An increase in primary bile acids in faeces, associated with the decrease in Clostridium leptum, was correlated with the stool consistency in diarrhoea predominant IBS.

    “An increase in primary bile acids in faeces, associated with the decrease in C. leptum (able to transform primary into secondary bile acid), was correlated with the stool consistency in diarrhoea predominant IBS [65] .”

    From Intestinal microbiota in health and disease: Role of bifidobacteria in gut homeostasis (2014) · cites this paper as [65]

  • In the recent small study, the differences in primary bile acid correlated with stool consistency and frequency and were associated with decreased levels of the Clostridium leptum group.

    “Interestingly, these differences correlated with stool consistency and frequency and were associated with decreased levels of the Clostridium leptum group, which contains many of the bacteria that can transform primary into secondary bile acid.”

    From Intestinal microbiota and immune function in the pathogenesis of irritable bowel syndrome (2013) · cites this paper as [54]

  • A recent small study in patients with IBS demonstrated an increase of primary bile acid in the feces of patients with IBS-D compared with healthy subjects.

    “Indeed, a recent small study in patients with IBS demonstrated increase of primary bile acid in the feces of patients with IBS-D compared with healthy subjects (54).”

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.
