Abstract

BACKGROUND: Primary sclerosing cholangitis (PSC) is a cholestatic liver disease that is strongly associated with a particular phenotype of inflammatory bowel disease (IBD) with right-sided colonic involvement. In IBD, several studies demonstrated significant aberrancies in the intestinal microbiota in comparison with healthy controls. We aimed to explore the link between IBD and PSC by studying the intestinal mucosa-adherent microbiota in PSC and ulcerative colitis (UC) patients and noninflammatory controls. METHODS: We included 12 PSC patients, 11 UC patients, and nine noninflammatory controls. The microbiota composition was determined in ileocecal biopsies from each patient by 16S rRNA-based analyses using the human intestinal tract chip. RESULTS: Profiling of the mucosa-adherent microbiota of PSC patients, UC patients, and noninflammatory controls revealed that these groups did not cluster separately based on microbiota composition. At the genus-like level, the relative abundance of uncultured Clostridiales II was significantly lower (almost 2-fold) in PSC (0.26 ± 0.10%) compared with UC (0.41 ± 0.29%) and controls (0.49 ± 0.25%) (p = 0.02). Diversity and richness in the microbiota composition differed across the groups and were significantly lower in PSC patients compared with noninflammatory controls (p = 0.04 and p = 0.02, respectively). No significant differences were found in evenness. CONCLUSIONS: Reduced amounts of uncultured Clostridiales II in PSC biopsies in comparison with UC and healthy controls can be considered a signature of a compromised gut, as we have recently observed that this group of as yet uncultured Firmicutes correlates significantly with health.

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.
