Abstract

We read with interest the recent work by Uhde et al ,1 which demonstrated that physically asymptomatic non-coeliac gluten/wheat sensitivity involves compromised intestinal epithelium barrier dysfunction in conjunction with systemic immune activation events. We also read with interest the recent work by Marchesi et al ,2 which comprehensively reviewed the role of microbiota in physical disorders of the gut and extra-gut organs. But common to these Gut papers was the lack of accounting for anxiety and depression, comorbidities often experienced in gastroenterology clinics. Patients who are otherwise physically asymptomatic often do not explicitly divulge these mental disorders, or the disorders are unintentionally overlooked, yet they report ‘diminished quality of life’. In response to this gap, we explored roles of dysbiosis and gut barrier integrity in individuals physically asymptomatic for gastrointestinal distress, yet nonetheless experiencing mental distress. We hypothesised that anxiety and depressive disorders are linked to human gut dysbiosis with microbiota that secrete lipopolysaccharide (LPS) endotoxin into plasma, which in conjunction with compromised gut barrier integrity has systemic manifestations including the brain. We further hypothesised that this correlates with altered intestinal epithelium paracellular integrity molecules discharged …

  • Barrier breakdown may contribute to MDD-associated elevations in circulating bacteria-derived compounds such as LPS, which is recognized by TLR4 on PBMCs that trigger pro-inflammatory cytokine production.

    “This may contribute to the MDD-associated elevations in circulating bacteria-derived compounds (such as lipopolysaccharide (LPS)108), which is recognized by toll-like receptor 4 (TLR4) on peripheral blood mononuclear cells (PBMCs) that trigger pro-inflammatory cytokine production109.”

    From Central regulation of stress-evoked peripheral immune responses (2023) · cites this paper as [108]

    The paper reports significantly elevated plasma LPS and gut-barrier biomarkers in a combined depressive-disorder/anxiety-disorder group versus controls, and proposes a link between compromised barrier integrity and LPS entering plasma (main text, Figure 2 discussion and study description; page unavailable). It does not establish elevated LPS specifically in MDD. The TLR4/PBMC mechanism is attached to a different citation in the citing sentence, so it is not judged here. (LLM, conf=0.86)

  • Plasma biomarkers of increased gut permeability, including LPS and zonulin, have been found in greater abundance in people with depressive disorders compared to healthy controls.

    “plasma biomarkers of increased gut permeability, including LPS and zonulin, have been found in greater abundance in people with depressive disorders compared to healthy controls238.”

    From Comorbidity between major depressive disorder and physical diseases: a comprehensive review of epidemiology, mechanisms and management (2023) · cites this paper as [238]

    The results passage (page not provided) reports significantly elevated plasma LPS and zonulin in the DEP/ANX group versus controls. The methods passage defines that group as people with either a depressive or an anxiety disorder; the paper does not report this comparison for people with depressive disorders alone. (LLM, conf=0.88)

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.
