Altered brain-gut axis in autism: comorbidity or causative mechanisms

Mayer, Emeran A., Padua, David, Tillisch, Kirsten·2014·BioEssays

Abstract

The concept that alterated communications between the gut microbiome and the brain may play an important role in human brain disorders has recently received considerable attention. This is the result of provocative preclinical and some clinical evidence supporting early hypotheses about such communication in health and disease. Gastrointestinal symptoms are a common comorbidity in patients with autism spectrum disorders (ASD), even though the underlying mechanisms are largely unknown. In addition, alteration in the composition and metabolic products of the gut microbiome has long been implicated as a possible causative mechanism contributing to ASD pathophysiology, and this hypothesis has been supported by several recently published evidence from rodent models of autism induced by prenatal insults to the mother. Recent evidence in one such model involving maternal infection, that is characterized by alterations in behavior, gut physiology, microbial composition, and related metabolite profile, suggests a possible benefit of probiotic treatment on several of the observed abnormal behaviors.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Initial clinical evidence of MGB interactions primarily stems from associations between dysbiosis and CNS disorders, such as autism, anxiety-depressive behaviors, and functional gastrointestinal disorders.

    “Initial clinical evidence of MGB interactions primarily stems from associations between dysbiosis and CNS disorders, such as autism, anxiety-depressive behaviors, and functional gastrointestinal disorders (63, 65–72).”
  • Alterations in gut permeability have been described in individuals with ASD.

    “Indeed, alterations in gut permeability have been described in individuals with ASD (Julio-Pieper et al., 2014; Mayer et al., 2014).”
  • Dysregulation of interactions between the brain, intestine and enteric microbiome has been implicated in several disease processes involving both the CNS and ENS, including ASD.

    “Dysregulation of the interactions between the brain, the intestine and the enteric microbiome has been implicated in several disease processes involving both the CNS and ENS, including, in addition to ASD [15–17], functional GI disorders such as irritable bowel syndrome [18, 19], psychiatric disorders such as anxiety and depression [20, 21], as well as Parkinson’s disease [22].”

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.
