Gut Microbiota, Intestinal Permeability, Obesity‐Induced Inflammation, and Liver Injury

Abstract

Obesity and its metabolic complications are major health problems in the United States and worldwide, and increasing evidence implicates the microbiota in these important health issues. Indeed, it appears that the microbiota function much like a metabolic “organ,” influencing nutrient acquisition, energy homeostasis, and, ultimately, the control of body weight. Moreover, alterations in gut microbiota, increased intestinal permeability, and metabolic endotoxemia likely play a role in the development of a chronic low‐grade inflammatory state in the host that contributes to the development of obesity and associated chronic metabolic diseases such as nonalcoholic fatty liver disease. Supporting these concepts are the observations that increased gut permeability, low‐grade endotoxemia, and fatty liver are observed in animal models of obesity caused by either high‐fat or high‐fructose feeding. Consistent with these observations, germ‐free mice are protected from obesity and many forms of liver injury. Last, many agents that affect gut flora/permeability, such as probiotics/prebiotics, also appear to affect obesity and certain forms of liver injury in animal model systems. Here the authors review the role of the gut microbiota and metabolic endotoxemia‐induced inflammation in the development of obesity and liver injury, with special reference to the intensive care unit setting.

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?

  • Dysbiosis in the gut induces increased permeability of the intestine, leading to increased systemic levels of bacterial products causing low-grade chronic inflammation.

    “dysbiosis in the gut has been shown to induce increased permeability of the intestine, leading to increased systemic levels of bacterial products causing low-grade chronic inflammation.”
  • In the gut, the GM and its metabolites modulate gastrointestinal functions via effects on intestinal permeability, mucosal immune function, intestinal motility and sensitivity, and the ENS.

    “In the gut, the GM and its metabolites have been shown to modulate gastrointestinal functions via their effects on intestinal permeability (32–35), mucosal immune function (36–38), intestinal motility and sensitivity (39, 40), and the enteric nervous system (ENS) (21, 24, 25, 41).”

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.
