Changes in the Intestinal Microbiome and Alcoholic and Nonalcoholic Liver Diseases: Causes or Effects?
Open accessAbstract
The prevalence of fatty liver diseases is increasing rapidly worldwide; after treatment of hepatitis C virus infection becomes more widespread, fatty liver diseases are likely to become the most prevalent liver disorders. Although fatty liver diseases are associated with alcohol, obesity, and the metabolic syndrome, their mechanisms of pathogenesis are not clear. The development and progression of fatty liver, alcoholic, and nonalcoholic liver disease (NAFLD) all appear to be influenced by the composition of the microbiota. The intestinal microbiota have been shown to affect precirrhotic and cirrhotic stages of liver diseases, which could lead to new strategies for their diagnosis, treatment, and study. We review differences and similarities in the cirrhotic and precirrhotic stages of NAFLD and alcoholic liver disease. Differences have been observed in these stages of alcohol-associated disease in patients who continue to drink compared with those who stop, with respect to the composition and function of the intestinal microbiota and intestinal integrity. NAFLD and the intestinal microbiota also differ between patients with and without diabetes. We also discuss the potential of microbial therapy for patients with NAFLD and ALD.

FGF15/19 modulates host metabolism and bile acid synthesis in the liver.
“FGF15/19 has been found to modulate host metabolism and bile acid synthesis in the liver (Betrapally et al., 2016).”
From <i>Akkermansia muciniphila</i> alleviates <scp>high‐fat‐diet</scp> ‐related metabolic‐associated fatty liver disease by modulating gut microbiota and bile acids (2023) · cites this paper as Betrapally et al., 2016
In “Role of microbiota in digestion and effect of bile acids” (page unavailable), Fgf15 appears only among genes whose expression correlated with FXR-mediated protection of the mouse intestine. The copy discusses liver metabolism and bile acids elsewhere, but the passages found for FGF15/19 and hepatic bile-acid synthesis do not say that FGF15/19 modulates either process. (LLM, conf=0.76)

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.
