Abstract

The presence of advanced fibrosis in nonalcoholic fatty liver disease (NAFLD) is the most important predictor of liver mortality. There are limited data on the diagnostic accuracy of gut microbiota-derived signature for predicting the presence of advanced fibrosis. In this prospective study, we characterized the gut microbiome compositions using whole-genome shotgun sequencing of DNA extracted from stool samples. This study included 86 uniquely well-characterized patients with biopsy-proven NAFLD, of which 72 had mild/moderate (stage 0-2 fibrosis) NAFLD, and 14 had advanced fibrosis (stage 3 or 4 fibrosis). We identified a set of 40 features (p < 0.006), which included 37 bacterial species that were used to construct a Random Forest classifier model to distinguish mild/moderate NAFLD from advanced fibrosis. The model had a robust diagnostic accuracy (AUC 0.936) for detecting advanced fibrosis. This study provides preliminary evidence for a fecal-microbiome-derived metagenomic signature to detect advanced fibrosis in NAFLD.

  • Succinic acid is significantly increased in feces, serum, and liver tissue from MAFLD patients.

    “Alistipes can produce succinic acid (Liu et al., 2016), which is significantly increased in feces, serum, and liver tissue from MAFLD patients (Loomba et al., 2017; Schofield et al., 2017).”

    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 Loomba et al., 2017

    The Results section on microbial metabolism reports a higher abundance of enzymes associated with succinate production in advanced-fibrosis NAFLD, but says the enzyme differences were not statistically significant. It does not report a significant increase in succinic acid itself in feces, serum, or liver tissue; searches for succinic acid and succinate did not locate that finding in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • A metagenomic-based model distinguished advanced fibrosis in adult patients with NASH based on increased Proteobacteria (mostly E. Coli) levels and a decrease in Firmicutes.

    “Similarly, Loomba et al. constructed a metagenomic-based model to distinguish advanced fibrosis in adult patients with NASH based on increased Proteobacteria (mostly E. Coli) levels and a decrease in Firmicutes [232].”
  • These changes are positively correlated with NASH severity and fibrosis in patient cohorts and experimental NASH models.

    “These changes are positively correlated with NASH severity and fibrosis in patient cohorts and experimental NASH models (16, 79–82).”

    From Hepatic Stellate Cell-Immune Interactions in NASH (2022) · cites this paper as [79]

  • MASH fibrosis is linked to a unique gut microbiome.

    “MASH fibrosis is linked to a unique gut microbiome (193-197), and specific microbiome signatures can distinguish human MASH from MASLD (4, 198, 199).”
  • Intestinal microbiota alterations are associated with major conditions like obesity, type-2 diabetes, cardiovascular disease, non-alcoholic fatty acid liver disease, cancer, and the response to antineoplastic therapy.

    “Intestinal microbiota alterations are associated with major conditions like obesity, type-2 diabetes, cardiovascular disease, non-alcoholic fatty acid liver disease, cancer, and the response to antineoplastic therapy [3][4][5][6] .”

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.
