Abstract

PURPOSE OF REVIEW: Nonalcoholic fatty liver disease (NAFLD) is a liver disease with high prevalence in western countries. Progression from NAFLD to nonalcoholic steatohepatitis (NASH) occurs in 10-20%. NASH pathogenesis is multifactorial including genetic and environmental factors. The gut microbiota is involved in disease progression and its role is complex. RECENT FINDINGS: NASH is associated with changes in the intestinal microbiota, although findings in recent studies are inconsistent. Dysbiosis can trigger intestinal inflammation and impair the gut barrier. Microbial products can now reach the liver, induce hepatic inflammation and contribute to NAFLD and NASH progression. As the gut microbiota is also involved in the regulation of metabolic pathways, metabolomic approaches identified unique metabolomic profiles in patients with NASH. Altered metabolite patterns can serve as biomarkers, whereas specific metabolites (such as ethanol) have been linked with disease progression. Modifying metabolic profiles might serve as new therapeutic microbiome-based approaches. SUMMARY: In this review, we will highlight findings from the recent literature important to the gut-liver axis. We will predominantly focus on human studies with NASH.

  • Disturbance of the gut-liver axis due to NAFLD-associated dysbiosis is an important extrahepatic source of inflammation in experimental models and human NAFLD cohorts.

    “Disturbance of the gut-liver axis due to NAFLD-associated dysbiosis has also emerged as an important extrahepatic source of inflammation in both experimental models and human NAFLD cohorts (13).”

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.
