Abstract

Liver cirrhosis occurs as a consequence of many chronic liver diseases that are prevalent worldwide. Here we characterize the gut microbiome in liver cirrhosis by comparing 98 patients and 83 healthy control individuals. We build a reference gene set for the cohort containing 2.69 million genes, 36.1% of which are novel. Quantitative metagenomics reveals 75,245 genes that differ in abundance between the patients and healthy individuals (false discovery rate < 0.0001) and can be grouped into 66 clusters representing cognate bacterial species; 28 are enriched in patients and 38 in control individuals. Most (54%) of the patient-enriched, taxonomically assigned species are of buccal origin, suggesting an invasion of the gut from the mouth in liver cirrhosis. Biomarkers specific to liver cirrhosis at gene and function levels are revealed by a comparison with those for type 2 diabetes and inflammatory bowel disease. On the basis of only 15 biomarkers, a highly accurate patient discrimination index is created and validated on an independent cohort. Thus microbiota-targeted biomarkers may be a powerful tool for diagnosis of different diseases.

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?

  • Patients with cirrhosis have increased Enterobacteriaceae and oral-type taxa such as Veillonellaceae and Streptococcaceae, consistent with microorganisms moving from the mouth to the gut.

    “Studies in the past few years have demonstrated profound alterations of the intestinal microbiota in patients with cirrhosis, showing increased Enterobacteriacea as well as strains that are typically found in the oral microbiota, such as Veillonellaceae and Streptococcaceae, consistent with an invasion of microorganisms from the mouth to the gut in liver cirrhosis32,33.”
  • Metagenomic studies have revealed substantial alterations in gut microbiota composition across a range of chronic liver diseases and in patients with cirrhosis.

    “Metagenomic studies have revealed substantial alterations in the composition of the gut microbiota in a range of CLD as well as in patients with cirrhosis12,32.”
  • Key changes in the intestinal microbiota in cirrhosis include enrichment of Veillonella or Streptococcus and decreased bacteria from the order Clostridiales.

    “Key changes in the composition of the intestinal microbiota in cirrhosis include enrichment of Veillonella or Streptococcus as well as decreased bacteria from the order Clostridiales32.”
  • The majority of patient-enriched species in cirrhosis are of buccal origin, suggesting invasion of the gut from the mouth.

    “Of note, the majority of the patient-enriched species were of buccal origin, suggesting an invasion of the gut from the mouth in liver cirrhosis32.”
  • The gut microbiomes of patients with advanced liver disease and cirrhosis are characterized by increased potentially pathogenic bacteria and reduced beneficial bacteria.

    “The gut microbiomes of patients with advanced liver disease and cirrhosis are characterized by an increase in potentially pathogenic bacteria, along with reduced numbers of bacteria with beneficial properties32,84,85.”

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.
