Abstract

BACKGROUND: Emerging evidences have indicated that the composition of gut microbiota was significantly influenced by central nervous system diseases. The digestion and metabolism disturbances of patients with amyotrophic lateral sclerosis (ALS) might be strongly associated with ALS; however, this has rarely been evaluated in these populations. This study was to evaluate bacterial and archaeal composition of gut flora and the corresponding metabolism performance of these micro-organisms in fecal samples of patients with ALS. METHODS: A comparative study was performed on the intestinal microbiota from eight patients with ALS and eight healthy individuals at Huadong Hospital during November 2017 to April 2018; meanwhile, the metabolite concentrations of human endotoxin, short-chain fatty acids (SCFA), NO2-N/NO3-N, and γ-aminobutyric acid were also evaluated by spectrophotometry methods. The correlations between intestinal microbiota and metabolite concentration were compared between the two groups using one-way analysis of variance; the relative abundance of beneficial and harmful micro-organisms in fecal samples was also analyzed. RESULTS: In general, the richness and evenness of bacterial and archaeal communities of healthy individuals were healthier than that of patients with ALS. The phylum Firmicutes/Bacteroidetes ratio, genus Methanobrevibacter showed an enhancive tendency in patients with ALS, whereas the relative abundance of beneficial micro-organisms (genera Faecalibacterium and Bacteroides) presented a significant decrease tendency in patients with ALS. In addition, the average concentrations of human endotoxin, SCFA, NO2-N/NO3-N, and γ-aminobutyric acid in patients with ALS and healthy individuals were 64.2 vs. 65.3 EU/mL, 57.5 vs. 55.3 μg/mL, 5.7 vs. 5.3 ng/mL, and 6.1 vs. 5.4 μmol/L, respectively, indicating that the digestion and metabolism functions of gastrointestinal tract of patients might decline with this disease. CONCLUSIONS: The relative abundance of beneficial and harmful micro-organisms respectively showed decrease and increase tendency in patients with ALS.

  • Gut microbiome composition and metabolome are altered in many brain disorders.

    “Interestingly, several studies have found that the gut microbiome composition and, consequently, metabolome are altered in many brain disorders (138–142).”

    From The Role of Short-Chain Fatty Acids From Gut Microbiota in Gut-Brain Communication (2020) · cites this paper as [142]

    The Discussion reports altered gut microbial composition in patients with ALS. The Results report only nonsignificant increases in the measured fecal metabolites, so they do not establish a changed metabolome as a consequence of the microbial changes. This study focuses on ALS; it does not establish the claim across many brain disorders. (LLM, conf=0.88)

  • A comparative study in human ALS patients showed an elevated relative abundance of pathobionts compared to bacterial strains related to beneficial metabolism function.

    “A comparative study conducted in human patients showed an elevated relative abundance of pathobionts compared to bacterial strains related to beneficial metabolism function (142).”

    From The Role of Short-Chain Fatty Acids From Gut Microbiota in Gut-Brain Communication (2020) · cites this paper as [142]

    The Discussion reports that beneficial Faecalibacterium and Bacteroides decreased in patients with ALS compared with healthy individuals. The Introduction describes an increase in harmful Dorea, but attributes that finding to an earlier study; this paper’s own reported findings do not establish an increase in bacterial pathobionts.

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.
