Abstract

Background&aims The classical ketogenic diet (KD) is a high-fat, very low-carbohydrate normocaloric diet used for drug-resistant epilepsy and Glucose Transporter 1 Deficiency Syndrome (GLUT1 DS). In animal models, high fat diet induces large alterations in microbiota producing deleterious effects on gut health. We carried out a pilot study on patients treated with KD comparing their microbiota composition before and after three months on the diet.Methods Six patients affected by GLUT1 DS were asked to collect fecal samples before and after three months on the diet. RT - PCR analysis was performed in order to quantify Firmicutes, Bacteroidetes, Bifidobacterium spp., Lactobacillus spp., Clostridium perfringens, Enterobacteriaceae, Clostridium cluster XIV, Desulfovibrio spp. and Faecalibacterium prausnitzii.Results Compared with baseline, there were no statistically significant differences at 3 months in Firmicutes and Bacteroidetes. However fecal microbial profiles revealed a statistically significant increase in Desulfovibrio spp. (p = 0.025), a bacterial group supposed to be involved in the exacerbation of the inflammatory condition of the gut mucosa associated to the consumption of fats of animal origin.Conclusions A future prospective study on the changes in gut microbiota of all children with epilepsy started on a KD is warranted. In patients with dysbiosis demonstrated by fecal samples, it my be reasonable to consider an empiric trial of pre or probiotics to potentially restore the «ecological balance» of intestinal microbiota.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A pilot study in GLUT1 deficiency syndrome showed no statistically significant differences in Firmicutes and Bacteroidetes, but an increase in Desulfovibrio spp.

    “A pilot study showed that there were no statistically significant differences in Firmicutes and Bacteroidetes, but an increase in Desulfovibrio spp., a bacterial group believed to be involved in the exacerbation of the inflammatory condition of the gut mucosa associated with the consumption of fat of animal origin, was observed [366].”
  • In six patients with DRE and glucose transporter type 1 deficiency syndrome who followed the ketogenic diet for three months, reverse transcription polymerase chain reaction analysis of the fecal microbial profiles showed no change in Firmicutes or Bacteroides while showing a significant increase in Desulfovibrio spp.

    “In six patients with DRE and glucose transporter type 1 deficiency syndrome who followed the ketogenic diet for three months, reverse transcription polymerase chain reaction analysis of the fecal microbial profiles showed no change in Firmicutes or Bacteroides while showing a significant increase in Desulfovibrio spp, which is involved in gut mucosal inflammation [127].”

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.
