Ketogenic diet (KD), a high fat and very low carbohydrates diet, is used worldwide for the treatment of drug resistant epilepsy but, due to its composition, it might exert an impact on gut health. Even though data of KD effects on intestinal microbiota changes are recently emerging, its influence on the gut environment has been scarcely addressed so far. The aim of this study was to investigate whether 1 month of KD affects the gut environment in epileptic patients, by analyzing short chain fatty acids (SCFA) production and fecal water toxicity. A total of seven patients were enrolled. Stool samples were collected before (T0) and after 1 month of KD (4:1 ketogenic ratio) (T1). SCFA were determined by GC-FID and fecal water toxicity in Caco-2 cell culture by comet assay. Concentrations of SCFA significantly decreased after KD (p < 0.05): in particular, we found a 55% reduction of total SCFA level, a 64% reduction of acetate, 33% of propionate, and 20% of butyrate (p < 0.05). Cytotoxicity of fecal water extracted from stool samples was not significantly altered by diet, while genotoxicity was slightly decreased after KD (p < 0.05). Genotoxicity values were consistent with data previously obtained from a healthy Italian population. The present study suggests that 1 month of KD significantly reduce SCFA production. Since SCFA produced by gut microbiota exert many health promoting effects on either the gut environment or human metabolism, these results open a new branch of investigation into KD effects.

Based on earlier observations that colonic contents stimulated ileal motility in the dog, our hypothesis is that the ileum would respond to physiological amounts of short-chain fatty acids (SCFA). Four dogs had isolated ileocolonic loops constructed surgically and boluses of test solutions (15 ml) were instilled into the distal ileum through a small catheter. Intraluminal pressure catheters were used to record motility. Concentrations of SCFA (also called volatile fatty acids) comparable to those found in dog stool (108 mM; 66% acetic, 24% propionic, and 10% butyric acids) regularly stimulated motility with a dose-related effect. The response was not due to the pH of the SCFA solutions and was independent of the pH at which SCFA were instilled. Ricinoleic acid (4 mM) also stimulated motility, as did chenodeoxycholic acid; the bile acid was active only at supraphysiological concentrations (approximately 7.6 mM). Instillates that simulated the composition of ileal chyme in malabsorptive states were without effect. The results suggest that the ileum can "sense" the presence of colonic contents in the lumen and that SCFA are the responsible mechanisms. Stimulation of ileal motility by SCFA could be a response to coloileal reflux.
