Autism Spectrum Disorder is Related to Increasing Intestinal Prevotella That Can Be Regulated by Vitamin A
Background: Increasing studies suggest that the microbiome-gut-brain axis plays a fundamental role in developing autism spectrum disorder (ASD). Objectives: We aimed to explore biomarkers from gut bacteria in ASD and the dietary vitamin A (VitA) relationship with intestinal bacteria of autistic children and provide a theoretical basis for dietary regulation of ASD. Methods: Ten autistic children aged 2 to 6 from special training facilities were enrolled from 2017 to 2018. At the same time, 10 healthy children aged 2 to 6 from a kindergarten were collected as a control. All participants were from Chongqing, China. The 16sRNA amplicon sequencing was used to analyze children's intestinal bacteria. The serum retinol level was detected by high-performance liquid chromatography (HPLC), and children's dietary intake was analyzed using three-day 24-hour dietary recalls. Results: There were significant differences in alpha diversity between the groups. Also, a higher relative abundance of Prevotellaceae, Prevotella 9, and Roseburia was observed among ASD children. We also found decreases in 9 bacteria (Enterobacteriales, Gammaproteobacteria, Enterobacteriaceae, Clostridiaceae 1, Clostridium sensu stricto 1, Escherichia-Shigella, Bacteroides fragilis, Escherichia coli, and Clostridium neonatale). Dietary VitA intake and serum retinol concentration were lower in the ASD group than in the control group. Meanwhile, serum VitA had a significantly negative correlation with the abundance of intestinal Prevotella 9. Conclusions: Our study helps identify some bacterial biomarkers for ASD, as in previous reports.

Further studies are needed to identify the results by expanding the sample size and developing animal experiments.
