Accumulating studies have raised concerns about gut dysbiosis associating autism spectrum disorder (ASD) and its related
symptoms. However, the effect of gut microbiota modification on the Chinese ASD population and its underlying mechanism
were still elusive. Herein, we enrolled 24 ASD children to perform the first course of fresh washed microbiota transplantation
(WMT), 18 patients decided to participate the second course, 13 of which stayed to participate the third course, and there were
8 patients at the fourth course. Then we evaluated the effects of fresh WMT on these patients and their related symptoms.
Our results found that the sleeping disorder symptom was positively interrelated to ASD, fresh WMT significantly alleviated
ASD and its sleeping disorder and constipation symptoms. In addition, WMT stably and continuously downregulated Bacteroides/
Flavonifractor/Parasutterella while upregulated Prevotella_9 to decrease toxic metabolic production and improve
detoxification by regulating glycolysis/myo-inositol/D-glucuronide/D-glucarate degradation, L-1,2-propanediol degradation,
fatty acid β-oxidation. Thus, our results suggested that fresh WMT moderated gut microbiome to improve the behavioral
and sleeping disorder symptoms of ASD via decrease toxic metabolic production and improve detoxification. Which thus
provides a promising gut ecological strategy for ASD children and its related symptoms treatments.
