About

To explore the efficacy of fecal microbiota transplantation (FMT) in improving the gastrointestinal symptoms and autism symptoms in patients diagnosed as autism spectrum disorder (ASD) comorbid with gastrointestinal symptoms.

Full description

This trial is designed to reconstruct the intestinal micro-ecology of children with ASD by the interventional treatment of FMT. At the same time, combined with metagenomics and 16S rRNA sequencing techniques, the trial aims to study the efficacy of intestinal micro-ecology for the treatment of autism symptoms and the improvement of gastrointestinal problems and autism symptoms in autistic patients, and to explore potential new techniques for treating children with ASD.

Enrollment: 3 patients

Sex: All

Ages: 3 to 17 years old

Volunteers: No Healthy Volunteers
