About the trial

What the trial wants to find out

This study aims to evaluate the efficacy of fecal microbiota transplantation on the gastrointestinal symptoms, autistic symptoms and emotional behavior symptoms of patients with autism spectrum disorder, and investigate the relations between the brain-gut axis, cytokines and autism spectrum disorder. Fecal microbiota transplantation have the potentials to improve intestinal microbiota composition, regulate immunity, and then improve gastrointestinal symptoms, autistic symptoms, emotional behavior symptoms and sleep of children with autism spectrum disorder. Early intervention at school-age may even benefit development, improve cognition and prognosis.

The group in the trial

  • Fecal microbiota transplantationTreatment being tested

    Children with autism spectrum disorder will receive fecal microbiota transplantation after evaluation. After the first intervention, the second transplantation will be arranged 6 months later.
