Clinical Trial Summary

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.

Description:

Autism spectrum disorder (ASD) is an early neuropsychiatric developmental disorder. About 7-90% of patients with ASD have gastrointestinal problems which can relate to abnormal intestinal microbiota. The brain-gut axis can play a key role in the development of brain, and the interaction between microbiota and central nerve system can relate to the pathophysiology of ASD. Fecal Microbiota Transplantation (FMT) has just been used in the treatment of ASD in recent years. It has the potential to improve gastrointestinal, autistic, emotion and behavior symptoms of patients with ASD. Studies of its efficacy are still scarce, and no study has been conducted in Taiwan. The purpose of this study is to treat patients with ASD by the fecal microbiota transplantation and evaluate its efficacy in gastrointestinal, autistic, emotion and behavior symptoms. It aims to prove the correlations between the brain-gut axis, intestinal microbiota, cytokines and ASD. FMT may improve and change the composition and diversity of intestinal microbiota of patients with ASD and modulate their immune reactions and subsequently improve gastrointestinal, autistic, emotion and behavior symptoms, as well as sleep. Early intervention by FMT in children with ASD may improve their cognition and hence result in better prognosis. Study design: The investigators will recruit 45 patients with ASD and gastrointestinal problems, aged 6-30 years, who are willing to receive FMT and 1-year regular follow-up. The investigators will collect demographic data, blood and stool samples before and after the intervention, and analyze changes of intestinal microbiota and cytokines. The investigators will use subjective questionnaires to evaluate gastrointestinal, autistic, emotion and behavior symptoms, and objective measurements including actigraphy, intelligence and attention tests to evaluate changes in sleep and cognitive functions. The investigators will analyze the correlations between collected variables and compare the ASD group with the healthy control group at baseline to evaluate group differences. The investigators will evaluate the differences of the intervention group before and after FMT, and also compare the intervention group with the waiting list group, to evaluate the efficacy of FMT. Variables will be presented by mean and percentage. The investigators will use independent sample t-test or Chi-squared test for group comparison. The efficacy of FMT will be analyzed by dependent sample t-test or Wilcoxon signed-rank test, and the investigators will use Pearson correlation coefficient to analyze the correlations between variables.

Intervention

Procedure:
• Fecal microbiota transplantation
Fecal microbiota transplantation has been applied to patients with autism spectrum disorder in recent years. Fecal microbiota of healthy donors can be transplanted to patients through colonoscopy. Before donation, donors were comprehensively screened to rule out gastrointestinal symptoms and infections. Patients will receive colon preparation before transplantation. After the intervention, patients will have to stay in bed and be monitored for 24 hours to assure safety.
