Intervention / Treatment |
---|---|
Experimental: ASD children
20 ASD children who meet the eligibility requirements will receive a fecal microbiota transplantation following a 2-week treatment with Vancomycin (40mg/kg/day) after 3 month waiting period.
Fresh stool sample will be obtained from the donor.
Fecal bacteria transplantation will be achieved via endoscopy, nasogastric/nasointestinal tubes, the proximal colon by colonoscopy, or the distal colon by enema, rectal tube, or sigmoidoscopy or a combined approach.
The amount of fecal bacterial liquid transplantation for children is 5ml/kg each time.
Fecal microbiota transplantation will be conducted at week 3-4, week 6-7, week 9, week 11 and week 13 for total 5 round.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Autism Diagnostic Observation Scale (ADOS) in ASD children
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
The ADOS consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and the person under assessment.
The examiner observes and identifies segments of the subject's behavior and assigns these to predetermined observational categories.
Categorized observations are subsequently combined to produce quantitative scores for analysis and diagnostic classification of ASD.
Children at or above predetermined cutoff lines are considered to be positive for ASD.
The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.

baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
Changes in the Autism Behavior Checklist (ABC) in ASD children
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
ABC is a scale used for nonadaptive behaviors created to screen and indicate the probability of a diagnosis of autism.
The questionnaire including 57 items related to five areas: sensorial, relational, use of body and objects, and social skills.
Scale score> 67 strongly suggests the presence of autism.
The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.
|
baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
Changes in the Childhood Autism Rating Scale (CARS) in ASD children
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
CARS assesses the child on a scale from 1 to 4 in each of 15 dimensions or symptoms.
A total score of at least 30 strongly suggests the presence of autism.
Children with score between 30 and 36 have mild-to-moderate autism while those with score between 37 and 60 have severe autism.
The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.
|
baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
Change in Social Responsiveness Scale (SRS) in ASD children
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
The SRS is a 65-item rating scale with standardized measure of the core symptoms of autism. Each item is scored on a 4-point Likert scale. The score of each individual item is summed to create a total raw score. A total scores results are as follows: 0-62: Within normal limits 63-79: Mild range of impairment 80-108: Moderate range of impairment 109-149: Severe range of impairment. The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation. |
baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation

Change in Autism Treatment Evaluation Checklist (ATEC) in ASD children
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
ASD symptoms will be assessed using the Chinese version of the Autism Treatment Evaluation Checklist (ATEC), which comprise four subscales to measure child speech/language/communication, sociability, sensory/cognitive awareness, and health/physical/behavior.
The scale has 77 items that are scored by parents.
The health/physical/behavior subscale is rated using a 0 (not a problem)-to-3 (serious problem) point scale, whereas the other three subscales are rated using a 0 (not true)-to-2 (very true) point scale.
Higher scores represent more ASD symptoms.
The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.

Change in gastrointestinal symptoms among children with ASD
Time Frame: baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation
|
Assessment will be conducted for the Rome IV diagnoses of cyclic vomiting, functional vomiting, functional dyspepsia, and/or functional constipation.
The presence or absence of meeting criteria for the Rome IV diagnoses will be coded as a binary variable (true/false) to represent resolution of symptoms.
The assessment will be conducted before and after each intervention, namely baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.

Evaluate the difference of the gut microbe composition between children with ASD and healthy children by sequencing faecal metagenome.
Time Frame: 6 months post transplantation
|
Fecal samples from ASD and healthy children were collected at baseline, 2 weeks, 5 weeks , 8 weeks , 10 weeks , 12 weeks and 14 weeks, and 1 month, 3 month, 6 months post transplantation.The composition of the gut microbe was evaluated by sequencing faecal metagenome.
We evaluate the differences in the structure of the flora and its metabolism between the two at the phylum, genus and species levels of the intestinal flora and control children, and to develop a model for predicting the structure of the flora.
