Outcome(s)

Primary Outcome1. SRS-2 1) Changes in the severities of ASD and its core symptoms before and after the FMT are evaluated by SRS-2. 2) Evaluation timings are as follows: at the time before the FMT and at 6, 10, 14, 18, and 30 weeks after the FMT.
Secondary Outcome1. Gazefinder. A change in the ASD severity before and after the FMT is evaluated by the gaze rates for specific areas on the screen of Gazefinder. Evaluation timings are as follows: at the time before the FMT and at 30 weeks after the FMT. 2. PHQ-4. The PHQ-4 is a questionnaire consisting of a 2-item depression scale (PHQ-2) and a 2-item anxiety scale (GAD-2). Changes in the key symptoms and the signs of depression and anxiety before and after the FMT are evaluated by a combined assessment of the PHQ-2 and the GAD-2 scores. Evaluation timings are as follows: at the time before the FMT and at 6, 10, 14, 18, and 30 weeks after the FMT. 3. GSRS. The GSRS is a 15-item questionnaire to evaluate gastrointestinal symptoms which include acid reflux (2 tems), abdominal pain (3 items), indigestion symptoms (4 items), diarrhea (3 items), and constipation (3items). A change in the gastrointestinal symptoms before and after the FMT is evaluated by the combination of the scores of these items. Evaluation timings are as follows: at the time before the FMT and at 6, 10, 14, 18, and 30 weeks after the FMT. 4. BS score. The BS scores are one of the diagnostic items for constipation or diarrhea, which are classified into 7 categories based on the shape, color, and hardness of stools. A change of constipation or diarrhea before and after the FMT is evaluated by this score. Evaluation timings are as follows: at the time before the FMT and at 6, 10, 14, 18, and 30 weeks after the FMT. 5. The number and frequency of adverse events. Adverse events are evaluated at the time when they are observed.
