This study aimed to evaluate the efficacy of washed microbiota transplantation in the treatment of Tourette's syndrome (TS).
Emerging scientific data support the significant role of microbiota in the modulation of the central nervous system. The reconstitution of gut microbiota might be a potential option to treat Tourette's syndrome (TS). FMT has been reported to be a highly effective therapy to restore the gut microbiota dysbiosis by transferring gut microbiota from healthy donors to patients. The newly improved methodology of FMT based on the automatic washing process and the related delivering consideration was named as washed microbiota transplantation (WMT) by the FMT-standardization study group. FMT has shown treatment potential in several gut-brain axis-related disorders, such as amyotrophic lateral sclerosis and Parkinson's disease, promoting us to investigate its treatment potential for Tourette's syndrome. In this study, investigators aimed to evaluate the efficacy of WMT for Tourette's syndrome and its comorbidities using specialized questionnaires for Tourette's syndrome and investigate the underlying mechanism.

RECRUITINGThe change of Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS)
The YGTSS rating scale is a semistructured clinician- or investigator-administered rating instrument in which participants or caregivers evaluate the number, frequency, intensity, complexity, and interference of motor and phonic tics in the prior week on a 6-point scale from 0 (none) to 5 (severe) \[1\]. The total Motor Tic Severity Score (MTSS; 0-25 points) is added to the total Vocal Tic Severity Score (VTSS; 0-25 points) to determine the TTS (0-50 points).
Time frame: baseline, 4 weeks, 8 weeks, 12 weeks, 6 months post transplantation
the Clinical Global Impressions-Improvement scale
Positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions-Improvement scale. The Clinical Global Impression - Improvement scale is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. and rated as:1.Very much improved; 2.Much improved; 3. Minimally improved; 4. No change; 5. Minimally worse; 6. Much worse; 7.Very much worse.
Time frame: 4 weeks, 8 weeks, 12 weeks, 6 months post transplantation
the change of Gilles de la Tourette Syndrome Quality-of-Life Scale score
The Gilles de la Tourette Syndrome Quality-of-Life Scale with 27 items addresses the issue of how the illness affects patients' well-being. It ranges from 0 to108, and higher values represent a worse outcome.
Time frame: baseline, 4 weeks, 8 weeks, 12 weeks, 6 months post transplantation
the change of The Swanson, Nolan, and Pelham IV Scale (SNAP-IV)
It is an 26-item questionnaire that measured three of the ADHD symptoms, inattention, hyperactivity and oppositional defiant disorder. The 26-item checklist is scored on a 4-point Likert scale ranging between Not At All (0) and Very Much (3).

change of the Sleep Disturbance Scale for Children (SDSC)
The SDSC was 26-item test measuring sleep problems and each item received a value from 0 to 4, with higher scores indicating more severe sleep disorders.
Time frame: baseline, 4 weeks, 8 weeks, 12 weeks, 6 months post transplantation
change of the Gastrointestinal Symptom Rating Scale (GSRS) .
It is based on 15 questions which are scored into 5 domains: abdominal pain, reflux, indigestion, diarrhea, and constipation. Each item weights from 1 to 7, with higher scores reflecting more severe symptoms.
Time frame: baseline, 4 weeks, 8 weeks, 12 weeks, 6 months post transplantation
the difference of the gut microbe composition between individuals with TS and healthy children by sequencing faecal metagenome.
The composition of the gut microbiota is evaluated by sequencing faecal metagenome. We evaluate the differences in the structure of the flora and its metabolism between individuals with TS and control children at the phylum, genus and species levels of the intestinal flora, and to develop a model for predicting the structure of the flora.
Time frame: baseline, 12 weeks, 6 months post transplantation
