Autism Spectrum Disorder
Conditions
Brief summary
This is a study of the effect of a customized probiotic on children and adults with autism, including effects on autism symptoms and gastrointestinal symptoms.
Detailed description
SunGenomics provides its customers with a customized probiotic based on an analysis of the microbiota in their stool samples. Customers who have autism spectrum disorders are invited to participate in this study by completing several questionnaires about their medical history, diet, autism symptoms, and gastrointestinal symptoms before taking the probiotic, and to repeat those questionnaires approximately 3 months later. This is effectively an open-label study.
Interventions
personalized blend of GRAS approved probiotic strains, prebiotics, and botanicals

Children and adults ages 2.5-75 years

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Parent Global Impressions of Autism - Change | change in score between baseline and 3 months | The PGIA-Change assesses the change in 20 different autism-related symptoms on a 7-point scale, from -3 (much worse) to 0 (no change) to +3 (much better) Note that this is a different scale than the PGIA-Baseline, which assesses severity on an absolute scale. The rationale for the two scales is that, based on our clinical experience, it appears that parents can give an approximate value for their child's severity (PGIA-Baseline), but that it is more accurate to ask them about change (with the PGIA-Change) than to ask them about severity again and compare it vs a baseline score (PGIA-Baseline). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Social Responsiveness Scale | change in score between baseline and 3 months | A questionnaire about social skills, where higher scores suggest more severe autism. Scores range from 0 to 195, with higher scores indicating more severe problems. |
| Gastrointestinal Symptom Rating Scale | change in score between baseline and 3 months | A questionnaire which evaluates 15 gastrointestinal symptoms on a severity scale from 1 (none) to 7 (severe). We report the average score of those 15 items |
