What this trial studies

This study evaluates the effects of a gluten-free and casein-free diet on gastrointestinal symptoms, clinical variables, and the intestinal microbiota in Mexican children diagnosed with autism spectrum disorder. It employs a quasi-experimental pre-post design with time series, where participants will follow the dietary intervention for three months. Clinical evaluations and sample collections will be conducted before and after the intervention to assess changes in health outcomes.

Who should consider this trial

Good fit: Ideal candidates are Mexican children aged 4-10 years diagnosed with autism spectrum disorder.

Not a fit: Patients with celiac disease, gluten-related disorders, or those allergic to dairy products may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved gastrointestinal health and overall clinical outcomes for children with autism spectrum disorder.

How similar studies have performed: While dietary interventions for autism have been explored, this specific approach focusing on a gluten and casein-free diet in this population is relatively novel.
