Exploring the gut-oral microbiome in autism spectrum disorders

The Role of Gut-oral Axis Microbiome in Autism Spectrum Disorders

Observational IRCCS Burlo Garofolo · NCT05830591

This study looks at the bacteria in the mouths and guts of children with autism to see how it might be different from those without autism and how it could affect their health.

What this trial studies

This observational study investigates the relationship between gut microbiota and Autism Spectrum Disorder (ASD) by analyzing oral and fecal samples from participants. It aims to characterize the microbiome in both ASD patients and healthy controls, focusing on the differences in microbial composition and its potential impact on metabolic and physiological processes. The study will include Caucasian children aged 1 to 17 years, with specific inclusion and exclusion criteria to ensure the integrity of the data collected. By understanding the gut-oral axis in ASD, the research seeks to uncover potential links between microbiota and the disorder's symptoms.

Who should consider this trial

Good fit: Ideal candidates for this study are Caucasian children aged 1 to 17 years diagnosed with Autism Spectrum Disorder.

Not a fit: Patients with other neurological diseases or chronic inflammatory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the role of gut microbiota in ASD, potentially leading to new therapeutic strategies.

How similar studies have performed: While there have been studies exploring the gut microbiome in relation to various conditions, this specific focus on the gut-oral axis in ASD is relatively novel.
