Exploring interactions between host, microbiota, and environment in children with autoimmune diseases

Study of the Determinants of Pediatric Onset Inflammatory Diseases: Host-microbiota-environment Interactions

University Hospital, Clermont-Ferrand · NCT05176795

This study looks at how the gut bacteria and environment might affect children with autoimmune diseases like juvenile arthritis, type 1 diabetes, or inflammatory bowel diseases, by comparing them to their healthy siblings over time.

What this trial studies

This observational study investigates the interactions between host factors, microbiota, and environmental influences in children diagnosed with juvenile idiopathic arthritis, type 1 diabetes, or inflammatory bowel diseases. It includes an initial case-control phase, where stool samples will be collected from affected children and their healthy siblings at diagnosis, two months post-diagnosis, and one year later. The study aims to understand how early environmental events may influence the microbiotic environment and contribute to the development of these diseases.

Who should consider this trial

Good fit: Ideal candidates include children newly diagnosed with juvenile idiopathic arthritis, type 1 diabetes, or inflammatory bowel diseases.

Not a fit: Patients with recent antibiotic treatment or those with autoimmune or inflammatory diseases other than the specified conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the environmental and microbiotic factors that contribute to autoimmune diseases in children, potentially leading to improved prevention and treatment strategies.

How similar studies have performed: While the approach of studying microbiota and environmental interactions is gaining traction, this specific study's focus on pediatric autoimmune diseases is relatively novel.
