What this trial studies

This study investigates the effectiveness and safety of probiotics and prebiotics in controlling appetite and weight gain in children diagnosed with Prader-Willi syndrome (PWS). Participants will be divided into three groups, receiving either probiotics, a combination of probiotics and prebiotics, or a placebo. The study aims to observe changes in body weight, gut microbiota structure, and metabolic levels over the course of the intervention. Given the lack of effective treatments for obesity in PWS, this approach leverages emerging evidence linking gut microbiota to obesity management.

Who should consider this trial

Good fit: Ideal candidates are pre-adolescent children diagnosed with Prader-Willi syndrome and meeting obesity criteria.

Not a fit: Patients who have recently used weight loss drugs or antibiotics, or those with gastrointestinal diseases affecting digestion, may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could provide a novel method for managing obesity and appetite in children with Prader-Willi syndrome.

How similar studies have performed: While studies on probiotics and prebiotics for obesity management are emerging, this specific approach in PWS is novel and has not been extensively tested.
