Effects of Probiotic Consumption in Children With Autism Spectrum Disorder (ASD)

Summary

The goal of this clinical trial is to determine the effects of Saccharomyces boulardii (Sb) consumption on Ecuadorian children with a diagnosis of autism spectrum disorder (ASD) and digestive symptoms. Saccharomyces boulardii is a probiotic, in other words, a beneficial microorganism. The main question it aims to answer is: Does Sb improve intestinal health, defenses against infections, nutrition and behavior of the participants. Researchers will compare children when they are taking and not taking Saccharomyces boulardii to know if there are changes in digestive symptoms, immune system function, nutritional status and behavior. Participants will take Saccharomyces boulardii for 4 months and will be 4 months without taking Sb. All participants must provide stool, urine and blood samples. A medical, nutritional and psychological team will follow the participants at least 5 times during the study.
