Researchers have identified specific RNA biomarkers linked with gastrointestinal issues in children with autism.
The findings could one day lead to individualized treatments aimed at easing their pain.
David Beversdorf, a clinician at the University of Missouri Thompson Center for Autism and Neurodevelopmental Disorders, helps patients with autism spectrum disorder (ASD), many of whom may also be struggling with gastrointestinal or digestive issues, including constipation and diarrhea.
Children with ASD experience these symptoms at a higher rate than their neurotypical peers, and some might not respond favorably to traditional treatments, such as laxatives.
For the new study, researchers collected saliva samples from nearly 900 children, some of whom had autism and experienced gastrointestinal disturbances, at several academic medical centers across the country. After analyzing the samples, the researchers identified specific RNA biomarkers linked to children who had autism and experienced gastrointestinal symptoms.
“We wanted to understand how a child’s body responds to the various bacteria living in the mouth and determine if these interactions contribute to gastrointestinal symptoms,” says Steve Hicks, an associate professor of pediatrics at the Penn State College of Medicine, who collaborated with Beversdorf on the study.
“By identifying these specific microRNAs in the saliva of children with autism, these molecules may serve as future targets for developing novel treatments or tracking medication effectiveness in children with autism-related gastrointestinal conditions.”
RNA have regulatory properties throughout the human body, and the specific RNA identified in the study may have regulatory effects on biological pathways related to metabolism, digestion, depression, and addiction, Beversdorf says.
“It’s one of those ‘chicken or the egg’ cases where we still don’t know if it is the RNA potentially contributing to the gastrointestinal issues, or if the gastrointestinal issues are causing the RNA to be expressed differently, but we have identified a relationship, which will be useful to further explore going forward,” says Beversdorf.
“This research can potentially help contribute to precision medicine one day, where we can follow children with autism and gastrointestinal symptoms over an extended period of time and assess how they might respond to personalized treatments, with the ultimate goal of reducing their symptoms and improving their quality of life.”
The National Institutes of Health funded the study, which is published in Frontiers in Psychiatry. Additional coauthors are from the University of Missouri.
