Autism Spectrum Disorder Linked to Distinct Urine Metabolite Pattern

Researchers proposed a new autism spectrum disorder phenotype characterized by elevated urinary microbially derived metabolites.

1

Children with autism spectrum disorder (ASD) exhibited higher urinary concentrations of microbially derived metabolites compared to typically developing controls.
2

The study achieved 90% sensitivity and 100% specificity in classifying children with ASD based on elevated metabolite levels.
3

Researchers identified over 600 metabolites differing between groups, with 23 of 24 selected metabolites significantly elevated in children with ASD.
4

The MDM System developed in the study assigned scores based on elevated metabolites, with children with ASD averaging a score of 3.3.
5

The study was a pilot and highlighted the need for replication in an independent cohort due to its limitations and exclusions.
