Original description
With an increased prevalence of autism spectrum disorder (ASD) worldwide and in Taiwan, ASD demands urgent attention due to its lasting impact, unclear causes, and limited diagnostic and treatment options. Recent studies highlight disruptions in the gut-brain axis, particularly in ASD. Building on PI Gau's prior research on altered gut microbiota in autism spectrum disorder (ASD), this proposed 4-year study aims to develop evidence-based probiotic intervention (GKB7) and treatment biomarkers for behavioral interventions (Naturalistic Developmental Behavioral Interventions, NDBI, and Program for the Education and Enrichment of Relational Skills, PEERS®) through comprehensive assessments. The ultimate goal is to establish probiotic treatments and diagnostic/treatment biomarkers for ASD utilizing a deep-learning multimodal auxiliary platform.Read full original descriptionShow less

Precision Health in Autism: Exploring the Gut-Brain-Behavior Axis With Biomarkers, Probiotic Efficacy, and Artificial Intelligence Algorithms

With an increased prevalence of autism spectrum disorder (ASD) worldwide and in Taiwan, ASD demands urgent attention due to its lasting impact, unclear causes, and limited diagnostic and treatment options. Recent studies highlight disruptions in the gut-brain axis, particularly in ASD. Building on PI Gau's prior research on altered gut microbiota in autism spectrum disorder (ASD), this proposed 4-year study aims to develop evidence-based probiotic intervention (GKB7) and treatment biomarkers for behavioral interventions (Naturalistic Developmental Behavioral Interventions, NDBI, and Program for the Education and Enrichment of Relational Skills, PEERS®) through comprehensive assessments. The ultimate goal is to establish probiotic treatments and diagnostic/treatment biomarkers for ASD utilizing a deep-learning multimodal auxiliary platform.

Specific Aims:

S.I To conduct a randomized, double-blind, placebo-controlled trial to assess the treatment effects of Clostridium butyricum GKB7 on ASD.

S.II To investigate the effect of NDBI intervention trials using metagenomics as the outcome measure.

S.III To evaluate the effect of PEERS® interventional trials with metagenomics as the outcome measure.

S.IV To develop an artificial intelligence (machine/deep learning) multimodal auxiliary prediction platform that integrates environmental, behavioral/clinical, neurocognitive/imaging, and metagenomic data for ASD diagnosis, subtyping, and impairment prediction.

S.V To identify microbiome and metabolomic biomarkers and endophenotypes of ASD, and to establish Gut-Brain-Behavioral Axes in ASD.

Inclusion: Children and adolescents aged 4 to 15 who are clinically diagnosed with ASD according to DSM-5 criteria and confirmed by the ADI-R/ADOS; Caregivers cooperate with all the assessments and stool and blood collection.

Exclusion: Consumption of antibiotics and yogurt or probiotic products two weeks prior to enrollment; A history of major psychiatric disorders (e.g., schizophrenia, bipolar disorder, major depression), neurological disorders, and substances use disorders; Difficulty following instructions.
