What this trial studies

This observational study aims to investigate the correlation between peripheral blood levels of Vitamin A and TREM2 in children diagnosed with Autism Spectrum Disorder (ASD). By recruiting 50 typical children and 50 children with ASD, the study will analyze blood samples to explore potential biomarkers associated with the development and symptoms of ASD. The research will utilize the DSM-5 criteria for accurate diagnosis and will exclude participants with significant comorbid conditions that could confound results.

Who should consider this trial

Good fit: Ideal candidates for this study are children diagnosed with Autism Spectrum Disorder according to DSM-5 criteria, as well as typical children for comparative analysis.

Not a fit: Patients with significant comorbid neurological or physical disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could identify biomarkers that help in understanding the etiology of ASD and potentially lead to improved diagnostic and therapeutic strategies.

How similar studies have performed: While there have been studies exploring biomarkers in ASD, this specific correlation analysis of Vitamin A and TREM2 levels is relatively novel and has not been extensively tested.
