Objective:

To identify a preliminary set of urinary metabolite candidates specifically for Parkinson's disease (PD) using a matched-pair cohort design.

Key Findings:
  • A five-metabolite panel was defined: Cyanuric acid, Benzeneacetonitrile, 3-Formylsalicylic Acid, dADP, and ent-cassa-12,15-dien-2beta-ol.
  • The panel demonstrated promising internal discriminative performance with an AUC > 0.95, although the small sample size limits generalizability.
Interpretation:

The study provides a proof-of-concept for isolating PD-specific metabolic signatures, although results are exploratory and not yet validated, necessitating further research.

Limitations:
  • Small sample size limits generalizability and the robustness of findings.
  • The study is exploratory and does not provide a validated diagnostic tool.
Conclusion:

This pilot study establishes a controlled design for future validation of urinary metabolite biomarkers in larger cohorts, emphasizing the importance of further research.
