Association between pre-diagnostic serum uric acid levels in patients with newly diagnosed epilepsy and conversion...

Area of Science:

• Neurology
• Biochemistry

Background:

• Drug-resistant epilepsy (DRE) presents a significant clinical challenge.
• Identifying biomarkers for DRE risk is crucial for effective patient management.

Purpose of the Study:

• To investigate the association between serum uric acid (UA) levels and the likelihood of conversion to DRE.
• To explore UA as a potential predictive biomarker for DRE.

Main Methods:

• Retrospective cohort study utilizing a common data model database.
• Included 5,672 newly diagnosed epilepsy patients with prediagnostic serum UA levels.
• Categorized patients into hyperuricemia (≥7.0 mg/dL), normouricemia (<7.0 and >2.0 mg/dL), and hypouricemia (≤2.0 mg/dL) groups.

Main Results:

• Overall DRE conversion rate was 19.4% within five years.
• The hypouricemia group exhibited a significantly higher conversion rate to DRE (HR: 1.88 [95% CI: 1.38-2.55]).
• The hyperuricemia group showed a lower conversion rate compared to the normouricemia group (HR: 0.81 [95% CI: 0.69-0.96]).

Conclusions:

• Serum UA levels demonstrate potential as a biomarker for identifying individuals at risk of developing DRE.
• Findings suggest UA levels could inform therapeutic strategies to prevent DRE conversion.
