Implication

Prospective case-control study identifies biomarkers linked to SUDEP in adults with drug-resistant focal epilepsy, indicating key attributes for risk assessment.

Key Points

The aim is to identify seizure-related biomarkers for assessing the risk of SUDEP in individuals with drug-resistant focal epilepsy.
Conducted a nested case-control study within a nationwide cohort
Collected clinical data and raw recordings from various monitoring techniques
Matched SUDEP cases with controls based on study center and date of inclusion
Used LASSO-penalized conditional logistic regression to identify risk factors.
A total of 42 deaths during follow-up, including 18 from SUDEP, yielding a rate of 2.64/1000 patient-years.
Identified four significant SUDEP risk factors: extratemporal epileptogenic zone, BMI ≥30, male sex, and predominantly nocturnal seizures.
Certain seizure characteristics like low peri-ictal SpO2 did not show significant association with SUDEP.
