Genetic aetiologies in relation to response to the ketogenic diet in 226 children with epilepsy.

ABSTRACT: A ketogenic diet is used in children with drug-resistant epilepsy but predictors for efficacy are largely lacking. Our aim was to evaluate if causative genetic variants could predict seizure response to the ketogenic diet. A cohort study of 226 children with refractory epilepsy and classic ketogenic diet treatment for at least 3 months (76.9% of the 294 who started) was performed. The median age at diet start was 5.1 years (range 0.1-17.8), 118 were girls and 108 boys. They had previous trials of a median of 6.0 anti-seizure medications (range 0-12) and intellectual disability was found in 87%. Seizure response (≥50% reduction) was found in 138/226 patients (61.1%) at 3 months, 121 (53.5%) at 6 months, 107 (47.3%) at 1 year and in 80 (37.0%) at 2 years follow-up of ketogenic diet. Age of e
