Comparative Effectiveness of Levetiracetam vs Phenobarbital for Infantile Epilepsy.


ABSTRACT: Importance:More than half of infants with new-onset epilepsy have electroencephalographic and clinical features that do not conform to known electroclinical syndromes (ie, nonsyndromic epilepsy). Levetiracetam and phenobarbital are the most commonly prescribed medications for epilepsy in infants, but their comparative effectiveness is unknown. Objective:To compare the effectiveness of levetiracetam vs phenobarbital for nonsyndromic infantile epilepsy. Design, Setting, and Participants:The Early Life Epilepsy Study-a prospective, multicenter, observational cohort study conducted from March 1, 2012, to April 30, 2015, in 17 US medical centers-enrolled infants with nonsyndromic epilepsy and a first afebrile seizure between 1 month and 1 year of age. Exposures:Use of levetiracetam or phenobarbital as initial monotherapy within 1 year of the first seizure. Main Outcomes and Measures:The binary outcome was freedom from monotherapy failure at 6 months, defined as no second prescribed antiepileptic medication and freedom from seizures beginning within 3 months of initiation of treatment. Outcomes were adjusted for demographics, epilepsy characteristics, and neurologic history, as well as for observable selection bias using propensity score weighting and for within-center correlation using generalized estimating equations. Results:Of the 155 infants in the study (81 girls and 74 boys; median age, 4.7 months [interquartile range, 3.0-7.1 months]), those treated with levetiracetam (n?=?117) were older at the time of the first seizure than those treated with phenobarbital (n?=?38) (median age, 5.2 months [interquartile range, 3.5-8.2 months] vs 3.0 months [interquartile range, 2.0-4.4 months]; P?
