A prospective open-labeled trial with levetiracetam in pediatric epilepsy syndromes: continuous spikes and waves during sleep is definitely a target.

| Abstract |
Although LVT is currently extensively prescribed in childhood epilepsy, its effect on the panel of refractory epilepsy syndromes has not been entirely evaluated prospectively. In order to study the efficacy and safety of LVT as adjunctive therapy according to syndromes, we included 102 patients with refractory seizures (6 months to 15 years) in a prospective open-labeled trial. The responder rate was respectively 36% and 32% at 3 and 6 months with 6% and 7% patients becoming seizure free. Among the responders at 6 months (n=33), seizure frequency decreased by 66% and 79% at 3 and 6 months LVT compared to baseline. The highest benefit was for CSWS patients with 2/3 responders, 50% seizure free and no aggravation. LVT provided respectively 39% and 42% responders in focal and absence epilepsies. Infantile spasms and Dravet syndrome experienced the lowest efficacy. No patient with myoclonic-astatic epilepsy or Lennox-Gastaut syndrome was aggravated. LVT dose over 40 mg/kg/d was associated with a lower response rate. Tolerability was excellent. In spite of a small sample, we assume that CSWS is a good candidate for a randomized-controlled trial with LVT.
