PURPOSE: To report the effectiveness and safety of intravenous levetiracetam in the treatment of children with acute repeated seizures, and status epilepticus in a children's hospital. METHODS: This two-year observational study evaluated all in-patients who received intravenous levetiracetam to treat acute repeated seizures (ARS) or convulsive and non-convulsive status epilepticus (SE). Information was collected on seizure type, epilepsy syndrome and underlying cause, the initial loading dose of intravenous levetiracetam, its effectiveness and safety and whether the patient remained on the drug at final follow-up. Analysis was descriptive. RESULTS: Fifty-one patients aged 0.2-18.8 (mean 7.1) years were evaluated, including 45 with acute ARS or SE and six unable to continue their usual orally administered anti-epileptic medication. The median initial dose of levetiracetam was 14.4 (range 5-30)mg/kg in the 45 patients treated for acute seizures and SE. Twenty three of the 39 (59%) patients with ARS became and remained seizure-free. Levetiracetam terminated status in three of four (75%) patients with convulsive, and the two patients with non-convulsive status epilepticus. Aggressive behaviour occurred in three children, one of whom discontinued treatment. Forty-two patients (81%), including 34 of the 45 patients (76%) treated for ARS or SE remained on levetiracetam at the time of final follow-up, between two and 18 months after receiving the drug. CONCLUSION: This observational study has confirmed previous data that intravenous levetiracetam seems to be effective and safe in the treatment of acute repeated seizures and status epilepticus. A randomised clinical trial is justified to determine whether intravenous levetiracetam should replace intravenous phenytoin as the first long-acting anticonvulsant in the management of acute repetitive seizures and status epilepticus.
