Abstract
BACKGROUND: Many different corticosteroid treatment schedules have been used in order to treat refractory epileptic seizures with encouraging effects on seizure reduction in many epileptic syndromes. OBJECTIVE: The objective is to report our experience with a hybrid treatment regimen for refractory seizures in children with epilepsies other than West and Landau-Kleffner syndrome. We hypothesized that a pulse of corticosteroids effectively reduces seizures while low-dosage maintenance treatment reduces side effects. The results are compared with results from a review of reported corticosteroid and ACTH treatments. METHODS: In this retrospective observational study, 26 children diagnosed with epilepsy with refractory seizures other than West syndrome and Landau-Kleffner syndrome were eligible for a treatment regimen consisting of three days intravenous methylprednisolone (20 mg per kilogram per day) followed by twelve weeks oral prednisolone (0.5 mg per kilogram on alternate days), concluded with a taper phase. Data on effectiveness and side effects were obtained. End-points were the percentages of patients who became seizure free or responded well. RESULTS: Twenty-one patients received the study treatment. Nine (43%) responded well and 6 (29%) became seizure free. All but one patient had a relapse of seizures. Four patients had reversible adverse effects. Data extracted from the literature were consistent with a good response in 48% of 192 children treated with different corticosteroids and in 69% of 103 patients treated with ACTH. CONCLUSION: This new hybrid therapy of a pulse of intravenous methylprednisolone and alternate day oral prednisolone is effective with a favourable side effect profile. Results on efficacy and safety justify a randomized controlled trial.
