Interictal encephalography can influence patient selection for methylprednisolone therapy in pediatric refractory epilepsy.

We describe our experience with intravenous methylprednisolone pulse therapy in older children with refractory epilepsy. Patients with refractory epilepsy, who were treated with steroids between 2005 and 2010, were retrospectively selected from the database of the pediatric epilepsy clinic at Assaf Harofeh Medical Center. Eight patients (5 boys) aged 1.1 to 9 years (5.2 ± 2.6) were identified. Intravenous methylprednisolone 30 mg/kg/d was given to all patients for 5 days in addition to a stable dosage of the regular antiepileptic drugs. Transient side effects were reported in 4 of the patients during pulse therapy. Significant clinical improvement was noted in 4 patients, accompanied by a significant reduction of the amplitude of the spike-slow wave discharges on the electroencephalogram (EEG). Children with refractory epilepsy, abnormal EEG background, and high-amplitude spike-slow wave discharges appear to be the best candidates for intravenous methylprednisolone pulse therapy.
