Prednisone therapy in pediatric epilepsy

Steroids are often an effective treatment for the West's syndrome. There have been few reports of steroid use in children with epilepsy outside the first year of life. I report my experience with prednisone for the treatment of older children with intractable epilepsy. Twenty-eight children (17 boys, 11 girls) aged 18 months to 10 years with intractable epilepsy were studied. Prednisone 1 mg/kg/day for 12 weeks (6 weeks daily and 6 weeks alternate therapy) was prescribed in addition to their regular antiepileptic medications. The parents kept seizure diaries, and the patients were regularly assessed for seizure frequency and side effects. The follow-up period was for 1 to 5 years. Thirteen patients (46%) became seizure free on prednisone and another 18 (40%) had a significant decrease in seizure frequency. Five patients (19%) had no change in seizure frequency. The best outcomes were seen in the absence group in which six out of seven patients became seizure free and in the Lennox-Gastaut syndrome group in which seven out of 10 became seizure free. Side effects were uncommon and included weight gain in five patients and aggression in four patients. Prednisone therapy is a safe and effective adjunctive treatment for epilepsy. It should be considered as an alternative treatment for older children with intractable generalized epilepsy who have failed conventional antiepileptic therapy. (C) 2003 by Elsevier Inc.
