Title: [Efficacy, safety and tolerability of high-dose topiramate with rapid dose titration in symptomatic West syndrome].
Abstract: We investigated the efficacy, safety, and tolerability of high-dose topiramate with rapid dose titration in 12 children with symptomatic West syndrome who suffered from severe motor and intellectual disabilities.Topiramate was introduced as add-on therapy at the daily dose of 1 mg/kg/day, followed by increments of 2 mg/kg at 3- or 4-day intervals, up to a maximum of 19 or 20 mg/kg/day. The ages at the start of topiramate therapy ranged from 5 to 22 months. Prior to the topiramate therapy, the patients had received 2 to 6 antiepileptic agents with (8 patients) or without ACTH (4 patients).Topiramate appeared to be effective in 8 of the 12 patients (67%); four became seizure-free;three showed greater than 90% seizure reduction; one showed greater than 50% seizure reduction. The maintenance dose was 7 to 20 mg/kg/day (mean:17.9 +/- 3.9 mg/kg/day). In 4 of these 8 patients (50%), the spasms relapsed several months after complete cessation or diminution in the frequency of the spasms following treatment with topiramate. All of the 8 topiramate-responsive patients could continue the topiramate therapy throughout this study. The duration of topiramate therapy was 7 to 42 months (median: 12.5 months). There were no severe side effects that necessitated discontinuation of topiramate, including kidney stones.High-dose topiramate with rapid dose titration was revealed to be effective, safe, and well-tolerated in children with symptomatic West syndrome.
