Abstract

PURPOSE: Benign childhood epilepsy with centrotemporal spikes (BECTS) is known to have a good prognosis, and is easily controlled with antiepileptic drugs. In this study, we evaluate the efficacy of low-dose topiramate (TPM), once at night time in children with BECTS, and compare with that of oxcarbazepine (OXC). METHODS: OXC was used as a first drug in 58 patients with BECTS at the department of pediatrics, Chonnam National University hospital from Jan. 2003 to Nov. 2010. Their medical records were reviewed, focusing on the onset age of seizure, the dosage of drugs, response to treatment and other clinical features. Since Aug. 2008 through Apr. 2011, some newly diagnosed patients with BECTS were given a low-dose (25mg) of TPM, once at nighttime. The efficacy was reviewed in 14 children, who had been followed up in the outpatient clinic for longer than twelve months. RESULTS: Forty five out of 58 (77.6%) patients were well controlled with OXC. Thirteen out of 58 (22.4%), seizures recurred, on whom TPM (n=9) or lamotrigine (n=4) was added. Nine (64.3%) of the 14 patients who were started with low dose TPM became seizure-free for at least 12 months. However, Two out of 14, the dose of TPM had to be increased up to 100 mg/day and 75 mg/day, respectively. In three, seizure was controlled with OXC. CONCLUSION: A single low-dose TPM would be as effective as the conventional OXC without any adverse effects in children with BECTS.
