The objective of this prospective study is to assess changes in body mass index(BMI, weight in kilograms/height in meters2) according to age and dosage on epileptic children treated with topiramate. METHODS: From January 2006 to December 2008, prospective studies have been performed on 63 children with epilepsy aged below 15 old who had been treated with topiramate. Patients were classified into 3 groups according to age: 2-5 years as a group 1; 6-10 years as a group 2; 11-15 years as a group 3;, and classified into 2 groups according to dosage: from 2 to 5 mg/kg/day as group A, more than 5 mg/kg/day to 8 mg/kg/day as group B. We have checked BMI of patients four times and evaluated the changes in BMI of each group. RESULTS: BMI at initial presentation and follow-up periods of 6, 12, and 24 months is as follows: 16.3+/-1.25, 14.3+/-1.8, 14.2+/-2.4, and 15.7+/-2.1 in the group 1, 18.5+/-1.23, 15.2+/-1.24, 14.8+/-2.27, and 16.8+/-2.5 in the group 2, 21.6+/-2.31, 16.5+/-2.17, 15.4+/-2.56, and 15.1+/-1.3 in the group 3. Comparing with group A and B is as follows: 19.3+/-2.35 and 18.1+/-1.89 at initial presentation, 15.5+/-2.45 and 15.1+/-1.15 at 6 months, 14.9+/-2.15 and 14.7+/-1.91 at 12 months, 15.9+/-1.28 and 16.0+/-1.12 at 24 months. CONCLUSION: The effect of topiramate on changes of BMI shows difference according to age. In groups of 2-10 years old, BMI was rebounded from lowest value after 12 months, however, in the group of 11-15 years old, BMI kept decreasing at 24 months. And dosage of topiramate does not affect to BMI significantly.
