The efficacy and safety of a ketogenic diet for children with refractory epilepsy in China: a retrospective single-center cohort study.

ABSTRACT: Background:The ketogenic diet (KD) has been implemented in many different counties. However, in China, study concerning the efficacy of the KD is still at an early-stage of evaluation. Furthermore, the KD is thought to be incompatible with Chinese children because of its lack of palatability, especially for the Asian population. In addition, its substantial antiepileptic effect remains to be confirmed. Methods:To evaluate the efficacy and safety of the KD treatment of refractory childhood epilepsy in China, we prospectively enrolled 147 children with refractory epilepsy for KD treatment in Guangdong 999 Brain Hospital and followed up the children for 6 months. Outcome was measured by seizure frequencies before and after the KD diet and adverse effects. We also evaluated influences of different variables (starting age, duration of epilepsy, and others) on the outcome. Results:We found after 1 month, 3 months, and 6 months of KD treatment, 28.0%, 55%, and 67.9% of the subjects remained on diet with a >50% seizure reduction and seizure-free rates of 6.5%, 13.2%, and 23.3%, respectively. Gender, starting age, duration, etiology, classification, and seizure type of epilepsy showed no significant influence on efficacy. Anorexia, diarrhea, and gravel were the main side-effects of the KD treatment. Conclusions:In conclusion, the KD is a safe and efficacious method for childhood refractory epilepsy treatment.
