AbstractThe ketogenic diet (KD), characterized by high-fat and low-carbohydrate intake, is currently gaining widespread popularity as a treatment for drug-resistant epilepsy (DRE). In addition to the traditional ketogenic diet, several variants have been introduced to enhance compliance and flexibility, such as the modified Atkins diet (MAD) and the low glycemic index diet (LGID). These adaptations aim to provide patients with more manageable and sustainable options while harnessing the potential therapeutic benefits of DRE. The objective of this study is to evaluate the efficacy and safety of the KD in pediatric patients who exhibit DRE. In this study, we conducted a thorough review of existing literature by searching Cochrane, Embase, Medline, and PubMed. Our approach involved predefined criteria for data extraction and the assessment of study quality. Eleven RCTs with 788 participants were included in this study. The pooled effect estimates revealed a significant association between dietary interventions and seizure frequency reduction of > 50% (OR 6.68, 96% CI 3.52, 12.67) and > 90% (OR 4.37, 95% CI 2.04, 9.37). Dietary interventions also increased the odds of achieving seizure freedom (OR 4.13, 95% CI 1.61, 10.60). The common adverse effects included constipation (39.07%) and vomiting (10%). In conclusion, dietary interventions, notably the KD, hold promise for pediatric DRE, reducing seizures and achieving freedom. These non-pharmacological options improve the quality of life of non-responsive and non-surgical patients. The KD has emerged as a potential therapeutic approach. Further research is needed to address the limitations and investigate their long-term effects.© 2024. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
