Effect of valproic acid on metabolic status and endocrine system in pediatric patients with epilepsy: systematic literature review

Introduction: Valproic acid (VPA) is an acidic compound that is commonly used as an anticonvulsant and mood-stabilizing agent in the treatment of epilepsy, mania and bipolar disorders as well as the prevention of migraine headaches. But, it can affect metabolic and endocrine system resulting in hormonal disturbances and incidence of some metabolic disease, especially in pediatric patients. In this study, we aimed to systematically review the literature wherein metabolic and endocrine effect of valproic acid has been studied in pediatric patients with epilepsy.Methods: To evaluate the relationship between VPA consumption and metabolic diseases, a systematic literature search was performed through searching for related documents in the PubMed and Scopus as two known databases using the following key terms valproic acid , metabolic disease and pediatrics in the title, keywords, and abstract of literatures. Data were then extracted and described.Result: Nearly 934 documents were collected and reviewed based on the main purpose of this study. Of the collected articles, 918 documents were excluded in several step by step processes of article selection, and only 16 relevant documents were included for further data assessment. The results showed that VPA can cause significant increase in plasma concentration of thyroid hormones and therefore increase the risk of metabolic disease in patients with epilepsy.Conclusion:The results of included documents in this review showed that VPA may induce metabolic and hormonal disturbances in pediatric patients, who were on treatment with VPA.
