Exploring the Effects of Genetic Variants and Inflammation on Vitamins Supplementation Treatment Outcomes in Epilepsy

Exploring the Effects of Genetic Variants and Inflammation on Individualized Treatment Outcomes of Vitamins Supplementation in Patient With Epilepsy

The management of patients with epilepsy is focused on controlling seizures, avoiding treatment side effects, and restoring quality of life. However, about 30% of people are antiepileptic drugs (AEDs) resistance epilepsy after the adequate trials of two AEDs treatment. Genetic factors may contribute to the high interindividual variability in response or adverse effects (such as weight gain and altered lipid profiles) to AEDs. What's more, previous observational studies indicated that vitamin deficiency, such as vitamin B6, is common in patients with epilepsy due to epilepsy itself, AEDs use, or both. Therefore, investigators aim to (1) evaluate the impact of genetic variants on AED and multi-vitamins supplementation in epilepsy, and (2) establish the pharmacogenomics knowledge base of AED and multi-vitamins supplementation on clinical effectiveness in patients with epilepsy.

Detailed Description

In the current study, investigators will evaluate the association among the genetic polymorphisms, epilepsy, and multi-vitamins supplementation from Taiwan Biobank and will further investigate potential genes related to vitamins signal pathways (especially vitamin B6, B9, D, E, and Q) involved in epilepsy. These results will not only generate the field of AEDs pharmacogenomics for further study, but also provide new potential treatment targets that may involve in epilepsy therapeutics. The clinical outcomes indicate disease severity, body weight, metabolic indices (i.e., the fasting levels of lipid), HRQoL, anxiety and depression scores. All outcome indicators will be repeated measured at baseline and after 1, 3 and 6 months multi-vitamins supplementation. All of the participants will be assessed the genotypes.
