The Effect of Vitamin a Supplementation on Disease Progression, Cytokine Levels and Gene Expression in Multiple Sclerotic Patients: Study Protocol For a Randomized Controlled Trial

Abstract

Multiple Sclerosis (MS) is a chronic inflammatory disease that leads to degeneration of the brain and spinal tissue. Imbalances of CD4+ T cells including Thelper1 (Th1)/Thelper2 (Th2) and Thelper17 (Th17)/Tregulatory (Treg), their secreted cytokines and gene expressions, are important aspects of in immunopathogenesis of MS. Vitamin A and its metabolites can regulate the immune system and appears to be effective in preventing progression of the autoimmune disease such as MS. Disease progression was evaluated By Magnetic Resonance Imaging (MRI), Expanded Disability States Scale (EDSS) and Multiple Sclerosis Functional Composite (MSFC) tests. Cytokine levels were measured using ELISA kits and gene expression was quantified by Real time PCR (RT-PCR) system. According to the difference between the epidemiological and clinical data on the relationship between vitamin A and immune system regulation, this study of the first time assesses Immune function as well as gene expression and progression of the disease following administration of vitamin A supplement.
