Vitamin A, a naturally occuring antioxidant micronutrient, has immunomodulating effect in patients with immunodeficiency, including an influence on cytokine production and lymphocyte growth and functions. Vitamin A deficiency is associated with a shift from type 2 cytokines to predominantly type I cytokines. The aims of this study were to determine Vitamin A status in Common variable immunodeficiency (CVID) patients and the relationship between Vitamin A status and cytokines production.
