Reduced level of 25-hydroxyvitamin D in chronic/relapsing Alopecia Areata

Abstract

Current observations link vitamin D deficiency to many autoimmune diseases. There are limited data on vitamin D in Alopecia Areata, an autoimmune disease which in our experience shows seasonality in most of its remitting-relapsing forms. Our results demonstrate the presence of insufficiency of 25-hydroxyvitamin D (25OH-D) in many patients with various clinical forms, correlated with the expected increase of the values of Parathyroid Hormone (PTH). This could suggest the possible clinical use of vitamin D in the management of this frustrating disease.
