Abstract

Vitamin D has been of increased interest in the role of maintaining immune system balance. Alopecia Areata (AA) is a T-cell mediated autoimmune disease which causes anagen-stage hair follicles. Low concentration of vitamin D may be a risk factor for AA. We aimed to determine vitamin D concentrations in patients with AA. 25-hydroxyvitamin D (25(OH)-D) concentrations and 1,25 dihydroxyvitamin D3 (1,25(OH)2D3) were determined from sera collected from patients with AA (n=42) and healthy controls (n=42). 25(OH)-D and 1,25(OH)2D3 concentrations were measured by ELISA method. The concentrations of both 25(OH)-D and 1,25(OH)2D3 were found to be significantly lower in patients with AA than control group (p<0.001 for each analysis). The results show that there is a significant difference between AA patients and normal subjects in terms of serum vitamin D concentrations. Therefore, it is suggested that vitamin D deficiency may have a role in the setting of AA.
