Vitamin D levels in alopecia areata and other alopecias: A retrospective case & #8211;control study at a single institution

Patrick Thanh Tran, Alessandra Chen, Lynn Yi, Carolyn GohInternational Journal of Trichology 2022 14(5):175-177 Recent research has associated alopecia areata (AA), an autoimmune disorder, with deficiency of Vitamin D, which regulates immune processes. This retrospective study compared Vitamin D levels in AA patients to those of other alopecia diagnoses and nonalopecia controls. When compared to controls, patients with AA or other alopecia diagnoses did not demonstrate lower Vitamin D levels. However, when compared to other alopecia diagnoses, AA patients had a statistically significantly higher proportion of patients with Vitamin D deficiency and a lower mean Vitamin D level. Our findings suggest a greater association between lower Vitamin D levels and AA compared to other alopecia diagnoses. Further prospective studies investigating Vitamin D levels and supplementation in AA patients are needed to further elucidate this association and its potential relevance.
