Lower vitamin D status is closely correlated with eczema of the head and neck

摘要

There is growing evidence showing that vitamin D (VitD) deficiency is associated with allergic diseases, such as atopic dermatitis (AD) and asthma, and higher levels of IgE sensitiza-tion. Improvement of AD has also been reported after oral supplementation with VitD.However, the relationship between VitD levels and allergic diseases has not been clarified.In this study we examined the serum VitD status of patients with AD or asthma and healthy control subjects (HCs) by measuring levels of 25-hydroxyvitamin D, which is the most commonly measured indicator of VitD status in the body.
