Clinical Context
Vitamin D has significant effects on immune function, and an editorial by Devereux and colleagues, which accompanies the current article, reviews the metabolism of vitamin D. Humans obtain approximately 90% of their vitamin D through sunlight, with the remainder coming from diet. Despite this fact, research has demonstrated that more than half of individuals in places with high exposure to sunshine, such as Hawaii, still have evidence of vitamin D deficiency. Foods with significant levels of naturally occurring vitamin D are limited to oily fish and egg yolk, although dairy products are often fortified with vitamin D.
Observational studies regarding the effects of vitamin D on asthma and allergy have yielded mixed results. The current study examines the effects of vitamin D on disease markers in asthmatic children.
Study Highlights
Clinical Implications
Approximately 90% of vitamin D in humans is derived from the sun, but many individuals in sunny areas still have vitamin D deficiency. Vitamin D is found in oily fish and egg yolks, and it has been demonstrated to have immunomodulating effects.
The current study of asthmatic children demonstrates that serum vitamin D levels are inversely related to serum total IgE levels and eosinophilia counts, airway hyperresponsiveness, and hospital admissions for asthma. However, vitamin D levels were unrelated to the mean forced expiratory volume in 1 second.Approximately 90% of vitamin D in humans is derived from the sun, but many individuals in sunny areas still have vitamin D deficiency.
