Vitamin D deficiency is associated with poorer lung function in asthmatic children treated with inhaled corticosteroids, according to a new study from researchers in Boston.

“In our study of 1,024 children with mild to moderate persistent asthma, those who were deficient in vitamin D levels showed less improvement in pre-bronchodilator forced expiratory volume in 1 second (FEV1) after one year of treatment with inhaled corticosteroids than children with sufficient levels of vitamin D,” said Ann Chen Wu, MD, MPH, assistant professor in the Department of Population Medicine at Harvard Medical School and Harvard Pilgrim Health Care Institute. “These results indicate that vitamin D supplementation may enhance the anti-inflammatory properties of corticosteroids in patients with asthma.”

The findings were published online ahead of print publication in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
