Detecting and treating low serum vitamin D may be of benefit to children with severe asthma that does not respond to treatment, researchers say.
A UK study shows that children with severe asthma have lower vitamin D levels than those with moderate asthma (*American Journal of Respiratory and Critical Care Medicine* 2011, online 15 Sep).
The reduced vitamin D levels were associated with poorer lung function, poor asthma control, increased medicine use and exacerbations (episodes of worsening symptoms).
Serum vitamin D level was measured in 86 children aged around 11 years, showing for the first time that those with severe, treatment-resistant asthma had lower vitamin D levels (22–38 nmol/L) than those with moderate asthma (29–63 nmol/L) or children with no asthma (45–67 nmol/L).
