Vitamin D supplementation may not prevent asthma exacerbations in kids: JAMA
PITTSBURGH- Researchers at UPMC Children's Hospital of Pittsburg have found in first placebo-controlled clinical trial that contrary to earlier results, vitamin D supplements do not prevent severe asthma attacks in at-risk children.The findings from this trial do not support the use of vitamin D supplementation to improve the time to a severe asthma exacerbation in children with asthma and low serum vitamin D levels.
These results were published in JAMA.
Severe asthma exacerbations cause significant morbidity and costs. Whether vitamin D supplementation reduces severe childhood asthma exacerbations is unclear.The researchers conducted a trial to determine whether vitamin D supplementation improves the time to a severe exacerbation in children with asthma and low vitamin D levels.
"The reason that's important is there are colleagues around this country and worldwide who are testing vitamin D levels for kids with asthma and giving them vitamin D," said study lead author Juan C. Celedón, M.D., Dr.P.H., chief of pediatric pulmonary medicine at UPMC Children's Hospital of Pittsburgh. "As a system, it costs a lot of money to run all these tests and give the supplements. We've shown no benefit for children with moderately low vitamin D levels."
