University of Pittsburgh
Contrary to earlier results, vitamin D supplements do not prevent severe asthma attacks in at-risk children, according to the first placebo-controlled clinical trial to test this relationship.
These results were published today in JAMA.
"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."
•••••
Even with the rigor of the present study's design, Celedón acknowledges
that he can't draw conclusions about whether very low vitamin D levels
contribute to asthma attacks, but he argues that those children would be
supplemented either way because of known effects on bone health.
