October 4 2017. Findings from a review and meta-analysis reported on October 3, 2017 in The Lancet Respiratory Medicineadd evidence to an association between vitamin D supplementation and a lower risk of severe asthma attacks requiring steroid treatment or hospital admission.
Researchers at Queen Mary University of London analyzed data from seven randomized, controlled trials that evaluated the effects of vitamin D supplementation in a total of 955 asthmatics treated with standard asthma medication. The team concluded that supplementing with vitamin D was associated with a 26% lower adjusted rate of asthma attacks that required treatment with oral or injectable steroids and a 50% lower risk of experiencing one or more attacks that required emergency department treatment and/or hospitalization. The protective effect of vitamin D supplementation appeared to be stronger among those who initially had low levels of the vitamin, however, the evidence was not definitive. No difference in serious adverse events was observed between participants who received vitamin D and those who received a placebo.
“These results add to the ever-growing body of evidence that vitamin D can support immune function as well as bone health,” stated lead researcher Adrian Martineau. “On average, three people in the UK die from asthma attacks every day. Vitamin D is safe to take and relatively inexpensive so supplementation represents a potentially cost-effective strategy to reduce this problem.”
Professor Hywel Williams, who is the Director of the National Institute for Health Research Health (NIHR) Technology Assessment Programme, commented that “The results of this NIHR-funded study brings together evidence from several other studies from over the world and is an important contribution to reducing uncertainties on whether Vitamin D is helpful for asthma – a common condition that impacts on many thousands of people worldwide.”
