Asthma, evidences of benefit from vitamin D in The Lancet Respiratory Medicine

The review The Lancet Respiratory Medicine has reported the results from a research conducted by the Queen Mary University of London, demonstrating that oral vitamin D, associated to the standard therapy for asthma, can help halve the risk of asthma exacerbations that require patients to take systemic corticosteroids. The research is the product of an analysis conducted on results from seven randomized and controlled trials, enrolling a total of 955 patients. Those studies have assessed the use of vitamin D supplementation in asthma. The researchers have observed that supplementation reduces exacerbations requiring treatment with systemic corticosteroids by 30% and the risk of an attack requiring emergency department attendance or hospital admission by 50%. The new data join findings from other studies, which reveal that vitamin D can support immune response. (Sources: The Lancet Respiratory Medicine)
