The effect of vitamin D is strongest among people with asthma and other lung diseases who are predisposed to respiratory infections. to recommend approval if more safety restrictions were added. Published in the British Journal of Nutrition, a review found in children previously diagnosed with asthma, vitamin D supplementation resulted in a 74% reduction in the risk of asthma exacerbation.
“Vitamin D has significant immunomodulatory effects and, as such, was believed to have an effect on asthma — an immunologically mediated disease,” said Confino-Cohen. “But most of the existing data regarding vitamin D and asthma came from the pediatric population and was inconsistent. Our present study is unique because the study population of young adults is very large and ‘uncontaminated’ by other diseases,” stated Dr Ronit Confino-Cohen.
People with the worst vitamin D deficiency were 36 percent more likely to suffer respiratory infections than those with sufficient levels, according to the research in this week’s Archives of Internal Medicine. Among asthmatics, those who were vitamin D deficient were five times more likely to get sick than their counterparts with healthy levels. And the risk of respiratory infection was twice as high among vitamin D-deficient patients with chronic obstructive pulmonary disease (COPD) than in lung patients with normal levels of the vitamin.
According the World Health Organisation (WHO) about 235 million people suffer from asthma, which is particularly common in children. It cited asthma as one of the major non-communicable diseases facing the world today.
The condition means air passages of the lungs become inflamed and narrowed.
The causes of asthma are not completely understood but it is thought to be a combination of genetic predisposition and environmental exposure to irritants like allergens, tobacco smoke and air pollution.
ARI refers to the infection of the sinuses, throat, airways or lungs usually caused by viruses or bacteria. They can be particularly dangerous for people with asthma. According to a 2013 paper , an estimated 11.9 million episodes of severe ARI and three million episodes of very severe ARI in young children resulted in hospital admissions in 2010 globally.
