Role of vitamin D3 supplementation in allergic rhinitis: an outpatient department based prospective analytical observational study
Abstract
Allergic rhinitis (AR) is the most common type of chronic rhinitis, affecting 10-20% of the population, and evidence suggests that the prevalence of the disorder is increasing. Severe AR has been associated with significant impairments in quality of life, sleep and work performance. 1 There are good treatments available for AR, including antihistamines and topical corticosteroids. 2 Yet, there is a need for new treatment options, particularly aiming at new targets and associated with reduced side effects. The prevalence varies among countries, probably because of geographic and aeroallergen differences. 3-6 In India, AR is considered to be a trivial disease, despite the fact that symptoms of rhinitis were present in 75% of children and 80% of asthmatic adults. 7
