Clinical Effects of Vitamin D on the Control of Bronchial Asthma-Is it Relevant?

Abstract

Bronchial asthma is one of the most common chronic respiratory disease worldwide, and is characterised by different phenotypic variations. Acute exacerbations in bronchial asthma are common and leads to repeated hospitalisations leading to increase in direct costs of asthma and thus preventing exacerbations should be an important consideration. Vitamin D has an immunomodulatory action and its deficiency has been associated with asthma epidemics. We hereby critically review the clinical benefits of vitamin D in the control of bronchial asthma and in exacerbations.
