Evaluation of Association of Allergic Rhinitis with Bronchial Asthma

Allergic rhinitis represents a global health problem. It is a common disease worldwide affecting about 10–50 % of the population and its prevalence is increasing. Although allergic rhinitis is not a fatal disease, it alters the social life of patients, affecting learning performance and work productivity. Moreover, the costs incurred by allergic rhinitis are substantial. In recent years allergic rhinitis has been recognized to be an important risk factor for asthma. The concept of “One Airway, One Disease” was highlighted in the ‘Allergic rhinitis and its Impact on Asthma ‘guidelines and has arisen as a result of the now well-established link between the upper and lower airways. The aim of this study was to evaluate the association between allergic rhinitis and bronchial asthma by determining the incidence of bronchial asthma in patients of allergic rhinitis and the incidence of allergic rhinitis in patients of bronchial asthma. 83 diagnosed cases each of allergic rhinitis and bronchial asthma were recruited from patients attending Otorhinolaryngology and pulmonary department of the institute. All patients were subjected to detail ENT and pulmonary examination and investigated for nasal and bronchial allergy. In the allergic group, which consisted of 83 diagnosed patients of allergic rhinitis, 49 (59.03 %) were diagnosed to have bronchial asthma, whereas in the bronchial asthma group, which consisted of 83 diagnosed patients of bronchial asthma 61 (78.20 %) were diagnosed to have comorbid allergic rhinitis. It was observed that patients with allergic rhinitis were likely to develop bronchial asthma, and patients of allergic rhinitis should be evaluated for bronchial asthma, for early detection and treatment of the co morbid condition.
