Abstract: To study the epidemiology of allergic rhinitis in bronchial asthma patients from Nanjing, China, and to analyze the correlation of clinical characteristics between allergic rhinitis and bronchial asthma. MethodsA questionnaire survey of 134 bronchial asthma patients from the city of Nanjing was carried out. Their clinical situations and treatment status were investigated in detail, and a database was set up for statistics. ResultsIn 134 bronchial asthma patients, 82 (61.2%) were accompanied with allergic rhinitis. The episode ages and their courses of diseases of both groups had no significant differences (P＞0.10). In respect of severity of bronchial asthma in 82 patients, 56 were in the first degree, 21 in the second degree, 4 in the third degree, and 1 in the fourth degree. In respect to classification of allergic rhinitis, 65 were intermittent and 17 persistent. In respect to severity of allergic rhinitis, 63 were mild and 19 moderatesevere. Of all the asthma patients, 42 (31.3%) had a family history of airway inflammatoryrelated diseases in the direct parent tertstrain.
