Lack of control of severe asthma is associated with co-existence of moderate-to-severe rhinitis

Abstract

Eighty-two (15%) patients had no rhinitis, 299 (54%) had mild rhinitis and 176 (31%) moderate/severe rhinitis. In logistic regression models, moderate/severe rhinitis was a predictor for any emergency room visit in the follow-up period [3.83 (2.00–7.35)], for the presence of uncontrolled asthma after 1 year of follow-up [12.68 (1.73–92.85)], for <10% improvement of the airway obstruction [2.94 (1.48–5.85)] and <50% reduction in the number of emergency room visits [2.90 (1.02–8.26)] in the year of follow-up. It was also associated with a smaller chance of more than 90% reduction in the number of emergency room visits in the year of follow-up [0.27 (0.12–0.60)]. In a multivariate linear regression model, severity of rhinitis was positively correlated with a score of asthma severity and inversely correlated to an index of quality of life.
