OBJECTIVE: Discussion of lung function changes in patients with allergic rhinitis and its clinical significance. METHOD: Using UNICAP100 allergen detector testing 64 patients of allergic rhinitis without asthma symptoms, testing the value of serum total IgE and using immunofluorescence methods for testing inhalation allergen, simultaneously checking the pulmonary function and bronchial provocation. Checking the lung function of 64 patients with non-symptoms of allergic rhinitis in other departments (control group), lung function were compared into two groups of patients. RESULT: In the allergic rhinitis group, 37 patients had abnormal lung function (57.81%), 8 cases in them had obstructive pulmonary ventilation, 12 cases had small airway dysfunction, 31 cases had increased airway resistance respectively. In the control group 15 patients (23.44%) had pulmonary function abnormalities, 2 cases had obstructive pulmonary ventilation, 4 cases had small airway dysfunction, 11 cases had increased airway resistance respectively. Changes in lung function compared in the two groups was statistically significant (P < 0.05). Allergic rhinitis patients with abnormal lung function bronchial provocation test positive rate was significantly higher than the normal lung function in patients with allergic rhinitis, there had statistically significant difference between the two groups (P < 0.05). CONCLUSION After checking the lung function of non-asthmatic symptom patients with allergic rhinitis, we could find abnormal lung function patients of allergic rhinitis and do bronchial provocation test in them, there has important clinical significance of early detection and treatment the patients of allergic rhinitis with bronchial asthma.
