Abstract: Objective To investigate the correlation between atopy and respiratory symptoms, acute exacerbation of patients with chronic obstructive pulmonary disease (COPD). Methods There were 178 patients with stable chronic obstructive pulmonary disease from Beijing Chaoyang Hospital, Capital Medical University from January 2018 to June 2019 were collected. According to the positive serum inhalation allergen screening test, the patients were divided into atopic group (27 cases) and non-atopic group (151 cases). The demographic data, clinical symptoms and laboratory examinations of patients were collected and followed up for 12 months. The acute exacerbation of chronic obstructive pulmonary disease (AECOPD) was recorded. Results After propensity score matching,the symptoms of wheezing in the atopic group(n=27) were higher than those in the non-atopic group(n=77) (77.78% vs 55.84%). The difference was statistically significant (P=0.044). The total serum immunoglobulin(IgE) level in the atopic group was significantly higher than that in the non-atopic group, and the value of forced expiratory volume in first second(FEV1 )was also significantly higher than that in the non-atopic group (P<0.001,P=0.019). Following up for 12 months, the frequency of frequent severe acute exacerbations in the atopic group was significantly higher than that in the non-atopic group (29.63% vs 10.39%), and the difference was statistically significant (P=0.038). Conclusions Atopy can lead to the increase of wheezing symptoms, severe and frequent acute exacerbations in patients with COPD.
