Abstract:
OBJECTIVE To invest igate the correlation between fractional exhaled nitric oxide(FeNO) and lung function in artemisia argyi allergy patients. Whether the course of disease and rhinitis score are correlated with FeNO and lung function. METHODS A total of 88 patients with mugwort pollen allergy, who visited the hospital between August and September 2017 and August and September 2018, the results of their FeNO and Pulmonary ventilation function, were included in this study. RESULTS Compared with patients with a duration of 9 years or more, FeNO and FEV1％ of patients with a duration of 5 years were significantly different(P =0.004, P =0.032), and FeNO increased with the extension of the duration, while FEV1％ decreased gradually. FeNO was negatively correlated with FEF25％-75％pred and FEV1％, while there was no correlation with FEV1％pred. Rhinitis score was positively correlated with FeNO. There was no correlation with FEV1％pred, FEV1％, FEF25％-75％pred. CONCLUSION With the development of mugwort pollen allergy, the probability of airflow limitation is also increased. To some extent, FeNO can predict the changes of airway function early, and can be used as a monitoring indicator for asthma prediction.FeNO value can reflect the degree of inflammation of the body, and can be used in the auxiliary diagnosis of the severity of allergic rhinitis patients.
