Abstract:
Objective:To evaluate the clinical effect and safety of Qufeng-Zhike prescription in the adjuvant treatment of cough variant asthma (CVA) with severe wind and acute narrow airway syndrome. Methods:A total of 82 patients with CVA with severe Wind and acute narrow airway syndrome, meeting the inclusion criteria in the hospital, were divided into control group and observation group by random number table method between September 2018 and September 2020, with 41 in each group. The control group was treated with budesonide formoterol dry powder inhalation, while the observation group was treated Qufeng-Zhike prescription on basis of control group. Both were treated for 8 weeks. Before and after treatment, scores of TCM symptoms was recorded. The forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF) were detected by spirometer. The peripheral blood eosinophil (EOS) count was detected by full-automatic blood cell analyzer. The level of fractional exhaled nitric oxide (FeNO) was detected by expiration analyzer. The quality of life was evaluated by Leicester cough questionnaire (LCQ). The adverse events were recorded, and clinical curative effect was evaluated. Results:The differences in total response rate of TCM syndromes between observation group and control group was statistically significant [97.6% (40/41) vs. 82.9% (34/41); χ2=4.986, P=0.026]. At 1, 2 and 8 weeks after treatment, scores of TCM syndromes in observation group were significantly lower than those in the control group ( t=2.104, 5.329, 3.527, P<0.05 or P<0.01). After treatment, FEV1 (2.78 ± 0.41 L vs. 2.56 ± 0.37 L, t=2.551), FVC (3.55 ± 0.50 L vs. 3.24 ± 0.44 L, t=2.980) and PEF (357.58 ± 70.98 L/min vs. 316.30 ± 75.60 L/min, t=2.549) in observation group were significantly higher than those in the control group ( P<0.05), while peripheral blood EOS count [(0.26 ± 0.07)×10 9/L vs. (0.30 ± 0.09)×10 9/L, t=2.246], FeNO level (22.55 ± 7.83 μg/L vs. 28.87 ± 9.36 μg/L, t=3.316) and LCQ score (5.62 ± 1.71 vs. 7.04 ± 2.28, t=3.190) were significantly lower than those in the control group ( P<0.05). During treatment, there were no obvious adverse events (liver and kidney function damage) in either group. Conclusion:The adjuvant treatment with Qufeng-Zhike prescription can help to alleviate allergic reactions, improve clinical symptoms, lung function and quality of life in patients of CVA with severe wind and acute narrow airway syndrome.
