Effect of Xiaoer Zhixiaoling Tablets on Airway Reactivity of Cough Variant Asthma in Attack Period
Objective: To evaluated the clinical efficacy of Xiaoer Zhixiaoling tablets on cough variant asthma (CVA) in attack period and its effect on airway reactivity and chronic inflammatory response.Method: One hundred and seventy patients with CVA in attack period were divided into control group and observation group by random number table
with 85 cases in each group. Patients in control group got budesonide aerosol and montelukast sodium chewable tablets. Patients in observation group were also given Xiaoer Zhixiaoling tablets. A course of treatment was four weeks. And a 16-week following-up visit were made. Daytime
nighttime coughing and cough visual analogue scale (VAS) were scored. Before and after treatment
Leicester cough questionnaire (LCQ) and symptoms of traditional Chinese medicine (TCM) were scored. Recurrence during the 16 weeks and cough remission time were recorded. Before and after treatment
airway reaction and levels of interleukin-4 (IL-4)
IL-5
IL-13
eosinophils (EOS) and serum IgE were also detected.Result: The total effect rate in observation group was 93.59%
which was higher than 81.33% in control group (χ2=5.281
P<0.05). After treatment
daytime cough
night cough and total cough scores and cough VAS were all lower than those in control group (P<0.01). Mean cough remission time in observation group was shorter than that in control group (P<0.01). During the 16-week follow-up visit
the recurrence rate in observation group was 39.74%
which was lower than 61.33% in control group (χ2=5.281
P<0.05)
and the average frequency were lower than those in control group (P<0.01). The two dimension scores of LCQ and the total score were higher than those in control group (P<0.01). And levels of IL-4
IL-5
IL-13
IgE and EOS were lower than those in control group (P<0.01). The minimum induced cumulative dose and PD35 were higher than those in control group (P<0.01).Conclusion: Xiaoer Zhixiaoling tablets have a certain effect on in treating cough variant asthma (CVA)
and can relieve symptom
improve the quality of life of the patients
and reduce recurrence frequency. Its mechanism of action may be realized by reducing airway inflammation and airway hyper-responsiveness.
