Objective.
This study aimed to investigate improvements in inflammatory mediator levels in induced sputum and airway hyperresponsiveness (AHR) in cough variant asthma (CVA) during long-term inhaled corticosteroid (ICS) treatment.
Patients and Methods.
Patients with CVA (N=35) and classic asthma (N=26) and healthy subjects (N=24) were recruited into this study.
All patients were treated with budesonide (400 μg/day).
Measurement of inflammatory mediators in induced sputum and PD20-FEV1 (the accumulated provocative dose resulting in a 20% decrease in FEV1) in histamine-challenged subjects was performed every three months after the start of medication.
Interleukin- (IL-) 5 and IL-10 were assayed by ELISA, and the percentage of eosinophils was detected with Giemsa stain.
Trends during the follow-up period were analyzed using a general linear model.
Results.
Inflammatory mediator levels in induced sputum and PD20-FEV1 in patients with CVA and classic asthma differed from those in the control group, although no differences were found in the two asthmatic groups.
PD20-FEV1 significantly increased in CVA patients after ICS treatment for 3 months, while classic asthma patients exhibited a delayed change in AHR.
After ICS treatment, levels of IL-5 and IL-10 as well as the percentage of eosinophils in the CVA group were altered at 3 months and 6 months, respectively.
Accordingly, the level of inflammatory mediators in classic asthma changed more slowly.
Conclusion.
CVA has a greater improvement in airway inflammation and airway hyperresponsiveness (AHR) than classic asthma with respect to inhaled corticosteroid (ICS).
Short-term ICS considerably reduces AHR although longer treatment is required for complete control of airway inflammation.
