ABSTRACT
OBJECTIVE:
To describe the impact of nebulized budesonide inhalation suspension (BIS) on guardian-reported symptoms in Chinese pediatric patients with cough variant asthma (CVA).METHODS:
This was a secondary analysis of a prospective, non-interventional study conducted at 39 Chinese sites. Patients with CVA aged ≤5 years were classified according to the severity of baseline symptoms mild (symptom score ≤3) or severe (symptom score >3). Daytime and night-time symptom scores, disease control, use of bronchodilators, and improvements in symptoms control were compared after 1, 3, 5 and 7 weeks of treatment between groups.RESULTS:
Among 914 patients, 821 (89.8%) completed the 7-week treatment. Among all patients, 368 (40.3%) were classified as mild CVA and 529 (57.9%), as severe CVA. Symptom scores in the severe group were higher than those in the mild group at weeks 1, 3, and 5 (p < 0.05), but not at week 7 (p > 0.05). Further, more patients in the mild group achieved disease control at any time point (98.6% at 3 weeks and 99.7% at 7 weeks), compared with the patients in the severe group (p < 0.001). The proportion of patients requiring bronchodilators differed between the groups until week 5 (p < 0.001). No severe or drug-related adverse events were reported.CONCLUSIONS:
Individualized BIS treatment should be formulated according to the severity of baseline symptoms in CVA patients. Patients with mild CVA showed improvement after a shorter treatment time, while patients with severe CVA might require a longer time to respond to the treatment.Key words
