ABSTRACT
Objective To study the effects of different glucocorticasteroid(GCS) inhalation regimens for remissive children with asthma. Methods Three hundred and twenty - three patients with moderate asthma were enrolled on a 12 - week randomized parallel group remissive treatment after a 4 - week baseline treatment. During the baseline treatment terbutaline sulfate 250 ?g tid a day and bud esonide 200 ?g twice a day were given, and oral bronchodilators were used if necessary. The remissive treatment were composed of budesomde inhabit ion 100 ?g once a day (group A), 100 ?g twice a day(group B) and 200 ?g once a day(group 0). Patients subsequently returned to the clinic for 3 additional clinic visits (4,8 and 12 weeks) or telephone visits . On every clinic visit, the daytime and nocturnal time seventy score were recorded and spirometry was conducted in patients who were capable of performing the maneuver. Results Ultimately, 323 children were enrolled on the baseline treatment and 281 (87%) children achieved clinical remission. The rate of compliance decreased gradually during the remissive treatment, but in group B(P
