Similar efficacy of ciclesonide versus prednisolone to treat asthma worsening after steroid tapering

SummaryRationaleOral corticosteroids effectively treat asthma exacerbations but are associated with well-described side effects.ObjectiveThis study compared the efficacy and safety of a high dose of an inhaled corticosteroid with oral prednisolone in patients with worsening of their asthma after medication withdrawal.MethodsPatients tapered off their inhaled corticosteroids until they reached predefined criteria of “worsening asthma”. Randomized patients (n=130) were treated double blind with either ciclesonide 800μg twice daily (starting with 800μg hourly for 3h after randomization) or prednisolone 40mg once daily for 2 weeks. Spirometry, daily asthma symptoms, morning and evening peak expiratory flow and blood parameters were assessed in all, methacholine challenge and inflammatory measures were determined in induced sputum in a subset of patients.ResultsCiclesonide was as effective as prednisolone in improving forced expiratory flow in 1s, morning peak expiratory flow and symptoms, the latter improving more rapidly with ciclesonide. No differences were found in methacholine responsiveness or inflammatory measures in sputum or blood. Ciclesonide caused significantly less reduction in morning plasma cortisol levels (p
