Once daily combined inhaled steroid and ultra long-acting bronchodilator prescribing in pediatric asthma: a dual Center retrospective cohort study

摘要

Objective: A high proportion of children and adolescents who have "difficult" or therapy-resistant asthma, are found to have poor adherence to maintenance therapies. Such individuals are thus difficult asthmatics (for reasons of poor adherence) rather than being young people with true difficult asthma. In our centers, once daily ICS/ULABA (Relvar (TM)) is considered if there is an increase in reported interval symptoms, asthma attacks requiring hospital attendance or rescue oral prednisolone, or persistently low lung function despite reported regular use of a twice daily ICS/LABA preparation. In the majority of these young people, a clinical history of overt non-adherence or a clinical suspicion of covert non-adherence will be noted. Methods: The aim of our retrospective cohort study was to assess the clinical effectiveness of Relvar (TM) in a selected adolescent asthma population. Results: In a pre-selected group of adolescents with likely poor prior adherence to inhaled therapies, a change to Relvar (TM) (once daily combined ICS/ULABA) led to improvements in asthma control, as assessed by ED attendances and oral steroid burden. Conclusions: A prospective study to verify these findings and also explore the effects on quality of life, asthma control, and adherence is warranted.
