A Comparative Study on the Efficacy of Different Stepping-down Therapy for Childhood Asthma

29 juni 2021 uppdaterad av: Xijing Hospital
This study is a 24-week, randomized, parallel group comparative effectiveness study to evaluate the risk of stepping down therapy for patients with well-controlled asthma treated with combination Inhaled corticosteroids (ICS) and Leukotriene receptor antagonist(LTRA).

Betingelser

Detaljerad beskrivning

Asthma guidelines recommend stepping down therapy once asthma is controlled for at least 3 months. Leukotriene receptor antagonist(LTRA). For children with mild persistent asthma, ICS twice a day combined with LTRA can be used for treatment, but there is no consensus on how to reduce drugs in patients with asthma that is well controlled (reducing the dose of ICS or stopping montelukast). We propose a 24-week, randomized, parallel group comparative effectiveness study comparing three approaches in patients with asthma well-controlled for at least three months on combination ICS and LTRA: Halve the dose of ICS firstly and then stop ICS with montelukast only, stop montelukast firstly and then halve the dose of ICS, and halve the dose of ICS firstly and then stop montelukast. Our goal is to compare the rate of treatment failure and determine the optimal treatment strategy. Additional goals include assessing risk factors for step-down failure.

Beskrivning

Inclusion Criteria:

  • age 4-14 years
  • patients had mild to moderate persistent asthma. Patients have treated with low-dose inhaled corticosteroids (equivalent to Fluticasone propionate inhaled aerosol 250 ug/ day) combined with Leukotriene receptor antagonist (Montelulast) at least 6 months of and had no symptoms of asthma for nearly 3 months under well asthma control(Asthma Control Test (ACT) score more than or equal to 20).
  • patients did not suffer from other acute or chronic diseases that may affect their growth and development

Exclusion Criteria:

  • patients with severe persistent asthma or mild persistent asthma failed to be well controlled by low-dose ICS after starting treatment
  • suffer from other diseases: Congenital heart disease, chronic infectious disease, protracted diarrhea, congenital airway disease, congenital vascular ring malformation, congenital immune deficiency, tracheal foreign body, bronchial lymph node tuberculosis and gastroesophageal reflux etc.
  • patients with poor compliance stop medication or fail to take medication on time.

Aktiv komparator: Stop Fluticasone propionate Inhaled Aerosol Firstly
Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day
The study consists of two stages and include three groups. Three groups include: Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day; Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug once a day; Stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug twice daily, and then Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day. The scheme of every group is divided into two stages. Only those whose asthma are well controlled at the end of the first phase will be allowed to proceed to the next phase.
Aktiv komparator: Stop Montelukast Secondly
Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug once a day
