Brief Summary
Abnormal lung function and high exhaled nitric oxide (FeNO) have been reported in asymptomatic patients with asthma. The investigators aimed to assess whether FeNO and FEF25-75 improve concurrently after treatment with inhaled corticosteroid (ICS) in patients with controlled asthma. Geometric mean (GM) FeNO and spirometric values in patients 8 to 16 years of age who maintained asthma control without controller medication were compared with healthy controls and patients with uncontrolled asthma who were also not receiving controller medications. Patients with controlled asthma and high FeNO (\> 25 ppb) were randomized to ICS treatment or to remain untreated. Changes in spirometric values and GM FeNO from baseline were evaluated after 6 weeks.

Outcome Measures
Primary Outcomes (1)
FeNO
FeNO was measured at week 6 in the treatment and non-treatment groups.
6 weeks after enrollment
Secondary Outcomes (2)
Spirometric values(FEF25-75,FEV1,FEV1/FVC)
6 weeks
Asthma control test scores
6 weeks
Study Arms (2)
Budesonide
EXPERIMENTALPatients with FeNO level greater than 25 ppb were randomly allocated to one of two groups. Randomisation was stratified by baseline FeNO. In one group (treatment group), participants were assigned to once daily treatment with 400 µg budesonide. In the other group (non-treatment group), participants did not receive any medication.
remain untreated

Eligibility Criteria
You may qualify if:
- sensitized to aeroallergens and previously diagnosed to have asthma based on the documentation of airway hyperresponsiveness (methacholine PC20 ≤ 8 mg/mL) and/or reversible airflow obstruction (≥ 12% improvement in FEV1 in response to inhaled beta 2-agonist)
- maintained asthma control without controller medication for 3 months or more
- FeNO \> 25 ppb
You may not qualify if:
- who had significant pulmonary disease other than asthma or a history of gastroesophageal reflux
