  Purpose
The purpose of the present proposal was to investigate the predictive properties of markers in exhaled breath to predict an asthma exacerbation. In addition, the reliability of home monitor assessments to measure asthma control will be examined.

Primary Outcome Measures:
  • number of exacerbations [ Time Frame: 1 year ]
    increase of asthma symptoms, use of short b2-agonists, drop in FEV1% of maximum personal value.

  • asthma control [ Time Frame: 1 year ]
    asthma control questionnaire

  • Quality of life [ Time Frame: 1 year ]
    Asthma Quality of Life questionnaire for children


Secondary Outcome Measures:
  • cost-effectiveness [ Time Frame: 1 year ]
    incremental cost per exacerbation prevented


Enrollment: 102
Study Start Date: November 2010
Study Completion Date: March 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Care as usual
Therapy is guided based on symptoms and lung function. Assessments: home monitoring, symptoms, lung function, FeNO, asthma control, quality of life and diagnostic assessments of non-invasive inflammatory markers in exhaled air and exhaled breath condensate.
