Allergic rhinitis and exercise induced asthma in children Respiratory Asthma
Conditions
Interventions
Three weeks +/- 5 days of treatment with fluticasone furoate (Avamys®) or placebo. Avamys® will be administered through a nasal spray, once daily, 27.5 µg in each nostril. In the first week of the stu

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Analyse the reduction in exercise induced fall of FEV1 after three weeks of treatment with fluticasone furoate 2. Analyse the reduction in exercise induced fall of MIF50 after three weeks of treatment with fluticasone furoate | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To analyse the reduction in exercise induced increase of airway resistance, measured with the forced oscillation technique (FOT), after three weeks of treatment with fluticasone furoate 2. To analyse the reduction in exercise induced decrease of airway reactance, measured with the forced oscillation technique (FOT), after three weeks of treatment with fluticasone furoate 3. Analyze the reduction in fractional exhaled nitric oxide (FeNO), measured with miniNIOX® after three weeks of treatment with fluticasone furoate 4. To analyse the increase in quality of life, measured with the Paediatric Asthma Quality of Life Questionnaire (PAQLQ), after three weeks of treatment with fluticasone furoate 5. To analyse the increase in control of asthma, measured with the Asthma Control Questionnaire (ACQ), after three weeks of treatment with fluticasone furoate | — |
