Study hypothesis
Added 25/08/09:
To investigate the role of mediators and cytokines in the pathophysiology of asthma and atopy, potent (specific) antagonists are the preferential tools. In this pilot study, we intend to validate potential outcome parameters and assays for a future study with anti-IL13 compounds. To this end, we intend to validate the reproducibility of skin prick tests (SPT), IgE, and several surrogate markers of allergic inflammation.

Primary outcome measure
Primary study objectives:
1. To test the reproducibility, in atopic subjects with a clinically stable allergic rhinitis of:
1.1. SPT
1.2. Relevant markers of allergic rhinitis and atopy in peripheral blood
2. To validate the following assays for measuring relevant biomarkers in atopic subjects with a clinically stable allergic rhinitis:
2.1. Exhaled nasal air
2.2. Peripheral blood
2.3. Nasal lavage
2.4. Nasal brush
Secondary outcome measures
To identify an appropriate study population for intervention studies with anti-allergic agents such as anti-IL13.
