POLlinosis and Exhaled Breath Temperature

Summary

The purpose of this study is to determine whether exhaled breath temperature, a surrogate marker of airway inflammation, rises during the pollen season in sensitized subjects with allergic rhinoconjucnctivitis with or without mild asthma. Sublingual Immunotherapy with respective allergens suppresses the seasonal increase of EBT. During the second year (2013) of the trial all patients will be treated with 5 grass allergen extract: carry over differences between the active and placebo arms from the previous year (2012) will be looked for.
