Summary

The study is meant to establish a one-step challenge with grass-pollen in patients sensitized for grass-pollen. Therefore the investigators compare a multi-step challenge with grass-pollen with an one-step challenge in order to survey the repeatability and safety.

Conditions

  • Allergic Asthma

Interventions

PROCEDURE

inhalative grass-pollen provocation

Subjects undergo allergen challenges with incremental doses of grass pollen allergen. In subjects, who develop a fall in FEV1 of more than 20%, this will be followed by two single-step challenges.
