Grass Observational Study
Completed
Conditions studied: Grass Allergy, Rhinoconjunctivitis
In brief
Grass pollen allergens are universally recognised as a major cause of allergic diseases in humans, including asthma, allergic rhinitis, conjunctivitis and dermatitis. The purpose of the current study is to evaluate allergy symptoms and allergy medication in subjects with grass-related rhinoconjunctivitis.
