This study looks at your blood to find allergy-related antibodies if you have pollen allergies to grass or birch. It may help researchers better understand what in the immune system drives allergy symptoms.
This trial studies how well standardized oak (Quercus ilex and Quercus robur) allergen extracts match your specific allergy. It may help refine allergy testing and treatment planning for people with oak-triggered rhinitis, eye symptoms, and/or asthma.
This study looks at how allergic reactions to cat or birch allergens affect people. It aims to find and describe adults and children with these allergies, which may help develop better treatments.
This trial studies an oral immunotherapy approach, where children take tiny, controlled amounts of certain allergy-causing foods to build tolerance. It may help reduce allergic reactions, but only if kids meet safety and monitoring requirements.
This study looks at how older adults (60+) with different histories of birch pollen allergy tolerate nasal exposure to birch pollen. It may help researchers understand why some people lose their allergy symptoms with age.
This study tests how a specific form of treatment is given to people with a tree nut allergy. The goal is to find a safer, more effective way to help your body tolerate tree nuts.
