Tromsø Birch Rust Allergy Study. Allergy to Birch Rust, a Possible Explanation to Seasonal Airway Allergy During Autumn?

Tromsø Birch Rust Allergy Study. Allergy to Birch Rust Fungi, a Possible Explanation to Seasonal Airway Allergy During Autumn? A Pilot Study With 30 Patients With Suspected Allergy to Birch Rust and 15 Non-allergic Controls.

Source: ClinicalTrials.gov · Last updated 17 Jun 2026

Brief summary (registry, in English)

In this project we study if spores from birch rust fungi (Melampsoridium Betulinum = MB) may be the eliciting allergen in patients with seasonal airway allergy during autumn in North Norway. Patients with suspected allergy to MB are compared with non-allergic controls using data about allergic disease and daily allergic symptoms during autumn. Daily spread of MB spores are compared with daily variations in allergic symptoms. Sensitization to MB and MB allergy are tested with skin prick test, specific immunoglobulin E (IgE) in serum, nasal provocation test and basophil activation test (BAT).
