Brief Summary
Allergic rhinitis might be caused by decreased resistance of nasal barrier to allergens and other environmental insults. About 20 % of the European population suffers from pollen allergies. Birch pollen allergic rhinitis is the most common allergic disease in the Scandinavia and it exists widely also in the Central Europe. Suffering and high costs of pollen allergies may be reduced by understanding the molecular biology of the nasal barriers during allergic response. Our aim is to observe the effect of season and birch pollen immunotherapy on the molecular biology of nasal epithelium and the microbiome.

Outcome Measures
Primary Outcomes (1)
The Total Number of Differentially Expressed Transcripts.
Transcriptomics are evaluated By Next Generation Sequencing. The total number of differentially expressed transcripts are defined from nasal epithelial brushing samples taken at -6 months vs. at +6 months in the two subject groups. The subject groups are the Subcutaneous immunotherapy group and No immunotherapy group.
-6 months vs. +6 months from the starting point of birch pollen subcutaneous immunotherapy.
Secondary Outcomes (1)
Percentage Change in Visual Analogue Scale Scores of Symptoms
-6 months vs. +6 months from the starting point of birch pollen subcutaneous immunotherapy.
Study Arms (2)
subcutaneous immunotherapy
ACTIVE COMPARATORStarts with birch pollen subcutaneous immunotherapy
no immunotherapy
NO INTERVENTIONnot starting with birch pollen subcutaneous immunotherapy
Interventions
