Background: Allergen immunotherapy (AIT) leads to the production of antiallergen immunoglobulin (IgG) or "blocking antibody" in the serum and an increase in antiallergen IgG and IgA in nasal secretions. There is also a decrease in the usual rise in antiallergen IgE that occurs after the pollen season.
