Is Intralymphatic Allergen Immunotherapy Effective and Safe?

Summary

15 patients with moderate to severe allergic rhinitis against grass were recruited and enrolled in the study. They received three open label intralympatic grass allergen injections with the dose 1000 SQ-U each and with one month interval. The next year the patients were randomized double blind to an active or placebo booster injection of 1000 SQ-U before the pollen season. Grass specific IgG4 levels were measured before and at various time ponts after treatment.
