Abstract

BACKGROUND:

Allergen immunotherapy (AIT) is effective treatment for allergic diseases, and subcutaneous use of depigmented-polymerised extracts may allow rapid up-dosing and safe therapy. To date, there is little information on their safety and clinical effects for children and adolescents with allergic disease.

METHODS:

We performed a retrospective survey of patient notes of 2927 children and adolescents across 136 centres who had received AIT with depigmented-polymerised extracts to pollen or mite allergens for at least one year to collect documentation on safety and clinical symptoms.

RESULTS:

38% of patients had local reactions, of these 145 were larger than 12 cm in diameter. Systemic reactions were documented in 2.7% of children and 1.2% of adolescents. There were no documented cases of anaphylactic shock. There were significant reductions in the frequency of patients with recorded nasal symptoms over time of treatment. Moreover, the prescribing-rate of rescue medication was reduced over the course of SCIT.

CONCLUSION:

These 'real-life'-data from a large retrospective analysis including 2927 children and adolescents with pollen and/or mite induced allergic rhinoconjunctivitis with/or without allergic asthma indicate that AIT with depigmented-polymerised extracts is well tolerated are compatible with clinical response.
