Abstract:
AIM: Evaluation of the side-effects of conventional
subcutaneous allergen immunotherapy in inhalant allergy.
MATERIAL AND METHODS: Retrospective analysis of early
and late, local and systemic, short-term and long-term
side-effects of 4723 injections given to 224 patients
suffering from intermittent or persistent allergic
rhinitis.
RESULTS: There were 65 systemic reactions in 48
patients (21%) after 61 injections (1.29%). Most of them
were late, and included dyspnoea, rhinorrhoea, fever,
fatigue and urticaria. Incidence of systemic reactions
did not correlate to age or sex, but was higher in grass
pollen than in house dust mite allergy and during the
up-dosing phase of treatment. Late intense local
reactions were observed after 1.6% of injections.
CONCLUSIONS: Allergen immunotherapy in inhalant
allergy is a safe method of treatment.
