Abstract

BACKGROUND:

Specific immunotherapy involves administration of allergenic extract in order to reach clinical tolerance of the causal allergens in patients with allergic conditions. When administered, it can provoke side effects.

OBJECTIVE:

To identify systemic reactions after specific immunotherapy administration.

MATERIAL AND METHODS:

A retrospective trial from January 1996 to December 2000. We reviewed patients' files with an allergic disease diagnosis that received immunotherapy. We looked for adverse reactions at 20 minutes and immunotherapy sheets report. The results were analyzed by central and dispersion trends.

RESULTS:

Annual average was of 1,168 applications, 51 (23%) had an adverse reaction. Average age was of 9.5 +/- 2.2 years. 76.5% were male. 125 (5.7%) patients abandoned the treatment and 2,025 (94.3%) continued it. The frequency of intermittent mild asthma/allergic rhinitis was of 51%, persistent moderate asthma/allergic rhinitis, 9.8, and allergic rhinitis, 9.8%. The most common allergen was Dermatophagoides (80.4%). The most frequent reactions were a wheal (64.7%) and exacerbation of clinic baseline (25.5%).

CONCLUSIONS:

Percentage of patients with an immunotherapy immediate reaction was of 2.3% according to literature reports (2.1%).
