[Immunotherapy is effective in the treatment of allergic rhinitis. Retrospective study of 67 cases].

The value of immunotherapy (IT) in allergic rhinitis is debated. The results of a retrospective study of 67 patients treated with IT from 1985 to the end of 1995 are reported. Patients were classified as cured, improved, or not improved. Variables such as age, number and type of allergens, improvement, release, duration of evolution, and initial and final IgE levels were analyzed. Response to IT was favorable in 81.1% of cases. Improvement and cure were age-dependent, with the cure rate being significantly higher in patients over 30.
