Compliance with allergen immunotherapy

Immunotherapy has been used for the treatment of allergic rhinitis since the turn of this century. The purpose of this study was to assess the compliance with immunotherapy in a medical center. The charts of 315 patients aged 5 to 18 years, who were prescribed immunotherapy for treatment of allergic rhinitis for at least 1 year before the study, were selected by computer and reviewed. The first analysis consisted of using a log-linear analysis in order to investigate the relationship between source of payment (private or nonprivate), gender, and race. All main effects and interactions were entered into the model (P < .01). The second analysis consisted of using a log-linear analysis to investigate the relationship between the presence/absence of pollen, mold, mite, and animal IgE antibodies, and compliance (model, P < .05). Two hundred fifty-eight patients were private and 57 were nonprivate. Fifty-nine percent (n = 152) of private patients and 46% (n = 26) of nonprivate patients were compliant. Of the 315 patients with allergic rhinitis, 52 also had asthma and 34 had atopic dermatitis. Sixty-one percent of the asthmatic patients and 47% with atopic dermatitis were compliant. Compliance was not increased by the number of allergens to which a patient was allergic. Males were slightly more compliant than females, caucasians were more often private patients and non-whites were more often nonprivate patients. Private patients were more complaint with immunotherapy than nonprivate patients.
