ABSTRACT
Aim:
To assess the safety and effectiveness of an allergen immunotherapy (AIT) with a microcrystalline tyrosine-associated mite allergoid in real-world patients with allergic rhinitis (AR). Materials &methods:
Retrospective, multicenter study assessing the safety of AIT in patients aged 5 to 65 years with AR, with or without asthma, sensitized to mites. Secondary objective was effectiveness, measured as unscheduled visits to healthcare centers and emergency rooms, rhinitis and asthma evolution, medication use and patients' and physicians' disease perception 12 months before and after treatment.Results:
The 306 patients evaluated, with a mean (standard deviation) age of 29.68 (14.66) years, received different treatment compositions and regimens, and 25 (8.2%) experienced nonserious adverse reactions. Unscheduled visits to the specialist and emergency room admissions significantly decreased after immunotherapy (mean [standard deviation] 2.11 [1.95] and 0.3 [0.93] vs 0.66 [1.09] and 0.02 [0.2], before and after treatment, respectively). Rhinitis and asthma classification ('AR and its impact on asthma' and 'Guía Española para el Manejo del Asma', respectively) significantly changed (p < 0.0001 for all classifications), showing symptom reduction after AIT. Median (interquartile range)-combined rhinitis and combined asthma medication scores significantly decreased (4.0 [1.33, 7.0] vs 0.25 [0, 10.0]; p < 0.0001 and 6.94 [1.5, 6.0] vs 0.67 [0, 4.67]; p < 0.0001) within 12 months before and after starting AIT, respectively.Conclusion:
AIT with microcrystalline tyrosine-associated mite allergoid appears to be safe and effective in treating rhinitis caused by mites.Palabras clave
