[Sensitization to aeroallergens in subjects with allergic rhinitis who live in the metropolitan zone of Guadalajara, Jalisco].

BACKGROUND

allergic rhinitis is the most common allergic disease worldwide. Aeroallergens are compromise in its presentation and its prevalence varies in different parts of the world. Aeroallergen sensitization in the Guadalajara metropolitan area is not yet documented.

OBJECTIVE

to determine by means of skin prick test the sensitization prevalence to aeroallergens in patients with allergic rhinitis.

PATIENTS AND

METHODS

We retrospective evaluated the results of skin prick test to different aeroallergens and their prevalence by age group in patients with allergic rhinitis referred to our allergy department.

RESULTS

the complete data of 965 subjects were available, 78% of these had positive skin prick tests, the age range of the patients was 16 to 78 years, 74.9% of which were women; 9% were sensitized to one allergen and 11.5% had more than 15 positive skin prick test. The most frequent interior allergens were house dust mites and outdoor allergens Quercus sp and Fraxinus sp. Males showed the highest reaction frequency to aeroallergens. The age range from 21 to 40 years presented the highest frequency of positive skin prick test.

CONCLUSION

our data demonstrate that house dust mites followed by tree pollens are the most frequent aeroallergens in patient with allergic rhinitis. Positive skin prick test frequency was age associated.
