Abstract

BACKGROUND:

Allergic rhinoconjunctivitis (ARC) has a prevalence of 30% in industrialized countries. For an accurate diagnosis and treatment, it is crucial to identify the causative aeroallergen.

AIM:

To evaluate aeroallergen sensitization in adults with ARC in the city of Temuco, Chile.

PATIENTS AND METHODS:

A skin test against the main aeroallergens present in Temuco was carried out in patients aged 15 to 64 years with ARC diagnosed by medical examination and the Score For Allergic Rhinitis.

RESULTS:

At least one aeroallergen sensitization was present in 234 (62.4%) out of 375 patients. Pollen-sensitized patients were positive mainly for Grasses (44.4%), Plantago (27.8%), Cynodon (26.1%), Sorrel (23.5%), Birch (14.9%), Nothofagus obliqua (13.3%) and Alder (11.1%). Dust mites were the most common non-pollinic sensitizing aeroallergens, including Dermatophagoides pteronyssinus (70.1%) and Dermatophagoides farinae (62.8%).

CONCLUSIONS:

According to our results, skin tests in the city of Temuco should include at least dust mites, pollens of Grasses, Plantago, Cynodon, Sorrel, Birch, Nothofagus obliqua and Alder, because these allergens account for 93% of ARC cases in this city.
