Sensitization to aeroallergens in a Peruvian pediatric population with allergic diseases

Abstract

In order to determine the profile of sensitization to aeroallergens in pediatric patients with asthma and / or allergic rhinitis, a cross-sectional study was carried out in 411 patients using an allergy skin test. Age, sex, total IgE level and eosinophils were analyzed. The mean age was 8.1 ± 3.7 years and 60.6% were male. The average of the eosinophils and the level of total IgE was 450.1 ± 377.3 cells / mm3 and 861.7 ± 757.6 IU / mL, respectively. Mites were the most frequent sensitizing allergens (79.8%) and Dermatophagoides farinae (65.2%) was the most common. Polysensitization was present in 76.2% of patients. Sensitization was evident in the majority of patients with asthma and / or allergic rhinitis and was associated with age, age groups and total IgE level.
