Abstract

Objective:  Determining the incidence of allergy to certain common respiratory allergens in children with bronchial asthma aged 2 to 16 years at the Vietnam National Children's Hospital. Method: Cross-sectional descriptive study in 100 asthmatic children aged 2-16 years who visited and monitored for inpatient and outpatient treatment at the Department of Immunology – Allergy – Joints of the Vietnam National Children's Hospital from July 2021 to July 2022. Prick test is performed with 7 types of respiratory allergens such as: Dermatophagoides Pteronyssinus (Dp), Dermatophagoides Farine (Df), Blomiatropicalis (Bt), dog hair, cat hair, cockroaches and Aspergillus mix fungus. Results: The proportion of children's asthmatics allergic to respiratory allergens was 87.0%, the majority of children who are allergic asthma to multiple allergens and allergies to 4 types of allergens accounted for the highest rate of 31.0%. Besides, house mites accounted for the highest proportion Dp 83.0%, Df 83.0%, Bt 44.0%, cockroaches 33.0%, cat hair 22.0%, dog hair 13.0% and Aspergillus fungus mix 15.0%. Asthmatic children in the group of 5- ≤ 16 years old had a rate of allergy to respiratory allergens at 85.06%  which was higher than that of asthmatic children aged 2 - ≤ 5 years old at 14.94% (p = 0.016). The incidence of allergy to respiratory allergens was higher in asthmatic children with allergic rhinitis than in the group without allergic rhinitis (p= 0.032).
