Insights
House dust mites are the primary allergen in children with allergic rhinitis (AR) and those with both asthma and AR. This study highlights common aeroallergens in pediatric respiratory diseases.
Area of Science:
- Pediatric Allergy and Immunology
- Environmental Health
- Respiratory Medicine
Background:
- Climate change may impact allergic sensitization in children.
- Understanding aeroallergen prevalence is crucial for managing pediatric respiratory conditions.
Purpose of the Study:
- To compare aeroallergen sensitization prevalence in children with allergic rhinitis (AR) versus those with both asthma and AR.
- To identify common allergens in pediatric patients with respiratory allergies.
Main Methods:
- Cross-sectional study of 216 children (aged 2-17) diagnosed with AR or asthma/AR.
- Review of medical records and sensitization test results from January 2020 to December 2023.
- Descriptive statistical analysis to compare sensitization patterns between groups.
Main Results:
- No significant difference in monosensitization rates between AR and asthma/AR groups (20.8% overall).
- House dust mites were the most prevalent allergen in both groups.
- Cockroach, cat epithelium, oak, and ash pollen were also common, with no significant group differences.
Conclusions:
- House dust mite sensitization is predominant in children with AR and asthma/AR.
- Findings contribute to understanding major aeroallergens in pediatric respiratory diseases.
- Identified key allergens for targeted interventions in pediatric allergic respiratory conditions.
Introduction:
Climate change may influence patterns of allergic sensitization in children.
Objective:
To compare the prevalence of aeroallergen sensitization in pediatric patients diagnosed with allergic rhinitis (AR) alone versus those diagnosed with both asthma and AR (asthma/AR).
Methods:
A cross-sectional study was conducted at a teaching hospital. Medical records of children aged 2-17 years, diagnosed with AR or asthma between January 2020 and December 2023, and with at least one positive sensitization test, were reviewed. Descriptive statistical analyses were performed for all study variables.
Results:
A total of 216 children were included (mean age, 8.4 years; 65.7% male), divided into two groups: AR (107 cases) and asthma/AR (109 cases). Overall, 45 patients (20.8%) were monosensitized, with no significant difference between groups (p = 0.364). House dust mites were the most frequent allergens in both groups (p = 0.992), followed by cockroach and cat epithelium. Among pollens, oak and ash were the most common, with no significant differences between groups (all p > 0.05).
Conclusion:
Sensitization to house dust mites predominated in both AR and asthma/AR patients. These findings contribute to current knowledge of the major aeroallergens involved in allergic sensitization among children with respiratory diseases.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
