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.PMID:41510924 | DOI:10.15586/aei.v54i1.1536
