Abstract: BACKGROUND: Evidence linking adenoid hypertrophy (AH) and atopy is conflicting. We examined whether Cassano-graded AH severity is more closely associated with inflammatory markers than with IgE-mediated sensitization. METHODS: We retrospectively included children aged 3-12 years diagnosed with AH between December 2022 and December 2025. AH was graded according to the Cassano classification and dichotomized as advanced AH (Stage III-IV). Atopic features were evaluated separately as clinical atopy, IgE-mediated sensitization, elevated total IgE, and eosinophilia. Multivariable logistic regression analyses were performed to assess factors associated with clinical atopy, sensitization, and advanced AH. RESULTS: Among 426 children, clinical atopy was present in 28.2%, sensitization in 23.0%, elevated total IgE in 16.4%, and eosinophilia in 27.7%; 39.2% had advanced AH. In multivariable analysis, clinical atopy was independently associated with family history of atopy (aOR 13.9; 95% CI 7.9-24.4), elevated total IgE (aOR 3.86; 95% CI 2.10-7.08), and passive smoking exposure (aOR 1.73; 95% CI 1.07-2.79). Sensitization was independently associated only with family history of atopy (aOR 4.99; 95% CI 1.99-12.53). Advanced AH was independently associated only with eosinophilia (aOR 2.07; 95% CI 1.30-3.29). CONCLUSIONS: AH severity was associated with eosinophilia rather than classical IgE-mediated sensitization. Assessment of eosinophilia may aid routine severity evaluation in children with AH.
