RESUMO
OBJECTIVE: To determine the prevalence of allergic symptoms in children with otitis media with effusion (OME). STUDY DESIGN: A validated questionnaire from the International Study of Asthma and Allergies in Childhood was used to determine the prevalence of allergic symptoms in children. The questionnaire was completed by the parents of children with OME undergoing ventilation tube insertion, and the results were compared with a large reference group of school children of the same age. SUBJECTS AND METHODS: Children aged 6 or 7 years old with OME confirmed intraoperatively during ventilation tube insertion between 2001 and 2005 (n=89). The prevalence of allergic symptoms and nasal symptoms in children with OME was compared with an age-matched reference group. RESULTS: There was no difference in the prevalence of allergic symptoms suggesting rhinoconjunctivitis, asthma, or eczema between the OME and reference group. The prevalence of nasal symptoms, however, was greater in the children with OME than in the reference group 38.2 percent versus 23.5 percent (odds ratio=2.01; 95% confidence interval, 1.30-3.10; P<0.001). CONCLUSION: The prevalence of allergic symptoms was similar in 6- to 7-year-old children with OME and the reference group, suggesting a limited effect of allergy in the pathogenesis of OME in this age group. Nasal symptoms were more common in the OME group, which may reflect a higher prevalence of adenoidal hyperplasia.
