[Prevalence of allergy in children with acute rhinosinusitis].

Objective:To explore the prevalence of allergy in patients with acute rhinosinusitis (ARS) and evaluate the severity of symptoms in ARS children with or without allergy.Method:Two hundred and seven children (4-12 years of age) with ARS and 85 children of control group were included in our research from June, 2016 to January, 2018. We use questionaire to collect the basic information of pediatric patients. The results of skin prick test (SPT) were recorded. Mothers were required to complete the Sinus and Nasal Quality-of-Life Survey (SN-5).All ARS childern were divided into allergic group and non-allergic group according to the result of SPT. We use binomial distribution to evaluate the population rate. t-test, Chi-square test and Wilcoxon rank-sum test were appropriately used to compare the parameters between two groups.Result:Among the 207 ARS participants in this study, 44.4% participants were shown to response to at least one Inhalation allergen and 40.6% participants were shown to response to at least one perennial allergen. Both ratios were significantly higher than those of the control group. Perennial allergy seems to be much more common than seasonal allergy in pediatric patients with ARS. The most troublesome symptoms among the participants with acute rhinosinusitis combined with allergic rhinitis were nasal obstruction (5.28±1.34), nasal discharge (5.07±1.04), post-nasal drip (4.63±1.31) and itchy eyes/nose (4.28±1.51). Four subscale scores of the SN-5 including nasal obstruction, allergy symptoms, emotional distress and activity limitation in the allergic group were obviously higher than those of the non-allergic group.Conclusion:Allergic factors play an important role in the pathogenesis of pediatric acute rhinosinusitis.
