ARIA분류에 따른 알레르기 비염의 유병률 = Prevalence of Allergic Rhinitis on the Basis of ARIA Classification

다국어 초록 (Multilingual Abstract)

Background and Objectives：Allergic rhinitis (AR) is commonly sub-classified into seasonal and perennial rhinitis. The recent “Allergic Rhinitis and its impact on Asthma (ARIA) Workshop” proposed to replace these terms by intermittent vs persistent AR. But the validity of this new classification is still largely unknown. Subjects and Method：Three hundred-eleven allergic rhinitis patients were included in this study. Patients were categorized into seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR) groups, according to sensitized allergens. Twenty-eight items questionnaire filled out by patients were designed for this study. Based on the questionnaire, patients were classified into either intermittent or persistent AR. Patients information and associated factors were analysed between the groups. Results：Within the population with AR, 58% of the subjects had persistent AR. About 41% of the patients were classified as moderate-severe persistent AR. There was no association between the intermittent/persistent and the SAR/PAR classifications. Subjects with persistent AR had more severe symptoms, higher rate of self-awareness and had been previously diagnosed with AR. There were no significant difference in sensitization to allergens. However, grass, tree, house dust mite allergy is more common in persistent AR than in intermittent AR. More patients in Blockers and Mixed groups had persistent AR. Conclusion：A statistical comparison of the two classifications showed that they cannot be used interchangeably, as they do not represent the same stratum of disease. There is also an evidencethat the persistent type describes a distinct group with characteristics that differentiates them from intermittent AR. These results support the validity of the new ARIA classification as shown in other studies. (Korean J Otolaryngol 2006;49:623-8)
