목적: Around 5-12% of the general population worldwide experience chronic rhinosinusitis (CRS) daily. CRS frequently coexists with allergic rhinitis and other respiratory illnesses. However, the contributions of allergies as co-morbidity vary in some literature. The objective of this study was to identify the profile of allergic rhinitis in CRS patients and establish any allergy characteristics within various phenotypes of the condition. 방법:A retrospective study at a tertiary hospital was conducted. According to the history and clinical examination, patients were classified as having CRS with nasal polyp (CRSwNP) or without nasal polyp (CRSsNP). Skin prick tests against common allergens were performed on all patients. The 22-item Sino-Nasal Outcome Test (SNOT-22), Lund-Mackay (LM) score of computed tomography scan of paranasal sinuses, and allergic rhinitis symptoms were evaluated. 결과:A total of 14 patients were enrolled 6 CRSwNP patients and 8 CRSsNP patients. Twelve (85.71%) of the patients had positive skin prick tests for at least one of the common allergens. The most common aeroallergen sensitivity was seen with house dust mites in 11 (91.67%) patients. Patients of CRSwNP with atopy had higher mean Lund Mackay score and SNOT-22 score than CRSsNP with atopy and nonatopic patients which was statistically significant. 결론:The prevalence of allergy is high in CRS patients. The clinical and radiological disease burden is greater in CRS with allergy. The protocol for diagnosing CRS should include testing for allergy sensitivity. For a better result, allergies must be treated as effectively as possible.
