Background and Objectives: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disease resulting from inflammation of the nasal cavity and paranasal sinuses. Systemic allergic inflammation is an important cause of CRSwNP; however, the effect of local allergic inflammation is unclear. This study was designed to investigate the effect of local allergic inflammation in CRSwNP.
Materials and Methods: The study included 11 patients with CRSwNP and 18 control subjects. Olfactory function was measured with the Korean Version of Sniffin’s stick test. Nasal lavage fluids (NLFs) were collected from all subjects and analyzed for total IgE, eosinophilic cationic protein (ECP), and cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-4, IL-10, IL-17A, interferon-γ). Flow cytometry was used to measure various inflammatory cells in the NAL fluids.
Results: On analysis of flow cytometry and enzyme-linked immunosorbent assay, we found that CRSwNP patients had significantly increased eosinophil (%) and ECP levels in NLFs. In addition, there was significant local-systemic correlation between ECP level in NLFs and blood eosinophils (%) (r=0.391); however, there was no significant association between eosinophils (%) in NLFs and blood eosinophils. Moreover, in CRSwNP patients, the severity of disease was related with blood eosinophil (%), eosinophil (%), and ECP levels in NLFs, whereas olfactory function was associated with blood eosinophil (%) and ECP levels in NLFs.
Conclusion: CRSwNP is a disease with high allergic inflammation that has negative impacts on the severity of disease and olfactory function. Therefore, we suggest that control of local allergic inflammation will be helpful to treat CRSwNP patients.
