Objectives: The purpose of this study was to investigate the expression and function of IL-33 in chronic rhinosinusitis with NPs. Materials and Methods: NP tissues from 60 NP patients and normal tissues...

... on gender, polyp presence, CT scan, and VAS scores for symptoms. Results: There were 3 clusters: the first cluster comprised 37 female patients with CRS without nasal polyps (CRSsNP), the second cluster comprised 30 patients with CRS and NP (CRSwNP; 15 males and 15 females); and third cluster had 30 male...

... with allergic state and tissue remodeling. Methods: Patients were enrolled and divided into the following groups: CRS without nasal polyps (NP) without allergic rhinitis (AR) (CRSsNPsAR; n = 20), CRS with NP with AR (CRSwNPwAR; n = 20), CRS with NP without AR (CRSwNPsAR; n = 20), and controls ( n = 15). Tissue...

...Wenting Lee; Lihong Chang; Zizhen Huang; Jiancong Huang; Luoying Yang; Zhiyuan Wang; Gehua Zhang Background/Aims: To examine whether γδ T cell is expressed in the nasal mucosa of chronic rhinosinusitis (CRS) patients and its potential association with recurrence of nasal polyps. Methods: Thirty-six...

...Xi Chen; Xi Luo; Miaomiao Han; Xingmei Wu; Jiebo Guo; Jia Zhang; Haocheng Tang; Kejun Zuo; Geng Xu; Huabin Li Objective: To evaluate the regulatory effect of corticosteroid on occludin expression in polyp tissues of chronic rhinosinusitis with nasal polyps (CRSwNP) patients and in vitro. Methods...

...H. Hallén; P. Graf; J.E. Juto Nasal polyposis is a common clinical problem. The polyps commonly arise from the ethmoid sinuses and the etiology is still poorly understood. There is a connection between nasal polyps and asthma, cystic fibrosis and aspirin intolerance, but it is unclear whether...

...A.G. Kühn; W. Arnold The presence of neuropeptide-containing sensory, parasympathetic and sympathetic nerves in human nasal mucosa is well established. However, information regarding the neuropeptide distribution in nasal polyps is still lacking. The aim of this study was to compare...

...Yoshihiro Ohashi; Yoshiaki Nakai; Junko Nakata; Shoko Kihara; Hiroshi Ikeoka Immunologic conditions were studied in 8 patients with nasal allergies and nasal polyps and in 20 patients with nasal polyps. The present study showed the following: (1) Nasal polyp mucosa contains a low level of mucosal...

...Klaus W. Albegger There is evidence from many functional studies, that lymphocytes and macrophages can cooperate during the immune response. In human nasal polyps, cell clusters were demonstrated which consisted mainly of macrophages and lymphoid cells. Within the clusters, the cells showed...

...Jing Ye; Hongmeng Yu; Wolfgang Draf; Chunquan Zheng; Dehui Wang Objective: To perform the anterior-to-posterior-to-anterior technique in revision endoscopic sinus surgery, and to assess the effects and safety of this technique in treating recurrent chronic sinusitis and nasal polyps. Methods: One...

... = 0.0002; estimate, –4.2094), nasal polyps (p = 0.0007; estimate, –3.6393) and history of surgery (p < 0.0001; estimate, –5.0938) were found to reach a statistically significant level. Conclusions: We propose that allergy, polyps and history of surgery might be significant indicators of poor prognosis...

... with nasal polyps (CRSwNP). The objectives of this study are (1) to demonstrate directly the presence of staphylococcal exotoxins in nasal mucosa and sinonasal polyp tissue, and (2) provide indirect evidence of the effect of superantigens on the T cells expressing the target of superantigen, i.e., the β...
