Abstract:
Background Nasal polyps accompany eosinophilic chronic rhinosinusitis (ECRS). Cytokines, including interleukin (IL)-25, IL-33, and thymic stromal lymphopoietin (TSLP) expressed in nasal mucosa have been implicated in polyp pathogenesis. We investigated the role of nasal polyp epithelium cytokine expression in eosinophilic infiltration in ECRS. Methods Tissues were collected from 39 patients undergoing nasal surgery. Cases were divided into 3 groups: control (CTR), non-ECRS (nECRS), and ECRS and were evaluated for IL-25, IL-33, and TSLP expression. Results Abundant eosinophilia was observed underneath the nasal mucosa and around the nasal ducts in polyps in ECRS and correlated positively with IL-33 protein expression. Conclusion Cytokine expression in nasal duct cells and eosinophilic infiltration around duct cells similar to those in the nasal mucosa occurred in the nasal epithelium of polyps, suggesting its role in inducing eosinophilic inflammation.

Abstract:
AbstractBackground:Most patients with nasolacrimal duct obstruction have dry, crusty nasal mucosa. Mucociliary clearance is modulated by the amount and biochemical composition of nasal mucus. Nasolacrimal duct obstruction disturbs the drainage of tears into the nasal cavity.Objective:We examined the effect of nasolacrimal duct obstruction on the mucociliary transport of nasal mucosa, by comparing saccharine test results for epiphora patients versus healthy volunteers.Study design:Prospective, randomised, clinical trial.Methods:Eight patients with bilateral epiphora and 10 patients with unilateral epiphora were included in the study group. Complete nasolacrimal duct obstruction was demonstrated by studying irrigation of the nasolacrimal system, and by fluorescein dye study. The control group comprised 20 healthy volunteers. Mucociliary transport was assessed by the saccharine test in both the study and control groups. The saccharine transit times of 26 impaired nasal cavities were compared with those of 20 healthy nasal cavities of controls. Also, the saccharine transit times of the healthy nasal cavities of the 10 patients with unilateral epiphora were compared with those of their diseased sides, and also with those of healthy volunteers.Results:The saccharine transit times of the epiphora patients were statistically significantly greater than those of the control group. Also, there was a statistically significant difference in saccharine transit times, comparing the healthy and impaired nasal cavities of patients with unilateral epiphora.Conclusion:Nasolacrimal duct obstruction has a negative effect on nasal mucociliary clearance. This may be related to changes in the amount and biochemical composition of nasal mucus.
