Abstract: Objective  To observe the effect of dexamethasone (DEX) on the production of chemokines in nasal polyp tissue of patients with chronic sinusitis with nasal polyps (CRSwNP). Methods  Dispersed nasal polyp cells were prepared from nasal polyp tissues of CRSwNP patients and then the cells were treated with 10, 50 and 100 μmol/L DEX. The cell viability and levels of chemokines in cell culture supernatant were detected 24 h after DEX treatments. Results  Compared to the untreated group, the percentage of viable cells in the 10, 50 and 100  μmol/L DEX-treated groups were unchanged. The levels of CCL2, CCL11, CXCL2 and CXCL9 were significantly lower, CCL20 significantly higher, CCL3,CCL4, CCL5, CCL17 and CXCL5 unchanged.Conclusion  DEX reduced the production of multiple chemokines in dispersed nasal polyp cells of nasal polyp tissue, which may inhibit infiltration of inflammatory cells and occurrence of inflammatory response.
