Biologic therapy is a new treatment option for patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Currently, the only biologic with Food and Drug Administration–approval status for CRSwNP is dupilumab. Several other biologics are likely to be approved for CRSwNP, including mepolizumab and omalizumab, based on their promising phase 3 trial results. The role of biologics in the treatment paradigm requires consideration of multiple factors that have yet to be clearly established. This includes identifying patients most appropriate for biologic therapy while considering long-term safety and cost-effectiveness in the context of patient preferences and goals.

Abstract Background Let-7a-5p is demonstrated to be a tumor inhibitor in nasopharyngeal carcinoma. However, the role of let-7a-5p in chronic rhinosinusitis with nasal polyps (CRSwNP) has not been reported. This study is designed to determine the pattern of expression and role of let-7a-5p in CRSwNP. Methods The expression level of let-7a-5p, TNF-α, IL-1β, and IL-6 in CRSwNP tissues and cells were detected by RT-qPCR. Western blot assay was carried out to measure the protein expression of the Ras-MAPK pathway. Dual luciferase reporter assay and RNA pull-down assay were used to explore the relationship between let-7a-5p and IL-6. Results Let-7a-5p was significantly downregulated in CRSwNP tissues and cells. Moreover, the mRNA expression of TNF-α, IL-1β and IL-6 was increased in CRSwNP tissues, while let-7a-5p mimic inhibited the expression of TNF-α, IL-1β and IL-6. Besides that, let-7a-5p was negatively correlated with TNF-α, IL-1β and IL-6 in CRSwNP tissues. In our study, IL-6 was found to be a target gene of let-7a-5p. Additionally, let-7-5p mimic obviously reduced the protein levels of Ras, p-Raf1, p-MEK1 and p-ERK1/2, while IL-6 overexpression destroyed the inhibitory effect of let-7a-5p on the Ras-MAPK pathway in CRSwNP. Conclusion We demonstrated that let-7a-5p/IL-6 interaction regulated the inflammatory response through the Ras-MAPK pathway in CRSwNP.

The aim of this paper is to present an up-to-date information about therapeutical options in chronic rhinosinusitis with nasal polyps. First choice therapy is a long term regular application of intranasal steroids in combination with salinic solution douches. If this treatment is not eff ective enough, then the pulses of systemic steroids are indicated. If the sufficient control of the disease is not achieved, then surgery is a therapeutic choice; it means functional endoscopic sinus surgery in the extent corresponding to the extension of the sinus disease. However, there remains a certain group of patients in whom the results with this treatment are not optimal. The type 2 immunopathological response affects relevantly the course of the disease. Nowadays, the research is done in this field. Specific agents, which are able to block circulating inflammatory mediators or bind receptors for these mediators are developed and studied. The results of the studies having been completed by now are promising. Keywords: biological therapy – chronic rhinosinusitis – nasal polyps – dupilumab – immunoglobulin E – interleukin
