[Progress and prospects of anti-IL-4/IL-13 monoclonal antibody treatment in chronic rhinosinusitis with nasal polyps].

Chronic rhinosinusitis（CRS） is a chronic inflammation of the nasal cavity and sinus mucosa, which is mainly characterized by nasal obstruction, runny nose, headache and hyposmia. Due to complex mechanisms, CRS can be divided into different clinical phenotypes and inflammatory endotypes. Approximately 80% of chronic rhinosinusitis with nasal polyps（CRSwNP） patients present with type Ⅱ inflammation. IL-4 and IL-13 are the key factors in the process of type Ⅱ inflammation, and drugs targeting IL-4/IL-13 provide new options for the treatment of CRSwNP. Therefore, this article mainly reviews the application of anti-IL-4 /IL-13 monoclonal antibody in CRSwNP.
