Overview
Brief Summary
Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a complex chronic inflammatory disease of the nasosinusal mucosa that has a significant negative impact on patients' quality of life.
In CRSwNP, chronic inflammation is primarily driven by type 2 pro-inflammatory interleukins (ILs )such as IL-5, IL-4, and IL-13 along- side high levels of eosinophils in the surrounding tissue. Mepolizumab is a targeted, humanized anti-IL-5 antibody that prevents IL-5 from binding to its receptor on eosinophils and selectively inhibits eosinophilic inflammation.
So far, randomized clinical trials have assessed efficacy and safety of Mepolizumab in a large number of patients, whereas evidences in real life clinical practice are limited to few monocentric series.
Herewith, we present a multicenter, observational, prospective/retrospective nationwide real-life study with the aim to confirm the effectiveness and the safety of Mepolizumab over the first year of treatment in a real life setting.
The primary objective of this study is to evaluate the reduction of dimension of nasal polyps and the improvement of quality of life in the patient measured through symptomatologic questionnaires.
The secondary objective is to evaluate improvements in terms of smell dysfunction, comorbidities, biomarkers (nasal cytology and blood eosinophilia), need of surgery or systemic steroids.
