Abstract
The present study evaluated the safety and efficacy of dupilumab in severe uncontrolled type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). A retrospective analysis was conducted on a cohort of adult patients affected by severe CRSwNP treated with dupilumab. Maxillofacial computed tomography, evaluation of blood eosinophils and serum IgE levels, measurement of nasal polyp score (NPS), smell identification test (SSIT-16), sinonasal outcome test-22 (SNOT-22) and asthma control test (ACT) were performed. Follow-up was conducted at 2 weeks, and at 1, 3, and 6 months. Adverse events and the efficacy of treatment were monitored. 23 patients were enrolled. After 15 days, scores of the SNOT-22, NPS and SSIT-16 significantly improved. These outcomes were also maintained after 1, 3, and 6 months (p < 0.001). At this latter follow-up time, SNOT-22 showed a change of -33.10 (p < 0.001), NPS -3.36 (p < 0.001) and SSIT-16 +5.60 (p < 0.001). In all, 26.1% of patients experienced early minor complications. In the present study, dupilumab was effective in the treatment of severe uncontrolled CRSwNP, demonstrating a quick significant improvement in both questionnaires and endoscopic evaluation. Only minor complications were observed.
