Purpose: Dupilumab represents an innovative and effective therapy for refractory/recurrent severe chronic rhinosinusitis with nasal polyps (CRSwNP). Intranasal corticosteroids should be used during treatment with biological agents. However, adherence to nasal therapy may not be complete. The aim of this study was to evaluate the role of intranasal corticosteroids in patients with CRSwNP who underwent treatment with dupilumab.Materials and methods: Fifty-two patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, blood eosinophils, Nasal Polyp Score - NPS, Visual Analogue Scale - VAS - for smell loss, Asthma Control Test - ACT), quality of life (Sino Nasal Outcome Test 22 - SNOT-22 questionnaire), nasal cytology, and adherence to regular administration of intranasal corticosteroids were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3).Results: NPS, VAS for smell, ACT and SNOT-22 total score and subscores improved during treatment (p < 0.05). Blood eosinophils reached a peak at T1-T2 and then decreased toward baseline at T3. Adherence to regular treatment with intranasal steroids was 61.5 %. No statistically significant differences in all the clinical outcomes were observed between patients who regularly used intranasal steroids and other subjects (p > 0.05). Nasal cytology showed a decrease of eosinophils and an increase of neutrophils during treatment.Conclusions: Dupilumab is still effective in patients who are using topical nasal steroids with variable adherence (real world settings).

Abstract
Purpose: Dupilumab represents an innovative and effective therapy for refractory/recurrent severe chronic rhinosinusitis with nasal polyps (CRSwNP). Intranasal corticosteroids should be used during treatment with biological agents. However, adherence to nasal therapy may not be complete. The aim of this study was to evaluate the role of intranasal corticosteroids in patients with CRSwNP who underwent treatment with dupilumab.Materials and methods: Fifty-two patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, blood eosinophils, Nasal Polyp Score - NPS, Visual Analogue Scale - VAS - for smell loss, Asthma Control Test - ACT), quality of life (Sino Nasal Outcome Test 22 - SNOT-22 questionnaire), nasal cytology, and adherence to regular administration of intranasal corticosteroids were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3).Results: NPS, VAS for smell, ACT and SNOT-22 total score and subscores improved during treatment (p < 0.05). Blood eosinophils reached a peak at T1-T2 and then decreased toward baseline at T3. Adherence to regular treatment with intranasal steroids was 61.5 %. No statistically significant differences in all the clinical outcomes were observed between patients who regularly used intranasal steroids and other subjects (p > 0.05). Nasal cytology showed a decrease of eosinophils and an increase of neutrophils during treatment.Conclusions: Dupilumab is still effective in patients who are using topical nasal steroids with variable adherence (real world settings).
