- Abstract
Background: Biologic agents are considered a new revolutionized therapy for severe and recurrent forms of CRSwNP which disease burden is not sufficiently controlled by conservative and/or surgical treatments. Recent Research has focused on evaluating their real-life efficacy in CRSwNP, as only limited reports on real-life data are available. However, in most studies, the response to treatment is evaluated in terms of improvement in Nasal Polyp Score (NPS) or in Sino-Nasal Outcome test (SNOT-22) scores. However, both criteria do not consider nasal immunophlogosis, which can be easily assessed by nasal cytology. The aim of our study was to evaluate changings in the nasal inflammatory infiltrate of CRSwNP patients treated with Dupilumab for 12 months., Methods: 27 patients suffering from severe CRSwNP treated with Dupilumab were recruited. Nasal cytology findings, NPS, SNOT-22, ACT scores and blood eosinophil count at T0 (before treatment) and at T1 (after 1 year of treatment) were compared., Results: After 1 year of biological therapy with Dupilumab, NPS, SNOT-22 and, among the 17 asthmatic patients, ACT scores improved significantly. At T1, a statistically significant percentage of patients showed negative citology. Moreover, a significant reduction in the mast cell-eosinophilic pattern and an increase of neutrophils and bacteria was reported., Conclusions: The response to treatment can be considered both in the case of negative nasal cytology and in the case of the appearance of neutrophils and bacteria. In this context, eosinophils, the specific target of biological therapies, play a crucial role in regulating tissue homeostasis and, consequently, the nasal immunophlogosis., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 The Authors.
