Effects of Omalizumab Treatment in Patients With Recalcitrant Nasal Polyposis and Mild Asthma: A Multicenter Retrospective Study

2021

Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a clinical entity with specific features that impacts significantly on patient quality of life (QoL). CRSwNP is often associated with asthma and is difficult to control and manage despite pharmacological and/or surgical treatment. Omalizumab, a monoclonal anti-IgE antibody, has emerged as a putative therapeutic option. Objective To evaluate the effects of omalizumab on nasal polyp (NP) size and QoL assessed by Sino-Nasal Outcome Test-22 (SNOT-22) in patients with recalcitrant CRSwNP and mild asthma. Methods A multicenter retrospective analysis of patient data from the Community of Valencia (Spain) was performed. Adult patients …

Chronic rhinosinusitis with nasal polyps impact in severe asthma patients: Evidences from the Severe Asthma Network Italy (SANI) registry

2020

Abstract Background The clinical and laboratory features of patients enrolled in the Severe Asthma Network in Italy (SANI) registry, a web-based observatory collecting demographic, clinical, functional and inflammatory data of patients with severe asthma were evaluated, with a special emphasis to chronic rhinosinusitis with nasal polyposis (CRSwNP). Methods For each eligible patients the following information has been collected: demographic data, clinical features, asthma control in the previous month according to the GINA (Global INitiative for Asthma) Guidelines and standardized questionnaires, concomitant regular and on demand treatments and inflammatory markers. Results 695 patients wit…

The Severe Asthma Network in Italy: Findings and Perspectives

2019

Background Severe Asthma Network in Italy (SANI) is a registry of patients recruited by accredited centers on severe asthma. Objective To analyze epidemiological, clinical, inflammatory, functional, and treatment characteristics of severe asthmatics from the SANI registry. Methods All consecutive patients with severe asthma were included into the registry, without exclusion criteria to have real-life data on demographics, asthma control, treatments (including biologics), inflammatory biomarkers, and comorbidities. Results A total of 437 patients (mean age: 54.1 years, 57.2% females, 70.7% atopics, 94.5% in Global Initiative for Asthma severity step V) were enrolled into the study. The mean …

Notch‐1 signaling activation sustains overexpression of interleukin 33 in the epithelium of nasal polyps

2019

Abstract BACKGROUND: Alterations in the nasal epithelial barrier homeostasis and increased interleukin 33 (IL-33) expression contribute to the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). AIMS: As Notch-1 signaling is crucial in repair processes of mucosa, the current study assessed Notch-1/Jagged-1 signaling and IL-33 in the epithelium of nasal polyps biopsies from allergic (A-CRSwNP; n = 9) and not allergic (NA-CRSwNP; n = 9) subjects by immunohistochemistry. We also assessed, in a model of nasal epithelial cells, the effects of stimulation of Notch-1 with Jagged-1 on the expression of IL-33 (by flow cytometry, immunofluorescence, and immunocytochemistry), Jagged-1 (…

Increased expression of IL-19 in the epithelium of patients with chronic rhinosinusitis and nasal polyps.

2012

Background : Chronic rhinosinusitis (CRS) is an inflammation of the nose and of the paranasal sinuses. The involvement of the respiratory epithelium in the mechanisms of CRS is poorly understood. Aims : Among proteins expressed by nasal epithelial cells in CRS, IL-19 may have key functions. We here aimed to determine the expression and regulation of IL-19. Methods : Nasal biopsies from normal subjects (n = 12), subjects with CRS but without nasal polyps (NP) (CRSsNP, n = 12) and with CRS with NP (CRSwNP, n = 15) were collected. Human Asthma Gene Array and real-time PCR were used to evaluate gene expression, western blot analysis and immunohistochemistry for protein expression. Results for I…
