Nasal cytology as a reliable non-invasive procedure to phenotype patients with type 2 chronic rhinosinusitis with nasal polyps

World Allergy Organization Journal, 2022
Background: The identification of type-2 inflammation in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) acquires a crucial role in the endotypization needed for selecting patients for biological drugs targeting type-2 inflammation: to ...

Environmental Exposures, Chronic Sinusitis, and Olfaction in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Environmental air pollutants may contribute to chronic rhinosinusitis (CRS), but their relationship with upper airway disease in people with cystic fibrosis (CF) remains poorly understood. This study evaluated associations between long‐term ambient air pollutant exposure and CRS severity and olfactory dysfunction in adults with CF ...

Expression Levels of Glutathione S-Transferase and Cytochrome P450 Isoenzymes in Nasal Polyp Tissue

, 2022
Nasal polyps are benign sinonasal masses composed of eosinophils and extracellular edema. Pathogenesis of the polyp formation is unclear but several studies strongly suggest a correlation with infection, inflammation and allergy conditions. Our aim is to

Tezepelumab in Chinese Patients With Severe Chronic Rhinosinusitis With Nasal Polyps: A Prespecified Subgroup Analysis of the Phase 3 WAYPOINT Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) in Chinese patients often exhibits a mixed Type 1/2/3 inflammatory phenotype (63%), potentially impacting the efficacy of biologics targeting Type 2 inflammation. This prespecified subgroup analysis of WAYPOINT (NCT04851964) evaluated the efficacy and safety of tezepelumab in Chinese

Expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 in recurrent chronic rhinosinusitis with nasal polyposis

Kaohsiung Journal of Medical Sciences, 2013
Matrix metalloproteinase (MMP) is involved in the upper airway remodeling process. We hypothesized that MMP had an additive effect on the formation of recurrent nasal polyp.

Inflammatory Signatures Beyond Th1/Th2 Endotypes Provide Insights Into Postoperative Recurrence in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) represents a spectrum of inflammatory endotypes, driven by distinct T helper (Th) immune responses. The high rate of recurrent disease despite appropriate medical and surgical interventions highlights the need for improved characterization beyond the traditional type 2 and non‐type 2 phenotypes to better
