Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by persistent symptoms associated to the development of nasal polyps. To this day, the molecular mechanisms involved are still not well defined. However, it has been suggested that a sustained inflammation as allergy is involved in its onset. In this exploratory study, the aim was to investigate the effect of the allergic status in the development of CRSwNP. To achieve this, we recruited 22 patients with CRSwNP and classified them in non-allergic and allergic using ImmunoCAP ISAC molecular diagnosis. Plasma samples were analyzed using liquid chromatography coupled to mass spectrometry (LC-MS). Subsequently, significant metabolites from plasma that were commercially available were then analyzed by targeted analysis in some nasal polyps. Additionally, nasal polyp and nasal mucosa samples were examined for eosinophils, neutrophils, CD3+ and CD11c+ cells, as well as collagen deposition and goblet cell hyperplasia. We found that 9 out of the 22 patients were sensitized to some aeroallergens (named as allergic CRSwNP). The other 13 patients had no sensitizations (non-allergic CRSwNP). Regarding metabolomics, bilirubin, cortisol, lysophosphatidylcholines (LPCs) 16:0, 18:0 and 20:4 and lysophosphatidylinositol (LPI) 20:4, which are usually related to a sustained allergic inflammation, were unexpectedly increased in plasma of non-allergic CRSwNP compared to allergic CRSwNP. LPC 16:0, LPC 18:0 and LPI 20:4 followed the same trend in nasal polyp as they did in plasma. Comparison of nasal polyps with nasal mucosa showed a significant increase in eosinophils (p < 0.001) and neutrophils (p < 0.01) in allergic CRSwNP. There were more eosinophils in polyps of non-allergic CRSwNP than in their nasal mucosa (p < 0.01). Polyps from non-allergic CRSwNP had less eosinophils than the polyps of allergic CRSwNP (p < 0.05) and reduced amounts of collagen compared to their nasal mucosa (p < 0.001). Our data suggests that there is a systemic inflammatory response associated to CRSwNP in the absence of allergy, which could be accountable for the nasal polyp development. Allergic CRSwNP presented a higher number of eosinophils in nasal polyps, suggesting that eosinophilia might be connected to the development of nasal polyps in this phenotype.

Role of NLRP3 Inflammasome in Eosinophilic and Non-eosinophilic Chronic Rhinosinusitis with Nasal Polyps. Inflammation 2017; 39:2045-2052.

Abstract
The pathophysiologic mechanisms of human chronic rhinosinusitis with nasal polyps (CRSwNP) remain unclear. We aimed to elucidate expression and biologic role of NLRP3 inflammasome in CRSwNP. Immunohistochemistry (IHC) was conducted to assess NLRP3 immunolabeling, real-time polymerase chain reaction (PCR) was used for IL-9 and NLRP3, and caspase-1 level quantitation in CRSwNP and control subjects. In addition, enzyme-linked immunosorbent assay (ELISA) was employed for analyzing concentrations of IL-1β and IL-18 in the homogenates prepared from tissue specimens. Moreover, human nasal epithelial cells (HNECs) were used to evaluate the effects of lipopolysaccharide (LPS) and glyburide on NLRP3 inflammasome signaling pathway. Results showed that NLRP3 and caspase-1 were overexpressed in CRSwNP, especially in eosinophilic CRSwNP (ECRSwNP). Interestingly, NLRP3 expression had close correlation to that of caspase-1. Concentrations of IL-1β and IL-18 were elevated. NLRP3 inflammasome signaling pathway was augmented by LPS but suppressed by glyburide. In conclusion, NLRP3 inflammasome signaling pathway played a pro-inflammatory role in the pathogenesis of CRSwNP, especially in ECRSwNP. NLRP3 inflammasome signaling pathway was augmented by LPS, but suppressed by glyburide.
