Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) may have a heterogeneous response to medical/surgical treatments based on endotypes. Data correlating biomarkers and severity of the disease are lacking. We aimed to determine if IL-5 and calprotectin may be useful in defining severity of disease and identifying uncontrolled patients. METHODS This was a case-control study including 81 patients with diffuse CRSwNP who underwent at least one previous surgery and treated with intranasal steroids. We enrolled 39 uncontrolled patients (SNOT-22 ≥ 40 and two or more cycles of systemic corticosteroids in last year) (Group A) and 42 controlled one (SNOT-22 < 40 and less than two cycles of systemic corticosteroids in last year) (Group B). We analyzed IL-5 and calprotectin in both nasal secretions and nasal polyp tissue. RESULTS Calprotectin and IL-5 were significantly higher in Group A in both secretions and tissue, and the higher the number of previous surgeries, the higher the levels detected in nasal secretions. At univariate analyses, smoking, asthma, non-steroidal anti-inflammatory drugs-exacerbated respiratory disease (NSAID-ERD), blood eosinophilia, neutrophils, and eosinophils at nasal cytology were significantly associated with uncontrolled disease. Multivariate analyses showed that asthma, NSAID-ERD, and IL-5 in nasal secretion/polyp tissue were significantly related to the risk of uncontrolled disease. CONCLUSIONS Our data suggest that asthma, NSAID-ERD, and IL-5 in nasal secretions/tissue may be helpful to identify more severe patients, as they are related to the risk of uncontrolled disease. Nonetheless, high levels of calprotectin and neutrophilia were also observed in uncontrolled patients, especially after multiple surgeries.

Abstract
BACKGROUND Although altered eicosanoid levels are related to disease severity in chronic rhinosinusitis with nasal polyps (CRSwNP), identifying patients prone to recurrent nasal polyps (NPs) is still difficult. We investigated levels of nasally secreted eicosanoids before and after NP surgery in patients with or without NP recurrence (NPR) and explored potential endotypes based on pre-surgical eicosanoid levels. METHODS Levels of leukotriene (LT) E4 , LTB4 , prostaglandin (PG) D2 , PGE2 and 15(S) hydroxyeicosatetraenoic acid (15[S]-HETE) were measured in nasal secretions with specific immunoassays at pre-surgery (n = 38) and 6 and 12 months post-surgery (n = 35), with NPR identified endoscopically. Pre- and post-surgical levels were compared between patients with and without NPR. Eicosanoid patterns among patients were explored with cluster analysis and evaluated with clinical parameters. RESULTS Patients with recurrent NPs had pronounced pre-surgical levels of nasal 15(S)-HETE, PGD2 and LTE4 . From pre-surgery to 12 months post-surgery, NPR was associated with significant decreases of 15(S)-HETE and PGD2 relative to non-recurrence, whereas levels of LTE4 decreased at 6 months but increased again at 12 months. Clustering revealed three potential endotypes. Clusters 1 and 3 featured high and low eicosanoid levels, respectively. Cluster 2 had higher levels of LTE4 and PGD2 , lower levels of PGE2 and LTB4 , and more cases of recurrent NPs and previous NP surgeries. CONCLUSION Elevated nasal LTE4 12 months post-surgery in NP recurrent subjects suggests that postoperative LTE4 measurements may indicate rapid NP regrowth. A distinct nasal eicosanoid profile may be used for the identification of the most severe recalcitrant patients in need of targeted immunomodulatory therapies.

Abstract
OBJECTIVE The Food and Drug Administration and the National Institutes of Health (NIH) have asserted that diverse demographic representation in clinical trials is essential. In light of these federal guidelines, the objective of this study is to assess the racial, ethnic, and gender demographics of patients enrolled in clinical trials registered with the NIH that evaluate chronic rhinosinusitis with nasal polyposis (CRSwNP) relative to the demographics of the US population. STUDY DESIGN Cross-sectional study. SETTING Not applicable. METHODS ClinicalTrials.gov was queried to identify all prospective clinical trials for CRSwNP. Individual study and pooled data were compared with national US census data. RESULTS Eighteen studies were included comprising 4125 patients and evaluating dupilumab, mepolizumab, omalizumab, fluticasone/OptiNose, MediHoney, mometasone, and SINUVA. Women constituted 42.7% of clinical trial participants. Of the 4125 participants, 69.6% identified as White, 6.6% as Black, 20.8% as Asian, 0.1% as Pacific Islander, 0.4% as American Indian, 8.0% as Hispanic, and 2.4% as other. The racial, ethnic, and gender composition of the pooled study population differs significantly from national US census data, with underrepresentation of Black, Hispanic, Pacific Island, and American Indian individuals, as well as females (P < .05). CONCLUSION The racial, ethnic, and gender demographics of patients enrolled in CRSwNP clinical trials registered with the NIH differ significantly from the demographics of the US population, despite federal guidelines advising demographically representative participation. Proactive efforts to enroll participants that better represent anticipated treatment populations should be emphasized by researchers, institutions, and editorial boards.

Abstract
OBJECTIVE To evaluate disease presence in the central compartment (CC) in patients with eosinophilic chronic rhinosinusitis (CRS). METHODS Patients with eosinophilic CRS were divided into three endotypes: aspirin-exacerbated respiratory disease (AERD), allergic fungal rhinosinusitis (AFRS), and eosinophilic CRS with nasal polyps (eCRSwNP). CT scans were reviewed for CC involvement, defined as the area between the superior nasal septum (SNS) and middle turbinate (MT). CC involvement was measured based on the degree of opacification (0: no opacification, 1: up to 50% opacification, and 2: >50% opacification), and distance from SNS to MT (mm). Patients who had lateralized MTs from prior surgery as the cause of CC widening were excluded. Patients who underwent orbital decompression were included as a control group. RESULTS Fifty patients in each group (AERD, AFRS, and eCRSwNP) and 50 control patients were included. Average number of surgeries was 2.5 in AERD (p = 0.05), 2 in AFRS (p = 0.4), and 1.7 in eCRSwNP. Preoperative CC distance was significantly higher in AERD versus control, AFRS, and eCRSwNP: 4.2 versus 2.8 mm (p < 0.0001), 4.2 versus 1.9 mm (p < 0.0001), and 4.2 versus 2.7 mm (p < 0.0001), respectively. Postoperatively, CC distance and degree of opacification were significantly higher in AERD versus control, AFRS, and eCRSwNP. Within the AERD group, CC distance was significantly higher postoperatively than preoperatively (6.5 vs. 4.2 mm, p = 0.002). CONCLUSION CC involvement is more significant in AERD patients and if present, rhinologists should be suspicious of the diagnosis. This area could represent a source of inflammatory load in patients with AERD.

Abstract
BACKGROUND The prevalence of eosinophilic CRSwNP in China has increased significantly over the last 20 years, noninvasive methods that could assist in diagnosis are urgently needed. AIMS The aim of this study is to explore the clinical significance of peripheral blood eosinophil in diagnosing ECRS. MATERIALS AND METHODS We conducted a prospective study of 221 patients diagnosed with CRS. Lund-Mackay score, peripheral blood eosinophil absolute count, peripheral blood eosinophil percentage were detection to compare the clinical features with ECRS and non-ECRS. ROC curve was performed to assess the efficiency of clinical index to predict ECRS. RESULTS The ECRS group of patients had significantly higher scores compared with those of the non-ECRS group. Different extent and severity of mucosal thickening on total Lund-Mackay scores, anterior ethmoidal, posterior ethmoidal and ostiomeatal complex have confirmed different blood eosinophil levels in CRS patients. The combination of peripheral blood eosinophil percentage and posterior ethmoidal score to predict ECRS was 0.807. CONCLUSIONS AND SIGNIFICANCE The increase in peripheral blood eosinophil percent indicates the deterioration the inflammation of chronic rhinosinusitis and the level of posterior ethmoidal score and peripheral blood eosinophil percentage have a positive predictive value regarding ECRS identification.

Abstract
Background Although the close relationship between the upper and lower airways has been highlighted previously, little is known about the association between lung function and the recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP). This study aimed to evaluate the factors associated with pulmonary function that affect CRSwNP recurrence after surgery. Methods We performed a series of routine pulmonary function tests for general anesthesia prior to CRSwNP surgery. The values for each parameter were compared in the presence or absence of recurrence. Results Sixty-nine patients with CRSwNP were included. The percent predicted forced expiratory volume in one second (%FEV1) in the recurrent group was significantly lower than that in the non-recurrent group (P = .005). A multivariable logistic regression model revealed that %FEV1 was a positive predictor of recurrence (odds ratio: 0.96, 95% CI: 0.92-0.99, P = .023). There were no significant differences in the other pulmonary functions between the two groups. Conclusions We found that %FEV1 may be a predictor of CRSwNP recurrence after surgery. As %FEV1 is a pulmonary function test that is routinely performed before surgery, this parameter is readily applicable. Moreover, as %FEV1 appears to have the potential to reveal concealed asthma, %FEV1 might be a particularly useful tool for the prediction of CRSwNP recurrence after surgery.

Abstract
BACKGROUND Treatment of aspirin-exacerbated respiratory disease (AERD) includes endoscopic sinus surgery (ESS) and aspirin desensitization (AD) with aspirin therapy after desensitization (ATAD). The objective of this study was to determine the rate of major complications associated with aspirin use that resulted in the discontinuation of aspirin therapy. METHODS This study was a retrospective chart review of patients with AERD who underwent ESS, AD, and ATAD at a single AERD tertiary center between July 2016 and February 2019. Complications associated with aspirin that resulted in the discontinuation of aspirin therapy were analyzed via analysis of variance and logistic regression. RESULTS In total, 109 AERD patients underwent ESS with subsequent AD. Ten patients (9.2%) discontinued therapy after AD, before starting ATAD. Eight patients (7.3%) discontinued therapy after starting ATAD. There were 91 patients (83.5%) with no complications throughout ATAD. Reasons for discontinuation included gastritis, upper gastrointestinal (GI) bleed, anaphylaxis, persistent sinonasal symptoms, recurrent epistaxis, asthma exacerbation, and a nummular rash. There was no significant correlation between complication rate and (1) aspirin doses (analysis of variance [ANOVA] F: 0.69; p = 0.51), (2) gender (odds ratio [OR] 0.56; 95% confidence interval [CI], 0.19 to 1.65; p = 0.30), (3) age (OR 1.04; 95% CI, 0.96 to 1.09; p = 0.06), or (4) race/ethnicity (OR 1.12; 95% CI, 0.88 to 1.44; p = 0.36). CONCLUSION AD with ATAD was associated with only a 0.92% incidence of a clinically significant GI bleed, and only a 0.92% incidence of anaphylaxis. A remaining 16 patients (14.7%) discontinued aspirin therapy due to minor clinical sequelae. These findings demonstrate that the majority of AERD patients tolerate AD with ATAD without any major complications.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is commonly classified into CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Structured histopathologic reporting has the potential to identify salient histologic markers to differentiate subtypes and provide insights into pathophysiologic mechanisms in CRS. METHODS A structured histopathology report of 13 variables was prospectively employed to analyze ethmoid sinus tissue removed during endoscopic sinus surgery for 99 patients, including 43 CRSsNP and 56 CRSwNP. These variables were compared in association with presence of nasal polyps, radiographic computed tomography scores (Lund-Mackay Score [LMS]), subjective symptoms scores (SNOT-22), duration of CRS, comorbid asthma, and atopy. RESULTS Overall inflammation did not differentiate between CRSsNP and CRSwNP (p < 0.26). Compared to CRSsNP, CRSwNP had statistically significant increase in basement membrane thickening (76.8% vs 48.8%, p < 0.004), subepithelial edema (19.6% vs 2.3%, p < 0.01), fibrosis (58.9% vs 27.9%, p < 0.002), hyperplastic/papillary changes (12.5% vs 0.0%, p < 0.016), eosinophilia (41.1% vs 18.6%, p < 0.047), and eosinophilic aggregates (30.4% vs 11.6%, p < 0.022). Higher LMS was associated with increased eosinophilia (p < 0.001), eosinophil aggregates (p < 0.000), inflammation (p < 0.023), basement membrane thickening (p < 0.037), hyperplastic/papillary changes (p < 0.040) and fibrosis (p < 0.000). SNOT-22 scores were not associated with any histologic parameters. CONCLUSION Significant histopathologic differences were evident in patients with CRSwNP and CRSsNP. No single feature reliably differentiated between the 2 subtypes, underscoring the heterogeneity of CRS and limitation of this phenotypic classification system. Eosinophilic aggregates were associated with significantly worse disease, possibly signifying a unique subtype. Further studies are needed to understand the relationship of histopathologic features to disease outcome.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is likely a biologically heterogeneous disease process. Current guidelines propose subclassification using polyp status while others propose using mucosal eosinophilia. We hypothesized that appropriate CRS subclassification would increase homogeneity of baseline symptoms, and identify characteristic symptoms of each subtype. METHODS A total of 57 CRS patients undergoing surgery prospectively completed a preoperative battery of 73 questions relating to symptoms including the 22-item Sino-Nasal Outcome Test (SNOT-22) and 29-item Patient-Reported Outcomes Measurement Information System (PROMIS-29) general quality of life (QOL) measures. Eosinophilic cationic protein (ECP) levels were determined from ethmoid, uncinate, and polyp tissue homogenates using enzyme-linked immunosorbent assay (ELISA) and normalized to total protein. Patients were classified as eosinophilic (eCRS) or non-eosinophilic (neCRS) using a 95th percentile threshold established from control tissue from 82 patients without CRS. Separate pairwise comparisons were performed on patient-reported symptoms using polyp and eosinophilic status. RESULTS Of the 57 patients, 28 had CRS with nasal polyps (CRSwNP); 27 of 57 patients had eCRS (CRSwNP, n = 21; CRS without nasal polyps [CRSsNP], n = 6). CRSwNP patients had increased need to blow nose, frequency of nasal congestion, more severe difficulty breathing through nose, more severe nasal discharge, but less cough (p < 0.05). eCRS patients had more bothersome loss of taste/smell, ear pain, sneezing, severe difficulty breathing through nose, and severe nasal congestion compared to neCRS patients (p < 0.05). CONCLUSION Subclassifying CRS with symptoms alone is difficult with neither polyp status nor eosinophilia giving a distinctive clinical symptom profile. However, certain symptoms may help otolaryngologists identify CRS subtypes, which may help guide future treatments. Further validation and evaluation of prognosis following treatment is required to evaluate appropriate means of subclassifying CRS.

Abstract
BACKGROUND Reduced nasal nitric oxide (nNO) has been shown in patients with chronic rhinosinusitis (CRS) but its clinical significance remains uncertain. The objective of this study was to measure nNO changes in patients undergoing endoscopic sinus surgery (ESS) for CRS and to explore its relationship to clinical measures of sinus mucosal health postoperatively. METHODS This was a prospective study of CRS patients undergoing ESS. Patients had the following measurements at baseline and at 1 and 6 months post-ESS: nNO levels, Lund-Kennedy Endoscopy Score (LKES), and 22-item Sino-Nasal Outcome Test (SNOT-22) score. Statistical analysis was performed using GraphPad Prism 6. RESULTS Thirty-nine patients were enrolled, of these 84.6% had CRS with nasal polyps. Baseline Lund-Mackay computed tomography (CT) score was 16.9 ± 5.1. There was a statistically significant increase in nNO levels from baseline to 1 month and 6 months postoperatively (p < 0.0001). The SNOT-22 and LKES followed a similar trend with a significant and sustained improvement at 1 month and 6 months post-ESS (p < 0.0001). Subgroup analysis revealed that changes in nNO were driven by the polyp cohort because nonpolyp patients had no significant changes in their nNO postoperatively. No correlation was found between nNO levels and SNOT-22. However, a significant negative correlation was found between nNO and LKES (p < 0.0001), suggesting healthier sinus mucosa was associated with higher nNO levels. CONCLUSION This is the first study to show that nNO levels may be a marker of sinus mucosal health following ESS in patients with polyps. This has important implications for nNO in its potential etiologic role in mediating ongoing sinus inflammation.
