Abstract
Treatable traits is a personalized medicine approach to the management of airway disease. Assessing traits within the 3 domains of pulmonary, extrapulmonary, and behavioral/lifestyle/risk factor traits, and applying targeted treatments to effectively manage these traits, enables a holistic and personalized approach to care. Asthma is a heterogeneous and complex airway disease that is frequently complicated by several extrapulmonary traits that impact asthma outcomes and predict future outcomes. We propose that the identification of extrapulmonary and behavioral risk factor traits and the implementation of targeted therapy will lead to improved management of people with asthma. Furthermore, many extrapulmonary traits present as "connected comorbidities"; that is, they coexist with asthma, have an impact on asthma, and effective treatment improves both asthma and the comorbidity or the comorbidities may share a similar mechanism. In this review, we explore this concept and look at atopic dermatitis, chronic rhinosinusitis with nasal polyps, gastroesophageal reflux disease, anxiety, and depression as treatable traits of asthma and how these can be managed using this approach.

Abstract
Background Central compartment atopic disease (CCAD) is a subtype of chronic rhinosinusitis (CRS). Research focusing on the endoscopic sinus surgery (ESS) outcomes of CCAD is limited. This study aimed to evaluate the outcomes of ESS in CCAD and compared to 2 following subtypes: chronic rhinosinusitis with nasal polyps (CRSwNP) and concomitant polypoid disease in the central compartment (CRSwNP/CC) and CRSwNP not otherwise specified (CRSwNP NOS). Methods This case-control study enrolled patients with bilateral CRSwNP who underwent ESS and had at least 1 year of follow-up. Patients were classified into CCAD, CRSwNP/CC, and CRSwNP NOS. The demographic data, preoperative disease severity, and surgery outcomes, including CRS control status, endoscopic score, and symptom scores at 1 year postoperatively, were collected. We defined well controlled and partly controlled as appropriate disease control. Results This study screened 259 patients and enrolled 138 patients with complete medical records and 1-year follow-up (CCAD N = 51, CRSwNP/CC N = 55, CRSwNP NOS N = 32). Among them, appropriate disease control was achieved in 84.3% of patients (43/51) in the CCAD group, 69.1% (38/55) in the CRSwNP/CC group, and 93.7% (30/32) in the CRSwNP NOS group (P = 0.029). Then we performed post-hoc analysis using appropriate disease control and uncontrolled. There was a significant difference between CRSwNP/CC and CRSwNP NOS (P = 0.007), but no significant difference compared CCAD group to CRSwNP/CC group (P = 0.065) and CRSwNP NOS group (P = 0.199). There were significant differences in endoscopic E-score among groups (P < 0.001). In post-hoc analysis, we found that CRSwNP/CC (Median [IQR], 33.32 [42.14]) had a significantly worse E-score than CCAD (8.33 [16.67]) and CRSwNP NOS (4.17 [8.30]). Also, postoperative olfactory visual analog scale (VAS) scores significantly differed among groups (P = 0.043). However, post-hoc analysis showed no difference between any 2 groups. There were no differences in postoperative VAS scores of obstruction (P = 0.159), rhinorrhea (P = 0.398), and headache/facial pain (P = 0.092). Conclusion Most CCAD patients had good surgical outcomes 1 year after surgery. Meanwhile, the CRSwNP/CC group had the fewest patients under appropriate disease control.

Int Forum Allergy Rhinol 2023; 13:2144-2155. [PMID: 37264735 DOI: 10.1002/alr.23202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 05/17/2023] [Accepted: 05/29/2023] [Indexed: 06/03/2023]
Abstract
BACKGROUND Eosinophils are associated with olfactory dysfunction in chronic rhinosinusitis (CRS) and eosinophil-derived neurotoxin (EDN) is a sensitive marker of intense eosinophil activation. This study aimed to analyze olfactory cleft mucus and olfactory mucosa EDN levels and their association with olfactory dysfunction in CRS. METHODS We prospectively recruited 150 patients with CRS electing endoscopic sinus surgery and 25 healthy controls. Both superior turbinate biopsy specimens and olfactory cleft mucus were collected to analyze EDN levels. Sniffin' Sticks test scores, olfactory cleft computed tomography (CT) scores, and olfactory cleft endoscopy scale (OCES) were obtained. Multivariable logistic regression analysis was applied to analyze the predictability of EDN levels for olfactory dysfunction in CRS. RESULTS Chronic rhinosinusitis with olfactory dysfunction presented significantly higher olfactory mucosa (p = 0.016) and olfactory cleft mucus (p < 0.001) EDN levels than CRS without olfactory dysfunction. Mucus EDN levels were positively correlated with blood eosinophils (r = 0.625, p = 0.002), olfactory cleft CT scores (r = 0.738, p < 0.001), and OCES (r = 0.605, p = 0.004) in CRS. Furthermore, mucus EDN levels were significantly negatively correlated with threshold, discrimination, and identification (TDI) (r = -0.688), olfactory threshold (r = -0.606), olfactory discrimination (r = -0.608), and olfactory identification (r = -0.697) scores. After adjusting for patient demographics and comorbidities, mucus EDN levels were significantly associated with olfactory dysfunction in CRS (odds ratio = 2.162; p = 0.027). Mucus EDN levels showed a significantly better performance for predicting olfactory dysfunction than blood eosinophil counts (area under the curve, 0.873 vs. 0.764, p = 0.024). CONCLUSION Olfactory cleft mucus EDN level may be a better biomarker for predicting olfactory dysfunction in CRS than blood eosinophil counts.

Abstract
OBJECTIVES To investigate the value of secretions Eosinophilic cationic protein (ECP) detection in the diagnosis of endotypes of Chronic rhinosinusitis (CRS) and its correlation with clinical symptoms, so as to provide guidance for the clinical application of EOS and ECP detection in secretions. METHODS Patients' nasal secretions and polyps (or middle turbinate for control) were collected and their EOS% and ECP levels were measured. Correlation analysis was performed for EOS% and ECP levels in secretions and tissues, respectively. The correlation between secretions EOS% and ECP and clinical symptom scores (symptomatic visual analog scale (VAS) scores, Lanza-kennedy scores from nasal endoscopy and Lund-Mackay scores from sinus CT) was further analyzed. Receiver operating characteristic curves were used to assess the predictive potential of EOS% and ECP in nasal secretions. RESULTS Eosinophilic chronic rhinosinusitis (ECRS) patients had higher concentrations of ECP in nasal secretions than healthy subjects and NECRS (non-eosinophilic CRS) (p < 0.0001;0.0001); EOS% in nasal secretions was higher in ECRS than healthy subjects (p = 0.0055), but the differences between ECRS and NECRS were not statistically significant (p = 0.0999). Correlation analysis showed that tissue EOS% was correlated with ECP concentration and EOS% in nasal secretions (R = 0.5943;0.2815). There was a correlation between EOS% in secretions with a total LM score (R = 0.3131); ECP concentration in secretions with a total LK score (R = 0.3792). To diagnose ECRS, the highest area under the curve (0.8230) was determined for ECP in secretions; the highest area under the curve (0.6635) was determined for EOS% in secretions. CONCLUSION Measurement of ECP in nasal secretions is useful for non-invasive diagnosis of ECRS. LEVEL OF EVIDENCE 3 Laryngoscope, 133:3304-3312, 2023.

Abstract
Objective:To investigate whether changes in postoperative symptoms and signs in patients can predict the recurrence of ECRS after nasal endoscopic sinus surgery. Methods:A total of 70 adult patients with ECRS were enrolled for ESS surgery from June 2020 to March 2022 in a single center. There were 50 males and 20 females, with an average age of (46.9±14.5) years. Follow-up after ESS was at least 52 weeks. Patients undergo peripheral blood tests, CT of the sinuses, olfactory T&T test, visual analogue scale of symptoms(VAS), and endoscopic scoring. Results:VAS scores and endoscopic scores were analyzed at preoperative and 6th week, 12th week, 24th week and 52th week postoperative. After 12th week postoperatively, there was a clear correlation between symptom scores and endoscopic scores. Moreover, olfactory disorder and nasal discharge were the two most obvious symptoms. There were differences in the expression of multiple preoperative clinical inflammatory indicators between the symptom-controled group and the symptom-uncontrolled group(previous surgical history, concomitant asthma, nasal smear eosinophil, serum EOS%, total IgE, CT score, olfactory score, and symptom score, all with P<0.05), while there was no difference in baseline endoscopic score(P>0.05). At 12th week postoperative, the two groups of patients showed significant differences in both symptom scores and endoscopic scores. The symptoms and endoscopic score at the 12th week point of follow-up were used as predictive indicators for recurrence, with sensitivity and specificity of 62.5% and 83.3%, respectively. Conclusion:The changes in postoperative symptom score and endoscopic score in ECRSwNP patients indicated that the recurred ECRS. In the symptom-uncontrolled group, symptomatic and endoscopic scores showed consistent increased scores; In the symptom-controlled group, conflicting results between increased endoscopic scores and stable symptoms suggest that the presence of asymptomatic recurrence must be considered. The changes in symptoms and signs at the 12th week point of follow-up can serve as clinical indicators for preventing disease recurrence.

Abstract
OBJECTIVE This study aimed to explore the utility of the eosinophil percentage in peripheral blood for guiding post-operative glucocorticoid therapy in patients with chronic rhinosinusitis with nasal polyps. METHODS Forty-four patients with chronic rhinosinusitis with nasal polyps underwent functional endoscopic sinus surgery and were randomly divided into two groups. Patients in the standard treatment group used oral and nasal spray glucocorticoids. In the biomarker treatment group, patients with peripheral blood eosinophil percentage values less than 3.05 per cent did not receive glucocorticoid treatment, whereas patients with values 3.05 per cent or above were part of the standard treatment group. Visual Analogue Scale, Sino-Nasal Outcome Test-22 scores, endoscopic Lund-Kennedy scores, eosinophils, interleukin-5 and eosinophil cationic protein in peripheral blood, and nasal secretions were measured. RESULTS After functional endoscopic sinus surgery, the Visual Analogue Scale, Sino-Nasal Outcome Test-22 and Lund-Kennedy scores were significantly reduced in both groups; there were no significant differences in those indicators between the groups during the three follow-up visits. CONCLUSION Peripheral blood eosinophil percentage offers a potential biomarker to guide post-operative glucocorticoid therapy in patients with chronic rhinosinusitis with nasal polyps.

Abstract
OBJECTIVE To perform a systematic review of proposed sinus computed tomography (CT) scoring systems and determine their association with patient-reported outcome measures (PROMs). DATA SOURCES PubMed, CINAHL, Scopus, and Cochrane Library. REVIEW METHODS A systematic search was conducted following the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses) for studies describing CT scores and PROMs in patients with chronic rhinosinusitis. RESULTS A total of 144 studies were included. Out of 20,741 patients, 53.6% were male and 55.5% had nasal polyposis. A meta-analysis of correlations revealed a moderate correlation between Lund-McKay (LM) and the 22-item Sinonasal Outcome Test (SNOT-22; r = 0.434, P < .001) and a weaker correlation between LM and the 20-item Sinonasal Outcome Test (SNOT-20; r = 0.257, P = .039). Meta-regression also revealed a weak association between LM and SNOT-20 (n = 25 studies) but no significant associations between Zinreich score and SNOT-22 or LM scores and PROMs, including SNOT-22 (n = 94 studies), Rhinosinusitis Disability Index (n = 25), nasal obstruction visual analog scale (n = 15), Chronic Sinusitis Survey (n = 12), Total Nasal Symptom Score (n = 4), Total Symptom Score (n = 3), and 12-Item Short Form Health Survey (n = 3). CONCLUSION There is essentially little association between radiologic grade and PROMs. CT grading systems with improved clinical utility are needed.

Abstract
PURPOSE To evaluate the putative association between subjective symptoms and eosinophilic inflammation in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS A total of 102 patients with CRSwNP who underwent endoscopic sinus surgery were prospectively enrolled. The Sinonasal Outcomes Test-22 scores (SNOT-22), EuroQol 5-dimensional Questionnaire scores (ED-5D), and Lund-Mackay scores by computed tomography (CT) were obtained. Patients were grouped as eosinophilic CRSwNP (eCRSwNP) and non-eosinophilic CRSwNP (neCRSwNP). ECRSwNP was defined if tissue eosinophils of nasal polyps were greater than or equal to 8/HPF according to positive major basic protein (MBP) staining, and neCRSwNP otherwise. RESULTS Thirty neCRSwNP and 72 eCRSwNP patients were included. ECRSwNP patients had higher incidences of asthma (p = 0.001), allergic rhinitis (p = 0.001), and ethmoid-to-maxillary opacification ratio on CT scans (p < 0.001), whereas the proportion of purulent discharge (p < 0.001) and maxillary sinus score (p = 0.002) was higher in the neCRSwNP patients. There were no significant differences between patients on the mains of the EQ-5D health utility values and total SNOT-22 score. However, eCRSwNP patients had higher SNOT-22 scores of sneezing (p = 0.006), runny nose (p < 0.001), and ear/facial domain (p = 0.012), and lower scores of thick nasal discharge (p = 0.015) and blockage (p = 0.042). Sneezing, thick nasal discharge, and blockage/congestion of nose were recognized as independent factors of CRSwNP. CONCLUSION Sneezing was an independent predictor of eCRSwNP, and thick nasal discharge and blockage/congestion of nose were independent predictors of neCRSwNP.

Abstract
(1) Background: Factors influencing the quality of life (QoL) of patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) are poorly understood. We set out to determine the predictive factors on patients' QoL using the Sino-Nasal Outcome Test-22 (SNOT-22); (2) Methods: An ambispective analysis of data from patients diagnosed with CRSwNP in our institution. All the patients underwent a nasal polyp biopsy and completed the SNOT-22 questionnaire. Demographic and molecular data as well as the SNOT-22 scores were collected. Patients were classified in six subgroups considering the presence of asthma, non-steroidal drugs (NSAID) intolerance and corticosteroid resistance; (3) Results: The mean SNOT-22 score was 39. Considering the clinical parameters, the SNOT-22 value was significantly associated with NSAID intolerance (p = 0.04) and the endoscopic polyp score (p = 0.04). A high SNOT-22 value was also correlated with high tissue eosinophilia (p = 0.01) and high IL-8 expression; (4) Conclusions: Eosinophilia, IL-8 expression and NSAID intolerance can be used as predictors of worse QoL in patients with CRSwNP.

Abstract
The COVID-19 pandemic has raised awareness about olfactory dysfunction, although a loss of smell was present in the general population before COVID-19. Chronic rhinosinusitis (CRS) is a common upper airway chronic inflammatory disease that is also one of the most common causes of olfactory dysfunction. It can be classified into different phenotypes (ie, with and without nasal polyps) and endotypes (ie, type 2 and non-type 2 inflammation). However, scientific information regarding CRS within the context of COVID-19 is still scarce. This review focuses on (1) the potential effects of severe acute respiratory syndrome coronavirus 2 infection on CRS symptoms, including a loss of smell, and comorbidities; (2) the pathophysiologic mechanisms involved in the olfactory dysfunction; (3) CRS diagnosis in the context of COVID-19, including telemedicine; (4) the protective hypothesis of CRS in COVID-19; and (5) the efficacy and safety of therapeutic options for CRS within the context of COVID-19.

Abstract
The mechanisms underlying neutrophilic inflammation in chronic rhinosinusitis with nasal polyps (CRSwNP) remain poorly investigated. This study aimed to examine the factors that contribute to tissue neutrophilia in CRSwNP. The numbers of neutrophils and active caspase-3-positive apoptotic neutrophils in sinonasal tissues were assessed via immunofluorescence staining. The 95th percentile of tissue neutrophil numbers in control subjects was selected as a cut-off to define neutrophil-high (Neu-high) or neutrophil-low (Neu-low) nasal polyps (NPs). The levels of 34 inflammatory mediators in sinonasal tissues were analyzed using Bio-Plex assay. Purified human peripheral blood neutrophils were incubated with nasal tissue homogenates, and the apoptotic neutrophils were assessed via flow cytometry. The cut-off for Neu-high NPs was >10 myeloperoxidase positive cells/high-power field. Compared with Neu-low NPs, Neu-high NPs had higher tissue levels of IL-1β, IL-1Ra, IL-6, IL-8, G-CSF, MCP-1, and MIP-1α, but lower levels of IL-5, IL-13, IgE, and eosinophils. Principal component and multiple correspondence analyses revealed mixed type 1, type 2, and type 3 endotypes for Neu-low NPs, and predominant type 1 and type 3 endotypes for Neu-high NPs. Neu-high NPs had lower percentages of apoptotic neutrophils than Neu-low NPs. The numbers of neutrophils and the percentages of apoptotic neutrophils correlated with G-CSF and IL-6 levels in the NPs. Tissue homogenates from Neu-high NPs, but not those from Neu-low NPs, suppressed neutrophil apoptosis in vitro, which was reversed by anti-G-CSF treatment. Tissue neutrophil numbers were associated with difficult-to-treat disease in patients with CRSwNP after surgery. We propose that G-CSF promotes neutrophilic inflammation by inhibiting neutrophil apoptosis in CRSwNP.

Abstract
Asthma, atopic dermatitis and chronic rhinoconjunctivitis are highly heterogeneous. However, epidemiologic associations exist between phenotypic groups of patients. Atopic march is one such association but is not the only common point. Indeed, beyond such phenotypes, hallmarks of type 2 immunity have been found in these diseases involving immune dysregulation as well as environmental triggers and epithelial dysfunction. From the canonical Th2 cytokines (IL-4, IL-5, IL-13), new cellular and molecular actors arise, from the epithelium's alarmins to new innate immune cells. Their interactions are now better understood across the different environmental barriers, and slight differences appeared. In parallel, the development of type 2-targeting biotherapies not only raised hope to treat those diseases but also raised new questions regarding their true pathophysiological involvement. Here, we review the place of type 2 immunity in the different phenotypes of asthma, chronic rhinitis, chronic rhinosinusitis and atopic dermatitis, highlighting nuances between them. New hypotheses rising from the use of biotherapies will be discussed along with the uncertainties and unmet needs of this field.

Abstract
BACKGROUND Eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) is a refractory subtype of chronic rhinosinusitis with nasal polyps (CRSwNP), with clinical characteristics differing from those of non-ECRSwNP. We aimed to explore the predictive value of clinical characteristics, including medical history, symptoms, and signs, prior to ECRSwNP diagnosis, and to develop a nomogram for use in clinical practice. METHODS A total of 502 patients with CRSwNP were enrolled. Based on the degree of eosinophilic infiltration in nasal polyps (NPs), patients were classified as ECRSwNP or non-ECRSwNP group. Participants' demographic characteristics, asthma history, severity of nasal symptoms (nasal obstruction, rhinorrhea, hyposmia, and facial pain/headache) according to the visual analog scale, and nasal polyp scores based on polyp scoring system were recorded. Logistic regression analysis was performed to screen for independent risk factors, and a model nomogram was constructed. RESULTS The percentage of asthmatic patients and the hyposmia, rhinorrhea, and total nasal symptom scores were significantly higher in ECRSwNP patients than that in non-ECRSwNP patients. The nasal polyp score was lower in the eosinophilic group than that in the non-eosinophilic group. Logistic regression analysis revealed that asthma history and hyposmia, rhinorrhea and nasal polyp scores were independent predictors of ECRSwNP. A nomogram consisting of these four independent risk factors was constructed, and its C-index was 0.808 (95% CI, 0.771 to 0.846). CONCLUSIONS The nomogram based on asthma history and olfactory, rhinorrhea, and nasal polyp scores could help predict ECRSwNP, providing a simple, fast, and practical way to distinguish ECRSwNP from non-ECRSwNP cases in clinical practice.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by Th2-skewed inflammation and increased colonization by Staphylococcus aureus. CRSwNP can be distinguished as eosinophilic (ECRSwNP) and non-eosinophilic (NECRSwNP) by the infiltration of eosinophils. The local microbiota plays an important role in the persistent inflammation of CRSwNP. To evaluate the bacterial community composition on the distinct types of CRSwNP patients, we collected nasal swabs from 16 ECRSwNP patients, 18 NECRSwNP patients, and 39 healthy control subjects. The microbiome structure for all the samples were analyzed by high-throughput 16S rRNA gene sequencing. Concentration of S. aureus was determined using TaqMan quantitative polymerase chain reaction (qPCR) targeting the nuclease (nuc) gene. The result showed significant differences in the sinus microbiome among healthy control subjects and CRSwNP patients. Microbiota community diversity was significantly lower in NECRSwNP samples compared to that of healthy control subjects. Interestingly, the abundance of several pathogenic bacteria was diverse between ECRSwNP and NECRSwNP patients. Although Staphylococcus prevailed in all groups, the abundance of Staphylococcus was significantly higher in the healthy control group than the ECRSwNP group. More importantly, the abundance of S. aureus was much higher in NECRSwNP patients. This study highlights that microbiota composition may contribute to the different clinical types of CRSwNP, inspiring new therapeutic strategies to resolve this chronic inflammation process.

Mepolizumab decreased the levels of serum galectin-10 and eosinophil cationic protein in asthma. Asia Pac Allergy 2021; 11:e31. [PMID: 34386407 PMCID: PMC8331256 DOI: 10.5415/apallergy.2021.11.e31] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 07/10/2021] [Indexed: 12/28/2022] Open
Abstract
Background Mepolizumab, a humanized antibody targeting interleukin-5, decreases the number of blood eosinophils and the frequency of exacerbation of severe asthma. Galectin-10 is a protein within the cytoplasm of eosinophils and constitutes Charcot-Leyden crystals, which promotes key features of asthma. However, the relationship between time kinetics and clinical response of eosinophil-derived molecules such as galectin-10 or eosinophil cationic protein (ECP) has not been precisely investigated. Objective This study aimed to clarify the precise time course of the levels of serum galectin-10 and ECP after mepolizumab treatment and to analyze the relationship between the levels of eosinophil-derived molecules and the clinical background or response to mepolizumab treatment. Methods This multicenter, prospective open-label study recruited 20 patients with severe eosinophilic asthma. Mepolizumab was administered every 4 weeks for 32 weeks and the levels of various biomarkers were serially analyzed. Results The serum galectin-10 and ECP significantly and rapidly decreased 4 weeks after initial administration of mepolizumab. In contrast, basophil count, fractional exhaled nitric oxide, and the serum total IgE level were unchanged during treatment. Asthma Control Questionnaire-5, Asthma Health Questionnaire-33, and Lund-Mackay scores significantly improved after mepolizumab treatment. Both high ECP and eosinophil count related to better response in forced expiratory volume in 1 second (FEV1) and measurable ECP level at 4 weeks after administration of mepolizumab related to the further improvement in FEV1 toward week 32. No significant difference in improvement in FEV1 was observed in galectin-10 high group. The level of ECP at baseline was significantly related to the higher prevalence of nasal polyp and Lund-Mackay score. Conclusion This study was the first to show that the levels of serum galectin-10 decreases after initial administration of mepolizumab. The significant relationship between serum ECP and better response in FEV1 suggested the potential role of serum ECP as a predictive biomarker for the efficacy of mepolizumab (UMIN000030466).

Indirect Treatment Comparison of Biologics in Chronic Rhinosinusitis with Nasal Polyps. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:2461-2471.e5. [PMID: 33548517 DOI: 10.1016/j.jaip.2021.01.031] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 12/09/2020] [Accepted: 01/22/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Among patients with chronic rhinosinusitis with nasal polyps (CRSwNP), randomized clinical trials (RCTs) of biologics, such as anti-interleukin-4/interleukin-13 (dupilumab) and anti-immunoglobulin E (omalizumab), have demonstrated efficacy compared with intranasal corticosteroids (INCS). However, no head-to-head RCTs exist between biologics. OBJECTIVE To perform an indirect treatment comparison (ITC) of the efficacy of biologics plus INCS versus placebo (INCS) as a common comparator. METHODS Embase, MEDLINE, and Cochrane were searched for RCTs of biologics in CRSwNP. Bucher ITCs were performed for outcomes at week 24: nasal polyp score (NPS) (range, 0-8), nasal congestion (NC) (range, 0-3), loss of smell (range, 0-3), University of Pennsylvania Smell Identification Test (range, 0-40), total symptom score (range, 0-12), 22-item sinonasal outcome test (range, 0-110), and responder analyses based on NPS or NC improvement of 1 point or greater. RESULTS Assessment of trial design, baseline characteristics, and outcome measures suggested that ITC was feasible with four phase 3 RCTs: dupilumab SINUS-24 and SINUS-52 (NCT02912468/NCT02898454) and omalizumab POLYP 1 and POLYP 2 (NCT03280550/NCT03280537). In the intent-to-treat population, dupilumab had significantly greater improvements from baseline to week 24 versus omalizumab across key outcomes: NPS (least squares mean difference [95% confidence interval], -1.04 [-1.63 to -0.44]), NC (-0.35 [-0.60 to -0.11]), loss of smell (-0.66 [-0.90 to -0.42]), University of Pennsylvania Smell Identification Test (6.70 [4.67-8.73]), and total symptom score (-1.18 [-1.95 to -0.41]). Improvement in the 22-item sinonasal outcome test was greater in dupilumab versus omalizumab but was not statistically significant. Dupilumab patients were significantly more likely to achieve ≥1-point improvement in NPS (odds ratio [95% CI] = 3.58 [1.82-7.04]) and NC (2.13 [1.12-4.04]) versus omalizumab. CONCLUSIONS Although ITCs have limitations, these results demonstrated that dupilumab had consistently greater improvements in key CRSwNP outcomes versus omalizumab at week 24.

Abstract
INTRODUCTION Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the categories of chronic rhinosinusitis and is defined by the presence of bilateral polyps. It is frequently associated with other conditions (asthma, atopy, aspirin intolerance), which worsen its prognosis. STATE OF ART The pathophysiology of CRSwNP is still poorly understood. The genesis of polyps is thought to be based on an initial epithelial lesion caused by environmental factors in the context of self-maintained chronic local inflammation. Multiple local and general factors can be involved in this inflammation, which is mainly of Th2 type in Europe. Abnormalities of the epithelial barrier and the immune system (eosinophilia, cytokines, T and B lymphocytes), genetic factors and pathogens, including Staphylococcus aureus, have been incriminated. The treatment of CRSwNP is mainly based on the application of local corticosteroids. Surgery remains an important part of patient management where CRSwNP becomes resistant to topical therapy. The management of CRSwNP may be at a turning point thanks to the arrival of biological therapies (anti-IgE, anti-IL-5, anti-IL-4/IL-13) the initial results of which are promising. PERSPECTIVES/CONCLUSIONS With the new concept of endotypes, current avenues of research are moving towards a better understanding of the inflammatory mechanisms of CRSwNP. Immunotherapy appears to be a promising future for the treatment of CRSwNP.

Abstract
BACKGROUND AND OBJECTIVE Olfactory dysfunction has a high prevalence in chronic rhinosinusitis (CRS) patients and significantly affects quality of life. CRS is recognized as a complex disorder encompassing heterogeneous inflammatory processes in the nose and paranasal sinuses. Olfactory dysfunction in CRS patients is associated with the level of inflammatory mediators and the efficiency of inflammatory control. Learning about the association between CRS-related inflammation and olfactory function will provide clues to the pathogenesis of CRS. STRUCTURE The first section of this review describes the assessment of olfactory function using various measures, from ratings to MR based imaging. Then, we discuss the conductive and inflammatory mechanisms related to olfactory dysfunction in CRS: olfaction is associated with certain inflammatory patterns and is potentially a marker of CRS subtype. Finally, we review anti-inflammatory therapies including conservative and surgical approaches, and their effectiveness in olfactory dysfunction in CRS. CONCLUSION Assessment of olfactory function should be considered in the clinical evaluation of CRS patients, not only for detecting and quantifying patients' symptom, but also because it appears to be useful to objectively assess the efficacy of CRS treatment over time. In addition, olfaction can be expected to expand the library of CRS phenotypes and endotypes and, hence, pave the way for more precise, tailored treatment options.

Abstract
OBJECTIVES We conducted a systematic literature review (SLR) of randomized controlled trials and real-world evidence (RWE) studies to determine the humanistic (e.g. health-related/disease-specific quality of life [QOL]) and economic (e.g. direct and indirect costs) burdens of chronic rhinosinusitis with nasal polyposis (CRSwNP). METHODS The SLR adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Embase, MEDLINE and Evidence-Based Medicine Reviews databases were searched using OVID. Relevant studies involving adult patients with CRSwNP published between 1 January 2008 and 16 February 2019 were included, with relevant conference abstracts from 1 January 2017, onward. RESULTS Sino-Nasal Outcomes Test (SNOT)-22 was the most frequently used disease-specific health-related QOL/patient-reported outcomes instrument for patients with CRSwNP. Baseline SNOT-22 scores ranged from 25 to 73 for surgical candidates and from 14 to 56 for medically managed patients with CRSwNP. Mean baseline EuroQol-5 Dimensions (EQ-5D) index for patients with CRSwNP ranged from 0.81 to 0.86, and mean baseline Short Form-6 Dimensions (SF-6D) ranged from 0.67 to 0.75. Three months (EQ-5D) and 5 years (SF-6D) post-endoscopic sinus surgery (ESS), rates increased from 0.81 to 0.89 and from 0.69 to 0.80, respectively. One year post-diagnosis, patients with CRSwNP had significantly more systemic prescriptions, underwent significantly more medical procedures, demonstrated greater health care resource utilization and had significantly greater mean health care costs compared with matched controls (all p < .001). Overall, for patients with initial ESS, CRSwNP was associated with higher disease-related expenditures compared with CRS without nasal polyposis (NP), even for patients who did not undergo revision surgery. CONCLUSIONS This SLR identified substantial humanistic burden among surgery candidates. RWE shows that surgeries were used to treat relatively more severe CRSwNP patients as recommended by guidelines. Patient QOL is improved significantly after surgery; however, there is a lack of evidence on patients with revision surgery. Surgery is also associated with higher costs, and the presence of NP was a predictor of revision surgery. Patients with CRSwNP demonstrate greater health care resource utilization and costs compared to those with CRS without NP. Costs associated with different severity of CRSwNP and revision surgery need to be assessed further.

Abstract
INTRODUCTION Previous studies have reported a diverse range of threshold values for blood eosinophilia. In addition, a single predictive biomarker for eosinophilic chronic rhinosinusitis (CRS) with nasal polyps (ECRSwNP) has not yet been identified. OBJECTIVES The aim of this study is to compare the clinical characteristics of ECRSwNP and non-ECRSwNP to evaluate the preoperative risk of tissue eosinophilia of chronic rhinosinusitis with nasal polyps (CRSwNP) through a multiparametric statistical analysis. METHODS One hundred ten patients with evidence of chronic polypoid rhinosinusitis were included in this study and clinical records were retrospectively reviewed. Eosinophilic CRSwNP was diagnosed based on the presence of at least 10 eosinophils per high-power field. The demographic and clinical features of ECRSwNP and non-ECRSwNP are described. The values of blood eosinophilia as predictors of tissue eosinophilia have been identified using receiver operating characteristic curves. As the predictive value of the identified cutoff through regression analysis was low, we evaluated whether other risk factors could be statistically associated with ECRSwNP, and from this, a new predictive model was proposed for the identification of eosinophilic nasal polyps before surgery. RESULTS We found that the best method for predicting ECRSwNP is based on a model having asthma, blood eosinophil percentage, posterior ethmoid value in Lund-Mackay score, and modified Lund-Kennedy score as explanatory variables. CONCLUSIONS This study provides new data for a better understanding of the polypoid CRS endotypes, and the proposed model allows the endotype to be identified preoperatively.

Abstract
OBJECTIVE Most patients with chronic rhinosinusitis (CRS) complain of olfactory and/or taste dysfunctions. However, olfactory and taste dysfunctions depending on the subtype of CRS, classified as eosinophilic CRS (ECRS) and non-eosinophilic CRS (NCRS), have not been clearly reported. Therefore, the purpose of this study was to investigate the clinical features in olfactory and taste functions according to the subtype classified as ECRS and NCRS. METHODS We retrospectively analyzed the electronic medical records of patients who underwent endoscopic sinus surgery and were diagnosed with CRS. The patients were divided into ECRS and NCRS groups, according to their Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis (JESREC) scores. We analyzed demographic characteristics, Sino-Nasal Outcome Test findings, Lund-Mackay score, and the results of previously-validated tests, including the Korean Version of Sniffin' Stick test and chemical gustatory function test. RESULTS Patients with ECRS and NCRS had decreased olfactory and taste functions compared to the control group. In particular, the olfactory score of ECRS patients was lower than that of NCRS patients (18.1 ± 9.5 vs 23.7 ± 8.5, respectively, p <0.001). On the other hand, taste scores of ECRS patients were not statistically different compared to NCRS patients (19.1 ± 4.7 vs. 18.3 ± 4.7, respectively, p = 0.166). Olfactory score decreased with increase in JESREC score (r=-0.203, p = 0.002), but it had no correlation with taste score (r = 0.072, p = 0.276). CONCLUSION We found a difference in olfactory function but no difference in taste function between patients in ECRS and NCRS groups. These results may provide valuable clinical features in terms of olfactory and taste functions according to the subtypes of CRS.

Abstract
OBJECTIVE Eosinophilic chronic rhinosinusitis (ECRS) is a histological subtype of CRS that is generally recognised as being more difficult to manage. Patients with ECRS tend to have greater disease severity and poorer treatment outcomes after sinus surgery when compared with non-ECRS patients. The histopathology and biomarker assessments of ECRS are often unavailable prior to surgery and may be impractical and costly to analyse. Thus, the primary objective of this study was to understand clinical comorbidities associated with ECRS. DESIGN/SETTING We searched three independent databases for articles that reported clinical CRS comorbidities associated with tissue eosinophilia. Data from studies with the same reported comorbidities were pooled, and a forest plot analysis was used to assess potential associations with four different conditions including allergic rhinitis, ASA sensitivity, asthma and atopy. The association between the phenotype of nasal polyps and ECRS was also quantified as a secondary objective. ECRS cut-off levels were as defined by papers included. MAIN OUTCOME/RESULTS Eighteen articles were identified. The presence of nasal polyps (the first numbers in brackets represent odds ratios) (5.85, 95% CI [3.61, 9.49], P < .00001), ASA sensitivity (5.63, 95% CI [3.43, 9.23], P < .00001), allergic rhinitis (1.84, 95% CI [1.27, 2.67], P = .001) and asthma (3.15, 95% CI [2.61, 3.82], P < .00001) were found to be significantly associated with tissue eosinophilia. Atopy, however, was not significantly associated with tissue eosinophilia (1.71, 95% CI [0.59, 4.95], P = .32). CONCLUSION Certain clinical disease characteristics such as ASA sensitivity, allergic rhinitis and asthma are more associated with CRS patients with eosinophilia when compared to those without eosinophilia. The phenotype of nasal polyps was also associated with ECRS. It is important for surgeons to recognise these comorbidities to ensure correct diagnoses, management and follow-up are implemented.

Abstract
Eosinophilic chronic rhinosinusitis (ECRS) is a subtype of chronic rhinosinusitis (CRS) that is characterized by intractable nasal polyp formation. Eosinophil-derived neurotoxin (EDN) is an eosinophil granule protein that is closely related to allergic inflammation, but the pathological implications of EDN in ECRS remain unknown. In this study, we evaluated the function of EDN in ECRS pathogenesis and assessed its potential as a disease activity marker. Serum EDN levels were significantly higher in patients with ECRS than in those with other nasal and paranasal diseases, and were positively correlated with clinical disease activity. Production of EDN from isolated human eosinophils was induced by stimulation with IL-5 in vitro. Human nasal epithelial cells were stimulated with EDN, and the resultant changes in gene expression were detected by RNA sequencing. Pathway analysis revealed that the major canonical pathway affected by EDN stimulation was 'regulation of the epithelial-mesenchymal transition pathway'; the only gene in this pathway to be up-regulated was matrix metalloproteinase 9 (MMP-9). Consistent with this, immunostaining analysis revealed intense staining of both EDN and MMP-9 in nasal polyps from patients with ECRS. In conclusion, our data demonstrate that serum EDN level is a useful marker for the evaluation of ECRS severity. Furthermore, EDN induces production of MMP-9 from the nasal epithelium, which may be involved in the pathogenesis of ECRS.

Abstract
BACKGROUND PROMIS® items have not been widely or systematically used within the Veterans Health Administration (VA). OBJECTIVE To examine the concordance of PROMIS-29® scores and medical record diagnosis in US Veterans and to compare Veteran scores relative to US population norms. DESIGN/PARTICIPANTS Cross-sectional multi-site survey of Veterans (n = 3221) provided sociodemographic and PROMIS-29® domain data. Electronic medical records provided health condition (depression, anxiety, sleep disorders, pain disorders) diagnosis data. MAIN MEASURES For each domain, we calculated PROMIS® standardized T scores and used t tests to compare PROMIS® scores for Veterans diagnosed with each targeted health condition vs. those without that documented clinical diagnosis and compare mean Veterans' PROMIS-29® with US adult population norms. KEY RESULTS Veterans with (vs. without) a depression diagnosis reported significantly higher PROMIS® depression scores (60.3 vs. 49.6, p < .0001); those with an anxiety diagnosis (vs. without) reported higher average PROMIS® anxiety scores (62.7 vs. 50.9, p < .0001). Veterans with (vs. without) a pain disorder reported higher pain interference (65.3 vs. 57.7, p < .0001) and pain intensity (6.4 vs. 4.4, p < .0001). Veterans with (vs. without) a sleep disorder reported higher sleep disturbance (55.8 vs. 51.2, p < .0001) and fatigue (57.5 vs. 51.8, p < .0001) PROMIS® scores. Compared with the general population norms, Veterans scored worse across all PROMIS-29® domains. CONCLUSIONS We found that PROMIS-29® domains are selectively sensitive to expected differences between clinically-defined groups, suggesting their appropriateness as indicators of condition symptomology among Veterans. Notably, Veterans scored worse across all PROMIS-29(R) domains compared with population norms. Taken collectively, our findings suggest that PROMIS-29® may be a useful tool for VA providers to assess patient's physical and mental health, and because PROMIS® items are normed to the general population, this offers a way to compare the health of Veterans with the adult population at large and identify disparate areas for intervention.

Associations Between Inflammatory Endotypes and Clinical Presentations in Chronic Rhinosinusitis. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2019; 7:2812-2820.e3. [PMID: 31128376 DOI: 10.1016/j.jaip.2019.05.009] [Citation(s) in RCA: 202] [Impact Index Per Article: 40.4] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 05/07/2019] [Accepted: 05/09/2019] [Indexed: 12/22/2022]
Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by mucosal inflammation in the nose and paranasal sinuses. Inflammation in CRS is also heterogeneous and is mainly characterized by type 2 (T2) inflammation, but subsets of patients show type 1 (T1) and type 3 (T3) inflammation. Whether inflammatory endotypes are associated with clinical phenotypes has yet to be explored in detail. OBJECTIVE To identify associations between inflammatory endotypes and clinical presentations in CRS. METHODS We compared 121 patients with nonpolypoid CRS (CRSsNP) and 134 patients with polypoid CRS (CRSwNP) and identified inflammatory endotypes using markers including IFN-γ (T1), eosinophil cationic protein (T2), Charcot-Leyden crystal galectin (T2), and IL-17A (T3). We collected clinical parameters from medical and surgical records and examined whether there were any associations between endotype and clinical features. RESULTS The presence of nasal polyps, asthma comorbidity, smell loss, and allergic mucin was significantly associated with the presence of T2 endotype in all patients with CRS. The T1 endotype was significantly more common in females, and the presence of pus was significantly associated with T3 endotype in all patients with CRS. We further analyzed these associations in CRSsNP and CRSwNP separately and found that smell loss was still associated with T2 endotype and pus with the T3 endotype in both CRSsNP and CRSwNP. Importantly, patients with CRS with T2 and T3 mixed endotype tended to have clinical presentations shared by both T2 and T3 endotypes. CONCLUSIONS Clinical presentations are directly associated with inflammatory endotypes in CRS. Identification of inflammatory endotypes may allow for more precise and personalized medical treatments in CRS.

Abstract
BACKGROUND Olfactory dysfunction is frequently experienced by patients with allergic rhinitis. It is thought to result from structural and functional changes occurring in the olfactory mucosa caused by inflammation. However, the current understanding of the pathophysiology of olfactory dysfunction in allergic rhinitis remains unclear. OBJECTIVE To investigate the mechanism by which the olfactory neural cells are damaged in allergic rhinitis. METHODS Olfactory sphere cells (OSCs) were established after dissociation and serial cultures of cells from the mouse olfactory mucosa. Viability and proliferation of OSCs were compared between control and allergic rhinitis mice models, and olfactory stem cell markers were analysed in vivo. To elucidate which cytokines have an inhibitory effect on OSCs, viability and apoptotic markers of OSCs were investigated. RESULTS Olfactory sphere cells were successfully isolated from the olfactory mucosa of mice, and these cells expressed markers of neural stem cells. To investigate the neural differentiation, we performed the immunocytochemical staining and found significantly elevated expressions of Tuji1, GFAP and O4 on OSCs. On the comparison of the characteristics of OSCs between control and allergic rhinitis model, we detected significantly fewer neurospheres, reduced clonogenic capacity and decreased expression of olfactory neural stem cell markers in allergic rhinitis model. When OSCs were treated with several major allergic cytokines were treated on OSCs, only TNF-α showed an inhibitory effect on OSCs. Interestingly, IL-5 had an inhibitory effect on the viability of OSCs in combination with TNF-α, whereas IL-5 alone does not have an effect. Moreover, TNF-α combined with IL-5 significantly increased the apoptotic expression, compared with TNF-α or IL-5 alone. Additionally, allergic rhinitis mice models showed the increased apoptotic expression. CONCLUSION AND CLINICAL RELEVANCE Allergic rhinitis mice models showed lower expression of OSCs, and TNF-α combined with IL-5 had an apoptotic effect on OSCs. Therefore, these cytokines may be therapeutic targets for olfactory dysfunction in patients with allergic rhinitis.

Lou H, Zhang N, Bachert C, Zhang L. Highlights of eosinophilic chronic rhinosinusitis with nasal polyps in definition, prognosis, and advancement. Int Forum Allergy Rhinol 2018; 8:1218-1225.

Abstract
Background Tissue eosinophils are characteristic of inflammation in most but not all patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and may be useful for defining subgroups and making treatment choices. However, no consistent diagnostic criteria for CRSwNP with eosinophilic inflammation have been established. Methods Related literature review was performed and current developments in the diagnosis of eosinophilic CRSwNP were summarized. Details in histopathology, definition of tissue eosinophilia, eosinophil as an indicator of disease recurrence, eosinophilic shift, and related biomarkers in CRSwNP are included in this review article. Results Mucosal eosinophilia exhibits significant geographic and ethnic differences and may increase over time. Tissue eosinophilia can be defined using a cutoff value based on reference values from healthy mucosa, but typical disease‐specific values should also be employed to increase sensitivity and specificity for clinical use. Recent developments highlight the diagnostic criteria for eosinophilic CRSwNP based on cluster analysis, which were also associated with clinical outcomes. Additionally, some promising eosinophil‐relevant biomarkers, such as eosinophilic cation protein and interleukin 5 (IL‐5), may be clinically applied as diagnostic or predictive tools for CRSwNP in the future. Conclusion Sinonasal tissue eosinophilia is present in a majority of CRSwNP patients but is currently more common in the West than in the East. Cutoff values of eosinophils as the diagnostic criteria of eosinophilic CRSwNP are subject to change with geographic and ethnic differences over time. It will be important to identify validated eosinophil‐related biomarkers in different continents/countries for future research and for the introduction of precision medicine.

Abstract
Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have a high risk of disease recurrence and revision surgery. The ability to predict a polyp recurrence in this patient population is critical in order to provide adequately tailored postoperative management. Objective We aim to explore the role of appropriate postoperative care in the prognosis of CRSwNP patients in relation to preoperative eosinophil and basophils levels. Methods This was a retrospective case series; data were collected for 102 CRSwNP patients over a period of 15 months after surgery. Baseline eosinophil and basophil levels were compared between patients with and without polyp recurrences. The analysis was then stratified based on clinical diagnosis, comorbidities (atopy, asthma, and aspirin allergy), a single versus multiple episodes of sinonasal polyp recurrences, and medication adherence. Results Of the 102 included patients, 65 (63.7%) of the patients experienced no recurrences, 26 (25.5%) experienced a single episode of recurrence, and 11 (10.8%) experienced multiple recurrences. Mean baseline eosinophil count and percentage of total white blood cells were significantly higher in the multiple recurrences group (0.70 × 109/L and 10%) compared with the no recurrences group (0.36 × 109/L and 5%). Adherence to prescribed medical therapy prior to the first episode of recurrence was significantly lower for the single exacerbations group (42.3%) than the multiple recurrences group (88.9%). Conclusions Patients with multiple recurrences of nasal polyps had significantly higher baseline eosinophil counts and significantly higher medication adherence compared to single exacerbations of nasal polyps. Single exacerbations may not reflect true failures of surgery but rather a failure of postoperative medical care. Basophil levels were inadequate to predict polyp recurrence rates.

Abstract
PURPOSE OF REVIEW Preliminary studies have suggested differences in endotypes of chronic rhinosinusitis (CRS) across ancestry/ethnic groups. Eosinophilic CRS (ECRS) is the predominant subtype for Western/European ancestry CRS patients and non-eosinophilic CRS (nECRS) for Asian patients. This review aims to re-analyze CRS endotypes across ancestry populations using one consistent criteria to existing data. RECENT FINDINGS Although tissue eosinophilia is the most commonly used criterion for ECRS, various cut-off points are suggested. Surrogate markers have been extensively studied. Sixty-six cohorts with study criteria were included with a total of 8557 patients. Raw data from 11 studies 544 patients were re-analyzed using number of tissue eosinophils. At lower cut-off values of ≥ 5 and ≥ 10 cells/HPF, most patients of Asian and Western/European ancestry were classified as ECRS without difference. In contrast, at cut-off points of ≥ 70 and ≥ 120 cells/HPF, the majority of both groups became reclassified as nECRS. After applying one consistent criteria to existing data, differences across ancestry and geographic populations in endotypes of CRS were no longer evident.

Abstract
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory disease usually characterized by chronic eosinophilia in the sinonasal mucosa, which often requires glucocorticoid (GC) therapy. However, the therapeutic response varies markedly between individuals. The objective of this study was to evaluate the diagnostic values of sinus computed tomography (CT) for GC-sensitivity in patients with CRSwNP. Methods We conducted a prospective, single-blinded study of 47 consecutive patients with CRSwNP. These patients were given a course of oral prednisone (30 mg daily for 14 days) and subsequently classified into objectively GC-sensitive and -insensitive subgroup according to the change in nasal polyp size score, or subjectively GC-sensitive and -insensitive subgroup according to the change in total nasal symptom score. The following parameters were compared between GC-sensitive and GC-insensitive subgroups: Lund-Mackay scores, olfactory cleft (OC) scores, and blood eosinophil counts and ratio (percentage of the total white blood cells). Results 25/47 (53.2%) and 29/47 (61.7%) patients were objectively and subjectively sensitive to GC therapy, respectively. The OC score and the blood eosinophil counts and ratio in GC-sensitive subgroup were significantly higher than those in GC-insensitive subgroup, defined either objectively or subjectively. Multivariate logistic regression revealed that OC score was independent risk factor for objective or subjective GC-sensitivity. The OC score exhibited comparable accuracy with the blood eosinophil ratio as predictor of objective and subjective GC-sensitivity (the OC score AUC = 0.775 and 0.829, respectively). A OC score of 3.5 could act as a reliable indicator for predicting the clinical response to GC therapy in CRSwNP. Conclusion Our prospective findings validate the potential value of sinus CT scan in predicting GC-sensitivity in CRSwNP patients.

Abstract
BACKGROUND IgD is an enigmatic antibody isotype best known when coexpressed with IgM on naive B cells. However, increased soluble IgD (sIgD) levels and increased IgD+IgM- B-cell populations have been described in the human upper respiratory mucosa. OBJECTIVE We assessed whether levels of sIgD and IgD+ B cell counts are altered in nasal tissue from patients with chronic rhinosinusitis (CRS). We further characterized IgD+ B-cell populations and explored clinical and local inflammatory factors associated with tissue sIgD levels. METHODS sIgD levels were measured by means of ELISA in nasal tissues, nasal lavage fluid, sera, and supernatants of dissociated nasal tissues. IgD+ cells were identified by using immunofluorescence and flow cytometry. Inflammatory mediator levels in tissues were assessed by using real-time PCR and multiplex immunoassays. Bacterial cultures from the middle meatus were performed. Underlying medical history and medicine use were obtained from medical records. RESULTS sIgD levels and numbers of IgD+ cells were significantly increased in uncinate tissue (UT) of patients with chronic rhinosinusitis without nasal polyps (CRSsNP) compared with that of control subjects (4-fold, P < .05). IgD+ cells were densely scattered in the periglandular regions of UT from patients with CRSsNP. We also found that IgD+CD19+CD38bright plasmablast numbers were significantly increased in tissues from patients with CRSsNP compared with control tissues (P < .05). Among numerous factors tested, IL-2 levels were increased in UT from patients with CRSsNP and were positively correlated with tissue IgD levels. Additionally, supernatants of IL-2-stimulated dissociated tissue from patients with CRSsNP had significantly increased sIgD levels compared with those in IL-2-stimulated dissociated control tissue ex vivo (P < .05). Tissue from patients with CRS with preoperative antibiotic use or those with pathogenic bacteria showed higher IgD levels compared with tissue from patients without these variables (P < .05). CONCLUSION sIgD levels and IgD+CD19+CD38bright plasmablast counts were increased in nasal tissue of patients with CRSsNP. IgD levels were associated with increased IL-2 levels and the presence of pathogenic bacteria. These findings suggest that IgD might contribute to enhancement mucosal immunity or inflammation or respond to bacterial infections in patients with CRS, especially CRSsNP.

Abstract
Chronic rhinosinusitis (CRS) is a prevalent disease that is associated with significant costs and quality of life impairments. Currently, patients are classified into subgroups based on clinical characteristics, most often the presence or absence of nasal polyps. However, despite medical and surgical treatment, many of these patients continue to have symptoms. Recent efforts have focused on gaining a more complete understanding of the inflammatory mechanisms that drive pathogenesis in CRS, and it is becoming clear that the inflammatory processes in CRS are quite complex. As our understanding of these complex phenotypes improves, it may become possible to classify patients into endotypes based on unique inflammatory patterns within the sinus mucosa. This information may also lead to the identification of appropriate targeted therapies for different endotypes. This review will discuss our current understanding of endotypes in CRS along with the unique adaptive immune responses that may contribute to these different endotypes and, finally, some potential targeted therapeutics for the next generation of CRS treatment strategies.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) has a high propensity for recurrence. Studies suggest that eosinophilia influences disease severity and surgical outcomes, but the selection of sinonasal site for measuring eosinophilia has not been examined. The aim of this study was to investigate how region-specific tissue eosinophilia affects radiographic severity, comorbidity prevalence, and polyp recurrence risk following sinus surgery. METHODS Eosinophil cationic protein (ECP) levels in uncinate tissue (UT) and nasal polyp (NP) homogenates from 116 CRSwNP patients were measured using enzyme-linked immunosorbent assay (ELISA). Clinical history, radiographic severity, and time to polyp recurrence were obtained from electronic health records. The correlations between baseline Lund-Mackay scores and comorbidities were compared between UT and NP ECP levels. Cox regression and Kaplan-Meier analysis were then performed to assess whether UT or NP ECP better predicted recurrence. Censoring occurred at 4 years or at last follow-up if there was no endoscopic diagnosis of recurrent polyps. RESULTS Lund-Mackay scores were significantly correlated with UT and NP ECP (r = 0.46 and 0.26 respectively, p < 0.05). UT but not NP ECP was significantly higher in patients with asthma (p < 0.01) and aspirin-exacerbated respiratory disease (AERD) (p < 0.05). Polyp recurrence risk was only significantly higher for patients with eosinophilic UT tissue (hazard ratio [HR] = 2.84, p = 0.025). When measured in NP, eosinophilia did not predict recurrence. CONCLUSION Although ECP in NP was higher than in UT tissue, eosinophilia in UT tissue was a more clinically coherent biomarker of baseline radiographic severity, comorbid asthma and AERD, and prospective polyp recurrence risk than NP eosinophilia.

Abstract
Chronic rhinosinusitis (CRS) can be classified according to the presence of a nasal polyp (NP): CRS with NP (CRSwNP) and CRS without NP (CRSsNP). CRSwNP has characteristics with high infiltration of tissue eosinophilia with a burst of Th2 inflammatory cytokine. However recent findings in Eastern Asia countries suggest that CRSwNP can be divided according to the presence of tissue eosinophilia. Thus, CRSwNP can be classified into eosinophilic and noneosinophilic. Eosinophilic CRSwNP seems to have different immunological and clinical feature compared to noneosinophilic CRSwNP. From the same point of view, CRSsNP can also be divided according to tissue eosinophilia. However, the meaning of this dichotomous categorization in CRS seems to be not quite clear. This review focus on the limitations in current subclassification of CRS according to the presence of NP and tissue eosinophilia and discuss other factors related to tissue remodeling and NP generation which may provide clues for the further understanding of CRS pathogenesis.

Abstract
Objective: The study aimed to evaluate symptoms described by patients with chronic rhinosinusitis with polypoid changes/nasal polyps and their correlation with computed tomography (CT), nasal endoscopy, and intranasal biomarkers. Study Design: Prospective multicenter study symptom data from postsurgical adult chronic rhinosinusitis study participants with recurrent disease refractory to medical therapy were analyzed in comparison with objective data. Methods: Using logistic regression analysis, participant-rated 16-question surveys from 258 participants were assessed for correlation with nasal endoscopy scores, CT percentage of sinus occlusion, and intranasal biomarkers of fungal antigens (Alternaria and Aspergillus), eosinophilic inflammation (eosinophil-derived neurotoxin [EDN] and major basic protein [MBP]), and inflammatory cytokines (interleukins 5 and 13). Results: Study participant assessments revealed increased CT occlusion in participants presenting with greater inability to smell ( P < .019). Mucosal inflammation identified on nasal endoscopy was positively correlated with congestion ( P < .028), runny nose ( P < .002), and ear pain ( P < .007). Elevated EDN was positively correlated in patients with bothersome congestion ( P < .031) and runny nose ( P < .011). Sneezing was positively correlated with multiple markers: Alternaria ( P < .024), interleukin-13 ( P < .027), MBP ( P < .034), and interleukin-5 ( P < .019). Conclusion: Nasal endoscopy, not CT imaging, has the strongest correlation with the 2 cardinal symptoms of congestion and runny nose in CRS patients; these correlate with biomarkers of eosinophilic inflammation.

Abstract
An estimated 4.5% of total US health care dollars have been devoted to mitigating chronic rhinosinusitis. The most recalcitrant of these patients undergo surgery, which fails to improve symptoms in approximately 25% of patients. Recent advances in informational, microbiomic, and genomic analysis have introduced the first set of tools that patients, physicians, politicians, and payers can apply to better forecast which patients will respond favorably to endoscopic sinus surgery. This article summarizes the forces driving the application of personalized medicine to CRS and how new advances can be applied to clinical practice.

Abstract
OBJECTIVES/HYPOTHESIS Eosinophilic chronic rhinosinusitis (eCRS) has recently been recognized as a CRS subtype characterized by inflammation rather than chronic infection. Consequently, the role of antibiotics as a component of maximal medical therapy for eCRS has been called into question. The purpose of this study was to investigate whether the use of antibiotics, which lack any secondary anti-inflammatory properties, are useful in the treatment of eCRS. STUDY DESIGN Prospective individual cohort study. METHODS Institutional review board-approved, prospective study of 39 patients presenting with chronic rhinosinusitis (CRS). In all patients, Lund-Kennedy endoscopy scores, Lund-Mackay computed tomography scores, and Sino-Nasal Outcome Test-22(SNOT-22) scores were obtained before and after treatment with amoxicillin-clavulanic acid twice a day (625 mg) for 4 weeks. Patients were subsequently stratified into eCRS and non-eCRS groups based on having over 10 eosinophils per high-power field by histopathological examination. The efficacy of antibiotic therapy was compared between groups using the nonparametric Mann-Whitney U test. RESULTS Within the non-eCRS group (n = 14), there was a significant improvement in both the Lund-Mackay score (P = .002) and SNOT-22 score (P < .001) but not the endoscopy score. Among the eCRS patients (n = 25), the Lund-Mackay score was similarly improved (P = .007); however, there was no significant improvement in the endoscopy or SNOT-22 scores. CONCLUSIONS The use of antibiotics without independent anti-inflammatory properties have limited efficacy in patients with eCRS. The concept of maximal medical therapy using antibiotics must continue to evolve in the setting of new evidence for inflammatory subtypes of CRS. LEVEL OF EVIDENCE 2b.

Evaluating metrics of responsiveness using patient-reported outcome measures in chronic rhinosinusitis. Int Forum Allergy Rhinol 2016; 7:128-134. [PMID: 28177596 DOI: 10.1002/alr.21866] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Revised: 09/11/2016] [Accepted: 09/22/2016] [Indexed: 11/12/2022]
Abstract
BACKGROUND Responsiveness, or sensitivity to clinical change, is important when selecting patient-reported outcome measures (PROMs) for research and clinical applications. This study compares responsiveness of PROMs used in chronic rhinosinusitis (CRS) to inform the future development of a highly responsive instrument that accurately portrays CRS patients' symptom experiences. METHODS Adult CRS patients initiating medical therapy (MT; n = 143) or undergoing endoscopic sinus surgery after failing MT (ESS; n = 123) completed the 22-item Sino-Nasal Outcome Test (SNOT-22), European Position Statement on Rhinosinusitis (EPOS) visual analog scale (VAS), and 29-item Patient-Reported Outcomes Measurement Information System (PROMIS-29) at baseline and 3 months after treatment. Cohen's d and paired t statistics were used to evaluate the responsiveness of each measure. RESULTS Fifty-two (36.4%) subjects and 42 (34.1%) subjects in the MT and ESS groups, respectively, completed baseline and 3-month questionnaires. Subjects with and without 3-month data were similar with respect to baseline demographics, VAS scores, and SNOT-22 scores (p > 0.05). In MT patients, CRS-specific measures, like VAS (d = -0.58, p < 0.01; t = -1.81, p > 0.05) and SNOT-22 (d = -0.70, p < 0.01; t = -3.29, p < 0.05) scores, were more responsive than PROMIS-29 general health domains (p > 0.05 for Cohen's d). In ESS patients, VAS (d = -1.97; t = -9.63, both p < 0.01) and SNOT-22 (d = -1.56; t = -9.99, both p < 0.01) scores were similarly more responsive, although changes in PROMIS-29 domains of Fatigue (d = -0.82, p = 0.01; t = -4.63, p < 0.01), Sleep Disturbance (d = -0.83; t = -3.77, both p < 0.01), and Pain Intensity (d = -1.0; t = -5.67, both p < 0.01) were significant. All 22 individual SNOT-22 items differed significantly after surgery, whereas only 8 items were consistently responsive after MT. CONCLUSIONS For both MT and ESS patients, CRS-specific PROMs are more responsive to posttreatment clinical changes than general health measures. Still, the SNOT-22 contains items that likely decrease its overall responsiveness. Our findings also indicate that existing PROMs had a greater response to ESS than MT.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is an important clinical entity diagnosed by the presence of both subjective and objective evidence of chronic sinonasal inflammation. Symptoms include anterior or posterior rhinorrhea, nasal congestion, hyposmia, and/or facial pressure or pain that last for a duration of more than 12 weeks. Nasal polyps are inflammatory lesions that project into the nasal airway, are typically bilateral, and originate from the ethmoid sinus. Males are more likely to be affected than females, but no specific genetic or environmental factors have been strongly linked to the development of this disorder to date. CRSwNP is frequently associated with asthma and allergic rhinitis, but the cellular and molecular mechanisms that contribute to the clinical symptoms are not fully understood. Defects in the sinonasal epithelial cell barrier, increased exposure to pathogenic and colonized bacteria, and dysregulation of the host immune system are all thought to play prominent roles in disease pathogenesis. Additional studies are needed to further explore the clinical and pathophysiological features of CRSwNP so that biomarkers can be identified and novel advances can be made to improve the treatment and management of this disease.
