Abstract
INTRODUCTION A particularly aggressive course of chronic sinusitis with nasal polyps is seen in patients with bronchial asthma and hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs). These patients often report exacerbation associated with consumption of foods reach in salicylates. Therefore, the authors analyzed the effect of a low-salicylate diet (LSD) on the course of chronic sinusitis with polyps in patients with NSAID-exacerbated respiratory disease (N-ERD) to answer the question: which patients would obtain the best therapeutic benefit? METHODS Adult patients with N-ERD were selected for dietary intervention with LSD. Patients were seen on two occasions: at an initial visit and a follow-up after 12 weeks of diet. At both visits, an evaluation was performed with total nasal symptom score (TNSS) and modified Lund-Kennedy (L-K) endoscopy score. RESULTS Forty patients (21 female, 52.5%, median and IQR of age 52; 43.5-61) used LSD for 12 weeks. Initial analysis of dietary intervention in the whole group revealed a significant decrease in TNSS and each symptom assessed separately, and the L-K score. The group was further divided into two subgroups based on the distance between NSAID intake and the beginning of symptoms: patients with immediate (n = 9; 22.5%) or non-immediate (n = 31; 77.5%) symptoms. The absolute change in nasal obstruction, itching, TNSS, and L-K scores were significantly higher in patients with immediate than with non-immediate symptoms. CONCLUSION Results of the study indicate that patients with N-ERD and immediate symptoms may clinically benefit more from an LSD as an additional therapeutic option than patients with non-immediate symptoms.

Abstract
BACKGROUND Currently, there is a debate around the use of biological agents in the treatment of chronic sinusitis with nasal polyps. Therefore, this study's purpose was to assess the effectiveness of various biologics in the treatment of chronic rhinosinusitis with nasal polyps. METHODS A systematic and manual search was conducted for all relevant studies from inception to December 20, 2023. Two independent authors carried out the search, screening, assessment, and data extraction. Network meta-analysis was conducted using STATA 14 software. RESULTS Our analysis includes a comprehensive set of 19 studies. These studies compared the efficacy of four distinct biologic treatments. The results of reticulated Meta-analysis showed that Dupilumab (MD = - 1.85, 95% CI: - 2.47, - 1.24), Omalizumab (MD = - 1.30, 95% CI: - 1.90, - 0.70), Benralizumab (MD = - 0.84, 95% CI: - 1.66, - 0.03) and Mepolizumab (MD = - 1.48, 95% CI: - 2.22, - 0.74) were superior to placebo from the nasal polyp score(NPS), Dupilumab (MD = - 12.56, 95% CI: - 22.49,- 2.63) was superior to placebo from the Sino-Nasal Outcome Test-22(SNOT-22)score, and Dupilumab (MD = - 0.84, 95% CI: - 1.08, - 0.59) and Omalizumab (RR = - 0.51, 95% CI: - 0.83, - 0.19) were superior to placebo from the nasal congestion severity(NCS). In terms of cumulative sorting under the surface of the curve (SUCRA) values, Dupilumab was the best performer in the NPS (0.92), SNOT-22 score (0.70), and NCS (0.93); Four different biologics outperformed placebo in the NPS, SNOT-22 score, and NCS. CONCLUSION In patients with CRSwNP, based on the efficacy (NPS, (SNOT-22) score, NCS) and, dupilumab is the most efficacious for CRSwNP.

Abstract
OBJECTIVE In recent years, the clinical efficacy of medications for adenoid hypertrophy has been demonstrated. Topical nasal steroids have effects to shrink hypertrophic adenoids and improve symptoms of associated diseases. However, the mechanism which topical steroid administrations cause adenoid shrinkage remains unclear, herein, sensitivity for topical steroids in the mucosal epithelium of adenoids was evaluated histologically by comparing with tonsils. METHODS Histological analysis was performed on adenoids and tonsils removed from 32 pediatric patients with adenoid hypertrophy. In hematoxylin-eosin-stained specimens, the morphology of the mucosal epithelium and eosinophil infiltration were evaluated. The expression of the glucocorticoid receptor (GR), interleukin (IL)-4, and IL-25 in the mucosal epithelium was evaluated, and the staining intensity was scored as 0 (none), 1 (weak), and 2 (strong). The number of eosinophils and expression scores of GR, IL-4, and IL-25 were statistically compared between adenoids and tonsils and analyzed correlations with adenoids sizes. RESULTS Adenoids were covered with ciliated epithelium, and eosinophils in the mucosal epithelium and submucosal area was higher than tonsils (p < 0.05). GR expression in the most superficial layer of the mucosal epithelium was observed in adenoids, and the expression intensity score was higher than that in tonsils (p < 0.05). IL-4 and IL-25 were more widely expressed in the mucosal epithelium of adenoids than in tonsils, and their expression intensity scores were also higher than in tonsils (p < 0.05). A correlation was found between adenoid size and the intensity of IL-25 expression in the adenoid epithelium (p < 0.05). CONCLUSION Eosinophilic inflammations in adenoids mucosal epithelium could be one of etiology of adenoid hypertrophy, and the GR and eosinophilic inflammation in the adenoids mucosal epithelium might be target of topical nasal steroids to shrink hypertrophic adenoids.

Abstract
Although endoscopic sinus surgery (ESS) is beneficial in improving asthma symptoms, its impact on the lung function in patients with asthma and chronic rhinosinusitis remains unclear. We herein report a case of severe asthma with eosinophilic chronic rhinosinusitis, in which ESS substantially improved airflow limitation and concomitantly reduced fractional exhaled nitric oxide and blood eosinophil counts. ESS likely relieved airflow limitation by suppressing type 2 inflammatory pathways. This case highlights ESS as a promising strategy for achieving clinical remission in patients with severe asthma and chronic rhinosinusitis.

Abstract
PURPOSE To compare the effects of doxycycline (DOX) and conventional management in patients with refractory chronic rhinosinusitis and nasal polyps (CRSwNP). METHODS Six databases were searched to September 2023. We retrieved studies that compared improvements in refractory chronic sinusitis-related symptoms between DOX-treated and control groups. RESULTS DOX significantly reduced the Lund-Kennedy (LK) score [- 0.3670 (range - 0.6173; - 0.1166); I2 = 92.8%], the nasal polyposis score [- 0.9484 (- 1.2287; - 0.6680); I2 = 92.5%], the patient-reported Sinonasal Outcome Test (SNOT) score [- 0.3141 (- 0.4622; - 0.1660); I2 = 91.2%], and the nasal obstruction score [- 0.1813 (- 0.3382; - 0.0243); I2 = 86.2%]. On subgroup analyses by the measurement timepoints, the extent of nasal polyposis was significantly lower in the DOX group during treatment, at the end of treatment, and 4 and 8 weeks later. The LK scores also indicated improvements during treatment and at the end of treatment. The SNOT score tended to decrease with time in the treatment group. Nasal obstruction symptoms improved during treatment and 4 weeks later. CONCLUSION DOX enhances the postoperative endoscopic outcomes of refractory CRSwNP patients by reducing recurrent polyposis and inflammation.

Abstract
Chronic rhinosinusitis (CRS) is characterized by chronic inflammation of the sinonasal mucosa, affects over 12% of the US population, and costs over $20 billion annually. CRS can be divided into 2 major phenotypes based on whether nasal polyps are present (chronic rhinosinusitis with nasal polyps [CRSwNP]) or absent (chronic rhinosinusitis without nasal polyps). This grand rounds review will discuss the clinical approach to patients with CRSwNP, including typical presentations, workup, and currently available treatment options. Tools that physicians can use to assess subjective sinonasal symptoms, as well as objective measures of disease, will be reviewed. Additional focus will be on recognizing clinical comorbidities commonly associated with CRSwNP, including asthma, bronchiectasis, allergic rhinitis, and nonsteroidal anti-inflammatory drug-exacerbated respiratory disease. Clinical outcomes can be improved by providing a comprehensive approach to evaluating (and managing) patients with CRSwNP.

Abstract
INTRODUCTION Evidence on the early life risk factors of adult CRS, and the history of asthma and allergies across the life course, is limited. AIM To investigate relationships between respiratory infective/allergic conditions in childhood, and asthma and allergies across the life course and CRS in middle age. METHODS Data were from the population-based Tasmanian Longitudinal Health Study (TAHS) cohort, first studied in 1968 when aged 6-7 years (n = 8583) and serially followed into middle age (n = 3609). Using a well-accepted epidemiological definition, participants were assigned a CRS-severity subtype at age 53: no sinusitis/CRS (reference); past doctor diagnosis only; current symptoms without doctor diagnosis; and doctor-diagnosed CRS with current symptoms. Relationships with infective/allergic respiratory illnesses at age 7, and previously published asthma-allergy trajectories from 7 to 53 years, were examined using multinominal regression. RESULTS In middle age, 5.8% reported current CRS symptoms with 2.5% doctor-diagnosed. Childhood conditions associated with symptomatic doctor-diagnosed CRS included frequent head colds (multinomial odds ratio [mOR] = 2.04 (95% confidence interval [95% CI]: 1.24, 3.37)), frequent tonsillitis (mOR = 1.61 [95% CI: 1.00, 2.59]) and current childhood asthma (mOR = 2.23 [95% CI: 1.25, 3.98]). Life course trajectories that featured late-onset or persistent asthma and allergies were associated with all CRS subtypes in middle age; early-onset persistent asthma and allergies (mOR = 6.74, 95% CI: 2.76, 16.4); late-onset asthma allergies (mOR = 15.9, 95% CI: 8.06, 31.4), and late-onset hayfever (mOR = 3.02, 95% CI: 1.51, 6.06) were associated with symptomatic doctor-diagnosed CRS. CONCLUSION Current asthma, frequent head colds and tonsillitis at age 7 could signal a susceptible child who is at higher risk for CRS in mid-adult life and who might benefit from closer monitoring and/or proactive management. Concurrent asthma and allergies were strongly associated and are potential treatable traits of adult CRS.

Abstract
OBJECTIVE This narrative review explores alternative non-antibiotic antimicrobial agents for CRS management in adults. METHODS Alternative antimicrobial agents using EPOS 2020 guidelines as reference were selected, and articles dated from 2003 to 2022 in English, Portuguese, or Spanish using PubMed and EMBASE databases. The parameters analyzed included study design, evidence level, population characteristics, CRS characteristics, interventions, outcomes, sample size, randomization, blinding, and side effects. Reviews, unrelated contexts,in vitro experiments, and duplicates were excluded. RESULTS 148 articles were screened; 19 articles were selected for analysis. Randomized controlled trials and cohort studies assessing non-antibiotic antimicrobial treatments for CRS were included. Xylitol demonstrated effectiveness in reducing CRS symptoms, particularly SNOT-22 scores, surpassing saline irrigation benefits. Manuka honey showed potential microbiological benefits in recalcitrant CRS, but symptomatic and endoscopic improvements remained inconclusive. Baby shampoo irrigation improved nasal mucociliary clearance and postoperative outcomes. Colloidal silver nasal irrigation showed limited efficacy in reducing CRS symptoms or endoscopic scores. Povidone-Iodine (PI) nasal irrigation yielded mixed results, with varying effects on culture negativity and SNOT-20 scores. Bacteriophage treatment exhibited promise in decreasing specific bacterial strains and cytokine levels. CONCLUSION Non-antibiotic antimicrobial therapies, including xylitol, manuka honey, baby shampoo, colloidal silver, PI, bacteriophages, lactoferrin, and carrageenan offer potential alternatives for CRS in adult patients. Xylitol, baby shampoo, and PI presented benefits in improving symptoms and nasal endoscopic scores, however, the number of studies is limited for conclusive recommendations and safety assessments. CRS management should adopt a comprehensive approach, particularly for non-infectious or immune-related cases, moving beyond antibiotics. Antibiotics should be reserved for confirmed bacterial infections. Overall, this review shows the importance of exploring non-antibiotic therapies to enhance the management of CRS.

Effectiveness and safety profile of mepolizumab in chronic rhinosinusitis with nasal polyps: Real life data in a tertiary care. Am J Otolaryngol 2024; 45:104329. [PMID: 38696895 DOI: 10.1016/j.amjoto.2024.104329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Accepted: 04/19/2024] [Indexed: 05/04/2024]
Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by a type 2 pattern of inflammation. Mepolizumab was approved for the treatment of CRSwNP in 2021, it may be useful to evaluate its safety profile in a real-world setting. AIM This work aimed to prospectively highlight the effectiveness and safety profile of Mepolizumab in patients with CRSwNP enrolled in the Otorhinolaryngology Unit of the University Hospital of Messina. METHODS An observational cohort study was carried out considering all patients treated with Mepolizumab. A descriptive analysis was conducted reporting all demographic characteristics, endoscopic evaluations, and symptom conditions. RESULTS A total of 30 patients were treated with Mepolizumab, one patient discontinued the treatment. A statistically significant reduction in the Sino-Nasal Outcome Tests-22 (SNOT-22) and nasal polyp score (NPS) was shown at the 6th and 12th months compared to baseline values (SNOT-22, -33 and - 43, p < 0.001 for both comparisons; NPS, 0 and - 1, p < 0.001 for both comparisons). The median (Q1-Q3) sniffin' sticks test score increased from 7 (6-8) at the 6th month to 11 (10-13) at the 12th month. Seven patients (24.1 %) reported pain at the injection site, accompanied by redness, warmth, and tenderness within the first 24 h post-injection with a median duration of three days from the onset. CONCLUSIONS Given the optimal treatment response and the minimal adverse effects observed, clinicians should consider Mepolizumab a safe and effective treatment in CRSwNP patients. Further studies in real-life setting are necessary to better understand the long-term effects.

Abstract
OBJECTIVE Provide clinicians with current evidence for biologic therapy in children with chronic rhinosinusitis with nasal polyposis (CRSwNP). DATA SOURCES PubMed, MEDLINE, Cochrane, and clinical trial registries. REVIEW METHODS Key search terms related to biologic therapy in pediatric CRSwNP were identified via a structured query of current medical literature and clinical trial databases. CONCLUSIONS There is a dearth of active clinical trials and research studies for biologics targeting pediatric CRSwNP. There is an ongoing compassionate-use clinical trial involving Dupilumab for children with nasal polyps as well as only 1 published work specifically focused on Dupilumab for pediatric CRSwNP in the setting of aspirin-exacerbated respiratory disease. IMPLICATIONS FOR PRACTICE For children with atopic dermatitis, asthma, and chronic idiopathic urticaria, biologic therapies such as Omalizumab, Dupilumab, and Mepolizumab have gained Food and Drug Administration approval. The role of biologic therapy in pediatric CRSwNP demonstrates significant promise in the comprehensive management of the unified airway. Additional Phase III trials are necessary to broaden clinical indications for children with comorbid conditions and complex sinonasal disease.

Abstract
Chronic rhinosinusitis (CRS) represents a heterogeneous disorder primarily characterized by the persistent inflammation of the nasal cavity and paranasal sinuses. The subtype known as chronic rhinosinusitis with nasal polyposis (CRSwNP) is distinguished by a significantly elevated recurrence rate and augmented challenges in the management of nasal polyps. The pathogenesis underlying this subtype remains incompletely understood. Macrophages play a crucial role in mediating the immune system's response to inflammatory stimuli. These cells exhibit remarkable plasticity and heterogeneity, differentiating into either the pro-inflammatory M1 phenotype or the anti-inflammatory and reparative M2 phenotype depending on the surrounding microenvironment. In CRSwNP, macrophages demonstrate reduced production of Interleukin 10 (IL-10), compromised phagocytic activity, and decreased autophagy. Dysregulation of pro-resolving mediators may occur during the inflammatory resolution process, which could potentially hinder the adequate functioning of anti-inflammatory macrophages in facilitating resolution. Collectively, these factors may contribute to the prolonged inflammation observed in CRSwNP. Additionally, macrophages may enhance fibrin cross-linking through the release of factor XIII-A (FAXIII), promoting fibrin deposition and plasma protein retention. Macrophages also modulate vascular permeability by releasing Vascular endothelial growth factor (VEGF). Moreover, they may disrupt the balance between Matrix Metalloproteinases (MMPs) and Tissue Inhibitors of Metalloproteinases (TIMPs), which favors extracellular matrix (ECM) degradation, edema formation, and pseudocyst development. Accumulating evidence suggests a close association between macrophage infiltration and CRSwNP; however, the precise mechanisms underlying this relationship warrant further investigation. In different subtypes of CRSwNP, different macrophage phenotypic aggregations trigger different types of inflammatory features. Increasing evidence suggests that macrophage infiltration is closely associated with CRSwNP, but the mechanism and the relationship between macrophage typing and CRSwNP endophenotyping remain to be further explored. This review discusses the role of different types of macrophages in the pathogenesis of different types of CRSwNP and their contribution to polyp formation, in the hope that a better understanding of the role of macrophages in specific CRSwNP will contribute to a precise and individualized understanding of the disease.

Abstract
BACKGROUND There is evidence of pathophysiologic diversity in chronic rhinosinusitis with nasal polyps (CRSwNP), but data characterizing the molecular endotypes of CRSwNP and their association with treatment are lacking. OBJECTIVE This study aimed to identify gene signatures associated with CRSwNP endotypes, clinical features, and dupilumab treatment response. METHODS Nasal brushing samples were collected from 89 patients randomized to dupilumab 300 mg every 2 weeks or placebo in the SINUS-52 trial (NCT02898454). Microarrays were used to identify transcriptional clusters and assess the relationship between gene expression and baseline clinical features and clinical response to dupilumab. Endotype signatures were determined using differential expression analysis. RESULTS Two distinct transcriptional clusters (C1 and C2) were identified, both with elevated type 2 biomarkers. At baseline, C2 patients had higher mean Nasal Polyp Score and higher type 2 biomarker levels than C1 patients. At week 24, significant improvements in clinical outcomes (dupilumab vs placebo) were observed in both clusters, although the magnitude of improvements was significantly greater in C2 than in C1, and more C2 patients demonstrated clinically meaningful responses. Gene set enrichment analysis supported the existence of 2 molecular endotypes: C2 was enriched in genes associated with type 2 inflammation (including periostin, cadherin-26, and type 2 cysteine protease inhibitors), while C1 was enriched in genes associated with T cell activation and IL-12 production. CONCLUSIONS Two distinct gene signatures associated with CRSwNP clinical features were identified; the endotype signatures were associated with clinical outcome measures and magnitude of dupilumab response.

Abstract
The epithelial barriers of the skin, gut, and respiratory tract are critical interfaces between the environment and the host, and they orchestrate both homeostatic and pathogenic immune responses. The mechanisms underlying epithelial barrier dysfunction in allergic and inflammatory conditions, such as atopic dermatitis, food allergy, eosinophilic oesophagitis, allergic rhinitis, chronic rhinosinusitis, and asthma, are complex and influenced by the exposome, microbiome, individual genetics, and epigenetics. Here, we review the role of the epithelial barriers of the skin, digestive tract, and airways in maintaining homeostasis, how they influence the occurrence and progression of allergic and inflammatory conditions, how current treatments target the epithelium to improve symptoms of these disorders, and what the unmet needs are in the identification and treatment of epithelial disorders.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by type 2 inflammation in the United States, but the actual roles that eosinophils play in CRSwNP remain largely unclear. OBJECTIVE To reveal the roles and heterogeneity of eosinophils in nasal polyp (NP) tissue, we performed single cell RNA sequencing (scRNA-Seq) analysis of NP tissue. METHODS Sinonasal tissues (NP and control sinus tissue) and patient matched peripheral blood (PB) samples were obtained from 5 control patients and 5 patients with CRSwNP. Eosinophils were enriched before processing for scRNA-Seq. The gene expression profiles in eosinophils were determined by microwell-based scRNA-Seq technology (BD Rhapsody platform). We predicted the overall function of NP eosinophils by Gene Ontology (geneontology.org) enrichment and pathway analyses and confirmed expression of selected genes by flow cytometry. RESULTS After filtering out contaminating cells, we detected 5,542 eosinophils from control PB, 3,883 eosinophils from CRSwNP PB, 101 eosinophils from control sinus tissues (not included in further analyses), and 9,727 eosinophils from NPs by scRNA-Seq. We found that 204 genes were downregulated and 354 genes upregulated in NP eosinophils compared to all PB eosinophils (>1.5-fold, Padj < .05). Upregulated genes in NP eosinophils were associated with activation, cytokine-mediated signaling, growth factor activity, NF-κB signaling, and antiapoptotic molecules. NP eosinophils displayed 4 clusters revealing potential heterogeneity of eosinophils in NP tissue. CONCLUSIONS Elevated eosinophils in NP tissue appear to exist in several subtypes that may play important pathogenic roles in CRSwNP, in part by controlling inflammation and hyperproliferation of other cells.

Abstract
INTRODUCTION The recent approval of Dupilumab has profoundly revolutionized the management of patients affected by severe and recalcitrant Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). However, a review that summarizes the results of real-life studies and compares them to phase 3 studies SINUS-24 and 52 is still lacking. MATERIALS AND METHODS A search of all real-life studies published from 2019 to 2023 was performed. Patients characteristics at baseline and 6 and 12 months after starting Dupilumab were extracted and compared to those from phase 3 trials: age, sex, smoking habits, comorbid asthma and aspirin-exacerbated respiratory disease (AERD), previous endoscopic sinus surgery (ESS), hematic eosinophils and total IgE, NasalAQ2 Polyps Score (NPS), smell, SNOT-22, adverse events (AEs), and response to treatment. RESULTS 15 papers were included with an overall number of 1658 patients. A higher rate of comorbidities and previous ESS was found in patients from real-life studies. In addition, they had worse smell and SNOT-22 at baseline compared to patients from SINUS-24 and 52. Comorbid and post-ESS patients tended to have a faster NPS and SNOT-22 improvement, although the absolute values were not clinically relevant. A more extensive surgery and a number of ESS ≥ 2 were related to worse olfactory outcomes, probably due to iatrogenic damage. No correlation was found between hematic eosinophils and outcomes. AEs were reported by 12.4% of patients and 2.2% had to discontinue dupilumab. Weight gain was an emergent AE (0.8%), probably related to the restored sense of smell and taste. Non-responders were 3.5% and they were switched to systemic steroid, ESS, or another biologic. CONCLUSION Despite some differences in prescription criteria between countries, dupilumab was demonstrated to be effective even in the real-life scenario. However, emerging AEs and possible unknown long-term AEs of a likely lifelong therapy should be considered.

Abstract
BACKGROUND Aspergillus is one of the most common pathogens causing fungal allergy in the respiratory tract. Serum Aspergillus fumigatus-specific immunoglobulin G (Af-sIgG) levels have been used as a biomarker for the diagnosis and treatment response monitoring in airway allergic diseases such as allergic bronchopulmonary aspergillosis and allergic fungal rhinosinusitis. However, its role in common primary chronic rhinosinusitis (CRS) was unclear. OBJECTIVE This study aims to evaluate whether serum Af-sIgG level could serve as a biomarker for the disease presentation of primary CRS. METHODS We obtained serum Af-sIgG levels from patients diagnosed as bilateral primary CRS refractory to medical treatment and evaluated the correlations between serum Af-sIgG levels and disease severity in patients with type 2 (T2) and non-T2 CRS. RESULTS Patients with T2 CRS exhibited significantly higher serum Af-sIgG levels than non-T2 CRS patients. The cut-off value of serum Af-sIgG in T2 CRS was 20.9 mg/L, with an odds ratio of 3.8 (95% CI 1.17-12.20, P = .026). Furthermore, serum Af-sIgG levels were positively correlated with symptom scores evaluated by the Sino-Nasal Outcome Test-22 (SNOT-22) scores in T2 patients (P = .009). While stratified by SNOT-22 total scores, patients with severe disease had higher serum Af-sIgG levels only in T2 CRS (P = .034). In individual domains of SNOT-22 analysis, serum Af-sIgG levels showed a significant correlation with "ear/facial" symptom scores in the T2 group (P < .001). CONCLUSIONS Serum Af-sIgG levels may serve as a supplementary objective biomarker that correlates with identification and subjective measurements of T2 CRS, and may be associated with symptoms arising from Eustachian tube dysfunction.

Abstract
Tight junction (TJ) proteins establish a physical barrier between epithelial cells, playing a crucial role in maintaining tissue homeostasis by safeguarding host tissues against pathogens, allergens, antigens, irritants, etc. Recently, an increasing number of studies have demonstrated that abnormal expression of TJs plays an essential role in the development and progression of inflammatory airway diseases, including chronic obstructive pulmonary disease, asthma, allergic rhinitis, and chronic rhinosinusitis (CRS) with or without nasal polyps. Among them, CRS with nasal polyps is a prevalent chronic inflammatory disease that affects the nasal cavity and paranasal sinuses, leading to a poor prognosis and significantly impacting patients' quality of life. Its pathogenesis primarily involves dysfunction of the nasal epithelial barrier, impaired mucociliary clearance, disordered immune response, and excessive tissue remodeling. Numerous studies have elucidated the pivotal role of TJs in both the pathogenesis and response to traditional therapies in CRS. We therefore to review and discuss potential factors contributing to impair and repair of TJs in the nasal epithelium based on their structure, function, and formation process.

Deep immune profiling of chronic rhinosinusitis in allergic and non-allergic cohorts using mass cytometry. Clin Immunol 2024; 262:110174. [PMID: 38462155 DOI: 10.1016/j.clim.2024.110174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 03/12/2024]
Abstract
Chronic rhinosinusitis (CRS) is a persistent nasal and paranasal sinus mucosa inflammation comprising two phenotypes, namely CRS with nasal polyps (CRSwNP) and without (CRSsNP). CRSwNP can be associated with asthma and hypersensitivity to non-steroidal anti-inflammatory drug (NSAID) in a syndrome known as NSAID-exacerbated respiratory disease (N-ERD). Furthermore, CRS frequently intertwines with respiratory allergies. This study investigated levels of 33 different nasal and serum cytokines and phenotypic characteristics of peripheral blood mononuclear cells (PBMCs) within cohorts of CRS patients (n = 24), additionally examining the influence of comorbid respiratory allergies by mass cytometry. N-ERD patients showed heightened type 2 nasal cytokine levels. Mass cytometry revealed increased activated naive B cell levels in CRSwNP and N-ERD, while resting naive B cells were higher in CRSsNP. Th2a cell levels were significantly elevated in allergic subjects, but not in CRS groups. In conclusion, there are distinct immunological features in PBMCs of CRS phenotypes and allergy.

Abstract
OBJECTIVE Our aim in this study is to identify the core genes of chronic rhinosinusitis with nasal polyps and analyze the correlations between it and inflammation-related genes. METHODS GSE72713 dataset containing gene expression data of ECRSwNP, nonECRSwNP and healthy samples was obtained from Gene Expression Omnibus (GEO) and filtered by limma to identify DEGs among three groups, then the functions and correlated pathways of DEGs were analyzed using GO and KEGG. The core DEGs were selected by the intersection of DEGs and the PPI network was constructed via STRING. The correlations between the expression levels of CRSwNP core gene and inflammation-related genes were analyzed via the Mann-Whitney U test. RESULTS The DEGs among ECRSwNP, nonECRSwNP, and CTRL were filtered respectively, and enrichment analysis showed they were associated with olfaction and/or immune responses. The PPI network was constructed by 7 core DEGs obtained via the intersection among three groups, and ALOX15 was confirmed as the core gene in the network. Subsequently, the correlations between the expression levels of ALOX15 and inflammation-related genes were illustrated. CONCLUSION In this study, the core gene ALOX15 was selected from the DEGs among ECRSwNP, nonECRSwNP, and CTRL. IL5, IL1RL1, and IL1RAP were found to exhibit a significant positive correlation with ALOX15. LEVEL OF EVIDENCE Level 3.

Abstract
Chronic rhinosinusitis with nasal polyposis is a common inflammatory condition, with subtypes like aspirin-exacerbated respiratory disease, allergic fungal rhinosinusitis, and central compartment atopic disease sharing a common type 2 inflammatory pathway. Respiratory biologic therapies have been developed that target type 2 inflammation. In this article, we discuss the use of respiratory biologic therapies for nasal polyposis in general, as well as within the various subtypes of nasal polyps. Further, we discuss future roles of novel biologic therapies targeting type 2 inflammation in nasal polyposis.

All chronic rhinosinusitis endotype clusters demonstrate improvement in patient-reported and clinical outcome measures after endoscopic sinus surgery. Int Forum Allergy Rhinol 2024; 14:765-774.

Abstract
BACKGROUND It is unclear whether chronic rhinosinusitis (CRS) endotypes show a differential response to endoscopic sinus surgery (ESS). We explored patient mucous inflammatory cytokine expression and associations with patient-reported and clinically measured post-operative outcome measures. METHODS Patients with CRS were prospectively recruited between 2016 and 2021 into a national multicenter, observational study. Mucus was collected from the olfactory cleft preoperatively and evaluated for 26 biomarkers using cluster analysis. Patient-reported outcome measures included the 22-item Sino-Nasal Outcome Test (SNOT-22) and Questionnaire of Olfactory Dysfunction (QOD). Additional clinical measures of disease severity included threshold, discrimination, and identification (TDI) scores using "Sniffin' Sticks" testing and Lund-Kennedy endoscopic score (LKES). RESULTS A total of 115 patients were clustered into type 2 inflammatory, non-type 2 inflammatory, noninflammatory, and two indeterminate clusters based on individual protein levels. Overall, the type 2 inflammatory cluster was found to have the highest mean improvement in both SNOT-22 (-28.3 [standard deviation, ±16.2]) and TDI (6.5 [standard deviation, ±7.9]) scores 6 months after ESS. However, on average, all endotype clusters demonstrated improvement in all outcome measures after ESS without statistically significant between-group differences in SNOT-22 (p = 0.738), QOD (p = 0.306), TDI (p = 0.358), or LKES (p = 0.514) measures. CONCLUSIONS All CRS endotype clusters responded favorably to surgery and showed improvements in patient-reported and objective outcome measures. Thus, ESS should be considered a more generalized CRS therapy, and benefits appear to not be limited to specific endotypes.

Abstract
PURPOSE Dupilumab, an anti-interleukin-4 receptor alpha monoclonal antibody, is a new treatment for severe uncontrolled chronic rhinosinusitis with nasal polyps. However, data on the effect of dupilumab on histological changes in nasal polyp tissue are lacking. We aimed to investigate the effect of dupilumab on real-life clinical conditions and nasal polyp tissues from patients with eosinophilic chronic rhinosinusitis (ECRS), which is a refractory subtype. METHODS We conducted an open-label, prospective, observational, single-centre study on 63 patients with refractory ECRS on the basis of the criteria of the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis Study. These patients had a history of surgery and received dupilumab for 24 weeks. Patient-reported sinonasal symptoms, T&T olfactometry and nasal polyp scores were prospectively evaluated. In 23 patients with residual nasal polyps following dupilumab treatment, changes in systemic and local periostin expression, and total collagen deposition in nasal polyp tissues were investigated before and after dupilumab administration. RESULTS Dupilumab rapidly improved sinonasal symptoms and reduced the nasal polyp score 24 weeks after initiation. 40 (63.5%) patients had resolution of nasal polyps, but the reduction was limited in the remaining 23 (36.5%) patients. Periostin expression in serum and nasal lavage fluid was decreased, whereas periostin and the total collagen deposition area in subepithelial tissues in residual nasal polyps were enhanced after dupilumab administration. CONCLUSION Dupilumab improves sinonasal symptoms and reduces the nasal polyp score in refractory ECRS. Periostin-associated tissue fibrosis may be involved in the differential effect of dupilumab on nasal polyp reduction.

Abstract
Allergy and asthma prevalence vary across different subsets of chronic rhinosinusitis with nasal polyposis. In this article, the authors investigate the management of allergy and asthma within populations of patients with aspirin-exacerbated respiratory disease, allergic fungal rhinosinusitis, and central compartment atopic disease. Topical steroids, nasal rinses, and endoscopic sinus surgery are frequently employed in the management of nasal polyposis. Further, other causes of upper and lower airway inflammation like allergy and asthma should be considered in the overall treatment plan in order to optimize outcomes.

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
Chronic rhinosinusitis (CRS) is a heterogenic disease characterized by persistent mucosal inflammation of the upper airway. Researches of CRS have progressed from phenotype-based to endotype-based, looking more deeply into molecular biomarkers, signaling pathways, and immune microenvironment. Single-cell RNA sequencing is an effective tool in analyzing composition, function, and interaction of cells in disease microenvironment at transcriptome level, showing great advantage in analyzing potential biomarkers, pathogenesis, and heterogeneity of chronic airway inflammation in an unbiased manner. In this article, we will review the latest advances in scRNA-seq studies of CRS to provide new perspectives for the diagnosis and treatment of this heterogeneous disease.

Abstract
BACKGROUND In recent years, significant improvements have been made in the treatment options for uncontrolled chronic rhinosinusitis (CRS) refractory to standard medical and surgical therapy. This is the result of a better understanding of the pathophysiology and the resulting development of biologicals for CRS with nasal polyps (CRSwNP). However, biologics are not (yet) available for all patients in Europe. OBJECTIVE Based on the session "Difficult-to-treat CRS, when biologics are not available" at the 29th Congress of the European Rhinologic Society (ERS) 2023 in Sofia, Bulgaria, the treatment options for uncontrolled CRS with the exclusion of biologics will be discussed. MATERIALS AND METHODS The content of the presentations "Is there a place for antibiotics?" "Indications for revision surgery," "Novel systemic treatment options," "Novel local treatment options," and "Phototherapy for nasal polyps" are outlined and supported by a review of the literature. RESULTS Various treatment options are available for managing uncontrolled CRS, even if biologic treatments are unavailable. Treatment options for type‑2 (T2) CRS include steroid rinses, repeated short-term oral steroids, steroid-eluting stents, and extended sinus surgery. In the case of nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (NERD), acetylsalicylic acid (ASA) desensitization can be considered. Non-T2 endotypes or CRS without nasal polyps (CRSsNP) may benefit from several weeks of macrolides and xylitol rinses. CONCLUSION To accurately assess the efficacy of second-line therapies for treatment of difficult-to-treat CRS within an endotype-specific framework, additional controlled clinical trials are needed that take into account the heterogeneity of CRS endotypes.

Abstract
Some studies have demonstrated the effects of particulate matter (PM) on chronic rhinosinusitis with nasal polyps (CRSwNP) development, as well as the therapeutic role of retinoic acid (RA) in nasal polypogenesis. However, the immunologic effect of PM in innate lymphoid cells (ILCs) and the exact mechanism of the therapeutic effect of RA remain unclear. Therefore, the present study investigated the effects of fine-dust-induced inflammation in CRSwNP and the mechanisms of the therapeutic effect of RA. PM2.5 exposure exacerbated pathological damage in the nasal mucosa of mice with nasal polyps (NP) via upregulation of type 2 inflammation. Additionally, PM2.5 exposure increased the expression of type 2 cytokines and epithelial-cell-derived cytokines (IL-33 and IL-25) significantly, as well as the ILC populations in human-NP-derived epithelial cells (HNECs). Moreover, RA supplementation significantly increased the expression of ILCreg in Lin-CD45+CD127+ cells, which in turn increased the levels of the anti-inflammatory cytokine IL-10. The findings suggest that PM2.5 exposures could aggravate the CRSwNP type 2 inflammation, and RA treatment may ameliorate fine-dust-induced inflammation by modulating the innate immune response.

Abstract
Background and Objectives: Real-life data on the efficacy of biologic agents (BAs) on asthma-comorbid CRSwNP are needed. Our primary goal is to investigate the effects of BAs on CRSwNP symptoms, as well as endoscopic and tomography scores. Our secondary goal is to show a reduction in the frequency of acute sinusitis exacerbations and the need for surgery. Materials and Methods: We conducted a multicenter, retrospective, real-life study. We screened the patients with asthma-comorbid CRSwNP treated with omalizumab or mepolizumab. A total of 69 patients (40 F/29 M; omalizumab n = 55, mepolizumab n = 14) were enrolled. We compared the visual analog scale (VAS), sinonasal outcome test-22 (SNOT-22), nasal congestion score (NCS), Lund-Mackay computed tomography score (LMS), and total endoscopic polyp scores (TPS) before and after BAs. We evaluated the endoscopic sinus surgery (ESS) and acute exacerbations of chronic rhinosinusitis (AECRS) frequencies separately, according to the BAs. Results: The overall median (min-max) age was 43 (21-69) years. The median (min-max) of biologic therapy duration was 35 (4-113) months for omalizumab and 13.5 (6-32) for mepolizumab. Significant improvements were seen in VAS, SNOT-22, and NCS with omalizumab and mepolizumab. A significant decrease was observed in TPS with omalizumab [95% CI: 0-4] (p < 0.001), but not with mepolizumab [95% CI: -0.5-2] (p = 0.335). The frequency of ESS and AECRS were significantly reduced with omalizumab [95% CI: 2-3] (p < 0.001) and [95% CI: 2-5] (p < 0.001); and mepolizumab [95% CI: 0-2] (p = 0.002) and [95% CI: 2-8.5] (p < 0.001), respectively. There was no significant difference in LMS with either of the BAs. Conclusions: Omalizumab and mepolizumab can provide a significant improvement in the sinonasal symptom scores. BAs are promising agents for CRSwNP patients with frequent exacerbations and multiple surgeries.

Abstract
OBJECTIVES To develop and assess the validity of a novel allergy-specific domain for the 22-item sino-nasal outcomes test (SNOT-22), to provide a new tool that efficiently quantifies the impact of allergic rhinitis (AR) concurrent with chronic rhinosinusitis. STUDY DESIGN Prospective validation study. SETTING Tertiary care hospital and community-based clinic. METHODS Proposed items were developed based on clinician and patient input, and further assessed via factor analysis and for internal consistency (n = 1987). Items were then additionally assessed for convergent and discriminant validity (n = 415), applying data from concurrent completions of the Nasal Obstruction and Septoplasty Effectiveness Scale (NOSE), Mini-Rhinoconjunctivitis Quality-of-Life Questionnaire (MiniRQLQ), and validated global health assessments. Assessments of intra-rater reliability, responsiveness to change, and qualitative input were also performed. RESULTS Factor analysis demonstrated that proposed allergy items mapped to a single domain. Items were internally consistent (Cronbach α: 0.80 within domain, 0.91 within all SNOT). In assessments of convergent validity, domain scores were associated with MiniRQLQ (Spearman's ρ: 0.46, 95% confidence interval [CI]: 0.30-0.59) and NOSE scores (0.36, 95% CI: 0.27-0.44). The novel items also discriminated among clinical states: a 1-point increase in domain score was associated with an 8.32 (95% CI: 5.43-12.75) increase in the odds of prompting a visit for allergy-related symptoms and a 1.52 (95% CI: 1.13-2.05) increase in the odds of positive allergy testing. Intra-rater reliability was substantial (Cohen's κ: 0.8, 95% CI: 0.8-0.9), and responsiveness to change was demonstrated (mean difference: -0.6, 95% CI: -0.8 to -0.4). CONCLUSIONS This novel domain is a valid, efficient measure of AR alongside rhinosinusitis.

World Allergy Organ J 2024; 17:100878. [PMID: 38445296 PMCID: PMC10914524 DOI: 10.1016/j.waojou.2024.100878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 01/23/2024] [Accepted: 01/26/2024] [Indexed: 03/07/2024] Open
Abstract
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) presents a high rate of postoperative recurrence, but its recurrent mechanisms are not fully clarified. In this study, we aim to explore biomarkers associated with the recurrence of CRSwNP and shed light on the underlying recurrent mechanisms using serum proteomics. Methods A prospective cohort of CRSwNP patients was conducted, and serum samples were subjected to proteomic profiling. Participants were followed up for 2 years and divided into non-Recurrence and Recurrence groups and differentially expressed proteins (DEPs) were compared. The top 3 DEPs were validated in the serum and tissue samples in a validation cohort, and their predictive values for recurrence and their associations with macrophages were evaluated. In vitro, circulating macrophages were utilized to explore the influence of candidate proteins on macrophage polarization in underlying recurrent mechanisms of CRSwNP. Results Sixteen CRSwNP patients completed the follow-up schedule, including 10 patients in the non-Recurrence group and 6 patients in the Recurrence group. Serum proteomics revealed a distinctive protein expression profile between the 2 groups. A validation cohort comprising 51 non-recurrent and 24 recurrent CRSwNP patients was recruited. Enzyme-linked immunosorbent assay (ELISA) results revealed that circulating levels of CSF1R and CDC42 were significantly higher, and DHRS9 levels were lower in the Recurrence group in comparison with the non-Recurrence group. In addition, tissue CSF1R and CDC42 were identified to be enhanced in the Recurrence group compared to the non-Recurrence group. Receiver-operated characteristic (ROC) curves and Kaplan-Meier survival analysis suggest that both serum and tissue CSF1R were associated with the risk of postoperative recurrence. Tissue immunofluorescence (IF) revealed that CSF1R was enhanced in the tissues of patients with recurrence, especially in the mesenchymal region. Multiplex IF highlighted that CSF1R was significantly co-expressed with M2 macrophage markers. In vitro experiments confirmed that CSF1R overexpression promoted macrophage M2 polarization and cytokine production. Conclusion Serum proteomic signatures may affect postoperative recurrence in CRSwNP patients. CSF1R is a potential biomarker for predicting CRSwNP recurrence. Mechanistically, the recurrence of CRSwNP appears to involve the CSF1R-driven M2 polarization process.

Abstract
Introduction Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the sinonasal mucosa with distinct endotypes including type 2 (T2) high eosinophilic CRS with nasal polyps (eCRSwNP), T2 low non-eosinophilic CRS with nasal polyps (neCRSwNP), and CRS without nasal polyps (CRSsNP). Methods Given the heterogeneity of disease, we hypothesized that assessment of single cell RNA sequencing (scRNA-seq) across this spectrum of disease would reveal connections between infiltrating and activated immune cells and the epithelial and stromal populations that reside in sinonasal tissue. Results Here we find increased expression of genes encoding glycolytic enzymes in epithelial cells (EpCs), stromal cells, and memory T-cell subsets from patients with eCRSwNP, as compared to healthy controls. In basal EpCs, this is associated with a program of cell motility and Rho GTPase effector expression. Across both stromal and immune subsets, glycolytic programming was associated with extracellular matrix interactions, proteoglycan generation, and collagen formation. Furthermore, we report increased cell-cell interactions between EpCs and stromal/immune cells in eCRSwNP compared to healthy control tissue, and we nominate candidate receptor-ligand pairs that may drive tissue remodeling. Discussion These findings support a role for glycolytic reprograming in T2-elicited tissue remodeling and implicate increased cellular crosstalk in eCRSwNP.

Inflamm Res 2024:10.1007/s00011-024-01855-y. [PMID: 38363325 DOI: 10.1007/s00011-024-01855-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 01/19/2024] [Accepted: 01/26/2024] [Indexed: 02/17/2024] Open
Abstract
OBJECTIVE The treatment of eosinophilic chronic rhinosinusitis with nasal polyps (E-CRSwNP) remains a challenge due to its complex pathogenesis. Inositol polyphosphate-4-phosphatase type IA (INPP4A), a lipid phosphatase, has been implicated in allergic asthma. However, the expression and function of INPP4A in E-CRSwNP remain unclear. This study aims to investigate the role of INPP4A in macrophages in E-CRSwNP. METHODS We assessed the expression of INPP4A in human and mouse nasal mucosal tissues via immunofluorescence staining. THP-1 cells were cultured and exposed to various cytokines to investigate the regulation of INPP4A expression and its functional role. Additionally, we established a murine nasal polyp (NP) model and administrated an INPP4A-overexpressing lentivirus evaluate its impact on NP. RESULTS The percentage of INPP4A + CD68 + macrophages among total macrophages decreased in the E-CRSwNP group compared to the control and the non-eosinophilic CRSwNP (NE-CRSwNP) groups, exhibiting an inverse correlation with an increased percentage of CD206 + CD68 + M2 macrophages among total macrophages. Overexpression of INPP4A led to a reduced percentage of THP-1 cells polarizing towards the M2 phenotype, accompanied by decreased levels of associated chemotactic factors including CCL18, CCL22, CCL24, and CCL26. We also validated the involvement of the PI3K-AKT pathway in the function of INPP4A in vitro. Furthermore, INPP4A overexpression in the murine NP model resulted in the attenuation of eosinophilic inflammation in the nasal mucosa. CONCLUSIONS INPP4A deficiency promotes macrophage polarization towards the M2 phenotype, leading to the secretion of chemokines that recruit eosinophils and Th2 cells, thereby amplifying eosinophilic inflammation in E-CRSwNP. INPP4A may exert a suppressive role in eosinophilic inflammation and could potentially serve as a novel therapeutic strategy.

Abstract
Objective:Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) play important roles in the poor prognosis of different inflammatory and neoplastic diseases, but their effects on postoperative recurrence of chronic rhinosinusitis(CRS) are unknown. The aim of this study was to investigate the correlation between preoperative NLR and PLR and the risk of postoperative recurrence in CRS. Methods:Clinical data were collected from patients with CRS who underwent initial functional endoscopic sinus surgery from October 2018 to February 2022 at our institution. Follow-up was until February 2023, and the study endpoint was defined as patient postoperative recurrence or follow-up time up to date. The optimal preoperative NLR and PLR threshold values were obtained based on subject work curve analysis, and they were divided into high and low level subgroups, respectively, and the clinical characteristics and postoperative recurrence rates of patients were compared between groups; patients were divided into non-recurrent CRS and recurrent CRS according to their postoperative recurrence, and Kaplan-Meier survival curves and logistic regression analysis were performed to explore the correlation between NLR and PLR and CRS The correlation between NLR and PLR and postoperative recurrence was investigated by Kaplan-Meier survival curve and logistic regression analysis. Results:A total of 630 patients with CRS were included, including 382 and 140 patients with high NLR and high PLR, respectively. The postoperative recurrence rates of CRS patients in the high NLR and high PLR groups were significantly higher than those in the low NLR and low PLR groups(P<0.05). The recurrent CRS had higher NLR and PLR levels and higher proportion of high NLR and high PLR than the non-recurrent CRS(P<0.05), and similarly the duration of recurrent CRS and the rate of allergic rhinitis with recurrence were significantly higher than the non-recurrent CRS(P<0.05). Kaplan-Meier survival curves showed that postoperative CRS was significantly higher in the high NLR and high PLR groups compared with the low NLR and low PLR groups. recurrence was significantly higher(P<0.05). In addition, logistic regression analysis showed that high NLR, high PLR, disease duration, and combined allergic rhinitis were significantly associated with an increased risk of postoperative recurrence of CRS(P<0.05). Conclusion:Both high preoperative NLR and high PLR are independent risk factors for postoperative recurrence of CRS, and they are expected to be new indicators for postoperative prognostic assessment and risk stratification of CRS patients. In addition, disease duration and comorbid allergic rhinitis were significantly associated with the risk of postoperative recurrence of CRS.

Abstract
PURPOSE OF REVIEW In the past year, the endotype of chronic rhinosinusitis (CRS) has been studied from a new perspective. Eosinophilic and neutrophilic inflammation are not independent processes in the pathogenesis of CRS. In this review, we will focus on recent research on mixed eosinophilic-neutrophilic inflammation in CRS and discuss the mechanism and potential treatments. RECENT FINDINGS Traditionally, patients with eosinophilic CRS (ECRS) present with severe clinical manifestations, comorbidities, and a higher recurrence rate. Recent studies have found that approximately 40% of patients with ECRS present with neutrophilic infiltration, while patients with predominantly eosinophilic infiltration along with neutrophilic inflammation present with more complex inflammation, clinical manifestations and exhibit refractory characteristics. SUMMARY The complex inflammatory profile and refractory clinical characteristics of mixed eosinophilic-neutrophilic inflammation in CRS are current challenges for clinicians. We summarize the features of eosinophilic and neutrophilic inflammation and current studies on the mechanisms of mixed eosinophilic-neutrophilic inflammation and suggest potentially effective therapeutic methods. We hope that this review will help with determining precise treatment options for patients.

Abstract
PURPOSE OF REVIEW Aspirin-exacerbated respiratory disease (AERD) is a syndrome of high type 2 inflammation and is known to critically involve mast cell activation. The mast cell is an important cell in the baseline inflammatory processes in the upper and lower airway by maintaining and amplifying type 2 inflammation. But it also is prominent in the hypersensitivity reaction to COX-1 inhibition which defines this condition. RECENT FINDINGS Recent work highlights the mast cell as a focal point in AERD pathogenesis. Using AERD as a specific model of both high type 2 asthma and chronic sinusitis, the role of mast cell activity can be better understood in other aspects of airway inflammation. Further dissecting out the mechanism of COX-1-mediated mast cell activation in AERD will be an important next phase in our understanding of NSAID-induced hypersensitivity as well as AERD pathophysiology.

Chronic rhinosinusitis (CRS) is a persistent inflammatory disease of the nasal cavity and paranasal sinuses. Traditional classification is denoted by the presence (CRSwNP) or absence of nasal polyps (CRSsNP). Particularly, CRSwNP is distinguished by the presence of infiltrating cells and inflammatory markers in the nasal mucosa. Patients with CRSwNP in Western countries predominantly display a type 2 endotype, whereas those in Asian regions display a mixed type 2 endotype. Nevertheless, recent transcriptome analyses have revealed two types of nasal polyps - type 2 and non-type 2 polyps, suggesting that geographical differences in endotypes likely resulted from the different proportions of each endotype. Moreover, various endotypes of CRSsNP have been identified, making phenotype a crucial factor for predicting treatment efficacy. Type 2 endotypes, designated as eosinophilic CRS (ECRS) in Japan, are characterized by severe eosinophilic infiltration into the paranasal sinus tissue and are particularly refractory. In this review, we discuss the latest developments in ECRS. We also provide recent findings on the involvement of nasal epithelial cells in pathogenesis.

Abstract
BACKGROUND AND OBJECTIVE The terms "functional" and "radical" paranasal sinus surgery were often considered to be different operations which were mutually exclusive. This overview aims to look at the basics of these terms and surgical procedures and to work out the resulting surgical concepts for clinically relevant indications. MATERIAL AND METHODS Selective literature analysis using the data base PubMed, corresponding textbooks and resulting secondary literature regarding functional and radical or extended paranasal sinus surgery. Similarly, the current literature regarding clinically relevant indications for sinus surgery were analyzed. RESULTS AND CONCLUSION Modern pathophysiological knowledge, anatomically and pathophysiologically substantiated endoscopic surgical procedures and the usage of up to date technical possibilities have resulted in concepts which combine functional and so-called radical or extended surgery of the paranasal sinuses that complement each other and sometimes even overlap. The preoperative diagnosis and definition of underlying diseases are decisive and should be as precise as possible, as the extent and surgical details mainly depend on them: a sole creation of free drainage pathways, an additional creation of anatomical access for subsequent topical treatment or a complete (radical) removal of a pathological process.

Abstract
BACKGROUND Eosinophilic chronic rhinosinusitis (eCRS) is a type 2 inflammatory disease that frequently recurs after surgery. In recent years, dupilumab has been available for the treatment of refractory chronic rhinosinusitis since 2020 in Japan. Although there are some reports of its usefulness, there are not enough reports of its clinical efficacy for longer than 1 year, especially for olfactory recovery. METHODS Twenty patients with eCRS who had recurrence after surgery and had been receiving dupilumab were enrolled retrospectively. The nasal polyp score (NPS), computed tomography (CT) score, T&T olfactometer, and olfactory cleft opacification on CT were evaluated at baseline, at an average of 5.1 months later (short term), and at an average of 18.3 months later (long term). RESULTS At the short-term evaluation, there were significant improvements in the NPS and CT scores (P < .001, P = .008, respectively). The CT score was further improved at the long-term evaluation compared to the short-term evaluation (P = .018) and baseline (P = .008). T&T detection/recognition thresholds and olfactory cleft opacification showed significant improvements only at the long-term evaluation compared to baseline (P = .002, P = .006, and, P = .006, respectively). CONCLUSION The NPS remained improved, and the CT score showed further improvement with long-term treatment, whereas olfactory function and olfactory cleft opacification showed significant improvement only after long-term treatment. There was a dissociation between the time to improve in the NPS and CT scores and the time to improve in olfactory function and olfactory cleft opacification. Based on these results, dupilumab should be administered for longer than 1 year, especially for olfactory function.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent inflammation of the sinonasal mucosa. CRSwNP treatments are associated with inconsistent efficacy and recurrence of symptoms. Dynorphin 1-17 (DYN 1-17) and its fragments have been shown to modulate the immune response in various inflammatory conditions. This study aimed to investigate the effect of different pH and degrees of inflammation on DYN 1-17 metabolism in human CRSwNP tissues. DYN 1-17 was incubated with grade 3 and grade 4 inflamed tissues of CRSwNP patients at pH 5.5 and pH 7.4 over a range of incubation periods. The resulting fragments were identified using an ultra-performance liquid chromatography (UPLC) system coupled to quadrupole-time of flight (QTOF) mass spectrometry based on their accurate mass. The rate of DYN 1-17 fragmentation was slower at pH 5.5 in comparison to pH 7.4. The extent and rate of metabolism of DYN 1-17 were much lower in grade 3 inflamed tissue (31-32 fragments) than in grade 4 (34-41 fragments). N-Terminal fragments (DYN 1-15, 1-11, 1-10, and 1-6) were metabolized slower at pH 5.5 as compared to pH 7.4. DYN 1-12, 1-8, 2-10, 4-10, 5-10, and 8-14 were only observed under the inflammatory pH while DYN 5-17 and 6-17 were only identified upon incubation with grade 4 CRSwNP tissues. DYN 1-17 metabolism was significantly affected by the pH level and the severity of the inflammation of CRSwNP tissues, indicating the potential roles of DYN 1-17 and its fragments in modulating the inflammatory response and their avenue as therapeutics in future studies.

Characteristics of mucin hypersecretion in different inflammatory patterns based on endotypes of chronic rhinosinusitis. Clin Transl Allergy 2024; 14:e12334. [PMID: 38282195 PMCID: PMC10802810 DOI: 10.1002/clt2.12334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 12/14/2023] [Accepted: 12/21/2023] [Indexed: 01/30/2024] Open
Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is usually accompanied by mucin hypersecretion that can lead to mucus accumulation and impair nasal mucociliary clearance, thus exacerbating airway inflammation. Abnormal mucin hypersecretion is regulated by different T helper (Th) cytokines, which are associated with different endotype-driven inflammatory responses. Therefore, it is of great significance to understand how these factors regulate mucin hypersecretion to provide precise treatment strategies for different endotypes of CRS. BODY: Thus far, the most common endotypes of CRS are classified as type 1, type 2, or type 3 immune responses based on innate and adaptive cell-mediated effector immunity, and the representative Th cytokines in these immune responses, such as IFN-γ, TNF-α, IL-4, IL-5, IL-13, IL-10, IL-17, and IL-22, play an important regulatory role in mucin secretion. We reviewed all the related literature in the PubMed database to determine the expression of these Th cytokines in CRS and the role they play in the regulation of mucin secretion. CONCLUSION We believe that the main Th cytokines involved in specific endotypes of CRS play a key role in regulating abnormal mucin secretion, which contributes to better understanding of the pathogenesis of CRS and provides therapeutic targets for airway inflammatory diseases associated with mucin hypersecretion.

Abstract
Recently, significant progress has been made in identifying the cellular and molecular mechanisms responsible for the pathogenesis of chronic rhinosinusitis (CRS). Cohort studies of CRS have led to advances in the clinical understanding of this disease. New therapeutic agents have been approved or are undergoing clinical trials to expand treatment options for this disease. One of the promising areas in medicine is the provision of personalized clinical care. From this perspective, CRS can be divided into three different endotypes depending on the type of underlying inflammatory response. In the United States, CRS with and without nasal polyps is predominantly characterized as the second inflammatory endotype. CRS with nasal polyps (about 17%) and without nasal polyps (up to 20%) belongs to the 1st and 3rd inflammatory endotypes, respectively. And if for the second inflammatory endotype the effectiveness of targeted biological therapy is beyond doubt, then for the first and third inflammatory endotypes the principles of such conservative therapy are under active development. Moreover, large validated studies to confirm associations between CRS phenotypes and endotypes, as well as to find effective biological markers of inflammatory endotypes, remain to be performed.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common chronic inflammatory disease of the nasal cavity and paranasal sinuses. The role of neutrophils in the pathogenesis of CRSwNP has attracted more attention in recent years, due to its association with more severe disease and reduced steroid responsiveness. Lipocalin-2 (LCN2) has been found to modulate neutrophils infiltration in other neutrophilic inflammation including inflammatory bowel disease, rheumatoid arthritis, and psoriasis. The aim was to evaluate the expression and regulator role of LCN2 in neutrophilic inflammation in CRSwNP, and its role as a potential biomarker predicting non-eosinophilic CRSwNP (neCRSwNP). METHODS Bioinformatic analysis, immunostainings, real-time PCR and ELISA were used to analyze the expression and location of LCN2 in nasal tissues. The expression of proinflammatory mediators were assessed in nasal tissues and secretions. LCN2 production in human nasal epithelial cells (HNECs) and neutrophils, as well as its role in neutrophilic inflammation was evaluated by in vitro experiments. RESULTS LCN2 was mainly located in neutrophils and HNECs of nasal polyps. LCN2 expression was also significantly higher in the polyp tissue and nasal secretions from patients with neCRSwNP. The LCN2 levels were positively correlated with type 3 inflammation markers, including G-CSF, IL-8, and IL-17. LCN2 expression could be upregulated by IL-17 A and TNF-α in HNECs, and LCN2 could also promote the expression of IL-8 in dispersed polyp cells and HNECs. CONCLUSIONS LCN2 could serve as a novel biomarker predicting patients with neCRSwNP, and the increased expression of LCN2 may participate in the pathogenesis of neCRSwNP.

Abstract
OBJECTIVE Chronic rhinosinusitis with nasal polyp (CRSwNP) is one of the major phenotypes of chronic rhinosinusitis (CRS) with a high symptom burden. Doxycycline can be used as add-on therapy in CRSwNP. We aimed to evaluate short-term efficacy of oral doxycycline on visual analog scale (VAS) and SNOT-22 (Sino-nasal outcome test) score for CRSwNP. METHODS Visual analog score (VAS) for nasal symptoms and total SNOT-22 scores of 28 patients who applied with the diagnosis of CRSwNP and received 100 mg doxycycline for 21 days were analyzed in this retrospective cohort study. Doxycycline efficacy was also evaluated in subgroups determined according to asthma, presence of atopy, total IgE and eosinophil levels. RESULTS After 21-day doxycycline treatment, there was a significant improvement in VAS score for post-nasal drip, nasal discharge, nasal congestion, and sneeze, and total SNOT-22 score (p = 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001, respectively). No significant improvement was observed in VAS score for the loss of smell (p = 0.18). In the asthmatic subgroup, there were significant improvements in all VAS scores and total SNOT-22 score after doxycycline. In the non-asthmatic subgroup, there was no significant change in any of the VAS scores, but total SNOT-22 score was significantly improved (42 [21-78] vs. 18 [9-33]; p = 0.043). Improvement in VAS score for loss of smell is significant in only some subgroups like asthmatic patients, non-atopic patients, and patients with eosinophil >300 cell/µL. CONCLUSIONS Doxycycline can be considered as an add-on treatment for symptom control in patients especially with CRSwNP comorbid with asthma.

Abstract
Chronic rhinosinusitis with nasal polyposis (CRSwNP) is an inflammatory disease of the nasal and sinus mucosa. This inflammatory process is supported by a multitude of cytokines, including IL-4, IL-5, and IL-13 produced by Th2 cells, as well as by IgE produced by B lymphocytes in response to a stimulus. Omalizumab is an anti-IgE monoclonal antibody with well-recognized roles in allergic asthma and chronic spontaneous urticaria. The aim of this study was to evaluate the clinical efficacy of omalizumab in a cohort of 13 patients suffering from chronic rhinosinusitis with CRSwNP. The inclusion criteria considered were as follows: 18 years of age, with a diagnosis of chronic rhinosinusitis with severe nasal polyposis expressed by an NPS greater than or equal to 5 and/or a SNOT-22 greater than or equal to 50. In addition, in the enrolled patients, the classic treatment with corticosteroids had to have been suspended due to recurrence after surgery or lack of response. Our results highlighted that omalizumab treatment for 16 weeks improved the parameters analyzed: SNOT-22, NPS, NRS, and NCS. The clinical efficacy of omalizumab was further strengthened by a significant improvement in respiratory function as well as reductions in the nasal polyps' size and in the associated symptoms.

Oncostatin M's Involvement in the Pathogenesis of Chronic Rhinosinusitis: Focus on Type 1 and 2 Inflammation. Biomedicines 2023; 11:3224. [PMID: 38137445 PMCID: PMC10740885 DOI: 10.3390/biomedicines11123224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 11/27/2023] [Accepted: 12/04/2023] [Indexed: 12/24/2023] Open
Abstract
OBJECTIVES The cytokine oncostatin M (OSM) elicits pathogenic effects involving disruption of the epithelial barrier function as a part of immunological response networks. It is unclear how these integrated cytokine signals influence inflammation and other physiological processes in the pathology of chronic rhinosinusitis (CRS). We investigated the expression and distribution of OSM and OSM receptor (OSMR) in CRS patients' sinonasal specimens, and we compared the results with a panel of inflammatory cytokine levels and clinical features. PATIENTS AND METHODS We classified CRS patients as eosinophilic (ECRS, n = 36) or non-eosinophilic (non-ECRS, n = 35) based on the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis phenotypic criteria and compared their cases with those of 20 control subjects. We also examined OSM's stimulatory effects on cytokine receptor expression levels using the human bronchial epithelium cell line BEAS-2B. RESULTS RT-PCR showed that the OSM mRNA levels were significantly increased in the CRS patients' ethmoid sinus mucosa. The OSM mRNA levels were positively correlated with those of TNF-α, IL-1β, IL-13, and OSMR-β. In BEAS-2B cells, OSM treatment induced significant increases in the OSMRβ, IL-1R1, and IL-13Ra mRNA levels. CONCLUSIONS OSM is involved in the pathogenesis of CRS in both type 1 and type 2 inflammation, suggesting the OSM signaling pathway as a potential therapeutic target for modulating epithelial stromal interactions.

Abstract
Chronic rhinosinusitis (CRS) is a highly heterogeneous disease characterized by inflammation in the nasal and sinus mucosa. The CRS phenotypes, based on the presence or absence of nasal polyps, are known as CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). However, this classification has limitations in fully capturing the mechanisms and clinical manifestations of CRS. To address the heterogeneity of CRS, there has been a growing focus on classifying the condition into distinct endotypes. Endotype classification involves grouping patients based on specific molecular, immunological, and clinical characteristics, allowing for more personalized and targeted treatment approaches.This review delves into the current state of endotype classifications for CRS. It explores the role of geographic factors, microbiome, and subphenotype in shaping different endotypes. Additionally, the review examines how various clinical features are associated with specific endotypes, providing valuable insights into tailoring treatment options for better outcomes and transitions between different endotypes.Overall, this review offers a comprehensive and up-to-date perspective on the intricate realm of CRS endotype classifications. By unraveling the molecular and clinical intricacies, this review lays the foundation for more precise, effective, and individualized treatment strategies in the management of CRS.

Utilization of Transcriptomic Profiling to Identify Molecular Markers Predicting Successful Recovery Following Endoscopic Sinus Surgery for Chronic Rhinosinusitis. Otolaryngol Head Neck Surg 2023; 169:1662-1673.

Abstract
OBJECTIVES Successful recovery from chronic rhinosinusitis (CRS) following endoscopic sinus surgery (ESS) can be characterized by minimal presence of symptoms and absence of disease on endoscopy. However, molecular markers of surgical success remain to be characterized. These could allow for better tailoring of perioperative therapy. This study aims to identify novel molecular markers associated with surgery responsive patient. STUDY DESIGN Prospective cohort study. SETTING Single academic hospital center. METHOD One hundred eighteen consecutive patients with CRS at high risk of recurrence after surgery were followed prospectively following ESS in an academic medical center. Symptomatic and endoscopic outcomes were assessed at 4 months, with success rigorously defined subjectively as minimal or no symptoms (no symptom greater than 1 on an ordinal scale of 0-3) and objectively by the absence of nasal polyposis on sinus cavity endoscopy and Lund-Kennedy endoscopic edema score no greater than 1. Samples were obtained at the time of surgery and at 4-month postoperatively. Changes associated with surgery were determined by gene expression profiling using Affymetrix's Clariom S Human HT arrays. RESULTS Successful ESS was characterized by a mild upregulation in Type 1 inflammation, upregulation of cell cycle progression, and epithelial barrier and proliferation-associated genes and pathways. ESS failure was associated to very high levels of Type 1 inflammation along with downregulation of epithelial barrier function and regeneration genes and pathways. CONCLUSION Successful recovery from ESS involves restoration of epithelial function and regulated activation of Type 1 inflammation. Excessively elevated Type 1 inflammation is associated with epithelial barrier dysfunction.

Abstract
Chronic rhinosinusitis (CRS) is an important ENT pathology which affects about 5-12% of the general population. The treatment of CRS can be pharmacological (nasal sprays, douches, systemic antibiotics and steroids), surgical (endoscopic sinus surgery) or immunological according to established algorithms. CRS was divided for many years into CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). New ways of classifying CRS by endotypes (presence of neutrophilia, eosinophilia, fibrosis, glandular hypertrophy and epithelial dysmorphisms) appeared after the most recent understandings of the pathophysiology of the disease. Other classifications divide CRS into primary and secondary forms, localized/diffuse types and anatomical presentation. A new type of treatment has been administered in the last years, biologics. For the moment, biologics are indicated just in the cases of the patients who have undergone ESS or have contraindications for surgery and have bilateral polyps and meet a minimum of three of the following criteria: the necessity for systemic therapies with oral or parenteral corticosteroids or contraindications to systemic steroids, significant loss of smell or impaired QoL score, comorbid asthma and type 2 inflammation. This article aims to present the most relevant studies which used the three types of biologics (anti-IgE, anti-IL5 and anti-IL4/IL3) and wishes to increase the awareness of this new type of treatment that can be used in some CRS cases.

Abstract
The exponential growth of precision diagnostic tools, including omic technologies, molecular diagnostics, sophisticated genetic and epigenetic editing, imaging and nano-technologies and patient access to extensive health care, has resulted in vast amounts of unbiased data enabling in-depth disease characterization. New disease endotypes have been identified for various allergic diseases and triggered the gradual transition from a disease description focused on symptoms to identifying biomarkers and intricate pathogenetic and metabolic pathways. Consequently, the current disease taxonomy has to be revised for better categorization. This European Academy of Allergy and Clinical Immunology Position Paper responds to this challenge and provides a modern nomenclature for allergic diseases, which respects the earlier classifications back to the early 20th century. Hypersensitivity reactions originally described by Gell and Coombs have been extended into nine different types comprising antibody- (I-III), cell-mediated (IVa-c), tissue-driven mechanisms (V-VI) and direct response to chemicals (VII). Types I-III are linked to classical and newly described clinical conditions. Type IVa-c are specified and detailed according to the current understanding of T1, T2 and T3 responses. Types V-VI involve epithelial barrier defects and metabolic-induced immune dysregulation, while direct cellular and inflammatory responses to chemicals are covered in type VII. It is notable that several combinations of mixed types may appear in the clinical setting. The clinical relevance of the current approach for allergy practice will be conferred in another article that will follow this year, aiming at showing the relevance in clinical practice where various endotypes can overlap and evolve over the lifetime.
