Inflammatory Profile of Chronic Rhinosinusitis With Nasal Polyp Patients in Brazil: Multicenter Study. Otolaryngol Head Neck Surg 2024. [PMID: 39087780 DOI: 10.1002/ohn.904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 05/22/2024] [Accepted: 06/22/2024] [Indexed: 08/02/2024]
Abstract
OBJECTIVES To determine the inflammatory profile of CRSwNP in Brazil and characterize the subgroups of CRSwNP patients in this population through cluster analysis. STUDY DESIGN Multicenter cross-sectional study involving 15 centers representing different regions of Brazil. SUBJECTS AND METHODS Clinical data of 166 patients and 80 controls, aged 18 to 70 years old, number of surgeries for CRS, history of asthma and aspirin sensitivity, and Lund-Mackay scores on CT scans. During nasal endoscopy, we obtained the Lund-Kennedy scores and collected 2 samples of nasal polyps: one for eosinophil and neutrophil tissue counts and one to quantify different cytokines. RESULTS 79.6% of our patients had 10 or more eosinophils/HPF. CRSwNP groups exhibited significantly lower concentrations of TNF-alpha and significantly higher concentrations of IFN-gamma, CCL11/Eotaxin, CCL24/Eotaxin-2/MPIF-2, and CCL26/Eotaxin-3 versus the control group (Kruskal-Wallis test). Comparison between CRSwNP groups (≥10 vs <10 eosinophils/HPF) showed no difference in cytokine concentration (Mann-Whitney test). Hierarchical clustering and PCA according to cytokine concentrations revealed 2 main Clusters, with a significantly higher concentration of all cytokines in Cluster 1 (n = 35) than in Cluster 2 (n = 121), except IL-6 and IL-33 (Mann-Whitney test). According to ROC curve analysis the best cut-off to differentiate the 2 clusters was 43 eosinophils/HPF. The group with ≥43 presented a higher prevalence of men and a higher Lund-Mackay score (Mann-Whitney test). CONCLUSIONS CRSwNP patients in Brazil present mixed inflammation, with 2 distinct groups (high and low inflammatory pattern) that can be distinguished by tissue eosinophilia of ≥43 eosinophils/HPF cut-off in nasal polyps.

Abstract
Rhinology, allergy, and skull base surgery are fields primed for the integration and implementation of artificial intelligence (AI). The heterogeneity of the disease processes within these fields highlights the opportunity for AI to augment clinical care and promote personalized medicine. Numerous research studies have been published demonstrating the development and clinical potential of AI models within the field. Most describe in silico evaluation models without direct clinical implementation. The major themes of existing studies include diagnostic or clinical decisions support, clustering patients into specific phenotypes or endotypes, predicting post-treatment outcomes, and surgical planning.

Abstract
OBJECTIVE To provide a comprehensive overview on the applications of artificial intelligence (AI) in rhinology, highlight its limitations, and propose strategies for its integration into surgical practice. DATA SOURCES Medline, Embase, CENTRAL, Ei Compendex, IEEE, and Web of Science. REVIEW METHODS English studies from inception until January 2022 and those focusing on any application of AI in rhinology were included. Study selection was independently performed by 2 authors; discrepancies were resolved by the senior author. Studies were categorized by rhinology theme, and data collection comprised type of AI utilized, sample size, and outcomes, including accuracy and precision among others. CONCLUSIONS An overall 5435 articles were identified. Following abstract and title screening, 130 articles underwent full-text review, and 59 articles were selected for analysis. Eleven studies were from the gray literature. Articles were stratified into image processing, segmentation, and diagnostics (n = 27); rhinosinusitis classification (n = 14); treatment and disease outcome prediction (n = 8); optimizing surgical navigation and phase assessment (n = 3); robotic surgery (n = 2); olfactory dysfunction (n = 2); and diagnosis of allergic rhinitis (n = 3). Most AI studies were published from 2016 onward (n = 45). IMPLICATIONS FOR PRACTICE This state of the art review aimed to highlight the increasing applications of AI in rhinology. Next steps will entail multidisciplinary collaboration to ensure data integrity, ongoing validation of AI algorithms, and integration into clinical practice. Future research should be tailored at the interplay of AI with robotics and surgical education.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) is a heterogeneous disease with a variety of cellular and molecular pathophysiologic mechanisms. Biomarkers have been explored in CRS using various phenotypes, such as polyp recurrence after surgery. Recently, the presence of regiotype in CRS with nasal polyps (CRSwNP) and the introduction of biologics for the treatment of CRSwNP has indicated the importance of endotypes, and there is a need to elucidate endotype-based biomarkers. AREAS COVERED Biomarkers for eosinophilic CRS, nasal polyps, disease severity, and polyp recurrence have been identified. Additionally, endotypes are being identified for CRSwNP and CRS without nasal polyps using cluster analysis, an unsupervised learning technique. EXPERT OPINION Endotypes in CRS have still being established, and biomarkers capable of identifying endotypes of CRS are not yet clear. When identifying endotype-based biomarkers, it is necessary to first identify endotypes clarified by cluster analysis for outcomes. With the application of machine learning, the idea of predicting outcomes using a combination of multiple integrated biomarkers, rather than a single biomarker, will become mainstream.

Abstract
BACKGROUND While various sinus computed tomography (CT) scoring systems have been proposed and used in the literature, no single system has been identified as superior. The strength of associations between CT scoring systems and measures of olfaction also remains unclear. METHODS A systematic review of PubMed, CINAHL, Scopus, and the Cochrane Library was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported both CT scores and measures of olfaction in a cross-sectional manner were included. RESULTS A total of 37 studies were eligible for meta-analysis. Of 8035 patients with chronic rhinosinusitis, 55.6% were male patients and 53.2% had chronic rhinosinusitis with nasal polyps. Analysis by meta-regression was performed of Lund-Mackay (LM) versus Smell Identification Test-40 (SIT-40; 12 studies), Brief Smell Identification Test (BSIT; 10 studies), Sniffin' Sticks (SS; 10 studies), and Toyota & Takagi (T&T) olfactometry (four studies). A significant moderate association was found between LM and SIT-40 (R2 = 0.612, p < 0.001) and LM and SS (R2 = 0.612, p < 0.001). An association between LM and BSIT approached significance (R2 = 0.461, p = 0.054). No significant associations were noted between LM and T&T olfactometry and between LM and SS when stratified by nasal polyp status. CONCLUSION There is a significant moderate association of current CT scoring systems to SIT-40 and SS. Further research should focus on associations of objective measures of olfaction to CT scores of the nasal cavity, sinuses, and olfactory cleft, as well as other disease markers.

Abstract
BACKGROUND Endoscopic sinus surgery (ESS) offers excellent outcomes for patients with chronic rhinosinusitis (CRS) in the general population. It is unclear whether older patients with significant medical comorbidities experience similar benefits. OBJECTIVE The purpose of this study is to evaluate whether increasing medical comorbidity is associated with worse sinonasal quality of life outcomes after ESS in older patients. METHODS This is a retrospective study of CRS patients 55 years or older who underwent elective ESS at an academic institution from July 2017 to June 2019. 22-Item Sino-Nasal Outcomes Test (SNOT-22) scores were gathered at baseline as well as at 3 and 6 months following surgery. Data on demographics, medical comorbidities, preoperative Lund-Mackay (LM) scores, and postoperative complications were extracted from the medical record. The Charlson Comorbidity Index (CCI) was calculated for each patient. Multivariate linear regression was used to evaluate a potential association between CCI and change in SNOT-22 scores at 3 months postoperatively. RESULTS A total of 205 patients met inclusion criteria with a mean (SD) CCI score of 2 (2.4) and a CCI score range of 0 to 11. The mean (SD) LM score was 8 (5.3). Rates of asthma and nasal polyposis were 28.3% and 36.6%, respectively. The mean (SD) improvement in SNOT-22 scores at 3 and 6 months compared to baseline was 17.9 (19.7) and 20.9 (18.1) points, respectively. After adjusting for covariates, there was no significant association between CCI and change in SNOT-22 scores. CONCLUSION Greater medical comorbidity is not associated with worse SNOT-22 outcomes postoperatively, although future studies are needed to determine if comorbidities are associated with higher complication rates. A multidisciplinary approach to perioperative care is critical in maintaining the safety and efficacy of ESS in this patient population.

Abstract
Chronic rhinosinusitis (CRS) is characterized by persistent locoregional mucosal inflammation of the paranasal sinuses and upper airway that has substantial associated health care costs1. Personalized approaches to care that incorporate use of molecular biomarkers, phenotypes and inflammatory endotypes is a major focus of research at this time, and the concurrent rise of targeted therapeutics and biologic therapies has the potential to rapidly advance care and improve outcomes. Recent findings suggest that improved understanding of CRS phenotypic and endotypic heterogeneity, and incorporation of these characteristics into clinical care pathways, may facilitate more effective selection of surgical and/or therapeutic interventions2. Ultimately, these personalized approaches have the potential to target specific inflammatory pathways, increase efficacy, reduce costs, and limit side effects. This review summarizes recent advances in the identification and characterization of CRS phenotypes, endotypes, and biomarkers and reviews potential implications for targeted therapeutics.

Abstract
Objectives: Chronic rhinosinusitis (CRS) is a common and costly health problem in the United States. While often associated with younger adults, CRS can affect the elderly. As the aging population increases in the United States, the cost burden of CRS in older adults is important to assess. The objective of this study is to characterize healthcare resource utilization (HCRU) and healthcare expenditure (HCE) for CRS in this population. Methods: Patients meeting criteria for CRS with three years of continuous data were identified on IBM® Marketscan Research Databases over a five-year period (2013–2017). Medication utilization, outpatient visits, surgery, and expenditures related to CRS were assessed for older adults (>65) and compared with other age groups. As a secondary analysis, multivariable generalized linear models were utilized to compare HCE while adjusting for baseline medication utilization. Results: A total of 238,825 patients met the inclusion criteria, of which 20,927 were older adults. Older adults had the highest overall prevalence of nasal polyps (10%) and asthma (16%) among adult groups. Surgery rate was lower than other adult groups, but medication utilization was the highest. Mean overall HCE at two years was highest in older adults (USD 2545 vs. 2298 in young adults). However, HCE was highest for the young adult group after adjusting for baseline medication usage. Conclusion: Older adults had a higher rate of CRS-related co-morbidities as well as the highest CRS-related medication utilization and unadjusted two-year HCE. Although the reasons for this are unclear, possibilities include greater disease severity and preference for medical versus surgical management. HCE for CRS is expected to increase as the aging population grows.

Artificial intelligence for cellular phenotyping diagnosis of nasal polyps by whole-slide imaging. EBioMedicine 2021; 66:103336. [PMID: 33857906 PMCID: PMC8050855 DOI: 10.1016/j.ebiom.2021.103336] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 03/12/2021] [Accepted: 03/24/2021] [Indexed: 11/11/2022] Open
Abstract
Background artificial intelligence (AI) for cellular phenotyping diagnosis of nasal polyps by whole-slide imaging (WSI) is lacking. We aim to establish an AI chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0) to obtain the proportion of inflammatory cells for cellular phenotyping diagnosis of nasal polyps and to explore the clinical significance of different phenotypes of nasal polyps on the WSI. Methods a total of 453 patients were enrolled in our study. For the development of AICEP 2.0, 179 patients (WSIs) were obtained from the Third Affiliated Hospital of Sun Yat-Sen University (3HSYSU) from January 2008 to December 2018. A total of 24,625 patches were automatically extracted from the regions of interest under a 400× HPF by Openslide and the number of inflammatory cells in these patches was counted by two pathologists. For the application of AICEP 2.0 in a prospective cohort, 158 patients aged 14–70 years old with chronic rhinosinusitis with nasal polyps (CRSwNP) who had undergone endoscopic sinus surgery at 3HSYSU from June 2020 to December 2020 were included for preoperative demographic characteristics. For the application of AICEP 2.0 in a retrospective cohort, 116 patients with CRSwNP who had undergone endoscopic sinus surgery from May 2016 to June 2017 were enrolled for the recurrence rate. The proportion of inflammatory cells of these patients on WSI was calculated by our AICEP 2.0. Findings for AICEP 2.0, the mean absolute errors of the ratios of eosinophils, lymphocytes, neutrophils, and plasma cells were 1.64%, 2.13%, 1.06%, and 1.22%, respectively. The four phenotypes of nasal polyps were significantly different in clinical characteristics (including asthma, itching, sneezing, total IgE, peripheral eosinophils%, tissue eosinophils%, tissue neutrophils%, tissue lymphocytes%, tissue plasma cells%, and recurrence rate; P <0.05), but there were no significant differences in age distribution, onset time, total VAS score, Lund-Kennedy score, or Lund-Mackay score. The percentage of peripheral eosinophils was positively correlated with the percentage of tissue eosinophils (r = 0.560, P <0.001) and negatively correlated with tissue lymphocytes% (r = -0.489, P <0.001), tissue neutrophils% (r = -0.225, P = 0.005), and tissue plasma cells% (r = -0.266, P = 0.001) in WSIs.

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 Rhinologic disease can be responsible for systemic symptoms affecting mood, cognition, and sleep. It is unclear whether sleep disturbance in specific rhinologic disorders (chronic rhinosinusitis [CRS], rhinitis, and nasal septal deviation [NSD]) is an obstructive phenomenon or due to other mechanisms. In this review we examine the impact of CRS, rhinitis, and NSD on objective and subjective sleep outcome metrics and draw comparisons to normal controls and patients with known obstructive sleep apnea (OSA). METHODS A systematic review of 4 databases (PubMed, Scopus, Cochrane Library, and Web of Science) was performed. Studies reporting on objective (apnea-hypopnea index [AHI], respiratory disturbance index [RDI], oxygen nadir) and subjective (Epworth Sleepiness Scale [EpSS], Pittsburgh Sleep Quality Index [PSQI], Fatigue Severity Scale [FSS]) sleep parameters and disease-specific patient-reported outcome measures (PROMs; 22-item Sino-Nasal Outcome Test [SNOT-22], Rhinoconjunctivitis Quality of Life Questionnaire [RQLQ], Nasal Obstruction Symptom Evaluation [NOSE]) were included. RESULTS The database search yielded 1414 unique articles, of which 103 were included for analysis. Baseline PROMs were at the high end of normal to abnormal for all 3 conditions: EpSS: CRS (9.8 ± 4.0), rhinitis (9.7 ± 4.3), and NSD (8.9 ± 4.6); and PSQI: CRS (11.0 ± 4.5), rhinitis (6.1 ± 3.7), and NSD (8.6 ± 3.5). Objective measures demonstrated a mild to moderate OSA in the studied diseases: AHI: CRS (10.4 ± 11.5), rhinitis (8.6 ± 8.8), and NSD (13.0 ± 6.9). There were significant differences when compared with reported norms in all measured outcomes (p < 0.001). CONCLUSION Sleep quality is impacted by rhinologic (CRS, rhinitis, NSD) disease. There is likely a mild obstructive component contributing to poor sleep, but other contributing factors may be involved.

Multiomic analysis identifies natural intrapatient temporal variability and changes in response to systemic corticosteroid therapy in chronic rhinosinusitis.

Abstract
INTRODUCTION The pathophysiology and temporal dynamics of affected tissues in chronic rhinosinusitis (CRS) remain poorly understood. Here, we present a multiomics-based time-series assessment of nasal polyp biopsies from three patients with CRS, assessing natural variability over time and local response to systemic corticosteroid therapy. METHODS Polyp tissue biopsies were collected at three time points over two consecutive weeks. Patients were prescribed prednisone (30 mg daily) for 1 week between Collections 2 and 3. Polyp transcriptome, proteome, and microbiota were assessed via RNAseq, SWATH mass spectrometry, and 16S ribosomal RNA and ITS2 amplicon sequencing. Baseline interpatient variability, natural intrapatient variability over time, and local response to systemic corticosteroids, were investigated. RESULTS Overall, the highly abundant transcripts and proteins were associated with pathways involved in inflammation, FAS, cadherin, integrin, Wnt, apoptosis, and cytoskeletal signaling, as well as coagulation and B- and T-cell activation. Transcripts and proteins that naturally varied over time included those involved with inflammation- and epithelial-mesenchymal transition-related pathways, and a number of common candidate target biomarkers of CRS. Ten transcripts responded significantly to corticosteroid therapy, including downregulation of TNF, CCL20, and GSDMA, and upregulation of OVGP1, and PCDHGB1. Members of the bacterial genus Streptococcus positively correlated with immunoglobulin proteins IGKC and IGHG1. CONCLUSIONS Understanding natural dynamics of CRS-associated tissues is essential to provide baseline context for all studies on putative biomarkers, mechanisms, and subtypes of CRS. These data further our understanding of the natural dynamics within nasal polypoid tissue, as well as local changes in response to systemic corticosteroid therapy.

Abstract
This study presents an up-to-date survey of the use of artificial intelligence (AI) in the field of otorhinolaryngology, considering opportunities, research challenges, and research directions. We searched PubMed, the Cochrane Central Register of Controlled Trials, Embase, and the Web of Science. We initially retrieved 458 articles. The exclusion of non-English publications and duplicates yielded a total of 90 remaining studies. These 90 studies were divided into those analyzing medical images, voice, medical devices, and clinical diagnoses and treatments. Most studies (42.2%, 38/90) used AI for image-based analysis, followed by clinical diagnoses and treatments (24 studies). Each of the remaining two subcategories included 14 studies. Machine learning and deep learning have been extensively applied in the field of otorhinolaryngology. However, the performance of AI models varies and research challenges remain.

Abstract
BACKGROUND An important challenge of big data is using complex information networks to provide useful clinical information. Recently, machine learning, and particularly deep learning, has enabled rapid advances in clinical practice. The application of artificial intelligence (AI) and machine learning (ML) in rhinology is an increasingly relevant topic. PURPOSE We review the literature and provide a detailed overview of the recent advances in AI and ML as applied to rhinology. Also, we discuss both the significant benefits of this work as well as the challenges in the implementation and acceptance of these methods for clinical purposes. METHODS We aimed to identify and explain published studies on the use of AI and ML in rhinology based on PubMed, Scopus, and Google searches. The search string "nasal OR respiratory AND artificial intelligence OR machine learning" was used. Most of the studies covered areas of paranasal sinuses radiology, including allergic rhinitis, chronic rhinitis, computed tomography scans, and nasal cytology. RESULTS Cluster analysis and convolutional neural networks (CNNs) were mainly used in studies related to rhinology. AI is increasingly affecting healthcare research, and ML technology has been used in studies of chronic rhinitis and allergic rhinitis, providing some exciting new research modalities. CONCLUSION AI is especially useful when there is no conclusive evidence to aid decision making. ML can help doctors make clinical decisions, but it does not entirely replace doctors. However, when critically evaluating studies using this technique, rhinologists must take into account the limitations of its applications and use.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a spectrum of complex inflammatory conditions of the sinonasal mucosa. Identification of biomarkers that enable classification and improved delineation among CRS endotypes is of increasing interest. However, the extent to which less invasive sampling methods identify genuine tissue inflammatory patterns is not well understood. The aim of this study was to investigate mucosal swab and cytobrush sampling as less invasive proxies for tissue transcription levels of putative biomarkers of CRS. METHODS Expression levels of 21 biomarkers of interest were assessed via custom TaqMan array cards from mucosal biopsy, cytobrush, and swab samples, in 32 patients with CRS. Reported expression levels were compared between each of the 3 sample types within each patient. RESULTS Reported transcription levels from swab samples for IL33, MUC5AC, IL1RN, CXCL8 (IL-8), TNF, IFNG, IL5, OSM, IL1A, and IL17C, and cytobrush levels for IL33, MUC5AC, IL5RA, IL1RN, CXCL8 (IL-8), and IL5 were significantly different to tissue levels from matched biopsy samples. CONCLUSION Reported expression via swab and cytobrush sampling differed from patterns observed in matched tissue for 10 of 21 and 6 of 21 markers, respectively. Non-biopsy-based studies for these particular markers may therefore not adequately represent tissue inflammatory processes and should be interpreted with caution. Cytobrush samples largely tracked tissue patterns for the remaining target biomarkers. In these cases, cytobrush sampling appears to adequately reflect tissue patterns for several putative biomarkers of CRS, supporting their use in clinical and research settings as a less-invasive proxy for the assessment of mucosal tissue inflammatory transcription patterns.

Abstract
BACKGROUND Common rhinologic diagnoses have similar presentations with a varying degree of overlap. Patterns may exist within clinical data that can be useful for early diagnosis and predicting outcomes. OBJECTIVE To explore the feasibility of artificial intelligence to differentiate patterns in patient data in order to develop clinically-meaningful diagnostic groups. METHODS A cross-sectional study of prospectively-acquired patient data at a tertiary rhinology clinic was performed. Data extracted included objective findings on nasal endoscopy, patient reported quality of life (PRQOL) instrument ratings, peripheral eosinophil fraction, and past medical history. Unsupervised non-hierarchical cluster analysis was performed to discover patterns in the data using 22 input variables. RESULTS A total of 545 patients were analyzed after application of inclusion and exclusion criteria yielding 7 unique patient clusters, highly dependent on PRQOL scores and demographics. The clusters were clinically-relevant with distinct characteristics. Chronic rhinosinusitis without nasal polyposis (CRSsNP) was associated with two clusters having low frequencies of asthma and low eosinophil fractions. Chronic rhinosinusitis with nasal polyposis (CRSwNP) was associated with high frequency of asthma, mean (standard deviation [SD]) NOSE scores of 66 (19) and SNOT-22 scores of 41 (15), and high eosinophil fractions. AR was present in multiple clusters. RARS was associated with the youngest population with mean (SD) NOSE score of 54 (23) and SNOT-22 score of 41 (19). CONCLUSION Broader consideration of initially available clinical data may improve diagnostic efficiency for rhinologic conditions without ancillary studies, using computer-driven algorithms. PRQOL scores and demographic information appeared to be useful adjuncts, with associations to diagnoses in this pilot study.

Abstract
BACKGROUND Patients with chronic rhinosinusitis (CRS) commonly experience both reduced quality of life (QOL) and olfactory dysfunction (OD). Literature on the impacts of appropriate medical therapy (AMT) for CRS on QOL and OD is limited, and the focused design of these studies may limit their applicability to usual clinical practice. METHODS Adults with symptomatic CRS were prospectively enrolled (November 2016 to October 2018) into an observational, multi-institutional study. Individualized AMT was initiated using standard practice according to evidence-based guidelines. Endoscopy examination (Lund-Kennedy), olfactory function (Sniffin' Sticks) testing, and QOL survey responses (22-item Sino-Nasal Outcome Test [SNOT-22], Questionnaire of Olfactory Disorders-Negative Statements [QOD-NS]) were obtained at enrollment and follow-up. RESULTS Baseline measures demonstrated heterogeneity of QOL and OD. After an average of 7.8 weeks, within-subject median SNOT-22 total improved by 39.5% (n = 39, p < 0.001) relative to baseline, including 50% (p = 0.014) improvement for item #21, "Sense of smell/taste." QOD-NS improvement was also statistically significant (p = 0.044). Sniffin' Sticks score relative improvement of 10.9% (n = 33, p = 0.109) was not statistically significant and lacked correlation with SNOT-22 total scores (R = -0.247, p = 0.165) or QOD-NS total scores (R = -0.016, p = 0.930), but correlated moderately with endoscopy score (R = -0.436, p = 0.018). CONCLUSIONS Participants with varied impacts of CRS, treated with individualized short-term AMT, demonstrated significant improvements in CRS- and olfactory-specific QOL measures, without corresponding improvement in clinically measured olfactory function. Olfactory function changes moderately correlated with endoscopy score changes, but lacked an association with QOL measurements.

Abstract
The term chronic rhinosinusitis (CRS) comprises of an assortment of diseases that share a common feature: inflammation of the sinonasal mucosa. The phenotype classification of CRS, based on the presence of polyps, has failed to offer a curative treatment for the disease, particularly in refractory cases. Chronic rhinosinusitis with nasal polyps (CRSwNP) remains a challenging entity. Researchers have made efforts trying to characterize subtypes of the disease according to the endotypes, which are delineated by different immunological pathways, using biomarkers. Even if the inflammatory processes controlling CRSwNP are not fully understood, data suggested that the disease associated with a type 2 inflammatory mechanisms can be also linked to the type 1 or type 3 pathomechanism, being highly heterogeneous. Biomarkers for CRSwNP are proposed, such as: eosinophil count, cytokines, metalloproteinases, bitter and sweet taste receptors, and the nasal microbiome. For endotyping to be clinically applicable and simply determined, biomarkers referring to the intrinsic biomolecular mechanism still need to be found. Precision medicine is becoming the new standard of care, but innovative therapies such as biologics may be rather challenging for the clinicians in their daily practice. This new approach to CRSwNP implies patient selection and a simple algorithm for deciding the right treatment, easy to implement and adjust. Our review points out the ongoing new research on the pathophysiology of CRSwNP, biomarkers and treatment opportunities. It allows clinicians to keep abreast of current evidence-based knowledge and to individualize the management of CRSwNP, especially in refractory cases.

Abstract
Our understanding of the pathophysiology of chronic rhinosinusitis (CRS) is continuously evolving. The traditional description of CRS in terms of two phenotypes based on the presence or absence of nasal polyps belies the underlying intricate immunopathophysiological processes responsible for this condition. CRS is being increasingly recognized as a disease spectrum encompassing a range of inflammatory states in the sinonasal cavity, with non-type 2 inflammatory disease on one end, type 2 inflammatory, eosinophil-heavy disease on the other and an overlap of both in different proportions in between. Abundance in research on the immune mechanisms of CRS has revealed various new endotypes that hold promise as biomarkers for the development of targeted therapies in severe, uncontrolled CRS. The introduction of precision medicine to manage this chronic, complex condition is a step forward in providing individualized care for all patients with CRS. In this review, the latest research on the pathophysiology of CRS with a focus on potential novel biomarkers and treatment options over the last 2 years are summarized and integrated into a suggested model of precision medicine in CRS.

Abstract
PURPOSE OF REVIEW To improve our appreciation of the burden of chronic rhinosinusitis (CRS) and to understand better how to ease that burden. RECENT FINDINGS The burden of CRS is high. At an individual level, this burden is due to rhinologic symptoms as well as more systemic symptoms. At a societal level, the indirect costs of CRS, mostly due to reduced productivity, are higher than the direct costs. Surgical treatment has been found to be effective in addressing both the individual and societal burdens. Endotyping is just beginning to usher in the potential for personalized, precision treatments in CRS. We understand much about the burden of CRS but more remains to be learned, especially as newer expensive treatments become available. By appreciating the high burden of CRS, we can fulfill our mission to effectively lift that burden.

Abstract
Introduction: Allergic rhinitis and chronic rhinosinusitis, with and without nasal polyps, are the most common chronic inflammatory diseases of the upper airways. They both cause relevant respiratory symptoms and a substantial detriment to patients' quality of life, mainly in uncontrolled and severe patients.Areas covered: This review aims to present the most recent evidence on current and emerging biologic therapies for allergic rhinitis and chronic rhinosinusitis and discuss their potential implementation in clinical practice. To select relevant literature for inclusion in this review, we conducted a literature search using the PubMed database, using terms 'biologics OR biological agents', 'allergic rhinitis' and 'chronic rhinosinusitis'. The literature review was performed for publication years 2009-2019, restricting the articles to humans and English language publications.Expert opinion: Biological therapies represent a potential step forward in providing individualized care for all patients with uncontrolled severe upper airway diseases. Biologics recently showed promising results for the treatment of severe uncontrolled allergic rhinitis and chronic rhinosinusitis with nasal polyps with or without associated asthma. Endotyping inflammatory pathways and identifying related biomarkers remain the major challenge for positioning biologics in the care pathway of chronic respiratory diseases.

Abstract
Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a frequent disorder. From a clinical and an immunopathological point of view, different phenotypes and endotypes have been identified. The frequent comorbidity with asthma allowed to pave the way to the use of biological agents for the treatment of CRSwNP. Biological agents are targeted to antagonize IgE, interleukin (IL) 4, IL-5, and IL-13 at present. However, a correct and appropriate workup is mandatory, mainly concerning the exact definition of the specific pheno-endotype. The preliminary outcomes are promising, even though there is a need for well-established indications, criteria of responsiveness, duration, and safety. On the other hand, this personalized medicine could be fruitfully integrated with gold-standard medications, such as intranasal corticosteroids. As CRSwNP is a chronic disorder, treatment should be long-lasting, so complementary anti-inflammatory treatments could be opportunely integrated and/or alternated to steroids. (www.actabiomedica.it)

Abstract
INTRODUCTION In the United States, 5% of patients represent up to 55% of all health care costs. This study sought to define healthcare utilization patterns among super-utilizers, as well as assess possible variation in patient outcomes. METHODS Medicare super-utilizers undergoing either a total hip or knee arthroplasty were identified and entered into a cluster analysis using annual preoperative charges to identify distinct patterns of utilization. RESULTS Among 19,522 super-utilizers who underwent THA or TKA, there was a marked heterogeneity in overall utilization with 5 distinct clusters of utilization patterns. Of note, comorbidity burden was similar among the 5 clusters. Patient outcomes also varied by Cluster type, ranging from 6.9% to 16.5% experiencing complications and 1.0%-3.2% experiencing 90-day mortality. CONCLUSION While previous studies have suggested that super-utilizers are a homogenous group of patients, the current study demonstrated a large degree of heterogeneity within super-utilizers. Variations in utilization patterns were associated with postoperative outcomes and subsequent health care costs.

Abstract
AIMS In chronic rhinosinusitis with nasal polyps (CRSwNP), tools based on objective evidence, such as histopathology, are needed to assist clinical decision-making. The main aim of this exploratory investigation was to determine whether structured histopathology could be used to classify CRSwNP in homogeneous histological clusters. METHODS AND RESULTS A cohort of 135 CRSwNP patients was assessed, on the basis of clinicopathological features: allergic fungal rhinosinusitis (17 patients); non-steroidal anti-inflammatory drug-exacerbated respiratory disease (19 patients); intrinsic asthma (18 patients); extrinsic asthma (21 patients); allergy (21 patients); histologically eosinophilic (22 patients); and histologically non-eosinophilic (17 patients). For structured histopathology, we considered: the degree of inflammation; eosinophil count; eosinophil aggregates; neutrophil infiltration; goblet cell hyperplasia; basement membrane thickening; fibrosis; hyperplastic/papillary changes; squamous metaplasia; mucosal ulceration; and subepithelial oedema. Cluster analysis identified four distinct sets of cases. On discriminant analysis, the global error rate was 1.48%, and the stratified error rates were 4.34%, 0%, 0%, and 0% for clusters 1, 2, 3 and 4, respectively. Cluster 1 was characterised by infrequent fibrosis (<4.5% of cases). Cluster 2 mainly featured neutrophil infiltration in 100% of cases, hyperplastic/papillary changes in 70% of cases, and fibrosis in 65% of cases. Cluster 3 showed fibrosis in 100% of cases. Cluster 4 showed hyperplastic/papillary changes in 100% of cases, and fibrosis in 92% of cases. CONCLUSIONS This study shows that cluster analysis can identify different histotypes among CRSwNP patients. The next step will be to investigate, in a larger series, the clinical (e.g. prognostic) implications of identifying such homogeneous clusters of patients with CRSwNP on the basis of their structured histopathology.

Abstract
BACKGROUND Patient-specific and disease-specific factors shape the course of chronic rhinosinusitis (CRS) and its response to treatment, with optimal management involving interventions tailored to these factors. Recent evidence suggests CRS inflammatory signatures depend on age. The objective of this study was to determine whether age also influences quality-of-life (QOL) and postoperative outcomes. METHODS Retrospective analysis of prospectively collected QOL data from 403 adults with medically refractory CRS who underwent functional endoscopic sinus surgery (FESS) at a tertiary care medical center between 2014 and 2018 was undertaken. Total and subdomain scores from the 22-item Sino-Nasal Outcome Test (SNOT-22) and the Short Form 8 Health Survey (SF-8) measure of general health completed at preoperative and postoperative visits were reviewed. RESULTS Patients were divided into young (18 to 39 years, n = 100), middle-aged (40 to 59 years, n = 172), and elderly (≥60 years, n = 131) groups. Baseline total SNOT-22 scores differed between groups (p = 0.01), with middle-aged patients having the highest symptom burden and elderly patients having the lowest. Similar patterns were observed for SNOT-22 subdomains. Elderly patients reported smaller improvements and were less likely to achieve a minimally important clinical difference. CRS patients had worse SF-8 scores compared to the general population, and elderly patients were the least likely to match population norms following surgery. Age was an independent predictor of QOL outcomes after FESS. CONCLUSION Age may play a significant role in CRS pathophysiology, symptom burden, and surgical outcomes. Elderly patients report smaller improvements in disease-specific and general health QOL after surgery. CRS management in the elderly population should incorporate age-dependent differences in symptom burden and expectations into treatment algorithms.

Abstract
OBJECTIVE Medically Unexplained Physical Symptoms (MUPS) are a major burden on both patients and society and frequently develop into chronic MUPS. Self-management interventions may prevent moderate MUPS from becoming chronic. Tailoring interventions to the patient population is strongly recommended. This can be facilitated by identifying subgroups based on self-management skills. This study aimed to identify these subgroups and their clinical profiles in primary care patients with moderate MUPS. METHODS A cross-sectional study was performed on baseline measurements from a randomized clinical trial (PARASOL-study). To identify subgroups based on self-management skills, a hierarchical cluster analysis was conducted for adults with moderate MUPS from primary health care centers. Self-management skills were measured with the Health education impact Questionnaire. Cluster variables were seven constructs of this questionnaire. Additionally, specific patient profiles were determined by comparing the identified clusters on the clinical variables pain, fatigue and physical functioning. RESULTS Four subgroups were identified: High-Self-Management Skills (SMS) (n = 29), Medium-SMS (n = 55), Low-SMS (n = 49) and Active & Low Distress-SMS (n = 20). The latter showed a distinctly different pattern on cluster variables, while the other subgroups differed significantly on means of the cluster variables (p < .001). On clinical variables, significant differences between subgroups were mainly found on fatigue and physical functioning. CONCLUSION This study found four specific subgroups based on self-management skills in moderate MUPS-patients. One subgroup demonstrated a distinctly different pattern on self-management skills. In other subgroups, more similar patterns on self-management skills were found that negatively correlated with pain and fatigue and positively correlated with physical functioning.

Discriminant analysis followed by unsupervised cluster analysis including exosomal cystatins predict presence of chronic rhinosinusitis, phenotype, and disease severity. Int Forum Allergy Rhinol 2019; 9:1069-1076. [PMID: 31322841 DOI: 10.1002/alr.22380] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 06/10/2019] [Accepted: 06/11/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Cystatins are epithelial protease inhibitors that participate in sinonasal immunity and inflammation. Nasal mucus-derived exosomes (NMDEs) are small vesicles secreted by epithelial cells that carry protein cargo reflective of their host cell. NMDEs have been used as a noninvasive biomarker source to study chronic rhinosinusitis with nasal polyps (CRSwNP) proteomics with superior sensitivity to whole mucus. The purpose of this study was to noninvasively quantify exosomal cystatins in a heterogenous population to determine their utility in predicting phenotype and disease severity. METHODS This was an Institutional Review Board-approved study in which NMDEs were purified from 105 patients undergoing sinonasal surgery by ultracentrifugation. Demographic and clinical variables were collected and phenotypes were assigned a priori. Linear discriminant analysis was executed based on normalized Cystatin values as phenotype predictor variables. Unsupervised cluster analysis was performed using Ward's linkage followed by Duda/Hart Je(2)/Je(1) index cluster stopping rules. Analysis of variance (ANOVA), Welch's test, and Fisher's exact tests were used for continuous and categorical variables. RESULTS NMDE Cystatin-2 expression segregated by phenotype (mean ± standard error [SEM]): control (23.4 ± 4.2 pg/µg, n = 32); CRS without NP (CRSsNP) (56.6 ± 8.3 pg/µg, n = 33); and CRSwNP (130.5 ± 16.7 pg/µg, n = 40) (p < 0.0001). Seven clusters were identified among patients where the highest NMDE Cystatin-2 levels clustered with asthma, tissue eosinophilia, and aspirin-exacerbated respiratory disease (AERD). CONCLUSION Cystatin levels in NMDEs predict CRS phenotype and disease severity. As a "liquid biopsy," noninvasive NMDE collection offers a promising opportunity to study disease pathophysiology, discriminate disease states, and potentially reveal novel therapeutic targets.

Abstract
OBJECTIVES This article reviews the principles of unsupervised learning, a novel technique which has increasingly been reported as a tool for the investigation of chronic rhinosinusitis (CRS). It represents a paradigm shift from the traditional approach to investigating CRS based upon the clinically recognized phenotypes of "with polyps" and "without polyps" and instead relies upon the application of complex mathematical models to derive subgroups which can then be further examined. This review article reports on the principles which underlie this investigative technique and some of the published examples in CRS. METHODS This review summarizes the different types of unsupervised learning techniques which have been described and briefly expounds upon their useful applications. A literature review of studies which have unsupervised learning is then presented to provide a practical guide to its uses and some of the new directions of investigations suggested by their findings. RESULTS The commonest unsupervised learning technique applied to rhinology research is cluster analysis, which can be further subdivided into hierarchical and non-hierarchical approaches. The mathematical principles which underpin these approaches are explained within this article. Studies which have used these techniques can be broadly divided into those which have used clinical data only and that which includes biomarkers. Studies which include biomarkers adhere closely to the established canon of CRS disease phenotypes, while those that use clinical data may diverge from the typical "polyp versus non-polyp" phenotypes and reflect subgroups of patients who share common symptom modifiers. SUMMARY Artificial intelligence is increasingly influential in health care research and machine learning techniques have been reported in the investigation of CRS, promising several interesting new avenues for research. However, when critically appraising studies which use this technique, the reader needs to be au fait with the limitations and appropriate uses of its application.

Abstract
BACKGROUND Patient perceptions and preferences related to postoperative surveillance are not yet well defined. METHODS A cross-sectional analysis of the surveillance practice preferences and attitudes was undertaken based on subgroups derived from clustering participants for measures of well-being, including financial toxicity, emotional, family/social, and functional well-being. RESULTS Among 212 participants, the average age was 58.1 years and most patients were female (57.1%) and white (90.2%). Common malignancies included melanoma/sarcoma (26.4%), thyroid (25.5%), breast (18.9%), gastrointestinal (18.4%), and lung (7.5%) cancer. Respondents within the highest well-being subgroup rated their perception of communication as being the highest more consistently compared with the other well-being subgroups (P = .005). Participants with the highest level of well-being felt more reassured by follow-up appointments (Subgroup 1, Med = 4.00, interquartile range (IQR) = 0.25 vs subgroup 4, Med = 3.75, IQR = 0.73, P = .023). In contrast, patients with the lowest sense of well-being had the highest level of nervousness related to surveillance (subgroup 1, Med = 1.60, IQR = 1.00 vs subgroup 4, Med = 2.20, IQR = 1.15, P < .001). There were no differences in surveillance frequency preferences among different well-being subgroups. CONCLUSION Attitudes towards postoperative surveillance varied with regard to perception of provider communication, nervous anticipation, and assuredness depending on overall patient well-being. Providers should attempt to assess patient well-being as part of a tailored approach to postcancer surgery surveillance.

Abstract
OBJECTIVE This study investigates the impact of histopathologic parameters on quality of life outcomes in patients with chronic rhinosinusitis. SETTING Hospital of Zhejiang University. STUDY DESIGN Retrospective analysis of collected data. SUBJECTS AND METHODS One hundred and twenty patients with chronic rhinosinusitis (CRS) who underwent endoscopic sinus surgery were recruited. Clinical features, CT evaluation, pre and postoperative SNOT-22 scores and histopathologic findings were collected. Tissue eosinophils and mucosal remodeling were analyzed relative to clinical features and outcomes 12 months postoperatively. RESULTS Symptom improvement was seen for the entire population. Eosinophilic CRS had significantly worse preoperative and postoperative SNOT-22 scores than non- eosinophilic CRS. Symptom improvement in eosinophilic CRS after surgery was less than that of non-eosinophilic CRS. There was no significant association between preoperative and postoperative SNOT-22 scores and remodeling markers. However, patients with basement membrane thickening showed less reductions of SNOT-22 score postoperatively. CONCLUSIONS Presence of mucosal eosinophilia and basal membrane thickening appear to be the main factors adversely affect the symptom control of surgical intervention. Routine histopathology analysis can provide meaningful information for prognostication of surgical outcome.

Abstract
Chronic rhinosinusitis (CRS) is a heterogeneous chronic inflammatory condition of the paranasal sinuses and nasal passage. It is characterized as inflammation of the sinonasal passage, presenting with two or more symptoms (nasal blockage, secretions, facial pain and headaches) for more than 12 weeks consecutively. The disease is phenotypically differentiated based on the presence of nasal polyps; CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Traditionally, CRSwNP has been associated with a type 2 inflammatory profile, while CRSsNP has been associated with a type 1 inflammatory profile. Extensive work in characterizing the inflammatory profiles of CRS patients has challenged this dichotomy, with great variation both between and within populations described. Recent efforts of endotyping CRS based on underlying pathophysiology have further highlighted the heterogeneity of the disease, revealing mixed inflammatory profiles coordinated by a number of inflammatory cell types. This review will highlight the current understanding of inflammation in CRS, and discuss the importance and impact of refining this understanding in the development of appropriate treatment options for CRS sufferers.

Abstract
Asthma is a prevalent inflammatory condition of the lower airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchial hyperresponsiveness (BHR). Symptomatically, these patients may demonstrate wheezing, breathlessness, chest tightness, and coughing. This disease is a substantial burden to a growing population worldwide that currently exceeds 300 million individuals. This is a condition that is frequently encountered, but often overlooked in the field of otolaryngology. In asthma, comorbid conditions are routinely present and contribute to respiratory symptoms, decreased quality of life, and poorer asthma control. It is associated with otolaryngic diseases of the upper airways including allergic rhinitis (AR) and chronic rhinosinusitis (CRS). These conditions have been linked epidemiologically and pathophysiologically. Presently, they are considered in the context of the unified airway theory, which describes the upper and lower airways as a single functional unit. Thus, it is important for otolaryngologists to understand asthma and its complex relationships to comorbid diseases, in order to provide comprehensive care to these patients. In this article, we review key elements necessary for understanding the evaluation and management of asthma and its interrelatedness to CRS.

Abstract
PURPOSE OF REVIEW Our scope is the presentation of research and clinical progresses in relation to precision medicine that are expected to alter our clinical practice in relation to chronic rhinosinusitis (CRS). Current knowledge on phenotypes and endotypes, biomarkers, and clinical markers for diagnosis, medical and surgical therapy, and prognosis is presented as well as the role of precision medicine in United Airway Disease and SCUAD (severe-uncontrolled chronic upper airway inflammation). RECENT FINDINGS Current technological progresses, mostly in relation to molecular biology and information technology, have permitted more detailed pathophysiological assessments and multidimensional approaches in airways diseases. Based on the concept of united airways diseases, new classification schemes, called endotypes, have been proposed for CRS. In addition, novel biological treatments that have been introduced for the treatment of asthma show great promise as well for severe uncontrolled cases of CRS with nasal polyps. Central to this approach are new biomarkers that are being examined in relation to complex bio-clinical traits of CRS. As this narrative review of the aforementioned precision medicine initiatives in relation to CRS advances, a modification of current practice is expected not only for severe chronic upper airways diseases in tertiary centers but also for milder and more common cases that are being encountered in the community.

Abstract
Common variable immunodeficiency (CVID) is a complex disease with various influences on perceived health, which correlate with different outcomes, including new morbidity and mortality. Our hypothesis was that CVID patients fall into distinct clusters of perceived health which can inform care. Ward hierarchical cluster analysis and K-means cluster analysis were performed on data of 209 CVID patients to identify subgroups regarding their self-reported physical and mental health status, assessed by the physical (PCS) and mental component scores (MCS) of the Short Form-12 (SF-12). Four clusters of CVID-patients were identified. Cluster 1 was the largest cluster, characterized by a relatively high physical and mental health status (44·0%). In contrast, cluster 2 (21·1%) included patients with low physical and mental health status. Clusters 3 and 4 were mixed groups with high mental and low physical health (15·8%) and vice versa (19·1%). Significant differences between the clusters were found for patient-reported outcomes such as work ability and health literacy, but not for CVID-associated complications such as enteropathy, interstitial lung disease, granulomatosis, lymphadenopathy and autoimmune cytopenia or laboratory parameters such as immunoglobulin levels or B cell-based classification. The results suggest different subgroups of CVID patients with contrasting individual needs which, surprisingly, did not differ in clinical or laboratory characteristics. The main finding of this study is that patients with CVID fall into four distinct clusters according to perceived health, which are largely independent of CVID complications.

Abstract
Chronic rhinosinusitis is a complex disease that exists along the inflammatory spectrum between types 1 and 2 inflammation. The classic phenotypic differentiation of chronic rhinosinusitis based on the presence or absence of inflammatory polyps remains one of the best differentiators of response to therapy. Development of biologics for the treatment of atopic disease and asthma and topical therapies for sinusitis have placed renewed emphasis on understanding the pathophysiology of polyp disease. Identification of key markers of polyposis will allow for better stratification of inflammatory polyp disease endotypes to objectively identify medical therapies and track response to treatment.

Abstract
Objective Whether or not depression affects the control or severity of asthma is unclear. We performed a cluster analysis of asthma patients with depressive symptoms to clarify their characteristics. Methods Multiple medical institutions in Niigata Prefecture, Japan, were surveyed in 2014. We recorded the age, disease duration, body mass index (BMI), medications, and surveyed asthma control status and severity, as well as depressive symptoms and adherence to treatment using questionnaires. A hierarchical cluster analysis was performed on the group of patients assessed as having depression. Results Of 2,273 patients, 128 were assessed as being positive for depressive symptoms [DS(+)]. Thirty-three were excluded because of missing data, and the remaining 95 DS[+] patients were classified into 3 clusters (A, B, and C). The patients in cluster A (n=19) were elderly, had severe, poorly controlled asthma, and demonstrated possible adherence barriers; those in cluster B (n=26) were elderly with a low BMI and had no significant adherence barriers but had severe, poorly controlled asthma; and those in cluster C (n=50) were younger, with a high BMI, no significant adherence barriers, well-controlled asthma, and few were severely affected. The scores for depressive symptoms were not significantly different between clusters. Conclusion About half of the patients in the DS[+] group had severe, poorly controlled asthma, and these clusters were able to be distinguished by their Adherence Starts with Knowledge (ASK)-12 score, which reflects adherence barriers. The control status and severity of asthma may also be related to the age, disease duration, and BMI in the DS[+] group.

Abstract
BACKGROUND The expression of chronic rhinosinusitis (CRS) is multidimensional. Disease heterogeneity in patients with CRS remains poorly understood. This study aimed to identify endotypes of CRS using cluster analysis by integrating multidimensional characteristics and to explore their association with treatment outcomes. METHODS A total of 28 clinical variables and 39 mucosal cellular and molecular variables were analyzed using principal component analysis. Cluster analysis was performed on 246 prospectively recruited Chinese CRS patients with at least 1-year postoperative follow-up. Difficult-to-treat CRS was characterized in each generated cluster. RESULTS Seven subject clusters were identified. Cluster 1 (13.01%) was comparable to the classic well-defined eosinophilic CRS with polyps, having severe disease and the highest proportion of difficult-to-treat CRS. Patients in cluster 2 (16.26%) and cluster 4 (13.82%) had relatively lower proportions of presence of polyps and presented mild inflammation with moderate proportions of difficult-to-treat cases. Subjects in cluster 2 were highly atopic. Cluster 3 (7.31%) and cluster 6 (21.14%) were characterized by severe or moderate neutrophilic inflammation, respectively, and with elevated levels of IL-8 and high proportions of difficult-to-treat CRS. Cluster 5 (4.07%) was a unique group characterized by the highest levels of IL-10 and lacked difficult-to-treat cases. Cluster 7 (24.39%) demonstrated the lowest symptom severity, a low proportion of difficult-to-treat CRS, and low inflammation load. Finally, we found that difficult-to-treat CRS was associated with distinct clinical features and biomarkers in the different clusters. CONCLUSIONS Distinct clinicopathobiologic clusters of CRS display differences in clinical response to treatments and characteristics of difficult-to-treat CRS.

Abstract
Purpose of Review Chronic rhinosinusitis is a disease with high prevalence, significant impact on health-related quality of life (HRQoL) and it is associated with substantial healthcare and productivity costs. We face an urgent need to improve the level of disease control and achieve higher patient satisfaction and disease prevention. Precision medicine is increasingly recognized as the way forward in optimal patient care. The combination of personalized care, prevention of disease, prediction of success of treatment, and participation of the patient in the elaboration of the treatment plan is expected to guarantee the best possible therapeutic approach for individuals suffering from a chronic disabling condition. Recent Findings This is a narrative review on the current state of endotypes, biomarkers, and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses. Different phenotypes of rhinitis and chronic rhinosinusitis (CRS) have been described based on symptom severity and duration, atopy status, level of control, comorbidities, and presence or absence of nasal polyps in CRS. The underlying pathophysiological mechanisms are diverse, with different endotypes being recognized. Novel emerging therapies are targeting specific pathophysiological pathways or endotypes. This endotype-driven treatment approach requires careful selection of the patient population who might benefit from a specific treatment. Summary This review provides a comprehensive overview of the current state of endotypes, biomarkers and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses.

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 (CRS) is a prevalent and disabling condition of the nose and sinuses. The natural history of CRS symptoms in a general population sample has not been previously studied. OBJECTIVE In a general population-based sample from Pennsylvania, we used 2 questionnaires mailed 6 months apart to estimate the prevalence of, and identify predictors for, stability or change in symptoms over time. METHODS We mailed the baseline and 6-month follow-up questionnaires to 23,700 primary care patients and 7,801 baseline responders, respectively. We categorized nasal and sinus symptoms using European Position Paper on Rhinosinusitis (EPOS) epidemiologic criteria. We defined 6 symptom groups over time on the basis of the presence of CRS symptoms at baseline and follow-up. We performed multivariable survey logistic regression controlling for confounding variables comparing persistent versus nonpersistent, recurrent versus stable past, and incident versus never. RESULTS There were 4,966 responders at follow-up: 558 had persistent symptoms, 190 recurrent symptoms, and 83 new symptoms meeting EPOS criteria for CRS. The prevalence of persistent symptoms was 4.8% (95% CI, 3.8-5.8), whereas the annual cumulative incidence of new symptoms was 1.9% and of recurrent symptoms was 3.2%. More severe symptoms at baseline were associated with persistence, whereas minor symptoms, allergies, and multiple treatments were associated with the development of new symptoms. CONCLUSIONS Less than half with nasal and sinus symptoms meeting CRS EPOS criteria in our general, regional population had symptom persistence over time, with symptom profiles at baseline and age of onset being strongly associated with stability of symptoms.

Abstract
PURPOSE OF REVIEW The purpose of this review is to address the most recent advances in the medical therapy for chronic rhinosinusitis (CRS), define recalcitrant and refractory CRS, and discuss the productivity costs associated with CRS. RECENT FINDINGS Recent studies evaluating anti-IL-4 receptor α antibodies and calcium channel blockers have demonstrated promising early results during management of CRS. Recent appropriateness criteria have been developed to assist clinicians with defining which patients have 'refractory' CRS and may be considered candidates for endoscopic sinus surgery. Productivity costs appear to be associated with disease severity and can be reduced with appropriate interventions. SUMMARY Topical corticosteroid therapy and high volume saline irrigation continue to be the cornerstone to medical therapy, whereas use of systemic corticosteroids and antibiotics depends on CRS phenotype and presence of acute exacerbation. More research is needed before routine use of novel immunomodulatory therapies such as anti-IL5, anti-IgE, anti-IL4, and calcium channel blockers. Clinicians should apply an appropriate definition for refractory CRS when discussing role of sinus surgery. Assessing the degree of work productivity impairment can assist in treatment decision-making and may help predict treatment outcomes.

Abstract
PURPOSE OF REVIEW The objective of this article is to provide an updated review of the economic burden of chronic rhinosinusitis (CRS) and discuss how both medical and surgical interventions impact direct and indirect costs related to CRS. By understanding the economics of CRS, clinicians may improve the patient-centeredness of their care and help distinguish between low and high value interventions. RECENT FINDINGS Direct costs related to CRS are primarily driven by outpatient physician visits, prescription medical therapy, and endoscopic sinus surgery (ESS). CRS produces large indirect costs and these costs often vary based on the severity of the patients CRS-specific QoL impairment. The overall direct cost related to CRS is estimated to range between $10 and $13 billion per year in the USA. The overall indirect cost related to CRS-related losses in work productivity is estimated to be in excess of $20 billion per year. In the appropriate patients with refractory CRS, ESS provides significant reductions in both direct and indirect costs; however, continued medical therapy alone may be a high value intervention in select patients who have lower severity in their baseline QoL and work productivity.

Int Forum Allergy Rhinol 2017; 7:734-740. [PMID: 28519966 PMCID: PMC5751751 DOI: 10.1002/alr.21940] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Revised: 01/09/2017] [Accepted: 02/07/2017] [Indexed: 02/04/2023]
Abstract
BACKGROUND Chronic rhinosinusitis (CRS) significantly impacts olfaction. However, the relationship between objective olfaction and patient-reported olfactory-specific quality of life (QOL) is not well understood. Furthermore, objective olfactory testing can be time consuming, so we sought to determine if patient-reported olfactory QOL can be used as screening tool for olfactory dysfunction. METHODS Olfactory dysfunction was evaluated in 109 patients with CRS using the Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) and the Sniffin' Sticks Test, assessing for olfactory threshold, discrimination, identification, and overall composite scores (TDI; composite score of threshold, discrimination, and identification). Regression analysis was performed to correlate olfactory metrics and patient and disease-specific factors with QOD-NS scores. Optimal QOD-NS scores to classify patients based upon objective olfactory function were established. RESULTS Bivariate and multivariate regression analyses of QOD-NS and CRS-associated comorbidities, objective measures of disease, demographics, and CRS-specific QOL were performed. Non-white race, depression, and worse 22-item Sino-Nasal Outcome Test (SNOT-22) scores correlated with worse QOD-NS scores (p < 0.005). Worse TDI scores correlated with worse QOD-NS scores, and discrimination had the strongest correlation (p < 0.001). Mean ± standard deviation (SD) QOD-NS scores for normosmia, hyposmia, and anosmia were 44 ± 7.2, 35.7 ± 12.8, and 31.6 ± 10.7, respectively. Receiver operating characteristic curve analysis revealed an area under the curve of 0.770 (p < 0.001), and a QOD-NS cutoff of 38.5 to have maximal Youden's index to define normal vs abnormal TDI score. CONCLUSION In CRS, QOD-NS correlates with non-white race, depression, SNOT-22, and TDI score, with discrimination having the strongest correlation. The QOD-NS also appears to be a feasible tool for olfaction screening.

Olfactory disturbances in ageing with and without dementia: towards new diagnostic tools. The Journal of Laryngology & Otology 2017; 131:572-579.

Abstract
BACKGROUND Olfactory disorders increase with age and often affect elderly people who have pre-dementia or dementia. Despite the frequent occurrence of olfactory changes at the early stages of neurodegenerative disorders such as Alzheimer's disease, olfactory disorders are rarely assessed in daily clinical practice, mainly due to a lack of standardised assessment tools. The aims of this review were to (1) summarise the existing literature on olfactory disorders in ageing populations and patients with neurodegenerative disorders; (2) present the strengths and weaknesses of current olfactory disorder assessment tools; and (3) discuss the benefits of developing specific olfactory tests for neurodegenerative diseases. METHODS A systematic review was performed of literature published between 2000 and 2015 addressing olfactory disorders in elderly people with or without Alzheimer's disease or other related disorders to identify the main tools currently used for olfactory disorder assessment. RESULTS Olfactory disorder assessment is a promising method for improving both the early and differential diagnosis of Alzheimer's disease. However, the current lack of consensus on which tests should be used does not permit the consistent integration of olfactory disorder assessment into clinical settings. CONCLUSION Otolaryngologists are encouraged to use olfactory tests in older adults to help predict the development of neurodegenerative diseases. Olfactory tests should be specifically adapted to assess olfactory disorders in Alzheimer's disease patients.

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
The purpose of this study is to use unsupervised cluster methodology to identify phenotype and mucosal eosinophilia endotype subgroups of patients with medical refractory chronic rhinosinusitis (CRS), and evaluate the difference in quality of life (QOL) outcomes after endoscopic sinus surgery (ESS) between these clusters for better surgical case selection. A prospective cohort study included 131 patients with medical refractory CRS who elected ESS. The Sino-Nasal Outcome Test (SNOT-22) was used to evaluate QOL before and 12 months after surgery. Unsupervised two-step clustering method was performed. One hundred and thirteen subjects were retained in this study: 46 patients with CRS without nasal polyps and 67 patients with nasal polyps. Nasal polyps, gender, mucosal eosinophilia profile, and prior sinus surgery were the most discriminating factors in the generated clusters. Three clusters were identified. A significant clinical improvement was observed in all clusters 12 months after surgery with a reduction of SNOT-22 scores. There was a significant difference in QOL outcomes between clusters; cluster 1 had the worst QOL improvement after FESS in comparison with the other clusters 2 and 3. All patients in cluster 1 presented CRSwNP with the highest mucosal eosinophilia endotype. Clustering method is able to classify CRS phenotypes and endotypes with different associated surgical outcomes.
