Reasons for rejection of rhinoplasty seeking patients: a multicentre observational study.

BACKGROUND: To date, research on preoperative patient selection has mainly focused on patient personality, with body dysmorphic disorder (BDD) being the most studied. Despite the many reasons for not planning a rhinoplasty, no data are available on the nature of these reasons. Our aim is to conduct a multicentre international observational study on the reasons for rejection of patients seeking rhinoplasty in 5 tertiary rhinoplasty care centres. METHODS: Surgeons documented the reasons for not scheduling a rhinoplasty in consecutive patients who consulted them between January 2021 and March 2022 using a predefined list of reasons for rejection. Surgeons were also asked to report on the patient attitudes after rejection, and about the advice given to patients in the event of refusal. RESULTS: 186 patients seeking rhinoplasty were included. Multiple reasons for rejection were present in 76% of patients, with a mean of 2.9 reasons for rejection per patient. Overall, patient-related factors were most frequently associated with rejection (64.3%), followed by nose-related factors (28.4%), surgeon-related factors (6.0 %) and surgery-related factors (1.3%). The presence of severe BDD symptoms was reported in only 11.3% of the rejected patients. Patients rejected for rhinoplasty were advised to reconsider the surgery (32.8 %) and/or were referred to another surgeon (32.8%). No further action was taken in 39.8% of the patients. Of the patients who were rejected, most had a neutral (39.2 %) or positive (37.1 %) attitude in relation to the lack of rhinoplasty planning. CONCLUSION: This study highlights the variety of reasons for which patients seeking rhinoplasty are not considered good candidates for a rhinoplasty, with patient-related factors being more prevalent than nose-related and other factors. Increasing awareness on the impact of adequate patient selection for rhinoplasty may contribute to better outcomes in rhinoplasty.

Nasal hyperreactivity in allergic rhinitis and chronic rhinosinusitis with polyps: a role for neuronal pathways.

BACKGROUND: Nasal hyperreactivity (NHR) is prevalent in all chronic upper airway inflammatory phenotypes, including allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP). Although NHR in patients with non-allergic rhinitis is mediated by neuronal pathways, AR and CRSwNP are mainly characterized by type 2 inflammation. METHODS: Eighteen healthy controls and 45 patients with symptomatic AR/CRSwNP underwent a cold, dry air (CDA) provocation test for objective diagnosis of NHR. Before and after, questionnaires were filled out and nasal secretions and biopsies were collected. Markers for neurogenic inflammation (substance P, calcitonin gene-related peptide, neurokinin A), epithelial activation (IL-33), and histamine were measured in secretions by ELISA; and expression of neuronal markers PGP9.5, TRPV1, and TRPM8 was studied in biopsies by RT-q-PCR. Effects of histamine on TRPV1/A1 were studied with Ca2+-imaging using murine trigeminal neurons. RESULTS: CDA-provocation reduced peak nasal inspiratory flow (PNIF) of patients with subjective NHR but not of non-NHR controls/patients CDA-provocation reduced peak nasal inspiratory flow (PNIF) of patients with subjective NHR but not of non-NHR controls/patients. Subjective (subjectively reported effect of CDA) and objective (decrease in PNIF) effects of CDA were significantly correlated. Levels of neuropeptides and histamine in nasal secretions and mRNA expression of PGP9.5, TRPV1, and TRPM8 correlated with CDA-induced PNIF-reduction. CDA-provocation induced an increase in IL-33-levels. Both TRPV1 and TRPA1 expressed on afferent neurons were sensitized by exposure to histamine. CONCLUSION: NHR is not an on/off phenomenon but spans a continuous spectrum of reactivity. A neurogenic inflammatory background and increased histamine-levels are risk factors for NHR in AR/CRSwNP.

EPOS2020/EUFOREA expert opinion on defining disease states and therapeutic goals in CRSwNP.

Severe chronic rhinosinusitis with nasal polyps (CRSwNP), a form of diffuse bilateral (usually type 2) CRS, is a debilitating disease with a significant impact on quality of life (QoL). With novel knowledge and treatment options becoming available, there is a growing need to update or revise key definitions to enable communication across different specialties dealing with CRS, and to agree on novel goals of care in CRSwNP. The European Forum for Research and Education in Allergy and Airway diseases (EUFOREA) and EPOS expert members discussed how to measure treatment responses and set new treatment goals for CRSwNP. In this paper a consensus on a list of definitions related to CRSwNP is provided: control, remission, cure, recurrence/exacerbation, treatable traits, remodeling, progression, and disease modification. By providing these definitions, the involved experts hope to improve communication between all stakeholders involved in CRSwNP treatment for use in routine care, basic and clinical research and international guidelines aimed to harmonize and optimize standard of care of patients with CRSwNP in the future.

Fluticasone propionate suppresses the SARS-CoV-2 induced increase in respiratory epithelial permeability in vitro.

BACKGROUND: Disruption of the nasal epithelial barrier is believed to play a role in Coronavirus Disease-2019 (COVID-19) outcomes. Fluticasone propionate has been shown to restore the nasal epithelial barrier in allergic rhinitis to the level of healthy controls. The therapeutic potential of nasal steroid sprays in COVID-19 has recently been reported. However, further insight into the mode of action is warranted. OBJECTIVES: To explore the in vitro mechanisms of the preventive potential of fluticasone propionate in SARS-CoV-2 infection. METHODS: Human air liquid interface cultures of Calu-3 cells and primary nasal epithelial cells isolated from healthy donors were used to investigate the preventive effect of fluticasone propionate on SARS-CoV-2 induced barrier disruption, virus replication and ACE2 expression. RESULTS: 48 hours pre-treatment with fluticasone propionate prevented the SARS-CoV-2 induced increase in fluorescein isothiocyanate-dextran 4 kDa permeability and reduced infection with SARS-CoV-2. Pre-treatment with fluticasone propionate also decreased ACE2 expression in SARS-CoV-2 infected Calu-3 cells. CONCLUSION: Fluticasone propionate pre-treatment prevented SARS-CoV-2 increased epithelial permeability, reduced ACE2 expression and SARS-CoV-2 infection, underscoring the therapeutic potential of fluticasone propionate in the context of COVID-19.

EPOS/EUFOREA update on indication and evaluation of Biologics in Chronic Rhinosinusitis with Nasal Polyps 2023.

Severe chronic rhinosinusitis with nasal polyps (CRSwNP) is a debilitating disease with a significant impact on the quality of life (QoL). It is typically characterized by a type 2 inflammatory reaction and by comorbidities such as asthma, allergies and NSAID-Exacerbated Respiratory Disease (N-ERD). Here, the European Forum for Research and Education in Allergy and Airway diseases discusses practical guidelines for patients on biologic treatment. Criteria for the selection of patients who would benefit from biologics were updated. Guidelines are proposed concerning the monitoring of the drug effects that provide recognition of responders to the therapy and, subsequently, the decision about continuation, switching or discontinuation of a biologic. Furthermore, gaps in the current knowledge and unmet needs were discussed.

Consensus criteria for chronic rhinosinusitis disease control: an international Delphi Study.

BACKGROUND: Chronic rhinosinusitis (CRS) disease control is a global metric of disease status for CRS. While there is broad acceptance that it is an important treatment goal, there has been inconsistency in the criteria used to define CRS control. The objective of this study was to identify and develop consensus around essential criteria for assessment of CRS disease control. METHODS: Modified Delphi methodology consisting of three rounds to review a list of 24 possible CRS control criteria developed by a 12-person steering committee. The core authorship of the multidisciplinary EPOS 2020 guidelines was invited to participate. RESULTS: Thirty-two individuals accepted the invitation to participate and there was no dropout of participants throughout the entire study (3 rounds). Consensus essential criteria for assessment of CRS control were: overall symptom severity, need for CRS-related systemic corticosteroids in the prior 6 months, severity of nasal obstruction, and patient-reported CRS control. Near-consensus items were: nasal endoscopy findings, severity of smell loss, overall quality of life, impairment of normal activities and severity of nasal discharge. Participants’ comments provided insights into caveats of, and disagreements related to, near-consensus items. CONCLUSIONS: Overall symptom severity, use of CRS-related systemic corticosteroids, severity of nasal obstruction, and patient-reported CRS control are widely agreed upon essential criteria for assessment of CRS disease control. Consideration of near-consensus items to assess CRS control should be implemented with their intrinsic caveats in mind. These identified consensus CRS control criteria, together with evidence-based support, will provide a foundation upon which CRS control criteria with wide-spread acceptance can be developed.

The EUFOREA pocket guide for chronic rhinosinusitis.

Chronic rhinosinusitis (CRS) is known to affect around 5 % of the total population, with major impact on the quality of life of those severely affected (1). Despite a substantial burden on individuals, society and health economies, CRS often remains underdiagnosed, under-estimated and under-treated (2). International guidelines like the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) (3) and the International Consensus statement on Allergy and Rhinology: Rhinosinusitis 2021 (ICAR) (4) offer physicians insight into the recommended treatment options for CRS, with an overview of effective strategies and guidance of diagnosis and care throughout the disease journey of CRS.

Association between outdoor air pollution and chronic rhinosinusitis patient reported outcomes.

BACKGROUND: The aetiology of chronic rhinosinusitis (CRS) is multifactorial with a complex interplay between environmental, microbial endogenous and genetic factors. The impact of outdoor air pollution on prevalence or severity of CRS remains largely unknown. METHODS: Real-life geolocation data (2017-2018, Belgium) from 278 CRS patients (2576 health records) using the mySinusitisCoach mobile application were analysed to calculate the patients' individual exposure to outdoor air pollutants (ozone (O3), black carbon (BC), nitrogen dioxide (NO2) and particulate matter with diameter < 2.5 µm (PM2.5)) and to associate these pollutants with the patients' sinus related symptoms measured at multiple occasions by visual analogue scale (VAS). RESULTS: The adjusted seasonal model for the spring-summer (n = 1000 health entries, N = 83 patients) population revealed an increase of 6.07 (p < 0.0001) in overall CRS symptom scoring for an interquartile range (IQR) increase in exposure to O3 (26.9 µg/m3). An increase of 1.69 (p = 0.05) in total CRS symptom scoring was observed for an IQR increase of PM2.5 (7.1 µg/m3) exposure. Sex-stratified analysis in the spring-summer population showed significant interaction between air pollution and sex with male patients having higher total CRS symptom scores for an IQR increase in exposure to PM2.5 (3.52, p = 0.001), and O3 (8.33, p < 0.0001), while no significant association with symptom severity was seen in the female patients. In the analysis stratified by comorbid asthma, CRS patients with comorbid asthma had higher total CRS symptoms for an IQR increase in exposure to PM2.5 (2.58, p = 0.04) and O3 (7.72, p < 0.0001) while the patients without comorbid asthma had no significant symptom increases. CONCLUSION: Exposure to outdoor air pollution is associated with increased symptom severity in CRS patients. The extent to which CRS patients are sensitive to outdoor air pollution exposure varies per season and depends on their sex and comorbid asthma status. mHealth technology has the potential to reveal novel insights on the patients' exposome and disease severity in the real-life situation.

State-of-the-art overview on biological treatment for CRSwNP.

BACKGROUND: The majority of patients with uncontrolled severe CRSwNP, asthma and atopic dermatitis share a similar T helper 2 type inflammation linked to their underlying phenotype. This discovery has triggered new research around treatments targeting specific cytokines driving inflammation in CRSwNP like IL-4, IL-13, IL-5 and IgE. Biologicals are increasingly tested as additional tre- atment for patients suffering from severe chronic rhinosinusitis with nasal polyps (CRSwNP). Their efficacy has been demonstrated in multiple studies. All studies differ in terms of baseline characteristics of included patients and outcome parameters analysed. AIMS: A comparative analysis of the efficacy of reported biologicals for CRSwNP based on the published data for phase 2 and 3 studies. The aim was to provide a comprehensive overview across the different biologicals and outcome parameters. METHODS: In a first step we critically selected out of all available phase 2 and 3 clinical trials the ones containing the most rigorous and compatible study designs. Meaning studies that comply with a need for a clear definition of CRSwNP, at least two administra- tion doses, comparable timeframes and the same outcome parameters studied. This assessment was performed using a PRISMA search. We retained 7 studies with significant data for dupilumab, mepolizumab and omalizumab. In a second step the effect-sizes of treatment with those biologicals were compared for the most important outcome parameters both patient relevant (nasal con- gestion, smell loss and SNOT-22 scores) and patient irrelevant (CT scan Lund-Mackay, smell test and nasal polyp scores). Therapy duration of 16 to 25 weeks was chosen for evaluation of efficacy. RESULTS: A direct comparison of efficacy between dupilumab, mepolizumab and omalizumab is challenging given differences in inclusion criteria, outcome parameters and time-points of analyses. We have been able to conclude that effect sizes of dupilumab, mepolizumab and omalizumab seem large enough to reflect a major reduction in symptom burden as experienced by patients suffering from refractory CRSwNP. The effect size of dupilumab on both patient relevant and patient irrelevant parameters of smell loss are clearly significant and reflect the clinical experience of major reduction of smell impairment in treated patients. CONCLUSION: Despite the heterogeneity of protocols, dosages and time-points of analyses of biological trials in CRSwNP, this over- view highlights outcomes of biological treatment in CRSwNP in a comprehensive way. Real-life registries, comparative trials and/ or endotype-driven treatment plans are needed to provide the answers to the multiple questions that are still open today.

Occupational exposure influences control of disease in patients with chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is a frequent condition that is treated by endoscopic sinus surgery (ESS) when medical treatment fails. Irritating or sensitizing airborne agents can contribute to uncontrolled CRS. A prior study showed a linear correlation between occupational exposure and the number of ESS. METHODS: In this cross-sectional study we tested the hypothesis that occupational exposure is a risk for undergoing ESS. We sent questionnaires enquiring occupational exposure in patients with CRS with nasal polyps (CRSwNP) or CRS without nasal polyps (CRSsNP). An expert assessed blindly the reported work exposures to inhaled agents. The relationship between occupational exposure on undergoing ESS was analysed. RESULTS: Among all patients who underwent ESS (n=343), 30% reported a relevant occupational exposure, which is significantly higher than the 4.8% found among CRS patients that underwent no prior sinus surgery (n=21). Besides occupational exposure, self-reported doctor-diagnosed asthma were independent variables contributing to the chance of undergoing ESS. CONCLUSION: In our study we confirm occupational exposure as a risk factor for uncontrolled CRS, if defined by undergoing ESS. In CRS patients with uncontrolled symptoms, despite maximal conservative therapy, the clinician should explore the possible contribution of occupational exposure.

Dupilumab reduces systemic corticosteroid use and sinonasal surgery rate in CRSwNP.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a type 2 inflammatory disease with a high symptom burden and poor quality of life. Treatment options include recurrent surgeries and/or frequent systemic corticosteroids (SCS). Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and interleukin-13, key drivers of type 2-mediated inflammation. We report results of pooled analyses from 2 randomised, double-blind, placebo-controlled phase 3 studies (SINUS 24 [NCT02912468]; SINUS-52 [NCT02898454]) to evaluate dupilumab effect versus placebo in adults with CRSwNP with/without SCS use and sinonasal surgery. METHODOLOGY: SINUS-24 patients were randomised 1:1 to subcutaneous dupilumab 300 mg (n=143) or placebo (n=133) every 2 weeks (q2w) for 24 weeks. SINUS-52 patients were randomised 1:1:1 to 52 weeks of subcutaneous dupilumab 300 mg q2w (n=150), 24 weeks q2w followed by 28 weeks of dupilumab 300 mg every 4 weeks (n=145) or 52 weeks of placebo q2w (n=153). RESULTS: Dupilumab reduced the number of patients undergoing sinonasal surgery (82.6%), the need for in-study SCS use (73.9%), and SCS courses (75.3%). Significant improvements were observed with dupilumab vs placebo regardless of prior sinonasal surgery or SCS use in nasal polyp, nasal congestion, Lund-MacKay, and Sinonasal Outcome Test (22-items) scores, and the University of Pennsylvania Smell Identification Test. CONCLUSIONS: Dupilumab demonstrated significant improvements in disease signs and symptoms and reduced the need for sino-nasal surgery and SCS use versus placebo in patients with severe CRSwNP, regardless of SCS use in the previous 2 years, or prior sinonasal surgery.

Rhinology on the move despite Covid-19!

The October 2020 issue of Rhinology is a very interesting edition as it illustrates how world-wide colleagues pave the way for a better future of patients affected by nose and sinus diseases. After the successful launch of EPOS2020 in Spring 2020, the editorial team of Rhinology is proud to present to you the latest and most exciting data in Rhinology research. Getting insight into the complexity and relevance of proteomics in CRS, epithelial-mesenchymal contribution to CRS, zinc levels in nasal and systemic compartment of CRS, nasal biomarkers of CRSwNP that predict recurrence of disease after sinus surgery, and the odor identification test for children, called "U-Sniff", and FID scores (Frequency, Intensity and Duration) scores for epistaxis are all in the 2020 October issue and highly relevant for Rhinology practice. These studies build further on the solid grounds of previous Rhinology research meeting the unmets needs in the field.

EPOS2020 and beyond.

The April issue of Rhinology includes the Executive Summary of EPOS2020, highlighting the most important up-dates on disease definitions, treatment algorithms and integrated care pathway approaches of CRS. EPOS2020 (1) is the result of major efforts by a team of passionate rhinologists and associate health care providers coming from all corners of the world coordinated by Professors Wytske Fokkens and Valerie Lund. The Executive Summary presented here illustrates the most important graphs for use in daily practice and teaching purposes. In addition, the April issue of Rhinology also brings relevant CRS-related aspects to the attention of the readers of Rhinology.

Executive summary of EPOS 2020 including integrated care pathways.

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012(1-3). The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings.

Personal protection and delivery of rhinologic and endoscopic skull base procedures during the COVID-19 outbreak.

On March 11th 2020, the World Health Organization (WHO) declared COVID-19 pandemic, with subsequent profound impact on the entire health care system. During the COVID-19 outbreak, activities in the rhinology outpatient clinic and operation rooms are limited to emergency care only. Health care practitioners are faced with the need to perform rhinological and skull base emergency procedures in patients with a positive or unknown COVID-19 status. This article aims to provide recommendations and relevant information for rhinologists, based on the limited amount of (anecdotal) data, to guarantee high-quality patient care and adequate levels of infection prevention in the rhinology clinic.

European Position Paper on Rhinosinusitis and Nasal Polyps 2020.

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

Rhinology future trends: 2017 EUFOREA debate on allergic rhinitis.

The 2nd Rhinology Future Debate, organized by EUFOREA (European Forum for Research and Education in Allergy and Airways diseases) was held in Brussels in December 2017. One of these debates addressed the position of MP-AzeFlu in allergic rhinitis (AR) treatment. The current article summarizes this debate; reviewing recent data, and exploring how this has been interpreted by experts and incorporated into AR management guidelines and a clinical decision support system (CDSS). The Allergic Rhinitis & its Impact on Asthma (ARIA) guideline position MP-AzeFlu firstline for the treatment of AR, and in preference to intranasal corticosteroids (INSs) during the first 2 weeks of treatment. The AR CDSS recommends MP-AzeFlu as one of the firstline treatments for patients with a visual analogue scale (VAS) score lower than 5/10 cm, and in preference (along with INS) for those with a VAS score equal or higher than5/10 cm. Panellists agreed that AR management should be kept as simple as possible, with some preferring a one treatment fits all approach, while others preferred a step-up approach. The need to change the AR management mentality was acknowledged, accepting that most patients use their medication as needed and use multiple treatments; AR medications are needed which have a very fast onset of action and which target breakthrough symptoms. Panellists agreed that MP-AzeFlu has a role to play here, since it has a 5 minute onset-of-action, provides clinically-relevant symptom relief in 15 mins and AR control in less than 3 days, targets nasal hyper-reactivity (NHR) which likely contributes to uncontrolled AR and breakthrough symptoms, and provides more effective AR symptom relief than INS monotherapy or INS + oral antihistamine. Finally, experts considered it likely that MP-AzeFlu should have a greater impact on asthma control than INS in co-morbid patients, but clinical data is required to back up existing pharmacoeconomic evidence. The next Rhinology Future Debate will be in held in Brussels in Dec 2019.
