Chronic rhinosinusitis

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a chronic inflammatory disease of the nose and paranasal sinus cavities that significantly affects well-being and social function, particularly in young adults and middle-aged populations. CRSwNP is a common health condition in the Western world, with an estimated prevalence of 3%. Despite worldwide evidence-based treatment guidelines such as the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 and the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) chronic rhinosinusitis (CRS) pocket guide, a significant number of patients remain undiagnosed and/or uncontrolled with repeated oral corticosteroids (OCS) treatments and/or (multiple) endoscopic sinus surgeries (ESS)...

PURPOSE: Real-world evidence of benralizumab effectiveness on nasal polyps (NP) and asthma outcomes in patients with severe eosinophilic asthma (SEA) and comorbid chronic rhinosinusitis with NP are limited. The objective of this study was to assess NP and asthma outcomes in benralizumab-treated patients with SEA and comorbid NP in a real-world setting. PATIENTS AND METHODS: RANS was a retrospective, multi-country observational study (ClinicalTrials.gov: NCT05180357) using medical chart reviews of adults with SEA and comorbid NP...

Eosinophilic inflammation is primarily characterized by type 2 immune responses against parasitic organisms. In the contemporary human being especially in developed countries, eosinophilic inflammation is strongly associated with allergic/sterile inflammation, and constitutes an undesired immune reaction. This situation is in stark contrast to neutrophilic inflammation, which is indispensable for the host defense against bacterial infections. Among eosinophilic inflammatory disorders, massive accumulation of eosinophils within mucus is observed in certain cases, and is often linked to the distinctive clinical finding of mucus with high viscosity...

OBJECTIVE: Aim: To propose a new, original approach to assessing the quality of a multivariate regression model for predicting the risk of recurrence in patients with chronic rhinosinusitis based on ROC analysis with the construction of appropriate curves, estimating the area under them, as well as calculating the sensitivity, accuracy, specificity, and predictive value of a positive and negative classification results, the likelihood ratio of positive and negative patient detection results...

For preoperative skin antisepsis, alcohol-containing iodine solutions and octenidine are suitable. For wound antisepsis, polyhexanide and hypochlorous acid (HOCL) are also available, but only PVP-iodine and HOCL can be applied to cartilage. Chlorhexidine should only be used as mouth- and bodywash for Staphylococcus aureus (MRSA) decolonization. For the many other throat antiseptics, evidence of clinical efficacy is lacking. For decolonization of the nares, polyhexanide and octenidine are available as nasal gels, but these are inferior to mupirocin for MRSA decolonization...

BACKGROUND: Chronic Rhinosinusitis is a common disease in children. The main function of CFTR is to maintain the thickness of the mucous layer on the surface of the nasal mucosa. CFTR disease-causing variant can cause CFTR protein dysfunction and induce or aggravate chronic infection. However, the carrying status of the CFTR variants in the Chinese population is not clear. OBJECTIVE: To study the frequency and variants of CFTR in Chinese children with CRS and to analyze the CFTR variants and the clinical characteristics and susceptibility to CRS...

BACKGROUND: Studies in adult chronic rhinosinusitis (CRS) showed poor correlation between patient reported outcome measures (PROMs) and objective findings. Our goal is to study the correlation between the sinus and nasal quality of life (SN-5) and the 22-items sinonasal outcome test (SNOT-22) surveys with endoscopy findings in children with chronic adenoiditis (CA) and CRS. METHODS: Cross-sectional study of all pediatric patients (age 2-18) presenting for CA or CRS was performed...

OBJECTIVES: The purpose of this study is to investigate the lung function in Chronic Rhinosinusitis (CRS) patients with Chronic Cough (CC). METHODS: A total of 1413 CC patients were retrospectively screened and 109 CRS patients with CC were enrolled. Lung function, Lund-Mackay Computed Tomography (CT) score, smoking status, peripheral blood eosinophil count, and immunoglobulin E concentration in serum samples, and Sino-Nasal Outcome Test were examined. Normal control subjects are also recruited...

BACKGROUND: Pivotal Phase 3 trials and real-world studies have demonstrated benralizumab's overall efficacy and safety in severe eosinophilic asthma (SEA). Additional large-cohort data are needed to confirm its real-world effectiveness in SEA according to previous biologic use and key baseline characteristics important for treatment selection. METHODS: XALOC-1 is a large, multinational, retrospective, observational, real-world study programme of benralizumab in adults with SEA...

UNLABELLED: Chronic Rhinosinusitis (CRS) affects nearly 10% of the global population, leading to substantial economic and quality-of-life burdens. While patient education has improved outcomes in other chronic conditions, its impact on CRS remains understudied. The study aims to evaluate the effectiveness of a structured patient education program on the psychological well-being and symptom severity of individuals diagnosed with CRS. This was a prospective, randomized controlled trial conducted in a tertiary care centre from January 2021 to December 2022...

Diagnosis of maxillary sinus pathologies is challenging. Herewith we describe the clinicopathological features in isolated maxillary sinus lesions in tertiary care hospital in Goa, India. The retrospective study included patients treated between 2017 and 2022, of all age groups and gender, who underwent either a biopsy or surgery, providing a histopathological diagnosis. Of the 117 pathologies, 88 (75.2%) were non-neoplastic. The overall frequency of pathologies were polyp in 40.2%, fungal lesions (18.8%), malignancy (13...

Sensorineural hearing loss and chronic rhinosinusitis with nasal polyps affect a large proportion of the UK population. However, treatment with high efficacy to manage these pathologies remains to be found. With the development of biologic drug treatments, there is hope that this will improve quality of life for patients affected by these conditions. A literature review was carried out using PubMed. Studies that investigated the use of biologic drug treatment in chronic rhinosinusitis with nasal polyps, head and neck squamous cell carcinoma and sensorineural hearing loss were included in this paper...

INTRODUCTION: With a prevalence of 0.55% to 4%, chronic rhinosinusitis with nasal polyps (CRSwNP) is a relevant part of the daily work of German otolaryngologists. The aim of the questionnaire-based data collection was to assess the current treatment status of CRSwNP in Germany. MATERIAL AND METHODS: For this purpose, 24 questions within an anonymized online questionnaire were sent to all German ENT departments. RESULTS: Of 160 contacted ENT departments, 50 participated in the survey (31...

OBJECTIVES: Previously, we developed a novel double-coated sinus stent containing ciprofloxacin (inner layer) and azithromycin (outer layer) (CASS), but released drug concentrations were found to be insufficient for clinical usage. Our objectives are to improve drug release of CASS and assess safety and pharmacokinetics in rabbits. METHODS: Dip coating was used to create the CASS with 2 mg ciprofloxacin and 5 mg azithromycin. A uniformed double coating was assessed with scanning electron microscopy (SEM), and the release patterns of both drugs and lactate dehydrogenase (LDH) assay were evaluated over 14 days in vitro...

Objective: After selecting NCF2 based on bioinformatics, clinical experiments were conducted to verify the expression of NCF2 in chronic rhinosinusitis with nasal polyps to study its correlation. Methods: The differentially expressed genes（DEGs） between CRSwNP and non-CRS patients were explored using the CRS-related dataset from the gene expression omnibus GEO database. The weighted gene co-expression network（WGCNA） was used for cluster analysis. The expression and cell distribution of NCF2 in the tissues were determined by single gene enrichment analysis（GSEA）, immune inflammatory infiltration analysis, and principal component（PCA） analysis...

Background: We evaluated whether EPs® 7630 prescription in patients with acute sinusitis (AS) is associated with less frequent recurrence of AS, occurrence of chronic sinusitis or nasal polyps, or fewer antibiotic prescriptions. Methods: This retrospective cohort study used electronic medical records from the IQVIA Disease Analyzer database. Associations between initial therapy [EPs® 7630, antibiotics, intranasal corticosteroid (INCS), or corticosteroid-free nasal spray within 3 days of AS diagnosis] and AS recurrence, incidence of chronic sinusitis or nasal polyps or rate of antibiotic prescription were studied using multivariable Cox or logistic regression models, adjusting for sex, age, insurance status, month of diagnosis, and comorbidity...

PURPOSE: Severe eosinophilic asthma (SEA) patients often present overlapping inflammatory features rendering them eligible for multiple biologic therapies; switching biologic treatment is a strategy adopted to optimize asthma control when patients show partial or no response to previous biologics. PATIENTS AND METHODS: ANANKE is a retrospective, multicenter Italian study (NCT04272463). Here, we outline the characteristics and long-term clinical outcomes in naïve-to-biologics and biologics-experienced patients treated with benralizumab for up to 96 weeks...

OBJECTIVES: Prior research on olfactory dysfunction in chronic rhinosinusitis (CRS) has focused on patients with polyps and suggests that direct inflammation of the olfactory cleft mucosa plays a contributory role. The purpose of this study was to evaluate gene expression in superior turbinate mucosal specimens, comparing normosmic and dysosmic CRS patients without polyps (CRSsNP). METHODS: Tissue samples were obtained from the superior turbinates of patients with CRSsNP at the time of endoscopic sinus surgery...
