Objective: To evaluate the impact of obstructive sleep apnea (OSA) on the quality-of-life (QoL) of patients with chronic rhinosinusitis (CRS)., Methods: Retrospective cohort study of all adult patients with CRS presenting to our rhinology clinic between August 2020 and February 2023 was performed. OSA was established based on positive polysomnography. Patients' characteristics, apnea-hypopnea index, comorbidities, endoscopy scores, and SNOT-22 scores were collected., Results: A total of 513 patients with CRS were included, 127 patients with OSA and 386 without OSA. CRS patients with OSA were older (p < 0.001), had higher BMI (p < 0.001), more likely to be males (p = 0.07), more likely to have asthma (p < 0.001), and more likely to have COPD (p = 0.001). Presence of nasal polyps did not differ between the two groups. Baseline SNOT-22 scores were worse in the OSA cohort (44.4 vs 40.5, p = 0.064) secondary to worse sleep (13.4 vs 11.1; p = 0.002) and psychological (14.2 vs 11.5; p = 0.002) domains. Worse SNOT scores were strongly associated with presence of OSA after adjusting for confounding variables, including age, gender, asthma, allergic rhinitis, nasal septal deviation, and smoking status., Conclusion: OSA is an independent negative contributor to the disease specific QoL in patients with CRS. CPAP use does not seem to affect the QoL in CRS patients with OSA. Further research is warranted to explore the impact of OSA in the outcome of medical and surgical treatment of CRS patients., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Purpose: Asthma, obstructive sleep apnea (OSA), rhinosinusitis, and esophageal reflux are conditions that may overlap, forming a syndrome known as CORE. Whenever clinical remission of severe asthma (SA) is not achieved, it is essential to investigate the presence of comorbidities, in particular the presence of OSA that may lead to the diagnosis of CORE syndrome., Methods: The study was conducted on naive patients with SA and concomitant rhinosinusitis and esophageal reflux, referred to our institute since 2018. Patients who did not experience clinical remission were investigated for OSA through a home sleep apnea test. Subsequently, for those diagnosed with OSA, continuous positive airway pressure (CPAP) was proposed and was re-evaluated after 12 months., Results: Six patients with CORE syndrome were enrolled. The mean apnea-hypopnea index (AHI) was 33.25 ± 20.13 events/h, oxygen desaturation index (ODI) was 28.95 ± 19.95 events/h, and time in bed with SaO2 < 90% (T 90 ) was 26.40 ± 27.22% for which continuous positive airway pressure (CPAP) treatment was proposed but only 3 out of 6 patients accepted. After 12 months, all CPAP-treated patients manifested a significant reduction in daytime sleepiness (ESS score was 6.33 ± 3.8), an improvement in ACT score (+ 8 (+ 32%), + 9 (+ 36%), and + 14 (+ 56%) points), a discontinuation of oral corticosteroids (OCS), an absence of exacerbations, and an improvement of lung function leading to clinical remission of asthma., Conclusion: Whenever facing SA patients, non-responders to therapy, it is important to suspect the presence of CORE syndrome; in particular, the detection and subsequent treatment of OSA would seem to improve the outcome of such patients., (© 2024.

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major differences in indications, outcomes, practical considerations, risks and costs of these key pillars of treatment, there is a growing need to define criteria for each treatment option and list the clinically relevant and major considerations for them. This EUFOREA document therefore provides an expert panel overview of the expected outcomes, specific considerations and (contra)indications of the five major treatment arms of severe uncontrolled CRSwNP: oral corticosteroids, primary and revision sinus surgery, biological treatment and ATAD. This overview of treatment considerations is needed to allow physicians and patients to consider the different options in the context of providing optimal and personalized care for severe uncontrolled CRSwNP. In conclusion, the five major treatment options for severe uncontrolled CRSwNP have intrinsic advantages, specific indications and considerations that are of importance to the patient, the physician and the society. This EUFOREA statement supports the unmet need to define criteria for the indication of every treatment pillar of CRSwNP., (© 2023 The Authors.

Tight junction (TJ) proteins establish a physical barrier between epithelial cells, playing a crucial role in maintaining tissue homeostasis by safeguarding host tissues against pathogens, allergens, antigens, irritants, etc. Recently, an increasing number of studies have demonstrated that abnormal expression of TJs plays an essential role in the development and progression of inflammatory airway diseases, including chronic obstructive pulmonary disease, asthma, allergic rhinitis, and chronic rhinosinusitis (CRS) with or without nasal polyps. Among them, CRS with nasal polyps is a prevalent chronic inflammatory disease that affects the nasal cavity and paranasal sinuses, leading to a poor prognosis and significantly impacting patients' quality of life. Its pathogenesis primarily involves dysfunction of the nasal epithelial barrier, impaired mucociliary clearance, disordered immune response, and excessive tissue remodeling. Numerous studies have elucidated the pivotal role of TJs in both the pathogenesis and response to traditional therapies in CRS. We therefore to review and discuss potential factors contributing to impair and repair of TJs in the nasal epithelium based on their structure, function, and formation process., (© 2024 The Authors.

Background: Existing patient-reported outcome measures (PROMs) for chronic rhinosinusitis (CRS) use a variety of recall periods and response scales to assess CRS symptom burden. Global perspectives of CRS patients regarding optimal recall periods and response scales for CRS PROMs are unknown., Methods: This was a multi-center, cross-sectional study recruiting 461 CRS patients from sites across the United States, Saudi Arabia, New Zealand, and Austria. Participants chose which CRS symptom recall period (1 day, 2 weeks, 1 month, >1 month) was most reflective of their current disease state and upon which to best base treatment recommendations (including surgery). Participants also chose which of six response scales (one visual analogue scale and five Likert scales ranging from four to eight items) was easiest to use, understand, and preferred., Results: A plurality of participants (40.0%) felt their CRS symptoms' current state was best reflected by a 1-month recall period. However, most patients (56.9%) preferred treatment recommendations to be determined by symptoms experienced over a >1 month period. The four- and five-item Likert scales were the easiest to understand (26.0% and 25.4%, respectively) and use (23.4% and 26.7%, respectively). The five-item (26.4% rating it most preferred and 70.9% rating it preferred) and four-item Likert (22.3% rating it most preferred and 56.4% rating it preferred) response scales were most preferred., Conclusion: Future PROMs for CRS should consider assessment of symptoms over a 1-month period and use a four- or five-item Likert response scale to reflect global patient preferences. These findings also inform interpretation of current CRS PROMs., (© 2023 The Authors.

Objective: To determine the structure and nature of headache in pediatric patients, as well as its relationship with chronic rhinosinusitis, to develop an effective rehabilitation course for pediatric patients with headache at the sanatorium-resort stage., Material and Methods: The study included 100 patients aged 8 to 17 years who received a course of sanatorium treatment. Patients were divided into groups: with primary headache and with secondary headache in chronic rhinosinusitis., Results: The results of a comprehensive otorhinolaryngological and neurological study made it possible to determine the mechanism of development, structure, and nature of the predominant types of headache in children and to develop a course of rehabilitation treatment. An analysis of the effectiveness of the rehabilitation course showed that it was possible to achieve a positive result in 88% of children with primary and secondary headache. The necessity of interdisciplinary participation of otorhinolaryngologists and neurologists in the examination and treatment of patients complaining of headache at the sanatorium-resort stage is substantiated., Conclusion: The effectiveness of the proposed rehabilitation course of headache treatment of various origins in children has been proven, the analysis of long-term results allows us to recommend it during staged therapy.

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