GG in a chewable colonizes the nose and facilitates local immune benefits in allergic rhinoconjunctivitis patients.

Current treatments fall short in managing allergic rhinitis (AR), emphasizing the need for additional strategies. Beneficial bacteria application shows promise in AR; however, most studies focus on oral probiotic administration without monitoring the applied strains in the upper respiratory tract (URT) and their local effects. In this randomized, double-blind, placebo-controlled trial, the probiotic GG was administered via chewable tablets in seasonal AR patients, randomized to probiotic ( = 33) or placebo ( = 31) groups.

Characterization of Chronic Rhinosinusitis Patients Based on Markers of Type 2 Inflammation: Findings From the European CRS Outcome Registry (CHRINOSOR).

Background: Primary chronic rhinosinusitis (CRS) can be classified based on the sinuses involved and the dominant endotype of the mucosal inflammation. Since the introduction of type 2 targeted biologics as treatment option for CRS, assessment of the inflammatory status has gained importance in CRS patients. We here aimed to characterize CRS patients with and without elevated markers of type 2 inflammation.

Validation of the Skin Prick Automated Test (SPAT) Cut-Off Value in Birch Pollen and House Dust Mite Allergic Rhinitis Patients.

Introduction: A novel device, Skin Prick Automated Test (SPAT), previously showed reduced variability and more consistent test results compared to conventional skin prick test (SPT) to identify allergic sensitisation. This study aimed to clinically validate the adjusted SPAT cut-off in patients with confirmed birch or house dust mite (HDM) allergy.

Methods: Seventy-five adults were included: 25 non-allergic subjects (confirmed by lack of allergy history and negative SPT), 25 birch and 25 HDM allergic rhinitis patients (both confirmed by positive SPT and nasal allergen challenge [NAC]).

Radiological score, asthma and NSAID-exacerbated respiratory disease predict relapsing chronic rhinosinusitis.

Objectives: The aim was to evaluate the predictive potential of Sinonasal Radiological (SR) and the Lund-Mackay (LM) score of sinus computed tomography (CT) scans on postoperative relapses of chronic rhinosinusitis (CRS).

Materials And Methods: CRS patients (n = 483, 12-80 years) underwent routine sinus CT scans. The SR score was defined by obstructed frontal recess (0 = no, 1 = yes) and visualization of middle and inferior turbinate (0 = anatomy can be easily visualized, 1 = anatomy cannot be easily visualized) on each side (a total of 0-6 points).

Chronic rhinosinusitis with nasal polyps: Key considerations in the multidisciplinary team approach.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a recurrent inflammatory disease associated with several comorbidities and a significant disease burden for patients. Treatments include corticosteroids and sinonasal surgery, but these can be associated with the risk of adverse events and nasal polyp recurrence. Biologic treatments such as mepolizumab can be used as an add-on treatment and are effective at reducing surgery and corticosteroid use.

Promoting Prevention and Targeting Remission of Asthma: A EUFOREA Consensus Statement on Raising the Bar in Asthma Care.

Asthma is a common, multifaceted respiratory disease with a major impact on quality of life. Despite increased insights into mechanisms underlying various asthma phenotypes and endotypes and the availability of targeted biologic treatment options, the disease remains uncontrolled in a substantial proportion of patients with risk of exacerbations, requiring systemic corticosteroids, and with progressive disease. Current international guidelines advocate for a personalized management approach to patients with uncontrolled severe asthma.

Thymic Stromal Lymphopoietin (TSLP): Evidence in Respiratory Epithelial-driven Diseases Including Chronic Rhinosinusitis with Nasal Polyps.

Purpose Of The Review: Thymic stromal lymphopoietin (TSLP) is increasingly recognized for its pivotal role in the pathogenesis of various epithelial-driven chronic inflammatory diseases. This review navigates the existing evidence on TSLP, with a particular focus on asthma, before delving into the current understanding of its role in chronic rhinosinusitis with nasal polyps (CRSwNP). We explore the role of TSLP in the pathogenesis of asthma and CRSwNP, two conditions often interconnected and collectively referred to as"Global Airway Disease".

Rare presence and function of neuroendocrine cells in the nasal mucosa.

There is growing evidence that neurogenic inflammation contributes to the pathophysiology of upper airway diseases, with nasal hyperreactivity (NHR) being a key symptom. The rare neuroendocrine cells (NECs) in the epithelium have been linked to the pathophysiology of bronchial and intestinal hyperreactivity, however their presence in the nasal mucosa and their potential role in NHR remains unclear. Therefore, we studied the presence of NECs in the nasal epithelium of controls, allergic rhinitis patients and chronic rhinosinusitis with nasal polyps patients, and their link to NHR.

Dupilumab response onset, maintenance, and durability in patients with severe CRSwNP.

Background: Responder analyses of SINUS phase 3 study data have shown clinically meaningful improvements across multiple outcomes of treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) with dupilumab.

Objective: Our aim was to gain a better understanding of dynamics of the response to dupilumab over 52 weeks.

Methods: We used data from the SINUS-52 (ClinicalTrials.

EUFOREUM Berlin 2023: Optimizing care for type 2 inflammatory diseases from clinic to AI: A pediatric focus.

The European Forum for Research and Education in Allergy and Airways diseases (EUFOREA) organized its bi-annual forum EUFOREUM in Berlin in November 2023. The aim of EUFOREUM 2023 was to highlight pediatric action plans for prevention and optimizing care for type 2 inflammatory conditions starting in childhood, with a focus on early-stage diagnosis, ensuring neither under- nor overdiagnosis, optimal care, and suggestions for improvement of care. EUFOREA is an international not-for-profit organization forming an alliance of all stakeholders dedicated to reducing the prevalence and burden of chronic respiratory diseases through the implementation of optimal patient care via educational, research, and advocacy activities.

The nasal basal cell population shifts toward a diseased phenotype with impaired barrier formation capacity in allergic rhinitis.

Background: The integrity of the airway epithelium is guarded by the airway basal cells that serve as progenitor cells and restore wounds in case of injury. Basal cells are a heterogenous population, and specific changes in their behavior are associated with chronic barrier disruption-mechanisms that have not been studied in detail in allergic rhinitis (AR).

Objective: We aimed to study basal cell subtypes in AR and healthy controls.

Clinical benefits with 300 IR HDM SLIT tablet in Europeans with house dust mite allergic rhinitis: Post hoc analysis of a large phase 3 trial.

Background: House dust mite (HDM)-induced allergic rhinitis (AR) is a major cause of allergic respiratory disease. The efficacy and safety of the 300 IR HDM sublingual immunotherapy (SLIT) tablet in patients with moderate-to-severe HDM-AR was confirmed in a large, international, phase 3 randomized controlled trials (RCTs). Here, we analyzed the results in the European population.

Nasal Obstruction: Overview of Pathophysiology and Presentation of a Clinically Relevant Preoperative Plan for Rhino(Septo)plasty.

Impairment of nasal breathing is a highly prevalent and bothersome symptom that affects daily functioning and/or sleep quality. Those surgeons dealing with patients seeking rhinoplasty need to carefully analyze the preoperative nasal breathing capacity and predict the positive or even negative impact of rhino(septo)plasty on nasal breathing. Given the lack of correlation between the subjective feeling of suboptimal nasal breathing and the objective measurements of nasal flow and nasal resistance, a critical and mainly clinical evaluation of all anatomical, mucosal, and sensory mechanisms involved in nasal obstruction is mandatory.

EUFOREA/EPOS2020 statement on the clinical considerations for chronic rhinosinusitis with nasal polyps care.

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.

Evaluation of skin prick location on the forearm using a novel skin prick automated test device.

Background: The skin prick test (SPT) is the gold standard for identifying allergic sensitization in individuals suspected of having an inhalant allergy. Recently, it was demonstrated that SPT using a novel skin prick automated test (SPAT) device showed increased reproducibility and tolerability compared to the conventional SPT, among other benefits.

Objective: This study aimed to evaluate prick location bias using the novel SPAT device.

Sustained efficacy of mepolizumab in patients with severe chronic rhinosinusitis with nasal polyps: SYNAPSE 24-week treatment-free follow-up.

Background: In the 52-week Phase III SYNAPSE study, mepolizumab given every 4 weeks (100 mg subcutaneously) reduced nasal polyp (NP) size, improved symptoms and quality of life (QoL), and reduced corticosteroid use and number of sinus surgeries in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP), versus placebo. Because the durability of mepolizumab's efficacy after discontinuation is poorly understood in CRSwNP, the efficacy of mepolizumab after discontinuation was analyzed in severe CRSwNP, over a 24-week follow-up.

Methods: Changes from SYNAPSE baseline to end of treatment (week 52) and end of follow-up (week 76) were assessed for total endoscopic NP score, nasal obstruction and overall symptoms visual analog scale scores, and 22-item Sino-Nasal Outcome Test score.

The Management of Chronic Rhinosinusitis With Nasal Polyps (CRSwNP) With Biologics.

Chronic rhinosinusitis with nasal polyps affects a significant portion of the worldwide population. This illness is associated with several chronic conditions and has an important impact on patient quality of life, leading to a great societal economic burden. In recent years, biologic medications have been developed and found to be effective in the treatment of chronic rhinosinusitis with nasal polyps.

Monoclonal antibody or aspirin desensitization in NSAID-exacerbated respiratory disease (N-ERD)?

Nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) is a clinical syndrome characterized by nasal polyposis, asthma, and intolerance to aspirin/NSAID. It affects approximately 15% cases of severe asthma, 10% of nasal polyps and 9% of rhinosinusitis. N-ERD results in associated asthma exacerbations, oral corticosteroids bursts, corticosteroid-dependent disease, and multiple endoscopic sinus surgeries.
