Two recent studies have highlighted the potential of nasal microbiota transplantation (NMT) to treat chronic rhinosinusitis (CRS). Here we evaluate these findings and propose that lessons from fecal microbiota transplantation (FMT) could guide NMT development, with possible implications for combating antimicrobial resistance in respiratory infections.

BACKGROUND: Pivotal studies with dupilumab demonstrated clinically relevant improvements in nasal polyp score, symptom score, and quality-of-life score in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). OBJECTIVE: We evaluated the effectiveness of dupilumab in a large-scale CRSwNP cohort from 6 European tertiary-care centers. METHODOLOGY: Nasal polyp score, Sinonasal Outcome Test 22 score, visual analog scale for total sinus symptoms, loss of smell, and nasal blockage, and Asthma Control Test (ACT) score were collected from hospital records and assessed at baseline and again at 24 and 52 weeks' treatment with dupilumab in CRSwNP patients. Treatment effectiveness was evaluated in relation to demographic and lifestyle factors, sinus surgery history, presence of comorbidities, and blood eosinophil counts (BEC). Treatment response was evaluated according to European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) 2021 criteria. RESULTS: All patient outcomes improved at 24 and 52 weeks' treatment compared to baseline. Dupilumab showed effectiveness independent of age, sex, body mass index, smoking status, prior sinus surgery, presence of asthma, nonsteroidal anti-inflammatory drug-exacerbated respiratory disease, allergy, or baseline BEC. A total of 92.5% and 94.4% showed an improvement in at least 1 EUFOREA criterion at 24 and 52 weeks, respectively; 54.4% and 68.2% met all 4 of the more stringent EUFOREA criteria at 24 and 52 weeks, respectively. CONCLUSIONS: Real-world evaluation of dupilumab effectiveness demonstrates a robust and sustained response in at least two thirds of patients at 52 weeks' treatment. Favorable treatment response was independent of the number of sinus surgery procedures, major comorbidities, or baseline systemic levels of type 2 inflammation.

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.

PURPOSE: The study analyses outcomes of the surgical treatment of odontogenic sinusitis that concurrently address sinusitis and its dental source. METHODS: A total of 364 adult patients were included, representing 13% of all patients we have operated on for any rhinosinusitis over the past 18 years. The diagnosis was based on both ENT and dental examinations including CT imaging. Patients were divided into three groups: (1) FESS with dental surgery without antrotomy, (2) FESS with intraoral antrotomy, and (3) intraoral surgery without FESS. The mean postoperative follow-up was 15 months. RESULTS: First group involved 64%, second group 31%, and third group 6% of the cases. The one-stage combined ENT and dental approach was used in 94% of cases (group 1 and 2) with a success rate of 97%. Concerning FESS, maxillary sinus surgery with middle meatal antrostomy only was performed in 54% of patients. Oroantral communication flap closure was performed in 56% of patients (success rate 98%). Healing was achieved within 3 months. The majority (87%) of patients were operated on unilaterally for unilateral findings. Over the past 18 years, a 6% increase of implant-related odontogenic sinusitis was observed. CONCLUSION: Odontogenic sinusitis is common, tending to be unilateral and chronic. Its dental source needs to be uncovered and treated and should not be underestimated. Close cooperation between ENT and dental specialists has a crucial role in achieving optimal outcomes. The one-stage combined surgical approach proves to be a reliable, safe, fast and effective treatment.

Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP) are chronic respiratory diseases. These two disorders often co-exist based on common anatomical, immunological, histopathological, and pathophysiological basis. Usually, asthma with comorbid CRSwNP is driven by type 2 (T2) inflammation which predisposes to more severe, often intractable, disease. In the past two decades, innovative technologies and detection techniques in combination with newly introduced targeted therapies helped shape our understanding of the immunological pathways underlying inflammatory airway diseases and to further identify several distinct clinical and inflammatory subsets to enhance the development of more effective personalized treatments. Presently, a number of targeted biologics has shown clinical efficacy in patients with refractory T2 airway inflammation, including anti-IgE (omalizumab), anti-IL-5 (mepolizumab, reslizumab)/anti-IL5R (benralizumab), anti-IL-4R-α (anti-IL-4/IL-13, dupilumab), and anti-TSLP (tezepelumab). In non-type-2 endotypes, no targeted biologics have consistently shown clinical efficacy so far. Presently, multiple therapeutical targets are being explored including cytokines, membrane molecules and intracellular signalling pathways to further expand current treatment options for severe asthma with and without comorbid CRSwNP. In this review, we discuss existing biologics, those under development and share some views on new horizons.

BACKGROUND: Real-world evidence (RWE) is a valuable instrument to better understand the patient journey and effectiveness of therapies. RWE on the prevalence of uncontrolled chronic rhinosinusitis (CRS) and CRS natural course of disease across Europe is scarce. In addition, there is limited RWE that enables comparison of the effectiveness of marketed therapies including topical or systemic corticosteroids, sinus surgery, or biologics. OBJECTIVE: To establish an international CHRonic rhINOSinusitis Outcome Registry (CHRINOSOR) based on real-world data collection enabled by mobile health technology. METHODOLOGY: A digital platform, Galenus Health, supporting patients and physicians in the management of chronic respiratory diseases, is used to collect data on patient profile, disease history, patient outcomes, and a set of relevant clinical outcomes. Adult patients with a diagnosis of CRS are eligible for inclusion. RESULTS: A collaborative scientific network of 17 university ear-nose-throat (ENT) clinics from 10 European countries has been established with the aim to collect real-world data in a longitudinal and standardized manner. The Galenus Health digital platform is currently being implemented in these ENT clinics taking into account legal, privacy, and data security aspects. Up to 300 patients have already been included. CONCLUSIONS: CHRINOSOR is a collaborative effort that aims at improving our understanding of CRS, its comorbidities, and the effectiveness of its treatments. Ultimately, these insights will guide us as scientific community to develop future care pathways informed by RWE.

PURPOSE: Recently, a new CT scan classification of the extent of previous endoscopic sinus surgery called The Amsterdam Classification of Completness of Endoscopic Sinus Surgery (ACCESS) was published. The aim of this study was to investigate possible associations between traditionally used Lund-Mackay CT score and ACCESS score and their possible relationship to pre- and postoperative quality of life in a narrowly defined group of patients with recurrent CRSwNP. METHODS: Forty-nine patients who underwent a revision ESS for CRSwNP were enrolled in a retrospective study. CT imaging scans were evaluated, LM and ACCESS scores determined. All patients completed the validated Czech version of the SNOT-22 questionnaire before and 6 months after surgery. The correlation between the two CT scores and the QoL questionnaire was tested using Pearson's correlation tests. RESULTS: No correlation was demonstrated between LM scores and patient-based SNOT-22 scores neither preopratively nor postoperatively (r = - 0.0580; p = 0.918 and r = 0.0252; p = 0.8634, respectively. Similarly, no correlation was found between the ACCESS score and SNOT-22 before and after surgery (r = - 0.1988; p = 0.1708 and r = - 0.943; p = 0.5193, respectively). No linear relationship was demonstrated between the LM score and the ACCESS score (r = 0.075; p = 0.6053). CONCLUSIONS: The results show that even the CT score evaluating the completeness of previous procedures has no linear relationship to the quality of life preoperatively and cannot serve as a predictor for the outcomes of surgical treatment. This study also confirms that ACCESS evaluates a different aspect of the radiological finding than the traditionally used LM score.

Although extensive research has shown the pathological effect of fine and ultrafine airborne particles, clear evidence of association of environmental exposure to them and inflammatory changes in human nasal mucosa is missing. Meanwhile, pathogenesis of chronic rhinosinusitis, despite being a disease with high prevalence in the population, is still unclear. The increasing evidence of the pro-inflammatory properties of these particles raises the question of their possible role in chronic rhinosinusitis. The presented study focused on detection of microsized anorganic particles and clusters of nanosized anorganic particles in the nasal mucosa of patients with chronic rhinosinusitis by Raman microspectroscopy and comparison of their composition to histologic findings. The results were compared to the findings in mucosa obtained from cadavers with no history of chronic rhinosinusitis. Solid particles were found in 90% of tissue samples in the group with chronic rhinosinusitis, showing histologic signs of inflammation in 95%, while in the control group, the particles were found in 20% of samples, with normal histologic findings in all of them. The main detected compounds were graphite, TiO2, amorphous carbon, calcite, ankerite and iron compounds. The results are in accordance with the premise that exogenous airborne particles interact with the nasal mucosa and possibly deposit in it in cases where the epithelial barrier is compromised in chronic rhinosinusitis.

BACKGROUND: Loss of smell (LoS) is one of the most troublesome and difficult-to-treat symptoms of severe chronic rhinosinusitis with nasal polyps (CRSwNP). OBJECTIVE: To assess the impact of dupilumab on sense of smell in severe CRSwNP. METHODS: In the randomized SINUS-24 and SINUS-52 studies, adults with severe CRSwNP received dupilumab 300 mg subcutaneously or matching placebo every 2 weeks for 24 or 52 weeks, respectively. Smell was assessed using daily patient-reported LoS score (0-3) and University of Pennsylvania Smell Identification Test (UPSIT; 0-40). Data from the 2 studies were pooled through week 24. Relationships between patient phenotypes and smell outcomes were also assessed. RESULTS: We randomized 724 patients (286 placebo, 438 dupilumab); mean CRSwNP duration was 11 years; 63% had prior sinonasal surgery. Mean baseline LoS was 2.74. Dupilumab produced rapid improvement in LoS, evident by day 3, which improved progressively throughout the study periods (least squares mean difference vs placebo -0.07 [95% CI -0.12 to -0.02]; nominal P < .05 at day 3, and -1.04 [-1.17 to -0.91]; P < .0001 at week 24). Dupilumab improved mean UPSIT by 10.54 (least squares mean difference vs placebo 10.57 [9.40-11.74]; P < .0001) at week 24 from baseline (score 13.90). Improvements were unaffected by CRSwNP duration, prior sinonasal surgery, or comorbid asthma and/or nonsteroidal anti-inflammatory drug-exacerbated respiratory disease. Baseline olfaction scores correlated with all measured local and systemic type 2 inflammatory markers except serum total immunoglobulin E. CONCLUSIONS: Dupilumab produced rapid and sustained improvement in sense of smell, alleviating a cardinal symptom of severe CRSwNP.

BACKGROUND: Rhinosinusitis is an inflammation of the sinonasal cavity which affects roughly one in seven people per year. Acute rhinosinusitis (ARS) is mostly, apart from allergic etiology, caused by a viral infection and, in some cases (30-50%), by a bacterial superinfection. Antibiotics, indicated only in rare cases according to EPOS guidelines, are nevertheless prescribed in more than 80% of ARS cases, which increases the resistant bacterial strains in the population. METHODS: We have designed a clinical decision support system (CDSS), RHINA, based on a web application created in HTML 5, using JavaScript, jQuery, CCS3 and PHP scripting language. The presented CDSS RHINA helps general physicians to decide whether or not to prescribe antibiotics in patients with rhinosinusitis. RESULTS: In a retrospective study of a total of 1465 patients with rhinosinusitis, the CDSS RHINA presented a 90.2% consistency with the diagnosis and treatment made by the ENT specialist. CONCLUSION: Patients assessed with the assistance of our CDSS RHINA would decrease the over-prescription of antibiotics, which in turn would help to reduce the bacterial resistance to the most commonly prescribed antibiotics.
