Dual and triple modulator therapy for chronic rhinosinusitis in cystic fibrosis patients.

BACKGROUND: The introduction of CFTR modulators has changed the landscape in the treatment of cystic fibrosis (CF) and early case series have shown improvements in sinonasal outcomes in this patient population. METHODOLOGY: A real-word data study was performed to evaluate the impact of dual therapy with tezacaftor/ivacaftor (TEZ/IVA) and triple therapy with elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) on CF-related chronic rhinosinusitis (CRS), by comparing subjective and objective outcome measures at baseline, 12 months after treatment with TEZ/IVA and six months after treatment with ELX/TEZ/IVA. RESULTS: In total, 43 CF patients, with a mean age of 32 years, were included. After triple therapy, significant improvements in overall visual analogue scale, SNOT-22, Lund Kennedy, nasal polyps, and Lund-Mackay scores were observed, whereas no beneficial effect could be seen in patients treated with dual therapy. Bacterial upper airway colonization did not differ pre- and postmodulator therapy in the present study. The number of responders to dual and triple therapy is 23.8% and 63.2% of the patients, respectively. CONCLUSIONS: Triple therapy with ELX/TEZ/IVA is superior to dual therapy with TEZ/IVA in the treatment of CF-CRS, as significantly reduced sinonasal complaints, nasal endoscopy and CT scores were observed after triple therapy, whereas this was not the case for dual therapy.

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 (p.

Skin Prick Automated Test device offers more reliable allergy test results compared to a manual skin prick test.

BACKGROUND: The skin prick test (SPT) is the gold standard for identifying allergic sensitization in individuals suspected of inhalant allergy. A novel device, SPAT or Skin Prick Automated Test, that enables more standardized allergy testing has been developed. Previous research has shown reduced intra-subject variability of histamine wheals by SPAT. OBJECTIVE: This study aimed to evaluate within-test agreement (% of patients with consistent test results) to detect sensitization to common inhalant allergens when a SPT is executed automated by SPAT or by manual SPT (SPMT) procedure. METHODS: The 110 volunteers prospectively enrolled underwent both SPAT and SPMT with 3 pricks of house dust mite, timothy grass and birch, 2 pricks of histamine and 1 prick of glycerol. The proportion of consistent (3x positive â€" 3 x negative) and inconsistent (2x positive/negative â€" 1x positive/negative) test results were analysed. RESULTS: The proportion of inconsistent test results was significantly lower in the SPAT compared to the SPMT group. The delta histamine to control pricks was significantly higher in SPAT compared to SPMT group. Coefficient of variation was lower in SPAT compared to SPMT for house dust mite, timothy grass, birch pollen. Visual analogue scale for discomfort was significantly lower in SPAT compared to SPMT group. CONCLUSION: SPAT showed a 34% reduction in the number of inconsistent test results compared to manual SPT with common inhalant allergens. Patient experience is significantly improved when an allergy test is performed by SPAT compared to a manual SPT.

Position paper on olfactory dysfunction: 2023

BACKGROUND: Since publication of the original Position Paper on Olfactory Dysfunction in 2017 (PPOD-17), the personal and societal burden of olfactory disorders has come sharply into focus through the lens of the COVID-19 pandemic. Clinicians, scientists and the public are now more aware of the importance of olfaction, and the impact of its dysfunction on quality of life, nutrition, social relationships and mental health. Accordingly, new basic, translational and clinical research has resulted in significant progress since the PPOD-17. In this updated document, we present and discuss currently available evidence for the diagnosis and management of olfactory dysfunction. Major updates to the current version include, amongst others: new recommendations on olfactory related terminology; new imaging recommendations; new sections on qualitative OD and COVID-19 OD; updated management section. Recommendations were agreed by all co-authors using a modified Delphi process. CONCLUSIONS: We have provided an overview of current evidence and expert-agreed recommendations for the definition, investigation, and management of OD. As for our original Position Paper, we hope that this updated document will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency, and generalisability of work in this field.

The intranasal trigeminal system: roles in rhinitis (allergic and non-allergic).

The aim of this paper is to review intranasal trigeminal system and associated reflexes. The literature survey was performed on PubMed, ProQuest Central database of Kirikkale University and Google Scholar. The intranasal trigeminal system and associated reflexes play an important role in humans in both health and disease, including in rhinitis of non-allergic and mixed type. The intranasal trigeminal nerve provides sensory perception to the lining of the nose, supplying information on how patent the nasal airway is and responding to various chemical signals. The reflexes known to exist within the intranasal trigeminal system are nasobronchial reflex, trigemino-cardiac reflex, nasogastric reflex, and nasal cycle. The intranasal trigeminal system and its reflexes play a vital role in normal human physiology. Alterations in how this system operates may underlie multiple forms of rhinitis and more research is needed to fully understand the mechanisms involved.

Predicting postoperative complications and their impact on quality of life and functional status in older patients with breast cancer.

BACKGROUND: The percentage of older patients undergoing surgery for early-stage breast cancer has decreased over the past decade. This study aimed to develop a prediction model for postoperative complications to better inform patients about the benefits and risks of surgery, and to investigate the association between complications and functional status and quality of life (QoL). METHODS: Women aged at least 70 years who underwent surgery for Tis-3 N0 breast cancer were included between 2013 and 2018. The primary outcome was any postoperative complication within 30 days after surgery. Secondary outcomes included functional status and QoL during the first year after surgery, as assessed by the Groningen Activity Restriction Scale and the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23 questionnaires. A prediction model was developed using multivariable logistic regression and validated externally using data from the British Bridging the Age Gap Study. Linear mixed models were used to assess QoL and functional status over time. RESULTS: The development and validation cohorts included 547 and 2727 women respectively. The prediction model consisted of five predictors (age, polypharmacy, BMI, and type of breast and axillary surgery) and performed well in internal (area under curve (AUC) 0.76, 95 per cent c.i. 0.72 to 0.80) and external (AUC 0.70, 0.68 to 0.72) validations. Functional status and QoL were not affected by postoperative complication after adjustment for confounders. CONCLUSION: This validated prediction model can be used to counsel older patients with breast cancer about the postoperative phase. Postoperative complications did not affect functional status nor QoL within the first year after surgery even after adjustment for predefined confounders.

Surgery remains the standard of care for the majority of older patients with breast cancer. The percentage of older patients with breast cancer receiving surgery is decreasing. The reason for this decline is unknown, but it might be due to fear of complications. To better inform patients about the benefits and risks of surgery, the aim of this study was to develop a prediction model for complications after surgery. Another important aspect, especially for older adults with breast cancer, is quality of life, functional capacity, and ability to carry out daily tasks (functional status) after therapy. This study showed that quality of life and functional status did not decline after breast surgery, irrespective of the occurrence of postoperative complications.

Positive health during the COVID-19 pandemic: a survey among community-dwelling older individuals in the Netherlands.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) reached the Netherlands in February 2020. To minimize the spread of the virus, the Dutch government announced an "intelligent lockdown". Older individuals were urged to socially isolate completely, because they are at risk of a severe disease course. Although isolation reduces the medical impact of the virus, the non-medical impact should also be considered. AIM: To investigate the impact of COVID-19 pandemic and associated restrictive measures on the six dimensions of Positive Health in community-dwelling older individuals living in the Netherlands, and to identify differences within subgroups. METHODS: In May/June 2020, community-dwelling older individuals aged ≥ 65 years completed an online survey based on Huber's model of Positive Health. Positive Health was measured regarding the appreciation of the six dimensions (categorized as poor/satisfactory/excellent) and a comparison with a year before (categorized as decreased/unchanged/increased) using frequencies (%) and a chi-square test. RESULTS: 834 older individuals participated (51% women, 38% aged ≥ 76 years, 35% living alone, 16% self-rated poor health). Most respondents assessed their bodily functions, mental well-being and daily functioning as satisfactory, their meaningfulness and quality of life (QoL) as excellent, and their social participation as poor. 12% of the respondents reported a deterioration of 4-6 dimensions and 73% in 1-3 dimensions, compared to the past year. Deterioration was most frequently experienced in the dimension social participation (73%), the dimension mental well-being was most frequently improved (37%) and quality of life was in 71% rated as unchanged. Women more often observed a deterioration of 4-6 dimensions than men (15% vs. 8%, p = 0.001), and individuals with self-rated poor health more often than individuals with self-rated good health (22% vs. 10%, p < 0.001). Older individuals living alone experienced more frequently a decrease in meaningfulness compared to older individuals living together. CONCLUSION: The COVID-19 pandemic and associated restrictive measures had a substantial impact on all six dimensions of Positive Health in community-dwelling older individuals, especially in women, respondents living alone and respondents with self-rated poor general health.

EPOS 4 Patients.

EPOS2020 is the 4th and most recent version of the European Position Paper on Rhinosinusitis and Nasal Polyps which was first published in 2005. It aims to provide the most up to date scientifically robust information on the topic published in the literature which has been critically analysed by an international group of clinicians drawn from all disciplines dealing with these problems together with patients. The guidelines offer evidence-based recommendations and care pathways for acute and chronic rhinosinusitis in both adults and children. Management of these diseases from the patients' perspective is an important part of EPOS2020. Not only is this included in the main document but, for the first time, we have produced a separate supplement dedicated to and in collaboration with patients, EPOS4Patients, which aims to provide information in an accessible format, to answer frequently asked questions about these diseases and their treatment options as well as including useful patient resources and websites. It has never been more important for patients to be actively involved in their care. Being well informed helps you to make the best decisions together with your doctor.

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.

Stepwise approach towards adoption of allergen immunotherapy for allergic rhinitis and asthma patients in daily practice in Belgium: a BelSACI-Abeforcal-EUFOREA statement.

Allergic rhinitis (AR) affects 23-30% of the European population with equal prevalence reported in Belgium. Despite guidelines on the correct use of effective treatment, up to 40% of AR patients remain uncontrolled. Allergen immunotherapy (AIT) has been shown to improve the level of control up to 84% of patients being controlled by AIT. Recently, new guidelines for AIT have been published, supporting the clinical evidence for effectiveness of various subcutaneous and sublingual products for AIT in patients who are allergic to airborne allergens. AIT in AR patients not only reduces nasal and/or ocular symptoms but also induces tolerance and has preventive potential. Adoption of AIT into daily clinical practice in Belgium and other European countries is hampered primarily by reimbursement issues of each of the single products but also by several patient- and physician-related factors. Patients need to be better informed about the effectiveness of AIT and the different routes of administration of AIT. Physicians dealing with AR patients should inform patients on tolerance-inducing effects of AIT and are in the need of a harmonized and practical guide that supports them in selecting eligible patients for AIT, in choosing evidence-based AIT products and in following treatment protocols with proven efficacy. Therefore, a stepwise and holistic approach is needed for better adoption of AIT in the real-life setting in Belgium.

Modified nasal floor and inferior meatus flap for septal perforation repair. Extension and limits.

BACKGROUND: The nasal floor and inferior meatus (NFIM) flap represents an available option for the reconstruction of a septal perforation (SP). This study explores the feasibility of repairing SPs using a modified simple and extended (including inferior turbinate) NFIM flap. METHODS: An anatomic study was achieved in fresh frozen cadaveric specimens to measure the area and lengths of NFIM flap. The repair of SP with simple and extended NIFM flaps was performed in some of these cadaveric specimens. Preoperative radiological evaluation of CT scans allowed studying the reconstruction limits of the simple or extended NFIM flap. A cohort of patients with SP who underwent reconstruction with an NFIM flap was also included. RESULTS: Complete SP repair with NFIM was achieved in all specimens (n=10). In 38 fresh cadaveric specimens, coronal and sagittal lengths and area of simple NFIM flaps were smaller than in extended NFIM flaps. The radiological analysis of 75 CT scans revealed that the septal height could be reconstructed with a simple and extended NFIM flap. Complete SP repair wasachieved in 5 patients (4 male, mean age 57.4 years) using modified NFIM flaps. CONCLUSION: The simple or expanded NFIM flap represents a feasible option to repair small or medium-sized perforations located at the lower 1/3 or 3/4 of the nasal septum.

Nasal hyperreactivity in rhinitis: A diagnostic and therapeutic challenge.

Although nasal hyperreactivity (NHR) is a common feature in patients suffering from allergic and nonallergic rhinitis, it is widely neglected during history taking, underdiagnosed in the majority of patients with rhinitis and rhinosinusitis, not considered as an outcome parameter in clinical trials on novel treatments for rhinitis and rhinosinusitis, and no target for routine treatment. In contrast to the simple nature of diagnosing NHR by a history of nasal symptoms induced by nonspecific exogenous and/or endogenous triggers, quantification is hardly performed in routine clinic given the lack of a simple tool for its diagnosis. So far, limited efforts have been invested into gaining better insight in the underlying pathophysiology of NHR, helping us to explain why some patients with inflammation develop NHR and others not. Of note, environmental and microbial factors have been reported to influence NHR, contributing to the complex nature of understanding the development of NHR. As a consequence of the neglect of NHR as a key clinical feature of rhinitis and chronic rhinosinusitis (CRS), patients with NHR might be suboptimally controlled and/or dissatisfied with current treatment. We here aim to provide a comprehensive overview of current knowledge on the pathophysiology, and the available tools to diagnose and treat NHR.

Nasal symptoms, epithelial injury and neurogenic inflammation in elite swimmers.

BACKGROUND: A high burden of lower airway symptoms is found in elite swimmers. To what extent elite swimmers suffer from upper airway symptoms and how these associate with nasal inflammation is less clear. We here aimed to evaluate upper airway symptoms and nasal inflammation in elite athletes. METHODOLOGY: Elite swimmers, indoor athletes and age-matched controls were recruited. Upper airway symptoms were assessed by sino-nasal outcome test (SNOT)-22 questionnaire. Visual Analogue score (VAS) for nasal symptoms as well as neurogenic and inflammatory mediators in nasal fluid were assessed at baseline, immediately and 24-hours after sport-specific training. The effect of hypochlorite on nasal epithelial cells was evaluated in vitro. RESULTS: Baseline SNOT-22 and VAS for nasal itch and impaired smell were significantly higher in swimmers compared to controls. Nasal substance P and uric acid levels were increased in elite swimmers 24-hours after swimming compared to baseline. In elite swimmers, uric acid levels 24-hours post-exercise correlated with baseline SNOT-22. As increased symptoms and inflammation were found in swimmers but not in indoor athletes, we hypothesized that hypochlorite exposure might be the underlying mechanism. In vitro, the highest dose of hypochlorite decreased nasal epithelial cell integrity and induced release of uric acid. CONCLUSION: Upper airway symptoms are frequently reported in elite swimmers. Intensive swimming resulted in a delayed increase of epithelial injury and neurogenic inflammation.

mySinusitisCoach: patient empowerment in chronic rhinosinusitis using mobile technology.

Mobile health technology is emerging to take a prominent position in the management of chronic diseases. These technologies aim at enhancing patient empowerment via education and self-management. To date, of all the different apps available for patients with sinus disease, none were developed by medical experts dealing with chronic rhinosinusitis (CRS). The European Forum for Research and Education in Allergy and Airway diseases (EUFOREA) has undertaken a multi-stakeholder approach for designing, developing and implementing a tool to support CRS patients in monitoring their symptoms and to provide patients with a digital support platform containing reliable medical information about their disease and treatment options. mySinusitisCoach has been developed by medical experts dealing with CRS in close collaboration with patients, primary care physicians and community pharmacists, meeting the needs of both patients and health care providers. From a research perspective, the generation of real life data will help to validate clinical studies, patient stratification and improve understanding of the socio-economic impact of CRS, thereby paving the way for better treatment strategies.

Therapeutic effect of capsaicin nasal treatment in patients with mixed rhinitis unresponsive to intranasal steroids.

Literature is convincing regarding the efficacy of capsaicin nasal treatment in idiopathic rhinitis (IR). However, up to 50% of IR patients do not meet the strict inclusion criteria of the trials conducted so far. As a consequence, the efficacy of capsaicin is unknown in a significant number of IR patients that do not meet the strict inclusion/exclusion criteria (J Allergy Clin Immunol. 2014;133:1332, J Allergy Clin Immunol. 2017; [Epub ahead of print]). "Mixed rhinitis" (MR) patients have more than one major etiologic factor involved in the mucosal pathology. We have no idea about the efficacy of capsaicin nasal spray in these patients nor about the time interval to seek a second application. We report here that capsaicin nasal spray is effective in a broader group of IR than the purely selected ones described before, that subjective nasal hyper-reactivity is a good predictor of positive outcome, and that the time interval for seeking a second treatment is likely to be shorter in MR patients than in the strictly selected IR patients.

MP29-02 reduces nasal hyperreactivity and nasal mediators in patients with house dust mite-allergic rhinitis.

BACKGROUND: Nasal hyperreactivity (NHR) is an important clinical feature of allergic rhinitis (AR). The efficacy of MP29-02 (azelastine hydrochloride (AZE) and fluticasone propionate [FP]) nasal spray on local inflammatory mediators and NHR in AR is unknown. We tested if MP29-02 decreases inflammatory mediators and NHR in AR and if this effect is due to restoration of nasal epithelial barrier function. METHODS: A 4-week double-blinded placebo-controlled trial with MP29-02 treatment was conducted in 28 patients with house dust mite (HDM) AR. The presence of NHR was evaluated by measuring reduction in nasal flow upon cold dry air exposure. The effects of AZE ± FP on barrier integrity and airway inflammation were studied in a murine model of HDM-induced NHR and on reduced activation of murine sensory neurons and human mast cells. RESULTS: MP29-02 but not placebo reduced NHR (P < .0001 vs P = .21), levels of substance P (P = .026 vs P = .941), and ß-hexosaminidase (P = .036 vs P = .632) in human nasal secretions. In wild-type C57BL6 mice, the reduction in ß-hexosaminidase levels (P < .0001) by AZE + FP treatment upon HDM challenge was found in parallel with a decreased transmucosal passage (P = .0012) and completely reversed eosinophilic inflammation (P = .0013). In vitro, repeated applications of AZE + FP desensitized sensory neurons expressing the transient receptor potential channels TRPA1 and TRPV1. AZE + FP reduced MC degranulation to the same extent as AZE alone. CONCLUSION: MP29-02 treatment reduces inflammatory mediators and NHR in AR. The effects of AZE + FP on MC degranulation, nasal epithelial barrier integrity, and TRP channels provide novel insights into the pathophysiology of allergic rhinitis.

Non-allergic rhinitis: Position paper of the European Academy of Allergy and Clinical Immunology.

This EAACI position paper aims at providing a state-of-the-art overview on nonallergic rhinitis (NAR). A significant number of patients suffering from persistent rhinitis are defined as nonallergic noninfectious rhinitis (NANIR) patients, often denominated in short as having NAR. NAR is defined as a symptomatic inflammation of the nasal mucosa with the presence of a minimum of two nasal symptoms such as nasal obstruction, rhinorrhea, sneezing, and/or itchy nose, without clinical evidence of endonasal infection and without systemic signs of sensitization to inhalant allergens. Symptoms of NAR may have a wide range of severity and be either continuously present and/or induced by exposure to unspecific triggers, also called nasal hyperresponsiveness (NHR). NHR represents a clinical feature of both AR and NAR patients. NAR involves different subgroups: drug-induced rhinitis, (nonallergic) occupational rhinitis, hormonal rhinitis (including pregnancy rhinitis), gustatory rhinitis, senile rhinitis, and idiopathic rhinitis (IR). NAR should be distinguished from those rhinitis patients with an allergic reaction confined to the nasal mucosa, also called "entopy" or local allergic rhinitis (LAR). We here provide an overview of the current consensus on phenotypes of NAR, recommendations for diagnosis, a treatment algorithm, and defining the unmet needs in this neglected area of research.

Damage-associated molecular pattern and innate cytokine release in the airways of competitive swimmers.

BACKGROUND: Daily intensive exercise by elite athletes can result in exercise-induced asthma especially in elite swimmers and this may be linked to epithelial damage. OBJECTIVE: To study airway epithelial damage and release of damage-associated molecular patterns (DAMPs) after intensive exercise in elite athletes and controls. METHODS: We recruited competitive swimmers (n = 26), competitive indoor athletes (n = 13) and controls (n = 15) without any history of asthma. Lung function was measured before, immediately after and 24 h after a 90-min intensive exercise protocol. Sputum induction was performed at baseline and 24 h after exercise. Exercise-induced bronchoconstriction (EIB) was assessed by the eucapnic voluntary hyperventilation test. RESULTS: Baseline sputum uric acid, high mobility group box-1, CXCL8 mRNA, sputum neutrophils and serum Clara cell protein-16 (CC-16) were significantly higher in competitive swimmers compared with controls. Intensive swimming for 90 min resulted in an increase of sputum IL-1ß, IL-6 and TNF mRNA in competitive swimmers, and of sputum IL-6 mRNA and sputum neutrophils in controls. Although all participants were asymptomatic, seven competitive swimmers, one indoor athlete and one control met the criteria for EIB. CONCLUSION: Our findings show that the intensive training combined with exposure to by-products of chlorination induces airway epithelial damage in competitive swimmers. This is associated with increased damage-associated molecular patterns, innate cytokine release and neutrophilic airway inflammation.

Conjunctive therapy of cisplatin with the OCT2 inhibitor cimetidine: influence on antitumor efficacy and systemic clearance.

The organic cation transporter 2 (OCT2) regulates uptake of cisplatin in proximal tubules, and inhibition of OCT2 protects against severe cisplatin-induced nephrotoxicity. However, it remains uncertain whether potent OCT2 inhibitors, such as cimetidine, can influence the antitumor properties and/or disposition of cisplatin. Using an array of preclinical assays, we found that cimetidine had no effect on the uptake and cytotoxicity of cisplatin in ovarian cancer cells with high OCT2 mRNA levels (IGROV-1 cells). Moreover, the antitumor efficacy of cisplatin in mice bearing luciferase-tagged IGROV-1 xenografts was unaffected by cimetidine (P = 0.39). Data obtained in 18 patients receiving cisplatin (100 mg/m(2)) in a randomized crossover fashion with or without cimetidine (800 mg × 2) revealed that cimetidine did not alter exposure to unbound cisplatin, a marker of antitumor efficacy (4.37 vs. 4.38 µg·h/ml; P = 0.86). These results support the future clinical exploration of OCT2 inhibitors as specific modifiers of cisplatin-induced nephrotoxicity.
