RATIONALE: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have been shown to be vitamin D3 (VD3) deficient, which is associated with more severe disease and increased polyp size. To gain mechanistic insights into these observational studies, we examined the impact of VD3 deficiency on inflammation and VD3 metabolism in an Aspergillus fumigatus (Af) mouse model of chronic rhinosinusitis (Af-CRS). METHODS: Balb/c mice were fed control or VD3 deficient diet for 4 weeks...

Patients undergoing revision functional endoscopic sinus surgery (rFESS) for refractory chronic rhinosinusitis (CRS) are more likely to be older, have worse pre-operative Lund-Mackay CT scores, and poorer quality-of-life scores than primary FESS patients. Patients with more aggressive forms of CRS such as CRS with nasal polyposis (CRSwNP) or allergic fungal rhinosinusitis (AFRS) may fare worse in the long term with residual disease and be more likely to seek out tertiary institutions for treatment including rFESS...

OBJECTIVE: Laryngopharyngeal reflux disease (LPRD) is one of potential factors in recalcitrant chronic rhinosinusitis with or without polyps. An increase in junctional permeability in the nasal mucosa in LPRD may be due to disrupted protein bridge formation with cell-to-cell adhesion molecules such as E-cadherin. Despite the relationship between nasal mucosal inflammation and LPRD, the clear mechanism by which acid reflux affects the nasal epithelium remains unclear. METHODS: The expression levels and distribution patterns of E-cadherin in primary culture of nasal epithelial cells after acid exposure with or without dexamethasone and matrix metalloproteinase (MMP) inhibitor were determined using Western blot and immunocytochemistry...

Clinical practice guideline development should be driven by rigorous methodology, but what is less clear is where quality improvement enters the process: should it be a priority-guiding force, or should it enter only after recommendations are formulated? We argue for a stakeholder-driven approach to guideline development, with an overriding goal of quality improvement based on stakeholder perceptions of needs, uncertainties, and knowledge gaps. In contrast, the widely used topic-driven approach, which often makes recommendations based only on randomized controlled trials, is driven by epidemiologic purity and evidence rigor, with quality improvement a downstream consideration...

INTRODUCTION: Aspirin-exacerbated respiratory disease (AERD) is a clinical entity characterized by hypersensitivity to aspirin leading to asthma and chronic rhinosinusitis with nasosinusal polyposis. The pathophysiology of the disease involves disruption at the level of arachidonic acid metabolism. Therefore, genetic association studies have been focused on the genes coding this pathway. As other mechanisms involved in the genesis of the disease were elucidated, the corresponding genes were also explored...

Asthma is characterized by episodic, reversible airflow obstruction associated with variable levels of inflammation. Over the past several decades, there has been an increasing appreciation that the clinical presentation of asthma comprises a diverse set of underlying pathologies. Rather than being viewed as a single disease entity, asthma is now thought of as a clinical syndrome with the involvement of multiple pathological mechanisms. While it is appreciated that eosinophilia is present in only a subset of patients, it remains a key feature of asthma and other eosinophilic disorders such as atopic dermatitis, eosinophilic esophagitis, and chronic rhinosinusitis with nasal polyps...

Leukotriene signaling is essential in many diseases, including asthma, allergic rhinitis, atherosclerosis and inflammatory bowel disease. Nevertheless, the expression of cysteinyl leukotrienes (CysLTs) and its receptors (CYSLTRs) in different types of nasal polyps (NPs), and the role of their antagonist in the treatment of refractory chronic rhinosinusitis with nasal polyps (CRSwNP) are not well understood. The following study investigates the expression of CysLTs and CYSLTRs in different types of NPs, as well as the role of leukotriene receptor antagonist (montelukast) in refractory NPs...

BACKGROUND: Previous studies have identified subdomains of the 22-item Sino-Nasal Outcome Test (SNOT-22), reflecting distinct and largely independent categories of chronic rhinosinusitis (CRS) symptoms. However, no study has validated the subdomain structure of the SNOT-22. This study aims to validate the existence of underlying symptom subdomains of the SNOT-22 using confirmatory factor analysis (CFA) and to develop a subdomain model that practitioners and researchers can use to describe CRS symptomatology...

Chronic rhinosinusitis (CRS) affects 5-15% of the global population. In some patients, the infectious exacerbations of the disease are recalcitrant to medical treatment and surgery. These cases are probably associated with the presence of bacterial biofilms. Bacteriophage (phage) therapy seems to be a promising antibiofilm strategy. The efficacy of phage therapy in sinonasal infections has been demonstrated both in vitro and in animal models. In the past, phage preparations were also administered to humans with CRS with favorable outcomes and no significant side effects...

BACKGROUND: Carrageenans have shown to reduce the viral load in nasal secretions and lower the incidence of secondary infections in children with common cold. Despite the widespread use of carrageenans in topical applications, the effect of carrageenans on the sinonasal epithelial barrier has not been elucidated. We investigate the effect of different carrageenans on the sinonasal epithelial barrier and inflammatory response in vitro. METHODS: Iota and Kappa carrageenan delivered in saline irrigation solutions applied to air-liquid interface (ALI) cultures of primary human nasal epithelial cells from chronic rhinosinusitis patients and controls...

Introduction:Pseudomonas aeruginosa infections are prevalent amongst chronic rhinosinusitis (CRS) sufferers. Many P. aeruginosa strains form biofilms, leading to treatment failure. Lytic bacteriophages (phages) are viruses that infect, replicate within, and lyse bacteria, causing bacterial death. Aim: To assess the activity of a phage cocktail in eradicating biofilms of ex vivo P.aeruginosa isolates from CRS patients. Methods: P. aeruginosa isolates from CRS patients with and without cystic fibrosis (CF) across three continents were multi-locus sequence typed and tested for antibiotic resistance...

This review article highlights the importance and advantages of the drug delivery systems applied via the nasal route after endoscopic sinus surgery (ESS) for patients suffering from chronic rhinosinusitis. After ESS, patients often require ongoing topical and systemic medication. To reduce the incidence of immediate and delayed post-surgical complications, a variety of temporary postoperative nasal interventions are currently used. However, newly developed intranasal drug delivery devices can enhance tissue recovery after endoscopic sinus surgery by releasing therapeutic drugs locally, while providing structural support to reduce tissue adhesion and scaring...

OBJECTIVE: Staphylococcus aureus (S. aureus) infection is known to contribute to the severity and recalcitrance of chronic rhinosinusitis (CRS), and its secreted products have been shown to alter the airway barrier. Extracellular proteases secreted by S. aureus are thought to be important in epithelial infection and immune evasion; however, their effect on airway mucosal barrier function is not known. METHODS: To investigate the impact of extracellular proteases on airway epithelial integrity, the purified S...
