BACKGROUND: Chronic airway inflammatory diseases such as chronic rhinosinusitis with nasal polyps and asthma showed increased nasal Staphylococcus aureus (S. aureus) colonization. Serine protease like protein D (SplD) and other closely related proteases secreted by S. aureus have recently been identified as inducers of allergic asthma in humans and mice but their mechanism of action is largely unknown. OBJECTIVE: We investigated the role of recombinant SplD in driving Th2-biased responses and IgE formation in a murine model of allergic asthma...

In western countries, 85% of chronic rhinosinusitis with nasal polyp disease reveals a type 2 inflammatory pattern with expression of IL-4, -5, and -13 as well as increased concentrations of IgE, whereas chronic rhinosinusitis without nasal polyps merely expresses these biomarkers. The degree of type 2 inflammation furthermore is associated with disease severity, asthma comorbidity, and recurrence of disease after surgery. Therefore, these biomarkers also form the targets for innovative therapeutic approaches such as monoclonal antibodies directed against IgE, IL-5, and IL-4 receptor alpha, blocking the activity of IL-4 and -13...

BACKGROUND: Chronic rhinosinusitis (CRS) is commonly classified into CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Structured histopathologic reporting has the potential to identify salient histologic markers to differentiate subtypes and provide insights into pathophysiologic mechanisms in CRS. METHODS: A structured histopathology report of 13 variables was prospectively employed to analyze ethmoid sinus tissue removed during endoscopic sinus surgery for 99 patients, including 43 CRSsNP and 56 CRSwNP...

BACKGROUND: Despite the close linkage between rhinitis, chronic rhinosinusitis (CRS) and asthma, relevant biomarkers of both upper and lower airway inflammation are rare. METHODS: Patients with asthma (without upper airway disease [UAD; n = 24], with rhinitis [n = 25], CRS [n = 24], and nasal polyps [n = 2]), isolated rhinitis (n = 13), isolated CRS (n = 13), and 10 healthy controls were prospectively recruited. Fractional exhaled nitric oxide (NO) levels at 50 mL/s (FeNO50), nasal NO levels, Lund-Macay-scores of sinus computed-tomography and an asthma control questionnaire (ACQ) were evaluated...

Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disease with various underlying pathophysiologic mechanisms which translate to endotypes, in contrast to clinical phenotypes or histological subtypes. Defining endotypes can help clinicians predict disease prognosis, select subjects suitable for a specific therapy, and assess risks for comorbid conditions, including asthma. Therefore, with recent advancement of biologicals in CRS clinical trials, endotyping can be a breakthrough in treating recalcitrant CRS...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is often comorbid with asthma and resistant to therapeutic interventions. We recently reported that excessive fibrin deposition caused by impairment of fibrinolysis might play pivotal role in forming nasal polyp. Nattokinase (NK), a serine protease produced by Bacillus subtilis, has been reported to be a strong fibrinolytic enzyme. NK could be a promising drug candidate for use in the treatment of both CRSwNP and asthma. The objective of this study was to investigate the effects of NK on nasal polyp tissues from patients with CRSwNP...

Cough is the most common symptom for which patients seek medical attention. Chronic cough is defined when the symptom lasts for more than 8 weeks. It significantly alters quality of life. Chronic cough may be the dominant symptom which reveals a large number of diseases, not only respiratory. It is classic to distinguish chronic cough according to the chest X Ray results. In case of normal chest X ray, which is the most frequent condition, the diagnosis of tobacco-associated chronic bronchitis, drug induced cough, asthma, oesophageal reflux and rhinosinusitis should be considered...

A number of chronic inflammatory diseases are associated with IgE-mediated immunologic hypersensitivity, including atopic dermatitis, chronic rhinosinusitis, and asthma. Pathogenetic studies of well-characterized patient groups has allowed investigators to more precisely define the molecular pathways involved in these diseases. Specific cytokines and chemokines, as well as other unique proteins, have now been identified in each of these common disorders and a number of medications are currently in development for inhibiting their actions...

Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma...

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) comprises the triad of chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and intolerance to inhibitors of the cyclooxygenase-1 (COX-1) enzyme. The prevalence of AERD remains unclear, and few studies have compared the clinical characteristics of patients with AERD to those with CRSwNP alone, asthma alone, or both CRSwNP and asthma. OBJECTIVE: To determine the prevalence of AERD within a tertiary care setting, and to identify unique clinical features that could distinguish these patients from those with both CRSwNP and asthma or with CRSwNP alone...
