BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory disease of the upper airway and is tightly linked with airway hyperresponsiveness (AHR) and asthma. However, the surrogate biomarkers for indicating AHR and asthma in patients with CRSwNP remain elusive. OBJECTIVE: To investigate the surrogate biomarkers for indicating AHR and asthma in patients with CRSwNP. METHODS: In this study, sinonasal tissues were collected from 42 patients with CRSwNP (asthma, n = 17; asymptomatic AHR, n = 11; non-AHR, n = 14), 11 patients with chronic rhinosinusitis without nasal polyps (CRSsNP), and 13 controls...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) has a high propensity for recurrence. Studies suggest that eosinophilia influences disease severity and surgical outcomes, but the selection of sinonasal site for measuring eosinophilia has not been examined. The aim of this study was to investigate how region-specific tissue eosinophilia affects radiographic severity, comorbidity prevalence, and polyp recurrence risk following sinus surgery. METHODS: Eosinophil cationic protein (ECP) levels in uncinate tissue (UT) and nasal polyp (NP) homogenates from 116 CRSwNP patients were measured using enzyme-linked immunosorbent assay (ELISA)...

Asthma is a common chronic disease with several variant phenotypes and endotypes. NSAID-exacerbated respiratory disease (NERD) is one such endotype characterized by asthma, chronic rhinosinusitis (CRS) with nasal polyps, and hypersensitivity to aspirin/cyclooxygenase-1 inhibitors. NERD is more associated with severe asthma than other asthma phenotypes. Regarding diagnosis, aspirin challenge tests via the oral or bronchial route are a standard diagnostic method; reliable in vitro diagnostic tests are not available...

In patients with COPD, there is controversy regarding the association of blood eosinophil (Eos) levels with 1) exacerbation frequency and 2) the effect of inhaled corticosteroids for prevention of exacerbations. To determine whether Eos define subgroups of patients exhibiting attributes of COPD clinical phenotypes, we compared clinical features and mortality rates in COPD patients from the Initiatives BPCO French cohort categorized using different thresholds of blood Eos levels. The following data were collected at inclusion: medical and smoking history, occupational exposures, dyspnea, cough and sputum production, exacerbations in the previous year, history of allergy and asthma, nasal symptoms, body mass index, St George Respiratory Questionnaire (SGRQ) total score, post-bronchodilator spirometry, comorbidities, and medications...

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: 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...

BACKGROUND: Distinguishing eosinophilic nasal polyps (NP) from noneosinophilic NP will impact prognosis and therapeutic responsiveness. OBJECTIVE: To investigate the ability of clinical history and biomarkers to distinguish these conditions. METHODS: A total of 74 consecutive patients undergoing surgery for NP were enrolled. Clinical presentations were evaluated using the 22-item sinonasal outcome test (SNOT-22). Biomarkers included absolute eosinophil count, IgE, and extent of tissue hyperplasia on sinus computed tomography scan...

We argue that asthma be considered a syndrome caused by multiple inflammatory pathogenic processes. Bronchial hyperresponsiveness, reversible airflow limitation, and chronic airway inflammation characterize asthma pathophysiology. Personalized Medicine, i.e. a tailored management approach, is appropriate for asthma management and is based on the identification of discrete phenotypes and endotypes. Biomarkers can help define phenotypes and endotypes. Several biomarkers have been described in asthma, but most of them are not commonly available or still need external validation...

RATIONALE: Periostin is a matricellular protein that is involved in the pathophysiology of allergic rhinitis, chronic rhinosinusitis, and asthma. Associations of serum periostin with systemic and airway eosinophilic inflammation and comorbid chronic rhinosinusitis in patients with asthma have been demonstrated. Although serum periostin is positioned as a marker of helper T cell 2 immune responses, its implication regarding the presence of comorbid upper airway diseases in patients with asthma remains unclear...

The last year has seen great progress in the understanding of upper airway disease and in its management. For allergic rhinitis, authors focused on the prediction of and effect on the natural course of disease. New evidence was published for the disease-modifying effect of allergen immunotherapy in terms of avoidance of new sensitizations and prevention of asthma in either randomized or real-life studies. Specifically, for patients with house dust mite allergies, which are often underestimated and difficult to diagnose, the efficacy of SQ house dust mite sublingual immunotherapy tablets has been demonstrated in patients with allergic rhinitis and asthma...

Periostin acts both as an extracellular matrix protein belonging to the fasciclin family and as a matricellular protein functioning in cell activation by binding to its receptors on the cell surface. It has been established that periostin is a downstream molecule of interleukin (IL)-13, a signature type 2 cytokine, and that periostin plays an important role in the pathogenesis of allergic diseases, including asthma. Based on these findings, much attention has been paid to periostin as a biomarker useful in the treatment of asthma...

Asthma and allergies are today the most common chronic diseases in children and the leading causes of school absences, chronic medication usage, emergency department visits and hospitalizations, which affect all members of the family and represent a significant societal and scientific challenge. These highly prevalent disorders are thought to originate from immune distortion in early childhood, but the etiology and heterogeneity of the disease mechanisms are not understood, which hampers preventive initiatives and makes treatment inadequate...

Chronic rhinosinusitis (CRS) is a persistent inflammatory disease that affects a multitude of people worldwide. The pathogenesis of CRS involves many factors including genetics, status of the sinonasal microbiome, infections, and environmental influences. Comorbidities associated with CRS include asthma, allergic rhinitis, bronchiectasis, and certain kinds of immunodeficiency. CRS can be divided into different subtypes based on endotypes and phenotypes. Infectious CRS is one such category. The etiology of infectious CRS is usually secondary to chronic bacterial infection that commonly begins with a viral upper respiratory tract infection...

Chronic rhinosinusitis with nasal polyps (CRSwNP) is an important clinical entity diagnosed by the presence of both subjective and objective evidence of chronic sinonasal inflammation. Symptoms include anterior or posterior rhinorrhea, nasal congestion, hyposmia, and/or facial pressure or pain that last for a duration of more than 12 weeks. Nasal polyps are inflammatory lesions that project into the nasal airway, are typically bilateral, and originate from the ethmoid sinus. Males are more likely to be affected than females, but no specific genetic or environmental factors have been strongly linked to the development of this disorder to date...

BACKGROUND: Eosinophils are thought to play a significant role in nasal polyposis, but the exact mechanism by which they contribute to polyposis remains unclear. Therefore, we proposed to test the hypothesis that peripheral blood eosinophilia (PBE) is a surrogate and biomarker for polyp load. To do this, we examined whether PBE levels correlate with nasal polyp load in a longitudinal manner. METHODS: We retrospectively analyzed the fluctuation of PBE and nasal polyp load in each patient (n = 61) assessed preoperatively, 1-2 months postoperatively, and 3-12 months postoperatively...

BACKGROUND: Broccoli sprouts (BS) are the richest source of sulforaphane (SFN), which is a potent inducer of phase II enzymes, which play a critical role in preventing oxidative stress (OS) and inflammation. OBJECTIVES: The objective of this study was to determine if ingestion of whole BS improves airway inflammatory and physiologic outcomes, and OS in adults with asthma and allergic sensitization to an indoor allergen. METHODS: The study is a double-blind, placebo-controlled, randomized trial to compare the effects of BS with placebo (alfalfa sprouts [AS]) on airway inflammation and markers of OS...

BACKGROUND: Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory condition of the sinonasal mucosa consisting of poorly defined subtypes and characterized by variable clinical manifestations, responses to therapy, and underlying pathophysiologies. In the related disorder of asthma, progress has been made in defining disease subtypes on both clinical and pathophysiologic levels, facilitating the development of targeted biologic pharmacotherapy. The potential role of these drugs for the management of CRS will be reviewed...

BACKGROUND: Current phenotyping of chronic rhinosinusitis (CRS) into chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP) might not adequately reflect the pathophysiologic diversity within patients with CRS. OBJECTIVE: We sought to identify inflammatory endotypes of CRS. Therefore we aimed to cluster patients with CRS based solely on immune markers in a phenotype-free approach. Secondarily, we aimed to match clusters to phenotypes...

Periostin, a 90-kDa extracellular matrix protein, has been attracting attention as a novel biomarker of airway inflammatory diseases such as allergic rhinitis (AR) and asthma. Although oral administration of quercetin to patients with AR can favorably modify the clinical condition of this disease, the influence of quercetin on periostin functions is not well understood. The present study was, therefore, undertaken to examine the influence of quercetin on the production of both periostin and periostin-induced eosinophil chemoattractants from human nasal epithelial cells (HNEpC) in vitro...
