OBJECTIVES/HYPOTHESIS: Olfactory dysfunction is common among the general population, with chronic rhinosinusitis (CRS) as one of the leading causes. Patients affected by CRS often report changes in taste sensations; however, quantitative measurements have not been performed to date. Therefore, the present study aimed to investigate gustatory and olfactory function in CRS patients prior to and after multimodal treatment. STUDY DESIGN: Prospective cohort study. METHODS: Twenty-one patients suffering from CRS with nasal polyps (14 male, seven female) with a mean age of 48 ± 15 years were included in the study...

OBJECTIVE: To review the current understanding of the role of infection and antibiotics in chronic rhinosinusitis. REVIEW METHODS: PubMed literature search. RESULTS: Chronic rhinosinusitis (CRS) in adults is an inflammatory condition and the role of infection is unclear. Biofilms are present in both CRS and normal patients so their role in CRS is unknown. Sinus cultures in CRS demonstrate a mixture of aerobic and anaerobic bacteria but may be hard to interpret due to contaminating nasal flora...

OBJECTIVE: Chronic rhinosinusitis (CRS) is a multifactorial inflammatory disease. In particular, CRS with eosinophilic features and/or nasal polyps (NPs) is often recalcitrant to current treatment; thus, appropriate animal models are mandatory to elucidate the pathogenesis of CRS and develop novel and efficient treatment modalities. The author reviewed the recently proposed animal models in CRS and discussed the pathophysiologic insights gained. Data Sources: Articles in the English language referenced in MEDLINE/PubMed from the year 2006 onward (for last 10 years)...

BACKGROUND: Patients with aspirin-exacerbated respiratory disease (AERD) are distinguished from patients with aspirin-tolerant asthma (ATA) by significantly higher baseline concentrations of urinary leukotriene E4 (uLTE4). However, an overlap between the individual values of the groups exists. OBJECTIVE: The objective of this study was to estimate the discriminative value of uLTE4 concentration in differentiating between patients with AERD and patients with ATA and evaluate the diagnostic accuracy of uLTE4 measurement alone and added to clinical parameters to predict AERD diagnosis in patients with asthma...

We found for the first time that IL-4 and IL-13, signature type 2 cytokines, are able to induce periostin expression. We and others have subsequently shown that periostin is highly expressed in chronic inflammatory diseases-asthma, atopic dermatitis, eosinophilc chronic sinusitis/chronic rhinosinusitis with nasal polyp, and allergic conjunctivitis-and that periostin plays important roles in the pathogenesis of these diseases. The epithelial/mesenchymal interaction via periostin is important for the onset of allergic inflammation, in which periostin derived from fibroblasts acts on epithelial cells or fibroblasts, activating their NF-κB...

Disruption of nasal epithelial tight junctions (TJs) and ciliary dysfunction are found in patients with chronic rhinosinusitis (CRS) and nasal polyps (NPs), along with an increase of p63-positive basal cells and histone deacetylase (HDAC) activity. To investigate these mechanisms, primary cultures of HNECs transfected with human telomerase reverse transcriptase (hTERT-HNECs) were transfected with siRNAs of TAp63 and ΔNp63, treated with the NF-kB inhibitor curucumin and inhibitors of HDACs, and infected with respiratory syncytial virus (RSV)...

BACKGROUND: The objective of this work was to evaluate the impact of asthma on the cost-effectiveness profile of endoscopic sinus surgery (ESS) compared to medical therapy for patients with chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: The study design consisted of a cohort-style Markov decision-tree cost utility analysis with a 35-year time horizon. Matched cohorts of CRSwNP patients with (n = 95) and without (n = 95) asthma who underwent ESS were compared with cohorts of patients from the national Medical Expenditures Survey Panel (MEPS) database who underwent medical management for chronic rhinosinusitis (CRS)...

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)...

Patients with chronic rhinosinusitis (CRS) often suffer from loss of olfactory function. Rhinosinusitis can be treated either by medical therapy or surgically (FESS). Postoperative outcome in terms of improving sense of smell has been controversial so far. The aim of our study was to determine the patients who would have better postoperative outcomes in terms of improving olfactory function. We collected data of patients undergoing FESS for chronic rhinosinusitis (either with or without nasal polyps) at our department during the years 2012-2015...

P63 is a regulator of cell-cell junction complexes in the epidermis. Claudin-4 is regulated via various factors in normal epithelial cells and diseases. We found that claudin-4 was directly regulated via p63 (TAp63 and ΔNp63) in human keratinocytes and nasal epithelial cells. In the epidermis of atopic dermatitis (AD), which contains ΔNp63-deficient keratinocytes, high expression of claudin-4 was observed. In primary keratinocytes, downregulation of ΔNp63 by treatment with short interfering RNA (siRNA)-p63 induced claudin-4 expression...

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...

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a highly heterogeneous disease with different host defence responses. However, whether periostin and vascular endothelial growth factor (VEGF) are similarly impaired in patients with eosinophilic CRSwNP (ENP) and those with non-eosinophilic CRSwNP (nENP) remains unclear. We sought to evaluate the expression and possible modulation of periostin and VEGF, regulated on activation normal T expressed and secreted (RANTES) and eotaxin-2 in the polyp tissues from 30 patients with ENP and from 36 patients with nENP and in middle turbinate tissues from 12 control subjects...

BACKGROUND: Although nasal polyps are one of the most frequent diseases, their etiopathogenesis remains unclear.Since eosinophils are the main inflammatory cells in the substantial proportion of nasal polyp tissues, they are considered potentially responsible for the etiopathogenesis and prognosis of the disease. Aim of this study was to investigate the relation between mucosal and peripheral eosinophilia and their relation with disease severity in nasal polyps. METHODS: The study included 53 patients with nasal polyps who underwent endoscopic sinus surgery...

One subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by the development of a T-helper type 2 (Th2) response and eosinophilic infiltration. Here, we aimed to establish an eosinophilic CRSwNP murine model, which would be essential to understand the underlying pathogenesis and establish a treatment strategy. C57BL/6 mice were challenged intranasally with a mixture of an Aspergillus oryzae-derived protease (AP) and ovalbumin (OVA) for 6, 8, or 12 consecutive weeks (12 mice/group); control mice received the same volume of phosphate-buffered saline for 12 weeks (n = 12)...
