Abstract
OBJECTIVES The purpose of this study is to investigate the lung function in Chronic Rhinosinusitis (CRS) patients with Chronic Cough (CC). METHODS A total of 1413 CC patients were retrospectively screened and 109 CRS patients with CC were enrolled. Lung function, Lund-Mackay Computed Tomography (CT) score, smoking status, peripheral blood eosinophil count, and immunoglobulin E concentration in serum samples, and Sino-Nasal Outcome Test were examined. Normal control subjects are also recruited. RESULTS The Forced Expiratory Volume in 1 second (FEV1.0), Percent Predicted FEV1.0, and FEV1.0/Forced Vital Capacity (FVC) ratio in the patients were significantly low as compared with the control subjects. The FEV1.0/FVC ratio was negatively correlated with the Lund-Mackay CT scores of the patients with a high CT score. CONCLUSIONS The CRS patients with CC should be investigated with lung function. In addition, the multidisciplinary evaluation including a pulmonologist is needed to manage the CRS patients with CC. LEVEL OF EVIDENCE Level 4.

Abstract
BACKGROUND Exposure to airborne urban particulate matter (UPM) has been closely related to the development and aggravation of respiratory disease, including sinonasal disorders. OBJECTIVE The aims of this study were to investigate the effect of UPM on nasal epithelial tight junctions (TJs) and mucosal barrier function and delineate the underlying mechanism by using both in vitro and in vivo models. METHODS In this study, human nasal epithelial cells (hNECs) and BALB/c mice were exposed to UPMs. UPM 1648a and 1649 b were employed. TJ and endoplasmic reticulum (ER) stress marker expression was measured using western blot analysis and immunofluorescence. TJ integrity and nasal epithelial barrier function were evaluated by transepithelial electric resistance (TER) and paracellular flux. In addition, the effects of N-acetyl-L-cysteine (NAC) on UPM-induced nasal epithelial cells were investigated. RESULTS UPM significantly impaired the nasal epithelial barrier, as demonstrated by decreased protein expression of TJ and ER stress markers in human nasal epithelial cells. This finding was in parallel to reduced transepithelial electrical resistance and increased fluorescein isothiocyanate-dextran permeability. Pretreatment with NAC decreased the degree of UPM-mediated ER stress and restored nasal epithelial barrier disruption in human nasal epithelial cells (hNEC) and the nasal mucosa of experimental animals. CONCLUSION These data suggest that UPMs may induce nasal epithelial barrier dysfunction by targeting TJs and ER stress could be related in this process. Based on these results, we suggest that suppression of this process with an inhibitor targeting ER stress responses could represent a novel promising therapeutic target in UPM-induced sinonasal disease.

Abstract
INTRODUCTION Unified airway disease where upper respiratory tract inflammation including chronic rhinosinusitis (CRS) affects lower airway disease is known from asthma, bronchiectasis, cystic fibrosis and primary ciliary dyskinesia but little is known about CRS and health related quality of life in COPD. We investigate firstly, the prevalence of CRS in COPD. Secondly the impact of CRS on HRQoL. Thirdly, risk factors for CRS in COPD. METHODS cross-sectional study of CRS in 222 COPD patients from 2017 to 2019 according to EPOS2012/2020 and GOLD2019 criteria. Patients completed the COPD assessment test (CAT), Medical Research Council dyspnea scale and Sinonasal outcome test 22 (SNOT22) and questions on CRS symptoms. They then had a physical examination including flexible nasal endoscopy, CT-sinus scan and HRCT-thorax. RESULTS 22.5% of COPD patients had CRS and 82% of these were undiagnosed prior to the study. HRQoL (CAT, SNOT22 and the SNOT22-nasal symptom subscore) was significantly worse in COPD patients with CRS compared with those without CRS and healthy controls. Multiple logistic regression analysis suggests that the most likely candidate for having CRS was a male COPD patient who actively smoked, took inhaled steroids, had a high CAT and SNOT22_nasal symptom subscore. DISCUSSION the largest clinical study of CRS in COPD and the only study diagnosing CRS according to EPOS and GOLD. This study supports unified airway disease in COPD. The SNOT22_nasal symptoms subscore is recommended as a standard questionnaire for COPD patients and patients at risk should be referred to an otorhinolaryngologist.

Abstract
The validity of the united airway disease concept for rhinosinusitis (RS) and chronic obstructive pulmonary disease (COPD) has been questioned because of methodological limitations in previous studies. In this study we investigated the prevalence of RS without nasal polyps (RSsNP) and the severity of sinonasal symptoms in COPD and a corresponding control group. We also evaluated the diagnostic accuracy of these symptoms for RSsNP in COPD. 90 COPD patients and 93 controls were included in an observational cross-sectional study where globally accepted diagnostic criteria of RS and COPD (EPOS 2012 and GOLD) were incorporated; symptomatic and endoscopic criteria for the diagnosis of RS, and spirometry with reversibility for diagnosis of COPD. RS symptoms were identified by responses to the sinonasal outcome test (SNOT-22), nasal endoscopy identified signs of sinonasal disease and discriminated between RS with and without nasal polyps, and visual analogue scales (VAS) rated the severity of sinonasal symptoms. We found RSsNP in 51% of our COPD patients which is threefold greater than in the control group (p<0.001). Nasal discharge (72%) and nasal obstruction (62%) were the two most frequently reported symptoms in COPD. The diagnostic accuracy for RSsNP is better for the composite VAS for rhinological symptoms than for facial symptoms. We conclude that RSsNP is present in 51% of our COPD patients, which is significantly more prevalent compared to a corresponding control group. These results suggest that COPD is associated with RS.

Abstract
PURPOSE Chronic cough is a common complaint. Because the pathophysiology of chronic cough is complicated, the management of chronic cough is challenging. To the best of our knowledge, no previous study has examined the effect of macrolide antibiotics in chronic cough patients with chronic rhinosinusitis. The purpose of this study is to determine the changes in lung function for chronic cough patients with chronic rhinosinusitis who are treated by clarithromycin and carbocisteine. MATERIALS AND METHODS Thirty-two chronic cough patients with chronic rhinosinusitis were recruited. Patients using inhaled corticosteroids and/or a bronchodilator, asthmatic patients, and patients with abnormal findings on auscultation and/or chest X-ray examination were excluded from this study. The patients received low-dose clarithromycin treatment for 3 months. Both before and after the treatment, a computed tomography (CT) scan of the paranasal sinuses, lung function test, peripheral blood test, and sino-nasal outcome test (SNOT-20) were applied. RESULTS Both the lung function and Lund-MacKay CT scores were improved by the long-duration therapy with macrolide antibiotics. The change in obstructive pulmonary function and the improvement of the CT score in each subject were significantly correlated. SNOT scores also improved after the treatment. CONCLUSIONS The macrolide antibiotics treatment has beneficial effects on lung function in non-asthmatic chronic cough patients with normal chest X-ray findings. The improvement of chronic rhinosinusitis may have some role in the lung condition. Upper respiratory tract examination and treatment may be useful for the management of chronic cough.

Abstract
INTRODUCTION Burnt sugarcane harvesting requires intense physical exertion in an environment of high temperature and exposure to particulate matter. OBJECTIVE To evaluate the effects of burnt sugarcane harvesting on rhinitis symptoms and inflammatory markers in sugarcane workers. METHODS A total of 32 male sugarcane workers were evaluated with questionnaire for rhinitis symptoms, and for inflammatory markers on peripheral blood and nasal lavage, in the non-harvesting, and 3 and 6 months into the sugarcane harvesting period. Weather data and particulate matter fine concentrations were measured in the same day. RESULTS The particulate matter concentrations in sugarcane harvesting were 27 (23-33μg/m3), 112 (96-122μg/m3), and 63 (17-263μg/m3); 24h temperatures were 32.6 (25.4-37.4°C), 32.3 (26.7-36.7°C) and 29.7 (24.1-34.0°C) and relative humidities were 45.4 (35.0-59.7%), 47.9 (39.1-63.0%), and 59.9 (34.7-63.2%) in the non-harvesting period, three and 6 months of the harvesting period. The age was 37.4±10.9 years. The prevalence of rhinitis symptoms was significantly higher at 3 months of the harvesting period (53.4%), compared to non-harvesting period (26.7%; p=0.039) and at 6 months into the harvesting period (20%; p=0.006). Concentrations of interleukin 6 (IL-6) in nasal lavage increased after 3 months of the harvesting period compared to the non-harvesting period (p=0.012). The presence of rhinitis symptoms, after 3 months of the harvesting period, was directly associated with blood eosinophils and inversely associated with neutrophils. CONCLUSIONS After 3 months of work in burnt sugarcane harvesting the prevalence of rhinitis symptoms and IL-6 in nasal lavage increased. Furthermore, eosinophil counts were directly associated with the rhinitis symptoms in the period of higher concentration of particulate matter.

Abstract
Purpose Epidemiologic studies have reported that Asian sand dust (ASD) is associated with chronic inflammatory diseases of the respiratory system. Glucocorticoids (GCs) have potent anti-inflammatory properties. The aims of this study were to evaluate the effects of GCs on ASD-induced interleukin-32 (IL-32) expression and to identify the underlying signaling pathways in airway epithelial cells. Methods A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used to evaluate cytotoxicity in A549 and human primary nasal epithelial cells. Expression levels of IL-32 messenger RNA and protein were measured by Western blot, real-time polymerase chain reaction, ELISA, and immunofluorescence staining. Signaling pathways were analyzed using specific inhibitors of Akt, MAPK, or NF- κB. The effects of GCs on the expression of ASD-induced IL-32 were confirmed with ex vivo organ cultures of the nasal interior turbinate. Results ASD (0–400 ng/mL) had no significant cytotoxic effects in A549 cells and human primary nasal epithelial cells. Expression levels of IL-32 were dose-dependently upregulated by ASD treatment in A549 cells. ASD induced phosphorylation of Akt, MAPK, and NF-κB, whereas GCs and specific inhibitors of Akt, MAPK, and NF-κB downregulated these activations and the expression of IL-32. These findings were further confirmed in human primary nasal epithelial cells and ex vivo organ cultures of the nasal interior turbinate. Conclusions GCs have an inhibitory effect on ASD-induced IL-32 expression via the Akt, MAPK, and NF- κB signaling pathways in airway epithelial cells.

Abstract
BACKGROUND A remarkable relationship between upper airway conditions and lung diseases has been reported. At the same time, sinonasal findings in chronic cough patients have not been fully examined. OBJECTIVE The purpose of this study is to show paranasal sinus findings and lung function in chronic cough patients without asthma and chest X-ray abnormalities. METHODS A total of 1412 patients with persistent cough were enrolled in this study. Of these patients, 376 patients were evaluated for further examination, as the patients with asthma and/or chest X-ray abnormality were excluded from the study. Normal control subjects without any chronic respiratory symptoms were also recruited. Pulmonary function was examined by spirometry. A bronchial obstruction reversibility test was applied. The Lund-Mackay computed tomography (CT) score, peripheral blood eosinophil count, and immunoglobulin E concentration in serum samples were examined. The Sino-Nasal Outcome Test was used to determine the severity of clinical symptoms. RESULTS The patients with an abnormal soft tissue shadow in the paranasal sinus had significant obstructive lung function. The percent predicted forced expiratory volume in 1 second (FEV1.0) and the FEV1.0/forced vital capacity ratio negatively correlated with Lund-Mackay CT scores both before and after bronchodilator inhalation. There was a statistically significant correlation between pulmonary function and eosinophil count. CONCLUSION The patients with chronic cough frequently had paranasal sinus abnormalities. The Lund-Mackay CT score may be useful for assessing the condition of the lower airway in chronic cough patients. Upper airway examinations should play a part in the management of chronic cough.

Abstract
The human respiratory tract is exposed daily to airborne fungi, fungal enzymes, and secondary metabolites. The endemic fungi Histoplasma capsulatum, Coccidioides spp, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, and occasionally Aspergillus fumigatus, are primary pulmonary pathogens of otherwise healthy people. Such infections resolve in most people, and only a few infections lead to disease. However, many fungi are directly allergenic by colonising the respiratory tract or indirectly through contact with cell wall constituents and proteases, causing or exacerbating allergic disease. Increasing evidence implicates high indoor fungal exposures as a precipitant of asthma in children and in worsening asthma symptoms. Lung or airways infection by endemic fungi or aspergillus can be diagnosed with respiratory sample culture or serum IgG testing. Sputum, induced sputum, or bronchial specimens are all suitable specimens for detecting fungi; microscopy, fungal culture, galactomannan antigen, and aspergillus PCR are useful tests. Antifungal treatment is indicated in almost all patients with chronic cavitary pulmonary infections, chronic invasive and granulomatous rhinosinusitis, and aspergillus bronchitis. Most patients with fungal asthma benefit from antifungal therapy. Adverse reactions to oral azoles, drug interactions, and azole resistance in Aspergillus spp limit therapy. Environmental exposures, genetic factors, and structural pulmonary risk factors probably underlie disease but are poorly understood.

Abstract
PURPOSE OF REVIEW The present review summarizes the recent literature on the relation between chronic workplace irritant exposures and asthma, focusing on exposures of low to moderate levels. We discuss results from epidemiological surveys, potential biological mechanisms, and needs for further research. These aspects are largely illustrated by studies on exposure to cleaning products. RECENT FINDINGS Recent results from nine population-based and workplace-based epidemiological studies, mostly cross-sectional, found an increased risk of both new-onset and work-exacerbated asthma among participants exposed to moderate level of irritants and/or cleaning products. SUMMARY Evidence of a causal effect of chronic workplace irritant exposure in new-onset asthma remains limited, mainly because of a lack of longitudinal studies and the difficulty to evaluate irritant exposures. However, recent epidemiological studies strengthen the evidence of an effect of chronic exposure to irritants in work-related asthma. The underlying mechanism remains unknown but may be related to oxidative stress, neurogenic inflammation and dual irritant and adjuvant effects. However, disentangling chronic irritant effects from either acute irritant-induced asthma or immunological low molecular weight agent-induced asthma is difficult for some agents. Further research is needed to improve assessment of irritant exposures and identify biomarkers.

Abstract
Background Diesel exhaust particles (DEP) are a major source of air pollution. Nasal fibroblasts are known to produce various cytokines and chemokines. The aim of this study was to evaluate DEP-induced cytokines and chemokines in nasal fibroblasts and to identify the signaling pathway involved. Methods A cytokine and chemokine array performed after stimulation of nasal fibroblasts with DEP revealed that levels of IL-6 and IL-8 were increased most significantly among various cytokines and chemokines. RT—PCR and ELISA were used to determine the mRNA and protein expression levels of IL-6 and IL-8. Signaling pathways of p-38, Akt, and NF-κB were analyzed by western blotting, luciferase assay, and ELISA. Organ cultures of nasal interior turbinate were also developed to demonstrate the ex vivo effect of DEP on the expression of IL-6 and IL-8 and the associated signaling pathway. Results DEP increased the expressions of IL-6 and IL-8 in nasal fibroblasts at mRNA and protein levels. DEP induced phosphorylation of p38, Akt, and NF-κB, whereas inhibitors of p38, Akt, and NF-κB blocked these phophorylations and the expressions of IL-6 and IL-8. These findings were also observed in ex vivo organ culture of nasal inferior turbinate. Conclusions DEP induces expression of IL-6 and IL-8 via p38, Akt, and NF-κB signaling pathways in nasal fibroblasts. This finding suggests that air pollution might induce or aggravate allergic rhinitis or chronic rhinosinusitis.

Abstract
Objective measures can be used to assist the clinician to diagnose and treat nasal obstruction and also to quantify nasal obstruction in research. Objective measurements of nasal obstruction are as important as objective measurements of lung function. peak nasal inspiratory flow (PNIF), acoustic rhinometry (AR) and rhinomanometry (RM), with their specific peculiarity, assess different aspects of nasal obstruction. From the studies available in the literature, it seems that these methods roughly correlate with each other and that all of them can be alternatively utilized very well in research as well as in clinical practice. This review describes the various methods that can be used to measure nasal patency, airflow and resistance, mainly peak nasal inspiratory flow, rhinomanometry and acoustic rhinometry. PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population. PNIF normative data are available for children, adults and elderly subjects, and the availability of unilateral PNIF normal values allows evaluation of nasal sides separately. Just as in the lower airways, objective and subjective evaluation gives different information that together optimizes the diagnosis and the treatment of our patients. We argue that PNIF should be used regularly in every outpatient clinic that treats patients with nasal obstruction.
