Abstract
INTRODUCTION The Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy report provides guidance on effective management of chronic obstructive pulmonary disease (COPD) according to local healthcare systems. However, COPD is a heterogenous disease and certain aspects, including prevalence, disease-time course and phenotype distribution, can differ between countries. Moreover, features of clinical practice and healthcare systems for COPD patients can vary widely, even in geographically close and economically similar countries. AREAS COVERED Based on an initial workshop of respiratory physicians from eleven countries across Central and Eastern Europe (CEE) in December 2018 and subsequent discussions, this article offers region-specific insights from clinical practice and healthcare systems in CEE. Taking GOLD 2020 recommendations into account, we suggest approaches to adapt these into national clinical guidelines for COPD management in CEE. EXPERT OPINION Several factors should be considered when optimizing management of COPD in CEE compared with other regions, including differences in smoking status, vaccination uptake, prevalence of tuberculosis and nontuberculous mycobacteria, and variations in healthcare systems. We provide guidance and algorithms for pharmacologic and non-pharmacologic management of COPD for the following scenarios: initial and follow-up treatment, treatment of patients with frequent exacerbations, and withdrawal of inhaled corticosteroids where appropriate.

Abstract
Background The study investigates which physical performance or muscle function/mass tests significantly correlate with objectively measured physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) and could potentially serve to identify physically inactive COPD patients in routine clinical practice. Methods A cross-sectional, observational study was conducted in outpatients with moderate to very severe COPD. PA was measured during one week with the StepWatch Activity Monitor®, an ankle-worn accelerometer, and expressed in steps per day. Physical fitness and peripheral muscle function/mass were evaluated by the 4-meter gait speed (4MGS) test, the 6-minute walk distance (6MWD), the 30-second chair stand test (30sCST), the timed up and go test (TUGT), handgrip strength, arm muscle area, calf circumference, the fat-free mass index (FFMI), and ultrasound measurement of the quadriceps muscle. Spearman’s rank correlation analysis and ROC analysis were performed. Results The study population (N=111, 69% men, mean age 68 years) walked a mean of 8059 steps/day. The daily step count strongly correlated with the 6MWD (rho=0.684, p<0.001) and moderately with the 4MGS (rho=0.464, p<0.001), the TUGT (rho= −0.463, p<0.001), and the 30sCST (rho=0.402, p<0.001). The correlation with the FFMI was weak (rho=0.210, p=0.027), while the other parameters did not significantly correlate with the daily step count. The 6MWD had the best discriminative power to identify patients with very low PA defined as <5000 steps/day (AUC=0.802 [95% CI: 0.720–0.884], p<0.001), followed by the TUGT, the 4MGS, and the 30sCST. Conclusion The 6MWD, the 4MGS, the TUGT, and the 30sCST are easy to perform in any clinical setting and may be used by clinicians in the screening of physically inactive COPD patients.

Abstract
BACKGROUND The COPD Assessment Test (CAT) has been proposed to help guide therapy in chronic obstructive pulmonary disease (COPD). It is important to understand the distribution of scores in different COPD populations and their determinants. METHODS The POPE study is an international, observational cross-sectional study of COPD subjects in 11 Central and Eastern European countries aimed at characterizing COPD phenotypes. Here we report the analysis of CAT scores with the objective of identifying their determinants, evaluating symptom load and investigating the distribution of scores among the participating countries. Additionally, we investigated the discrepancies between the CAT and modified Medical Research Council (mMRC) scores when used to classify patients according to the GOLD strategy. RESULTS The study included 3452 patients (69.2% men, mean forced expiratory volume in 1 s (FEV1% predicted) 52.5%). The mean CAT score was 17.5 (SD = 7.8), ranging from 15.1 in Hungary to 21.2 in Bulgaria. Multiple linear regression analysis showed six variables significantly associated with CAT scores: depression, number of previous exacerbations, 6-min walking distance, FEV1(%), mMRC and country and explained 47.2% of the variance of CAT. According to either CAT or mMRC, up to 23.9% patients would be classified in different GOLD groups. CONCLUSIONS The CAT score may be predicted by factors related to COPD severity, depression and exercise capacity, with significant differences in the distribution of CAT scores in different countries. According to our results CAT >10 is not equivalent to mMRC >2 for assessing symptom burden. TRIAL REGISTRATION ClinicalTrials.gov, identifier NCT02119494.

Abstract
COPD is a complex, heterogeneous condition. Even in the early clinical stages, COPD carries a significant burden, with breathlessness frequently leading to a reduction in exercise capacity and changes that correlate with long-term patient outcomes and mortality. Implementation of an effective management strategy is required to reduce symptoms, preserve lung function, quality of life, and exercise capacity, and prevent exacerbations. However, current clinical practice frequently differs from published guidelines on the management of COPD. This review focuses on the current scientific evidence and expert opinion on the management of moderate COPD: the symptoms arising from moderate airflow obstruction and the burden these symptoms impose, how physical activity can improve disease outcomes, the benefits of dual bronchodilation in COPD, and the limited evidence for the benefits of inhaled corticosteroids in this disease. We emphasize the importance of maximizing bronchodilation in COPD with inhaled dual-bronchodilator treatment, enhancing patient-related outcomes, and enabling the withdrawal of inhaled corticosteroids in COPD in well-defined patient groups.

Abstract
Chronic obstructive pulmonary disease (COPD) represents a major health problem in Central and Eastern European (CEE) countries; however, there are no data regarding clinical phenotypes of these patients in this region.Participation in the Phenotypes of COPD in Central and Eastern Europe (POPE) study was offered to stable patients with COPD in a real-life setting. The primary aim of this study was to assess the prevalence of phenotypes according to predefined criteria. Secondary aims included analysis of differences in symptom load, comorbidities and pharmacological treatment.3362 patients with COPD were recruited in 10 CEE countries. 63% of the population were nonexacerbators, 20.4% frequent exacerbators with chronic bronchitis, 9.5% frequent exacerbators without chronic bronchitis and 6.9% were classified as asthma-COPD overlap. Differences in the distribution of phenotypes between countries were observed, with the highest heterogeneity observed in the nonexacerbator cohort and the lowest heterogeneity observed in the asthma-COPD cohort. There were statistically significant differences in symptom load, lung function, comorbidities and treatment between these phenotypes.The majority of patients with stable COPD in CEE are nonexacerbators; however, there are distinct differences in surrogates of disease severity and therapy between predefined COPD phenotypes.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) constitutes a major health challenge in Central and Eastern European (CEE) countries. However, clinical phenotypes, symptom load, and treatment habits of patients with COPD in CEE countries remain largely unknown. This paper provides a rationale for phenotyping COPD and describes the methodology of a large study in CEE. Methods/design The POPE study is an international, multicenter, observational cross-sectional survey of patients with COPD in CEE. Participation in the study is offered to all consecutive outpatients with stable COPD in 84 centers across the CEE region if they fulfill the following criteria: age >40 years, smoking history ≥10 pack-years, a confirmed diagnosis of COPD with postbronchodilator FEV1/FVC <0.7, and absence of COPD exacerbation ≥4 weeks. Medical history, risk factors for COPD, comorbidities, lung function parameters, symptoms, and pharmaceutical and nonpharmaceutical treatment are recorded. The POPE project is registered in ClinicalTrials.gov with the identifier NCT02119494. Outcomes The primary aim of the POPE study was to phenotype patients with COPD in a real-life setting within CEE countries using predefined classifications. Secondary aims of the study included analysis of differences in symptoms, and diagnostic and therapeutic behavior in participating CEE countries. Conclusion There is increasing acceptance toward a phenotype-driven therapeutic approach in COPD. The POPE study may contribute to reveal important information regarding phenotypes and therapy in real-life CEE.

Abstract
BACKGROUND Studies suggest that nasal treatment might influence lower airway symptoms and function in patients with comorbid rhinitis and asthma. We investigated the effect of intranasal, inhaled corticosteroid or the combination of both in patients with both pollen-induced rhinitis and asthma. METHODS A total of 262 patients were randomized to 6 weeks' treatment with intranasal fluticasone propionate (INFP) 200 microg o.d., inhaled fluticasone propionate (IHFP) 250 microg b.i.d., their combination, or intranasal or inhaled placebo, in a multicentre, double-blind, parallel-group study. Treatment was started 2 weeks prior to the pollen season and patients recorded their nasal and bronchial symptoms twice daily. Before and after 4 and 6 weeks' treatment, the patients were assessed for lung function, methacholine responsiveness, and induced sputum cell counts. RESULTS Intranasal fluticasone propionate significantly increased the percentages of patients reporting no nasal blockage, sneezing, or rhinorrhoea during the pollen season, compared with IHFP or intranasal or inhaled placebo. In contrast, only IHFP significantly improved morning peak-flow, forced expiratory volume in 1 second (FEV1) and methacholine PD20, and the seasonal increase in the sputum eosinophils and methacholine responsiveness. CONCLUSIONS In patients with pollen-induced rhinitis and asthma, the combination of intranasal and IHFP is needed to control the seasonal increase in nasal and asthmatic symptoms.

Abstract
The aim of this study was to compare the efficacy safety and cost of Seretide (salmeterol/fluticasone propionate (Salm/FP), 50/250 microg bd) via Diskus with formoterol (Form; 12 microg bd) and budesonide (Bud; 800 microg bd) given concurrently (Form+Bud) via Turbuhaler in patients with moderate-to-severe asthma who were uncontrolled on existing corticosteroid therapy. The study used a randomised, double-blind, double-dummy, parallel-group design, consisting of a 2-week run-in period on current corticosteroid therapy (1000-1600 microg/day of BDP or equivalent) and a 12-week treatment period. Symptomatic patients (n = 428) with FEV1 of 50-85% predicted and increased symptom scores or reliever use during run-in were randomly allocated to receive either Salm/FP (50/250 microg bd) via a single Diskus inhaleror Form+Bud (12+800 microg bd) via separate Turbuhalers. Clinic, diary card and asthma-related health-care resource utilisation data were collected. Improvement in mean morning peak expiratory flow (PEFam was similar in the Salm/FP and Form+Bud groups. Both PEFam and mean evening PEF (PEFpm) increased by a clinically significant amount (>20 L/min) from baseline in both treatment groups. The mean rate of exacerbations (mild, moderate or severe) was significantly lower in the Salm/FP group (0.472) compared with the Form+Bud group (0.735) (ratio = 0.64; P < 0.001), despite the three-fold lower microgram inhaled corticosteroid dose in the Salm/FP group. Patients in the Salm/FP group also experienced significantly fewer nocturnal symptoms, with a higher median percentage of symptom-free nights (P = 0.04), nights with a symptom score <2 (P = 0.03), and nights with no awakenings (P = 0.02). Total asthma-related health-care costs were significantly lower in the Salm/FP group than the Form+Bud group (P<0.05). Both treatments were well tolerated, with a similar low incidence of adverse events. This study showed that in symptomatic patients with moderate-to-severe asthma, Salm/FP (50/250 microg bd), administered in a single convenient device (Diskus), was at least as effective as an approximately three-fold higher microgram corticosteroid dose of Bud (800 microg bd) given concurrently with Form (12 microg bd) in terms of improvement in PEFam, and superior at reducing exacerbations and nights with symptoms or night-time awakenings. Salm/FP was also the less costly treatment due primarily to lower hospitalisation and drug costs.

Abstract
There is accumulating evidence that tachykinins are implicated in inflammation, including asthma. Therefore, we hypothesized that the neutral endopeptidase (NEP), under challenge conditions, could be affected. Serum from 21 asthmatics and six healthy volunteers was sampled before, 30, and 120 min after allergen challenge. NEP-IR was determined using an ELISA and was found in all subjects. Compared to prechallenge, no difference was seen between asthmatics and controls; however, under challenge conditions, NEP-IR in asthmatics was significantly lower (30 min, P = 0.058; 120 min, P = 0.0017, respectively). This finding supports indirectly the hypothesis that tachykinins are released during allergen exposure, and suggests a regulatory role of NEP.

Abstract
BACKGROUND Non-specific nasal and bronchial reactivity are frequently correlated in disease (rhinitis and asthma). It is not known whether such a correlation exists in subjects exposed to irritants and in healthy subjects. In order to test the hypothesis that a correlation between non-specific nasal and bronchial reactivity exists in non-asthmatic subjects, two groups of subjects were studied: 110 workers occupationally exposed to respiratory irritants, and 86 non-exposed healthy controls. METHODS Allergy, non-specific nasal, and non-specific bronchial reactivity were tested, and smoking habits were categorized in each subject. RESULTS Respiratory irritants cause a substantial increase in nasal and bronchial reactivity when compared with the group of healthy, non-exposed subjects (33.6% nasal hyperreactors and 20.0% bronchial hyperreactors vs. 4.7% nasal hyperreactors and 2.3% bronchial hyperreactors, respectively). But, occupational exposure to respiratory irritants does not induce a correlation between non-specific nasal and bronchial reactivity frequently found in asthmatic and rhinitic subjects. CONCLUSIONS We found no correlation between non-specific nasal and bronchial reactivity either in subjects occupationally exposed to respiratory irritants or in the group of healthy subjects. This lack of correlation in both studied groups seems to be a feature of non-diseased airways. Smoking as an additional factor does not increase nasal and bronchial reactivity either in workers exposed to irritants or in healthy subjects. Smoking also does not strengthen the correlation between upper and lower airways' reactivity in both groups.

Abstract
Rush immunotherapy (RIT) has been documented as useful in the treatment of patients with allergic bronchial asthma. To investigate the mechanisms of its action, we studied changes in the serum levels of total IgE, allergen-specific IgE and IgG4, and expression of CD23 on peripheral blood B cells in patients receiving RIT. Twenty patients with perennial bronchial asthma were evaluated before the beginning of RIT, as well as 6 weeks and 6 months later. Compared to pretreatment values, the level of Der-p-specific IgG4 and IgE significantly increased after 6 weeks and 6 months of RIT, while the total serum IgE remained unchanged. Furthermore, after 6 months of RIT, the percentage of CD23+B cells and its CD23 receptor density significantly decreased. Since the symptom score improved and the need for medication decreased, we evaluated RIT as a useful procedure. After 6 months, 30% of patients did not have an asthma attack, with no medication in the last month, while 10% of them were asthma free for the last 3 months. No significant correlation between the clinical improvement, and in vitro changes was found. Furthermore, the observed in vitro changes were not significantly different in patients who responded with clinical improvement, compared to those with unchanged intensity of asthma. In conclusion, during specific RIT we found a significant increase in Der-p-specific IgE and IgG4 antibodies, as well as a moderate decrease in CD23+ B cells and its CD23 receptor density. These findings suggest a change in the lymphokine profile of patients receiving specific immunotherapy, and that the inhibition of IL-4-induced B cell stimulation may be hypothesized as the most important mechanism.

Abstract
We investigated the mechanism of the action of volatile anesthetics on the airway smooth muscle constricted by an antigen and leukotriene-D4 (LTD4). Excised tracheal rings from ovalbumin-sensitized guinea pigs were suspended in eight tissue baths. Halothane or isoflurane was aerated into four tissue baths, while the remaining four served as time controls. To assess the antispasmogenic activity of halothane and isoflurane, concentration-response curves for antigen and LTD, were constructed exposed to anesthetics and compared to controls. The spasmolytic activity of halothane and isoflurane was measured in the tracheal rings constricted by a single antigen challenge or by EC50 of LTD. Both halothane and isoflurane produced significant rightward shifts of ovalbumin and LTD, concentration-response curve with corresponding increases in the EC50 values. Halothane increased the EC50 value for LTD, from 5.38 +/- 0.43 x 10-9 M to 1.2 +/- 0.18 x 10-8 M, and for ovalbumin from 1.2 +/- 0.06 x 10-4 mg/ml to 3.03 +/- 0.28 x 10-4 mg/ml. Isoflurane increased the EC50 value for LTD, from 5.17 +/- 0.64 x 10-9 M to 8.98 +/- 1.01 x 10-9 M, and for ovalbumin from 1.21 +/- 0.09 x 10-4 mg/ml to 2.61 +/- 0.19 x 10-4 mg/ml. Furthermore, halothane and isoflurane significantly reduced the magnitude of the antigen-and LTD4-induced constriction. In 30 min intervals, 1% and 2% halothane reduced the magnitude of the ovalbumin-induced constriction by 32% and 50%, respectively, while isoflurane (2% and 4%) caused relaxation of 16% and 35%, respectively. The magnitude of LTD4-induced constriction was reduced by 17% and 24%, with 1% and 2% halothane, respectively. Isoflurane (2% and 4%) reduced this constriction by 25% and 25% respectively. In conclusion, halothane and isoflurane attenuate and prevent the constrictive response of airway smooth muscle to allergen and LTD. A direct, nonspecific dilating effect is suggested as the mechanism responsible for the observed effects.

Abstract
Our previous studies have shown that the inhibition of neutral endopeptidase, an enzyme which degrades tachykinins, increases anaphylactic construction of guinea-pig tracheal smooth muscle. To investigate this observation further, we examined the effects of phosphoramidon, an inhibitor of a neutral endopeptidase, on constriction induced by the non-immunological mast cell degranulator-compound 48/80. Phosphoramidon produced significant leftward shift of the compound 48/80 concentration-response curve with corresponding decrease in the EC50 value from 51 (28-80) micrograms/ml to 42 (20-72) micrograms/ml. When added during the compound 48/80-induced constriction, phosphoramidon significantly increased the magnitude of this constriction by 69.7% after 30 min, and 78.9% after 45 min. Phosphoramidon was ineffective in tracheal rings from tachykinin-depleted guinea pigs. The incubation of tracheal rings with H1-histamine receptor antagonist (diphenhydramine HCl, 10 microM) and leukotriene receptor antagonist (ICI 198.615, 5 microM) significantly diminished the contractile response to compound 48/80 and prevented a phosphoramidon-dependent increase of this constriction. These results suggest that compound 48/80 induces the release of tachykinins by the stimulatory activity of histamine and leukotrienes. Anaphylactic release of tachykinins would therefore not depend directly on the antigen-antibody reaction.

Abstract
To determine whether tachykinins participate in antigen-induced constriction of tracheal smooth muscle, we examined the effects of a neutral endopeptidase inhibitor, phosphoramidon, the tachykinin antagonist (D-Pro4, D-Trp7,9,10)-substance P(4-11), and capsaicin-induced tachykinin depletion on the responses to antigen in tracheal rings from ovalbumin-sensitized guinea pigs. In these preparations, the antigen (ovalbumin, 0.1 microgram/ml) produced reproducible and durable constriction of tracheal smooth muscle. Incubation with phosphoramidon (10 min, 10 microM) prior to antigen challenge significantly augmented the magnitude of ovalbumin-induced constriction by 22% after 30 min and by 31% after 45 min. The addition of phosphoramidon at the plateau level of antigen-induced constriction produced a similar, significant increase in the magnitude of the constriction. Following incubation with tachykinin antagonist (D-Pro4,D-Trp7,9,10)-substance P(4-11) (5 microM), the contractile response of the tracheal rings to the antigen was not altered. Furthermore, the addition of phosphoramidon (10 microM) did not significantly affect this contraction. Similarly, neither tachykinin antagonist nor phosphoramidon altered the ovalbumin-induced constriction of the tracheal rings from capsaicin-treated guinea pigs. Based on these findings, we hypothesize that tachykinins or similar broncho-constricting neutral endopeptidase substrates were released from tachykinin-containing nerve endings during immediate hypersensitivity reaction in airways, manifesting a modest and delayed constrictive effect. Following alteration of endopeptidase activity, these substances could modulate the anaphylactic constriction of the airway smooth muscle.
