Brockway K, Ahmed S. Beyond breathing: Systematic review of global chronic obstructive pulmonary disease guidelines for pain management. Respir Med 2024; 224:107553. [PMID: 38350512 DOI: 10.1016/j.rmed.2024.107553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/15/2024]
Abstract
CONTEXT Patients with chronic obstructive pulmonary disease (COPD) experience pain as both symptom and comorbidity. There has been no evaluation of the recommendations for pain management in updated clinical practice guidelines (CPGs). OBJECTIVES Update the evidence on pain management, determine alignment of pain management recommendations with best-practice, and advocate for optimal pain management in patients with COPD. METHODS PubMed, Guideline International Network, Guideline Portal, Agency for Healthcare Research and Quality, National Institute for Healthcare Excellence, Scottish International Guidelines Network, Institute of Medicine, grey literature, national websites, and bibliographies were searched. CPGs available online for stable COPD produced by organizations representing reputable knowledge of COPD management were included. CPGs unavailable online, not translatable into English, or not including techniques within the defined scope were excluded. Researchers performed frequency counts for the verbatim terms "pain," "physical activity," "exercise," "rehabilitation," "physical therap(ist)/(y), "physiotherap(ist)/(y)," recorded context, and collected recommendations for pain management/treatment when present. RESULTS Of 32 CPGs, 24 included "pain" verbatim. Of these, 13 included recommendations for pain treatment/management. Common recommendations included opioids, pharmacological management, further medical assessment, and surgical intervention. Two CPGs referred to palliative care, one CPG discussed treating cough, and one discussed massage, relaxation, and breathing. CONCLUSIONS Pain management recommendations vary and are not aligned with evidence. Pain should be addressed in patients with COPD, whether directly or indirectly related to the disease. Reduction of variability in pain management and the disease burden is necessary. Pain management should include referrals to providers who can maximize benefit of their services.

Abstract
The Spanish Guideline on the Management of Asthma, better known by its acronym in Spanish GEMA, has been available for more than 20 years. Twenty-one scientific societies or related groups both from Spain and internationally have participated in the preparation and development of the updated edition of GEMA, which in fact has been currently positioned as the reference guide on asthma in the Spanish language worldwide. Its objective is to prevent and improve the clinical situation of people with asthma by increasing the knowledge of healthcare professionals involved in their care. Its purpose is to convert scientific evidence into simple and easy-to-follow practical recommendations. Therefore, it is not a monograph that brings together all the scientific knowledge about the disease, but rather a brief document with the essentials, designed to be applied quickly in routine clinical practice. The guidelines are necessarily multidisciplinary, developed to be useful and an indispensable tool for physicians of different specialties, as well as nurses and pharmacists. Probably the most outstanding aspects of the guide are the recommendations to: establish the diagnosis of asthma using a sequential algorithm based on objective diagnostic tests; the follow-up of patients, preferably based on the strategy of achieving and maintaining control of the disease; treatment according to the level of severity of asthma, using six steps from least to greatest need of pharmaceutical drugs, and the treatment algorithm for the indication of biologics in patients with severe uncontrolled asthma based on phenotypes. And now, in addition to that, there is a novelty for easy use and follow-up through a computer application based on the chatbot-type conversational artificial intelligence (ia-GEMA).

Abstract
Pulmonary function testing (PFT) has a long and rich history in the definition, diagnosis, and management of COPD. For decades, spirometry has been regarded as the standard for diagnosing COPD; however, numerous studies have shown that COPD symptoms, pathology, and associated poor outcomes can occur, despite normal spirometry. Diffusing capacity and imaging studies have called into question the need for spirometry to put the "O" (obstruction) in COPD. The role of exercise testing and the ability of PFTs to phenotype COPD are reviewed. Although PFTs play an important role in diagnosis, treatment decisions are primarily determined by symptom intensity and exacerbation history. Although a seminal study positioned FEV1 as the primary predictor of survival, numerous studies have shown that tests other than spirometry are superior predictors of mortality. In years past, using spirometry to screen for COPD was promulgated; however, this only seems appropriate for individuals who are symptomatic and at risk for developing COPD.

[PMID: 37332323 PMCID: PMC10274847 DOI: 10.2147/clep.s405325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 05/22/2023] [Indexed: 06/20/2023] Open
Abstract
Introduction Although β2-adrenoceptor (β2AR) agonists have been associated with a lower risk of Parkinson's disease (PD), the findings are inconclusive and may reflect confounding by indication. We studied the association between inhaled β2AR agonists and risk of PD in persons with asthma or chronic obstructive pulmonary disease (COPD). Methods The nested case-control study was conducted within a register-based Finnish Parkinson's disease study (FINPARK) and included 1406 clinically verified PD cases diagnosed during 1999-2015, who also had asthma/COPD >3 years before PD. PD cases were matched with up to seven controls by age, sex, duration of asthma/COPD, pulmonary diagnosis, and region (N = 8630). Cumulative and average annual exposure to short- and long-acting β2AR agonists before a 3-year lag period was assessed with quartiles of defined daily doses (DDDs). Adjusted odds ratios (aORs) were calculated with 95% confidence intervals (CIs) using conditional logistic regression. Results Cumulative exposure to either short- or long-acting β2AR agonists was not associated with a risk of PD. With average annual exposure, a decreased risk was observed only for the highest quartile of long-acting β2AR agonists (aOR 0.75; 95% CI 0.58-0.97). In the stratified analysis the lowest risk estimates were observed among those with both asthma and COPD diagnoses. The suggestion of an inverse association was seen for the highest quartile of long-acting β2AR agonists in asthma. Discussion Higher levels of exposure to β2AR agonists were not consistently associated with a reduced risk of PD. The inverse association in the highest category of average annual exposure to long-acting β2AR agonists may be explained by unmeasured confounding, such as disease severity or smoking.

Abstract
This study aims to understand healthcare professionals' thoughts and motivations about optimal management and treatment of patients with chronic obstructive pulmonary disease (COPD). We conducted a DELPHI survey through an online questionnaire distributed to 220 panellists from six European countries and a discrete choice experiment to describe the relationship between selected clinical criteria and the initial COPD treatment of choice. One hundred twenty-seven panellists (general practitioners [GPs] and pulmonologists) completed the survey. Despite the familiarity and use (89.8%) of the GOLD classification for initial treatment selection, a frequent use of LAMA/LABA/ICS was noted. In fact, panellists agreed that inhaled corticosteroids (ICS) are over-prescribed in the primary care setting. Our study showed that GPs felt less confident than pulmonologists with ICS withdrawal. This mismatch observed between best practice and behaviour indicates the need to increase awareness and efforts to improve the adherence to guidelines in clinical practice.

Clinical factors linked to the type of respiratory medication in COPD: results from the COSYCONET cohort. Ther Adv Respir Dis 2023; 17:17534666231208584. [PMID: 37936408 PMCID: PMC10631320 DOI: 10.1177/17534666231208584] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 10/03/2023] [Indexed: 11/09/2023] Open
Abstract
BACKGROUND The use of maintenance medication in patients with chronic obstructive pulmonary disease (COPD) in real life is known to deviate from recommendations in guidelines, which are largely based on randomized controlled trials and selected populations. OBJECTIVES We used the COSYCONET (COPD and Systemic Consequences - Comorbidities Network) cohort to analyze factors linked to the use of COPD drugs under non-interventional circumstances. DESIGN COSYCONET is an ongoing, multi-center, non-interventional cohort of patients with COPD. METHODS Patients with COPD of Global Initiative for Chronic Obstructive Lung Disease (GOLD) grades 0-4 participating in visits 1-5 were included. Data covered the period from 2010 to 2018. Generalized linear models were used to examine the relation of COPD characteristics to different types of respiratory medication. RESULTS A total of 1043 patients were included. The duration of observation was 4.5 years. Use of respiratory medication depended on GOLD grades 0-4 and groups A-D. Long-acting muscarinic antagonist therapy increased over time, and was associated with low carbon monoxide (CO) diffusing capacity, while inhaled corticosteroid (ICS) use decreased. Active smoking was associated with less maintenance therapy in general, and female sex with less ICS use. From the eight items of the COPD Assessment Test, only hill and stair climbing were consistently linked to treatment. CONCLUSION Using data from a large, close to real-life observational cohort, we identified factors linked to the use of various types of respiratory COPD medication. Overall, use was consistent with GOLD recommendations. Beyond this, we identified other correlates of medication use that may help us to understand and improve therapy decisions in clinical practice.

Abstract
Chronic obstructive pulmonary disease (COPD) is a prevalent and long-term airway disease. It has been reported that fucoxanthin (FX) exhibits anti-inflammatory and antioxidant effects. However, the underlying mechanism of FX in COPD remains unknown. Therefore, to investigate the effect of FX on COPD, BEAS-2B cells were treated with cigarette smoke extract (CSE). The viability of BEAS-2B cells treated with increasing doses of FX was assessed by Cell Counting Kit-8. Lactate dehydrogenase (LDH) levels were measured using a corresponding kit. In addition, ELISA was carried out to detect the content of TNF-α, IL-1β and IL-6. Additionally, a TUNEL assay and western blot analysis were performed to assess the cell apoptosis rate. Furthermore, 2',7'-dichlorodihydrofluorescein diacetate was used to measure reactive oxygen species levels, while the contents of oxidative stress-associated indexes were determined using the corresponding kits. Bioinformatics analysis using the search tool for interactions of chemicals database predicted that peroxisome proliferator-activated receptor γ (PPARγ) may be a target of FX. The binding capacity of FTX with PPARγ was confirmed by molecular docking. The protein expression levels of the PPARγ/NF-κB signaling-associated factors were detected by western blot analysis. Finally, the regulatory mechanism of FX in COPD was revealed following cell treatment with the PPARγ inhibitor, T0070907. The results demonstrated that FX enhanced CSE-induced BEAS-2B cell viability and attenuated CSE-induced BEAS-2B cell inflammation and oxidative damage, possibly via triggering PPARγ/NF-κB signaling. Pre-treatment of BEAS-2B cells with the PPARγ inhibitor, T0070907, could reverse the protective effects of FX on CSE-induced BEAS-2B cells. Overall, the present study suggested that FX could ameliorate oxidative damage as well as inflammation in CSE-treated human bronchial epithelial in patients with COPD via modulating the PPARγ/NF-κB signaling pathway.

Abstract
The best therapeutic approach to patients with asthma-chronic obstructive pulmonary disease overlap (ACO) is unknown. Current treatment recommendations rely on expert opinions, roundtable discussions, and strategy documents, because patients with ACO have been excluded from most clinical studies in asthma and COPD. Because of the underlying asthma initial therapy, early use of inhaled corticosteroids along with a long-acting bronchodilator is recommended. If maintenance inhaler therapy is not effective, advanced therapies based on phenotyping and identification of treatable traits may be considered.

Abstract
BACKGROUND Asthma and chronic obstructive pulmonary disease (COPD) are common chronic respiratory diseases, and some patients have overlapping disease features, termed asthma-COPD overlap (ACO). Patients characterized with ACO have increased disease severity; however, the mechanisms driving this have not been widely studied. OBJECTIVES This study sought to characterize the phenotypic and transcriptomic features of experimental ACO in mice induced by chronic house dust mite antigen and cigarette smoke exposure. METHODS Female BALB/c mice were chronically exposed to house dust mite antigen for 11 weeks to induce experimental asthma, cigarette smoke for 8 weeks to induce experimental COPD, or both concurrently to induce experimental ACO. Lung inflammation, structural changes, and lung function were assessed. RNA-sequencing was performed on separated airway and parenchyma lung tissues to assess transcriptional changes. Validation of a novel upstream driver SPI1 in experimental ACO was assessed using the pharmacological SPI1 inhibitor, DB2313. RESULTS Experimental ACO recapitulated features of both asthma and COPD, with mixed pulmonary eosinophilic/neutrophilic inflammation, small airway collagen deposition, and increased airway hyperresponsiveness. Transcriptomic analysis identified common and distinct dysregulated gene clusters in airway and parenchyma samples in experimental asthma, COPD, and ACO. Upstream driver analysis revealed increased expression of the transcription factor Spi1. Pharmacological inhibition of SPI1 using DB2313, reduced airway remodeling and airway hyperresponsiveness in experimental ACO. CONCLUSIONS A new experimental model of ACO featuring chronic dual exposures to house dust mite and cigarette smoke mimics key disease features observed in patients with ACO and revealed novel disease mechanisms, including upregulation of SPI1, that are amenable to therapy.

Abstract
Asthma-COPD overlap (ACO) is a heterogeneous condition that describes patients who show persistent airflow limitation with clinical features that support both asthma and COPD. Although no single consensus definition exists to diagnose this entity, common major criteria include a strong bronchodilator reversibility or bronchial hyperreactivity, a physician diagnosis of asthma, and a ≥ 10-pack-year cigarette smoking history. The prevalence of ACO ranges from 0.9% to 11.1% in the general population, depending on the diagnostic definition used. Notably, patients with ACO experience greater symptom burden, worse quality of life, and more frequent and severe respiratory exacerbations than those with asthma or COPD. The underlying pathophysiologic features of ACO have been debated. Although emerging evidence supports the role of environmental and inhalational exposures in its pathogenesis among patients with a pre-existing airway disease, biomarker profiling and genetic analyses suggest that ACO may be a heterogeneous condition, but with definable characteristics. Early-life factors including childhood-onset asthma and cigarette smoking may interact to increase the risk of airflow obstruction later in life. For treatment options, the population with ACO historically has been excluded from therapeutic trials; therefore strong, evidence-based recommendations are lacking beyond first-line inhaler therapies. Advanced therapies in patients with ACO are selected according to disease phenotypes and are based on extrapolated data from asthma and COPD. Research focused on defining biomarkers and evidence-based treatment options for ACO is needed urgently.

Abstract
AIMS The aim of this study was to determine what kinds of unmet information needs people with COPD have and whether there are differences in information needs between genders or based on the time since COPD diagnosis. DESIGN A descriptive cross-sectional study. METHODS Data on people with COPD (N = 169) were collected from a two-part questionnaire distributed via website. On the first part, information needs concerning the medical aspects of self-management were measured by the Lung Information Needs Questionnaire (LINQ). On the second part, which was developed specifically for this study, a more holistic view of self-management counselling was sought. Statistical methods were used to analyse the data. RESULTS The respondents had wide-ranging information needs in many areas of COPD self-management. The most often reported areas of unmet information needs included exacerbations, diet, fatigue, stress and anxiety, palliative care and sexual life. The information needs varied by gender and time since COPD diagnosis.

Abstract
OBJECTIVE This study set out to investigate the effect of budesonide combined with salbutamol nebulization on pulmonary function and serum immune factors in children with bronchiolitis. METHODS A total of 127 children with bronchiolitis who were treated in our hospital were collected. Among them, 59 were treated with conventional bronchiolitis and were included in the control group (CG), and 68 were treated by budesonide combined with salbutamol inhalation in addition to the conventional treatment that were included in the research group (RG). The clinical efficacy, disappearance time of cough, pulmonary rales, wheezing and dyspnea, hospitalization time, adverse reactions, lung function and serum immune factors of the two groups were compared. RESULTS Compared with before treatment, cough, pulmonary rales, wheezing and dyspnea of children in both groups were improved after treatment. Compared with the CG, the disappearance time of cough, pulmonary rales, wheezing and dyspnea in the RG was shortened, the hospitalization time and adverse reactions reduced, and the total effective rate increased. The tidal volume, peak-to-peak time ratio (tPTEF/tE) and peak-to-peak volume ratio (VPTEF/VE) of the RG were dramatically better than those of the CG, and the levels of IgG, IgM and IgA were better than those of the CG. CONCLUSION Budesonide combined with salbutamol nebulization is beneficial to improve the pulmonary function and serum immune factors in children with bronchiolitis.

Abstract
Although chronic obstructive pulmonary disease (COPD) and asthma are well-characterized diseases, they can coexist in a given patient. The term asthma-COPD overlap (ACO) was introduced to describe patients that have clinical features of both diseases and may represent around 25% of COPD patients and around 20% of asthma patients. Despite the increasing interest in ACO, there are still substantial controversies regarding its definition and its position within clinical guidelines for patients with obstructive lung disease. In general, most definitions indicate that ACO patients must present with non-reversible airflow limitation, significant exposure to smoking or other noxious particles or gases, together with features of asthma. In patients with a primary diagnosis of COPD, the identification of ACO has therapeutic implication because the asthmatic component should be treated with inhaled corticosteroids and some studies suggest that the most severe patients may respond to biological agents indicated for severe asthma. This manuscript aims to summarize the current state-of-the-art of ACO. The definitions, prevalence, and clinical manifestations will be reviewed and some innovative aspects, such as genetics, epigenetics, and biomarkers will be addressed. Lastly, the management and prognosis will be outlined as well as the position of ACO in the COPD and asthma guidelines.

Abstract
Chronic obstructive pulmonary disease (COPD) is a disease with increasing prevalence and burden for health systems worldwide. Every country collects its own epidemiological data regarding COPD prevalence, morbidity and mortality while taking steps to educate the population and medical community to improve early detection and treatment. The rising COPD prevalence creates a need for comprehensive guidelines. In 2012 and 2017–2018, the Romanian Society of Pneumology (SRP) organised national inquiries for COPD, while lung physicians in Romania began receiving education regarding the correct algorithms for COPD diagnosis and therapy. During 2019, a Romanian clinical guideline for diagnosis and treatment of COPD was published, and a condensed version of key points from this guideline are presented herein. COPD is diagnosed based on the presence of three major components: relevant exposure history, respiratory symptoms, and airway limitation that is not fully reversible. Clinical evaluation of patients diagnosed with COPD should include the level of symptoms, exacerbation rate, the presence of comorbidities and determination of phenotypes. The present abridged guideline is designed to be accessible and practical for assessing and managing patients with COPD. The application of up-to-date COPD guidelines may enhance the optimism of physicians and patients in managing this disease.

Abstract
BACKGROUND Asthma and chronic obstructive pulmonary disease (COPD) are common comorbidities in persons with Alzheimer's disease (AD). However, pharmacotherapy of these diseases may have opposite mechanisms of action; anticholinergics in asthma/COPD and acetylcholinesterase inhibitors (AChEI) in AD. OBJECTIVE To investigate whether existing asthma/COPD affects the choice of AD medication, and the survival of the patients with AD. METHODS In this retrospective cohort study, data from the MEDALZ-study, which includes all community-dwelling persons with AD during 2005-2011 in Finland (n = 70718) was utilized. Persons with asthma/COPD (N = 7211) were defined as having a special reimbursement for asthma/COPD, or long-term use (≥250 days) of inhaled anticholinergics, inhaled corticosteroids, or leukotriene antagonists during the year before AD diagnosis. We compared persons with and without asthma/COPD regarding the choice of the initial antidementia medication (AChEI versus memantine) with logistic regression and mortality with Cox regression model during the follow-up (up to end of 2015). RESULTS Memantine was favored over AChEIs as first-line treatment to AD in persons with asthma/COPD compared to those without asthma/COPD (odds ratio 1.23, 95% confidence interval (CI) 1.15-1.31). Memantine was also more commonly used among those who used multiple asthma/COPD medications (7.9% of memantine initiators used ≥3 asthma/COPD medications compared with 5.5% of those who initiated with AChEI). Mortality was higher in persons with asthma/COPD compared to those without asthma/COPD (adjusted hazard ratio 1.10, 95% CI 1.07-1.13). CONCLUSION More frequent use of memantine instead of AChEI may result from an attempt to prevent possible worsening of asthma/COPD by AChEIs. Vulnerable persons with both AD and asthma/COPD need individually assessed pharmacotherapy for their medical conditions.

Abstract
Inclusion of a pharmacist showed that pharmacy-led patient education can positively impact treatment outcome, chronic obstructive pulmonary disease (COPD) knowledge, medication adherence, quality of life, significant reduction in hospital admission rates, and emergency department visits. The objectives were to assess the degree of COPD knowledge in Lebanese community pharmacists as well as their attitudes and practice toward disease management. Between January and May 2018, a cross-sectional survey enrolled 709 Lebanese community pharmacists. A committee was created to build up the questionnaire; it was composed of two physicians (one infectious disease specialist and one pulmonologist) and eight pharmacists, with long expertise in community and hospital pharmacy. It comprised 12 questions assessing knowledge, 12 questions for attitude, and 13 questions for practice. Higher attitude (β = 0.56) and higher practice (β = 0.41) were associated with higher knowledge score. Higher knowledge (β = 0.10) and practice (β = 0.16) scores as well as female gender (β = 0.60) were significantly associated with higher attitude scores. Higher knowledge (β = 0.13) and higher attitude (β = 0.19) showed significant association with higher practice scores. Female gender (β = −0.94), however, was significantly associated with decreased practice score. Our study highlights the importance of assessing the capabilities of pharmacists of achieving their support role in COPD patients. In order to improve community pharmacists’ knowledge of COPD, ultimately improving patient outcomes, further education is crucial.

Abstract
Pathological features of both asthma and COPD coexist in some patients and this is termed asthma-COPD overlap (ACO). ACO is heterogeneous and patients exhibit various combinations of asthma and COPD features, making it difficult to characterise the underlying pathogenic mechanisms. There are no controlled studies that define effective therapies for ACO, which arises from the lack of international consensus on the definition and diagnostic criteria for ACO, as well as scant in vitro and in vivo data. There remain unmet needs for experimental models of ACO that accurately recapitulate the hallmark features of ACO in patients. The development and interrogation of such models will identify underlying disease-causing mechanisms, as well as enabling the identification of novel therapeutic targets and providing a platform for assessing new ACO therapies. Here, we review the current understanding of the clinical features of ACO and highlight the approaches that are best suited for developing representative experimental models of ACO. Understanding the pathogenesis of asthma-COPD overlap is critical for improving therapeutic approaches. We present current knowledge on asthma-COPD overlap and the requirements for developing an optimal animal model of disease.https://bit.ly/3lsjyvm

Abstract
This position paper has been drafted by experts from the Czech national board of diseases with bronchial obstruction, of the Czech Pneumological and Phthisiological Society. The statements and recommendations are based on both the results of randomized controlled trials and data from cross-sectional and prospective real-life studies to ensure they are as close as possible to the context of daily clinical practice and the current health care system of the Czech Republic. Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable heterogeneous syndrome with a number of pulmonary and extrapulmonary clinical features and concomitant chronic diseases. The disease is associated with significant mortality, morbidity and reduced quality of life. The main characteristics include persistent respiratory symptoms and only partially reversible airflow obstruction developing due to an abnormal inflammatory response of the lungs to noxious particles and gases. Oxidative stress, protease-antiprotease imbalance and increased numbers of pro-inflammatory cells (mainly neutrophils) are the main drivers of primarily non-infectious inflammation in COPD. Besides smoking, household air pollution, occupational exposure, low birth weight, frequent respiratory infections during childhood and also genetic factors are important risk factors of COPD development. Progressive airflow limitation and airway remodelling leads to air trapping, static and dynamic hyperinflation, gas exchange abnormalities and decreased exercise capacity. Various features of the disease are expressed unequally in individual patients, resulting in various types of disease presentation, emerging as the "clinical phenotypes" (for specific clinical characteristics) and "treatable traits" (for treatable characteristics) concept. The estimated prevalence of COPD in Czechia is around 6.7% with 3,200-3,500 deaths reported annually. The elementary requirements for diagnosis of COPD are spirometric confirmation of post-bronchodilator airflow obstruction (post-BD FEV1/VCmax <70%) and respiratory symptoms assessement (dyspnoea, exercise limitation, cough and/or sputum production. In order to establish definite COPD diagnosis, a five-step evaluation should be performed, including: 1/ inhalation risk assessment, 2/ symptoms evaluation, 3/ lung function tests, 4/ laboratory tests and 5/ imaging. At the same time, all alternative diagnoses should be excluded. For disease classification, this position paper uses both GOLD stages (1 to 4), GOLD groups (A to D) and evaluation of clinical phenotype(s). Prognosis assessment should be done in each patient. For this purpose, we recommend the use of the BODE or the CADOT index. Six elementary clinical phenotypes are recognized, including chronic bronchitis, frequent exacerbator, emphysematous, asthma/COPD overlap (ACO), bronchiectases with COPD overlap (BCO) and pulmonary cachexia. In our concept, all of these clinical phenotypes are also considered independent treatable traits. For each treatable trait, specific pharmacological and non-pharmacological therapies are defined in this document. The coincidence of two or more clinical phenotypes (i.e., treatable traits) may occur in a single individual, giving the opportunity of fully individualized, phenotype-specific treatment. Treatment of COPD should reflect the complexity and heterogeneity of the disease and be tailored to individual patients. Major goals of COPD treatment are symptom reduction and decreased exacerbation risk. Treatment strategy is divided into five strata: risk elimination, basic treatment, phenotype-specific treatment, treatment of respiratory failure and palliative care, and treatment of comorbidities. Risk elimination includes interventions against tobacco smoking and environmental/occupational exposures. Basic treatment is based on bronchodilator therapy, pulmonary rehabilitation, vaccination, care for appropriate nutrition, inhalation training, education and psychosocial support. Adequate phenotype-specific treatment varies phenotype by phenotype, including more than ten different pharmacological and non-pharmacological strategies. If more than one clinical phenotype is present, treatment strategy should follow the expression of each phenotypic label separately. In such patients, multicomponental therapeutic regimens are needed, resulting in fully individualized care. In the future, stronger measures against smoking, improvements in occupational and environmental health, early diagnosis strategies, as well as biomarker identification for patients responsive to specific treatments are warranted. New classes of treatment (inhaled PDE3/4 inhibitors, single molecule dual bronchodilators, anti-inflammatory drugs, gene editing molecules or new bronchoscopic procedures) are expected to enter the clinical practice in a very few years.

Abstract
BACKGROUND Triple therapy consisting of a drug association including an inhaled corticosteroid, a long-acting muscarinic receptor antagonist and a long-acting β2-adrenergic agonist, delivered via a single device, can be a valuable treatment for chronic obstructive pulmonary disease (COPD) patients experiencing frequent disease exacerbations. OBJECTIVES The aim of this real-life, single-center, observational study was to evaluate, in 44 COPD patients with recurrent exacerbations, the effects of the triple inhaled therapy combining fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI). METHODS Within such a therapeutic context, several clinical and lung functional parameters were considered at baseline and after 24 weeks of treatment with combined inhaled triple therapy. RESULTS With respect to baseline, after 24 weeks of treatment with FF/UMEC/VI, significant changes were recorded with regard to Modified British Medical Research Council (p < 0.0001) and COPD Assessment Test (p < 0.0001) scores, COPD exacerbations (p < 0.001), forced expiratory volume in the first second (p < 0.001), residual volume (p < 0.01), forced mid-expiratory flow between 25 and 75% of FVC (p < 0.0001), inspiratory capacity (p < 0.01), forced vital capacity (p < 0.05), and peak expiratory flow (p < 0.0001). Moreover, in a subgroup of 28 patients, a significant increase of diffusion lung capacity (p < 0.01) was also detected. CONCLUSIONS In conclusion, our real-life results suggest that triple inhaled therapy with FF/UMEC/VI, when given to COPD patients with frequent exacerbations, is able to positively impact on dyspnea and global health status as well as to significantly decrease COPD exacerbations and improve airflow limitation and lung hyperinflation.

Abstract
BACKGROUND Possible variation in bronchodilator response (BDR) according to age at the diagnosis of adult-onset asthma is unknown. Our aim was to assess if BDR in FEV1 is related to age at diagnosis of adult-onset asthma and how many subjects fulfill the 400 mL criterion of BDR, the suggested cut-off for asthma-like reversibility in asthma-COPD overlap (ACO). METHODS A total of 1030 patients with adult-onset asthma were included; 245 from SAAS (Seinäjoki Adult Asthma Study, Finland) and 785 from COREA (Cohort for Reality and Evolution of Adult Asthma in Korea) cohorts. BDR in FEV1 at the diagnosis of asthma was assessed. Patients were divided into groups based on age at asthma diagnosis: < 40, 40-59.9, and ≥ 60 years. The cohorts were analyzed separately. RESULTS BDR % in FEV1 did not differ between the groups of different age at asthma diagnosis and no correlation between BDR and age was found. Of patients aged ≥40 years, only 18% (SAAS-cohort) and 5% (COREA-cohort) reached the 400 mL BDR in FEV1. After exclusion of possible ACO patients, the results remained similar. CONCLUSION By using two large cohorts of steroid-naive patients with asthma, we have shown that BDR at diagnosis of asthma is constant over large age span range, and the limit of 400 mL in BDR in FEV1 is rarely reached. TRIAL REGISTRATION Seinäjoki Adult Asthma Study is registered at ClinicalTrials.gov with identifier number NCT02733016 .

Abstract
We studied whether fractional exhaled nitric oxide (F ENO) can differentiate chronic obstructive pulmonary disease (COPD) with concurrent diagnosis of asthma from COPD-only as well as its ability to predict disease severity and progression. This study was embedded in the Canadian Cohort Obstructive Lung Disease (CanCOLD). Subjects of ≥40 years old completed F ENO measurements were subdivided into four groups, including COPD (N = 86 [COPD-only (N = 35) and COPD with concurrent diagnosis of asthma (N = 51)], healthy (N = 72), and at risk (N = 151). Three of the most common clinical definitions were used for characterizing COPD with concurrent diagnosis of asthma: 1) atopy and self-reported physician diagnosis of asthma, 2) ≥12% and ≥200 ml post-bronchodilator FEV1; 3) self-reported physician diagnosis of asthma. F ENO values were classified using quartiles and the American Thoracic Society (ATS) guideline 2011. Compared to COPD-only, more COPD with concurrent diagnosis of asthma had a significant F ENO50 level of [Formula: see text] 33.5 ppb (fourth quartile) than COPD-only (p = 0.045, 0.011, and 0.006, for definition 1, 2, and 3, respectively). Considering the ATS guideline 2011, fewer COPD with concurrent diagnosis of asthma had F ENO50 < 25 than COPD-only, which was statistically significant with definition 1 and 3 (p = 0.038 and 0.026, respectively). F ENO as a biomarker has the potential to be used as a complementary value for differentiating COPD with concurrent diagnosis of asthma from COPD-only. Further studies should be conducted on validated definitions of COPD with concurrent diagnosis of asthma, which may include a reference to the type of airway inflammation in addition to the clinical definition.

Abstract
BACKGROUND AND PURPOSE Chronic obstructive pulmonary disease, encompassing chronic airway obstruction and lung emphysema, is a major worldwide health problem and a severe socio-economic burden. Evidence previously provided by our group has shown that inhibition of inducible NOS (iNOS) prevents development of mild emphysema in a mouse model of chronic tobacco smoke exposure and can even trigger lung regeneration. Moreover, we could demonstrate that pulmonary hypertension is not only abolished in cigarette smoke-exposed iNOS-/- mice but also precedes emphysema development. Possible regenerative effects of pharmacological iNOS inhibition in more severe models of emphysema not dependent on tobacco smoke, however, are hitherto unknown. EXPERIMENTAL APPROACH We have established a mouse model using a single dose of porcine pancreatic elastase or saline, intratracheally instilled in C57BL/6J mice. Emphysema, as well as pulmonary hypertension development was determined by both structural and functional measurements. KEY RESULTS Our data revealed that (i) emphysema is fully established after 21 days, with the same degree of emphysema after 21 and 28 days post instillation, (ii) emphysema is stable for at least 12 weeks and (iii) pulmonary hypertension is evident, in contrast to smoke models, only after emphysema development. Oral treatment with the iNOS inhibitor N(6)-(1-iminoethyl)-l-lysine (L-NIL) was started after emphysema establishment and continued for 12 weeks. This resulted in significant lung regeneration, evident in the improvement of emphysema and reversal of pulmonary hypertension. CONCLUSION AND IMPLICATIONS Our data indicate that iNOS is a potential new therapeutic target to treat severe emphysema and associated pulmonary hypertension.

Abstract
Objective: To find out how regularly the contents of patient education regarded as essential for COPD patients' self-management are provided by healthcare professionals in specialised healthcare (SHC) and primary healthcare (PHC) in Finland.Design: A cross-sectional study based on an e-questionnaire with 42 items on the content of self-management education of COPD patients.Setting: The study sample included all public SHC units with pulmonary outpatient clinics (n = 29) and nine out of 160 health centres in Finland.Subjects: 83 doctors and 162 nurses.Main outcome measures: The respondents' answers on how regularly they included the contents regarded as essential for COPD patients' self-management in their education of COPD patients.Results: COPD patients were educated regularly on medical issues regarding COPD treatment, such as smoking cessation, exercise and pharmacological treatment. However, issues vital for coping with the disease, such as psychological well-being, stress management or fatigue, were often ignored. Patient education in SHC seemed to be more systematic than education in PHC. The education provided by the asthma/COPD nurses (n = 70) was more systematic than the education provided by the other nurses (n = 84).Conclusion: Healthcare professionals' continuous education should cover not only the medical but also the psychosocial aspects of coping with COPD. The role of doctors and nurses should be considered to ensure that there is no gap in COPD patients' education. Training asthma/COPD nurses and promoting specialised nurse-led asthma/COPD clinics in primary care could be beneficial while improving practices of patient education that enhance patients' ability to cope with the disease.KEY POINTSIssues vital for coping with chronic obstructive pulmonary disease (COPD), such as psychological well-being, stress and fatigue, are irregularly included in self-management education both in primary and specialised healthcare.Patient education provided by asthma/COPD nurses is more regular than patient education provided by other nurses.The distribution of work between doctors and nurses should be considered to ensure that there is no gap in COPD patients' education.

Abstract
BACKGROUND AND OBJECTIVE Lack of consensus on diagnosis of ACO limits our understanding of the impact, management and outcomes of ACO. The present observational study aims to describe the prevalence, clinical characteristics and course of individuals with ACO based on various definitions used in clinical practice. METHODS We included individuals with COPD from the prospective, multisite CanCOLD study and defined subjects with ACO using seven definitions commonly used in the literature. RESULTS Data including questionnaires, lung function and CT scans were analysed from 522 individuals with COPD who were randomly recruited from the population. Among them, 264 fulfilled at least one of the seven definitions of ACO. Prevalence of ACO varied from 3.8% to 31%. Regardless of the definition, individuals with ACO had worse outcomes (lung function and higher percentage of fast decliners, symptoms and exacerbations, health-related quality of life and comorbidities) than the remaining patients with COPD. Conversely, patients with non-ACO had higher emphysema and bronchiolitis scores. The three definitions that included atopy and/or physician diagnosis of asthma identified subjects who differed significantly from patients with COPD. The two ACO definitions with post-bronchodilator reversibility were concordant with COPD and were the least stable, with less than 50% of the patients from each group maintaining reversibility over visits. CONCLUSION Atopy and physician-diagnosed asthma are more distinguishing characteristics to identify ACO. This finding needs to be validated using measures of airway inflammation and other specific biomarkers.

Abstract
Importance Asthma, a chronic inflammatory airway disease, and atrial fibrillation (AF) share several common pathophysiological mechanisms. Research on the association between asthma and atrial fibrillation is lacking, and to our knowledge, no previous studies have assessed the dose-response association between levels of asthma control and AF. Objective To assess the association between asthma, levels of asthma control, and AF. Design, Setting, and Participants This prospective population cohort analyzed data on adults from a second and third iteration of the survey-based Nord-Trøndelag Health Study (HUNT) in Norway. All included participants were free from AF at baseline. Atrial fibrillation was ascertained by linking HUNT data with hospital records from the 2 hospitals in Nord-Trøndelag County. Data analysis was completed from May 2017 to November 2017. Exposures Self-reported asthma was categorized into 3 groups: those who had ever had asthma, those who self-report being diagnosed with asthma, and those who had active asthma. Asthma control was defined according to Global Initiative for Asthma guidelines and was categorized into controlled, partly controlled, and uncontrolled cases. Main Outcomes and Measures Atrial fibrillation. Results A total of 54 567 adults were included (of whom 28 821 [52.8%] were women). Of these, 5961 participants (10.9%) reported ever having asthma, 3934 participants (7.2%) reported being diagnosed with asthma, and 2485 participants (4.6%) reported having active asthma. During a mean (SD) follow-up of 15.4 (5.8) years, 2071 participants (3.8%) developed AF. Participants with physician-diagnosed asthma had an estimated 38% higher risk of developing AF (adjusted hazard ratio, 1.38 [95% CI, 1.18-1.61]) compared with participants without asthma. There was a dose-response association between levels of asthma control and risk of AF with the highest risk for AF in participants with uncontrolled asthma (adjusted hazard ratio, 1.74 [95% CI, 1.26-2.42]; P for trend < .001). Conclusions and Relevance Asthma and lack of asthma control were associated with moderately increased risks of AF in a dose-response manner. Further studies are needed to explore the underlying mechanisms and clarify causal pathways between asthma and AF.

Abstract
BACKGROUND The Evaluating Respiratory Symptoms in Chronic Obstructive Pulmonary Disease (E-RS:COPD) is a patient-reported diary that assesses respiratory symptoms in stable COPD. METHODS This post hoc analysis of a randomized, double-blind, parallel-arm trial (GSK ID: 200699; NCT02164539) assessed the structure, reliability, validity and responsiveness of the E-RS, and a separate wheeze item, for use in patients with a primary diagnosis of asthma or COPD, but with spirometric characteristics of both (fixed airflow obstruction and reversibility to salbutamol; a subset of patients referred to as spirometric asthma-COPD overlap [ACO]; N = 338). RESULTS Factor analysis demonstrated that E-RS included Cough and Sputum, Chest Symptoms, and Breathlessness domains, with a Total score suitable for quantifying overall respiratory symptoms (comparative fit index: 0.9), consistent with the structure shown in COPD. The wheeze item did not fit the model. Total and domain scores were internally consistent (Cronbach's alpha: 0.7-0.9) and reproducible (intra-class correlations > 0.7). Moderate correlations between RS-Total and RS-Breathlessness scores were observed with St George's Respiratory Questionnaire (SGRQ) Total and Activity domain scores at baseline (r = 0.43 and r = 0.48, respectively). E-RS scores were sensitive to change when a patient global impression of change and SGRQ change scores were used to define responders, with changes of ≥ - 1.4 in RS-Total score interpreted as clinically meaningful. CONCLUSIONS E-RS:COPD scores were reliable, valid and responsive in this sample, suggesting the measure may be suitable for evaluating the severity of respiratory symptoms and the effects of treatment in patients with asthma and COPD that exhibit spirometric characteristics of both fixed airflow obstruction and reversibility. Further study of this instrument and wheeze in new samples of patients with ACO is warranted.

Abstract
Background Exposure to environmental particulate matter (PM) ≤2.5 μm in diameter (PM2.5) and smoking are common contributors to COPD, and pertinent research implicates both factors in pulmonary inflammation. Using in vivo mouse and in vitro human cellular models, we investigated the joint impact of PM2.5 pollution, and cigarette smoke (CS) in mice or cigarette-smoke extract (CSE) in cells on COPD inflammation, and explored potential mechanisms. Methods Tissue changes in lungs of C57BL/6 mice exposed to PM2.5 and CS were studied by light microscopy, H&E, immunochemistry, and immunofluorescence-stained sections. Levels of inflammatory factors induced by PM2.5/CS in mice and PM2.5/CSE in 16HBE cells were also monitored by quantitative reverse-transcription (qRT)-PCR and ELISA. Expression of genes related to the Wnt5a-signaling pathway was assessed at transcriptional and protein levels using immunofluorescence, qRT-PCR, and Western blotting. Results Inflammatory response to combined exposure of PM2.5 and CS or CSE in mouse and 16HBE cells surpassed responses incited separately. Although separate PM2.5 and CS/CSE exposure upregulated the expression of Wnt5a (a member of the Wnt-secreted glycoprotein family), combined PM2.5 and CS/CSE exposure produced a steeper rise in Wnt5a levels. Use of a Wnt5a antagonist (BOX5) successfully blocked related inflammatory effects. ERK phosphorylation appeared to mediate the effects of Wnt5a in the COPD model, promoting PM2.5 aggravation of CS/CSE-induced airway inflammation. Conclusion Our findings suggest that combined PM2.5 and CS/CSE exposure induce airway inflammation and Wnt5a expression in vivo in mice and in vitro in 16HBE cells. Furthermore, PM2.5 seems to aggravate CS/CSE-induced inflammation via the Wnt5a–ERK pathway in the context of COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the leading causes of mortality around the world. COPD is characterised by a heterogeneous clinical presentation and prognosis which may vary according to the clinical phenotype. One of the phenotypes of COPD most frequently studied is the asthma-COPD overlap (ACO), however, there are no universally accepted diagnostic criteria for ACO. It is recognised that the term ACO includes patients with clinical features of both asthma and COPD, such as more intense eosinophilic bronchial inflammation, more severe respiratory symptoms and more frequent exacerbations, but in contrast, it is associated with a better prognosis compared to COPD. More importantly, ACO patients show better response to inhaled corticosteroid treatment than other COPD phenotypes. The diagnosis of ACO can be difficult in clinical practice, and the identification of these patients can be a challenge for non-specialized physicians. We describe how to recognise and diagnose ACO based on a recently proposed Spanish algorithm and by the analysis of three clinical cases of patients with COPD. The diagnosis of ACO is based on the diagnosis of COPD (chronic airflow obstruction in an adult with significant smoking exposure), in addition to a current diagnosis of asthma and/or signficant eosinophilia.

Abstract
Chronic pain is highly prevalent and more common in people with chronic obstructive pulmonary disease (COPD) than people of similar age/sex in the general population. This systematic review aimed to describe how frequently and in which contexts pain is considered in the clinical practice guidelines (CPGs) for the broad management of COPD. Databases (Medline, Scopus, CiNAHL, EMbase, and clinical guideline) and websites were searched to identify current versions of COPD CPGs published in any language since 2006. Data on the frequency, context, and specific recommendations or strategies for the assessment or management of pain were extracted, collated, and reported descriptively. Of the 41 CPGs (English n = 20) reviewed, 16 (39%) did not mention pain. Within the remaining 25 CPGs, pain was mentioned 67 times (ranging from 1 to 10 mentions in a single CPG). The most frequent contexts for mentioning pain were as a potential side effect of specific pharmacotherapies (22 mentions in 13 CPGs), as part of differential diagnosis (14 mentions in 10 CPGs), and end of life or palliative care management (7 mentions in 6 CPGs). In people with COPD, chronic pain is common; adversely impacts quality of life, mood, breathlessness, and participation in activities of daily living; and warrants consideration within CPGs for COPD.

Abstract
We performed a meta-analysis to compare the impact of triple combination therapy with inhaled corticosteroids (ICS), long-acting β2-agonists (LABAs) and long-acting muscarinic receptor antagonists (LAMAs) versus LABA/LAMA combination therapy or single long-acting bronchodilator therapy in chronic obstructive pulmonary disease. The ICS/LABA/LAMA combination reduced the risk of exacerbation (relative risk 0.70, 95% CI 0.53-0.94) and improved trough forced expiratory volume in 1 s (mean difference in mL +37.94, 95% CI 18.83-53.89) versus LABA/LAMA combination therapy. The protective effect of triple combination therapy versus LABA/LAMA combination therapy against risk of exacerbation was greater in patients with blood eosinophil counts ≥300 cells·µL-1 (relative risk 0.57, 95% CI 0.48-0.68). While ∼38 patients had to be treated for 1 year with ICS/LABA/LAMA combination therapy to prevent one exacerbation compared to LABA/LAMA combination therapy, the number needed to treat (NNT) was ∼21 when compared to single long-acting bronchodilator therapy. The person-based NNT per year of ICS/LABA/LAMA combination therapy versus LABA/LAMA combination therapy was significantly (p<0.05) lower in patients with eosinophil counts ≥300 cells·µL-1 (NNT value: 8.58) than in those with counts <300 cells·µL-1 (NNT value: 46.28). The risk of pneumonia did not differ between ICS/LABA/LAMA combination therapy and its comparators. The number needed to harm was ∼195. This meta-analysis suggests that patients on single long-acting bronchodilator therapy or LABA/LAMA combination therapy, who still have exacerbations and have blood eosinophil counts ≥300 cells·µL-1, could benefit from ICS/LABA/LAMA combination therapy.

Abstract
Asthma-COPD overlap (ACO) is a type of incomplete obstructive airway disease that has a high incidence and mortality. Nevertheless, there is currently no clear definition of ACO and no effective intervention. The newly discovered phosphodiesterase-4 inhibitor, roflumilast, has shown initial efficacy for treating asthma, COPD, and ACO. The mechanism of roflumilast, however, remains unclear, and there has been no interpretation through systematic review to date. The determination of a definite mechanism of roflumilast will guide the clinician's decisions regarding medication use, standardized diagnosis, and treatment guidelines. For this reason, we have systematically reviewed the therapeutic mechanism of roflumilast for ACO and provided reference for the clinical application of roflumilast in ACO.

Abstract
Background and purpose COPD is one of the leading causes of morbidity and mortality worldwide. Although medication counseling interventions by pharmacists have been found to support the management of COPD, little is known about pharmacists’ knowledge concerning COPD and regular practices and perceptions concerning medication counseling of COPD patients. The purpose of this study was to research these topics among Finnish community pharmacists. Materials and methods In January 2017, an electronic survey was e-mailed to Finnish community pharmacies (n=741) via the Association of the Finnish Pharmacies. One pharmacist from each pharmacy, preferably a specialist in asthma, was invited to answer the survey. Results Completed responses were received from 263 pharmacists (response rate =35%), of whom 196 pharmacists were specialists in asthma. Response rate among asthma pharmacists was 42%. Pharmacists were positive about their role in medication counseling and in support of the self-management of COPD patients. COPD-related knowledge was self-assessed as being good and was on a good level in respect of basic facts. However, almost half (46%) of the pharmacists did not know that COPD is considered a national public health issue, and ~50% of the pharmacists were not familiar with the current care guideline on COPD. Medication counseling was found to be more medicinal product-driven and less advisory concerning lifestyle changes such as smoking cessation and physical exercise. Conclusion Although the pharmacists’ knowledge of COPD was good on general topics, there were some gaps in their knowledge on the current care guideline and status of the disease. Pharmacists should more systematically individually target medication counseling according to patients’ needs. In addition, lifestyle treatments, including smoking cessation and physical exercise, should be part of the medication counseling.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is predicted to become the fifth leading cause of disability and the third leading cause of death around the world by 2020. Though it is potentially treatable and preventable, evidence of brain structural alterations in COPD remains sparse and conflicting. We aim to investigate the effect of Liuweibuqi capsules on CD4+CD25+ Forkhead box protein 3+ (Foxp3+) regulatory T cells (Tregs), helper T cells (Th) and lung function in patients with stable COPD complicated with lung Qi deficiency. Methods COPD patients with lung Qi deficiency [458] were assigned into non-smoking COPD (NS-COPD), non-smoking control (NS-control), smoking COPD (S-COPD) and smoking control (S-control) groups, and healthy volunteers [245] into the non-smoking healthy (NSH) and smoking healthy (SH) groups. Levels of inflammatory cytokines were detected by Enzyme-linked immunoassay (ELISA). Contents of inflammatory cells, inflammatory marker, and CD4+CD25+Fox3+Tregs were measured by flow cytometry. FEV1/FVC (%) and FEV1 (%) were detected by pulmonary function test apparatus. Correlation between FEV1 (%) and Th1, Th2, Th17, Th1/Th2 or CD4+CD25+Fox3+Tregs was analyzed by Spearman rank correlation test. The related factors affecting treatment efficacy was assessed by logistic analysis. Results COPD patients and smoking people showed higher level of INF-γ, IL-4, IL-17, Th1, Th2, Th17 and Th1/Th2 but lower level of CD4+CD25+Fox3+Tregs. Liuweibuqi capsules could decrease level of inflammatory cells, cytokines, and markers (especially Th17 and IL-17), and increase level of CD4+CD25+Fox3+Tregs. FEV1 (%) negatively correlated with Th1, Th2, Th17 and Th1/Th2 but positively correlated with CD4+CD25+Fox3+Tregs, and smoking may strengthen their correlation, but Liuweibuqi capsules may weaker their correlation. Levels of inflammatory cytokines, cells, marker, CD4+CD25+Fox3+Tregs, FEV1/FVC (%), FEV1 (%), smoking and Liuweibuqi capsules are factors affecting efficacy. Conclusions Taken together, our data support the notion that smoking is an important factor to induce and aggravate COPD. Liuweibuqi capsules could stimulate proliferation of CD4+CD25+Fox3+Tregs and decrease Th17 expression to improve the lung function in stable COPD patients with lung Qi deficiency, and it had obvious efficacy for smoking COPD patients.

Abstract
The number of pharmacological treatments available for COPD has increased markedly in the last years, mostly corresponding to new agents, combinations and devices within know pharmacological classes. Hierarchizing these options is not straightforward since expected effects are limited by the intrinsically fixed character of the underlying lung damage. In addition, all options have not been directly compared face-to-face. Therefore, guidelines derive from some level of subjective interpretation of the available evidence. Determining which magnitude of change can be taken as clinically relevant is complex although crucial to define long-term strategies. Similarly, estimating not only the possible benefits but also the risks of treatments at the individual level is of major importance to guide choices. In the future biomarkers may be of help in that respect. They will hopefully emerge from progresses in systems biology and medicine. Before then, prescriptions should be restricted to the appropriate treatment indications, as established by high level studies and formalized by guidelines.

Abstract
Background This study aimed to investigate the effects of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) on airway changes in chronic obstructive pulmonary disease (COPD) rats exposed to air pollutant particles less than 2.5 micrometers in diameter (PM2.5), and to evaluate the mechanisms. Material/Methods Three groups were included in this study: a normal group, a COPD model group, and a COPD with 1,25(OH)2D3 treatment group. In each group, the rats were divided into four subgroups: control and different doses of PM2.5 (1.6, 8 and 40 mg/kg body weight). Apoptosis in lung tissue was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). The expression of c-Jun N-terminal kinase 1 (JNK1) and mucin 5AC (MUC5AC) were detected by real-time polymerase chain reaction (RT-PCR), Western blotting and immunofluorescence staining. Results Compared with corresponding subgroups in normal group, the apoptotic rates in COPD group were significantly increased. By contrast, 1,25(OH)2D3 treatment group significantly reduced COPD-induced apoptosis in lung tissue. Upon the dose increase of PM2.5, the apoptotic rate was also elevated in each group. Compared with the corresponding control in each group, PM2.5 increased apoptosis in a dose-dependent manner. Importantly, 1,25(OH)2D3 also prevented apoptosis in COPD rats exposed to PM2.5. Mechanically, the expression of MUC5AC and JNK1 in COPD group was significantly upregulated, compared with corresponding subgroups in the normal group. Treatment with 1,25(OH)2D3 reduced expression of MUC5AC and JNK1 in COPD rats. It was found that the expression of MUC5AC and JNK1 was elevated with the dose increase of PM2.5 in each group. Consistently, 1,25(OH)2D3 also reduced the expression of MUC5AC and JNK1 in COPD rats exposed to PM2.5. Conclusions 1,25(OH)2D3 prevented lung injury in COPD rats with or without PM2.5 exposure. Our results suggest that 1,25(OH)2D3 is useful to mitigate the injury caused by COPD.

Chronic obstructive pulmonary disease guidelines in Europe: a look into the future. Respir Res 2018; 19:11.

Abstract
Clinical practice guidelines are ubiquitous and are developed to provide recommendations for the management of many diseases, including chronic obstructive pulmonary disease. The development of these guidelines is burdensome, demanding a significant investment of time and money. In Europe, the majority of countries develop their own national guidelines, despite the potential for overlap or duplication of effort. A concerted effort and consolidation of resources between countries may alleviate the resource-intensity of maintaining individual national guidelines. Despite significant resource investment into the development and maintenance of clinical practice guidelines, their implementation is suboptimal. Effective strategies of guideline dissemination must be given more consideration, to ensure adequate implementation and improved patient care management in the future.

Abstract
INTRODUCTION The overlap between asthma and chronic obstructive pulmonary disease (COPD) (ACO) has been discussed for many years but clinical recommendations for this entity have been diverse. This study is intended to reach a consensus on diagnosis, treatment and patient orientation for ACO, within the Portuguese medical community. METHODS This study was conducted by a multidisciplinary panel of experts from three distinct medical specialties (Pulmonology, Family Medicine and Immunoallergology). This panel selected a total of 190 clinicians, based on their expertise in obstructive airway diseases, to participate in a Delphi structured survey with three rounds of questionnaires. These results were ultimately discussed, in a meeting with the panel of experts and some of the study participants, and consensus was reached in terms of classification criteria, treatment and orientation of ACO patients. RESULTS The majority of clinicians (87.2%) considered relevant the definition of an overlap entity between asthma and COPD. A consensus was achieved on the diagnosis of ACO - presence of simultaneous clinical characteristics of asthma and COPD together with a fixed airflow obstruction (FEV1/FVC<0.7) associated with 2 major criteria (previous history of asthma; presence of a previous history of smoking exposure and/or exposure to biomass combustion; positive bronchodilation test (increase in FEV1 of at least 200mL and 12%) on more than 1 occasion) plus 1 minor criteria (history of atopy; age ≥40 years; peripheral eosinophilia (>300eosinophils/μL or >5% of leukocytes); elevation of specific IgEs or positive skin tests for common allergens). A combination of inhaled corticosteroid (ICS) with long-acting beta2-agonist (LABA) or long-acting muscarinic antagonist (LAMA) was considered as first line pharmacological treatment. Triple therapy with ICS plus LABA and LAMA should be used in more severe or symptomatic cases. Non-pharmacological treatment, similar to what is recommended for asthma and COPD, was also considered highly important. A hospital referral of ACO patients should be made in symptomatic or severe cases or when there is a lack of diagnostic resources. CONCLUSIONS This study highlights the relevance of defining ACO, within the Portuguese medical community, and establishes diagnostic criteria that are important for future interventional studies. Recommendations on treatment and patient's orientation were also achieved.

Perceptions of Severe Asthma and Asthma-COPD Overlap Syndrome Among Specialists: A Questionnaire Survey. ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2018; 10:225-235.

Abstract
Purpose Severe asthma and asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) are difficult to control and are often associated with poor clinical outcomes. However, much is not understood regarding the diagnosis and treatment of severe asthma and ACOS. To evaluate the current perceptions of severe asthma and COPD among asthma and COPD specialists, we designed an e-mail and internet-based questionnaire survey. Methods Subjects were selected based on clinical specialty from among the members of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Academy of Tuberculosis and Respiratory Diseases. Of 432 subjects who received an e-mail invitation to the survey, 95 subjects, including 58 allergists and 37 pulmonologists, responded and submitted their answers online. Results The specialists estimated that the percentage of severe cases among total asthma patients in their practice was 13.9%±11.0%. Asthma aggravation by stepping down treatment was the most common subtype, followed by frequent exacerbation, uncontrolled asthma despite higher treatment steps, and serious exacerbation. ACOS was estimated to account for 20.7% of asthma, 38.0% of severe asthma, and 30.1% of COPD cases. A history of smoking, persistently low forced expiratory volume in 1 second (FEV1), and low FEV1 variation were most frequently classified as the major criteria for the diagnosis of ACOS among asthma patients. Among COPD patients, the highly selected major criteria for ACOS were high FEV1 variation, positive bronchodilator response, a personal history of allergies and positive airway hyperresponsiveness. Allergists and pulmonologists showed different assessments and opinions on asthma phenotyping, percentage, and diagnostic criteria for ACOS. Conclusions Specialists had diverse perceptions and clinical practices regarding severe asthma and ACOS patients. This heterogeneity must be considered in future studies and strategy development for severe asthma and ACOS.

Abstract
Maintenance pharmacological treatment for stable chronic obstructive pulmonary disease (COPD) is based on inhaled drugs, including long-acting muscarinic receptor antagonists (LAMA), long-acting β2-adrenoceptor agonists (LABA) and inhaled corticosteroids (ICS). Inhaled pharmacological treatment can improve patients' daily symptoms and reduce decline of pulmonary function and acute exacerbation rate. Treatment with all three inhaled drug classes is reserved for selected, more severe, patients with COPD when symptoms are not sufficiently controlled by dual LABA/LAMA therapy and exacerbations are frequent. This review focuses on the role of single-inhaler triple therapy with once-daily fluticasone furoate/umeclidinium/vilanterol fixed-dose combination, which is in phase III clinical development for maintenance treatment of severe-to-very severe COPD. In this review, we summarize evidence providing the rationale for its use in COPD and discuss the gaps to be filled in this pharmacotherapeutic area.

Abstract
AIMS To study the short- and long-term results of pulmonary rehabilitation (PR) given in the Helsinki University Heart and Lung Center and to understand the hospital resources used to treat severe COPD exacerbations in the city of Helsinki. MATERIALS AND METHODS Seventy-eight inactive patients with severe COPD were recruited for a PR course; three of them did not finish the course. The course took 6-8 weeks and included 11-16 supervised exercise sessions. Using electronic medical records, we studied all COPD patients with hospital admission in the city of Helsinki in 2014, including COPD diagnosis, criteria for exacerbation, and potential exclusion/inclusion criteria for PR. RESULTS Seventy-five of the patients finished the PR course and 92% of those patients showed clinically significant improvement. Their hospital days were reduced by 54% when compared to the year before. At 1 year after the course, 53% of the patients reported that they have continued with regular exercise training. In the city of Helsinki, 437 COPD patients were treated in a hospital due to exacerbation during 2014. On the basis of their electronic medical records, 57% of them would be suitable for PR. According to a rough estimate, 10%-20% hospital days could be saved annually if PR was available to all, assuming that the PR results would be as good as those shown here. CONCLUSIONS The study showed that in a real-world setting, PR is efficient when measured by saved hospital days in severe COPD. Half of the patients could be motivated to continue exercising on their own.

Abstract
PURPOSE OF REVIEW To illustrate the scant evidence and the shortcomings of the concept of 'asthma-COPD overlap syndrome' (ACOS) in terms of clinical utility. RECENT FINDINGS Asthma and chronic obstructive pulmonary disease (COPD) are considered as two distinct and heterogeneous diseases. For many years, physicians have been aware that asthma and COPD can coexist in some patients. Recently, the term ACOS has been applied when a person has clinical features of both asthma and COPD. However, the lack of an accurate diagnosis has led to inconsistent data regarding reported prevalence, prognosis and therapeutics. Even today, it has not been possible to establish a phenotypic characterization of ACOS, although it is part of the overall complexity and heterogeneity of COPDs. No high quality data exist on which to base treatment recommendations for ACOS. Consequently, in clinical practice, treatment is extrapolated from the available evidence on asthma and COPD. SUMMARY The current concept of ACOS seems clinically irrelevant because it has no influence on the prognosis and treatment of these patients. The authors concluded that the term ACOS should be avoided in the case of patients with features of both asthma and COPD.

Abstract
OBJECTIVES Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. METHODS A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. RESULTS From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). CONCLUSION Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

Abstract
Inhaled corticosteroids (ICSs) are the cornerstone of the treatment of asthma, but their role in COPD is limited. Several guidelines recommend their use in patients with severe airflow limitation, frequent exacerbations and asthma-COPD overlap (ACO), while the previous GOLD document recommended ICS for patients with high risk of exacerbations and a high level of symptoms (group D). Following the changes in the GOLD document 2017 update, in which impaired lung function is no longer considered as a determinant of exacerbation risk, a high number of COPD patients can now be labeled as group B (low risk of exacerbations and high level of symptoms) instead of D, and hence, no longer fulfill the indication for ICS. Since long-term therapy with ICS can entail secondary effects, the withdrawal of this treatment should be considered in this group of patients. In this article, we summarize the evidence for discontinuation of ICS in this subgroup of patients and provide suggestions for clinicians on the appropriate use on ICS in patients moving from D to B.
