Abstract
Background The use of inhaled corticosteroids (ICS) in combination with bronchodilators in patients with COPD has been shown to decrease the rate of disease exacerbations and to improve the lung function and patients’ quality of life. However, their use has also been associated with an increased risk of pneumonia. Materials and methods We have reviewed existing clinical evidence on the risks and benefits of ICS in COPD, including large randomized clinical trials, meta-analyses, and clinical reviews. Results A large body of evidence supports the clinical benefits of ICS in patients with COPD in terms of exacerbations, symptoms, lung function, and quality of life. The incidence of adverse events related to ICS, including pneumonia, varies strongly among the studies and seems to be dose dependent, with recent well-designed, large studies on low-dose ICS reporting similar safety profiles in ICS and non-ICS groups. Conclusion The benefits of ICS in COPD continue to outweigh the risks, especially when lower ICS doses are employed. Given that the data on ICS withdrawal in COPD are scarce and conflicting, we argue that using reduced doses of ICS could be an optimal strategy to manage patients with COPD.

Abstract
Background To support patients with COPD in their self-management of symptom worsening, we developed Adaptive Computerized COPD Exacerbation Self-management Support (ACCESS), an innovative software application that provides automated treatment advice without the interference of a health care professional. Exacerbation detection is based on 12 symptom-related yes-or-no questions and the measurement of peripheral capillary oxygen saturation (SpO2), forced expiratory volume in one second (FEV1), and body temperature. Automated treatment advice is based on a decision model built by clinical expert panel opinion and Bayesian network modeling. The current paper describes the validity of ACCESS. Methods We performed secondary analyses on data from a 3-month prospective observational study in which patients with COPD registered respiratory symptoms daily on diary cards and measured SpO2, FEV1, and body temperature. We examined the validity of the most important treatment advice of ACCESS, ie, to contact the health care professional, against symptom- and event-based exacerbations. Results Fifty-four patients completed 2,928 diary cards. One or more of the different pieces of ACCESS advice were provided in 71.7% of all cases. We identified 115 symptom-based exacerbations. Cross-tabulation showed a sensitivity of 97.4% (95% CI 92.0-99.3), specificity of 65.6% (95% CI 63.5-67.6), and positive and negative predictive value of 13.4% (95% CI 11.2-15.9) and 99.8% (95% CI 99.3-99.9), respectively, for ACCESS' advice to contact a health care professional in case of an exacerbation. Conclusion In many cases (71.7%), ACCESS gave at least one self-management advice to lower symptom burden, showing that ACCES provides self-management support for both day-to-day symptom variations and exacerbations. High sensitivity shows that if there is an exacerbation, ACCESS will advise patients to contact a health care professional. The high negative predictive value leads us to conclude that when ACCES does not provide the advice to contact a health care professional, the risk of an exacerbation is very low. Thus, ACCESS can safely be used in patients with COPD to support self-management in case of an exacerbation.

Abstract
The major determinant of the decline in lung function, quality of life, and the increased mortality risk in patients with COPD is represented by severe acute exacerbations of the disease, that is, those requiring patients’ hospitalization, constituting a substantial social and health care burden in terms of morbidity and medical resource utilization. Different long-term therapeutic strategies have been proposed so far in order to prevent and/or reduce the clinical and social impact of these events, the majority of which were extrapolated from trials initially focused on the effect of long-acting muscarinic antagonist and subsequently on the efficacy of long-acting β2-agonists in combination or not with inhaled corticosteroids. The option to employ all three classes of molecules combined, despite the limited amount of evidence in our possession, represents a choice currently proposed by international guidelines; however, current recommendations are often based mainly on observational studies or on the results of secondary outcomes in randomized controlled trials. The present narrative review evaluates the available trials that investigated the efficacy of inhaled therapy to prevent COPD exacerbations and especially severe ones, with a particular focus on beclomethasone dipropionate/formoterol/glycopyrronium bromide fixed dose combination, which is the first treatment that comprises all the three drug classes, specifically tested for the prevention of moderate and severe COPD exacerbations.

Abstract
Background Patients with COPD often experience severe exacerbations involving hospitalization, which accelerate lung function decline and reduce quality of life. This study aimed to develop and validate a predictive model to identify patients at risk of developing severe COPD exacerbations using administrative claims data, to facilitate appropriate disease management programs. Methods A predictive model was developed using a retrospective cohort of COPD patients aged 55–89 years identified between July 1, 2010 and June 30, 2013 using Humana’s claims data. The baseline period was 12 months postdiagnosis, and the prediction period covered months 12–24. Patients with and without severe exacerbations in the prediction period were compared to identify characteristics associated with severe COPD exacerbations. Models were developed using stepwise logistic regression, and a final model was chosen to optimize sensitivity, specificity, positive predictive value (PPV), and negative PV (NPV). Results Of 45,722 patients, 5,317 had severe exacerbations in the prediction period. Patients with severe exacerbations had significantly higher comorbidity burden, use of respiratory medications, and tobacco-cessation counseling compared to those without severe exacerbations in the baseline period. The predictive model included 29 variables that were significantly associated with severe exacerbations. The strongest predictors were prior severe exacerbations and higher Deyo–Charlson comorbidity score (OR 1.50 and 1.47, respectively). The best-performing predictive model had an area under the curve of 0.77. A receiver operating characteristic cutoff of 0.4 was chosen to optimize PPV, and the model had sensitivity of 17%, specificity of 98%, PPV of 48%, and NPV of 90%. Conclusion This study found that of every two patients identified by the predictive model to be at risk of severe exacerbation, one patient may have a severe exacerbation. Once at-risk patients are identified, appropriate maintenance medication, implementation of disease-management programs, and education may prevent future exacerbations.

Abstract
BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) impacts differently on patients at similar grades, suggesting that factors other than lung function may influence patients' experience of the disease. Recent studies have found associations between genetic variations and patient-reported outcomes (PROs). Identifying these associations might be fundamental to predict the disease progression and develop tailored interventions. This systematic review aimed to identify the genetic variations associated with PROs in COPD. METHODS AND FINDINGS Databases were searched until July 2017 (PROSPERO: CRD42016041639) and additional searches were conducted scanning the reference list of the articles. Two independent reviewers assessed the quality of studies using the Q-Genie checklist. This instrument is composed of 11 questions, each subdivided in 7 options from 1 poor-7 excellent. Thirteen studies reporting 5 PROs in association with genes were reviewed. Studies were rated between "good quality" (n = 8) and "moderate" (n = 5). The most reported PRO was frequency of exacerbations (n = 7/13), which was mainly associated with MBL2 gene variants. Other PRO's were health-related quality of life (HRQOL) (n = 4/13), depressive symptoms (n = 1/13), exacerbation severity (n = 1/13) and breathlessness, cough and sputum (n = 1/13), which were commonly associated with other genetic variants. CONCLUSIONS Although a limited number of PRO's have been related to genetic variations, findings suggest that there is a significant association between specific gene variants and the number/severity of exacerbations, depressive symptoms and HRQOL. Further research is needed to confirm these findings and assess the genetic influence on other dimensions of patients' lives, since it may enhance our understanding and management of COPD.

Abstract
There has been a recent surge in interest in the role of inhaled corticosteroids (ICS) in the treatment of COPD, especially regarding patients with high eosinophil counts. Evidence has shown that despite the increase in localised adverse effects and a small increase in non-fatal pneumonia events with ICS use, ICS still have an important role to play in reducing exacerbation rates and addressing the inflammation that is at the heart of the pathogenesis of COPD. Current international guidelines recommend the use of ICS only in patients with severe disease. This review examines the potential role of ICS in all COPD patients.

Abstract
COPD exacerbations are commonly quantified as rate per year. However, the total amount of time a patient suffers from exacerbations may be stronger related to his or her disease burden than just counting exacerbation episodes. In this study, we examined the relationship between exacerbation frequency and exacerbation-free time, and their associations with baseline characteristics and health-related quality of life. A total of 166 COPD patients reported symptom changes during 12 months. Symptom-defined exacerbation episodes were correlated to the number of exacerbation-free weeks per year. Analysis of covariance was used to examine the effects of baseline characteristics on annual exacerbation frequency and exacerbation-free weeks, Spearman’s rank correlations to examine associations between the two methods to express exacerbations and the Chronic Respiratory Questionnaire (CRQ). The correlation between exacerbation frequency and exacerbation-free weeks was −0.71 (p < 0.001). However, among frequent exacerbators (i.e., ≥3 exacerbations/year, n = 113) the correlation was weak (r = −0.25; p < 0.01). Smokers had less exacerbation-free weeks than non-smokers (β = −5.709, p < 0.05). More exacerbation-free weeks were related to better CRQ Total (r = 0.22, p < 0.05), Mastery (r = 0.22, p < 0.05), and Fatigue (r = 0.23, p < 0.05) scores, whereas no significant associations were found between exacerbation frequency and CRQ scores. In COPD patients with frequent exacerbations, there is substantial variation in exacerbation-free time. Exacerbation-free time may better reflect the burden of exacerbations in patients with COPD than exacerbation frequency does. Time spent exacerbation-free may provide a stronger indication of disease burden than exacerbation frequency for patients with chronic lung disease. Exacerbations in chronic obstructive pulmonary disease (COPD) are marked by a sudden decline in lung function, potential hospitalisation and a need to increase medication. Exacerbation frequency is used as a marker in COPD management, but this does not consider the duration of exacerbations or the impact this has on patients’ lives. Lonneke Boer at Radboud University Medical Center, the Netherlands, and co-workers questioned 166 patients every two weeks for a year about their experiences of exacerbation duration and frequency. There was substantial variation in exacerbation-free time between patients, with smokers most likely to suffer longer periods of poorer health. Exacerbation-free time was better correlated with health-related quality of life than exacerbation frequency.

Abstract
Severe exacerbations of COPD, ie, those leading to hospitalization, have profound clinical implications for patients and significant economic consequences for society. The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system. This review identified risk factors that contribute to the development of severe exacerbations, treatment options (bronchodilators, antibiotics, corticosteroids [CSs], oxygen therapy, and ventilator support) to manage severe exacerbations, and strategies to prevent readmission to hospital. Risk factors that are amenable to change have been highlighted. A number of bronchodilators have demonstrated successful reduction in risk of severe exacerbations, including long-acting muscarinic antagonist or long-acting β2-agonist mono- or combination therapies, in addition to vaccination, mucolytic and antibiotic therapy, and nonpharmacological interventions, such as pulmonary rehabilitation. Recognition of the importance of severe exacerbations is an essential step in improving outcomes for patients with COPD. Evidence-based approaches to prevent and manage severe exacerbations should be implemented as part of targeted strategies for disease management.

Abstract
Acute exacerbations are a leading cause of worsening COPD in terms of lung function decline, quality of life, and survival. They also have a relevant economic burden on the health care system. Determining the risk factors for acute exacerbation and early relapse could be a crucial element for a better management of COPD patients. This review analyzes the current knowledge and underlines the main risk factors for recurrent acute exacerbations. Comprehensive evaluation of COPD patients during stable phase and exacerbation could contribute to prevent treatment failure and relapses.

Abstract
RATIONALE Acute exacerbations of chronic obstructive pulmonary disease (COPD) increase the risk of death and drive healthcare costs, but whether they accelerate loss of lung function remains controversial. Whether exacerbations in subjects with mild COPD or similar acute respiratory events in smokers without airflow obstruction affect lung function decline is unknown. OBJECTIVES To determine the association between acute exacerbations of COPD (and acute respiratory events in smokers without COPD) and the change in lung function over 5 years of follow-up. METHODS We examined data on the first 2,000 subjects who returned for a second COPDGene visit 5 years after enrollment. Baseline data included demographics, smoking history, and computed tomography emphysema. We defined exacerbations (and acute respiratory events in those without established COPD) as acute respiratory symptoms requiring either antibiotics or systemic steroids, and severe events by the need for hospitalization. Throughout the 5-year follow-up period, we collected self-reported acute respiratory event data at 6-month intervals. We used linear mixed models to fit FEV1 decline based on reported exacerbations or acute respiratory events. MEASUREMENTS AND MAIN RESULTS In subjects with COPD, exacerbations were associated with excess FEV1 decline, with the greatest effect in Global Initiative for Chronic Obstructive Lung Disease stage 1, where each exacerbation was associated with an additional 23 ml/yr decline (95% confidence interval, 2-44; P = 0.03), and each severe exacerbation with an additional 87 ml/yr decline (95% confidence interval, 23-151; P = 0.008); statistically significant but smaller effects were observed in Global Initiative for Chronic Obstructive Lung Disease stage 2 and 3 subjects. In subjects without airflow obstruction, acute respiratory events were not associated with additional FEV1 decline. CONCLUSIONS Exacerbations are associated with accelerated lung function loss in subjects with established COPD, particularly those with mild disease. Trials are needed to test existing and novel therapies in subjects with early/mild COPD to potentially reduce the risk of progressing to more advanced lung disease. Clinical trial registered with www.clinicaltrials.gov (NCT 00608764).

Abstract
Chronic obstructive pulmonary disease (COPD) is a common condition encountered in primary care settings. COPD remains the third leading cause of death in the United States and carries a significant burden to both patients and the healthcare system. COPD is a chronic, progressive, irreversible lung disease associated with high morbidity and mortality. Proper assessment and diagnosis requires spirometry which is currently underutilized in primary care. Management is focused on adequate symptom control, improving quality of breathing and quality of life, and preventing exacerbations and hospitalizations. However, many patients are not receiving long-acting bronchodilator maintenance therapy as recommended in current clinical guidelines. Even when patients receive appropriate therapy, real-world issues such as a patient's health literacy, physical and cognitive limitations, and therapy nonadherence limit the effectiveness of prescribed inhaled medications. Primary care providers are well situated to ensure that prescribed therapies and long-term management goals are matched to the individual needs of patients with COPD.

Abstract
The treatment of COPD has become increasingly effective. Measures that range from behavioral changes, reduction in exposure to risk factors, education about the disease and its course, rehabilitation, oxygen therapy, management of comorbidities, and surgical and pharmacological treatments to end-of-life care allow health professionals to provide a personalized and effective therapy. The pharmacological treatment of COPD is one of the cornerstones of COPD management, and there have been many advances in this area in recent years. Given the greater availability of drugs and therapeutic combinations, it has become increasingly challenging to know the indications for, limitations of, and potential risks and benefits of each treatment modality. In order to critically evaluate recent evidence and systematize the major questions regarding the pharmacological treatment of COPD, 24 specialists from all over Brazil gathered to develop the present recommendations. A visual guide was developed for the classification and treatment of COPD, both of which were adapted to fit the situation in Brazil. Ten questions were selected on the basis of their relevance in clinical practice. They address the classification, definitions, treatment, and evidence available for each drug or drug combination. Each question was answered by two specialists, and then the answers were consolidated in two phases: review and consensus by all participants. The questions answered are practical questions and help select from among the many options the best treatment for each patient and his/her peculiarities.

Abstract
Chronic obstructive pulmonary disease (COPD) phenotyping can help define clusters of patients with common characteristics that relate to clinically meaningful outcomes. In this review, we describe 7 clinically meaningful COPD phenotypes that can be identified by primary care physicians as well as specialists and that have specific management and prognostic implications: (1) asthma-COPD overlap phenotype, (2) frequent exacerbator phenotype, (3) upper lobe-predominant emphysema phenotype, (4) rapid decliner phenotype, (5) comorbid COPD phenotype, (6) physical frailty phenotype, and (7) emotional frailty phenotype.

Stability of the frequent COPD exacerbator in the general population: A Danish nationwide register-based study. NPJ Prim Care Respir Med 2017; 27:25.

Abstract
Exacerbation frequency is central in treatment strategies for chronic obstructive pulmonary disease. However, whether chronic obstructive pulmonary disease patients from the general population with frequent exacerbations continue to have frequent exacerbations over an extended period of time is currently unknown. In this study, we aimed to investigate the stability of the frequent exacerbator in a population-based setting. To this end, we conducted a nationwide register-based descriptive study with a 10-year follow-up period of chronic obstructive pulmonary disease patients with at least one medically treated exacerbation in 2003. Each subsequent year, we divided the population into frequent, infrequent and non-exacerbators and quantified the flow between categories. Further, we estimated the percentage of frequent exacerbators at baseline who stayed in this category each year during a 5-year follow-up. We identified 19,752 patients with chronic obstructive pulmonary disease and an exacerbation in 2003. Thirty percent were frequent exacerbators. Overall, the majority of exacerbators in 2003 were non-exacerbators in the following years (60% in 2004 increasing to 68% in 2012). Approximately half of frequent exacerbators in one year experienced a decrease in exacerbation frequency and had either zero or one exacerbation in the subsequent year. This pattern was stable throughout follow-up. During a 5-year follow-up period, a substantial proportion (42%) of frequent exacerbators in 2003 had no additional years as frequent exacerbators, while the minority (6%) remained in this category each year. In conclusion, the rate of exacerbations shows considerable variation over time among chronic obstructive pulmonary disease patients in the general population. This might hold implications for chronic obstructive pulmonary disease treatment guidelines and their practical application. Patients with chronic obstructive pulmonary disease (COPD) who suffer from frequent exacerbations do not necessarily persist with such severity over time. Exacerbations in COPD are defined by worsening respiratory symptoms that result in changes to treatment, hospitalization and, at worst, death. However, clarity is needed on whether frequent exacerbations is a stable feature of some patients’ disease. Mette Reilev at the University of Southern Denmark and co-workers followed, over 10 years, 19,752 COPD patients living in Denmark who suffered at least one exacerbation in 2003. By 2004, 60% of patients were classed as infrequent or non-exacerbators, rising to 68% by 2012. Very few patients remained “frequent exacerbators”, suggesting the rate of exacerbations changes considerably over time. This could hold implications for COPD treatment and challenge assumptions made about disease progression.

Abstract
Purpose COPD is characterized by an accelerated and progressive decline in forced expiratory volume in 1 second (FEV1) and lung hyperinflation. Although lung hyperinflation is the hallmark of COPD, data on the longitudinal changes in lung hyperinflation and any association with the decline in FEV1 are lacking. The aim of this study was to evaluate the longitudinal changes in lung hyperinflation and to investigate its relationship with FEV1 decline. Patients and methods We conducted a prospective cohort study and studied 176 COPD patients with annual lung volume measurements over a period of 5 years or more. We used a random coefficient model to calculate the annual changes in lung volumes and to evaluate the factors associated with changes in lung hyperinflation. Additionally, the relationship between the change in lung hyperinflation and FEV1 was assessed. Results Residual volume (RV), inspiratory capacity (IC), and total lung capacity (TLC) declined at a mean rate of 39.5, 49.6, and 63.8 mL/year, respectively. While IC/TLC declined at 0.70%/year, RV/TLC also declined at 0.35%/year. Changes in both IC/TLC and RV/TLC varied significantly. Frequent exacerbations led to an increase in RV/TLC and faster decline in IC/TLC over time. RV/TLC declined in 59.7% and increased in 40.3% of the patients. A significant negative correlation was found between the rates of change in FEV1 and RV/TLC, and the rate of decline in FEV1 was greater in patients with an increase in RV/TLC than in those with a decline in RV/TLC (54.2 vs 10.7 mL/year, P<0.001). Conclusion The rate of change in lung hyperinflation varied greatly among COPD patients. Progression of hyperinflation was associated with frequent exacerbations and a faster decline in FEV1.

Abstract
BACKGROUND Hospitalisations for chronic obstructive pulmonary disease (COPD) exacerbation affect patient outcomes and healthcare costs. The long-term impact of an integrated COPD disease-management approach on hospitalisation remains controversial. AIM The aim of this study was to evaluate whether a multidisciplinary community service reduces respiratory hospitalisations for COPD patients. METHODS A total of 346 patients was followed for a mean duration of 27.3 months. The number of admissions, total bed days for respiratory (COPD exacerbation or pneumonia) or general medical causes and length of stay (LOS) per respiratory admission was compared before and after referral with the service. A secondary multivariate analysis examined which clinical parameters best predict benefit from such service. RESULTS The total respiratory admission and hospital bed days after referral were reduced by 31% (288 vs 417, P < 0.001) and 40.4% (1637 vs 2746, P < 0.0001) respectively, compared with the equivalent duration prior. The average LOS for each respiratory admission was also significantly reduced after referral (6.61 vs 5.70, P = 0.02). Overall, 55% patients experienced a reduction in admission frequency and hospital days. The impact on admission frequency and hospital days was the greatest in those with an at least moderate disease (GOLD ≥2, odds ratio (OR): 3.2, 95% confidence interval (CI): 1.2, 8.9; P = 0.019) and those who completed pulmonary rehabilitation (PR) (OR: 1.7, 95% CI: 1.1, 2.8; P = 0.04). In contrast, general medical admissions increased, one-third attributable to a cardiovascular cause both before and after referral. CONCLUSIONS The implementation of COPD multidisciplinary community service was associated with reduced respiratory hospitalisations in the long term. Patients with moderate or severe disease and who are able to complete PR are much more likely to benefit.

Abstract
BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are a major driver of decline in health status and impose high costs on healthcare systems. Action plans offer a form of self-management that can be delivered in the outpatient setting to help individuals recognise and initiate early treatment for exacerbations, thereby reducing their impact. OBJECTIVES To compare effects of an action plan for COPD exacerbations provided with a single short patient education component and without a comprehensive self-management programme versus usual care. Primary outcomes were healthcare utilisation, mortality and medication use. Secondary outcomes were health-related quality of life, psychological morbidity, lung function and cost-effectiveness. SEARCH METHODS We searched the Cochrane Airways Group Specialised Register along with CENTRAL, MEDLINE, Embase and clinical trials registers. Searches are current to November 2015. We handsearched bibliographic lists and contacted study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCT) and quasi-RCTs comparing use of an action plan versus usual care for patients with a clinical diagnosis of COPD. We permitted inclusion of a single short education component that would allow individualisation of action plans according to management needs and symptoms of people with COPD, as well as ongoing support directed at use of the action plan. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. For meta-analyses, we subgrouped studies via phone call follow-up directed at facilitating use of the action plan. MAIN RESULTS This updated review includes two additional studies (and 976 additional participants), for a total of seven parallel-group RCTs and 1550 participants, 66% of whom were male. Participants' mean age was 68 years and was similar among studies. Airflow obstruction was moderately severe in three studies and severe in four studies; mean post bronchodilator forced expiratory volume in one second (FEV1) was 54% predicted, and 27% of participants were current smokers. Four studies prepared individualised action plans, one study an oral plan and two studies standard written action plans. All studies provided short educational input on COPD, and two studies supplied ongoing support for action plan use. Follow-up was 12 months in four studies and six months in three studies.When compared with usual care, an action plan with phone call follow-up significantly reduced the combined rate of hospitalisations and emergency department (ED) visits for COPD over 12 months in one study with 743 participants (rate ratio (RR) 0.59, 95% confidence interval (CI) 0.44 to 0.79; high-quality evidence), but the rate of hospitalisations alone in this study failed to achieve statistical significance (RR 0.69, 95% CI 0.47 to 1.01; moderate-quality evidence). Over 12 months, action plans significantly decreased the likelihood of hospital admission (odds ratio (OR) 0.69, 95% CI 0.49 to 0.97; n = 897; two RCTs; moderate-quality evidence; number needed to treat for an additional beneficial outcome (NNTB) 19 (11 to 201)) and the likelihood of an ED visit (OR 0.55, 95% CI 0.38 to 0.78; n = 897; two RCTs; moderate-quality evidence; NNTB over 12 months 12 (9 to 26)) compared with usual care.Results showed no significant difference in all-cause mortality during 12 months (OR 0.88, 95% CI 0.59 to 1.31; n = 1134; four RCTs; moderate-quality evidence due to wide confidence interval). Over 12 months, use of oral corticosteroids was increased with action plans compared with usual care (mean difference (MD) 0.74 courses, 95% CI 0.12 to 1.35; n = 200; two RCTs; moderate-quality evidence), and the cumulative prednisolone dose was significantly higher (MD 779.0 mg, 95% CI 533.2 to 10248; n = 743; one RCT; high-quality evidence). Use of antibiotics was greater in the intervention group than in the usual care group (subgrouped by phone call follow-up) over 12 months (MD 2.3 courses, 95% CI 1.8 to 2.7; n = 943; three RCTs; moderate-quality evidence).Subgroup analysis by ongoing support for action plan use was limited; review authors noted no subgroup differences in the likelihood of hospital admission or ED visits or all-cause mortality over 12 months. Antibiotic use over 12 months showed a significant difference between subgroups in studies without and with ongoing support.Overall quality of life score on St George's Respiratory Questionnaire (SGRQ) showed a small improvement with action plans compared with usual care over 12 months (MD -2.8, 95% CI -0.8 to -4.8; n = 1009; three RCTs; moderate-quality evidence). Low-quality evidence showed no benefit for psychological morbidity as measured with the Hospital Anxiety and Depression Scale (HADS). AUTHORS' CONCLUSIONS Use of COPD exacerbation action plans with a single short educational component along with ongoing support directed at use of the action plan, but without a comprehensive self-management programme, reduces in-hospital healthcare utilisation and increases treatment of COPD exacerbations with corticosteroids and antibiotics. Use of COPD action plans in this context is unlikely to increase or decrease mortality. Whether additional benefit is derived from periodic ongoing support directed at use of an action plan cannot be determined from the results of this review.

Abstract
Determining which patients with COPD may benefit from a nebulized long-acting beta2-agonist (LABA) is a challenge in current practice. In the absence of strong clinical guidelines addressing this issue, an expert panel convened to develop guiding principles for the use of nebulized LABA therapy in patients with COPD. This article summarizes these guiding principles and other practical issues discussed during a roundtable meeting.

Abstract
BACKGROUND Management of chronic obstructive pulmonary disease (COPD) commonly involves long-acting bronchodilators including beta-agonists (LABA) and muscarinic antagonists (LAMA). In individuals with persistent symptoms or frequent exacerbations, inhaled corticosteroids (ICS) are also used. LABA and LAMA bronchodilators are now available in single combination inhalers. However, the benefits and risks of adding ICS to combination LABA/LAMA inhalers remains unclear. OBJECTIVES To assess the effect of adding an inhaled corticosteroid (ICS) to combination long-acting beta₂-agonist (LABA)/long-acting muscarinic antagonist (LAMA) inhalers for the treatment of stable COPD. SEARCH METHODS We carried out searches using the Cochrane Airways Group Specialised Register of Trials (searched 20 September 2016), Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12) in the Cochrane Library (searched 15 December 2015) and MEDLINE (searched 15 December 2015). We also searched ClinicalTrials.gov, World Health Organisation (WHO) trials portal and pharmaceutical company clinical trials' databases up to 7 Janurary 2016. SELECTION CRITERIA We included parallel-group, randomised controlled trials (RCTs) of three weeks' duration or longer which compared treatment of stable COPD with ICS in addition to combination LABA/LAMA inhalers against combination LABA/LAMA inhalers alone. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We identified a total of 586 records in our search. Following removal of duplicates, 386 abstracts were assessed for inclusion. Six studies were identified as potentially relevant; however, all failed to meet the inclusion criteria on full-text assessment or after contacting the corresponding author to clarify study characteristics. AUTHORS' CONCLUSIONS There are currently no studies published assessing the effect of ICS in addition to combination LABA/LAMA inhalers for the treatment of stable COPD. As combination LABA/LAMA inhalers are now widely available, there is a need for well-designed RCTs to investigate whether ICS provides any added therapeutic benefit.

Abstract
The new A-B-C-D Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification of severity of chronic obstructive pulmonary disease (COPD) is based on combined symptoms and exacerbation risk assessment. The assumed equivalence between dyspnoea modified Medical Research Council (mMRC) grade ≥2 and COPD Assessment Test (CAT) score ≥ 10 to identify more symptoms has been questioned. Whether the exacerbation risk assessment criteria, old GOLD spirometry staging and frequency of exacerbations, are equivalent has not been examined. We evaluated the extent of agreement between these alternative criteria and whether it improved by redefining the equivalence between mMRC grade and CAT score. CAT scores, mMRC grades of dyspnoea, frequency of exacerbations and spirometry stages were computed in 400 patients with COPD. Receiver operating characteristic curve was analysed to determine the best CAT score to identify more symptoms. CAT scores across mMRC grades and the frequency of exacerbations across spirometry stages showed substantial overlaps. The symptoms criteria gave discordant classification in 88 (22%) patients (kappa 0.62) and the exacerbation risk assessment criteria in 181 (45%) patients (kappa 0.12). A CAT score of ≥10 had 82% sensitivity but 24% specificity to identify mMRC grade ≥ 2, while a score of 17 had 98% specificity but a low sensitivity of 52% and did not improve the agreement. We conclude that symptoms and exacerbation risk assessment criteria of the new GOLD classification yield discordant group categorisations. Lack of any satisfactory equivalence between CAT score and mMRC grades implies that the former cannot be used alone. Using the higher of mMRC ≥ 2 and CAT score ≥ 17 to identify more symptoms would avoid discordant categorisation.

Abstract
Chronic obstructive pulmonary disease (COPD) hospitalizations and readmissions adversely impact the health and quality of life of COPD patients. Under the Hospital Readmissions Reduction Program, the Centers for Medicare & Medicaid Services reduce payments to those hospitals exceeding expected rates of COPD readmissions within 30 days of hospital discharge. It was within this climate that the COPD Foundation held its 2nd COPD Readmissions Summit in March 2015. Experts in attendance: (1) categorized challenges to optimal COPD care, ( 2) analyzed the state of care delivery and readmissions reduction strategies and (3) identified the best available evidence-based approaches to improving care delivery across the continuum, including early diagnosis via spirometry, ongoing device, oxygen and medication reconciliation, treatment that addresses comorbidities and preventive care, robust patient education, prompt post-acute follow up, home health services and pulmonary rehabilitation. Results of this collaborative event formed the basis for PRAXIS, the COPD Foundation's initiative to improve COPD care across the health continuum and to reduce readmissions.

Abstract
Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66). Maintenance therapy (regular long-acting muscarinic antagonists, long-acting beta-2 agonists, inhaled corticosteroids, or theophylline) also increased the risk of AECOPD with both exacerbation definitions (incidence rate ratios 1.65 and 1.73, respectively). The risk of AECOPD was 59%–78% higher in the hospital sample than in the population sample. Conclusion If externally valid conclusions are to be made regarding incidence and predictors of AECOPD, studies should be based on general population samples or adjustments should be made on account of a likely higher incidence in other samples. Likewise, the effect of different AECOPD definitions should be taken into consideration.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the top five major causes of morbidity and mortality worldwide. Despite worldwide health care efforts, costs, and medical research, COPD figures demonstrate a continuously increasing tendency in mortality. This is contrary to other top causes of death, such as neoplasm, accidents, and cardiovascular disease. A major factor affecting COPD-related mortality is the acute exacerbation of COPD (AECOPD). Exacerbations and comorbidities contribute to the overall severity in individual patients. Despite the underestimation by the physicians and the patients themselves, AECOPD is a really devastating event during the course of the disease, similar to acute myocardial infarction in patients suffering from coronary heart disease. In this review, we focus on the evidence that supports the claim that AECOPD is the “stroke of the lungs”. AECOPD can be viewed as: a Semicolon or disease’s full-stop period, Triggering a catastrophic cascade, usually a Relapsing and Overwhelming event, acting as a Killer, needing Emergent treatment.

Abstract
Background Patients with COPD might not report mild exacerbation. The frequency, risk factors, and impact of mild exacerbation on COPD status are unknown. Objectives The present study was performed to compare features between mild exacerbation and moderate or severe exacerbation in Japanese patients with COPD. Patients and methods An observational COPD cohort was designed at Keio University and affiliated hospitals to prospectively investigate the management of COPD comorbidities. This study analyzes data only from patients with COPD who had completed annual examinations and questionnaires over a period of 2 years (n=311). Results Among 59 patients with mild exacerbations during the first year, 32.2% also experienced only mild exacerbations in the second year. Among 60 patients with moderate or severe exacerbations during the first year, 40% also had the same severity of exacerbation during the second year. Findings of the COPD assessment test and the symptom component of the St George’s Respiratory Questionnaire at steady state were worse in patients with mild exacerbations than in those who were exacerbation free during the 2-year study period, although the severity of the ratio of predicted forced expiratory volume in 1 second did not differ between them. Severe airflow limitation (the ratio of predicted forced expiratory volume in 1 second <50%) and experience of mild exacerbations independently advanced the likelihood of an elevated COPD assessment test score to ≥2 per year. Conclusion The severity of COPD exacerbation seemed to be temporally stable over 2 years, and even mild exacerbations adversely impacted the health-related quality of life of patients with COPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is often associated with recurrent hospitalizations. This study aimed to identify factors related to COPD rehospitalization. METHODS A national US claims database was used to identify patients, aged ≥40 years, hospitalized for COPD. Their first COPD-related hospital admission date in 2009 was set as the index date, with post-discharge COPD-related rehospitalization assessed for 180 days post-index date. Data were analyzed for: 1) all eligible patients in whom early COPD-related rehospitalization was evaluated (1-30 days post discharge; all-patient cohort) and 2) a patient subset not rehospitalized early in whom late COPD-related rehospitalization was evaluated (>30 days post discharge to 180 days post-index date; late cohort). Logistic regressions controlling for age and sex assessed potential COPD-related rehospitalization predictors. Variables from the 360-day pre-index period and index hospitalization were evaluated for each cohort, and 30-day post-discharge variables evaluated for the late cohort. RESULTS Of 3612 patients with an index hospitalization, 4.8 % (174) had an early COPD-related rehospitalization, and of the remaining 3438 patients, 13.7 % (471) had a late COPD-related rehospitalization. Several pre-index variables were predictive of early COPD-related rehospitalization including: pneumonia; comorbidities; COPD-related drug therapies; and prior hospitalizations. In patients not rehospitalized early, the strongest predictor of late COPD-related rehospitalization was pre-index COPD-related hospitalization (OR = 3.64 [P < 0.001]). The strongest index hospitalization factors predictive of late COPD-related rehospitalization were use of steroids (any route: OR = 1.62 [P = 0.007]) and nebulizers (OR = 1.65 [P = 0.007]); neither predicted early COPD-related rehospitalization. Generally, factors predicting COPD-related rehospitalization were similar in both cohorts. CONCLUSIONS Several pre-index variables were associated with COPD-related rehospitalization. A strong predictor of COPD-related rehospitalization was prior hospitalization during the pre-index period, particularly with a primary COPD diagnosis, whilst other predictive factors related to increased COPD severity; these may be useful indicators for COPD-related rehospitalization risk assessment. Some factors, e.g., recurrent pneumonia and exacerbations, may be modifiable.

Abstract
PURPOSE We investigated the association between cognitive impairment and chronic obstructive pulmonary disease (COPD), taking into account demographic and clinical variables evaluated during routine practice. PATIENTS AND METHODS We performed a post hoc analysis of a cross-sectional study that included subjects with stable COPD. Sociodemographic and clinical information was recorded using the Body mass index, airflow Obstruction, Dyspnea and Exacerbations index and the Charlson comorbidity index. Cognitive performance was studied by the mini-mental state examination, with a score less than 27 indicating clinical impairment. Depressive symptoms, physical activity, and quality of life (EuroQoL-5 dimensions and COPD Assessment Test) were also evaluated. RESULTS The analysis included 940 subjects. The prevalence of cognitive impairment was 39.4%. Multivariate logistic regression models revealed that cognitive impairment was associated with educational level (odds ratio [OR] =0.096, 95% confidence interval [CI] =0.011-0.447) and poorer quality of life measured by the EuroQoL-5 dimensions social tariff (OR =0.967, 95% CI =0.950-0.983). When questionnaires were not included in the analysis, cognitive impairment was associated with educational level (OR =0.063, 95% CI =0.010-0.934), number of exacerbations (OR =11.070, 95% CI =1.450-84.534), Body mass index, airflow Obstruction, Dyspnea and Exacerbations index score (OR =1.261, 95% CI =1.049-1.515), and the Charlson comorbidity index (OR =1.412, 95% CI =1.118-1.783). CONCLUSION Cognitive impairment is common in COPD and is associated with low educational level, higher disease severity, and increased comorbidity. This could have therapeutic implications for this population.

Abstract
This observational study assessed the relationship between nighttime, early-morning and daytime chronic obstructive pulmonary disease (COPD) symptoms and exacerbations and healthcare resource use. COPD symptoms were assessed at baseline in patients with stable COPD using a standardised questionnaire during routine clinical visits. Information was recorded on exacerbations and healthcare resource use during the year before baseline and during a 6-month follow-up period. The main objective of the analysis was to determine the predictive nature of current symptoms for future exacerbations and healthcare resource use. 727 patients were eligible (65.8% male, mean age: 67.2 years, % predicted forced expiratory volume in 1 second: 52.8%); 698 patients (96.0%) provided information after 6 months. Symptoms in any part of the day were associated with a prior history of exacerbations (all p < 0.05) and nighttime and early-morning symptoms were associated with the frequency of primary care visits in the year before baseline (both p < 0.01). During follow-up, patients with baseline symptoms during any part of the 24-hour day had more exacerbations than patients with no symptoms in each period (all p < 0.05); there was also an association between 24-hour symptoms and the frequency of primary care visits (all p ≤ 0.01). Although there was a significant association between early-morning and daytime symptoms and exacerbations during follow-up (both p < 0.01), significance was not maintained when adjusted for potential confounders. Prior exacerbations were most strongly associated with future risk of exacerbation. The results suggest 24-hour COPD symptoms do not independently predict future exacerbation risk.

Abstract
OBJECTIVE Living in an area with a high density of livestock farms has been associated with adverse respiratory health effects in some studies. As patients with COPD and asthma already have a compromised respiratory function and chronic airway inflammation, they are expected to be at increased risk for adverse respiratory health effects. The objective of this study was to assess the association between livestock exposure and exacerbations in COPD and asthma. METHODS 899 COPD and 2546 asthma patients from 15 general practices in a rural area with a high livestock density and 933 COPD and 2310 asthma patients from 15 practices in a control area in the Netherlands were included. Occurrence of exacerbations was based on the pharmaceutical treatment of exacerbations in COPD and asthma patients using 2006-2012 prescription data of electronic medical records. Farm exposure was assessed by comparing the study area with the control area, and with individual exposure estimates in the study area using Geographic Information System data. RESULTS The exacerbation rate was higher in the study area compared with the control area in COPD (IRR: 1.28; 95%CI: 1.06-1.55), but not in asthma patients (IRR: 0.87; 95%CI: 0.72-1.05). In general, individual exposure estimates in the study area were not associated with exacerbations. COPD patients living within a 500m radius of up to12,499 chickens had a 36% higher exacerbation rate (IRR: 1.36; 95%CI: 1.03-1.79). CONCLUSIONS Living in an area with a high livestock density is a risk factor for exacerbations in COPD patients. The environmental exposure responsible for this increased risk remains to be elucidated.

Abstract
Background COPD exacerbations and hospitalizations have been associated with poor prognosis for the COPD patient. Objective To evaluate the frequency and risk factors of COPD exacerbations, hospitalizations, and admissions to intensive care units (ICUs) in Greece by a nationwide cross-sectional study. Materials and methods A nationwide observational, multicenter, cross-sectional study was conducted in the clinical practice setting of respiratory medicine physicians over a 6 month-period (October 2010 to March 2011). A total of 6,125 COPD patients were recruited by 199 respiratory physicians. Results Participants had a median age of 68.0 years, 71.3% were males, and 71.8% suffered from comorbidities. The median disease duration was 10.0 years. Of the patients, 45.3% were classified as having GOLD (Global initiative for chronic Obstructive Lung Disease) stage III or IV COPD. Patients with four or more comorbidities had 78.5% and threefold-higher than expected number of exacerbations and hospitalizations, respectively, as well as fivefold-higher risk of admission to the ICU compared to those with no comorbidities. Obese patients had 6.2% fewer expected exacerbations compared to those with a normal body mass index. Patients with GOLD stage IV had 74.5% and fivefold-higher expected number of exacerbations and hospitalizations, respectively, and nearly threefold-higher risk of admission to the ICU compared to stage I patients. An additional risk factor for exacerbations and hospitalizations was low compliance with treatment: 45% of patients reported forgetting to take their medication, and 81% reported a preference for a treatment with a lower dosing frequency. Conclusion Comorbidities, disease severity, and compliance with treatment were identified as the most notable risk factors for exacerbations, hospitalizations, and ICU admissions. The results point to the need for a multifactorial approach for the COPD patient and for the development of strategies that can increase patient compliance with treatment.

Abstract
Background Chronic obstructive pulmonary disease (COPD) exacerbations account for a substantial proportion of COPD-related costs. Objective To describe COPD exacerbation patterns and assess the association between exacerbation frequency and health care resource utilization (HCRU) and costs in patients with COPD in a Medicare population. Methods A retrospective cohort study utilizing data from a large US national health plan was conducted including patients with a COPD diagnosis during January 1, 2007 to December 31, 2012, aged 40–89 years and continuously enrolled in a Medicare Advantage Prescription Drug plan. Exacerbation frequency, HCRU, and costs were assessed during a 24-month period following the first COPD diagnosis (follow-up period). Four cohorts were created based on exacerbation frequency (zero, one, two, and ≥three). HCRU and costs were compared among the four cohorts using chi-square tests and analysis of variance, respectively. A trend analysis was performed to assess the association between exacerbation frequency and costs using generalized linear models. Results Of the included 52,459 patients, 44.3% had at least one exacerbation; 26.3%, 9.5%, and 8.5% had one, two, and ≥three exacerbations in the 24-month follow-up period, respectively. HCRU was significantly different among cohorts (all P<0.001). In patients with zero, one, two, and ≥three exacerbations, the percentages of patients experiencing all-cause hospitalizations were 49.7%, 66.4%, 69.7%, and 77.8%, respectively, and those experiencing COPD-related hospitalizations were 0%, 40.4%, 48.1%, and 60.5%, respectively. Mean all-cause total costs (medical and pharmacy) were more than twofold greater in patients with ≥three exacerbations compared to patients with zero exacerbations ($27,133 vs $56,033; P<0.001), whereas a greater than sevenfold difference was observed in mean COPD-related total costs ($1,605 vs $12,257; P<0.001). Conclusion COPD patients frequently experience exacerbations. Increasing exacerbation frequency is associated with a multiplicative increase in all-cause and COPD-related costs. This underscores the importance of identifying COPD patients at risk of having frequent exacerbations for appropriate disease management.

Aclidinium bromide and formoterol fumarate as a fixed-dose combination in COPD: pooled analysis of symptoms and exacerbations from two six-month, multicentre, randomised studies (ACLIFORM and AUGMENT). Respir Res 2015; 16:92. [PMID: 26233481 PMCID: PMC4531806 DOI: 10.1186/s12931-015-0250-2] [Citation(s) in RCA: 96] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2015] [Accepted: 07/08/2015] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND The combination of aclidinium bromide, a long-acting anticholinergic, and formoterol fumarate, a long-acting beta2-agonist (400/12 μg twice daily) achieves improvements in lung function greater than either monotherapy in patients with chronic obstructive pulmonary disease (COPD), and is approved in the European Union as a maintenance treatment. The effect of this combination on symptoms of COPD and exacerbations is less well established. We examined these outcomes in a pre-specified analysis of pooled data from two 24-week, double-blind, parallel-group, active- and placebo-controlled, multicentre, randomised Phase III studies (ACLIFORM and AUGMENT). METHODS Patients ≥40 years with moderate to severe COPD (post-bronchodilator forced expiratory volume in 1 s [FEV1]/forced vital capacity <70 % and FEV1 ≥30 % but <80 % predicted normal) were randomised (ACLIFORM: 2:2:2:2:1; AUGMENT: 1:1:1:1:1) to twice-daily aclidinium/formoterol 400/12 μg or 400/6 μg, aclidinium 400 μg, formoterol 12 μg or placebo via Genuair™/Pressair®. Dyspnoea (Transition Dyspnoea Index; TDI), daily symptoms (EXAcerbations of Chronic pulmonary disease Tool [EXACT]-Respiratory Symptoms [E-RS] questionnaire), night-time and early-morning symptoms, exacerbations (Healthcare Resource Utilisation [HCRU] and EXACT definitions) and relief-medication use were assessed. RESULTS The pooled intent-to-treat population included 3394 patients. Aclidinium/formoterol 400/12 μg significantly improved TDI focal score versus placebo and both monotherapies at Week 24 (all p < 0.05). Over 24 weeks, significant improvements in E-RS total score, overall night-time and early-morning symptom severity and limitation of early-morning activities were observed with aclidinium/formoterol 400/12 μg versus placebo and both monotherapies (all p < 0.05). The rate of moderate or severe HCRU exacerbations was significantly reduced with aclidinium/formoterol 400/12 μg compared with placebo (p < 0.05) but not monotherapies; the rate of EXACT-defined exacerbations was significantly reduced with aclidinium/formoterol 400/12 μg versus placebo (p < 0.01) and aclidinium (p < 0.05). Time to first HCRU or EXACT exacerbation was longer with aclidinium/formoterol 400/12 μg compared with placebo (all p < 0.05) but not the monotherapies. Relief-medication use was reduced with aclidinium/formoterol 400/12 μg versus placebo and aclidinium (p < 0.01). CONCLUSIONS Aclidinium/formoterol 400/12 μg significantly improves 24-hour symptom control compared with placebo, aclidinium and formoterol in patients with moderate to severe COPD. Furthermore, aclidinium/formoterol 400/12 μg reduces the frequency of exacerbations compared with placebo. TRIAL REGISTRATION NCT01462942 and NCT01437397 (ClinicalTrials.gov).

Abstract
INTRODUCTION Asymmetric dimethylarginine (ADMA) and nitric oxide (NO) show their mechanism of action reciprocally, the balance between these molecules contributes to the tight regulation of airways tone and function. OBJECTIVES The aim of this study to determine the serum levels of ADMA and NO in patients with chronic obstructive pulmonary disease (COPD) and establish whether their level vary in relation to forced expiratory volume in 1s (FEV1 ), to assess their role in pathophysiology of COPD. MATERIALS AND METHODS This study consisted of 58 patients with COPD and 30 healthy subjects. Serum ADMA and NO levels were measured using enzyme-linked immunosorbent assay and the colorimetric method, respectively. RESULTS Serum ADMA levels were significantly higher, however, NO levels were lower in patients with COPD compared with controls. ADMA levels were inversely correlated with NO levels. Serum ADMA and NO were significantly correlated with FEV1 . Multivariable logistic regression analysis revealed that serum ADMA and NO were independently and significantly associated with the presence of COPD. Multiple linear regression analysis showed that COPD was positively associated with ADMA, additionally COPD and ADMA were independently and inversely associated with NO. NO levels were decreased, ADMA levels were increased compliant with progression of COPD stages. CONCLUSION While circulating ADMA is higher, NO is lower in COPD and both show a strong correlation to the degree of airflow limitation. ADMA seems to be a possible new marker of prognosis of COPD and can be a novel therapeutic target for the treatment of COPD.

Abstract
OBJECTIVES Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, is associated with other chronic conditions, such as congestive heart failure, where it predicts a worse outcome. However, the prevalence of iron deficiency in COPD is unknown. This observational study aimed to determine the prevalence of iron deficiency in COPD and associations with differences in clinical phenotype. SETTING University hospital outpatient clinic. PARTICIPANTS 113 adult patients (65% male) with COPD diagnosed according to GOLD criteria (forced expiratory volume in 1 s (FEV1): forced vital capacity (FVC) ratio <0·70 and FEV1 <80% predicted); with age-matched and sex-matched control group consisting of 57 healthy individuals. MAIN OUTCOME MEASURES Prevalence of iron deficiency, defined as: any one or more of (1) soluble transferrin receptor >28.1 nmol/L; (2) transferrin saturation <16% and (3) ferritin <12 µg/L. Severity of hypoxaemia, including resting peripheral arterial oxygen saturation (SpO2) and nocturnal oximetry; C reactive protein (CRP); FEV1; self-reported exacerbation rate and Shuttle Walk Test performance. RESULTS Iron deficiency was more common in patients with COPD (18%) compared with controls (5%). In the COPD cohort, CRP was higher in patients with iron deficiency (median 10.5 vs 4.0 mg/L, p<0.001), who were also more hypoxaemic than their iron-replete counterparts (median resting SpO2 92% vs 95%, p<0.001), but haemoglobin concentration did not differ. Patients with iron deficiency had more self-reported exacerbations and a trend towards worse exercise tolerance. CONCLUSIONS Non-anaemic iron deficiency is common in COPD and appears to be driven by inflammation. Iron deficiency associates with hypoxaemia, an excess of exacerbations and, possibly, worse exercise tolerance, all markers of poor prognosis. Given that it has been shown to be beneficial in other chronic diseases, intravenous iron therapy should be explored as a novel therapeutic option in COPD.

Abstract
Background: Many cases of chronic obstructive pulmonary disease (COPD) are diagnosed only after significant loss of lung function or during exacerbations. Aims: This study is part of a multi-method approach to develop a new screening instrument for identifying undiagnosed, clinically significant COPD in primary care. Methods: Subjects with varied histories of COPD diagnosis, risk factors and history of exacerbations were recruited through five US clinics (four pulmonary, one primary care). Phase I: Eight focus groups and six telephone interviews were conducted to elicit descriptions of risk factors for COPD, recent or historical acute respiratory events, and symptoms to inform the development of candidate items for the new questionnaire. Phase II: A new cohort of subjects participated in cognitive interviews to assess and modify candidate items. Two peak expiratory flow (PEF) devices (electronic, manual) were assessed for use in screening. Results: Of 77 subjects, 50 participated in Phase I and 27 in Phase II. Six themes informed item development: exposure (smoking, second-hand smoke); health history (family history of lung problems, recurrent chest infections); recent history of respiratory events (clinic visits, hospitalisations); symptoms (respiratory, non-respiratory); impact (activity limitations); and attribution (age, obesity). PEF devices were rated easy to use; electronic values were significantly higher than manual (P<0.0001). Revisions were made to the draft items on the basis of cognitive interviews. Conclusions: Forty-eight candidate items are ready for quantitative testing to select the best, smallest set of questions that, together with PEF, can efficiently identify patients in need of diagnostic evaluation for clinically significant COPD.

Abstract
Exacerbations of chronic obstructive pulmonary disease (COPD) have important consequences for lung function, health status and mortality. Furthermore, they are associated with high economic costs, predominantly related to hospitalization. They are managed acutely with short-acting bronchodilators, systemic corticosteroids or antibiotics; however, a large proportion of COPD exacerbations are unreported and therefore untreated or self-managed. There is evidence to suggest that these unreported exacerbations also have important consequences for health status; therefore, reducing exacerbation risk is an important goal in the management of COPD. Current guidelines recommend long-acting muscarinic antagonists (LAMAs) as first-line bronchodilator therapy in patients with stable COPD who have a high risk of exacerbation or increased symptoms. To date, three LAMAs, tiotropium bromide, aclidinium bromide and glycopyrronium bromide, have been approved as maintenance bronchodilator treatments for stable COPD. These all provide clinically significant improvements in lung function, reduce symptoms and improve health status compared with placebo in patients with COPD. This paper reviews evidence from randomized, controlled clinical trials demonstrating that tiotropium, aclidinium and glycopyrronium reduce exacerbation risk in patients with COPD. Reductions were seen irrespective of the exacerbation measure used, whether time to first event or annualized exacerbation rate. Furthermore, studies with aclidinium suggest LAMAs can reduce exacerbation risk irrespective of whether exacerbation events are assessed, using an event-based approach or a symptom-based method which includes unreported events. Together these results demonstrate that LAMAs have the potential to provide clinical benefit in the management of exacerbations in patients with stable COPD.

Abstract
Background: Patients hospitalized for chronic obstructive pulmonary disease (COPD) exacerbations carry a high risk for early rehospitalization. We wished to identify the basic clinical factors associated with a high risk of rehospitalization, and to see how well the standardized All Patient Refined Diagnosis Related Group (APR-DRG) severity of illness (SOI) subclassification predicted rehospitalization if combined with other simple clinical measures. Methods: We identified adult patients aged ≥40 years discharged from a major hospital in the Southwestern USA with a COPD discharge diagnosis during the study index period (1 October 2009 to 30 September 2010). Patients readmitted within 30 days (“early rehospitalization”) and 90 days (“any rehospitalization”) were each compared with those not rehospitalized. Clinical parameters (including demographics, comorbidities) and recent healthcare utilization were examined for their association with rehospitalization. Factors independently associated with rehospitalization were then combined with the index admission APR-DRG SOI assessment using conditional linear regression to find the best models in terms of the highest C-statistic. Results: Among 306 patients hospitalized for COPD, 62 (20.3%) had a rehospitalization within 90 days and 28 (9.2%), an early readmission. An APR-DRG SOI subclassification ≥3 was a modest independent predictor of early or any readmission, with adjusted odds ratios ranging from 2.09 to 3.33. Models that combined the APR-DRG SOI subclassification with clinical factors present before the index hospitalization had strong C-statistics of ≥0.80. Good models without the APR-DRG SOI subclassification but including a history of recent hospitalizations before the index hospitalization were also identified. Conclusions: An APR-DRG SOI subclassification of ≥3 for the index COPD admission is associated with an increased risk of early rehospitalizations, and can be combined with a few historical clinical factors to create strong predictive models for rehospitalization. This study demonstrates that hospitals can use commonly collected clinical information to help identify COPD patients at a high risk of failure after discharge.

Abstract
BACKGROUND In addition to smoking, acute exacerbations are considered to be a contributing factor to progression of chronic obstructive pulmonary disease (COPD). However, these findings come from studies including active smokers, while results in ex-smokers are scarce and contradictory. The purpose of this study was to evaluate if frequent acute moderate exacerbations are associated with an accelerated decline in forced expiratory volume in one second (FEV1) and impairment of functional and clinical outcomes in ex-smoking COPD patients. METHODS A cohort of 100 ex-smoking patients recruited for a 2-year follow-up study was evaluated at inclusion and at 6-monthly scheduled visits while in a stable condition. Evaluation included anthropometry, spirometry, inspiratory capacity, peripheral capillary oxygen saturation, severity of dyspnea, a 6-minute walking test, BODE (Body mass index, airflow Obstruction, Dyspnea, Exercise performance) index, and quality of life (St George's Respiratory Questionnaire and Chronic Respiratory Disease Questionnaire). Severity of exacerbation was graded as moderate or severe according to health care utilization. Patients were classified as infrequent exacerbators if they had no or one acute exacerbation/year and frequent exacerbators if they had two or more acute exacerbations/year. Random effects modeling, within hierarchical linear modeling, was used for analysis. RESULTS During follow-up, 419 (96% moderate) acute exacerbations were registered. At baseline, frequent exacerbators had more severe disease than infrequent exacerbators according to their FEV1 and BODE index, and also showed greater impairment in inspiratory capacity, forced vital capacity, peripheral capillary oxygen saturation, 6-minute walking test, and quality of life. However, no significant difference in FEV1 decline over time was found between the two groups (54.7±13 mL/year versus 85.4±15.9 mL/year in frequent exacerbators and infrequent exacerbators, respectively). This was also the case for all other measurements. CONCLUSION Our results suggest that frequent moderate exacerbations do not contribute to accelerated clinical and functional decline in COPD patients who are ex-smokers.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory condition, and progresses with acute exacerbations. (AE). During AE, levels of acute phase reactants such as C-reactive protein (CRP) and inflammatory cells in the circulation increase. Soluble urokinase-type plasminogen activator receptor (suPAR) levels increase in acute viral and bacterial infections and in diseases involving chronic inflammation. The purpose of this study was to investigate the effectiveness of suPAR in predicting diagnosis of AE of COPD (AE-COPD) and response to treatment. METHODS The study population consisted of 43 patients diagnosed with AE-COPD and 30 healthy controls. suPAR, CRP, and fibrinogen levels were measured on the first day of hospitalization and on the seventh day of treatment. RESULTS We found that fibrinogen (P<0.001), CRP (P<0.001), and suPAR (P<0.001) were significantly higher in patients with AE-COPD than in healthy controls. Fibrinogen (P<0.001), CRP (P=0.001), and suPAR (P<0.001) were significantly decreased by the seventh day of treatment. However, the area under receiver operator characteristic curve showed that suPAR is superior to CRP and fibrinogen in distinguishing AE-COPD. There was a correlation between fibrinogen, CRP, and suPAR. However, only fibrinogen was a powerful predictor of suPAR in multiple linear regression. In multiple logistic regression, only suPAR and fibrinogen were strong predictors of AE-COPD (P=0.002 and P=0.014, respectively). Serum suPAR was negatively correlated with forced expiratory volume in 1 second (r=-478, P=0.001). CONCLUSION suPAR is a marker of acute inflammation. It is well correlated with such inflammation markers as CRP and fibrinogen. suPAR can be used as a predictor of AE-COPD and in monitoring response to treatment.

Abstract
BACKGROUND The 'frequent exacerbator' is recognised as an important phenotype in COPD. Current understanding about this phenotype comes from prospective longitudinal clinical trials in secondary/tertiary care with little information reported in primary care populations. AIMS To characterize the frequent-exacerbator phenotype and identify associated risk factors in a large UK primary care COPD population. METHODS Using a large database of primary care patients from 80 UK general practices, patients were categorised using GOLD 2014 criteria into high and low risk groups based on exacerbation history. A multivariate logistic regression model was used to investigate covariates associated with the frequent-exacerbator phenotype and risk of experiencing a severe exacerbation (leading to hospitalisation). RESULTS Of the total study population (n = 9219), 2612 (28%) fulfilled the criteria for high risk frequent-exacerbators. Independent risk factors (adjusted odds ratio [95% CI]) for ≥2 exacerbations were: most severely impaired modified Medical Research Council (mMRC) dyspnoea score (mMRC grade 4: 4.37 [2.64-7.23]), lower FEV1 percent predicted (FEV1 <30%: 2.42 [1.61-3.65]), co-morbid cardiovascular disease (1.42 [1.19-1.68]), depression (1.56 [1.22-1.99]) or osteoporosis (1.54 [1.19-2.01]), and female gender (1.20 [1.01-1.43]). Older patients (≥75 years), those with most severe lung impairment (FEV1 <30%), those with highest mMRC score and those with co-morbid osteoporosis were identified as most at risk of experiencing exacerbations requiring hospitalisation. CONCLUSIONS Although COPD exacerbations occur across all grades of disease severity, female patients with high dyspnoea scores, more severely impaired lung function and co-morbidities are at greatest risk. Elderly patients, with severely impaired lung function, high mMRC scores and osteoporosis are associated with experience of severe exacerbations requiring hospitalisation.

Abstract
BACKGROUND Arformoterol tartrate (arformoterol, 15 μg bid) is a nebulized long-acting β2-agonist approved for maintenance treatment of COPD. METHODS This was a multicenter, double-blind, randomized, placebo-controlled study. Patients (aged ≥ 40 years with baseline FEV1 ≤ 65% predicted, FEV1 > 0.50 L, FEV1/FVC ≤ 70%, and ≥ 15 pack-year smoking history) received arformoterol (n = 420) or placebo (n = 421) for 1 year. The primary assessment was time from randomization to respiratory death or first COPD exacerbation-related hospitalization. RESULTS Among 841 patients randomized, 103 had ≥ 1 primary event (9.5% vs 15.0%, for arformoterol vs placebo, respectively). Patients who discontinued treatment for any reason (39.3% vs 49.9%, for arformoterol vs placebo, respectively) were followed for up to 1 year postrandomization to assess for primary events. Fewer patients receiving arformoterol than placebo experienced COPD exacerbation-related hospitalizations (9.0% vs 14.3%, respectively). Twelve patients (2.9%) receiving arformoterol and 10 patients (2.4%) receiving placebo died during the study. Risk for first respiratory serious adverse event was 50% lower with arformoterol than placebo (P = .003). Numerically more patients on arformoterol (13; 3.1%) than placebo (10; 2.4%) experienced cardiac serious adverse events; however, time-to-first cardiac serious adverse event was not significantly different. Improvements in trough FEV1 and FVC were greater with arformoterol (least-squares mean change from baseline vs placebo: 0.051 L, P = .030 and 0.075 L, P = .018, respectively). Significant improvements in quality of life (overall St. George's Hospital Respiratory Questionnaire and Clinical COPD Questionnaire) were observed with arformoterol vs placebo (P < .05). CONCLUSIONS Arformoterol demonstrated an approximately 40% lower risk of respiratory death or COPD exacerbation-related hospitalization over 1 year vs placebo. Arformoterol was well-tolerated and improved lung function vs placebo. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT00909779; URL: www.clinicaltrials.gov.

[PMID: 25485151 PMCID: PMC4251077 DOI: 10.1155/2014/329476] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Revised: 11/03/2014] [Accepted: 11/04/2014] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The course of chronic obstructive pulmonary disease (COPD) is accompanied by acute exacerbations. The purpose of this study is to determine the association of serum magnesium level with acute exacerbations in COPD (COPD-AE). MATERIALS AND METHODS Eighty-nine patients hospitalized with COPD-AE were included. Hemogram, biochemical tests, and arterial blood gases were analyzed. Pulmonary function tests were performed in the stable period after discharge. Patients were followed up at 3 monthly periods for one year. RESULTS Mean age of the patients was 70.4 ± 7.8 (range 47-90) years. Mean number of COPD-AE during follow-up was 4.0 ± 3.6 (range 0-15). On Spearman correlation analysis there were significant negative correlations between number of COPD-AE and predicted FEV1% (P = 0.001), total protein (P = 0.024), globulin (P = 0.001), creatinine (P = 0.001), and uric acid levels (P = 0.036). There were also significant positive correlations between number of COPD-AE and serum magnesium level (P < 0.001) and platelet count (P = 0.043). According to linear regression analysis predicted FEV1% (P = 0.011), serum magnesium (P < 0.001), and globulin (P = 0.006) levels were independent predictors of number of COPD-AE. CONCLUSIONS In this small prospective observational study we found that serum magnesium level during exacerbation period was the most significant predictor of frequency of COPD-AE.
