    To compare the occupational exposure levels assigned by our National Institute for Occupational Safety and Health chronic obstructive pulmonary disease-specific job exposure matrix (NIOSH COPD JEM) and by expert evaluation of detailed occupational information for various jobs held by members of an integrated health plan in the Northwest USA. We analysed data from a prior study examining COPD and occupational exposures. Jobs were assigned exposure levels using 2 methods: (1) the COPD JEM and (2) expert evaluation. Agreement (Cohen's κ coefficients), sensitivity and specificity were calculated to compare exposure levels assigned by the 2 methods for 8 exposure categories. κ indicated slight to moderate agreement (0.19-0.51) between the 2 methods and was highest for organic dust and overall exposure. Sensitivity of the matrix ranged from 33.9% to 68.5% and was highest for sensitisers, diesel exhaust and overall exposure. Specificity ranged from 74.7% to 97.1% and was highest for fumes, organic dust and mineral dust. This COPD JEM was compared with exposures assigned by experts and offers a generalisable approach to assigning occupational exposure. Published by the BMJ Publishing Group Limited.

    Although chronic respiratory disorders are important causes of morbidity and mortality, health care workers, patients and caretakers are not well informed about these disorders. Therefore these problems are underdiagnosed and undertreated; also preventive measures are not widely taken. Our aim was to evaluate the knowledge of asthma and chronic obstructive pulmonary disease (COPD) in Turkey. This study was designed and performed as a Global Alliance Against Respiratory Disorders (GARD) project. People greater than 15 years of age who lived in cities with a population of 200 or greater were eligible for the study. A questionnaire including demographic data and questions regarding asthma and COPD was used for the evalution of the participants. 12.000 people were selected (6000 in rural and 6000 in urban areas); 8527 people were reached. 8342 people who completed the questionnaire were included to the study. There were 4182 (50.1%) female and 4160 (%49.9) male subjects. 49.6% of the subjcets knew that COPD is a lung disease, 51.1% indicated that smoking is the most important risk factor for COPD and 48% identified quitting smoking as the most important preventive measure. Every other person had baseline knowledge on COPD. However only 25.2% knew that there are treatment options for COPD. 80% of subjects said astma can be seen in all age groups. 51.1% knew asthma is a genetic disease and 58% said it is not an infectious disease. However when whether asthma medications caused drug dependency only 27% answered as "No" while 55.2% said "They do not know". Awareness of COPD and asthma seem to be infsufficient among Turkish people. Since these disorders are important causes of morbidity and mortality and have high impact on work and economic loss, it is important to increase knowledge among public.

    Chronic obstructive pulmonary disease (COPD) is one of the serious late pulmonary complications caused by sulphur mustard exposure. Health status evaluations of chemical warfare patients with COPD are important to the management of these patients. The aim of this study was to determine the efficacy of the COPD assessment test (CAT) in evaluating the health-related quality of life (HRQOL) of chemical warfare patients with COPD. Eighty-two consecutive patients with stable COPD were enrolled in this study. All subjects were visited by one physician, and the HRQOL was evaluated by the CAT and St. George Respiratory Questionnaires (SGRQs). In addition, a standard spirometry test, 6-min walk distance test and pulse oxymetry were conducted. The severity of the COPD was determined using Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging and the body mass index, obstruction, dyspnoea and exercise (BODE) index. The mean age of the patients was 47.30 ± 7.08 years. The mean CAT score was 26.03 ± 8.28. Thirty-five (43%) patients were in CAT stage 3. There were statistically significant correlations between the CAT and the SGRQ (r = 0.70, P = 0.001) and the BODE index (r = 0.70, P = 0.001). A statistically significant inverse correlation was found between the CAT score and the forced expiratory volume in 1 s (r = -0.30, P = 0.03). Our results demonstrated that the CAT is a simple and valid tool for assessment of HRQOL in chemical warfare patients with COPD and can be used in clinical practice. © 2013 John Wiley & Sons Ltd.

    COPD is one of the most common causes of morbidity and mortality. Perhaps paradoxically, COPD also should be an orphan disease. Importantly, this could advance the development of treatments for COPD. There are two criteria for orphan status in the United States. Most widely known is the criterion...... of COPD should qualify for the first criterion if the various conditions that comprise COPD are regarded separately. The subphenotyping of COPD into separate...... groups based on mechanism sets the stage for the rational development of therapeutics. In addition, many candidate treatments may alter the natural history of COPD. Testing them, however, will require large studies for a duration that will compromise the commercial life of any resulting product. Orphan...

    Full Text Available OBJECTIVE: To determine the prevalence of atopy and to evaluate clinical, laboratory, and radiological profiles in patients with COPD. METHODS: This was a cross-sectional study involving outpatients with stable COPD (defined by the clinical history and a post-bronchodilator FEV1/FVC < 70% of the predicted value. The patients completed a questionnaire regarding clinical characteristics and atopy, after which they underwent nasal lavage cytology, skin prick testing, chest X-rays, arterial blood gas analyses, and determination of total serum IgE. RESULTS: Of the 149 subjects studied, 53 (35.6%, 49 (32.8%, and 88 (59.1% presented with nasal eosinophilia, a positive skin prick test result, and symptoms of allergic rhinitis, respectively. Correspondence analysis confirmed these findings, showing two distinct patterns of disease expression: atopy in patients with COPD that was less severe; and no evidence of atopy in those with COPD that was more severe (reduced FEV1 and hyperinflation. There was a statistically significant association between nasal eosinophilia and a positive bronchodilator response. CONCLUSIONS: Using simple and reproducible methods, we were able to show that there is a high frequency of atopy in patients with COPD. Monitoring inflammation in the upper airways can be a useful tool for evaluating respiratory diseases in the elderly and in those with concomitant asthma and COPD, a clinical entity not yet fully understood.

    Chronic obstructive pulmonary disease (COPD) is a serious chronic condition with a global impact. Symptoms of COPD include progressive dyspnea, breathlessness, cough, and sputum production, which have a considerable impact on the lives of patients. In addition to the human cost of living with COPD and the resulting death, COPD entails a huge economic burden on the Chinese population, with patients spending up to one-third of the average family income on COPD management in some regions is clinically beneficial to adopt preventable measures via prudent COPD care utilization, monetary costs, and hospitalizations. Toward this end, this study compared the relative effectiveness of six indices in predicting patient healthcare utilization, cost of care, and patient health outcome. The six assessment systems evaluated included the three multidimensional Body mass index, Obstruction, Dyspnea, Exercise capacity index, Dyspnea, Obstruction, Smoking, Exacerbation (DOSE) index, and COPD Assessment Test index, or the unidimensional measures that best predict the future of patient healthcare utilization, cost of care, and patient health outcome among Chinese COPD patients. Multiple linear regression models were created for each healthcare utilization, cost, and outcome including a single COPD index and the same group of demographic variables for each of the outcomes. We conclude that the DOSE index facilitates the prediction of patient healthcare utilization, disease expenditure, and negative clinical outcomes. Our study indicates that the DOSE index has a potential role beyond clinical predictions. Copyright©2018. The Korean Academy of Tuberculosis and Respiratory Diseases.

    The primary aim of the disease management program (DMP) for patients with COPD is to improve health outcomes and thereby to reduce overall costs. Six years after its introduction in Germany, no consensus has yet been reached as to whether the DMP has been effective in reaching these goals. The objective of the study was an evaluation of the DMP for COPD in Bavaria using routinely collected subject medical records. A longitudinal population-based study, comparing the total DMP population of up to 86,560 patients with a stable cohort of 17,549 subjects over a period of 5 years. The effect of subject dropout in the cohort is further estimated by means of inverse probability weighting. The proportion of subjects in the total population who were prescribed and received treatment with oral corticosteroids declined at a constant rate of 1.0% per year (P management education. While the proportion of smokers in the total population remained constant because of the effect of newly enrolled subjects, the proportion of smokers decreased significantly even after dropout adjustment, from 29% to 21%. The occurrence of exacerbations decreased steadily at a rate of 0.9% (total population) or 0.7% (cohort) per year. While the occurrence of emergency hospital admissions decreased in the total population, an increase was observed within the cohort. Summarizing all results leads to the suggestion that the German DMP for COPD has been effective in enhancing the quality of care in regard to an improved adherence to guidelines, pharmacotherapy, exacerbations, and self-management education. However, the DMP was not able to prevent an increase in emergency hospital admissions for the stable population in the cohort. Copyright © 2014 by Daedalus Enterprises.

    The inflammatory profile of chronic obstructive pulmonary disease (COPD) related to tobacco is known in certain studies while that of the post tuberculosis form is not yet known. This study aimed to evaluate the levels of neutrophils, macrophages and lymphocytes cells in sputum of COPD patients with history of smoking or anterior tuberculosis. Enumeration of cells in samples was analyzed using standard microscopy. We enrolled 92 participants, 46 (50%) were COPD subjects comprising 22 (47.83%) smokers and 24 (52.17%) with anterior tuberculosis while 46 (50%) healthy persons constituted the control group. The levels of neutrophils, lymphocytes and monocytes were statistically higher in COPD patients compared to the control group with p-values of 0.0001 respectively. Neutrophils levels were higher in COPD patients with history of tobacco than in COPD patients with anterior tuberculosis with a mean rate of 4.72 × 10 6 /ml and 2.48 × 10 6 /ml respectively (p = 0.04). The monocytes and lymphocytes levels were not statistically different between the two sub-groups of COPD patients with p-value of 0.052 and 0.91 respectively. Neutrophils are the only inflammatory cells that were significantly higher in COPD patients with history of smoking as compared to COPD patients with anterior tuberculosis.

    Chronic obstructive pulmonary disease (COPD) is a multi-factor disease, which could be caused by many factors, including disturbances of metabolism and protein-protein interactions (PPIs). In this paper, a weighted COPD-related metabolic network and a weighted COPD-related PPI network were constructed base on COPD disease genes and functional information. Candidate genes in these weighted COPD-related networks were prioritized by making use of a gene prioritization method, respectively. Literature review and functional enrichment analysis of the top 100 genes in these two networks suggested the correlation of COPD and these genes. The performance of our gene prioritization method was superior to that of ToppGene and ToppNet for genes from the COPD-related metabolic network or the COPD-related PPI network after assessing using leave-one-out cross-validation, literature validation and functional enrichment analysis. The top-ranked genes prioritized from COPD-related metabolic and PPI networks could promote the better understanding about the molecular mechanism of this disease from different perspectives. The top 100 genes in COPD-related metabolic network or COPD-related PPI network might be potential markers for the diagnosis and treatment of COPD.

    Chronic obstructive pulmonary disease (COPD) is a progressive, chronic disease, in which malnutrition can have an undesirable effect. Therefore, the patient's nutritional status is critical for optimizing outcomes in COPD. The initial nutrition assessment is focused on identifying calorically compromised COPD patients in order to provide them with appropriate nutrition. Nutritional intervention consists of oral supplementation and enteral nutrition to prevent weight loss and muscle mass depletion. Evaluation of nutritional status should include past medical history (medications, lung function, and exercise tolerance) and dietary history (patient's dietary habits, food choices, meal patterns, food allergy information, and malabsorption issues), in addition to physiological stress, visceral proteins, weight, fat-free mass, and body mass index. The current medical literature conflicts regarding the appropriate type of formulation to select for nutritional intervention, especially regarding the amount of calories from fat to provide COPD patients. This review article focuses on the enteral product formulations currently available, and how they are most appropriately utilized in patients with COPD.

The purpose of this study was to evaluate techniques for using inhaler devices in COPD patients.Methods: A prospective cross-sectional study was conducted to assess patient compliance with correct techniques for using inhaler devices across four regimens, ie, the pressurized metered-dose inhaler (pMDI, the pMDI with a spacer, the Accuhaler®, and the Handihaler®. The percentage of compliance with essential steps of correct device usage for each regimen was recorded without prior notification when COPD patients presented for a routine visit, and 1 month after receiving face-to-face training. We compared the percentage of compliance between the devices and risk factors related to incorrect techniques using logistic regression analysis. Percentage of patient compliance with correct techniques was compared between the two visits using the chi-square test. Statistical significance was set at P<0.05.Results: A total of 103 COPD patients (mean age 71.2±9.2 years, males 64.1%, low education level 82.5%, and percent predicted forced expiratory volume in 1 second 51.9±22.5 were evaluated. Seventy-seven patients (74.8% performed at least one step incorrectly.

    Full Text Available Nutrition is an important health element for elderly people and influence aging process. Malnutrition prevalence is increasing in this population. Chronic Obstructive Pulmonary Disease (COPD is one of the chronic diseases in elderly that is related to malnutrition. The association between malnutrition and pulmonary disease (including COPD has been known for a long time. Malnutrition has negative impacts on pulmonary structure, elasticity, and function, strength and endurance of respiratory muscles, pulmonary immunity defense mechanism, and breath control. Inversely, pulmonary disease (including COPD will increase energy need and may reduce dietary intake. Nutrition intervention in COPD patient is intended for regulating anorexia, improving pulmonary function, and controlling weight loss. Nutrient requirements will be calculated according to the results of nutrition assessment. This article will discuss about nutrition therapy in elderly with COPD. It describes respiratory system in aging, association COPD and nutrition, and nutrition assessment, as well as nutrition intervention in elderly people with COPD.

    Full Text Available ABSTRACT Objective: To assess and compare the prevalence of comorbidities and risk factors for cardiovascular disease (CVD in COPD patients according to disease severity. Methods: The study included 25 patients with mild-to-moderate COPD (68% male; mean age, 65 ± 8 years; mean FEV1, 73 ± 15% of predicted and 25 with severe-to-very severe COPD (males, 56%; mean age, 69 ± 9 years; mean FEV1, 40 ± 18% of predicted. Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. Comorbidities were registered on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS score was determined. Results: Of the 50 patients evaluated, 38 (76% had been diagnosed with at least one comorbidity, 21 (42% having been diagnosed with at least one CVD. Twenty-four patients (48% had more than one CVD. Eighteen (36% of the patients were current smokers, 10 (20% had depression, 7 (14% had dyslipidemia, and 7 (14% had diabetes mellitus. Current smoking, depression, and dyslipidemia were more prevalent among the patients with mild-to-moderate COPD than among those with severe-to-very severe COPD (p < 0.001, p = 0.008, and p = 0.02, respectively. The prevalence of high blood pressure, diabetes mellitus, alcoholism, ischemic heart disease, and chronic heart failure was comparable between the two groups. The Charlson comorbidity index and HADS scores did not differ between the groups. Conclusions: Comorbidities are highly prevalent in COPD, regardless of its severity. Certain risk factors for CVD, themselves classified as diseases (including smoking, dyslipidemia, and depression, appear to be more prevalent in patients with mild-to-moderate COPD.

    Chronic obstructive pulmonary disease (COPD) is one of the main contributors to the global burden of disease. The aim of this systematic review was to quantify the disease burden of COPD in China and to determine the risk factors of the disease. The number of studies included in the review was 47 with an average quality assessment score of 7.70 out of 10. Reported COPD prevalence varied between 1.20% and 8.87% in different provinces/cities across China. The prevalence rate of COPD was higher among men (7.76%) than women (4.07%). The disease was more prevalent in rural areas (7.62%) than in urban areas (6.09%). The diagnostic rate of COPD patients in China varied from 23.61% to 30.00%. The percentage of COPD patients receiving outpatient treatment was around 50%, while the admission rate ranged between 8.78% and 35.60%. Tobacco exposure and biomass fuel/solid fuel usage were documented as two important risk factors of COPD. COPD ranked among the top three leading causes of death in China. The direct medical cost of COPD ranged from 72 to 3,565 USD per capita per year, accounting for 33.33% to 118.09% of local average annual income. The most commonly used scales for the assessment of quality of life (QoL) included Saint George Respiratory Questionnaire, Airways Questionnaire 20, SF-36, and their revised versions. The status of QoL was worse among COPD patients than in non-COPD patients, and COPD patients were at higher risks of depression. The COPD burden in China was high in terms of economic burden and QoL. In view of the high smoking rate and considerable concerns related to air pollution and smog in China, countermeasures need to be taken to improve disease prevention and management to reduce disease burdens raised by COPD.

    Spirometry is known to be a gold standard for the diagnosis of chronic obstructive pulmonary disease (COPD). COPD Assessment Test (CAT) is an eight-item questionnaire currently in use to evaluate patients with COPD. In the present study, we aimed to evaluate if CAT is an adequate tool for screening COPD. In total, 600 persons aging ⩾40 years old were randomly selected from three different family practice units located in the city center. CAT was asked to the participants and a spirometry was used to assess pulmonary obstruction. Pulmonary obstruction was defined as forced expiratory volume in first second/forced vital capacity (FEV1/FVC)COPD diagnosis was confirmed with the reversibility test. The relationship between CAT results and pulmonary function test values was evaluated. In this sampling, the prevalence of COPD was 4.2%. Reliability of the CAT in the study group was acceptable (Cronbach's α: 0.84). The CAT scores was significantly higher in patients with COPD (PCOPD. CAT is a reliable questionnaire and there is an apparent relationship between the total CAT scores and COPD. However, CAT's ability to screen COPD is limited since it may miss the symptom-free cases.

    Chronic Obstructive Pulmonary Disease is the third leading cause of death in the US, and is associated with periodic exacerbations, which account for the largest proportion of health care utilization, and lead to significant morbidity, mortality, and worsening lung function. A subset of patients with COPD have frequent exacerbations, occurring 2 or more times per year. Despite many interventions to reduce COPD exacerbations, there is a significant lack of knowledge in regards to their mechanisms and predisposing factors. We describe here an important observation that defines antibody deficiency as a potential risk factor for frequent COPD exacerbations. We report a case series of patients who have frequent COPD exacerbations, and who were found to have an underlying primary antibody deficiency syndrome. We also report on the outcome of COPD exacerbations following treatment in a subset with of these patients with antibody deficiency. We identified patients with COPD who had 2 or more moderate to severe exacerbations per year; immune evaluation including serum immunoglobulin levels and pneumococcal IgG titers was performed. Patients diagnosed with an antibody deficiency syndrome were treated with either immunoglobulin replacement therapy or prophylactic antibiotics, and their COPD exacerbations were monitored over time. A total of 42 patients were identified who had 2 or more moderate to severe COPD exacerbations per year. Twenty-nine patients had an underlying antibody deficiency syndrome: common variable immunodeficiency (8), specific antibody deficiency (20), and selective IgA deficiency (1). Twenty-two patients had a follow-up for at least 1 year after treatment of their antibody deficiency, which resulted in a significant reduction of COPD exacerbations, courses of oral corticosteroid use and cumulative annual dose of oral corticosteroid use, rescue antibiotic use, and hospitalizations for COPD exacerbations. This case series identifies antibody deficiency as a

The percentage of COPD patients receiving outpatient treatment was around 50%, while the admission rate ranged between 8.78% and 35.60%. Tobacco exposure and biomass fuel/solid fuel usage were documented as two important risk factors of COPD. COPD ranked among the top three leading causes of death in China. The direct medical cost of COPD ranged from 72 to 3,565 USD per capita per year, accounting for 33.33% to 118.09% of local average annual income. The most commonly used scales for the assessment of quality of life (QoL included Saint George Respiratory Questionnaire, Airways Questionnaire 20, SF-36, and their revised versions. The status of QoL was worse among COPD patients than in non-COPD patients, and COPD patients were at higher risks of depression. The COPD burden in China was high in terms of economic burden and QoL. In view of the high smoking rate and considerable concerns related to air pollution and smog in China, countermeasures

    Adherence to guidelines for managing stable chronic obstructive pulmonary disease (COPD) and its exacerbations is inadequate among healthcare workers and patients. An appropriate care model would meet patient needs, enhance their coping with COPD and improve their quality of life (QOL). This study aims to present the 'COPD-Home' as an integrated care model for patients with severe or very severe COPD. One principle of the COPD-Home model is that hospital treatment should lead to follow up in the patient's home. The model also includes education, improved coordination of levels of care, improved accessibility and a management plan. One of the main elements of the COPD-Home model is the clear role of the home-care nurse. Model development is based on earlier research and clinical experience. It comprises: (i) education provided through an education programme for patients and involved nurses, (ii) joint visits and telephone checks, (iii) a call centre for support and communication with a general practitioner and (iv) an individualised self-management plan including home monitoring and a plan for pharmacological and nonpharmacological interventions. The COPD-Home model attempts to cultivate competences and behaviours of patients and community nurses that better accord with guidelines for interventions. The next step in its development will be to evaluate its ability to assist both healthcare workers and planners to improve the management of COPD, reduce exacerbations and improve QOL and coping among patients with COPD. © 2013 Nordic College of Caring Science.

    Objective In 2011, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification categorized chronic obstructive pulmonary disease (COPD) patients into 4 groups. A report demonstrated that the mortality in Group B was higher than that in Group C. Ischemic heart disease and cancer were suggested to be the cause. The aim of the present study was to test the hypothesis that interstitial lung abnormalities (ILAs) are more prevalent in Group B than Group C and that they may be responsible for the higher mortality in Group B. Methods Patients were selected based on their pulmonary function test results. The inclusion criterion was a forced expiratory volume in 1 second (FEV 1 )/forced vital capacity (FVC) of COPD patients, ILAs were detected in 10.3% of the patients in Group A, 22.5% of the patients in Group B, 5.6% of the patients in Group C, and 23.1% of the patients in Group D. In Group B, the frequency of ILAs was significantly higher and the area affected by the ILAs was significantly greater in comparison to Group C. Among the patterns of interstitial abnormalities, the area of honeycombing in Group B was significantly greater than that in Group C. Furthermore, among the patients in Group B, the LAA in the ILA-positive patients was significantly greater than that in the ILA-negative patients. Conclusion In Group B, the area occupied by ILAs-especially honeycombing-was greater than that in Group C. This contributed to the preserved %FEV 1 and possibly to the poorer prognosis of the patients in Group B.

    Significant heterogeneity of clinical presentation and disease progression exists within chronic obstructive pulmonary disease (COPD). Although FEV(1) inadequately describes this heterogeneity, a clear alternative has not emerged. The goal of phenotyping is to identify patient groups with unique...... prognostic or therapeutic characteristics, but significant variation and confusion surrounds use of the term "phenotype" in COPD. Phenotype classically refers to any observable characteristic of an organism, and up until now, multiple disease characteristics have been termed COPD phenotypes.

    To assess and compare the prevalence of comorbidities and risk factors for cardiovascular disease (CVD) in COPD patients according to disease severity. The study included 25 patients with mild-to-moderate COPD (68% male; mean age, 65 ± 8 years; mean FEV1, 73 ± 15% of predicted) and 25 with severe-to-very severe COPD (males, 56%; mean age, 69 ± 9 years; mean FEV1, 40 ± 18% of predicted). Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. Comorbidities were registered on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined. Of the 50 patients evaluated, 38 (76%) had been diagnosed with at least one comorbidity, 21 (42%) having been diagnosed with at least one CVD. Twenty-four patients (48%) had more than one CVD. Eighteen (36%) of the patients were current smokers, 10 (20%) had depression, 7 (14%) had dyslipidemia, and 7 (14%) had diabetes mellitus. Current smoking, depression, and dyslipidemia were more prevalent among the patients with mild-to-moderate COPD than among those with severe-to-very severe COPD (p dislipidemia, e 7 (14%) tinham diabetes mellitus. Tabagismo atual, depressão e dislipidemia foram mais prevalentes nos pacientes com DPOC leve/moderada que naqueles com DPOC grave/muito grave (p dislipidemia e depressão), parecem ser mais prevalentes nos pacientes com DPOC leve/moderada.

    Full Text Available Abstract Chronic obstructive pulmonary disease (COPD is one of the leading causes of morbidity and mortality in both industrialized and developing countries. Cigarette smoking is the major risk factor for COPD. However, relevant information from the literature published within the last years, either on general population samples or on workplaces, indicate that about 15% of all cases of COPD is work-related. Specific settings and agents are quoted which have been indicated or confirmed as linked to COPD. Coal miners, hard-rock miners, tunnel workers, concrete-manufacturing workers, nonmining industrial workers have been shown to be at highest risk for developing COPD. Further evidence that occupational agents are capable of inducing COPD comes from experimental studies, particularly in animal models. In conclusion, occupational exposure to dusts, chemicals, gases should be considered an established, or supported by good evidence, risk factor for developing COPD. The implications of this substantial occupational contribution to COPD must be considered in research planning, in public policy decision-making, and in clinical practice.

    Inflammation is central to the development of chronic obstructive pulmonary disease (COPD), a pulmonary disorder characterized by chronic bronchitis, chronic airway obstruction, emphysema, associated to progressive and irreversible decline of lung function. Emerging genetic and pharmacological evidence suggests that IL-1-like cytokines are highly detected in the sputum and broncho-alveolar lavage (BAL) of COPD patients, implying the involvement of the multiprotein complex inflammasome. So far, scientific evidence has focused on nucleotide-binding oligomerization domain-like receptors protein 3 (NLRP3) inflammasome, a specialized inflammatory signaling platform that governs the maturation and secretion of IL-1-like cytokines through the regulation of caspase-1-dependent proteolytic processing. Some studies revealed that it is involved during airway inflammation typical of COPD. Based on the influence of cigarette smoke in various respiratory diseases, including COPD, in this view we report its effects in inflammatory and immune responses in COPD mouse models and in human subjects affected by COPD. In sharp contrast to what reported on experimental and clinical studies, randomized clinical trials show that indirect inflammasome inhibitors did not have any beneficial effect in moderate to severe COPD patients.

    Chronic obstructive pulmonary disease (COPD) and cardiovascular diseases (CV) often coexist. COPD and CVD are complex diseases characterized by a strict interaction between environment and genetic. The mechanisms linking these two diseases are complex, multifactorial and not entirely understood, influencing the therapeutic approach. COPD is characterized by several comorbidities, it is hypothesizable that treatment of cardiovascular co-morbidities may reduce morbidity and mortality. Flavonoids are an important class of plant low molecular weight secondary metabolites (SMs). Convincing data from laboratory, epidemiological, and human clinical studies point to an important effects on CVD risk prevention. This review aims to provide up-to-date information on the ability of Flavonoids to reduce the CVD risk. Current studies support the potential of Flavonoids to prevent the risk of CVD. Well-designed clinical studies are suggested to evaluate advantages and limits of Flavonoids for managing CVD comorbidity in COPD.

    A close relationship between Metabolic Syndrome (MetS) and Chronic Obstructive Pulmonary Disease (COPD) has been described, but the exact nature of this link remains unclear. Current epidemiological data refer exclusively to the MetS prevalence among patients with COPD and data about the prevalence of COPD in MetS patients are still unavailable. To analyse and compare risk factors, clinical and metabolic characteristics, as well as the main respiratory function parameters, among patients affected by MetS, COPD or both diseases. We recruited 59 outpatients with MetS and 76 outpatients with COPD. After medical history collection, physical examination, blood sampling for routine analysis, spirometric evaluation, they were subdivided into MetS (n = 46), MetS+COPD (n = 60), COPD (n = 29). A MetS diagnosis was assigned to 62% of COPD patients recruited in the COPD Outpatients Clinic of the Pneumology Department, while the COPD prevalence in MetS patients enrolled in the Internal Medicine Metabolic Disorders Outpatients Clinic was 22%. More than 60% of subjects enrolled in each Department were unaware that they suffered from an additional disease. MetS+COPD patients exhibited significantly higher C-peptide levels. We also found a positive relation between C-peptide and pack-years in all subjects and a negative correlation between C-peptide and vitamin D only in current smokers. Finally, a negative association emerged between smoking and vitamin D. We have estimated, for the first time, the COPD prevalence in MetS and suggest a potential role of smoking in inducing insulin resistance. Moreover, a direct effect of smoking on vitamin D levels is proposed as a novel mechanism, which may account for both insulin resistance and COPD development.

    Chronic obstructive pulmonary disease (COPD) has substantial economic and human costs; it is expected to be the third leading cause of death worldwide by 2030. To minimize these costs high quality guidelines have been developed. However, guidelines alone rarely result in meaningful change. One method of integrating guidelines into practice is the use of clinical pathways (CPWs). CPWs bring available evidence to a range of healthcare professionals by detailing the essential steps in care and adapting guidelines to the local context. We are working with local stakeholders to develop CPWs for COPD with the aims of improving care while reducing utilization. The CPWs will employ several steps including: standardizing diagnostic training, unifying components of chronic disease care, coordinating education and reconditioning programs, and ensuring care uses best practices. Further, we have worked to identify evidence-informed implementation strategies which will be tailored to the local context. We will conduct a three-year research project using an interrupted time series (ITS) design in the form of a multiple baseline approach with control groups. The CPW will be implemented in two health regions (experimental groups) and two health regions will act as controls (control groups). The experimental and control groups will each contain an urban and rural health region. Primary outcomes for the study will be quality of care operationalized using hospital readmission rates and emergency department (ED) presentation rates. Secondary outcomes will be healthcare utilization and guideline adherence, operationalized using hospital admission rates, hospital length of stay and general practitioner (GP) visits. Results will be analyzed using segmented regression analysis. Funding has been procured from multiple stakeholders. The project has been deemed exempt from ethics review as it is a quality improvement project. Intervention implementation is expected to begin in summer of 2017

    Rationale: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease and likely includes a subgroup that is biologically comparable to asthma. Studying asthma-associated gene expression changes in COPD could add insight into COPD pathogenesis and reveal biomarkers that predict a favorable response to corticosteroids. Objectives: To determine whether asthma-associated gene signatures are increased in COPD and associated with asthma-related features. Methods: We compared disease-associated airway epithelial gene expression alterations in an asthma cohort (n = 105) and two COPD cohorts (n = 237, 171). The T helper type 2 (Th2) signature (T2S) score, a gene expression metric induced in Th2-high asthma, was evaluated in these COPD cohorts. The T2S score was correlated with asthma-related features and response to corticosteroids in COPD in a randomized, placebo-controlled trial, the Groningen and Leiden Universities study of Corticosteroids in Obstructive Lung Disease (GLUCOLD; n = 89). Measurements and Main Results: The 200 genes most differentially expressed in asthma versus healthy control subjects were enriched among genes associated with more severe airflow obstruction in these COPD cohorts (P COPD cohorts. Higher T2S scores correlated with increased airway wall eosinophil counts (P = 0.003), blood eosinophil percentage (P = 0.03), bronchodilator reversibility (P = 0.01), and improvement in hyperinflation after corticosteroid treatment (P = 0.019) in GLUCOLD. Conclusions: These data identify airway gene expression alterations that can co-occur in asthma and COPD. The association of the T2S score with increased severity and “asthma-like” features (including a favorable corticosteroid response) in COPD suggests that Th2 inflammation is important in a COPD subset that cannot be identified by clinical history of asthma.

    Differential diagnosis of chronic obstructive pulmonary disease (COPD) from asthma is not a difficult task for many clinicians. Patients with COPD have a history of heavy smoking and show a slowly progressive dyspnea on exertion and there is little variability in symptoms, and they show a poor response to bronchodilators and corticosteroids. Asthma usually begins in early childhood with atopy, shows episodic dyspnea with wheezing, especially during night and early morning. Some patients, however, show adult onset, irreversible airflow limitation, and neutrophilic airway inflammation. The airway remodeling in asthma may be the cause of confusing pathophysiology. Other diseases showing airway hyperresponsiveness, such as allergic bronchopulmonary aspergillosis, Churg-Strauss syndrome, and left heart failure presenting cardiac asthma, may sometimes show similar clinical pictures to COPD. Chronic airway diseases are also possible candidates for differential diagnosis of COPD. Bronchiectasis, sinobronchial syndrome, diffuse panbronchiolitis, obliterative bronchiolitis, and other chronic airway diseases should be considered. Some interstitial lung diseases, such as smoking-related interstitial lung diseases and lymphangioleiomyomatosis, often show obstructive ventilatory impairment, and therefore should be considered in differential diagnosis of COPD.

    The morning tends to be the most difficult time of day for many patients with chronic obstructive pulmonary disease (COPD) when symptoms can limit one's ability to perform even simple activities. Morning symptoms have been linked to higher levels of work absenteeism, thereby increasing the already substantial economic burden associated with COPD. A validated patient-reported outcome (PRO) instrument designed to capture morning symptoms will allow for a more comprehensive approach to the evaluation of treatment benefit in COPD clinical trials. A qualitative interview study was conducted among a sample of symptomatic adults with COPD. Concept elicitation interviews (n = 35) were conducted to identify COPD morning symptoms, followed by cognitive interviews (n = 21) to ensure patient comprehension of the items, instructions and response options of the draft COPD Morning Symptom Diary (COPD-MSD). All interview transcript data were coded using ATLAS.ti software for content analysis. Mean age of the concept elicitation and cognitive interview sample was 65.0 years (±7.5) and 62.3 years (±8.3), respectively. The study sample represented the full range of COPD severity (Global Initiative for Chronic Lung Disease [GOLD] classifications I-IV) and included a mix of racial backgrounds, employment status and educational achievement. During the concept elicitation interviews, the three most frequently reported morning symptoms were shortness of breath (n = 35/35; 100 %), phlegm/mucus (n = 31/35; 88.6 %), and cough (n = 30/35; 85.7 %). A group of clinical and instrument development experts convened to review the concept elicitation data and develop the initial 32-item draft COPD-MSD. Cognitive interviews indicated subjects found the draft COPD-MSD to be comprehensive, clear, and easy to understand. The COPD-MSD underwent minor editorial revisions and streamlining based on cognitive interviews and input from the experts to yield the final 19-item daily

Gastroesophageal reflux disease (GERD is one of the most common gastrointestinal conditions in the general population and has emerged as a comorbidity of COPD. GERD may be diagnosed by both symptomatic approaches (including both typical and atypical symptoms and objective measurements. Based on a mix of diagnostic approaches, the prevalence of GERD in COPD ranges from 17% to 78%. Although GERD is usually confined to the lower esophagus in some individuals, it may be associated with pulmonary microaspiration of gastric contents. Possible mechanisms that may contribute to GERD in COPD originate from gastroesophageal dysfunction, including altered pressure in the lower esophageal sphincter (which normally protect against GERD and changes in esophageal motility. Proposed respiratory contributions to the development of GERD include respiratory medications that may alter esophageal sphincter tone and changes in respiratory mechanics, with increased lung hyperinflation compromising the antireflux barrier. Although the specific cause and effect relationship between GERD and COPD has not been fully elucidated, GERD may influence lung disease severity and has been identified as a significant predictor of acute exacerbations of COPD. Further clinical effects could include a poorer health-related quality of life and an increased cost in health care, although these factors require further clarification.

    Imbalance between antioxidant and oxidative stress is a major risk factor for pathogenesis of some chronic diseases such as chronic obstructive pulmonary disease (COPD). This study aimed to determine antioxidant and oxidative stress status, and also theirs association with respiratory function of male COPD patients to find the antioxidant predictors' factors. A total of 149 subjects were involved in a cross-sectional study. The study was conducted at two medical centers in Kuala Lumpur, Malaysia. Results of the study showed that plasma vitamin C was low in most of the subjects (86.6%). Total antioxidant capacity was the lowest in COPD stage IV compare to other stages (p < 0.05). Level of plasma vitamin A (p= 0.012) and vitamin C (p= 0.007) were low in malnourished subjects. The predictors for total antioxidant capacity were forced vital capacity (FVC) % predicted and intake of ?-carotene (R2= 0.104, p= 0.002). Number of cigarette (pack/ year) and smoking index (number/ year) were not associated with total antioxidant capacity of this COPD population. Plasma oxidative stress as assessed plasma lipid peroxidation (LPO) was only positively correlated with plasma glutathione (p= 0.002). It might be a need to evaluate antioxidant status especially in older COPD patients to treat antioxidant deficiency which is leading to prevent COPD progression.

    Nighttime symptoms can negatively impact the quality of life of patients with chronic obstructive pulmonary disease (COPD). The Nighttime Symptoms of COPD Instrument (NiSCI) was designed to measure the occurrence and severity of nighttime symptoms in patients with COPD, the impact of symptoms on nighttime awakenings, and rescue medication use. The objective of this study was to explore item reduction, inform scoring recommendations, and evaluate the psychometric properties of the NiSCI. COPD patients participating in a Phase III clinical trial completed the NiSCI daily. Item analyses were conducted using weekly mean and single day scores. Descriptive statistics (including percentage of respondents at floor/ceiling and inter-item correlations), factor analyses, and Rasch model analyses were conducted to examine item performance and scoring. Test-retest reliability was assessed for the final instrument using the intraclass correlation coefficient (ICC). Correlations with assessments conducted during study visits were used to evaluate convergent and known-groups validity. Data from 1,663 COPD patients aged 40-93 years were analyzed. Item analyses supported the generation of four scores. A one-factor structure was confirmed with factor analysis and Rasch analysis for the symptom severity score. Test-retest reliability was confirmed for the six-item symptom severity (ICC, 0.85), number of nighttime awakenings (ICC, 0.82), and rescue medication (ICC, 0.68) scores. Convergent validity was supported by significant correlations between the NiSCI, St George's Respiratory Questionnaire, and Exacerbations of Chronic Obstructive Pulmonary Disease Tool-Respiratory Symptoms scores. The results suggest that the NiSCI can be used to determine the severity of nighttime COPD symptoms, the number of nighttime awakenings due to COPD symptoms, and the nighttime use of rescue medication. The NiSCI is a reliable and valid instrument to evaluate these concepts in COPD patients in clinical

    Alterations in global DNA methylation have been associated with oxidative stress (OS). Since chronic obstructive pulmonary disease (COPD) is characterized by increased oxidative stress we aimed to evaluate the levels of global DNA methylation in this patient group. We assessed methylcytosine (mCyt) levels in DNA from blood collected in 43 COPD patients (29 with mild and 14 with moderate disease) and 43 age- and sex-matched healthy controls. DNA methylation was significantly lower in COPD patients vs. controls (4.20 ± 0.18% mCyt vs. 4.29 ± 0.18% mCyt, p = 0.02). Furthermore, DNA methylation in COPD patients with moderate disease was significantly lower than that in patients with mild disease (4.14 ± 0.15% mCyt vs. 4.23 ± 0.19% mCyt, p COPD (crude OR = 0.06, 95% CI 0.00 to 0.67, p = 0.023). This relationship remained significant after adjusting for several confounders (OR 0.03, 95% CI 0.00 to 0.67; p = 0.028). Receiver operating characteristics (ROC) curve analysis demonstrated the area under the curve of mCyt was 0.646, with 46.6% sensitivity and 79.1% specificity for presence of COPD. There were no significant correlations between methylation and OS indices. The presence and severity of COPD is associated with progressively lower DNA methylation in blood. However, this epigenetic alteration seems independent of oxidative stress. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Chronic obstructive pulmonary disease (COPD) is a life-threatening lung disorder whose recent prevalence has led to an increasing burden on public healthcare. Phenotypic information in electronic clinical records is essential in providing suitable personalised treatment to patients with COPD. However, as phenotypes are often "hidden" within free text in clinical records, clinicians could benefit from text mining systems that facilitate their prompt recognition. This paper reports on a semi-automatic methodology for producing a corpus that can ultimately support the development of text mining tools that, in turn, will expedite the process of identifying groups of COPD patients. A corpus of 30 full-text papers was formed based on selection criteria informed by the expertise of COPD specialists. We developed an annotation scheme that is aimed at producing fine-grained, expressive and computable COPD annotations without burdening our curators with a highly complicated task. This was implemented in the Argo platform by means of a semi-automatic annotation workflow that integrates several text mining tools, including a graphical user interface for marking up documents. When evaluated using gold standard (i.e., manually validated) annotations, the semi-automatic workflow was shown to obtain a micro-averaged F-score of 45.70% (with relaxed matching). Utilising the gold standard data to train new concept recognisers, we demonstrated that our corpus, although still a work in progress, can foster the development of significantly better performing COPD phenotype extractors. We describe in this work the means by which we aim to eventually support the process of COPD phenotype curation, i.e., by the application of various text mining tools integrated into an annotation workflow. Although the corpus being described is still under development, our results thus far are encouraging and show great potential in stimulating the development of further automatic COPD phenotype extractors.

    Patients with cardiovascular disease (CVD) often have multiple comorbid conditions that may interact with each other, confound the choice of treatments, and reduce mortality. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. COPD shares common risk factors such as tobacco smoking and aging with CVD, is associated with less physical activity, and produces systemic inflammation and oxidative stress. Overall, patients with COPD have a 2-3-fold increased risk of CVD as compared to age-matched controls when adjusted for tobacco smoking. Chronic heart failure (HF) is a frequent and important comorbidity which has a significant impact on prognosis in COPD, and vice versa. HF overlaps in symptoms and signs and has a common comorbidity with COPD, so that diagnosis of COPD is difficult in patients with HF. The combination of HF and COPD presents many therapeutic challenges including beta-blockers (BBs) and beta-agonists. Inhaled long-acting bronchodilators including beta2-agonists and anticholinergics for COPD would not worsen HF. Diuretics are relatively safe, and angiotensin-converting enzyme inhibitors are preferred to treat HF accompanied with COPD. BBs are only relatively contraindicated in asthma, but not in COPD. Low doses of cardioselective BBs should be aggressively initiated in clinically stable patients with HF accompanied with COPD combined with close monitoring for signs of airway obstruction and gradually up-titrated to the maximum tolerated dose. Encouraging appropriate and aggressive treatment for both HF and COPD should be recommended to improve quality of life and mortality in HF patients with COPD.

    Hand dexterity is important for daily living activities and can be related to cognitive functions in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the relationship between cognitive dysfunction and hand dexterity in patients with COPD. 35 COPD patients and 36 healthy individuals were assessed. The Minnesota Hand Dexterity Test and Mini Mental State Examination (MMSE) were used for assessment of cognitive function and hand dexterity. Hand dexterity test scores and cognitive function of COPD patients' were significantly lower than the healthy group (p COPD group (p COPD; however, hand dexterity did not alter according to hypoxemia severity. Hand dexterity which is important in daily living activities should be evaluated in greater detail with further studies in COPD patients.

    In Oriental countries, combinations of Chinese herbal products (CHPs) are often utilized as therapeutic agents for chronic obstructive pulmonary disease (COPD). The effects of CHPs on COPD have been previously reported. This study aimed to analyze the frequency of prescription and usage of CHPs in patients with COPD in Taiwan. In this nationwide population-based cross-sectional study, 19,142 patients from a random sample of one million individuals in the Longitudinal Health Insurance Database 2000 (LHID 2000) of the National Health Insurance Research Database (NHIRD) were enrolled from 2000 to 2011. The multiple logistic regression method was used to evaluate the adjusted odds ratios for the utilization of CHPs. For patients with COPD, there was an average of 6.31 CHPs in a single prescription. The most frequently prescribed CHP for COPD was Xiao-Qing-Long-Tang (XQLT) (2.6%), and the most commonly used combination of two formula CHPs was XQLT with Ma-Xing-Gan-Shi-Tang (MXGST) (1.28%). The most commonly used single CHP for COPD was Bulbus Fritillariae (3.65%), and the most commonly used combination of two single CHPs was Bulbus Fritillariae with Puerariae Lobatae (1.09%). These results provide information regarding personalized therapies and may promote further clinical experiments and pharmacologic research on the use of CHPs for the management of COPD. Furthermore, we found that TCM usage was more prevalent among men, younger, manual workers, residents of Northern Taiwan, and patients with chronic bronchitis and asthma. This information on the distribution of TCM usage around the country is valuable to public health policymakers and clinicians.

    Tai Chi, a systematic callisthenic exercise first developed in ancient China, involves a series of slow and rhythmic circular motions. It emphasises use of 'mind' or concentration to control breathing and circular body motions to facilitate flow of internal energy (i.e. 'qi') within the body. Normal flow of 'qi' is believed to be essential to sustain body homeostasis, ultimately leading to longevity. The effect of Tai Chi on balance and muscle strength in the elderly population has been reported; however, the effect of Tai Chi on dyspnoea, exercise capacity, pulmonary function and psychosocial status among people with chronic obstructive pulmonary disease (COPD) remains unclear. • To explore the effectiveness of Tai Chi in reducing dyspnoea and improving exercise capacity in people with COPD.• To determine the influence of Tai Chi on physiological and psychosocial functions among people with COPD. We searched the Cochrane Airways Group Specialised Register of trials (which included the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Allied and Complementary Medicine Database (AMED) and PsycINFO); handsearched respiratory journals and meeting abstracts; and searched Chinese medical databases including Wanfang Data, Chinese Medical Current Contents (CMCC), Chinese Biomedical Database (CBM), China Journal Net (CJN) and China Medical Academic Conference (CMAC), from inception to September 2015. We checked the reference lists of all primary studies and review articles for relevant additional references. We included randomised controlled trials (RCTs) comparing Tai Chi (Tai Chi alone or Tai Chi in addition to another intervention) versus control (usual care or another intervention identical to that used in the Tai Chi group) in people with COPD. Two independent review authors screened and selected studies. Two independent review authors extracted data from included

    To identify features of obstructive airway disease on sagittal reconstruction, compare the accuracy of findings to traditional imaging characteristics of COPD, and determine the fraction of additional cases identified using new characteristics. The study was approved by the centre's Institutional Review Board and is HIPAA compliant. Two hundred sixteen patients with HRCT and spirometry within a 3-month window were included. Four radiologists evaluated each HRCT for traditional characteristics of COPD and new quantitative and qualitative features of obstruction on axial and sagittal reconstructions. Imaging characteristics were assessed for correlation with the spirometric diagnosis of obstructive airway disease. Quantitative and qualitative findings on sagittal reconstruction are highly specific for COPD (specificity >90 %). Features of hyperinflation on sagittal reconstruction are more accurate predictors of obstruction than traditional axial measures, with greater interobserver reliability (hyperinflation left hemidiaphragm: accuracy: 70.08 % ± 2.49 %; kappa: 0.511 versus traditional measures: accuracy: 62.00 % ± 5.38 %; kappa: 0.407). Sagittal reconstruction identified 27-70 % more patients with COPD than traditional axial findings (p < 0.05). Analysis of sagittal reconstruction enables greater accuracy and specificity in the diagnosis of obstructive airway disease compared to traditional measures on axial imaging. Use of sagittal reconstructions can help identify up to 70 % more patients with COPD than traditional imaging findings alone. (orig.)

    Aim To investigate if cardiac/pulmonary functional tests and variables obtained from clinical practice (body mass index, dyspnea, functional class, clinical judgment of disability to perform an exercise test and previous hospitalization rate) are related to mortality in patients with overlap chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF). Although the coexistence of COPD and CHF has been growingly reported, description of survival predictors considering the presence of both conditions is still scarce. Using a cohort design, outpatients with the previous diagnosis of COPD and/or CHF that performed both spirometry and echocardiography in the same year were followed-up during a mean of 20.9±8.5 months. Findings Of the 550 patients initially evaluated, 301 had both spirometry and echocardiography: 160 (53%) with COPD on isolation; 100 (33%) with CHF on isolation; and 41 (14%) with overlap. All groups presented similar mortality: COPD 17/160 (11%); CHF 12/100 (12%); and overlap 7/41 (17%) (P=0.73). In the overlap group (n=41), inability to exercise and hospitalization rate were the unique parameters associated with higher mortality (seven events) in univariate analyses. In conclusion, inability to exercise and hospitalization rate emerged as the unique parameters associated with mortality in our sample.

    in the lung, thereby reducing the driving pressure for expiratory flow through narrowed and poorly supported airways, in which airflow resistance is significantly increased. Expiratory flow limitation is the pathophysiological hallmark of COPD. Exacerbations of COPD contribute considerably to morbidity and mortality, and impose a burden on the health care system. They are a leading cause of emergency room visits and hospitalizations, particularly in the winter. In Canada, the reported average cost for treating a moderate exacerbation is $641; for a major exacerbation, the cost is $10,086. Objective The objective of this study was to evaluate the cost-effectiveness and budget impact of the following interventions in moderate to very severe COPD, investigated in the Medical Advisory Secretariat Chronic Obstructive Pulmonary Disease Mega-Analysis Series: smoking cessation programs in moderate COPD in an outpatient setting: – intensive counselling (IC) versus usual care (UC) – nicotine replacement therapy (NRT) versus UC – IC + NRT versus placebo – bupropion versus placebo multidisciplinary care (MDC) teams versus UC in moderate to severe COPD in an outpatient setting pulmonary rehabilitation (PR) versus UC following acute exacerbations in moderate to severe COPD long-term oxygen therapy (LTOT) versus UC in severe hypoxemia in COPD in an outpatient setting ventilation: – noninvasive positive pressure ventilation (NPPV) + usual medical care versus usual medical care in acute respiratory failure due to an acute exacerbation in severe COPD in an inpatient setting – weaning with NPPV versus weaning with invasive mechanical ventilation in acute respiratory failure due to an acute exacerbation in very severe COPD in an inpatient setting Methods A cost-utility analysis was conducted using a Markov probabilistic model.

The Nighttime Symptoms of COPD Instrument (NiSCI was designed to measure the occurrence and severity of nighttime symptoms in patients with COPD, the impact of symptoms on nighttime awakenings, and rescue medication use. The objective of this study was to explore item reduction, inform scoring recommendations, and evaluate the psychometric properties of the NiSCI.Methods: COPD patients participating in a Phase III clinical trial completed the NiSCI daily. Item analyses were conducted using weekly mean and single day scores. Descriptive statistics (including percentage of respondents at floor/ceiling and inter-item correlations, factor analyses, and Rasch model analyses were conducted to examine item performance and scoring. Test–retest reliability was assessed for the final instrument using the intraclass correlation coefficient (ICC. Correlations with assessments conducted during study visits were used to evaluate convergent and known-groups validity.Results: Data from 1,663 COPD patients aged 40–93 years were analyzed. Item analyses supported the generation of four scores. A one-factor structure was confirmed with factor analysis and Rasch analysis for the symptom severity score. Test–retest reliability was confirmed for the six-item symptom severity (ICC, 0.85, number of nighttime awakenings (ICC, 0.82, and rescue medication (ICC, 0.68 scores.

    Full Text Available The chronic obstructive pulmonary disease (COPD Assessment Test (CAT, which was developed to measure the health status of patients with COPD, was applied to patients with interstitial lung disease, aiming to examine the CAT as a predictor of outcome. Over a follow-up period of more than one year, 101 consecutive patients with interstitial lung disease were evaluated by the CAT. The CAT scores of 40 in total were categorized into four subsets according to the severity. Patients with higher (more severe scores exhibited lower forced vital capacity and lung diffusion capacity for carbon monoxide. The survival rate was significantly lower in patients with higher scores (log-rank test, P = 0.0002, and the hazard ratios for death of the higher scores and lower lung diffusion capacity for carbon monoxide were independently significant. These findings suggest that CAT can indicate the risk of mortality in patients with interstitial lung disease.

    Full Text Available Abstract Background The aim of this study was to evaluate the association between health-related quality of life (HRQL and disease severity using lung function measures. Methods A survey was performed in subjects with COPD in Sweden. 168 subjects (70 women, mean age 64.3 years completed the generic HRQL questionnaire, the Short Form 36 (SF-36, the disease-specific HRQL questionnaire; the St George's Respiratory Questionnaire (SGRQ, and the utility measure, the EQ-5D. The subjects were divided into four severity groups according to FEV1 per cent of predicted normal using two clinical guidelines: GOLD and BTS. Age, gender, smoking status and socio-economic group were regarded as confounders. Results The COPD severity grades affected the SGRQ Total scores, varying from 25 to 53 (GOLD p = 0.0005 and from 25 to 45 (BTS p = 0.0023. The scores for SF-36 Physical were significantly associated with COPD severity (GOLD p = 0.0059, BTS p = 0.032. No significant association were noticed for the SF-36, Mental Component Summary scores and COPD severity. Scores for EQ-5D VAS varied from 73 to 37 (GOLD I-IV p = 0.0001 and from 73 to 50 (BTS 0-III p = 0.0007. The SGRQ Total score was significant between age groups (p = 0.0047. No significant differences in HRQL with regard to gender, smoking status or socio-economic group were noticed. Conclusion The results show that HRQL in COPD deteriorates with disease severity and with age. These data show a relationship between HRQL and disease severity obtained by lung function.

  19. Hypoxemia in patients with COPD: cause, effects, and disease progression.

    2012-02-01

    Chronic obstructive pulmonary disease (COPD) is a leading cause of death and disability internationally. Alveolar hypoxia and consequent hypoxemia increase in prevalence as disease severity increases. Ventilation\\/perfusion mismatch resulting from progressive airflow limitation and emphysema is the key driver of this hypoxia, which may be exacerbated by sleep and exercise. Uncorrected chronic hypoxemia is associated with the development of adverse sequelae of COPD, including pulmonary hypertension, secondary polycythemia, systemic inflammation, and skeletal muscle dysfunction. A combination of these factors leads to diminished quality of life, reduced exercise tolerance, increased risk of cardiovascular morbidity, and greater risk of death. Concomitant sleep-disordered breathing may place a small but significant subset of COPD patients at increased risk of these complications. Long-term oxygen therapy has been shown to improve pulmonary hemodynamics, reduce erythrocytosis, and improve survival in selected patients with severe hypoxemic respiratory failure. However, the optimal treatment for patients with exertional oxyhemoglobin desaturation, isolated nocturnal hypoxemia, or mild-to-moderate resting daytime hypoxemia remains uncertain.

    Background : Chronic obstructive pulmonary disease (COPD) is a largely underdiagnosed disease including several phenotypes. In this report, the design of a study intending to evaluate the pathophysiological mechanism in COPD in relation to the specific phenotypes non-rapid and rapid decline in lung function is described together with the recruitment process of the study population derived from a population based study. Method : The OLIN COPD study includes a population-based COPD cohort and referents without COPD identified in 2002-04 ( n  = 1986), and thereafter followed annually since 2005. Lung function decline was estimated from baseline in 2002-2004 to 2010 (first recruitment phase) or to 2012/2013 (second recruitment phase). Individuals who met the predefined criteria for the following four groups were identified; group A) COPD grade 2-3 with rapid decline in FEV 1 and group B) COPD grade 2-3 without rapid decline in FEV 1 (≥60 and ≤30 ml/year, respectively), group C) ever-smokers, and group D) non-smokers with normal lung function. Groups A-C included ever-smokers with >10 pack years. The intention was to recruit 15 subjects in each of the groups A-D. Results : From the database groups A-D were identified; group A n  = 37, group B n  = 29, group C n  = 41, and group D n  = 55. Fifteen subjects were recruited from groups C and D, while this goal was not reached in the groups A ( n  = 12) and B ( n  = 10). The most common reasons for excluding individuals identified as A or B were comorbidities contraindicating bronchoscopy, or inflammatory diseases/immune suppressive medication expected to affect the outcome. Conclusion : The study is expected to generate important results regarding pathophysiological mechanisms associated with rate of decline in lung function among subjects with COPD and the in-detail described recruitment process, including reasons for non-participation, is a strength when interpreting the results in forthcoming studies.

    Pneumonia is considered an independent entity in chronic obstructive pulmonary disease (COPD), to be distinguished from an infectious exacerbation of COPD. The aim of this study was to analyze the clinical characteristics and progress of the exacerbation of COPD (ECOPD) compared to pneumonia in COPD (PCOPD) patients requiring hospitalization. Prospective, longitudinal, observational cohort study including 124 COPD patients requiring hospital admission for lower respiratory tract infection. Patients were categorized according to presence of ECOPD (n=104) or PCOPD (n=20), depending on presence of consolidation on X-ray. Demographic, clinical, laboratory, microbiological and progress variables were collected. Patients with ECOPD showed more severe respiratory disease according to the degree of obstruction (P<.01) and need for oxygen therapy (P<.05). PCOPD patients showed increased presence of fever (P<.05), lower blood pressure (P<.001), more laboratory abnormalities (P<.05; leukocytosis, elevated CRP, low serum albumin) and increased presence of crepitus (P<.01). Microbiological diagnosis was achieved in 30.8% of cases of ECOPD and 35% of PCOPD; sputum culture yielded the highest percentage of positive results, predominantly Pseudomonas aeruginosa. Regarding the progress of the episode, no differences were found in hospital stay, need for ICU or mechanical ventilation. Our data confirm clinical and analytical differences between ECOPD and PCOPD in patients who require hospital admission, while there were no differences in subsequent progress.

    Chronic obstructive pulmonary disease (COPD) imposes a costly burden on healthcare. Pulmonary rehabilitation (PR) is the best practice to better manage COPD to improve patient outcomes and reduce acute hospital care utilization. To evaluate the impact of a once-weekly, eight-week multidisciplinary PR program as an integral part of the COPD chronic disease management (CDM) Program at Kyabram District Health Services. The study compared two cohorts of COPD patients: CDM-PR Cohort (4-8 weeks) and Opt-out Cohort (0-3 weeks) between February 2006 and March 2007. The CDM-PR Program involved multidisciplinary patient education and group exercise training. Nonparametric statistical tests were used to compare acute hospital care utilization 12 months before and after the introduction of CDM-PR. The number of patients involved in the CDM-PR Cohort was 29 (n = 29), and that in the Opt-out Cohort was 24 (n = 24). The CDM-PR Cohort showed significant reductions in cumulative acute hospital care utilization indicators (95% emergency department presentations, 95% inpatient admissions, 99% length of stay; effect sizes = 0.62-0.66, P 0.05). Total costs associated with the hospital care utilization decreased from $130,000 to $7,500 for the CDM-PR Cohort and increased from $77,700 to $101,200 for the Opt-out Cohort. Participation in the CDM-PR for COPD patients can significantly reduce acute hospital care utilization and associated costs in a small rural health service.

    In asthma and chronic obstructive pulmonary disease (COPD), mucins display disease-related alterations caused by airway mucus obstruction. MUC5AC, MUC5B and MUC8 are known as the major secretory mucins in human airway epithelial cells. Analysis of mucin genes has identified the presence of several features with a variable number of tandem repeats (VNTR; minisatellites) in the central region of each mucin. In our previous study, six minisatellites in the region of the MUC8 gene were identified, and the MUC8-MS5 minisatellite showed the highest heterozygosity among them. In this study, we evaluated the relationship between MUC8-MS5 and susceptibility to asthma and COPD. A case-control study was performed with 229 controls, 123 COPD cases and 77 asthma cases. A significant association (OR 3.96) between short alleles (2/2 repeats) and the occurrence of COPD was observed [95% confidence interval (CI) 1.32-11.88; p = 0.008]. Hence, the increased frequency of 2/2 homo-short alleles were also found in asthma cases (3.11; CI 0.88-11.05; p = 0.066), though this association was not statistically significant. These results revealed a genetic association between MUC8 and COPD, and that the specific short minisatellite alleles (2/2) of MUC8-MS5 may be a risk factor for COPD.

To measure COPD prevalence and socioeconomic and lifestyle determinants among ≥40 years Bangladeshi adults. In a cross-sectional study, we measured lung function of 3744 randomly selected adults ≥40 years from rural and urban areas in Bangladesh, using a handheld spirometer. COPD was defined according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria as post-bronchodilator ratio of Forced Expiratory Volume in 1st second (FEV1) to Forced Vital Capacity (FVC) COPD was also assessed by the lower limit of normal (LLN) threshold defined as lower fifth percentile for the predicted FEV1/FVC. The prevalence of COPD was 13.5% by GOLD criteria and 10.3% by LLN criteria. Prevalence of COPD was higher among rural than urban residents and in males than females. More than half of the COPD cases were stage II COPD by both criteria. Milder cases (Stages I and II) were over estimated by the GOLD fixed criteria, but more severe cases (Stages III and IV) were similarly classified. In multiple logistic regression analysis, older age, male sex, illiteracy, underweight, history of smoking (both current and former), history of asthma and solid fuel use were significant predictors of COPD. COPD is a highly prevalent and grossly underdiagnosed public health problem in Bangladeshi adults aged 40 years or older. Illiteracy, smoking and biomass fuel burning are modifiable determinants of COPD.

    In assigning patients with chronic obstructive pulmonary disease (COPD) to subgroups according to the updated guidelines of the Global Initiative for Chronic Obstructive Lung Disease, discrepancies have been noted between the COPD assessment test (CAT) criteria and modified Medical Research Council (mMRC) criteria. We investigated the determinants of symptom and risk groups and sought to identify a better CAT criterion. This retrospective study included COPD patients seen between June 20, 2012, and December 5, 2012. The CAT score that can accurately predict an mMRC grade ≥ 2 versus COPD patients, the percentages of patients classified into subgroups A, B, C, and D were 24.5%, 47.2%, 4.2%, and 24.1% based on CAT criteria and 49.3%, 22.4%, 8.9%, and 19.4% based on mMRC criteria, respectively. More than 90% of the patients who met the mMRC criteria for the 'more symptoms group' also met the CAT criteria. AUROC and CART analyses suggested that a CAT score ≥ 15 predicted an mMRC grade ≥ 2 more accurately than the current CAT score criterion. During follow-up, patients with CAT scores of 10 to 14 did not have a different risk of exacerbation versus those with CAT scores COPD patients.

    This study aimed at investigating the capability of sagittal-lung computed tomography (CT) measurements in differentiating chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap syndrome (ACOS). Clinical and high-resolution CT of 229 patients including 123 pure COPD patients and 106 ACOS patients were included. Sagittal-lung CT measurements in terms of bilateral lung height (LH), anterior-posterior lung diameter (APLD), diaphragm height (DH), and anterior sterno-diaphragmatic angle (ASDA), as well as inter-pulmonary septum length (IPSL) on axial images were measured both before and after bronchodilator (BD) administration. Comparisons of clinical characteristics and CT measurements between patient groups were performed. All pre-BD quantitative sagittal features measuring diaphragm flattening and hyperinflation were not significantly different between patients with COPD and patients with ACOS (P values all >0.05). Following BD administration, the ACOS patients exhibited lower left LH, bilateral APLD, and bilateral ASDA, but higher right DH, compared to pure COPD patients (P values all <0.05). Right LH, left DH and IPSL were not significantly different between patient groups. Besides, variations of all sagittal-lung CT measurements were significantly larger in patients with ACOS than in patients with pure COPD (P values all <0.001) and showed high performance in differentiating these two kinds of patient, with diagnostic sensitivities ranging from 76.4 to 97.2%, specificities ranging from 86.2 to 100.0%, and accuracies ranging from 80.9 to 90.7%. Sagittal-lung CT measurements allow for differentiating patients with ACOS from those with pure COPD. The ACOS patients had larger post-BD variations of sagittal-lung CT measurements than patients with pure COPD.

    Noncompliance with healthcare undoubtedly has a strong influence on the high prevalence of uncontrolled obstructive diseases. The aim of our study was to evaluate the quality of medical conduct in patients with asthma or chronic obstructive lung diseases (COPD), with encompassed two-levelled system of health care. A survey of general practitioners (GP), allergists and pulmonologists practicing in Poland was performed between September and December 2016. The basic survey included the data concerning the number of treated patients, the course of the visits, treatment regimens and whether the patients follow the instructions of the physician. The specialist survey recorded the details of the specialist visits, their frequency and character, an evaluation of the pharmacological and non-pharmacological therapies and an evaluation of the GP's actions. The basic questionnaire was completed by 807 doctors with an average of 21 ± 9.85 years of medical experience. Most of the interviewed individuals were GPs (56%), followed by pulmonologists (28%) and allergists (16%). The GP reported 47 cases/month with obstructive pulmonary conditions, including 48.94% asthma and 51.06% COPD patients. They diagnosed three new asthma and COPD patients per month. The allergists treated patients with asthma (105 patients/ month), with 19 newly-diagnosed patients/month. The pulmonologists treated fewer asthma cases than COPD: 71 and 98 patients respectively. They reported 14 patients/month of newly-diagnosed COPD cases. The patients took inhaled glucocorticoids and long-acting b adrenoceptor agonists in separate inhalers. The most frequently-used device was a disc. In opinion of the specialists, half of the therapies initiated recently by GPs for patients with asthma and COPD required modifications. There is a disparity between the true state of medical care of asthma and COPD patients and globally-accepted standards.

    This study aimed to determine the frequency and sociodemographic/clinical correlates of insomnia in Chinese patients aged ≥60 years suffering from chronic obstructive pulmonary disease (COPD). In this case-control study of 142 outpatients with COPD and 218 sex- and age-matched control subjects, COPD patients were recruited from a prospective study sample hospitalized in Hong Kong for acute COPD exacerbation (≥2 major COPD symptoms or >1 major+minor COPD symptoms for ≥2 consecutive days). Controls were recruited from social centres in Hong Kong. Activity of daily living was assessed with the Instrumental Activities of Daily Living Scale, life events were evaluated using the Life Event Scale, depressive symptoms were ascertained with the Geriatric Depression Scale, and quality of life was measured using the Medical Outcomes Study Short Form-12. Early, middle and late insomnia were measured using items 4, 5 and 6 of the Hamilton Rating Scale for Depression. The frequency of ≥1 type of insomnia was 47.2% in patients and 25.7% in controls; frequencies of early, middle and late insomnia in patients were 24.6%, 31.0%, and 26.1%, respectively, compared to 14.7%, 14.7% and 11.9% in controls. Group differences were non-significant after controlling for relevant covariates. However, in multiple logistic regression analysis, more physical illnesses (p = 0.02, OR = 1.3, 95% CI = 1.1-1.7) and more severe depressive symptoms (p = 0.009, OR = 1.1, 95% CI = 1.03-1.3) were independently associated with any type of insomnia in COPD patients, accounting for 21.3% of the variance. A significant proportion of older adult Chinese COPD patients suffer from insomnia that warrants more attention in clinical practice.

    Chronic obstructive pulmonary disease (COPD) is a highly prevalent disease, characterised by poorly reversible, obstructive airflow limitation. Alongside other comorbidities, COPD is associated with increased morbidity and mortality resulting from cardiovascular disease - mainly heart failure and ischemic heart disease. Both diseases share an important risk factor, namely, smoking. About 50% of COPD patients are active cigarette smokers. Bronchodilation is the cornerstone of pharmaceutical treatment for COPD symptoms, and half of all COPD patients use long-acting bronchodilating agents. Discussion about these agents is currently focusing on the association with overall mortality and morbidity in COPD patients, of cardiovascular origin in particular. Bronchodilation diminishes the hyperinflated state of the lung and facilitates the pulmonary deposition of cigarette smoke by deeper inhalation into the smaller airways. Smaller particles, as in smoke, tend to penetrate and depose more in these small airways. In addition, bronchodilation indeed increases carbon monoxide uptake in the lungs, an important gaseous compound of cigarette smoke. Since the number of cigarettes smoked is positively correlated to mortality from cardiac events, we therefore hypothesise that chronic bronchodilation increases cardiovascular disease and mortality in COPD patients who continue smoking by increasing pulmonary retention of pathogenic smoke constituents. Indeed, a recent meta-analysis is suggestive that long-acting anticholinergics might increase cardiovascular disease if patients exceed a certain number of cigarettes smoked. To demonstrate the fundamental mechanism of this pathogenic interaction we will perform a randomised placebo-controlled cross-over trial to investigate the effect of maximum bronchodilation on the retention of cigarette smoke constituents. In 40 moderate to severe COPD patients we measure the inhaled and exhaled amount of tar and nicotine, as well during maximum

    We aimed to describe the differences and similarities between patients with chronic obstructive airway disease classified on the basis of classical diagnostic labels (asthma, chronic obstructive pulmonary disease (COPD), or asthma-COPD overlap (ACOS)) or according to the underlying inflammatory pattern (Th-2 signature, either Th-2-high or Th-2-low).We performed a cross-sectional study of patients aged ≥40 years and with a post-bronchodilator forced expiratory volume in 1 s to forced vital capacity ratio ≤0.7 with a previous diagnosis of asthma (non-smoking asthmatics (NSA)), COPD or ACOS, the latter including both smoking asthmatics (SA) and patients with eosinophilic COPD (COPD-e). Clinical, functional and inflammatory parameters (blood eosinophil count, IgE and exhaled nitric oxide fraction ( F eNO )) were compared between groups. Th-2 signature was defined by a blood eosinophil count ≥300 cells·μL -1 and/or a sputum eosinophil count ≥3%.Overall, 292 patients were included in the study: 89 with COPD, 94 NSA and 109 with ACOS (44 SA and 65 with COPD-e). No differences in symptoms or exacerbation rate were found between the three groups. With regards the underlying inflammatory pattern, 94 patients (32.2%) were characterised as Th-2-high and 198 (67.8%) as Th-2-low. The Th-2 signature was found in 49% of NSA, 3.3% of patients with COPD, 30% of SA and 49.3% of patients with COPD-e. This classification yielded significant differences in demographic, functional and inflammatory characteristics.We conclude that a classification based upon the inflammatory profile, irrespective of the taxonomy, provides a more clear distinction of patients with chronic obstructive airway disease.

    Full Text Available Abstract Background A key strategy in improving care for people with chronic obstructive pulmonary disease (COPD is the provision of pulmonary rehabilitation programmes. Pulmonary rehabilitation programmes have been successful in improving patients' sense of dyspnoea and Health Related Quality of Life. However, the effectiveness of structured education pulmonary rehabilitation programmes delivered at the level of the general practice on the health status of people with COPD remains uncertain and there is a need for a robust and fair assessment of this. The PRINCE study will evaluate the effectiveness of a Structured Education Pulmonary Rehabilitation Programme (SEPRP, delivered at the level of the general practice, on the health status of people with COPD. Methods/Design The PRINCE Trial is a two-armed, single blind cluster randomised trial conducted in the primary care setting in Ireland. Randomisation to control and intervention is at the level of the General Practice. Participants in the intervention arm will receive a SEPRP and those allocated to the control arm will receive usual care. Delivery of the SEPRP will be by a practice nurse and physiotherapist in the General Practice (GP site. The primary outcome measure of the study will be health status as measured by the Chronic Respiratory Questionnaire (CRQ. Blinded outcome assessment will be undertaken at baseline and at twelve-fourteen weeks after completion of the programme. A comparison of outcomes between the intervention and control sites will be made to examine if differences exist and, if so, to what extent between control and experimental groups. Sample size calculations estimate that 32 practices with a minimum of 10 participants per practice are required, in total, to be randomised to control and intervention arms for power of at least 80% with alpha levels of 0.05, to determine a clinically significant change of 0.5 units in the CRQ.

    Chronic obstructive pulmonary disease (COPD) is characterized by an abnormal inflammatory response in the lungs caused by the inhalation of noxious particles and gases. The airway epithelium has a protective function against these harmful agents by maintaining a physical barrier and by secreting defensive proteins, such as bactericidal/permeability-increasing fold-containing (BPIF) proteins, BPIFA1 and BPIFB1. However, inconsistent data regarding BPIFA1 expression in smokers and COPD patients have been reported to date. Therefore, we investigated the expression of BPIFA1 and BPIFB1 in a large cohort of never-smokers and smokers with and without COPD, both on the messenger RNA (mRNA) level in lung tissue and on the protein level in airway epithelium. Furthermore, we examined the correlation between BPIFA1 and BPIFB1 levels, goblet cell hyperplasia, and lung function measurements. BPIFA1 and BPIFB1 mRNA expressions were significantly increased in stage III–IV COPD patients compared with stage II COPD patients and subjects without COPD. In addition, protein levels in COPD patients were significantly increased in comparison with subjects without COPD. BPIFA1 and BPIFB1 levels were inversely correlated with measurements of airflow limitation and positively correlated with goblet cell hyperplasia. In addition, by the use of immunofluorescence double staining, we demonstrated the expression of BPIFB1 in goblet cells. In conclusion, we show that BPIFA1 and BPIFB1 levels are elevated in COPD patients and correlate with disease severity. PMID:29296079

    There are limited data on the epidemiology of acute respiratory failure necessitating mechanical ventilation in patients with severe chronic obstructive pulmonary disease (COPD). The prognosis of acute respiratory failure requiring invasive mechanical ventilation is believed to be grim in this population. The purpose of this study was to illustrate the epidemiologic characteristics and outcomes of patients with underlying severe COPD requiring mechanical ventilation.A retrospective study of patients admitted to a quaternary referral medical intensive care unit (ICU) between January 2008 and December 2012 with a diagnosis of severe COPD and requiring invasive mechanical ventilation for acute respiratory failure.We evaluated 670 patients with an established diagnosis of severe COPD requiring mechanical ventilation for acute respiratory failure of whom 47% were male with a mean age of 63.7 ± 12.4 years and Acute physiology and chronic health evaluation (APACHE) III score of 76.3 ± 27.2. Only seventy-nine (12%) were admitted with a COPD exacerbation, 27(4%) had acute respiratory distress syndrome (ARDS), 78 (12%) had pneumonia, 78 (12%) had sepsis, and 312 (47%) had other causes of respiratory failure, including pulmonary embolism, pneumothorax, etc. Eighteen percent of the patients received a trial of noninvasive positive pressure ventilation. The median duration of mechanical ventilation was 3 days (interquartile range IQR 2-7); the median duration for ICU length of stay (LOS) was 5 (IQR 2-9) days and the median duration of hospital LOS was 12 (IQR 7-22) days. The overall ICU mortality was 25%. Patients with COPD exacerbation had a shorter median duration of mechanical ventilation (2 vs 4 days; P = .04), ICU (3 vs 5 days; P = .01), and hospital stay (10 vs 13 days; P = .01).

    There is insufficient evidence of the cost-effectiveness of Chronic Obstructive Pulmonary Disease (COPD) Disease Management (COPD-DM) programs. The aim of this review is to evaluate the economic impact of COPD-DM programs and investigate the relation between the impact on healthcare costs and health outcomes. We also investigated the impact of patient-, intervention, and study-characteristics. We conducted a systematic literature review to identify cost-effectiveness studies of COPD-DM. Where feasible, results were pooled using random-effects meta-analysis and explorative subgroup analyses were performed. Sixteen papers describing 11 studies were included (7 randomized control trials (RCT), 2 pre-post, 2 case-control). Meta-analysis showed that COPD-DM led to hospitalization savings of €1060 (95% CI: €2040 to €80) per patient per year and savings in total healthcare utilization of €898 (95% CI: €1566 to €231) (excl. operating costs). In these health economic studies small but positive results on health outcomes were found, such as the St Georges Respiratory Questionnaire (SGRQ) score, which decreased with 1.7 points (95% CI: 0.5-2.9). There was great variability in DM interventions-, study- and patient-characteristics. There were indications that DM showed greater savings in studies with: severe COPD patients, patients with a history of exacerbations, RCT study design, high methodological quality, few different professions involved in the program, and study setting outside Europe. COPD-DM programs were found to have favourable effects on both health outcomes and costs, but there is considerable heterogeneity depending on patient-, intervention-, and study-characteristics.

    Singing is a complex physical activity dependent on the use of the lungs for air supply to regulate airflow and create large lung volumes. In singing, exhalation is active and requires active diaphragm contraction and good posture. Chronic obstructive pulmonary disease (COPD) is a progressive, chronic lung disease characterised by airflow obstruction. Singing is an activity with potential to improve health outcomes in people with COPD. To determine the effect of singing on health-related quality of life and dyspnoea in people with COPD. We identified trials from the Cochrane Airways Specialised Register, ClinicalTrials.gov, the World Health Organization trials portal and PEDro, from their inception to August 2017. We also reviewed reference lists of all primary studies and review articles for additional references. We included randomised controlled trials in people with stable COPD, in which structured supervised singing training of at least four sessions over four weeks' total duration was performed. The singing could be performed individually or as part of a group (choir) facilitated by a singing leader. Studies were included if they compared: 1) singing versus no intervention (usual care) or another control intervention; or 2) singing plus pulmonary rehabilitation versus pulmonary rehabilitation alone. Two review authors independently screened and selected trials for inclusion, extracted outcome data and assessed risk of bias. We contacted authors of trials for missing data. We calculated mean differences (MDs) using a random-effects model. We were only able to analyse data for the comparison of singing versus no intervention or a control group. Three studies (a total of 112 participants) were included. All studies randomised participants to a singing group or a control group. The comparison groups included a film workshop, handcraft work, and no intervention. The frequency of the singing intervention in the studies ranged from 1 to 2 times a week over a 6 to 24

A retrospective, population-based cohort study design is applied, using administrative data. After eliminating differences in observable characteristics between the DMP and the control group with entropy balancing, difference-in-difference estimators were computed to account for time-invariant unobservable heterogeneity. 215,104 individuals were included into the analysis of whom 25,269 were enrolled in the DMP. DMP patients had a reduced mortality hazard ratio (0.89, 95%CI: 0.84-0.94) but incurred excess costs of €553 per year. DMP enrolees reveal higher healthcare utilisation with larger shares of individuals being hospitalised (3.14%), consulting an outpatient clinic due to exacerbations (11.13%) and pharmaceutical prescriptions (2.78). However, average length of hospitalisation due to COPD fell by 0.49 days, adherence to medication guidelines as well as indicators for morbidity improved. The German COPD DMP achieved significant improvements in mortality, morbidity and process quality, but at higher costs. Given the low ICER per life year gained, DMP COPD may constitute a cost-effective option to promote COPD population health. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    GIRD COPD Biobank is a multicenter observational study blood-based database with local characteristics, in order to investigate the causes, risk factors, pathogenesis, prevalence patterns and trends of COPD and promote new pathogenic insights in China. We enrolled 855 clinically COPD patients and 660 controls with normal lung function. Extensive data collection has been undertaken with questionnaires, clinical measurements, and collection and storage of blood specimens, following Standard Operating Procedures (SOP). All surveys had similar quality controls, supervisions, and training of the investigator team. Since September 2010, a total of 1515 subjects (1116 [73.7%] males; 855 [56.4%] diagnosed with COPD) were enrolled. Analyses of the design and interim results of the GIRD COPD Biobank Study identified patients with COPD were older, lower educational level, a longer history of pack-year smoking, less in kitchen fan usage, X-ray exposure, and history of disease (P < 0.01 for all); Most of the COPD subjects belonged to moderately severe or worse, stratified according to Global Lung Function Initiative (GLI); COPD patients had relatively more co-morbidities than controls; Environmental hazard exposures might be the main contributors to the reported respiratory symptoms; Cold air, haze, and influenza acted the top three factors to induce respiratory symptoms in both COPD cases and controls. The GIRD COPD Biobank Study has the potential to provide substantial novel insights into the genetics, biomarkers, environmental and lifestyle aspects of COPD. It is expected to provide new insights for pathogenesis and the long-term progression of COPD.

    Chronic obstructive pulmonary disease (COPD) and particularly emphysema are characterized by stiffness of the aorta, due in part to accelerated elastin degradation in the lungs and aorta. Stiffness of the pulmonary arteries (PAs) may also be increased in COPD and emphysema, but data are lacking. We assessed PA stiffness using MRI in patients with COPD and related these measurements to COPD severity and percent emphysema. The Multi-Ethnic Study of Atherosclerosis (MESA) COPD Study recruited 290 participants, age 50-79 years with 10 or more packyears and free of clinical cardiovascular disease. COPD severity were defined on postbronchodilator spirometry by ATS/ERS criteria. Percent emphysema was defined as the percentage of regions of the lung COPD compared with controls (P = 0.002) and was inversely correlated with COPD severity (P = 0.004). PA strain was inversely associated to percent emphysema (P = 0.01). PA strain was also markedly correlated with right ventricular diastolic dysfunction measured by E/A ratios in the fully adjusted mix models (P = 0.02). PA strain is reduced in COPD, related in part to percent emphysema on CT scan, which may have implications for pulmonary small vessel flow and right ventricular function. 2 Technical Efficacy: Stage 1 J.

    During the last decade, many articles have been published, including reviews on fractional exhaled nitric oxide (FeNO) use and utility in clinical practice and for monitoring and identifying eosinophilic airway inflammation, especially in asthma, and evaluating corticosteroid responsiveness. However, the exact role of FeNO in patients with chronic obstructive pulmonary disease (COPD) and its ability to distinguish patients with COPD and those having concomitant asthma, that is, asthma-COPD overlap (ACO) is still unclear and needs to be defined. Due to the broad topics of FeNO in chronic airway disease, we undertook a scoping review. The present article describes the protocol of a scoping review of peer-reviewed published literature specific to FeNO in COPD/ACO over the last decade. We used Joanna Briggs Institute Reviewers' Manual scoping review methodology as well as Levac et al 's and Arksey et al 's framework as guides. We searched a variety of databases, including Medline, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, Web of Science, and BioSciences Information Service (BIOSIS) on 29 June 2016. Additional studies will be recognised by exploring the reference list of identified eligible studies. Screening of eligible studies will be independently performed by two reviewers and any disagreement will be solved by the third reviewer. We will analyse the gathered data from article bibliographies and abstracts. To investigate the body of published studies regarding the role of FeNO in patients with COPD and its usefulness in the clinical setting, a scoping review can be used as a modern and pioneer model, which does not need ethics approval. By this review, new insights for conducting new research specific to FeNO in COPD/ACO population will emerge. The results of this study will be reported in the scientific meetings and conferences, which aim to provide information to the clinicians, primary care providers and basic

    BACKGROUND: The purpose of this study was to assess to what extent symptoms and signs of bacterial infection are present and evaluated in patients admitted to the hospital for exacerbation of chronic obstructive pulmonary disease (COPD) in relation to initiation of antibiotic treatment. METHODS......: All adult patients (>18 years of age) discharged from a department of internal medicine in Copenhagen in 1997 with a diagnosis of exacerbation of COPD were included in our study and their reports were retrospectively reviewed. Gender, age, number of admissions and length of hospital stay, use...... was the initial antibiotic of choice. The median hospital stay was 6 days for the entire group of patients. CONCLUSION: These data suggest that, in patients with acute exacerbation of COPD, a relatively high number of patients with only weak symptoms or signs of bacterial infection are treated with antibiotics....

    Patients with COPD often require repeated emergency department visits and hospitalizations for COPD exacerbations. Such readmissions increase health-care costs and expose COPD patients to the added risks of nosocomial infections and increased mortality. To determine whether a respiratory therapist (RT) disease management program could reduce re-hospitalization and emergency department visits, a prospective, single-center, unblinded, randomized trial was performed. We enrolled 428 subjects (214 intervention, 214 control). The primary outcome (combined non-hospitalized emergency department visits and hospital readmissions for a COPD exacerbation during the 6-month follow-up) was similar for the study groups (91 vs 159, P = .08). When the 2 components of the primary end point were analyzed individually, the percentage of subjects with non-hospitalized emergency department visits for COPD exacerbations was similar between groups (15.0% vs 15.9%, P = .79). Readmission for a COPD exacerbation was significantly lower in the intervention group (20.1% vs 28.5%, P = .042). The median (interquartile range) duration of hospitalization for a COPD exacerbation was less for the intervention group (5 [3-11] d vs 8 [4-18.5] d, P = .045). In-patient hospital days (306 d vs 523 d, P = .02) and ICU days (17 d vs 53 d, P = .02) due to COPD exacerbations were significantly less for the intervention group. Mortality was similar for both groups (1.4% vs 0.9%, P > .99). Our RT disease management program was associated with less readmission, fewer ICU days, and shorter hospital stays due to COPD exacerbations. Further studies are needed to determine the optimal utilization of RT disease management teams for patients with COPD to optimize outcomes and prevent return hospital visits.

    The risk factors for acute episodes of respiratory disease in current and former smokers who do not have COPD are unknown. Eight thousand two hundred forty-six non-Hispanic white and black current and former smokers in the Genetic Epidemiology of COPD (COPDGene) cohort had longitudinal follow-up (LFU) every 6 months to determine acute respiratory episodes requiring antibiotics or systemic corticosteroids, an ED visit, or hospitalization. Negative binomial regression was used to determine the factors associated with acute respiratory episodes. A Cox proportional hazards model was used to determine adjusted hazard ratios (HRs) for time to first episode and an acute episode of respiratory disease risk score. At enrollment, 4,442 subjects did not have COPD, 658 had mild COPD, and 3,146 had moderate or worse COPD. Nine thousand three hundred three acute episodes of respiratory disease and 2,707 hospitalizations were reported in LFU (3,044 acute episodes of respiratory disease and 827 hospitalizations in those without COPD). Major predictors included acute episodes of respiratory disease in year prior to enrollment (HR, 1.20; 95% CI, 1.15-1.24 per exacerbation), airflow obstruction (HR, 0.94; 95% CI, 0.91-0.96 per 10% change in % predicted FEV1), and poor health-related quality of life (HR, 1.07; 95% CI, 1.06-1.08 for each 4-unit increase in St. George's Respiratory Questionnaire score). Risks were similar for those with and without COPD. Although acute episode of respiratory disease rates are higher in subjects with COPD, risk factors are similar, and at a population level, there are more episodes in smokers without COPD.

    Pim-3 belongs to the PIM kinase family and plays an important role in promoting inflammation, which is essential in the pathogenesis of Chronic Obstructive Pulmonary Disease (COPD). Immunohistochemistry (IHC), western blot, and RT-PCR analyses were performed to assess the expression of Pim-3 in both COPD and healthy lung tissue samples. SMA (Smooth Muscle Actin) and Cyclin D1 expression were detected by IHC. We also constructed animal models for the control, COPD, and Pim-3 inhibition groups, in order to analyze the effects of Pim-3 inhibition on COPD, and the role of Pim-3 in the p38 pathway. Compared with normal lung tissue, Pim-3 mRNA and protein were up-regulated in COPD tissue. Expression of Cyclin D1 and SMA were also up-regulated in the COPD group. In the animal model experiment, we found that suppression of Pim-3 decreased Pim-3, Cyclin D1, and SMA expression, as well as ameliorated lung damage in COPD patients. The inhibition of Pim-3 also resulted in the suppression of the p38 pathway. Our study suggests that up-regulation of Pim-3 successfully accelerated COPD development, and aggravated lung damage. The molecular mechanism of Pim-3 in COPD might be related to the p38 pathway, and is correlated with Cyclin D1 and SMA expression. Copyright © 2017 Elsevier GmbH. All rights reserved.

    BACKGROUND Chronic obstructive pulmonary disease (COPD) is a commonly diagnosed condition in people older than 50 years of age. In advanced stage of this disease, integrated care (IC) is recommended as an optimal approach. IC allows for holistic and patient-focused care carried out at the patient's home. The aim of this study was to analyze the impact of IC on costs of care and on demand for medical services among patients included in IC. MATERIAL AND METHODS The study included 154 patients diagnosed with advanced COPD. Costs of care (general, COPD, and exacerbations-related) were evaluated for 1 year, including 6-months before and after implementing IC. The analysis included assessment of the number of medical procedures of various types before and after entering IC and changes in medical services providers. RESULTS Direct medical costs of standard care in advanced COPD were 886.78 EUR per 6 months. Costs of care of all types decreased after introducing IC. Changes in COPD and exacerbation-related costs were statistically significant (p=0.012492 and p=0.017023, respectively). Patients less frequently used medical services for respiratory system and cardiovascular diseases. Similarly, the number of hospitalizations and visits to emergency medicine departments decreased (by 40.24% and 8.5%, respectively). The number of GP visits increased after introducing IC (by 7.14%). CONCLUSIONS The high costs of care in advanced COPD indicate the need for new forms of effective care. IC caused a decrease in costs and in the number of hospitalization, with a simultaneous increase in the number of GP visits.

    Full Text Available Abstract Background Approximately 210 million people are estimated to have chronic obstructive pulmonary disease [COPD] worldwide. The burden of disease is known to be high, though less is known about those of a younger age. The aim of this study was to investigate the wider personal, economic and societal burden of COPD on a cross country working-age cohort. Methods A cross-country [Brazil, China, Germany, Turkey, US, UK] cross-sectional survey methodology was utilised to answer the research questions. 2426 participants aged 45-67 recruited via a number of recruitment methods specific to each country completed the full survey. Inclusion criteria were a recalled physician diagnosis of COPD, a smoking history of > 10 pack years and the use of COPD medications in the previous 3 months prior to questioning. The survey included items from the validated Work Productivity and Activity Impairment [WPAI] scale and the EuroQoL 5 Dimension [EQ-5D] scale. Disease severity was measured using the 5-point MRC [Medical Research Council] dyspnoea scale as a surrogate measure. Results 64% had either moderate [n = 1012] or severe [n = 521] COPD, although this varied by country. 75% of the cohort reported at least one comorbid condition. Quality of life declined with severity of illness [mild, mean EQ-5D score = 0.84; moderate 0.58; severe 0.41]. The annual cost of healthcare utilisation [excluding treatment costs and diagnostic tests] per individual was estimated to be $2,364 [£1,500]. For those remaining in active employment [n: 677]: lost time from work cost the individual an average of $880 [£556] per annum and lifetime losses of $7,365 [£4,661] amounting to $596,000 [£377,000] for the cohort. 447 [~40%] of the working population had retired prematurely because of COPD incurring individual estimated lifetime income losses of $316,000 [£200,000] or a combined total of $141 m [£89.6 m]. As the mean age of retirees was 58.3 and average time since retirement

    Clinical onset of chronic obstructive pulmonary disease (COPD) is the point at which the disease is first identifiable by physicians. It is a poorly defined stage which seems to include both mild spirometric and non-spirometric disease, and could be described as early grade COPD, for practical purposes. While dyspnoea; chronic bronchitis and CT imaging evidence of emphysema and airway disease may be present very early, the lone significance of dyspnoea, the most relevant symptom in COPD in identifying these individuals, has been scarcely assessed.The Searching Clinical COPD Onset (SOON) Study was designed primarily to detect clinical, physiological and structural differences between dyspnoeic and non-dyspnoeic individuals with early grade COPD. It is hypothesised that presence of dyspnoea in early disease may identify a subtype of individuals with reduced exercise capacity, notwithstanding of their spirometry results. In addition, dyspnoeic individuals will share worse quality of life, lower physical activity, greater lung hyperinflation greater emphysema and airway thickness and reduced peripheral muscle mass than their non-dyspnoeic counterpart. SOON is a monocentric study, with a cross sectional design aimed at obtaining representative samples of current or ex-smoker-adults aged ≥45 and ≤80 years. Two hundred and forty participants will be enrolled into four strata, according to normal spirometry or mild spirometric obstruction and presence or not of dyspnoea modified Medical Research Council score ≥1. The primary outcome will be the difference between dyspnoeic and non-dyspnoeic individuals on the 6-min walk test performance, regardless of their spirometry results. To account for the confounding effect of heart failure on dyspnoea, stress echocardiography will be also performed. Secondary outcomes will include clinical (quality of life, physical activity), physiological (exercise testing) and structural characteristics (emphysema, airway disease and

    Full Text Available There is considerable variability in the susceptibility of smokers to develop chronic obstructive pulmonary disease (COPD. The only known genetic risk factor is severe deficiency of alpha(1-antitrypsin, which is present in 1-2% of individuals with COPD. We conducted a genome-wide association study (GWAS in a homogenous case-control cohort from Bergen, Norway (823 COPD cases and 810 smoking controls and evaluated the top 100 single nucleotide polymorphisms (SNPs in the family-based International COPD Genetics Network (ICGN; 1891 Caucasian individuals from 606 pedigrees study. The polymorphisms that showed replication were further evaluated in 389 subjects from the US National Emphysema Treatment Trial (NETT and 472 controls from the Normative Aging Study (NAS and then in a fourth cohort of 949 individuals from 127 extended pedigrees from the Boston Early-Onset COPD population. Logistic regression models with adjustments of covariates were used to analyze the case-control populations. Family-based association analyses were conducted for a diagnosis of COPD and lung function in the family populations. Two SNPs at the alpha-nicotinic acetylcholine receptor (CHRNA 3/5 locus were identified in the genome-wide association study. They showed unambiguous replication in the ICGN family-based analysis and in the NETT case-control analysis with combined p-values of 1.48 x 10(-10, (rs8034191 and 5.74 x 10(-10 (rs1051730. Furthermore, these SNPs were significantly associated with lung function in both the ICGN and Boston Early-Onset COPD populations. The C allele of the rs8034191 SNP was estimated to have a population attributable risk for COPD of 12.2%. The association of hedgehog interacting protein (HHIP locus on chromosome 4 was also consistently replicated, but did not reach genome-wide significance levels. Genome-wide significant association of the HHIP locus with lung function was identified in the Framingham Heart study (Wilk et al., companion article

Disease severity was associated with bone and muscle adverse outcomes, while age ≥ 63.5 years old, low lean mass, higher iPTH, and a T-score below - 2.5 were all associated with higher risk of fracture. Osteoporosis is frequently neglected in patients with COPD. We aimed at evaluating the rate of osteoporosis, fractures, and low lean mass in patients with COPD. Ninety-nine patients with COPD (53 women, 64.5 ± 9.6 years old, and 46 men, 65.9 ± 8.0 years old) underwent bone densitometry (DXA) with body composition analyses. Healthy individuals (N = 57) not exposed to tobacco matched by sex, age, and body mass index (BMI) were used as controls. Spirometry, routine laboratory workout, and conventional thoracolumbar radiography surveying for vertebral deformities were performed in all patients. Osteoporosis was found in 40.4% of the COPD patients against only 13.0% of the healthy controls (p = 0.001). Vertebral fractures were seen in 24.4% of the men and 22.0% of the women with COPD. Disease severity (GOLD 3 and 4) was significantly associated with higher risk of vitamin D deficiency (p = 0.032), lower BMD (both men and women at all sites), higher frequency of osteoporosis (in women at all sites), lower skeletal mass index, and higher rate of low lean mass (in both men and women) than healthy controls and COPD patients with milder disease (GOLD 1 and 2). Age was a main predictor of vertebral fractures (OR = 1.164 (1.078-9.297); p lean mass were associated with FEV 1% lean mass, high iPTH, and low bone mass were all significantly associated with fractures in COPD patients.

    Many unmet needs still remain in the assessment and treatment of patients with chronic obstructive pulmonary disease (COPD), particularly in relation to its under- and misdiagnosis, which lead to under- and mistreatment. This paucity of knowledge about the importance and presence of COPD, as well as its treatment, is seen with patients and carers as well as healthcare providers. This review considers the areas of key educational need, including the clinical characteristics of COPD, factors contributing to the disease, effective diagnosis, and clinical management of patients, and the implementation of treatment guidelines. As COPD remains the third most frequent cause of death in the world, we must continue to expand the scope and reach of our efforts to improve outcomes in this debilitating disease. Copyright © 2018.

    Chronic obstructive pulmonary disease (COPD) is the chronic respiratory disease with the most important burden on public health in terms of morbidity, mortality and health costs. For patients, COPD is a major source of disability because of dyspnea, restriction in daily activities, exacerbation, risk of chronic respiratory failure and extra-respiratory systemic organ disorders. The previous French Language Respiratory Society (SPLF) guidelines on COPD exacerbations were published in 2003. Using the GRADE methodology, the present document reviews the current knowledge on COPD exacerbation through 4 specific outlines: (1) epidemiology, (2) clinical evaluation, (3) therapeutic management and (4) prevention. Specific aspects of outpatients and inpatients care are discussed, especially regarding assessment of exacerbation severity and pharmacological approach. Copyright © 2017 SPLF.

    There has been renewal of interest in the use of prophylactic antibiotics to reduce the frequency of exacerbations and improve quality of life in chronic obstructive pulmonary disease (COPD). To determine whether or not regular treatment of COPD patients with prophylactic antibiotics reduces exacerbations or affects quality of life. We searched the Cochrane Airways Group Trials Register and bibliographies of relevant studies. The latest literature search was August 2013. Randomised controlled trials (RCTs) that compared prophylactic antibiotics with placebo in patients with COPD. We used the standard methods of The Cochrane Collaboration. Data were extracted and analysed by two independent review authors. Seven RCTs involving 3170 patients were included in this systematic review. All studies were published between 2001 and 2011. Five studies were of continuous antibiotics and two studies were of intermittent antibiotic prophylaxis (termed 'pulsed' for this review). The antibiotics investigated were azithromycin, erythromycin, clarithromycin and moxifloxacin. Azithromycin, erythromycin and clarithromycin are macrolides while moxifloxacin is a fourth-generation synthetic fluoroquinolone antibacterial agent. The study duration varied from three months to 36 months and all used intention-to-treat analysis. Most of the results were of moderate quality. The risk of bias of the included studies was generally low, and we did not downgrade the quality of evidence for risk of bias.The trials recruited participants with a mean age of 66 years and with at least a moderate severity of COPD. Three trials included participants with frequent exacerbations and two trials recruited participants requiring systemic steroids or antibiotics, or both, or who were at the end stage of their disease and required oxygen.The primary outcomes for this review were the number of exacerbations and quality of life.With use of continuous prophylactic antibiotics the number of patients experiencing

    Smoking-related microvascular loss causes end-organ damage in the kidneys, heart, and brain. Basic research suggests a similar process in the lungs, but no large studies have assessed pulmonary microvascular blood flow (PMBF) in early chronic lung disease. To investigate whether PMBF is reduced in mild as well as more severe chronic obstructive pulmonary disease (COPD) and emphysema. PMBF was measured using gadolinium-enhanced magnetic resonance imaging (MRI) among smokers with COPD and control subjects age 50 to 79 years without clinical cardiovascular disease. COPD severity was defined by standard criteria. Emphysema on computed tomography (CT) was defined by the percentage of lung regions below -950 Hounsfield units (-950 HU) and by radiologists using a standard protocol. We adjusted for potential confounders, including smoking, oxygenation, and left ventricular cardiac output. Among 144 participants, PMBF was reduced by 30% in mild COPD, by 29% in moderate COPD, and by 52% in severe COPD (all P emphysema-950HU and radiologist-defined emphysema, particularly panlobular and centrilobular emphysema (all P ≤ 0.01). Registration of MRI and CT images revealed that PMBF was reduced in mild COPD in both nonemphysematous and emphysematous lung regions. Associations for PMBF were independent of measures of small airways disease on CT and gas trapping largely because emphysema and small airways disease occurred in different smokers. PMBF was reduced in mild COPD, including in regions of lung without frank emphysema, and may represent a distinct pathological process from small airways disease. PMBF may provide an imaging biomarker for therapeutic strategies targeting the pulmonary microvasculature.

    COPD and asthma are important chronic inflammatory disorders with a high associated morbidity. Much research has concentrated on the role of inflammatory cells, such as the neutrophil, in these diseases, but relatively little focus has been given to the endothelial tissue, through which inflammatory cells must transmigrate to reach the lung parenchyma and cause damage. There is evidence that there is an abnormal amount of endothelial tissue in COPD and asthma and that this tissue and its' progenitor cells behave in a dysfunctional manner. This article reviews the evidence of the involvement of pulmonary endothelium in COPD and asthma and potential treatment options for this.

    Early detection of COPD may reduce the future burden of the disease. We aimed to investigate whether prescreening with a COPD-6 screening device (measuring FEV 1 and FEV 6 ) facilitates early detection of COPD in primary care. In primary care, individuals at high risk of COPD (ie, age ≥35 years, relevant exposure, and at least one respiratory symptom) and no previous diagnosis of obstructive lung disease were examined with a COPD-6 screening device. In prioritized order, the criteria for proceeding to confirmatory spirometry were FEV 1 /FEV 6 COPD regardless of test result (medical doctor's [MD] decision). Based on spirometry, including bronchodilator (BD) reversibility test, individuals were classified as COPD (post-BD FEV 1 /FVC COPD-6 screening to confirmative spirometry based on the following criteria: 510 (54%) FEV 1 /FEV 6 COPD (51%), asthma (3%), and no obstructive lung disease (45%). COPD was diagnosed in 487 (16%) of the enrolled subjects in whom confirmative spirometry was performed in 69% based on FEV 1 /FEV 6 COPD-6 device showed acceptable specificity for the selection of subjects for diagnostic spirometry and is likely to be a useful alternative to current practice in primary care.

    As a coordinated research project of the International Atomic Energy Agency (IAEA), a multicentre joint study on radioaerosol lung scan using the BARC nebulizer has prospectively been carried out during 1988-1992 with the participation of 10 member countries in Asia [Bangladesh, China, India, Indonesia, Japan, Korea, Pakistan, Philippines, Singapore and Thailand]. The study was designed so that it would primarily cover chronic obstructive pulmonary disease (COPD) and the other related and common pulmonary diseases. The study also included normal controls and asymptomatic smokers. The purposes of this presentation are three fold: firstly, to document the usefulness of the nebulizer and the validity of user's protocol in imaging COPD and other lung diseases; secondly, to discuss scan features of the individual COPD and other disorders studied and thirdly, to correlate scan alterations with radiographic findings. Before proceeding with a systematic analysis of aerosol scan patterns in the disease groups, we documented normal pattern. The next step was the assessment of scan features in those who had been smoking for more than several years but had no symptoms or signs referable to airways. The lung diseases we analyzed included COPD [emphysema, chronic bronchitis, asthma and bronchiectasis], bronchial obstruction, compensatory overinflation and other common lung diseases such as lobar pneumonia, tuberculosis, interstitial fibrosis, diffuse panbronchiolitis, lung edema and primary and metastatic lung cancers. Lung embolism, inhalation bums and glue-sniffer's lung are separately discussed by Dr. Sundram of Singapore elsewhere in this book. The larger portion of this chapter is allocated to the discussion of COPD with a special effort made in sorting out differential scan features. Diagnostic criteria in individual COPD were defined for each category of disease and basic clinical symptoms and signs and pertinent laboratory data as well as radiographic manifestations are

    Full Text Available Some have suggested that chronic obstructive pulmonary disease (COPD is a disease of accelerated aging. Aging is characterized by shortening of telomeres. The relationship of telomere length to important clinical outcomes such as mortality, disease progression and cancer in COPD is unknown. Using quantitative polymerase chain reaction (qPCR, we measured telomere length of peripheral leukocytes in 4,271 subjects with mild to moderate COPD who participated in the Lung Health Study (LHS. The subjects were followed for approximately 7.5 years during which time their vital status, FEV(1 and smoking status were ascertained. Using multiple regression methods, we determined the relationship of telomere length to cancer and total mortality in these subjects. We also measured telomere length in healthy "mid-life" volunteers and patients with more severe COPD. The LHS subjects had significantly shorter telomeres than those of healthy "mid-life" volunteers (p<.001. Compared to individuals in the 4(th quartile of relative telomere length (i.e. longest telomere group, the remaining participants had significantly higher risk of cancer mortality (Hazard ratio, HR, 1.48; p = 0.0324 and total mortality (HR, 1.29; p = 0.0425. Smoking status did not make a significant difference in peripheral blood cells telomere length. In conclusion, COPD patients have short leukocyte telomeres, which are in turn associated increased risk of total and cancer mortality. Accelerated aging is of particular relevance to cancer mortality in COPD.

    The social gradient in chronic obstructive pulmonary disease (COPD) is considerable, but the influence of deprivation on common clinical risk factors such as malnutrition is unclear. This study aimed to explore the relationship between COPD disease-severity, deprivation and malnutrition. 424 outpatients with a confirmed diagnosis of COPD were routinely screened for malnutrition risk using the 'Malnutrition Universal Screening Tool' ('MUST') while attending respiratory clinics across two hospitals; a large city hospital (site A) and a smaller community hospital (site B). Deprivation was assessed for each outpatient according to their address (postcode) using the English governments' index of multiple deprivation (IMD) and related to malnutrition risk. Each postcode was attributed to both an IMD score and IMD rank, where a higher IMD score and a lower IMD ranking indicated increased deprivation. Overall prevalence of malnutrition was 22% (95% CI 18-26%; 9% medium risk, 13% high risk). It was significantly higher at site A (28% vs 17%; p = 0.004) where patients were also significantly more likely to reside in areas of more deprivation than those at site B (IMD rank: 15,510 SD 8137 vs 22,877 SD 6827; p COPD disease-severity was positively associated with malnutrition (p COPD. Consideration of deprivation is important in the identification of malnutrition and the nutritional management of patients with COPD. Crown Copyright © 2016. Published by Elsevier Ltd.

    2009-03-01

    Full Text Available Abstract Background Chronic obstructive pulmonary disease (COPD is a respiratory inflammatory condition with autoimmune features including IgG autoantibodies. In this study we analyze the complexity of the autoantibody response and reveal the nature of the antigens that are recognized by autoantibodies in COPD patients. Methods An array of 1827 gridded immunogenic peptide clones was established and screened with 17 sera of COPD patients and 60 healthy controls. Protein arrays were evaluated both by visual inspection and a recently developed computer aided image analysis technique. By this computer aided image analysis technique we computed the intensity values for each peptide clone and each serum and calculated the area under the receiver operator characteristics curve (AUC for each clone and the separation COPD sera versus control sera. Results By visual evaluation we detected 381 peptide clones that reacted with autoantibodies of COPD patients including 17 clones that reacted with more than 60% of the COPD sera and seven clones that reacted with more than 90% of the COPD sera. The comparison of COPD sera and controls by the automated image analysis system identified 212 peptide clones with informative AUC values. By in silico sequence analysis we found an enrichment of sequence motives previously associated with immunogenicity. Conclusion The identification of a rather complex humoral immune response in COPD patients supports the idea of COPD as a disease with strong autoimmune features. The identification of novel immunogenic antigens is a first step towards a better understanding of the autoimmune component of COPD.

    To validate outcomes of presently available chronic obstructive pulmonary disease (COPD) cost-effectiveness models against results of two large COPD trials-the 3-year TOwards a Revolution in COPD Health (TORCH) trial and the 4-year Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT) trial. Participating COPD modeling groups simulated the outcomes for the placebo-treated groups of the TORCH and UPLIFT trials using baseline characteristics of the trial populations as input. Groups then simulated treatment effectiveness by using relative reductions in annual decline in lung function and exacerbation frequency observed in the most intensively treated group compared with placebo as input for the models. Main outcomes were (change in) total/severe exacerbations and mortality. Furthermore, the absolute differences in total exacerbations and quality-adjusted life-years (QALYs) were used to approximate the cost per exacerbation avoided and the cost per QALY gained. Of the six participating models, three models reported higher total exacerbation rates than observed in the TORCH trial (1.13/patient-year) (models: 1.22-1.48). Four models reported higher rates than observed in the UPLIFT trial (0.85/patient-year) (models: 1.13-1.52). Two models reported higher mortality rates than in the TORCH trial (15.2%) (models: 20.0% and 30.6%) and the UPLIFT trial (16.3%) (models: 24.8% and 36.0%), whereas one model reported lower rates (9.8% and 12.1%, respectively). Simulation of treatment effectiveness showed that the absolute reduction in total exacerbations, the gain in QALYs, and the cost-effectiveness ratios did not differ from the trials, except for one model. Although most of the participating COPD cost-effectiveness models reported higher total exacerbation rates than observed in the trials, estimates of the absolute treatment effect and cost-effectiveness ratios do not seem different from the trials in most models.

    This case-control study was designed to investigate the association between adherences to the Dietary Approaches to Stop Hypertension (DASH) diet in patients with chronic obstructive pulmonary disease (COPD) in comparison to subjects without COPD. This is a case-control study. Usual dietary intake was assessed using a validated food frequency questionnaire. Lung function was evaluated with spirometry testing, and one of the researchers inquired about other respiratory symptoms, including chronic cough, sputum, and breathlessness. Adherence to the DASH dietary pattern was assessed according to the Fung method. This study was conducted at Alzahra University Hospital of Isfahan, Iran, in 2015. Eight-four patients with COPD and 80 subjects without a history of COPD participated in study. The mean age of participants was 57 years. Average smoking in the case group was about 27.5 pack-years. Spirometry tests including forced expiratory volume in 1 second (FEV 1 ), forced vital capacity (FVC), and FEV 1 /FVC were significantly lower in patients with COPD (p = 0.0001). Among COPD symptoms, cough was significantly decreased across tertiles of DASH score (p = 0.03). Significant differences were found for DASH score between patients with COPD and control subjects (19.82 + 3.63 vs 21.13 + 3.82, p = 0.02). Vitamin C, vitamin E, and dietary fiber intake were lower in patients with COPD (144.32 + 70.51 vs 166.97 + 71.88, p = 0.04, 7.49 + 3.91 vs 8.72 + 3.21, p = 0.02 and 19.34 + 7.05 vs 22.19 + 7.87, p = 0.01, respectively). We observed that adherence to a DASH dietary pattern among patients with COPD was significantly lower compared to the control group. Cough was significantly decreased by increments in adherence to a DASH dietary pattern.

    2017-10-01

    Chronic obstructive pulmonary disease (COPD) is primarily an airway condition, which mainly affects cigarette smokers and presents with shortness of breath that is progressive and poorly reversible. In COPD research, there has been a long held belief that airway disease progression is due to inflammation. Although this may be true in the airway lumen with innate immunity activated by the effect of smoke or secondary to infection, the accurate picture of inflammatory cells in the airway wall, where the pathophysiological COPD remodeling occurs, is uncertain and debatable. Areas covered: The current review provides a comprehensive literature survey of the changes in the main inflammatory cells in human COPD patients and focuses on contrarian views that affect the prevailing dogma on inflammation. The review also delves into the role of oxidative stress and inflammasomes in modulating the immune response in COPD. Further, the effects of inflammation in affecting the epithelium, fibroblasts, and airway remodeling are discussed. Expert commentary: Inflammation as a driving force for airway wall damage and remodelling in early COPD is at the very least 'oversimplified' and is likely to be misleading. This has serious implications for rational thinking about the illness, including pathogenesis and designing therapy.

One of the most common chronic diseases during EWC is chronic obstructive pulmonary disease (COPD. The definition of contraindications for use of railway employees with COPD given by Ordinance 655 is in very general terms, trying to make it easier and improve the quality of assessment of work capacity, we have developed an algorithm for the assessment of work ability among these workers. When doubt the existence of COPD should first prove that the disease exists, according to GOLD (Global Initiative for Chronic Obstructive Lung Disease guidelines, and for occupational medicine we considered important to clarify and standardize the assessment criteria for EWC, which resulting in a diagnostic algorithm for EWC. It is also important to know which type of job will worker to do. Application of a diagnostic algorithm in EWC will allow optimal assessment of disease severity in railway and other workers suffering of COPD working at the workplace with an increased risk efficacy treatment evaluation; assess compensation of functional defects and determine schedule of periodical examination.

    The association between vitamin D and clinical parameters in obstructive lung diseases (OLDs), including COPD and bronchial asthma, was previously investigated. As asthma-COPD overlap syndrome (ACOS) is a new clinical entity, the prevalence of vitamin D levels in ACOS is unknown. Our aim was to assess the levels of circulating vitamin D (25-hydroxyvitamin D [25(OH)D]) in different OLDs, including ACOS patients, and its correlation with clinical parameters. A total of 106 men and women (control, n=21; asthma, n=44; COPD, n=21; and ACOS, n=20) were involved in the study. All patients underwent detailed clinical examinations; disease control and severity was assessed by disease-specific questionnaires (COPD assessment test, asthma control test, and modified Medical Research Council); furthermore, 25(OH)D levels were measured in all patients. The 25(OH)D level was significantly lower in ACOS and COPD groups compared to asthma group (16.86±1.79 ng/mL and 14.27±1.88 ng/mL vs 25.66±1.91 ng/mL). A positive correlation was found between 25(OH)D level and forced expiratory volume in 1 second (r=0.4433; PD level showed a positive correlation in the ACOS (r=0.4761; P=0.0339) but not in the asthma group. Higher COPD assessment test total scores correlated with decreased 25(OH)D in ACOS (r=-0.4446; P=0.0495); however, this was not observed in the COPD group. Vitamin D deficiency is present in ACOS patients and circulating 25(OH)D level may affect disease control and severity.

    Abstract Purpose: Because of limited accessibility to pulmonary rehabilitation programs, patients with chronic obstructive pulmonary disease (COPD) are infrequently provided with patient education resources. To help educate patients with COPD on how to live a better life with diminished breathing capacity, we developed a novel social media resource center containing COPD respiratory therapy and education videos called "COPDFlix." A heuristic evaluation of COPDFlix was conducted as part of a larger study to determine whether the prototype was successful in adhering to formal Web site usability guidelines for older adults. A purposive sample of three experts, with expertise in Web design and health communications technology, was recruited (a) to identify usability violations and (b) to propose solutions to improve the functionality of the COPDFlix prototype. Each expert evaluated 18 heuristics in four categories of task-based criteria (i.e., interaction and navigation, information architecture, presentation design, and information design). Seventy-six subcriteria across these four categories were assessed. Quantitative ratings and qualitative comments from each expert were compiled into a single master list, noting the violated heuristic and type/location of problem(s). Sixty-one usability violations were identified across the 18 heuristics. Evaluators rated the majority of heuristic subcriteria as either a "minor hindrance" (n=32) or "no problem" (n=132). Moreover, only 2 of the 18 heuristic categories were noted as "major" violations, with mean severity scores of ≥3. Mixed-methods data analysis helped the multidisciplinary research team to categorize and prioritize usability problems and solutions, leading to 26 discrete design modifications within the COPDFlix prototype.

    Introduction Intergenerational associations in chronic obstructive pulmonary disease (COPD) have been well recognized and may result from genetic, gene environment, or exposure to life course factors. Consequently, adult offspring of parents with COPD may be at a greater risk of developing COPD. The aim of this study was to review the prevalence of co-occurrence of COPD in adult offspring with one or both parents having COPD independent of specific genetic variations. Methods In total, five databases were searched for original studies in which prevalence of COPD was reported in both offspring (children) and one or both parents. Studies were excluded if COPD was not clearly defined, COPD was linked to specific genetic variations, COPD was combined with other chronic respiratory conditions, or estimates included other first-degree relatives. Data extraction (ie, sample characteristics, prevalence of COPD, and odds ratio [OR] if reported) was completed by two independent reviewers. A meta-analysis of prevalence and OR was conducted, where possible. Results Of the 3,382 citations, 129 full texts were reviewed to include eight studies (six case–control, one cross-sectional, and one cohort) reflecting either prevalence of COPD in offspring of parents with COPD (descendent approach, n=3), which ranged from 0% to 17.3%, or prevalence of people with COPD reporting positive parental history of COPD (antecedent approach, n=5), for which the pooled prevalence was 28.6%. Offspring of people with COPD had 1.57 times greater odds (95% confidence interval =1.29–1.93; PCOPD compared with people not having a parental history of COPD. Conclusion The prevalence of COPD in adult offspring of people with COPD is greater than population-based estimates, and the ORs indicate a higher risk in this group. This offers clinicians a potential strategy for opportunistic screening, early identification, and intervention in this at-risk group. PMID:28182144

    The COPD Patient Management European Trial (COMET) investigated the efficacy and safety of a home-based COPD disease management intervention for severe COPD patients.The study was an international open-design clinical trial in COPD patients (forced expiratory volume in 1 s management intervention or to the usual management practices at the study centre. The disease management intervention included a self-management programme, home telemonitoring, care coordination and medical management. The primary end-point was the number of unplanned all-cause hospitalisation days in the intention-to-treat (ITT) population. Secondary end-points included acute care hospitalisation days, BODE (body mass index, airflow obstruction, dyspnoea and exercise) index and exacerbations. Safety end-points included adverse events and deaths.For the 157 (disease management) and 162 (usual management) patients eligible for ITT analyses, all-cause hospitalisation days per year (mean±sd) were 17.4±35.4 and 22.6±41.8, respectively (mean difference -5.3, 95% CI -13.7 to -3.1; p=0.16). The disease management group had fewer per-protocol acute care hospitalisation days per year (p=0.047), a lower BODE index (p=0.01) and a lower mortality rate (1.9% versus 14.2%; pmanagement intervention did not significantly reduce unplanned all-cause hospitalisation days, but reduced acute care hospitalisation days and mortality in severe COPD patients.

    Introduction and objective. COPD is a medical state characterized by chronically poor airflow, and typically worsens over time. Farmers have an increased risk of COPD because of being exposed to ammonia, hydrogen sulfide, inorganic dust, and organic dust. The quality of life of the ill depends on biomedical as well as psychosocial factors, the impact of which has not been a frequent subject of studies among COPD patients. The aim of the study was to indicate the factors that have negative and positive influence on the quality of life of farmers suffering from COPD. Materials and method. The study was conducted among 84 farmers treated for COPD in the Department of Pneumology, Oncology and Allergology of the Medical University in Lublin, Poland. The differences between the farmers concerned: severity of the disease, level of education and income, frequency of smoking tobacco and drinking alcohol, kinds of support they receive from their families, and the level of depression and anxiety experienced by the patients. Results. The study revealed that most patients suffered from depressive and anxiety disorders, and the level of depression higher among the patients who smoked more. Lack of family support had significant influence on exacerbation of the patient's depressive and anxiety symptoms. Patients who had recently experienced a critical situation presented with more severe COPD symptoms, lower quality of life and a higher level of depression. Higher income of the patients had positive influence on their quality of life. Farmers addicted to alcohol suffered from a higher level of anxiety.

    Spirometry is important in the diagnosis and management of chronic obstructive pulmonary disease (COPD), yet it is a common clinical observation that it is underused though the extent is unclear. This survey aims to examine the use of spirometry in the diagnosis and management of COPD patients in a district in Hong Kong. It is a cross-sectional survey involving four clinic settings: hospital-based respiratory specialist clinic, hospital-based mixed medical specialist clinic, general outpatient clinic (primary care), and tuberculosis and chest clinic. Thirty physician-diagnosed COPD patients were randomly selected from each of the four clinic groups. All of them had a forced expiratory volume in 1 second (FEV1) to forced vital capacity ratio less than 0.70 and had been followed up at the participating clinic for at least 6 months for COPD treatment. Of 126 patients who underwent spirometry, six (4.8%) did not have COPD. Of the 120 COPD patients, there were 111 males and mean post-bronchodilator FEV1 was 46.2% predicted. Only 22 patients (18.3%) had spirometry done during diagnostic workup, and 64 patients (53.3%) had spirometry done ever. The only independent factor predicting spirometry done ever was absence of old pulmonary tuberculosis and follow-up at respiratory specialist clinic. Age, sex, smoking status, comorbidities, duration of COPD, percentage predicted FEV1, body mass index, 6-minute walking distance, and Medical Research Council dyspnea score were not predictive. We conclude that spirometry is underused in general but especially by nonrespiratory physicians and family physicians in the management of COPD patients. More effort at educating the medical community is urgently needed. PMID:24009418

    Stable COPD is marked with various degrees of inflammation throughout large and small airways also in the alveoli which cause mucus hypersecretion, narrowing of the airway, and alveoli damage. Exacerbation is an episode of elevated inflammation. The relation between inflammation response and magnesium has been observed with the increase of proinflammation cytokines in magnesium deficiency. A cross-sectional study of 34 patients who came to RSUP H. Adam Malik (17 stable COPD patients and 17 acute exacerbated COPD patients) was conducted to examine serum magnesium level and spirometry in stable condition. Mean serum magnesium level for stable COPD patients group was 2.09 ± 0.11 mEq/L. It was higher than in the exacerbated COPD patients group 1.69 ± 0.27 mEq/L. Mann–Whitney statistical analysis showed a significant difference in magnesium level between stable COPD and exacerbated COPD groups (p<0.05).

    Chronic Obstructive Pulmonary Disease (COPD) is mainly caused by smoking and presents with shortness of breath that is progressive and irreversible. It is a worldwide health problem and the fourth most common cause of chronic disability and mortality (even in developed countries). It is a complex disease involving both the airway and lung parenchyma. Small-airway fibrosis is the main contributor to physiological airway dysfunction in COPD. One potential mechanism contributing to small-airway fibrosis is epithelial mesenchymal transition (EMT). When associated with angiogenesis (EMT-type-3), EMT may well also be linked to the development of airway epithelial cancer, which is closely associated with COPD and predominantly observed in large airways. Vascular remodeling has also been widely reported in smokers and patients with COPD but the mechanisms behind it are poorly understood. It is quite possible that the process of endothelial to mesenchymal transition (EndMT) is also active in COPD lungs, in addition to EMT. Understanding these pathological mechanisms will greatly enhance our knowledge of the immunopathology of smoking-related lung disease. Only by understanding these processes can new therapies be developed. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

    Chronic obstructive pulmonary disease (COPD) is set to become the third most frequent cause of death and also the third largest cause of global morbidity by 2020. In China, where the population is aging rapidly, COPD has become one of the leading causes of disability and a large economic burden. An epidemiological assessment of the COPD in China is required, with a focus on the number of cases living with disease, main determinants of the disease and time trends. We systematically searched large Chinese bibliographic databases and English databases to identify spirometry-based epidemiological studies of the prevalence of COPD in China diagnosed according to GOLD criteria. We estimated age- and gender-specific prevalence of COPD using a multilevel mixed-effect logistic regression. We also presented the time trends of COPD between 1990 and 2010 by age, gender and setting (urban vs rural). In 1990, the prevalence of COPD ranged from 0.49% (95% CI = 0.29-0.85) in  = 80 years group, and the crude prevalence for China was 2.70% (95% CI = 1.86-3.51). In 2010, the prevalence in  = 80 years was 22.89% (95% CI = 18.13-28.96), with the crude prevalence for China of 3.84% (95% CI = 3.30-4.77). The COPD prevalence in males was about two-fold higher than in females, and it increased with increasing age. Between 1990-2010, the total number of Chinese people living with COPD increased by 66.73%, from 30.90 million (95% CI = 21.28-40.02) in 1990 to 51.52 million (95% CI = 44.26-63.93) in 2010. This increase was most striking in middle age, and greater in females than in males from 30 years up to 64 years. Our estimates, which used an independent approach to acquiring data and development of analytical methods, and were based on a more complete data set, are remarkably similar to those produced recently by the GBD 2013 collaboration, differing by only about 5% in the estimated number of COPD cases in 1990 and by 1% in 2010. COPD is a highly prevalent

    Full Text Available AIM: Chronic obstructive pulmonary disease (COPD is an independent risk factor for cardiovascular morbidity and mortality. The aim of this study was to determine the prevalence of asymptomatic peripheral arterial disease (PAD and the associated risk factors for patients with COPD. METHODS: This prospective cross-sectional study enrolled 427 COPD patients (mean age: 70.0 years without PAD symptoms consecutively. Demographic data, lung function and cardiovascular risk factors were recorded. The ankle-brachial index (ABI was used to detect PAD (ABI<0.90. RESULTS: The overall prevalence of asymptomatic PAD in the COPD patients was 8% (2.5% in the younger participants (<65 years of age, n = 118 and 10% in the elderly participants (≥65 years of age, n = 309. The COPD patients with asymptomatic PAD had a significantly higher rate of hyperlipidemia (47.1% vs. 10.4% and hypertension (79.4% vs. 45.8% than those without asymptomatic PAD (p<0.05. There was no significant difference in lung function (forced vital capacity and forced expiratory volume in one second between the two groups. In multivariate logistic regression, hyperlipidemia was the strongest independent factor for PAD (odds ratio (OR: 6.89, p<0.005, followed by old age (OR: 4.80, hypertension (OR: 3.39 and smoking burden (pack-years, OR: 1.02. CONCLUSIONS: The prevalence of asymptomatic PAD among COPD patients in Taiwan is lower than in Western countries. Hyperlipidemia, old age, hypertension, and smoking burden were the associated cardiovascular risk factors. However, there was no association between lung function and PAD in the COPD patients.

    Full Text Available Aging is an important risk factor for most chronic diseases. Patients with COPD develop more comorbidities than non-COPD subjects. We hypothesized that the development of comorbidities characteristically affecting the elderly occur at an earlier age in subjects with the diagnosis of COPD.We included all subjects carrying the diagnosis of COPD (n = 27,617, and a similar number of age and sex matched individuals without the diagnosis, extracted from the 727,241 records of individuals 40 years and older included in the EpiChron Cohort (Aragon, Spain. We compared the cumulative number of comorbidities, their prevalence and the mortality risk between both groups. Using network analysis, we explored the connectivity between comorbidities and the most influential comorbidities in both groups. We divided the groups into 5 incremental age categories and compared their comorbidity networks. We then selected those comorbidities known to affect primarily the elderly and compared their prevalence across the 5 age groups. In addition, we replicated the analysis in the smokers' subgroup to correct for the confounding effect of cigarette smoking. Subjects with COPD had more comorbidities and died at a younger age compared to controls. Comparison of both cohorts across 5 incremental age groups showed that the number of comorbidities, the prevalence of diseases characteristic of aging and network's density for the COPD group aged 56-65 were similar to those of non-COPD 15 to 20 years older. The findings persisted after adjusting for smoking.Multimorbidity increases with age but in patients carrying the diagnosis of COPD, these comorbidities are seen at an earlier age.

    Full Text Available Introduction Chronic Obstructive Pulmonary Disease (COPD is considered a disease with high morbidity and mortality, even though it is a preventable and treatable disease. Objective To assess the effectiveness of an audiovisual educational material about the knowledge and self-management in COPD. Methods Quasi-experimental design and convenience sample was composed of COPD patients of Pulmonary Rehabilitation (PR (n = 42, in advanced stage of the disease, adults of both genders, and with low education. All subjects answered a specific questionnaire before and post-education audiovisual session, to assess their acquired knowledge about COPD. Results Positive results were obtained in the topics: COPD and its consequences, first symptom identified when the disease is aggravated and physical exercise practice. Regarding the second and third symptoms, it was observed that the education session did not improve this learning, as well as the decision facing the worsening of COPD. Conclusion COPD patients showed reasonable knowledge about the disease, its implications and symptomatology. Important aspects should be emphasized, such as identification of exacerbations of COPD and decision facing this exacerbation.

    Chronic obstructive pulmonary disease (COPD) is a chronic, progressive disease, which consumes a significant proportion of the Australian and New Zealand healthcare budget. Studies have shown that people living with COPD outside of urban areas have higher rates of hospitalisations. Two international reviews have demonstrated reduced hospital admissions and length of stay in people with COPD who participate in an integrated disease management program. However, most studies included in these reviews are in urban settings. The purpose of this review is to explore the type and cost-effectiveness of COPD management interventions located in rural or remote settings of Australia and New Zealand in order to inform planning and ongoing service development in the authors' local health district. Six databases and Google scholar were searched to find literature relating to the availability and cost-effectiveness of non-pharmaceutical interventions for the management of COPD in rural and remote areas of Australia and New Zealand. Two studies were found that met the inclusion criteria. Both studies had small sample sizes, were single intervention studies and showed a positive influence on variables such as number of hospital admissions and length of stay at 12 months post-intervention. However, because of the limited number of studies and the lack of homogeneity of interventions, no conclusions regarding availability and cost-effectiveness of COPD interventions in rural and remote areas of Australia and New Zealand could be drawn. Limited literature exists to inform planning and development of services for people with COPD living in rural and remote areas of Australia and New Zealand. Approximately 50% of pulmonary rehabilitation programs are situated in rural and remote locations in Australia and New Zealand. Outcomes from existing programs need to be reported in a consistent and coordinated manner to allow evaluation of health resource utilisation.

    The recent joint International Society for Pharmacoeconomics and Outcomes Research / Society for Medical Decision Making Modeling Good Research Practices Task Force emphasized the importance of conceptualizing and validating models. We report a new model of chronic obstructive pulmonary disease (COPD) (part of the Galaxy project) founded on a conceptual model, implemented using a novel linked-equation approach, and internally validated. An expert panel developed a conceptual model including causal relationships between disease attributes, progression, and final outcomes. Risk equations describing these relationships were estimated using data from the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study, with costs estimated from the TOwards a Revolution in COPD Health (TORCH) study. Implementation as a linked-equation model enabled direct estimation of health service costs and quality-adjusted life years (QALYs) for COPD patients over their lifetimes. Internal validation compared 3 years of predicted cohort experience with ECLIPSE results. At 3 years, the Galaxy COPD model predictions of annual exacerbation rate and annual decline in forced expiratory volume in 1 second fell within the ECLIPSE data confidence limits, although 3-year overall survival was outside the observed confidence limits. Projections of the risk equations over time permitted extrapolation to patient lifetimes. Averaging the predicted cost/QALY outcomes for the different patients within the ECLIPSE cohort gives an estimated lifetime cost of £25,214 (undiscounted)/£20,318 (discounted) and lifetime QALYs of 6.45 (undiscounted/5.24 [discounted]) per ECLIPSE patient. A new form of model for COPD was conceptualized, implemented, and internally validated, based on a series of linked equations using epidemiological data (ECLIPSE) and cost data (TORCH). This Galaxy model predicts COPD outcomes from treatment effects on disease attributes such as lung function

    Metabolic disorder has been frequently observed in chronic obstructive pulmonary disease (COPD) patients. However, the exact correlation between obesity, which is a complex metabolic disorder, and COPD remains controversial. The current study summarizes a variety of drugs from marine sources that have anti-obesity effects and proposed potential mechanisms by which lung function can be modulated with the anti-obesity activity. Considering the similar mechanism, such as inflammation, shared between obesity and COPD, the study suggests that marine derivatives that act on the adipose tissues to reduce inflammation may provide beneficial therapeutic effects in COPD subjects with high body mass index (BMI).

    Full Text Available Alpha-1-antitrypsin (AAT plays an important role in the pathogenesis of emphysema, the pathological lesion underlying the majority of the manifestations of Chronic Obstructive Pulmonary Disease (COPD. In this study we tested the hypothesis that common AAT polymorphisms influence the risk of developing COPDs. We investigated PiM1 (Ala213Val, PiM2 (Arg101His, PiM3 (Glu376Asp, PiS (Glu264Val and PiZ (Glu342Lys SERPINA1 alleles in 100 COPD patients and 200 healthy controls. No significant differences were observed in allele frequencies between COPD patients and controls, neither did haplotype analysis show significant differences between the two groups. A cross-sectional study revealed no significant relationship between common SERPINA1 polymorphisms (PiM1, PiM2, PiM3 and the emphysematous type of COPD. In addition, FEV1 annual decline, determined during a two-year follow up period, revealed no difference among carriers of the tested polymorphisms.

    Full Text Available Background: a secondary pre-specified analysis of the UPLIFT cohort demonstrated that the inclusion of tiotropium bromide in the routine care of GOLD stage II (moderate chronic obstructive pulmonary disease (COPD patients is associated with stronger improvements of survival, quality of life, and exacerbation rate than those shown in the total cohort; in this subgroup, tiotropium furthermore induces a significant reduction in the rate of FEV1 decline.Objective: to adapt the Spiriva® model, originally built to evaluate cost-effectiveness of tiotropium inclusion in the general COPD population, to GOLD II patients.Methods: the Spiriva® model is a probabilistic Markov patient-level simulation developed over a lifetime horizon to compare outcomes associated with the inclusion of tiotropium in routine care (RC for COPD treatment with those obtained with RC alone. Patients are characterised by gender, age, height, smoking status and FEV1. Model structure and sources have been maintained unvaried, except for demographic characteristics, specific for GOLD II patients, as extrapolated from an Italian observational study, and tiotropium efficacy, based on the secondary analysis of GOLD II UPLIFT patients. As in the original model, only direct health care costs are considered.Results: patients treated with tiotropium on average (95% CI gain 0.70 (0.00/7.23 LYs or 0.77 (0.02/4.67 QALYs compared to RC. The incremental lifetime cost is € 3,520 (-6,391/26,686, meaning that the incremental cost required to gain a QALY (incremental cost-effectiveness ratio – ICER is equal to € 4,548. Sensitivity analysis shows that tiotropium has a 50% probability of being cost-effective for a willingness-to-pay (WTP around 4,600 €/QALY; 100% probability is achieved with a WTP of € 9,300.Conclusions: the adoption of a strategy based on the inclusion of tiotropium from the early COPD stages represents good value for money in Italy, as the ICER estimated for GOLD II

    Chronic obstructive pulmonary disease (COPD) has historically been considered a disease of older, white, male smokers, as illustrated in Frank Netter's classic images of the 'pink puffer' and 'blue bloater'. However, women may be more susceptible to COPD than men, and the disease course may be reflective of that increased susceptibility. From a review of epidemiological data of COPD, we found differences in the way men and women present with COPD symptoms, a bias in the way COPD symptoms are treated in men and women, and differences in susceptibility to airway obstruction based on age, sex, and smoking history. These data show that classic stereotypes of COPD - including male predominance - should be abandoned, and that there are not two but multiple COPD phenotypes, which are characterised by differences between women and men in susceptibility, symptoms, and disease progression. These differences impact on physician perception. Although further research into this concept is needed, the differences we found should prompt, in the short term, changes in the way (and in whom) COPD is evaluated, diagnosed, and treated; in the long term, these differences should prompt research into the prognosis of COPD based on sex differences.

    Full Text Available Abstract Background To evaluate the influence of heart disease on clinical characteristics, quality of life, use of health resources, and costs of patients with COPD followed at primary care settings under common clinical practice conditions. Methods Epidemiologic, observational, and descriptive study (EPIDEPOC study. Patients ≥ 40 years of age with stable COPD attending primary care settings were included. Demographic, clinical characteristics, quality of life (SF-12, seriousness of the disease, and treatment data were collected. Results were compared between patients with or without associated heart disease. Results A total of 9,390 patients with COPD were examined of whom 1,770 (18.8% had heart disease and 78% were males. When comparing both patient groups, significant differences were found in the socio-demographic characteristics, health profile, comorbidities, and severity of the airway obstruction, which was greater in patients with heart disease. Differences were also found in both components of quality of life, physical and mental, with lower scores among those patients with heart disease. Higher frequency of primary care and pneumologist visits, emergency-room visits and number of hospital admissions were observed among patients with heart diseases. The annual total cost per patient was significantly higher in patients with heart disease; 2,937 ± 2,957 vs. 1,749 ± 2,120, p Conclusion Patients with COPD plus heart disease had greater disease severity and worse quality of life, used more healthcare resources and were associated with greater costs compared to COPD patients without known hearth disease.

    Beta-blockers are commonly prescribed for patients with cardiovascular disease. Providers have been wary of treating chronic obstructive pulmonary disease (COPD) patients with beta-blockers due to concern for bronchospasm, but retrospective studies have shown that cardio-selective beta-blockers are safe in COPD and possibly beneficial. However, these benefits may reflect symptom improvements due to the cardiac effects of the medication. The purpose of this study is to evaluate associations between beta-blocker use and both exacerbation rates and longitudinal measures of lung function in two well-characterized COPD cohorts. We retrospectively analyzed 1219 participants with over 180 days of follow up from the STATCOPE trial, which excluded most cardiac comorbidities, and from the placebo arm of the MACRO trial. Primary endpoints were exacerbation rates per person-year and change in spirometry over time in association with beta blocker use. Overall 13.9% (170/1219) of participants reported taking beta-blockers at enrollment. We found no statistically significant differences in exacerbation rates with respect to beta-blocker use regardless of the prevalence of cardiac comorbidities. In the MACRO cohort, patients taking beta-blockers had an exacerbation rate of 1.72/person-year versus a rate of 1.71/person-year in patients not taking beta-blockers. In the STATCOPE cohort, patients taking beta-blockers had an exacerbation rate of 1.14/person-year. Patients without beta-blockers had an exacerbation rate of 1.34/person-year. We found no detrimental effect of beta blockers with respect to change in lung function over time. We found no evidence that beta-blocker use was unsafe or associated with worse pulmonary outcomes in study participants with moderate to severe COPD.

    Chronic obstructive pulmonary disease (COPD) is characterised by persistent respiratory symptoms and chronic airflow limitation, and is associated with exacerbations and comorbidities. Advances in the management of COPD are updated quarterly in the national COPD guidelines, the COPD-X plan, published by Lung Foundation Australia in conjunction with the Thoracic Society of Australia and New Zealand and available at http://copdx.org.au. Main recommendations: Spirometry detects persistent airflow limitation (post-bronchodilator FEV1/FVC COPD patients.Short- and long-acting inhaled bronchodilators and, in more severe disease, anti-inflammatory agents (inhaled corticosteroids) should be considered in a stepwise approach.Given the wide range of inhaler devices available, inhaler technique and adherence should be checked regularly.Smoking cessation is essential, and influenza and pneumococcal vaccinations reduce the risk of exacerbations.A plan of care should be developed with the multidisciplinary team. COPD action plans reduce hospitalisations and are recommended as part of COPD self-management.Exacerbations should be managed promptly with bronchodilators, corticosteroids and antibiotics as appropriate to prevent hospital admission and delay COPD progression.Comorbidities of COPD require identification and appropriate management.Supportive, palliative and end-of-life care are beneficial for patients with advanced disease.Education of patients, carers and clinicians, and a strong partnership between primary and tertiary care, facilitate evidence-based management of COPD. Changes in management as result of the guideline: Spirometry remains the gold standard for diagnosing airflow obstruction and COPD. Non-pharmacological and pharmacological treatment should be used in a stepwise fashion to control symptoms and reduce exacerbation risk.

    Chronic obstructive pulmonary disease (COPD) severely hinders quality of life for those affected and is costly to the health care system. Care gaps in areas such as pharmacotherapy, inhaler technique, and knowledge of disease are prevalent, particularly for vulnerable populations served by community clinics. Non-professionally licensed health coaches have been shown to be an effective and cost-efficient solution in bridging care gaps and facilitating self-management for patients with other chronic diseases, but no research to date has explored their efficacy in improving care for people living with COPD. This is multi-site, single blinded, randomized controlled trial evaluates the efficacy of health coaches to facilitate patient self-management of disease and improve quality of life for patients with moderate to severe COPD. Spirometry, survey, and an exercise capacity test are conducted at baseline and at 9 months. A short survey is administered by phone at 3 and 6 months post-enrollment. The nine month health coaching intervention focuses on enhancing disease understanding and symptom awareness, improving use of inhalers; making personalized plans to increase physical activity, smoking cessation, or otherwise improve disease management; and facilitating care coordination. The results of this study will provide evidence regarding the efficacy and feasibility of health coaching to improve self-management and quality of life for urban underserved patients with moderate to severe COPD.

    BACKGROUND Serum uric acid (sUA) levels were previously found to be correlated with hypoxic states. We aimed to determine the levels of sUA and sUA/creatinine ratios in stable COPD patients and to evaluate whether sUA level and sUA/creatinine ratio can be used as predictors of exacerbation risk and disease severity. MATERIAL AND METHODS This cross-sectional study included stable COPD patients and healthy controls. The sUA levels and sUA/creatinine ratios in each group were evaluated and their correlations with the study parameters were investigated. ROC analyses for exacerbation risk and disease severity were reported. RESULTS The study included 110 stable COPD patients and 52 healthy controls. The mean sUA levels and sUA/creatinine ratios were significantly higher in patients with COPD compared to healthy controls. The most common comorbidities in COPD patients were hypertension, diabetes, and coronary artery disease. While sUA levels were significantly higher in patients with hypertension (p=0.002) and malignancy (p=0.033), sUA/creatinine ratios was higher in patients with malignancy (p=0.004). The ROC analyses indicated that sUA/creatinine ratios can be more useful than sUA levels in predicting exacerbation risk (AUC, 0.586 vs. 0.426) and disease severity (AUC, 0.560 vs. 0.475) especially at higher cut-off values, but with low specificity. CONCLUSIONS Our study suggested that sUA levels and sUA/creatinine ratios increased in patients with stable COPD, especially among patients with certain comorbidities compared to healthy controls. At higher cut-off values, sUA levels and especially sUA/creatinine ratios, might be useful in predicting COPD exacerbation risk and disease severity. Also, their association with comorbidities, especially with malignancy and hypertension, may benefit from further investigation.

    The efficacy of disease management programs in the treatment of patients with chronic obstructive pulmonary disease (COPD) remains uncertain. To study the effect of disease management (DM) added to recommended care (RC) in ambulatory COPD patients. In this trial, 1,202 COPD patients (age >40 years), with moderate to very severe airflow limitation were randomly assigned either to DM plus RC (study intervention) or to RC alone (control intervention). RC included follow-up by pulmonologists; inhaled long-acting bronchodilators and corticosteroids; smoking cessation intervention; nutritional advice and psychosocial support when indicated, and supervised physical activity sessions. DM, delivered by trained nurses during patients' visits to the designated COPD centers and remote contacts with the patients between these visits, included patient self-care education; monitoring patients' symptoms and adherence to treatment; provision of advice in case of acute disease exacerbation, and coordination of care vis-à-vis other healthcare providers. The primary composite endpoint was first hospital admission for respiratory symptoms or death from any cause. During 3,537 patient-years, 284 (47.2%) patients in the control group and 264 (44.0%) in the study intervention group had a primary endpoint event. The median (range) time elapsed until a primary endpoint event was 1.0 (0-4.0) years among patients assigned to the study intervention and 1.1 (0-4.1) years among patients assigned to the control intervention; adjusted hazard ratio, 0.92 (95%CI: 0.77 to 1.08). DM added to RC was not superior to RC alone in delaying first hospital admission or death among ambulatory COPD patients.

Co-occurrence analysis suggests the presence of networks of co-occurring bacteria. Four communities of positively correlated bacteria were revealed. The microbial communities can clearly be distinguished by their associations with the CT defined disease phenotype.Our findings indicate that CT detectable structural changes in the lung of COPD patients, which we termed severe subtypes, are associated with alterations in bacterial communities, which may induce further changes in the interaction between microbes and host cells. This might result in a changed interplay with the host immune system.

    Inflammation is an important constituent of the pathology of chronic obstructive pulmonary disease (COPD), leading to alveolar destruction and airway remodelling. The aim of this study was to assess the difference in plasma biomarkers of inflammation between asymptomatic smokers and patients with COPD. We used commercially available enzyme-linked immunosorbent assay kits to measure the plasma levels of tumour necrosis factor-alpha (TNF-alpha), interleukin-8 (IL-8), matrix metalloproteinase-9 (MMP-9), monocyte chemotactic protein-1 (MCP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and tissue inhibitor of metalloproteinase-2 (TIMP-2) on two occasions with a 2-week interval in patients with COPD (n = 20), asymptomatic smokers (n = 10) and healthy lifelong non-smokers (n = 10). The participants were characterised clinically, physiologically and by quantitative computed tomography by measuring the relative area of emphysema below -910 Hounsfield units (RA-910). The results of the biomarker measurements on the two occasions were highly reproducible. Patients with COPD had significantly higher plasma levels of IL-8 (P = 0.004) and significantly lower levels of TIMP-1 (P = 0.02) than smokers and non-smokers. There was no statistically significant difference between the three groups in the level of TNF-alpha, MMP-9, MCP-1 and TIMP-2. The IL-8/TIMP-1 ratio correlated significantly with the degree of airway obstruction measured as forced expiratory volume in 1 second (FEV(1)) % predicted (r = -0.47, P < 0.01); with the diffusion capacity (r = -0.41, P < 0.01); and with the grade of emphysema measured as RA-910 (r = 0.39, P = 0.01). These findings suggest that the measurement of plasma biomarkers, such as IL-8/TIMP-1, may aid to discriminate patients with COPD from smokers at lower risk of developing COPD.

    ALAT-2014 COPD Clinical Practice Guidelines used clinical questions in PICO format to compile evidence related to risk factors, COPD screening, disease prognosis, treatment and exacerbations. Evidence reveals the existence of risk factors for COPD other than tobacco, as well as gender differences in disease presentation. It shows the benefit of screening in an at-risk population, and the predictive value use of multidimensional prognostic indexes. In stable COPD, similar benefits in dyspnea, pulmonary function and quality of life are achieved with LAMA or LABA long-acting bronchodilators, whereas LAMA is more effective in preventing exacerbations. Dual bronchodilator therapy has more benefits than monotherapy. LAMA and combination LABA/IC are similarly effective, but there is an increased risk of pneumonia with LABA/IC. Data on the efficacy and safety of triple therapy are scarce. Evidence supports influenza vaccination in all patients and anti-pneumococcal vaccination in patients <65years of age and/or with severe airflow limitation. Antibiotic prophylaxis may decrease exacerbation frequency in patients at risk. The use of systemic corticosteroids and antibiotics are justified in exacerbations requiring hospitalization and in some patients managed in an outpatient setting. Copyright © 2014 SEPAR.

Retrospective study including 153 male patients hospitalized for COPD exacerbation from January 2009 to June 2012. Patients were classified into 4 phenotypes according to Burgel's classification. Patients were divided into four phenotypes: phenotype (PH)1: (n=68), PH2: (n=33), PH3: (n=25) and PH4: (n=27). Mean age for PH1, 2, 3 and 4 was: 61, 74, 56 and 72 years. The number of exacerbations per year was higher in PH1. Dyspnea was more important in PH1 and 4. Hypercapnia on admission was higher in PH4. Non invasive ventilation and transfer to resuscitation unit were more frequently mandatory in PH3 and 4.   Death occurred 2% of PH1 and 5% of PH4. Hospitalization duration was more important in PH4. COPD patients are heterogenous and belong to different phenotypes. The characteristics of the exacerbations and their prognosis widely differ according to these different groups. In Tunisia, it seems that patients who had moderate respiratory functional tests impairment are the lowest responders to treatment with a higher frequency of resuscitation unit transfer.

    Spirometry is practically the only tool to evaluate pulmonary functions. Other automatic systems comparable to spirometry are expected. A fiber-grating (FG) vision sensor is a non-contact respiratory monitoring system to detect changes in volumes by measuring the movement of laser spots on the body surface. We examined the contributions of the FG sensor to evaluating pulmonary functions. The FG sensor showed a linear correlation with spirometry in tidal volumes (TV) obtained from five controls (R = 0.98, P < 0.0001). We also showed agreement of TV between the two devices using Bland–Altman analysis. TV measured by the FG sensor were reproducible and applicable to distinct subjects. To detect airway obstruction, we performed forced expiration in controls (n = 16) and chronic obstructive pulmonary disease (COPD) patients (n = 18) with the FG sensor and spirometry. Forced expiratory volume in 1 s (FEV 1 ) and FEV 1 /forced vital capacity in COPD patients were lower than those in controls by the FG sensor. In addition, prolonged expiration in natural breathing by the FG sensor was related to airflow limitation by spirometry. The FG sensor was helpful to measure volume changes and to evaluate pulmonary functions in controls and patients with COPD. Its upcoming clinical applications are promising for simplicity and feasibility

    The Global Initiative for Chronic Obstructive Lung Disease (GOLD guideline) for patients with chronic obstructive pulmonary disease does not adequately reflect the impact of the disease because does not take into account daily physical activity (DPA). Forty eight patients (12 in each GOLD group) were prospectively recruited. DPA was evaluated by accelerometer. Patients were classified into 3 levels of activity (very inactive, sedentary, active). No significant differences in levels of physical activity among GOLD groups (P=.361) were observed. The percentages of very inactive patients were 33% in group A, 42% in group B, 42% in group C and 59% in group D. In addition, high percentage of sedentary patients were observed through 4 groups, in group A (50%), B and C (42%, each), and group D (41%). COPD patients has very low levels of physical activity at all stages of GOLD classification even those defined as low impact (such as GOLD A). Is necessary to detect patients at risk who might benefit from specific interventions. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    The Korea Chronic Obstructive Pulmonary Disorders Subgroup Study Team (Korea COPD Subgroup Study team, KOCOSS) is a multicenter observational study that includes 956 patients (mean age 69.9 ± 7.8 years) who were enrolled from 45 tertiary and university-affiliated hospitals from December 2011 to October 2014. The initial evaluation for all patients included pulmonary function tests (PFT), 6-minute walk distance (6MWD), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C). Here, we report the comparison of baseline characteristics between patients with early- (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage I and II/groups A and B) and late-stage COPD (GOLD stage III and IV/groups C and D). Among all patients, the mean post-bronchodilator FEV1 was 55.8% ± 16.7% of the predicted value, and most of the patients were in GOLD stage II (520, 56.9%) and group B (399, 42.0%). The number of exacerbations during one year prior to the first visit was significantly lower in patients with early COPD (0.4 vs. 0.9/0.1 vs. 1.2), as were the CAT score (13.9 vs. 18.3/13.5 vs. 18.1), mMRC (1.4 vs. 2.0/1.3 vs.1.9), and SGRQ-C total score (30.4 vs. 42.9/29.1 vs. 42.6) compared to late-stage COPD (all P COPD will provide important information towards early detection, proper initial management, and design of future studies.

    2013-01-01

    In this review we demonstrate that patients with chronic obstructive pulmonary disease (COPD) frequently report sinonasal symptoms. Furthermore, we present evidence that smoking on its own can cause nasal disease, and that in COPD patients, nasal inflammation mimics that of the bronchi. All...... this evidence suggests that COPD related sinonasal disease does exist and that smoking on its own rather than systemic inflammation triggers the condition. However, COPD related sinonasal disease remains to be characterized in terms of symptoms and endoscopic findings. In addition, more studies are needed...... to quantify the negative impact of sinonasal symptoms on the quality of life in COPD patients....

    COPD is a highly complex disease to manage as patients show great variation in symptoms and limitations in daily life. In the last decade self-management support of COPD has been introduced as an effective method to improve quality and efficiency of care, and to reduce healthcare costs. Despite the urge to change the organisation of health care and the potential of eHealth to support this, large-scale implementation in daily practice remains behind, especially in the Netherlands. We designed a multilevel study, called e-Vita, to investigate different organisational implementation methods of a self-management web portal to support and empower patients with COPD in three different primary care settings. Using a parallel cohort design, the clinical effects of the web portal will be assessed using an interrupted times series (ITS) study design and measured according to changes in health status with the Clinical COPD Questionnaire (CCQ). The different implementations and net benefits of self-management through eHealth on clinical outcomes will be evaluated from human, organisational, and technical perspectives. To our knowledge this is the first study to combine different study designs that enable simultaneous investigation of clinical effects, as well as effects of different organisational implementation methods whilst controlling for confounding effects of the organisational characteristics. We hypothesize that an implementation with higher levels of personal assistance, and integrated in an existing care program will result in increased use of and satisfaction with the platform, thereby increasing health status and diminishing exacerbation and hospitalisation.

    The Asia-Pacific Burden of Respiratory Diseases (APBORD) study is a cross-sectional, observational one which has used a standard protocol to examine the disease and economic burden of allergic rhinitis (AR), asthma, chronic obstructive pulmonary disorder (COPD), and rhinosinusitis across the Asia-Pacific region. Here, we report on symptoms, healthcare resource use, work impairment, and associated costs in Korea. Consecutive participants aged ≥18 years with a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Participants and their treating physician completed a survey detailing respiratory symptoms, healthcare resource use, and work productivity and activity impairment. Costs included direct medical cost and indirect cost associated with lost work productivity. The study enrolled 999 patients. Patients were often diagnosed with multiple respiratory disorders (42.8%), with asthma/AR and AR/rhinosinusitis the most frequently diagnosed combinations. Cough or coughing up phlegm was the primary reason for the medical visit in patients with a primary diagnosis of asthma and COPD, whereas nasal symptoms (watery runny nose, blocked nose, and congestion) were the main reasons in those with AR and rhinosinusitis. The mean annual cost for patients with a respiratory disease was US$8,853 (SD 11,245) per patient. Lost productivity due to presenteeism was the biggest contributor to costs. Respiratory disease has a significant impact on disease burden in Korea. Treatment strategies for preventing lost work productivity could greatly reduce the economic burden of respiratory disease.

    Full Text Available Socio-economic, cultural and environmental factors are becoming increasingly important determinants of chronic obstructive pulmonary disease (COPD. We conducted a study to investigate socio-demographic, lifestyle and clinical factors, and to assess their role as predictors of acute events (mortality or hospitalization for respiratory causes in a group of COPD patients.Subjects were recruited among outpatients who were undertaking respiratory function tests at the Pneumology Unit of the Sant'Orsola-Malpighi Hospital, Bologna. Patients were classified according to the GOLD Guidelines.229 patients with COPD were included in the study, 44 with Mild, 68 Moderate, 52 Severe and 65 Very Severe COPD (GOLD stage. Significant differences among COPD stage, in terms of smoking status and fragility index, were detected. COPD stage significantly affected the values of all clinical tests (spirometry and ABG analysis. Kaplan-Meier estimates showed a significant difference between survival curves by COPD stage with lower event-free probability in very severe COPD stage. Significant risk factors for acute events were: underweight (HR = 4.08; 95% CI 1.01-16.54, having two or more comorbidities (HR = 4.71; 95% CI 2.52-8.83, belonging to moderate (HR = 3.50; 95% CI 1.01-12.18 or very severe COPD stage (HR = 8.23; 95% CI 2.35-28.85.Our findings indicate that fragility is associated with COPD stage and that comorbidities and the low body mass index are predictors of mortality or hospitalization. Besides spirometric analyses, FeNO measure and comorbidities, body mass index could also be considered in the management and monitoring of COPD patients.

    To study if the coexistence of chronic obstructive pulmonary disease (COPD) in patients diagnosed with acute heart failure (AHF) at the emergency department (ED) has an impact on short- and long-term outcomes. The EAHFE-COPD study included patients who attended in 34 Spanish EDs for AHF. We compared patients with AHF plus COPD with patients with AHF in whom COPD was neither diagnosed nor excluded by functional respiratory tests (FRT). Outcome analysis included all-cause mortality, prolonged hospitalization, and ED revisit. Crude results were adjusted by differences between patients with and without COPD. We included 8099 patients with AHF, 2069 having COPD (25.6%; AHF-COPD-known). Compared with AHF-COPD-unknown, AHF-COPD-known differed in 20 variables. After adjusting for differences between the two groups, AHF-COPD-known patients showed no significant differences in 30-day mortality (OR=0.89; 95% CI=0.71-1.11), prolonged hospitalization in general wards (OR=1.04; 95% CI=0.89-1.22) or SSU (OR=1.38; 95% CI=0.97-1.97), and 1-year mortality (HR: 1.02; 95% CI=0.89-1.17), but showed a higher 30-day revisit rate (OR=1.32; 95% CI=1.13-1.54). In patients attending the ED for AHF, the coexistence of COPD is only associated with an increased risk of short-term ED revisit, but not prolonged hospitalization and short- or long-term mortality.

    COPD exacerbations and hospitalizations have been associated with poor prognosis for the COPD patient. 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. 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. 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. 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.

    Full Text Available Introduction: The value of monitoring physiological parameters to predict chronic obstructive pulmonary disease (COPD exacerbations is controversial. A few studies have suggested benefit from domiciliary monitoring of vital signs, and/or lung function but there is no existing systematic review. Objectives: To conduct a systematic review of the effectiveness of monitoring physiological parameters to predict COPD exacerbation. Methods: An electronic systematic search compliant with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines was conducted. The search was updated to April 6, 2016. Five databases were examined: Medical Literature Analysis and Retrieval System Online, or MEDLARS Online (Medline, Excerpta Medica dataBASE (Embase, Allied and Complementary Medicine Database (AMED, Cumulative Index of Nursing and Allied Health Literature (CINAHL and the Cochrane clinical trials database. Results: Sixteen articles met the pre-specified inclusion criteria. Fifteen of these articules reported positive results in predicting COPD exacerbation via monitoring of physiological parameters. Nine studies showed a reduction in peripheral oxygen saturation (SpO2% prior to exacerbation onset. Three studies for peak flow, and two studies for respiratory rate reported a significant variation prior to or at exacerbation onset. A particular challenge is accounting for baseline heterogeneity in parameters between patients. Conclusion: There is currently insufficient information on how physiological parameters vary prior to exacerbation to support routine domiciliary monitoring for the prediction of exacerbations in COPD. However, the method remains promising.

    Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is defined as having both features of asthma and COPD, which are airway hyper-responsiveness and incompletely reversible airway obstruction. However, socioeconomic impact of ACOS have not been well appreciated. Adults with available wheezing history and acceptable spirometry were selected from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV) in 2007-2009. Their data were merged with the Korean National Health Insurance claim data. 'Asthma group' was defined as having self-reported wheezing history and FEV 1 /FVC ≥0.7, 'COPD group' was defined as having FEV 1 /FVC COPD, 8.4%; asthma, 5.8% and NAD, 83.6%. Total length of healthcare utilization and medical costs of ACOS group was the top among four groups (PCOPD group (P=0.025). Multiple linear regression analyses showed that ACOS group (β=12.63, P<0.001) and asthma group (β=6.14, P<0.001) were significantly associated with longer duration of healthcare utilization and ACOS group (β=350,475.88, P=0.008) and asthma group (β=386,876.81, P<0.001) were associated with higher medical costs. This study demonstrated that ACOS independently influences healthcare utilization after adjusting several factors. In order to utilize limited medical resources efficiently, it may be necessary to find and manage ACOS patients.

    Chronic Obstructive Pulmonary Disease (COPD) frequently coexists with other diseases. Whereas COPD action plans are currently part of usual care, they are less suitable and potentially unsafe for use in the presence of comorbidities. This study evaluates whether an innovative treatment approach directed towards COPD and frequently existing comorbidities can reduce COPD exacerbation days. We hypothesise that this approach, which combines self-initiated action plans and nurse support, will accelerate proper treatment actions and lead to better control of deteriorating symptoms. In this multicenter randomised controlled trial we aim to include 300 patients with COPD (GOLD II-IV), and with at least one comorbidity (cardiovascular disease, diabetes, anxiety and/or depression). Patients will be recruited from hospitals in the Netherlands (n = 150) and Australia (n = 150) and will be assigned to an intervention or control group. All patients will learn to complete daily symptom diaries for 12-months. Intervention group patients will participate in self-management training sessions to learn the use of individualised action plans for COPD and comorbidities, linked to the diary. The primary outcome is the number of COPD exacerbation days. Secondary outcomes include hospitalisations, quality of life, self-efficacy, adherence, patient's satisfaction and confidence, health care use and cost data. Intention-to-treat analyses (random effect negative binomial regression and random effect mixed models) and cost-effectiveness analyses will be performed. Prudence should be employed before extrapolating the use of COPD specific action plans in patients with comorbidities. This study evaluates the efficacy of tailored action plans for both COPD and common comorbidities. Copyright © 2013 Elsevier Inc. All rights reserved.

    Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic diseases of adults and is a major cause of chronic morbidity and mortality throughout the world. It is the cause of physical and mental suffering for the patient, significantly impairs quality of life, reduces the vital activity and affects the patient's life in its various aspects. In 2012, the nationwide survey was conducted in COPD outpatients with a history of smoking exploring the various factors of the disease and its effects on the health and life of the patient. The purpose of the analysis presented here is to assess the impact of COPD and tobacco smoking on the patient's health and life. Data were collected from patients by their physicians during routine visit with usage of specifically prepared questionnaire for this study. Patients over 35 years of age, with diagnosed COPD, current or past smokers were recruited from outpatients settings. The study involved 10,365 patients with COPD. Representative sample of 2,967 questionnaires were randomly drawn for the statistical analysis. The mean age of responders was 61.15 ± 10.25 years, 33.98% of participants were women, 56.73% were current smokers and 43.37% declared smoking in the past. The largest number of patients had COPD in a moderate degree (II - acc. to GOLD 2010) - 55.38%, sequentially mild (I) - 21.40%, and severe (III) - 19.96%, the smallest group were people with very severe degree of disease (IV) - 3.27%. Using the new classification of the COPD severity (acc. to GOLD 2013), the largest group of patients were less symptomatic (mMRC ) subjects who had a low risk (A) - 52.67%, but in fact a second group of patients were subjects with severe symptoms and a high risk (D) - 20 45% , sequentially - patients with low severity of symptoms, but a high risk (C) - 16.16% , and severe symptoms and a low risk - 10.72% (B). Patients most often reported that COPD affects their activity in sport (83.45% of respondents), than in living

    We have developed a method called intersection profile method to construct a 4D-MRI (3D+time) from time-series of 2D-MRI. The basic idea is to find the best matching of the intersection profile from the time series of 2D-MRI in sagittal plane (navigator slice) and time series of 2D-MRI in coronal plane (data slice). In this study, we use 4D-MRI to semiautomatically extract the right diaphragm motion of 16 subjects (8 healthy subjects and 8 COPD patients). The diaphragm motion is then evaluated quantitatively by calculating the displacement of each subjects and normalized it. We also generate phase-length map to view and locate paradoxical motion of the COPD patients. The quantitative results of the normalized displacement shows that COPD patients tend to have smaller displacement compared to healthy subjects. The average normalized displacement of total 8 COPD patients is 9.4mm and the average of normalized displacement of 8 healthy volunteers is 15.3mm. The generated phase-length maps show that not all of the COPD patients have paradoxical motion, however if it has paradoxical motion, the phase-length map is able to locate where does it occur.

    Chronic obstructive pulmonary disease (COPD) is the cause of substantial economic and social burden. We evaluated the temporal trends of hospitalizations from acute exacerbation of COPD and determined its outcome and financial impact using the National (Nationwide) Inpatient Sample (NIS) databases (2002-2010). Individuals aged ≥ 18 years were included. Subjects who were hospitalized with primary diagnosis of COPD exacerbation and those who were admitted for other causes but had underlying acute exacerbation of COPD (secondary diagnosis) were captured by International Classification of Diseases-Ninth Revision (ICD-9) codes. The hospital outcomes and length of stay were determined. Multivariate logistic regression was used to identify the independent predictors of inpatient mortality. Overall acute exacerbation of COPD-related hospitalizations accounted for nearly 3.31% of all hospitalizations in the year 2002. This did not change significantly to year 2010 (3.43%, p = 0.608). However, there was an increase in hospitalization with secondary diagnosis of COPD. Elderly white patients accounted for most of the hospitalizations. Medicare was the primary payer source for most of the hospitalizations (73-75%). There was a significant decrease in inpatient mortality from 4.8% in 2002 to 3.9% in 2010 (slope -0.096, p < 0.001). Similarly, there was a significant decrease in average length of stay from 6.4 days in 2002 to 6.0 days in 2010 (slope -0.042, p < 0.001). Despite this, the hospitalization cost was increased substantially from $22,187 in 2002 to $38,455 in 2010. However, financial burden has increased over the years.

    Full Text Available Airway diseases are highly prevalent worldwide; however, the prevalence of these diseases is underestimated. Although these diseases present several common characteristics, they have different clinical outcomes. The differentiation between asthma, chronic obstructive pulmonary disease and bronchiectasis in the early stage of disease is extremely important for the adoption of appropriate therapeutic measures. However, because of the high prevalence of these diseases and the common pathophysiological pathways, some patients with different diseases may present with similar symptoms. The objective of this review is to highlight the similarities and differences between these diseases in terms of the risk factors, pathophysiology, symptoms, diagnosis and treatment.

Successful dietary intervention calls for calculations of resting metabolic rate (RMR. One disease-specific prediction equation for RMR exists based on mainly male patients. To construct a disease-specific equation for RMR based on measurements in underweight or weight-losing women and men with COPD, RMR was measured by indirect calorimetry in 30 women and 11 men with a diagnosis of COPD and body mass index <21 kg/m2. The following variables, possibly influencing RMR were measured: length, weight, middle upper arm circumference, triceps skinfold, body composition by dual energy x-ray absorptiometry and bioelectrical impedance, lung function, and markers of inflammation. Relations between RMR and measured variables were studied using univariate analysis according to Pearson. Gender and variables that were associated with RMR with a P value <0.15 were included in a forward multiple regression analysis. The best-fit multiple regression equation included only fat-free mass (FFM: RMR (kJ/day = 1856 + 76.0 FFM (kg. To conclude, FFM is the dominating factor influencing RMR. The developed equation can be used for prediction of RMR in underweight COPD patients.Keywords: pulmonary disease, chronic obstructive, basal metabolic rate, malnutrition, body composition

    Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

    Full Text Available Abstract Background Low therapeutic adherence to medication is very common. Clinical effectiveness is related to dose rate and route of administration and so poor therapeutic adherence can reduce the clinical benefit of treatment. The therapeutic adherence of patients with chronic obstructive pulmonary disease (COPD is extremely poor according to most studies. The research about COPD adherence has mainly focussed on quantifying its effect, and few studies have researched factors that affect non-adherence. Our study will evaluate the effectiveness of a multifactor intervention to improve the therapeutic adherence of COPD patients. Methods/Design A randomized controlled clinical trial with 140 COPD diagnosed patients selected by a non-probabilistic method of sampling. Subjects will be randomly allocated into two groups, using the block randomization technique. Every patient in each group will be visited four times during the year of the study. Intervention: Motivational aspects related to adherence (beliefs and behaviour: group and individual interviews; cognitive aspects: information about illness; skills: inhaled technique training. Reinforcement of the cognitive-emotional aspects and inhaled technique training will be carried out in all visits of the intervention group. Discussion Adherence to a prescribed treatment involves a behavioural change. Cognitive, emotional and motivational aspects influence this change and so we consider the best intervention procedure to improve adherence would be a cognitive and emotional strategy which could be applied in daily clinical practice. Our hypothesis is that the application of a multifactor intervention (COPD information, dose reminders and reinforcing audiovisual material, motivational aspects and inhalation technique training to COPD patients taking inhaled treatment will give a 25% increase in the number of patients showing therapeutic adherence in this group compared to the control group. We will

    Airway smooth muscle (ASM) remodeling is a hallmark in chronic obstructive pulmonary disease (COPD), and nicotinamide-adenine dinucleotide phosphate (NADPH) oxidases (NOXs) produced reactive oxygen species (ROS) play a crucial role in COPD pathogenesis. In the present study, the expression of NOX4 and its correlation with the ASM hypertrophy/hyperplasia, clinical pulmonary functions, and the expression of transforming growth factor β (TGF- β ) in the ASM of COPD small airways were investigated by semiquantitative morphological and/or immunohistochemistry staining methods. The results showed that an elevated expression of NOX4 and TGF- β , along with an increased volume of ASM mass, was found in the ASM of small airways in COPD patients. The abundance of NOX4 protein in the ASM was increased with disease severity and inversely correlated with the pulmonary functions in COPD patients. In addition, the expression of NOX4 and ASM marker α -SMA was colocalized, and the increased NOX4 expression was found to accompany an upregulated expression of TGF- β in the ASM of small airways of COPD lung. These results indicate that NOX4 may be a key regulator in ASM remodeling of small airway, in part through a mechanism interacting with TGF- β signaling in the pathogenesis of COPD, which warrants further investigation.

    Chronic obstructive pulmonary disease (COPD) is a disease that is characterized by chronic airflow limitation, a variety of pathological changes in the lungs, significant extrapulmonary manifestations, and severe comorbidities which may further aggravate the course of COPD [GOLD, 2013]. Intensity of systemic manifestations increases with the progression of obstruction, therefore the abovementioned symptoms are often overlooked and become apparent in the later stages of the disease. Systemic manifestations impair the quality of life, lead to early disability and significantly contribute to mortality in patients with COPD. Diseases of cardiovascular and musculoskeletal systems are the most serious and socially significant systemic manifestations of chronic obstructive pulmonary disease. Currently, there is no doubt that the activation of non-specific and specific immune responses in patients with COPD is associated with the influence of a number of universal mediators, among which a special place belongs to the cytokine network that controls implementation processes of the immune and inflammatory reactivity. The aim of our work was to increase the effectiveness of treatment in patients with chronic obstructive pulmonary disease in combination with osteoarthritis based on the study of clinical course, assessment of patient's life quality and substantiation of pharmacological correction. The work was conducted on the basis of Poltava Regional Clinical Hospital named after N.V. Sklifosovskiy. The study was carried out at Research Institute for Genetics and Immunological Grounds of Pathology and Pharmacogenetics of Higher State Educational Establishment of Ukraine "Ukrainian Medical Stomatological Academy" (HSEEU "UMUMCA"). The study involved 40 patients with an average age of 54.4 ± 3.1 years with acute exacerbation of COPD (clinical group B-C - GOLD II-III), in combination with OA. The duration of COPD was 16.2 ± 2.1 years. Among patients there were 28 (70%) men and

Almost all anxiety measurements contain somatic items that can overlap with symptoms of COPD and side effects of medicines, which can lead to bias in measuring anxiety in patients with COPD. Therefore, a brief and disease-specific non-somatic anxiety measurement scale, the Anxiety Inventory for Respiratory Disease (AIR, which has been developed and validated in its English version, is needed for patients with COPD in China.Methods: A two-center study was conducted in two tertiary hospitals in Tianjin, China. A total of 181 outpatients with COPD (mean age 67.21±8.10 years, 32.6% women, who met the inclusion and exclusion criteria, were enrolled in the study. Test–retest reliability was examined using intraclass correlation coefficients. The internal consistency was calculated by Cronbach’s α. Content validity was examined using the Content Validity Index (CVI, scale-level CVI/universal agreement, and scale-level CVI/average agreement (S-CVI/Ave. Besides, convergent validity and construct validity were also examined.Results: The AIR-C (AIR-Chinese version scale had high test–retest reliability (intraclass correlation coefficient =0.904 and internal consistency (Cronbach’s α=0.914; the content validity of the AIR-C scale was calculated by CVI, scale-level CVI/universal agreement, and S-CVI/Ave at values of 0.89–1, 0.90, and 0.98, respectively.

    Introduction: Out of all respiratory diseases COPD is the leading cause of death and is characterized with diffuse non-reversible airway obstruction. Many various components play role in development and progression of this disease, while COPD risk factors play the most prominent role. Further progress in healthcare system development around COPD in Ukraine requires analysis of legislation, regulating pulmonological medical service in Ukraine. The aim: To analyze the influence of major risk factors on the development of chronic obstructive pulmonary disease and to determine key legislative aspects of the organization of medical care for COPD patients in Ukraine. Materials and methods: 50 medical literature sources were systematically reviewed as the material for the research of COPD risk factors and their impact on studies disease. Also, an analysis of existing legislative acts regulating the pulmonological medical care in Ukraine, specifically, in patients with COPD, was conducted. Conclusions: There is a need to develop and implement a set of organizational and medical measures aiming at addressing the priorities of public healthcare, and specifically improvement of the quality of medical care for patients with chronic obstructive pulmonary disease in Ukraine.

However, many COPD patients are not diagnosed because of underrecognition or underdiagnosis of this disease among many patients and physicians. One possible reason is underrecognition of spirometry. In this study, we examined the prevalence of airflow limitation and underlying disease in patients with airflow limitation.Methodology: From April 2006 to March 2008, patients who had spirometry performed were examined. The original disease of patients, pulmonary function tests, smoking status, and respiratory symptoms were surveyed from their medical records.Results: Of all patients who had spirometry performed, 15.8% showed airflow limitation (FEV1/FVC < 0.7. A variety of diseases were observed in patients with airflow limitation. Among all diseases, cardiovascular disease was the highest and gastrointestinal malignant disease had the second highest prevalence in patients with airflow limitation.Conclusion: COPD might be frequent in conditions of comorbidity in patients treated for various diseases. Attention should be paid to the possibility of co-existence of COPD and the influence of COPD on these patients.Keywords: airflow limitation, chronic obstructive pulmonary disease, comorbidity, spirometry, prevalence

    Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Age and smoking are common risk factors for COPD and other illnesses, often leading COPD patients to demonstrate multiple coexisting comorbidities. COPD exacerbations and comorbidities contribute to the overall severity in individual patients. Clinical trials investigating the treatment of COPD routinely exclude patients with multiple comorbidities or advanced age. Clinical practice guidelines for a specific disease do not usually address comorbidities in their recommendations. However, the management and the medical intervention in COPD patients with comorbidities need a holistic approach that is not clearly established worldwide. This holistic approach should include the specific burden of each comorbidity in the COPD severity classification scale. Further, the pharmacological and nonpharmacological management should also include optimal interventions and risk factor modifications simultaneously for all diseases. All health care specialists in COPD management need to work together with professionals specialized in the management of the other major chronic diseases in order to provide a multidisciplinary approach to COPD patients with multiple diseases. In this review, we focus on the major comorbidities that affect COPD patients. We present an overview of the problems faced, the reasons and risk factors for the most commonly encountered comorbidities, and the burden on health care costs. We also provide a rationale for approaching the therapeutic options of the COPD patient afflicted by comorbidity. PMID:25609943

    Vitamin D deficiency and Chronic Obstructive Pulmonary Disease (COPD) are both under-recognized health problems, world-wide. Although Vitamin D has long been known for calcemic effects it also has less known noncalcemic effects. Recent data have shown that Vitamin D deficiency is highly prevalent in patients with COPD and correlates with forced expiratory volume in one second (FEV 1 ) and FEV 1 decline. The objective of this work was to review the current literature on vitamin D deficiency in relation with COPD. A literature search, using the words "vitamin D" and "COPD", was undertaken in Pubmed database. The noncalcemic effects of vitamin D relating with COPD may be summarised as increasing antimicrobial peptide production, regulation of inflammatory response and airway remodelling. Vitamin D inhibits the production of several proinflammatory cytokines and leads to suppression Th1 and Th17 responses which may be involved in the pathogenesis of COPD. Vitamin D insufficiency may also contribute to chronic respiratory infections and airway colonization so returning vitamin D concentrations to an optimal range in patients with COPD might reduce bacterial load and concomitant exacerbations.Vitamin D is also important for COPD-related comorbodities such as osteoporosis, muscle weakness and cardiovascular diseases. Data about the effect of Vitamin D supplementation on those comorbidities in relation with COPD are been scarce. Improving the blood level of Vitamin D into the desired range may have a beneficial effect bones and muscles, but more studies are needed to test to test that hypothesis. © 2017 John Wiley & Sons Ltd.

    The rheological properties of sputum may influence lung function and become modified in disease. This study aimed to correlate the viscoelastic properties of sputum with clinical data on the severity of disease in patients with chronic obstructive pulmonary disease (COPD). Sputum samples from COPD patients were investigated using rheology, simple mathematical modelling and Scanning Electron Microscopy (SEM). The samples were all collected from patients within two days of their admission to Prince Philip Hospital due to an exacerbation of their COPD. Oscillatory and creep rheological techniques were used to measure changes in viscoelastic properties at different frequencies over time. COPD sputum was observed to behave as a viscoelastic solid at all frequencies studied. Comparing the rheology of exacerbated COPD sputum with healthy sputum (not diagnosed with a respiratory disease) revealed significant differences in response to oscillatory shear and creep-recovery experiments, which highlights the potential clinical benefits of better understanding sputum viscoelasticity. A common power law model G(t)=G0(tτ0)-m was successfully fitted to experimental rheology data over the range of frequencies studied. A comparison between clinical data and the power law index m obtained from rheology, suggested that an important possible future application of this parameter is as a potential biomarker for COPD severity.

    Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. The outcomes of 127 COPD patients were analyzed. CAT scores (19.6±12.5 vs. 15.1±12.3) improved significantly after this program (pmanagement and the correct technique for using inhalers than those who did not have improved CAT scores (peducation program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.

    Current classifications of Chronic Obstructive Pulmonary Disease (COPD) severity are complex and do not grade levels of obstruction. Obstruction is a simpler construct and independent of ethnicity. We constructed an index of obstruction severity based on the FEV 1 /FVC ratio, with cut-points dividing the Burden of Obstructive Lung Disease (BOLD) study population into four similarly sized strata to those created by the GOLD criteria that uses FEV 1 . We measured the agreement between classifications and the validity of the FEV 1 -based classification in identifying the level of obstruction as defined by the new groupings. We compared the strengths of association of each classification with quality of life (QoL), MRC dyspnoea score and the self-reported exacerbation rate. Agreement between classifications was only fair. FEV 1 -based criteria for moderate COPD identified only 79% of those with moderate obstruction and misclassified half of the participants with mild obstruction as having more severe COPD. Both scales were equally strongly associated with QoL, exertional dyspnoea and respiratory exacerbations. Severity assessed using the FEV 1 /FVC ratio is only in moderate agreement with the severity assessed using FEV 1 but is equally strongly associated with other outcomes. Severity assessed using the FEV 1 /FVC ratio is likely to be independent of ethnicity.

    Objective To evaluate the effectiveness of an early detection program for chronic obstructive pulmonary disease (COPD) in a primary care setting in Japan. Methods Participants of ≥40 years of age who regularly visited a general practitioner's clinic due to chronic disease were asked to complete a COPD screening questionnaire (COPD Population Screener; COPD-PS) and undergo simplified spirometry using a handheld spirometric device. Patients who showed possible COPD were referred to a respiratory specialist and underwent a detailed examination that included spirometry and chest radiography. Results A total of 111 patients with possible COPD were referred for close examination. Among these patients, 27 patients were newly diagnosed with COPD. The patients with COPD were older, had lower BMI values, and had a longer smoking history in comparison to non-COPD patients. COPD patients also had more comorbid conditions. A diagnosis of COPD was significantly associated with a high COPD-PS score (pearly detection of undiagnosed COPD in primary care.

Pulmonary congestion on chest radiograph at admission for acute exacerbation of COPD (AECOPD is associated with an increased risk of mortality. A standardized evaluation of chest radiographs may enhance prognostic accuracy.Purpose: We aimed to evaluate whether a standardized, liberal assessment of pulmonary congestion is superior to the routine assessment in identifying patients at increased risk of long-term mortality, and to investigate the association of heart failure with N-terminal prohormone of brain natriuretic peptide (NT-proBNP concentrations.Material and methods: This was a prospective cohort study of 99 patients admitted for AECOPD. Chest radiographs obtained on admission were routinely evaluated and then later evaluated by blinded investigators using a standardized protocol looking for Kerley B lines, enlarged vessels in the lung apex, perihilar cuffing, peribronchial haze, and interstitial or alveolar edema, defining the presence of pulmonary congestion. Adjusted associations with long-term mortality and NT-proBNP concentration were calculated.Results: The standardized assessment was positive for pulmonary congestion in 32 of the 195 radiographs (16% ruled negative in the routine assessment. The standardized assessment was superior in predicting death during a median follow up of 1.9 years (P=0.022, and in multivariable analysis, only the standardized assessment showed a significant association with mortality (hazard ratio 2.4, 95% confidence interval [CI] 1.2–4.7 (P=0.016 and NT-proBNP (relative

    Background Little is known about the management of patients suffering from chronic obstructive pulmonary disease (COPD) during the last years of life. The aim of the study was to describe how management of COPD is performed in Sweden during the last two years of life. Methods From the nationwide Cause of Death register all individuals with COPD as the underlying cause of death during two years were identified in one sparsely and one densely populated area of Sweden. Data were collected from medical records using a pre-defined protocol, especially developed for this purpose. Results Of 822 individuals with COPD as underlying cause of death, medical records from 729 were available. The COPD diagnosis was based on lung function measurements in approximately half of the patients and median age at COPD diagnosis was 74 years (range 34-95). Women died at younger age, median 78 years (range 52-96) than did men (80 years (51-99)). The median survival time from diagnosis to death was 6 years in men and women in both areas. Among women and men 8.3% and 4.3% were never smokers, respectively. The structure of COPD management differed between the two areas, with utilization of physiotherapists, dieticians and working therapists being more used in the northern area, likely because of differences in accessibility to care institutions. Conclusions In Sweden COPD is mostly diagnosed late in life and often not verified by lung function measurements. Opposite to the general population, women with COPD die at a lower age than men.

    Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable chronic respiratory disease, which affects 210 million people globally. Global and national guidelines exist for the management of COPD. Although evidence-based, they are inadequate to address the phenotypic and genotypic heterogeneity in India. Co-existence of other chronic respiratory diseases can adversely influence the prognosis of COPD.India has a huge burden of COPD with various risk factors and comorbid conditions. However, valid prevalence estimates employing spirometry as the diagnostic tool and data on important comorbid conditions are not available. This study protocol is designed to address this knowledge gap and eventually to build a database to undertake long-term cohort studies to describe the phenotypic and genotypic heterogeneity among COPD patients in India. The primary objective is to estimate the prevalence of COPD among adults aged ≥25 years for each gender in India. The secondary objective is to identify the risk factors for COPD and important comorbid conditions such as asthma and post-tuberculosis sequelae. It is also proposed to validate the currently available definitions for COPD diagnosis in India. A cross-sectional study will be undertaken among the populations of sub-urban areas of Chennai and Shillong cities, which represent the Southern and Northeastern regions of India. We will collect data on sociodemographic variables, economic characteristics, risk factors of COPD and comorbidities. The Global Initiative for Obstructive Lung Disease (GOLD) and Global Initiative for Asthma (GINA) definitions will be used for the diagnosis of COPD and asthma. Data will be analysed for estimation of the prevalence of COPD, asthma and associated factors. This study proposal was approved by the respective institutional ethics committees of participating institutions. The results will be disseminated through publications in the peer-reviewed journals and a report

    We assessed ventricular performance during exercise in 16 chronic obstructive pulmonary disease (COPD) patients and 8 normal control subjects by means of radionuclide equilibrium angiography using technetium-99m as a tracer. Supine exercise on a bicycle ergometer was performed until symptom-limited exhaustion. Data were accumulated for 300 heart beats at rest and 150 heart beats during exercise. We used the standard voxel count method to calculate the ventricular volumes. Age, FEV{sub 1.0}%, %VC, PaO{sub 2} and PaCO{sub 2} of the COPD patients were 63{+-}8 yr, 46{+-}11%, 69{+-}18%, 68{+-}11 Torr and 44{+-}7 Torr (mean{+-}SD), respectively. Systolic dysfunction of both the left and right ventricles was well confirmed in the present study. In 12 patients who also underwent hemodynamic studies, resting total pulmonary vascular resistance index (TPVRI) and mean pulmonary artery pressure (P-barpa) significantly correlated with right ventricular end-systolic volume index (RVESVI) obtained by RI angiography; {gamma}=0.769 (p<0.01) and {gamma}=0.631 (p<0.05), respectively. A significant relationship was also observed between left ventricular dysfunction and the degree of hypercapnia. In response to exercise testing, 10 of 16 patients exhibited insufficient augmentation of stroke volume, and both left and right end-diastolic volumes decreased in half of 10 patients. It is suggested that cardiac function may be disturbed by mechanical factors such as pulmonary hyperinflation in COPD patients. (author).

    INTRODUCTION: Long-acting bronchodilators are the mainstay of pharmacological therapy for patients with chronic obstructive pulmonary disease (COPD). The choice of optimal bronchodilator therapy for COPD is increasingly difficult for clinicians as new treatments are marketed. AREAS COVERED: Inhaled...... glycopyrronium bromide (Seebri Breezhaler®) is a well-tolerated long-acting anti-muscarinic agent (LAMA) with a fast onset of action. In patients with moderate to severe COPD, glycopyrronium bromide has clinically important effects on level of FEV1, use of relief medication, day-time dyspnea scores, and probably...... also on health status. Furthermore, glycopyrronium bromide also has beneficial effects on dynamic hyperinflation and, probably by that, exercise tolerance. Glycopyrronium bromide has been shown to reduce the rate of exacerbations in patients with moderate to severe COPD, although as a secondary outcome...

    Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality worldwide. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) project has been working to improve awareness, prevention and management of this disease. The aim of this study is to evaluate how COPD patients are reclassified by the 2017 GOLD system (versus GOLD 2011), to calculate the level of agreement between these two classifications in allocation to categories and to compare the performance of each classification to predict future exacerbations. Two-hundred COPD patients (>40 years, post bronchodilator forced expiratory volume in one second/forced vital capacity<0.7) followed in pulmonology consultation were recruited into this prospective multicentric study. Approximately half of the patients classified as GOLD D [2011] changed to GOLD B [2017]. The extent of agreement between GOLD 2011 and GOLD 2017 was moderate (Cohen's Kappa = 0.511; p < 0.001) and the ability to predict exacerbations was similar (69.7% and 67.6%, respectively). GOLD B [2017] exacerbated 17% more than GOLD B [2011] and had a lower percent predicted post bronchodilator forced expiratory volume in one second (FEV1). GOLD B [2017] turned to be the predominant category, more heterogeneous and with a higher risk of exacerbation versus GOLD B [2011]. Physicians should be cautious in assessing the GOLD B [2017] patients. The assessment of patients should always be personalized. More studies are needed to evaluate the impact of the 2017 reclassification in predicting outcomes such as future exacerbations and mortality.

    Chronic obstructive pulmonary disease (COPD) is often associated with cardiovascular artery disease (CAD), representing a potential and independent risk factor for cardiovascular morbidity. Therefore, the aim of this study was to identify an algorithm for predicting the risk of CAD in COPD patients. We analyzed data of patients afferent to the Cardiology ward and the Respiratory Diseases outpatient clinic of Tor Vergata University (2010-2012, 1596 records). The study population was clustered as training population (COPD patients undergoing coronary arteriography), control population (non-COPD patients undergoing coronary arteriography), test population (COPD patients whose records reported information on the coronary status). The predicting model was built via causal relationship between variables, stepwise binary logistic regression and Hosmer-Lemeshow analysis. The algorithm was validated via split-sample validation method and receiver operating characteristics (ROC) curve analysis. The diagnostic accuracy was assessed. In training population the variables gender (men/women OR: 1.7, 95%CI: 1.237-2.5, P COPD patients, whereas in control population also age and diabetes were correlated. The stepwise binary logistic regressions permitted to build a well fitting predictive model for training population but not for control population. The predictive algorithm shown a diagnostic accuracy of 81.5% (95%CI: 77.78-84.71) and an AUC of 0.81 (95%CI: 0.78-0.85) for the validation set. The proposed algorithm is effective for predicting the risk of CAD in COPD patients via a rapid, inexpensive and non-invasive approach. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The Continuing to Confront COPD International Patient Survey estimated the prevalence and burden of COPD across 12 countries. Using data from this survey we evaluated the economic impact of COPD. This cross-sectional, population-based survey questioned 4,343 subjects aged 40 years and older, fulfilling a case definition of COPD based on self-reported physician diagnosis or symptomatology. Direct cost measures were based on exacerbations of COPD (treated and those requiring emergency department visits and/or hospitalisation), contacts with healthcare professionals, and COPD medications. Indirect costs were calculated from work loss values using the Work Productivity and Activity Impairment scale. Combined direct and indirect costs estimated the total societal costs per patient. The annual direct costs of COPD ranged from $504 (South Korea) to $9,981 (USA), with inpatient hospitalisations (5 countries) and home oxygen therapy (3 countries) being the key drivers of direct costs. The proportion of patients completely prevented from working due to their COPD ranged from 6% (Italy) to 52% (USA and UK) with 8 countries reporting this to be ≥20%. Total societal costs per patient varied widely from $1,721 (Russia) to $30,826 (USA) but a consistent pattern across countries showed greater costs among those with increased burden of COPD (symptoms, health status and more severe disease) and a greater number of comorbidities. The economic burden of COPD is considerable across countries, and requires targeted resources to optimise COPD management encompassing the control of symptoms, prevention of exacerbations and effective treatment of comorbidities. Strategies to allow COPD patients to remain in work are important for addressing the substantial wider societal costs.

    Readmission following a hospitalization for COPD is associated with significant health-care expenditure. A multicomponent COPD post-discharge integrated disease management program was implemented at the Cleveland Clinic to improve the care of patients with COPD and reduce readmissions. This retrospective study reports our experience with the program. Groups of subjects who were exposed to different components of the program were compared regarding their readmission rates. Multivariate logistic regression analysis was performed to build predictive models for 30- and 90-d readmission. One hundred sixty subjects completed a 90-d follow-up, of which, 67 attended the exacerbation clinic, 16 subjects received care coordination, 51 subjects completed both, and 26 subjects did not participate in any component despite referral. Thirty- and 90-d readmission rates for the entire group were 18.1 and 46.2%, respectively. Thirty- and 90-d readmission rates for the individual groups were: exacerbation clinic, 11.9 and 35.8%; care coordination, 25.0 and 50.0%; both, 19.6 and 41.2%; and neither, 26.9 and 80.8%, respectively. The model with the best predictive ability for 30-d readmission risk included the number of hospitalizations within the previous year and use of noninvasive ventilation (C statistic of 0.84). The model for 90-d readmission risk included receiving any component of the post-discharge integrated disease management program, the number of hospitalizations, and primary care physician visits within the previous year (C statistic of 0.87). Receiving any component of a post-discharge integrated disease management program was associated with reduced 90-d readmission rate. Previous health-care utilization and lung function impairment were strong predictors of readmission. Copyright © 2017 by Daedalus Enterprises.

    Clinical phenotyping, therapeutic investigations as well as genomic, airway secretion metabolomic and metagenomic investigations can benefit from robust, nonlinear modeling of FEV1 in individual subjects. We demonstrate the utility of measuring FEV1 dynamics in representative cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) populations. Individual FEV1 data from CF and COPD subjects were modeled by estimating median regression splines and their predicted first and second derivatives. Classes were created from variables that capture the dynamics of these curves in both cohorts. Nine FEV1 dynamic variables were identified from the splines and their predicted derivatives in individuals with CF (n = 177) and COPD (n = 374). Three FEV1 dynamic classes (i.e. stable, intermediate and hypervariable) were generated and described using these variables from both cohorts. In the CF cohort, the FEV1 hypervariable class (HV) was associated with a clinically unstable, female-dominated phenotypes while stable FEV1 class (S) individuals were highly associated with the male-dominated milder clinical phenotype. In the COPD cohort, associations were found between the FEV1 dynamic classes, the COPD GOLD grades, with exacerbation frequency and symptoms. Nonlinear modeling of FEV1 with splines provides new insights and is useful in characterizing CF and COPD clinical phenotypes.

    Exposure to nitrogen dioxide (NO 2 ) has long been linked to elevated mortality and morbidity from epidemiological evidences. However, questions remain unclear whether NO 2 acts directly on human health or being an indicator of other ambient pollutants. In this study, random-effect meta-analyses were performed on examining exposure to nitrogen oxide (NO x ) and its association with chronic obstructive pulmonary disease (COPD). The overall relative risk (RR) of COPD risk related to a 10 μg/m 3 increase in NO 2 exposure increased by 2.0%. The pooled effect on prevalence was 17% with an increase of 10 μg/m 3 in NO 2 concentration, and 1.3% on hospital admissions, and 2.6% on mortality. The RR of COPD cases related to NO 2 long-term exposure was 2.5 and 1.4% in short-term exposure. The COPD effect related with a 10 μg/m 3 increase in exposure to a general outdoor-sourced NO 2 was 1.7 and 17.8% to exposure to an exclusively traffic-sourced NO 2 ; importantly, we did observe the effect of NO 2 on COPD mortality with a large majority in lag0. Long-term traffic exerted more severe impairments on COPD prevalence than long-term or short-term outdoor effect; long-term mortality effect on COPD was serious in single model from this meta-analysis. Overall, our study reported consistent evidence of the potential positive association between NO 2 and COPD risk.

    Objective Osteoporosis, which is now recognized as a major comorbidity of chronic obstructive pulmonary disease (COPD), must be diagnosed by appropriate methods. The aims of this study were to clarify the relationships between bone mineral density (BMD) and COPD-related clinical variables and to explore the association of BMD with the updated Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification in men. Methods We enrolled 50 Japanese men with clinically stable COPD who underwent dual-energy X-ray absorptiometry (DEXA), pulmonary function testing, and computerized tomography (CT) and who had completed a questionnaire (COPD assessment test [CAT]). We determined the association between the T-score and other tested parameters and compared the BMD of patients in each GOLD category. Results Twenty-three of the 50 patients (46.0%) were diagnosed with osteopenia, and 7 (14.0%) were diagnosed with osteoporosis. The BMD findings were significantly correlated with the CAT score, forced expiratory volume in 1 second percentage predicted (FEV 1 % predicted), low attenuation volume percentage (LAV%), and percentage of cross-sectional area of small pulmonary vessels (%CSA) on CT images. Notably, the median T-score of the GOLD category D participants was significantly lower than that of the participants in each of the other categories (A [-0.98], B [-1.06], C [-1.05], and D [-2.19], pCOPD. The BMD of GOLD category D patients was the lowest of all of the patients evaluated, and category D patients may benefit from active intervention for osteoporosis.

    This study aimed to increase our understanding of general self-management (SM) abilities in COPD by determining if SM can predict disease specific quality of life (QoL), by investigating whether specific SM domains are significant in COPD and by exploring the mediating effect of the positive/negative affect in the association between SM and QoL. Cross-sectional study based on 292 patients with COPD. Measures included demographics, lung function, gait speed, health care utilization, positive/negative affect, SM abilities, breathlessness and disease specific QoL. We performed, correlation, multiple regression models and mediation analysis (positive/negative affect being mediator between SM and QoL association). After controlling for breathlessness, living alone, marital status, hospitalization history, age and lung function, SM related to QoL (pnegative affect ratio completely mediates the relationship of SM with QoL. SM is independently associated with disease specific QoL in COPD after adjustment significant covariates but positive/negative affect ratio completely mediates the relationship of SM with QoL. Measuring positive/negative affect and addressing investment behavior and self-efficacy are important in implementing COPD-SM programs. Copyright © 2015 The Authors.

Although the efficacy of LAMAs and LABAs has been well established through randomized controlled trials (RCTs, questions remain regarding their cardiovascular (CV safety. Furthermore, while the safety of LAMA and LABA monotherapy has been extensively studied, data are lacking for LAMA/LABA combination therapy, and the majority of the studies that have reported on the CV safety of LAMA/LABA combination therapy were not specifically designed to assess this. Evaluation of CV safety for COPD treatments is important because many patients with COPD have underlying CV comorbidities. However, severe CV and other comorbidities are often exclusion criteria for RCTs, contributing to a lack in external validity and generalizability. Real-world observational studies are another important tool to evaluate the effectiveness and safety of COPD therapies in a broader population of patients and can improve upon the external validity limitations of RCTs. We examine what is already known regarding the CV and cerebrovascular safety of LAMA/LABA combination therapy from RCTs and real-world observational studies, and explore the advantages and

    Malnutrition is a comorbidity oftenly seen in COPD patients who have progressive chronic inflammation and severity. In this prospective study, we aimed to determine the nutritional status of stable COPD patients and to investigate the impact of nutritional status on perception of dyspnoea, exercise capacity, body composition, hospitalisation and life quality. COPD patients were assessed using previous smoking story, physical examination and irreversible airway obstruction. This study was done with 50 COPD patients older than 65 years of age and 30 control subjects. Exclusion criteria were also the co-existance of malignancies, malabsorbtion, DM, neurological diseases, renal failure and unstable cardiac diseases known to influence the nutritional state. The obstruction degree was evaluated by spirometry, nutritional status was classified by the MNA questionnaire, perception of dyspnoea was assessed by the MMRC scale, exercise capacity was assessed by the 6MWT, life quality was assessed by the CAT scale. Body composition parameters FM, FFM and FMI were analyzed and hospitalisations during 6 months after discharge were recorded. The COPD patients were divided into three groups as without malnutrition (n= 25,%50), under risk of malnutrition (n= 19,%38) and malnourished (n= 6,%12). The COPD severity, MMRC dyspnoea score, CAT score and hospitalisations during 6 months following were higher among the malnourished patients. On the other hand, body mass index, 6MWT results, FM and FFM were lower in malnourished patients. A positive correlation between FFM and 6MWT and a negative correlation between FFM and hospitalisation were observed. MNA is a well-developed questionnaire which evaluates malnutrition in COPD patients. We determined that malnourished COPD patients have higher airway obstruction degree, perception of dyspnoea, CAT score and lower exercise capacity and FFM. FFM is an independent predictor of exercise capacity and rehospitalisation during 6 months.

    Full Text Available Collaboration between patients and their medical and technical experts enabled the development of an automated questionnaire for the early detection of COPD exacerbations (AQCE. The questionnaire consisted of fourteen questions and was implemented on a computer system for use by patients at home in an un-supervised environment. Psychometric evaluation was conducted after a 6-month field trial. Fifty-two patients were involved in the development of the questionnaire. Reproducibility was studied using 19 patients (ICC = 0.94. Sixteen out of the 19 subjects started the 6 month-field trial with the computer application. Cronbach’s alpha of 0.81 was achieved. In the concurrent validity analysis, a correlation of 0.80 (p = 0.002 with the CCQ was reported. The results suggest that AQCE is a valid and reliable questionnaire, showing that an automated home-based electronic questionnaire may enable early detection of exacerbations of COPD.

    Full Text Available Konstantinos Kostikas, Andreas Clemens, Francesco Patalano Novartis Pharma AG, Basel, Switzerland Abstract: The term asthma–COPD overlap syndrome (ACOS is one of multiple terms used to describe patients with characteristics of both COPD and asthma, representing ~20% of patients with obstructive airway diseases. The recognition of both sets of morbidities in patients is important to guide practical treatment decisions. It is widely recognized that patients with COPD and coexisting asthma present with a higher disease burden, despite the conceptual expectation that the “reversible” or “treatable” component of asthma would allow for more effective management and better outcomes. However, subcategorization into terms such as ACOS is complicated by the vast spectrum of heterogeneity that is encapsulated by asthma and COPD, resulting in different clinical clusters. In this review, we discuss the possibility that these different clusters are suboptimally described by the umbrella term “ACOS”, as this additional categorization may lead to clinical confusion and potential inappropriate use of resources. We suggest that a more clinically relevant approach would be to recognize the extreme variability and the numerous phenotypes encompassed within obstructive airway diseases, with various degrees of overlapping in individual patients. In addition, we discuss some of the evidence to be considered when making practical decisions on the treatment of patients with overlapping characteristics between COPD and asthma, as well as the potential options for phenotype and biomarker-driven management of airway disease with the aim of providing more personalized treatment for patients. Finally, we highlight the need for more evidence in patients with overlapping disease characteristics and to facilitate better characterization of potential treatment responders.

    Adverse health effects have been associated with urban pollutant exposure arising from close proximity to highly-emitting sources and atmospheric mixing. The relative air pollution exposure dose and time effects on various diseases remains unknown. This study compares the increased risk of health complications when patients are exposed to short term high-levels of air pollution vs. longer term exposure to lower levels of air pollution. We used the electronic medical record of an integrated hospital system based in Utah, Intermountain Healthcare, to identify a cohort of patients with Chronic Obstructive Pulmonary Disease (COPD) who were seen between 2009-2014. We determined patient demographics as well as comorbidity data and healthcare utilization. To determine the approximate air pollution dose and time exposure, we used the Hestia highly-resolved emissions inventory for Salt Lake County, Utah in conjunction with emissions based on the National Emissions Inventory (NEI). Hourly emissions of CO2 and criteria air pollutants were gridded at a 0.002o x 0.002o resolution for the study years. The resulting emissions were transported using the CALPUFF and AERMOD dispersion models to estimate air pollutant concentrations at an hourly 0.002o x 0.002oresolution. Additionally, pollutant concentrations were estimated at each patient's home and work address to estimate exposure. Multivariate analysis adjusting for patient demographics, comorbidities and severity of COPD was performed to determine association between air pollution exposure and the risk of hospitalization or emergency department (ED) visit for COPD exacerbation and an equivalency estimate for air pollution exposure was developed. We noted associations with air pollution levels for each pollutant and hospitalizations and ED visits for COPD and other patient comorbidities. We also present an equivalency estimate for dose of air pollution exposure and health outcomes. This analysis compares the increased risk of

    Cigarette smoking is a major public health problem, which leads to the formation of chronic obstructive pulmonary disease (COPD) and is one of the main causes of avoidable death and disability worldwide. The aim of study was analysis and comparison of the visceral fat in the body of the three groups of subjects (non-smokers, smokers and COPD patients) by Tanita Viscan 140. The control group was composed of: (1) non-smokers (n=30), consisted of 13 males (43.4%) and 17 women (56.6%) - the average age was 52 ± 6.51 years and (2) smokers (n=30), consisted of 12 men (40%) and 18 women (60%) - the average age 46.53 ± 9.22 years. Study group consisted of patients with COPD (n=60), which consisted of 48 men (80%) and 12 women (20%). Mean age was 69.25 ± 9.90 years. The measurement of visceral fat by Tanita Viscan device 140, which uses bioelectrical impedance analysis to measure fat in the abdomen of the patient in the supine position. High levels of visceral fat (women from 36.9% to 52.3% and more, men from 27.1% to 40.3% or more) were observed in 19 patients (3 women and 16 men), with 19 smokers (10 women and 9 men) and non-smokers in 22 subjects (10 women and 12 men). The average value of waist circumference measured with a Tanita Viscan 140 was in the group of patients 96.38 ± 12.27 cm, in the group of smokers 95.23 ± 10.12 cm and in group of non-smokers 96.86 ± 10.88 cm. The results of our work are of great importance for the health assessment not only among patients with COPD but also in the group of smokers. Therefore it would be appropriate to remind the general public, eg. by campaign for chronic obstructive pulmonary disease and its serious complications and reduce the life quality of these patients and thus help protect human health and in particular young people from the harmful effects of tobacco products.

    Full Text Available Objective: To assess sub-clinical cognitive dysfunctions in stable chronic obstructive pulmonary disease (COPD patients having no hypoxemia vs. age-matched healthy volunteers using (i an electrophysiological test: Auditory event related potential, P300 test and (ii a questionnaire tool: Mini-mental state examination (MMSE questionnaire. Materials and Methods: Eighty male subjects were included: 40 stable COPD patients (smoking history >20 pack years and 40 healthy volunteers (HVs. Age, duration of illness, smoking pack years, and spirometric indices were assessed. MMSE scores were evaluated in these groups. Latency of P300 wave and amplitude of P300 wave were studied in both groups to detect P300 abnormalities in COPD group. Correlations of P300 abnormalities with patient characteristic parameters and MMSE scores were assessed. In addition, individual COPD patients having significant cognitive dysfunctions beyond cut-off value of 99 th percentile of HVs were analyzed. Results: We observed significantly prolonged P300 latency ( P 0.05 for all. Conclusions: Our study explores cognitive dysfunctions in stable COPD patients with no hypoxemia. This study highlights the relative importance of using MMSE and P300. Cognitive dysfunctions were detected both by MMSE and P300; however, MMSE abnormalities were more frequent compared to P300 abnormalities (27/40 vs. 10/40 in COPD patients.

    Chronic obstructive pulmonary disease (COPD) and chronic heart failure (HF) are common clinical conditions that share tobacco as a risk factor. Our aim was to evaluate the prognostic impact of COPD on HF patients. The Norwegian Heart Failure Registry was used. The study included 4132 HF patients (COPD, n = 699) from 22 hospitals (mean follow-up, 13.3 months). COPD patients were older, more often smokers and diabetics, less often on beta-blockers and had a higher heart rate. They were more often in New York Heart Association (NYHA) Class III or IV (COPD, 63%; no COPD, 51%), although left ventricular ejection fraction (LVEF) distribution was similar. COPD independently predicted death (adjusted hazard ratio [HR], 1.188; 95% CI: 1.015 to 1.391; P = 0.03) along with age, creatinine, NYHA Class III/IV (HR, 1.464; 95% CI: 1.286 to 1.667) and diabetes. beta-blockers at baseline were associated with improved survival in patients with LVEF < or =40% independently of COPD. COPD is associated with a poorer survival in HF patients. COPD patients are overrated in terms of NYHA class in comparison with patients with similar LVEF. Nonetheless, NYHA class remains the strongest predictor of death in these patients. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    Chronic obstructive pulmonary disease (COPD) is a common disease that leads to huge economic and social burden. Efficient and effective management of stable COPD is essential to improve quality of life and reduce medical expenditure. The Internet of Things (IoT), a recent breakthrough in communication technology, seems promising in improving health care delivery, but its potential strengths in COPD management remain poorly understood. We have developed a mobile phone-based IoT (mIoT) platform and initiated a randomized, multicenter, controlled trial entitled the ‘MIOTIC study’ to investigate the influence of mIoT among stable COPD patients. In the MIOTIC study, at least 600 patients with stable GOLD group C or D COPD and with a history of at least two moderate-to-severe exacerbations within the previous year will be randomly allocated to the control group, which receives routine follow-up, or the intervention group, which receives mIoT management. Endpoints of the study include (1) frequency and severity of acute exacerbation; (2) symptomatic evaluation; (3) pre- and post-bronchodilator forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) measurement; (4) exercise capacity; and (5) direct medical cost per year. Results from this study should provide direct evidence for the suitability of mIoT in stable COPD patient management. PMID:24082784

    Lung transplantation is commonly used for patients with end-stage lung disease. However, there is continuing debate on the optimal operation for patients with chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. Single-lung transplantation (SLT) provides equivalent short- and medium-term results compared with bilateral lung transplantation (BLT), but long-term survival appears slightly better in BLT recipients (especially in patients with COPD). The number of available organs for lung transplantation also influences the choice of operation. Recent developments suggest that the organ donor shortage is not as severe as previously thought, making BLT a possible alternative for more patients. Among the different complications, re-implantation edema, infection, rejection, and bronchial complications predominate. Chronic rejection, also called obliterative bronchiolitis syndrome, is a later complication which can be observed in about half of the patients. Improvement in graft survival depends greatly in improvement in prevention and management of complications. Despite such complications, graft survival in fibrosis patients is greater than spontaneous survival on the waiting list; idiopathic fibrosis is associated with the highest mortality on the waiting list. Patients should be referred early for the pre-transplantation work-up because individual prognosis is very difficult to predict.

  12. How to adapt the pulmonary rehabilitation programme to patients with chronic respiratory disease other than COPD

    Full Text Available Dyspnoea, fatigue, reduced exercise tolerance, peripheral muscle dysfunction and mood disorders are common features of many chronic respiratory disorders. Pulmonary rehabilitation successfully treats these manifestations in chronic obstructive pulmonary disease (COPD and emerging evidence suggests that these benefits could be extended to other chronic respiratory conditions, although adaptations to the standard programme format may be required. Whilst the benefits of exercise training are well established in asthma, pulmonary rehabilitation can also provide evidence-based interventions including breathing techniques and self-management training. In interstitial lung disease, a small number of trials show improved exercise capacity, symptoms and quality of life following pulmonary rehabilitation, which is a positive development for patients who may have few treatment options. In pulmonary arterial hypertension, exercise training is safe and effective if patients are stable on medical therapy and close supervision is provided. Pulmonary rehabilitation for bronchiectasis, including exercise training and airway clearance techniques, improves exercise capacity and quality of life. In nonsmall cell lung cancer, a comprehensive interdisciplinary approach is required to ensure the success of pulmonary rehabilitation following surgery. Pulmonary rehabilitation programmes provide important and underutilised opportunities to improve the integrated care of people with chronic respiratory disorders other than COPD.

    Full Text Available Despite the overwhelming evidence justifying the use of non-invasive ventilation (NIV for providing ventilatory support in chronic obstructive pulmonary disease (COPD exacerbations, recent studies demonstrated that its application in real-life settings remains suboptimal. European clinical audits have shown that 1 NIV is not invariably available, 2 its availability depends on countries and hospital sizes, and 3 numerous centers declare their inability to provide NIV to all of the eligible patients presenting throughout the year. Even with an established indication, the use of NIV in acute respiratory failure due to COPD exacerbations faces important challenges. First, the location and personnel using NIV should be carefully selected. Second, the use of NIV is not straightforward despite the availability of technologically advanced ventilators. Third, NIV therapy of critically ill patients requires a thorough knowledge of both respiratory physiology and existing ventilatory devices. Accordingly, an optimal team-training experience, the careful selection of patients, and special attention to the selection of devices are critical for optimizing NIV outcomes. Additionally, when applied, NIV should be closely monitored, and endotracheal intubation should be promptly available in the case of failure. Another topic that merits careful consideration is the use of NIV in the elderly. This patient population is particularly fragile, with several physiological and social characteristics requiring specific attention in relation to NIV. Several other novel indications should also be critically examined, including the use of NIV during fiberoptic bronchoscopy or transesophageal echocardiography, as well as in interventional cardiology and pulmonology. The present narrative review aims to provide updated information on the use of NIV in acute settings to improve the clinical outcomes of patients hospitalized for COPD exacerbations.

    Some patients with chronic obstructive pulmonary disease (COPD) fail to achieve health benefits with pulmonary rehabilitation (PR). Exercise intensity and load represent stimulus for adaptation but it is unclear whether inappropriate exercise intensity and/or load are affected by severity of COPD, which may affect health benefits. The purpose was to determine whether COPD severity and/or the severity of pulmonary limitation to exercise (PLE) impacted exercising intensity or load and whether resultant intensity/load affected health outcomes derived from PR. Patients with COPD (n = 58, age = 67 ± 7 y, forced expiratory volume in the first second of expiration [FEV1] % predicted = 52 ± 21%) were recruited upon referral to PR. Primary health outcomes evaluated were 6-min walk distance and St George's Respiratory Questionnaire. Patients were stratified for disease severity using Global Initiative for Obstructive Lung Disease (GOLD) staging and PLE severity by change in inspiratory capacity during exercise. Exercise intensity and load were calculated from daily exercise records. Participants achieved comparable training duration and load regardless of GOLD severity. Patients with more severe PLE achieved greater training duration (more severe: 546 ± 143 min., less severe: 451 ± 109 min., P = .036), and relative training load (more severe: 2200.8 ± 595.3 kcal, less severe: 1648.3 ± 597.8 kcal, P = .007). Greater overall training load was associated with greater improvements in 6-min walk distance (r = 0.24, P = .035). No significant relationships were observed between PLE, GOLD severity, training parameters, and St George's Respiratory Questionnaire response. Improvements in exercise tolerance can be explained by achieving greater training loads, demonstrating the importance of appropriate training load to maximize health outcomes in PR.

    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 AND 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.

    Elucidating the prevalence of asthma and chronic obstructive pulmonary disease (COPD) is important for designing a public health strategy. Recent studies have discriminated a phenotype of COPD with variable airflow limitation (COPD-VAL) associated with asthma-COPD overlap syndrome. Its prevalence remains uncertain. The age and occupational distributions in the town of Hisayama and in Japan are nearly identical. Each disease's prevalence was estimated for the town's residents. In 2008, town residents (≥ 40 years) were solicited to participate in a health checkup. Individuals with abnormal spirometry (forced expiratory volume in 1s/forced vital capacity [FEV1/FVC]fashion reviewed their medical records, including bronchodilator reversibility. Individuals with airflow limitation were classified as having asthma, COPD, COPD-VAL, or other diseases. The prevalence of each disease was then estimated. A total of 2100 residents (43.4% of residents in the age group) completed spirometry. In 455 residents with abnormal spirometry, 190 residents had further evaluations, and the medical records of 174 residents were reviewed. The prevalence of asthma with airflow limitation, COPD, and COPD-VAL, were 2.0%, 8.4%, and 0.9%, respectively. The prevalence of COPD and COPD-VAL were higher in men and smokers than in women and never-smokers. The prevalence of COPD, but not COPD-VAL or asthma, increased with age. The prevalence of asthma with airflow limitation, COPD, and COPD-VAL were estimated in a population of residents (≥ 40 years) in Hisayama. Copyright © 2014 The Japanese Respiratory Society.

    Chronic obstructive pulmonary disease (COPD) is an airway inflammatory disease caused by inhalation of toxic particles, mainly cigarette smoking, and now is accepted as a disease associated with systemic characteristics. The aim of this work was to investigate and compare selected biochemical parameters in patients with and without COPD. Observation group consisted of clinically stable patients with COPD (n = 60). The control group was healthy persons from the general population, without COPD, who were divided into two subgroups – smokers (n = 30) and non-smokers (n = 30). Laboratory parameters were investigated by automated clinical chemistry analyzer LISA 200th. Albumin in our measurements showed an average value of 39.55 g.l-1 in the patient population; 38.89 g.l-1 in smokers and in non-smokers group 44.65 g.l-1. The average value of pre-albumin in the group of patients was 0.28 ± 0.28 g.l-1 and 0.30 ± 0.04 g.l-1 in smokers group. The average value of the orosomucoid in patients was about 1.11 ± 0.90 mg.ml-1. In the group of smokers, the mean value of orosomucoid was 0.60 ± 0.13 mg.ml-1. The level of C-reactive protein (CRP) in the patient group reached an average value of 15.31 ± 22.04 mg.l-1, in the group of smokers was 5.18 ± 4.58 mg. l-1. Prognostic inflammatory and nutritional index (PINI) in the group of patients showed a mean value of 4.65 ± 10.77 and 0.026 ± 0.025 in smokers. The results of this work show, that the values of index PINI in COPD patients are significantly higher than in smokers (P COPD.

    Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death globally. In addition to the mortality associated with it, people with COPD experience significant morbidity, making this set of conditions a major public health concern. Infections caused by influenza virus are a preventable cause of morbidity and vaccination has been shown to be effective. The evidence of their benefit in persons with COPD mainly comes from high-income countries where influenza vaccination is used in routine practice, but little is known about the effectiveness, cost-effectiveness, and scalability of vaccination in low- and middle-income countries. We therefore systematically reviewed and present evidence related to vaccination against influenza in persons with COPD with a special focus on studies from low- and middle-income countries (LMICs). Available data from 19 studies suggest that the use of influenza vaccine in persons with COPD is beneficial, cost-effective, and may be relevant for low- and middle-income countries. Wider implementation of this intervention needs to take into account the health care delivery systems of LMICs and use of prevalent viral strains in vaccines to be most cost effective.

    Introduction. Multi-resistant Acinetobacter baumannii isolated from patients has become one of the most hazardous pathogens in health care settings. The aim of the study was to analyze pneumonia caused by Acinetobacter baumannii in patients hospitalized because of exacerbation of chronic obstructive pulmonary diseases (COPD), who were admitted to the Pulmonology Ward of the Masovian Specialistic Hospital in Radom (MSS). The incidence and drug sensitivity of these non-fermenting rods were evaluated, and compliance with antimicrobial procedure with the algorithm of the guidelines in applicable recommendations, was estimated. This should result in determining the local patterns of resistance and verifying therapeutic procedures in accordance with the assumptions of hospital antibiotic policy. In addition, the study examined the effectiveness of empiric and targeted therapy according to the clinical condition of the patient, and the eradication of A. baumannii, in comparison with the aggravating factors of the patient. Materials and Method. The retrospective study included 90 patients with exacerbation of COPD whose etiological factor of infection was A. baumannii, hospitalized in the Department of Pulmonology (MSS) in 2012-2016. Results. Studies were conducted on 90 patients with COPD exacerbation from which A. baumannii was isolated. Co-infections with other bacterial species among 41 patients were additionally noted. The majority of A. baumannii strains showed a high resistance (90%) to fluoroquinolones, ceftazidime, piperacillin/tazobactam. For strains causing a co-infection, drug resistance was successively 44-56%, 44%, 44%. All of patients received empirical therapy. The most commonly used drug was amoxicillin with a clavulanic acid, often combined with fluoroquinolone. This type of therapy was effective among 10% of patients. The mortality in this group was determined at 29%. Among 79% of patients with COPD, a targeted therapy was performed which proved to be

    Chronic obstructive pulmonary disease (COPD) is a leading and costly cause of readmissions to the hospital, with one of the highest rates reported in Florida. From 2009 to 2014, strategies such as readmission reduction programs, as well as updated guidelines for COPD management, were instituted to reduce readmission rates for patients with COPD. Thus, the question has been raised whether COPD-related 30-day hospital readmission rates in Florida have decreased and whether COPD-related readmission costs during this period have changed. In addition, we examined trends in length of stay, hospital charges, and in-hospital mortality associated with COPD, as well as identified patient-level risk factors associated with 30-day readmissions. A retrospective analysis of adult patients (≥18 years of age) with COPD was conducted by using the Healthcare Cost and Utilization Project Florida State Inpatient Database, 2009 to 2014. Weighted least squares regression was used to assess trends in the COPD readmission rate on a yearly basis, as well as other outcomes of interest. A multivariable logistic regression was used to identify patient characteristics that were associated with 30-day COPD readmissions. Overall, 268,084 adults were identified as having COPD. Between 2009 and 2014, more than half of patients aged 65-84 years, most were white, 55% were female, and 73% had Medicare. The unadjusted rate for COPD-related 30-day readmissions did not change (8.04% to 7.85%; P = 0.434). However, the mean total charge for 30-day COPD-related readmissions was significantly higher in 2014 ($40,611) compared with that in 2009 ($36,714) (P = 0.011). The overall unadjusted in-hospital mortality of COPD-related hospitalizations significantly decreased from 1.83% in 2009 to 1.34% in 2014 (P COPD were 2% less likely to be readmitted to the hospital for each additional year (odds ratio [OR], 0.98 [95% confidence interval (CI), 0.97-0.99]).

    Up to half of all smokers develop clinically significant chronic obstructive pulmonary disease (COPD). Gaps exist in the implementation and uptake of evidence-based guidelines for managing COPD in primary care. We describe the methodology of a cluster randomised controlled trial (cRCT) evaluating the efficacy and cost-effectiveness of an interdisciplinary model of care aimed at reducing the burden of smoking and COPD in Australian primary care settings. A cRCT is being undertaken to evaluate an interdisciplinary model of care (RADICALS - Review of Airway Dysfunction and Interdisciplinary Community-based care of Adult Long-term Smokers). General practice clinics across Melbourne, Australia, are identified and randomised to the intervention group (RADICALS) or usual care. Patients who are current or ex-smokers, of at least 10 pack years, including those with an existing diagnosis of COPD, are being recruited to identify 280 participants with a spirometry-confirmed diagnosis of COPD. Handheld lung function devices are being used to facilitate case-finding. RADICALS includes individualised smoking cessation support, home-based pulmonary rehabilitation and home medicines review. Patients at control group sites receive usual care and Quitline referral, as appropriate. Follow-ups occur at 6 and 12 months from baseline to assess changes in quality of life, abstinence rates, health resource utilisation, symptom severity and lung function. The primary outcome is change in St George's Respiratory Questionnaire score of patients with COPD at 6 months from baseline. This project has been approved by the Monash University Human Research Ethics Committee and La Trobe University Human Ethics Committee (CF14/1018 - 2014000433). Results of the study will be disseminated in peer-reviewed journals and research conferences. If the intervention is successful, the RADICALS programme could potentially be integrated into general practices across Australia and sustained over time. ACTRN

    Few studies to date have investigated the antioxidant nutrients such as vitamin C (ascorbic acid), vitamin E (α-tocopherol), retinol and carotenoids in plasma from patients with pulmonary disease in Japan. To clarify the role of antioxidant nutrients such as vitamin C, vitamin E, retinol and various carotenoids in plasma of Japanese patients with chronic obstructive lung diseases (COPD), asthma-COPD overlap syndrome (ACOS) and/or bronchial asthma (BA), we compared to healthy elderly controls. Ascorbic acid (AA), carotenoids (lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene and lycopene), retinol and α-tocopherol levels in plasma were determined by using a high performance liquid chromatography. Reduced glutathione (GSH), oxidised glutathione (GSSG) in whole blood and urinary 8-OHdG were also determined. Plasma AA level of COPD subjects was significantly lower than that of healthy elderly people. Conversely, ACOS and BA subjects showed no significant difference from healthy elderly people. Moreover, plasma lycopene and total carotenoid levels and GSH content in blood were significantly lower in COPD subjects than these in healthy elderly people. However, other redox markers such as GSSG, GSH/GSSG ratio and urinary 8-OHdG found no significant differences between COPD, ACOS and BA compared to healthy elderly people. These results suggested that COPD of Japanese patients may develop partly because of oxidative stress derived from a shortage of antioxidant nutrients, especially of AA and lycopene, as well as GSH while this may not be the case in both ACOS and BA. © 2016 John Wiley & Sons Ltd.

    Full Text Available Exhaled volatile organic compounds (VOCs are of interest for their potential to diagnose disease non-invasively. However, most breath VOC studies have analyzed single breath samples from an individual and assumed them to be wholly consistent representative of the person. This provided the motivation for an investigation of the variability of breath profiles when three breath samples are taken over a short time period (two minute intervals between samples for 118 stable patients with Chronic Obstructive Pulmonary Disease (COPD and 63 healthy controls and analyzed by gas chromatography and mass spectroscopy (GC/MS. The extent of the variation in VOC levels differed between COPD and healthy subjects and the patterns of variation differed for isoprene versus the bulk of other VOCs. In addition, machine learning approaches were applied to the breath data to establish whether these samples differed in their ability to discriminate COPD from healthy states and whether aggregation of multiple samples, into single data sets, could offer improved discrimination. The three breath samples gave similar classification accuracy to one another when evaluated separately (66.5% to 68.3% subjects classified correctly depending on the breath repetition used. Combining multiple breath samples into single data sets gave better discrimination (73.4% subjects classified correctly. Although accuracy is not sufficient for COPD diagnosis in a clinical setting, enhanced sampling and analysis may improve accuracy further. Variability in samples, and short-term effects of practice or exertion, need to be considered in any breath testing program to improve reliability and optimize discrimination.

    Smoking is the main cause of COPD, a chronic non-curable lung disease. Not all smokers develop COPD and it is still unclear why COPD is only manifested in a small subset of smokers (15-20%). Probably their genetic background makes the difference. We investigated whether young individuals (18-40

    Many people living with Chronic Obstructive Pulmonary Disease (COPD) have low general health literacy; however, there is little information available on these patients' eHealth literacy, or their ability to seek, find, understand, and appraise online health information and apply this knowledge to address or solve disease-related health concerns. A nationally representative sample of patients registered in the COPD Foundation's National Research Registry (N = 1,270) was invited to complete a web-based survey to assess socio-demographic (age, gender, marital status, education), health status (generic and lung-specific health-related quality of life), and socio-cognitive (social support, self-efficacy, COPD knowledge) predictors of eHealth literacy, measured using the 8-item eHealth literacy scale (eHEALS). Over 50% of the respondents (n = 176) were female (n = 89), with a mean age of 66.19 (SD = 9.47). Overall, participants reported moderate levels of eHealth literacy, with more than 70% feeling confident in their ability to find helpful health resources on the Internet. However, respondents were much less confident in their ability to distinguish between high- and low-quality sources of web-based health information. Very severe versus less severe COPD (β = 4.15), lower lung-specific health-related quality of life (β = -0.19), and greater COPD knowledge (β = 0.62) were significantly associated with higher eHealth literacy. Higher COPD knowledge was also significantly associated with greater knowledge (ρ = 0.24, p = .001) and use (ρ = 0.24, p = .001) of web-based health resources. Findings emphasize the importance of integrating skill-building activities into comprehensive patient education programs that enable patients with severe cases of COPD to identify high-quality sources of web-based health information. Additional research is needed to understand how new social technologies can be used to help medically underserved COPD patients

    Knowledge about the prevalence of objectively assessed peripheral artery disease (PAD) and its clinical relevance in patients with chronic obstructive pulmonary disease (COPD) is scarce. We aimed to: (1) assess the prevalence of PAD in COPD compared with distinct control groups; and (2) study the association between PAD and functional capacity as well as health status. The ankle-brachial index was used to diagnose PAD (ankle-brachial index ≤ 0.9). The 6-minute-walk distance, health status (St. George's Respiratory Questionnaire), COPD Assessment Test, and EuroQol-5-Dimensions were assessed in patients enrolled in the German COPD and Systemic Consequences-Comorbidities Network cohort study. Control groups were derived from the Study of Health in Pomerania. A total of 2,088 patients with COPD (61.1% male; mean [SD] age, 65.3 [8.2] years, GOLD (Global Initiative for Chronic Obstructive Lung Disease) stages I-IV: 9.4, 42.5, 37.5, and 10.5%, respectively) were included, of which 184 patients (8.8%; GOLD stage I-IV: 5.1, 7.4, 11.1, and 9.5%, respectively, vs. 5.9% in patients with GOLD stage 0 in the COPD and Systemic Consequences-Comorbidities Network) had PAD. In the Study of Health in Pomerania, PAD ranged from 1.8 to 4.2%. Patients with COPD with PAD had a significantly shorter 6-minute-walk distance (356 [108] vs. 422 [103] m, P COPD Assessment Test: 19.6 [7.4] vs. 17.9 [7.4] points, P = 0.004; EuroQol-5-Dimensions visual analog scale: 51.2 [19.0] vs. 57.2 [19.6], P COPD, 8.8% were diagnosed with PAD, which is higher than the prevalence in control subjects without COPD. PAD was associated with a clinically relevant reduction in functional capacity and health status.

    Extending palliative care to those with advanced non-malignant disease is advocated, but the implications in specific conditions are poorly understood. We piloted a novel nurse-led intervention, HELPing older people with very severe chronic obstructive pulmonary disease (HELP-COPD), undertaken 4 weeks after discharge from hospital, which sought to identify and address the holistic care needs of people with severe COPD. This 6-month mixed-method feasibility pilot trial randomised (ratio 3:1) patients to HELP-COPD or usual care. We assessed the feasibility of using validated questionnaires as outcome measures and analysed the needs/actions recorded in the HELP-COPD records. Semi-structured interviews with a purposive sample of patients, carers and professionals explored the perceptions of HELP-COPD. Verbatim transcriptions and field notes were analysed using Normalisation Process Theory as a framework. We randomised 32 patients (24 to HELP-COPD); 19 completed the study (death=3, ill-health=4, declined=6). The HELP-COPD record noted a mean of 1.6 actions/assessment, mostly provision of information or self-help actions: only five referrals were made. Most patients were positive about HELP-COPD, discussing their concerns and coping strategies in all domains, but the questionnaires were burdensome for some patients. Adaptation to their slowly progressive disability and a strong preference to rely on family support was reflected in limited acceptance of formal services. Professionals perceived HELP-COPD as addressing an important aspect of care, although timing overlapped with discharge planning. The HELP-COPD intervention was well received by patients and the concept resonated with professionals, although delivery post discharge overlapped with existing services. Integration of brief holistic care assessments in the routine primary care management of COPD may be more appropriate.

    Individuals with chronic obstructive pulmonary disease (COPD) exhibit low physical and mental health-related quality of life (HRQL) and high susceptibility to disability. We investigated the influence of psychological factors on HRQL and disability in COPD individuals recruited from the general population. In line with Leventhal's common sense model, we expected psychological factors to be associated with HRQL and disability even after controlling for medical status. Individuals with COPD (n = 502; 59.7 years old; GOLD grades were I: 3%, II: 17%, III: 34%, IV: 46%) were assessed through an online survey administered via COPD patient organisations in Germany. Individuals filled in the Short Form Health Survey (SF-12), COPD Assessment Test, Patient Health Questionnaire (modules: GAD-2, PHQ-15, PHQ-9), Brief Illness Perception Questionnaire, a questionnaire that assesses causal illness attributions, and the internal illness-related locus of control scale of the 'KKG questionnaire for the assessment of control beliefs about illness and health'. Multiple linear regressions were calculated. The investigated factors explained high variances (disability = 56%, physical HRQL = 28%, mental HRQL = 63%, p ≤ .001). Better mental health, more optimistic illness perceptions, attribution to psychological causes, and stronger internal locus of control were associated with lower disability and better HRQL. Comorbid somatic symptoms contributed to high disability and low quality of life. Psychological factors, such as illness perception, attribution and internal locus of control, were associated with disability and HRQL. These factors should be considered when designing treatments for individuals with COPD, and adequate interventions should be provided to enhance illness understanding and self-management skills.

    Chronic obstructive pulmonary disease (COPD) is characterized by chronic incompletely reversible poor airflow and air trapping and usually this debilitating disorder limits the outside activities of the patients depriving them of sunlight which is a rich source of Vitamin D. The objective of this study was to determine the effect of vitamin D supplementation in reducing number of acute exacerbation in COPD patients. This randomized control trial was conducted at East Medical Ward Mayo Hospital Lahore from January to December 2015 as exacerbations of COPD are season dependent. Diagnosis was confirmed by performing Pulmonary Function Tests (PFTs). Basic demographical information was obtained and baseline PFTs of the patient was done. Only Group A patients was treated with oral vitamin D intake of 2000 IU daily for 6 months. Vitamin D level was measured at 0, 2, 4, and 6 months and exacerbation of COPD, FEV1 and FVC was measured weekly. Both the groups were given standard treatment for exacerbation of COPD. Spirometry was repeated at each visit. Blood samples were collected every 2 months for vitamin D. Supplementation was stopped if vitamin D level exceeded 100ng/ml. The mean age of the patients was 46.28±8.83 years, the male to female ratio was 1.8:1. The mean 25(OH) level at baseline was 24.08±2.58 and at 6th month was 29.60±8.74. The mean FVC at baseline was 77.83±5.49 and at 6th month was 91.34±5.52. The exacerbation at baseline was present in all 120(100%) patients and at 6th month was reduced to 4(3.3%). Vitamin D supplementation has significant effect in reducing number of acute exacerbation in COPD patients when it is given for prolonged period.

    Conclusion: Quality of life is impaired in patients with COPD and it deteriorates considerably with increasing severity of disease. Increasing severity of COPD is associated with a significant increase in SGRQ-C score. A higher smoking index affects the COPD subjects’ QOL especially with patients’ symptoms and impact of disease. Psychological assessment and psychiatric consultation are important for improving COPD symptoms, QOL and for early detection and treatment of superimposed psychiatric symptoms that could worsen COPD condition and seriously affect QOL.

    COPD is a global concern. Currently, several sets of guidelines, statements and strategies to managing COPD exist around the world. The Czech Pneumological and Phthisiological Society (CPPS) has commissioned an Expert group to draft recommended guidelines for the management of stable COPD. Subsequent revisions were further discussed at the National Consensus Conference (NCC). Reviewers' comments contributed to the establishment of the document's final version. The hallmark of the novel approach to COPD is the integrated evaluation of the patient's lung functions, symptoms, exacerbations and identifications of clinical phenotype(s). The CPPS defines 6 clinically relevant phenotypes: frequent exacerbator, COPD-asthma overlap, COPD-bronchiectasis overlap, emphysematic phenotype, bronchitic phenotype and pulmonary cachexia phenotype. Treatment recommendations can be divided into four steps. 1(st) step = Risk exposure elimination: reduction of smoking and environmental tobacco smoke (ETS), decrease of home and occupational exposure risks. 2(nd) step = Standard treatment: inhaled bronchodilators, regular physical activity, pulmonary rehabilitation, education, inhalation training, comorbidity treatment, vaccination. 3(rd) step = Phenotype-specific therapy: PDE4i, ICS+LABA, LVRS, BVR, AAT augmentation, physiotherapy, mucolytic, ABT. 4(th) step = Care for respiratory insufficiency and terminal COPD: LTOT, lung transplantation, high intensity-NIV and palliative care. Optimal treatment of COPD patients requires an individualised, multidisciplinary approach to the patient's symptoms, clinical phenotypes, needs and wishes. The new Czech COPD guideline reflects and covers these requirements.

    Chronic Obstructive Pulmonary Disease (COPD) is a common disease. The main risk factor is smoking although 15% of the COPD cases are expected to be preventable if the occupational exposures from vapour, gas, dust, and fume were eliminated; the population attributable fraction (PAF). The thesis...... addresses the association between occupational exposure and COPD in a population-based cohort of Danes aged 45-84-years. 4717 participants were included at baseline and 2624 at the four year follow-up. COPD was defined by spirometry and the occupational exposure was based on specialist defined jobs...... and questionnaires. The main occupational exposure was organic dust and 49% reported no lifetime occupational exposure. The results suggest occupational exposures to be associated to COPD also in never smokers and women. We found an exposure-response relation in the cross sectional analyses. The results...

    of COPD and smoked were designated as “possible COPD”. Participants who did not fit the case definition of COPD were asked only about their personal circumstances and smoking habits. Data from these groups were analyzed and compared.Results: Of the 6,600 participants who completed the survey, 404 (6.1% fulfilled the epidemiological case definition of COPD: 137 with diagnosed COPD and 267 possible COPD. The most common comorbidities of COPD were hypertension or cardiovascular diseases (36.1%. Subjects with definite COPD had significantly higher COPD Assessment Test scores than the possible COPD group (14.6±8.32 vs 12.6±6.49, P=0.01 and significantly more comorbid illnesses (P=0.01. The main risk factors contributing to health care utilization in each COPD cohort were higher COPD Assessment Test scores (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.04–1.26, higher modified Medical Research Council Breathlessness Scale scores (OR 1.97, 95% CI 1.11–3.51, and having more than one comorbidity (OR 5.19, 95% CI 1.05–25.61.Conclusion: With estimated prevalence of 6.1% in the general population, COPD in Taiwan has been underdiagnosed. Symptoms and comorbidities were independent risk factors for health care utilization in subjects with definite or possible COPD. There is an urgent need to raise awareness of the importance of early evaluation and prompt treatment for subjects with chronic airway symptoms.

Therefore, early recognition and institution of treatment of this comorbidity significantly improve patient’s quality of life. Recently, a questionnaire called the COPD assessment test (CAT has been incorporated into the Global Initiative for Chronic Obstructive Lung Disease (GOLD guidelines for the management of COPD, and a higher score is associated with increased COPD symptoms.2 Considering the regular use of CAT, it was evaluated whether this tool can also be used to identify anxiety. The CAT score was correlated with the Hospital Anxiety and Depression Scale (HADS to determine the level at which CAT may predict anxiety.

    In COPD, body composition studies have focused primarily on low BMI. We examined obesity (BMI ≥ 30 kg/m(2)) as a risk factor for poor function and longitudinal functional decline. Data from a longitudinal cohort of adults with COPD (n = 1096) and an age- and sex-matched comparison group collected in two in-person visits ∼49 months apart were analyzed. Two measures of functioning were examined: six-minute walk distance (6MWD) and Short Physical Performance Battery (SPPB). Multivariate regression analyses examined relationships of obesity with functioning. Secondary analyses stratified by GOLD classification (GOLD-0/1, GOLD-2, GOLD-3/4). Obesity (53% of COPD cohort) was associated cross-sectionally with 6MWD and SPPB in COPD, and only with 6MWD in the comparison group. Obesity predicted significant functional decline in 6MWD for individuals with COPD (odds ratio (OR) for decline [95% CI] 1.8 [1.1, 2.9]), but not the comparison group. Secondary analyses revealed that the risk of decline was significant only in those with more severe COPD (GOLD 3/4, OR = 2.3 [1.0, 5.4]). Obesity was highly prevalent and was associated with poor function concurrently and with subsequent decline in 6MWD in COPD. Obesity in COPD should be considered a risk not only for more co-morbidities and greater health care use, but also for functional decline.

    To assess evidence for the effectiveness of aerobic exercise training (AET) on the autonomic function (AF) outcomes in patients with chronic obstructive pulmonary disease (COPD). Online databases of PubMed, CINAHL and Web of Science were systematically searched for all years till 26th of January, 2017. Clinical studies assessing any measure of AF following exercise training in patients with COPD were included. Data were extracted from studies with high methodological quality for evidence synthesis. Rating of evidence quality was determined using the GRADE guidelines. The Majority of the included studies utilized continuous exercise training mode with a vigorous level of intensity. Each exercise training session lasted between 30 to 40minutes, and the frequency of intervention was ≥3 times/week. Evidence synthesis of studies with high methodological quality revealed that a high quality evidence level supported a significant increase for time-domain heart rate variability (HRV) analyses and the heart rate recovery (HRR) following AET. The review also found that frequency domain HRV analyses were not significantly affected by AET. The evidence to support the effect of exercise training on baroreceptor sensitivity (BRS) in patients with COPD is very low. Aerobic exercise training demonstrated beneficial but limited effects on the AF in COPD. Presently, it is not clear whether these effects are sustained in the long term. Only a limited number of RCTs were available indicating a significant gap in the literature. Copyright © 2017 Chartered Society of Physiotherapy. Published by Elsevier Ltd. All rights reserved.

The Functional Performance Inventory (FPI was developed based on an analytical framework of functional status and qualitative interviews with COPD patients describing these difficulties. The 65-item FPI was reduced to a 32-item short form (SF through a systematic process of qualitative and quantitative item reduction and formatted for greater clarity and ease of use. This study examined the content validity of the reduced, reformatted form of the instrument, the FPI-SF.Patients and methods: Qualitative cognitive interviews were conducted with COPD patients recruited from three geographically diverse pulmonary clinics in the United States. Interviews were designed to assess respondent interpretation of the instrument, evaluate clarity and ease of completion, and identify any new activities participants found important and difficult to perform that were not represented by the existing items.Results: Twenty subjects comprised the sample; 12 (60% were male, 14 (70% were Caucasian, the mean age was 63.0 ± 11.3 years, 12 (60% were retired, the mean forced expiratory volume in 1 second (FEV1 was 1.5 ± 0.5 L, and the mean percent predicted FEV1 was 48.4% ± 13.1%. Participants understood the FPI-SF as intended, including instructions, items, and response options. Two minor formatting changes were suggested to improve clarity of presentation. Participants found the content of the FPI-SF to be comprehensive, with items covering activities they felt were important and often difficult to perform.Conclusion: These results, together with

    Full Text Available Abstract Background The association between bronchial obstruction severity and mortality in Chronic Obstructive Pulmonary Disease (COPD is well established, but it is unknown whether disease-specific health status measures and multidimensional assessment (MDA have comparable prognostic value. Methods We analyzed data coming from the Salute Respiratoria nell'Anziano (Respiratory Health in the Elderly – SaRA study, enrolling elderly people attending outpatient clinics for respiratory and non-respiratory problems. From this population we selected 449 patients with bronchial obstruction (77.3% men, mean age 73.1. We classified patients' health status using tertiles of the Saint George Respiratory Questionnaire (SGRQ and a MDA including functional (the 6' walking test, WT, cognitive (Mini-Mental State Examination, MMSE and affective status (Geriatric Depression Scale, GDS. The agreement of the classification methods was calculated using the kappa statistic, and survival associated with group membership was evaluated using survival analysis. Results Pulmonary function, expressed by the FEV1, worsened with increasing SGRQ or MDA scores. Cognitive function was not associated with the SGRQ, while physical performance and mood status were impaired only in the highest tertile of SGRQ. A poor agreement was found between the two classification systems tested (k = 0.194. Compared to people in the first tertile of SGRQ score, those in the second tertile had a sex-adjusted HR of 1.22 (0.75 – 1.98 and those in the third tertile of 2.90 (1.92 – 4.40. The corresponding figures of the MDA were 1.49 (95% CI 1.02 – 2.18 and 2.01 (95% CI: 1.31 – 3.08. After adjustment for severity of obstruction, only a SGRQ in the upper tertile was associated with mortality (HR: 1.86; 95% CI: 1.14 – 3.02. Conclusion In elderly outpatients with mild-moderate COPD, a disease-specific health status index seems to be a better predictor of death compared to a MDA.

    Objective: To evaluate the prevalence of sarcopenia in COPD patients, as well as to determine whether sarcopenia correlates with the severity and prognosis of COPD. Methods: A cross-sectional study with COPD patients followed at the pulmonary outpatient clinic of our institution. The patients underwent dual-energy X-ray absorptiometry. The diagnosis of sarcopenia was made on the basis of the skeletal muscle index, defined as appendicular lean mass/height2 only for low-weight subjects and adjusted for fat mass in normal/overweight subjects. Disease severity (COPD stage) was evaluated with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The degree of obstruction and prognosis were determined by the Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE) index. Results: We recruited 91 patients (50 females), with a mean age of 67.4 ± 8.7 years and a mean BMI of 25.8 ± 6.1 kg/m2. Sarcopenia was observed in 36 (39.6%) of the patients, with no differences related to gender, age, or smoking status. Sarcopenia was not associated with the GOLD stage or with FEV1 (used as an indicator of the degree of obstruction). The BMI, percentage of body fat, and total lean mass were lower in the patients with sarcopenia than in those without (p < 0.001). Sarcopenia was more prevalent among the patients in BODE quartile 3 or 4 than among those in BODE quartile 1 or 2 (p = 0.009). The multivariate analysis showed that the BODE quartile was significantly associated with sarcopenia, regardless of age, gender, smoking status, and GOLD stage. Conclusions: In COPD patients, sarcopenia appears to be associated with unfavorable changes in body composition and with a poor prognosis. PMID:26578132

    People with chronic obstructive pulmonary disease (COPD) have poor quality of life, reduced survival, and accelerated decline in lung function, especially associated with acute exacerbations, leading to high healthcare costs. Long-acting bronchodilators are the mainstay of treatment for symptomatic improvement, and umeclidinium is one of the new long-acting muscarinic antagonists approved for treatment of patients with stable COPD. To assess the efficacy and safety of umeclidinium bromide versus placebo for people with stable COPD. We searched the Cochrane Airways Group Specialised Register (CAGR), ClinicalTrials.gov, the World Health Organization (WHO) trials portal, and the GlaxoSmithKline (GSK) Clinical Study Register, using prespecified terms, as well as the reference lists of all identified studies. Searches are current to April 2017. We included randomised controlled trials (RCTs) of parallel design comparing umeclidinium bromide versus placebo in people with COPD, for at least 12 weeks. We used standard Cochrane methodological procedures. If we noted significant heterogeneity in the meta-analyses, we subgrouped studies by umeclidinium dose. We included four studies of 12 to 52 weeks' duration, involving 3798 participants with COPD. Mean age of participants ranged from 60.1 to 64.6 years; most were males with baseline mean smoking pack-years of 39.2 to 52.3. They had moderate to severe COPD and baseline mean post-bronchodilator forced expiratory volume in one second (FEV 1 ) ranging from 44.5% to 55.1% of predicted normal. As all studies were systematically conducted according to prespecified protocols, we assessed risk of selection, performance, detection, attrition, and reporting biases as low.Compared with those given placebo, participants in the umeclidinium group had a lesser likelihood of developing moderate exacerbations requiring a short course of steroids, antibiotics, or both (odds ratio (OR) 0.61, 95% confidence interval (CI) 0.46 to 0.80; four

    Full Text Available Previous family studies suggested that genetic variation contributes to COPD susceptibility. The only gene proven to influence COPD susceptibility is SERPINA1, encoding α1-antitrypsin. Most studies on COPD candidate genes except SERPINA1, have not been consistently replicated. However, longitudinal studies of decline in lung function, meta-analyses of candidate gene studies, and family-based linkage analyses suggested that variants in EPHX1, GST, MMP12, TGFB1, and SERPINE2 were associated with susceptibility to COPD. A genome-wide association (GWA study has recently demonstrated that CHRNA3/5 in 15q25 was associated with COPD compared with control smokers. It was of interest that the CHRNA3/5 locus was associated with nicotine dependence and lung cancer as well. The associations of HHIP on 4q31 and FAM13A on 4q22 with COPD were also suggested in GWA studies. Another GWA study has shown that BICD1 in 12p11 was associated with the presence or absence of emphysema. Although every genetic study on COPD has some limitations including heterogeneity in smoking behaviors and comorbidities, it has contributed to the progress in elucidating the pathogenesis of COPD. Future studies will make us understand the mechanisms underlying the polygenic disease, leading to the development of a specific treatment for each phenotype.

    Chronic obstructive pulmonary disease (COPD) has a high prevalence rate in Germany and a further increase is expected within the next years. Although risk factors on an individual level are widely understood, only little is known about the spatial heterogeneity and population-based risk factors of COPD. Background knowledge about broader, population-based processes could help to plan the future provision of healthcare and prevention strategies more aligned to the expected demand. The aim of this study is to analyze how the prevalence of COPD varies across northeastern Germany on the smallest spatial-scale possible and to identify the location-specific population-based risk factors using health insurance claims of the AOK Nordost. To visualize the spatial distribution of COPD prevalence at the level of municipalities and urban districts, we used the conditional autoregressive Besag-York-Mollié (BYM) model. Geographically weighted regression modelling (GWR) was applied to analyze the location-specific ecological risk factors for COPD. The sex- and age-adjusted prevalence of COPD was 6.5% in 2012 and varied widely across northeastern Germany. Population-based risk factors consist of the proportions of insurants aged 65 and older, insurants with migration background, household size and area deprivation. The results of the GWR model revealed that the population at risk for COPD varies considerably across northeastern Germany. Area deprivation has a direct and an indirect influence on the prevalence of COPD. Persons ageing in socially disadvantaged areas have a higher chance of developing COPD, even when they are not necessarily directly affected by deprivation on an individual level. This underlines the importance of considering the impact of area deprivation on health for planning of healthcare. Additionally, our results reveal that in some parts of the study area, insurants with migration background and persons living in multi-persons households are at elevated risk

    The COPD-LUCSS-DLCO score had been validated as a predictive tool capable of identifying patients with chronic obstructive pulmonary disease (COPD) and a high mortality risk associated with lung cancer (LC); however, studies have not been conducted yet on its use in standard clinical practice. The aim of this study was to estimate the COPD-LUCSS-DLCO scores for patients with COPD treated in Pulmonology consultations and to determine the incidence of LC in each of the subgroups. A retrospective observational study was conducted with a cohort of 159 patients with COPD in Pulmonology outpatient follow-up consultations. We calculated the COPD-LUCSS-DLCO score (0-8) for each patient, with low risk considered at 0-3 points and high risk at ≥3.5 points. We calculated the incidence rate of LC in each of the subgroups. Sixty-two percent of the patients had a high-risk score. We estimated an overall LC rate of 30 per 1000 patients with COPD-year (95% CI: 16-53), 44 per 1000 patients with COPD-year (95% CI: 18-76) among those categorised as high risk and 17 per 1000 patients with COPD-year among those categorised as low risk (95% CI: 4-50). The use of the COPD-LUCSS-DLCO score in standard clinical practice could help detect patients with a greater risk of developing LC, which could help to better manage cases in an LC screening programme.

The objective of this retrospective observational study was to study the long-term outcome of exercise capacity and quality of life during management of patients with COPD treated by home-based PR.Methods: Home-based PR was administered to 211 patients with COPD (mean age, 62.3±11.1 years; mean forced expiratory volume in 1 second, 41.5%±17.7%. Home-based PR was chosen because of the distance of the patient’s home from the PR center and the patient’s preference. Each patient was individually managed by a team member once a week for 8 weeks with unsupervised continuation of physical exercises on the other days of the week according to an individual action plan. Exercise conditioning, therapeutic patient education, and self-management were included in the PR program. The home assessment comprised evaluation of the patient’s exercise capacity by a 6-minute stepper test, Timed Up and Go test, ten times sit-to-stand test, Hospital Anxiety and Depression score, and quality of life (Visual Simplified Respiratory Questionnaire, VQ11, Maugeri Respiratory Failure 28.Results: No incidents or accidents were observed during the course of home-based PR.

    Full Text Available Chronic obstructive pulmonary disease (COPD is responsible for early mortality, high death rates and significant cost to health systems. The projection for 2020 indicates that COPD will be the third leading cause of death worldwide (from sixth in 1990 and fifth leading cause of years lost through early mortality or handicap (disability-adjusted life years (12th in 1990. Active smoking remains the main risk factor, but other factors are becoming better known, such as occupational factors, infections and the role of air pollution. Prevalence of COPD varies according to country, age and sex. This disease is also associated with significant comorbidities. COPD is a disorder that includes various phenotypes, the continuum of which remains under debate. The major challenge in the coming years will be to prevent onset of smoking along with early detection of the disease in the general population.

    To evaluate the clinical value of the multi-detector row computed tomography (MDCT) in the quantitative assessment of lung volumes and to assess the relationship between the MDCT results and disease severity as determined by a pulmonary function test (PFT) in Chronic Obstructive Pulmonary Disease (COPD) patients. We performed a PFT and MDCT on 39 COPD patients. Using the GOLD classifications, we divided the patients into three groups according to disease severity; stage I (mild, n = 10), stage II (moderate, n = 15), and stage III (severe, n = 14). Using the pulmo-CT software program, we measured the proportion of lung volumes with attenuation values below -910 and -950 HU. The mean FEV1 (% of predicted) and FEV1/FVC was 82.2 ± 2% and 66.2 ± 3% in stage I, 53.5 ± 11% and 52 ± 6% in stage II, and 32.3 ± 7% and 44.2% ± 13% in stage III, respectively. Differences in lung volume percentage at each of the thresholds (-910 and -950 HU) among the 3 stages were statistically significant (ρ < 0.01, ρ < 0.01) and correlated well with the FEV1 and FEV1/FVC (r = -0.803, r -0.766, r = -0.817, and r = -0.795, respectively). The volumetric measurement obtained by MDCT provides an accurate means of quantifying pulmonary emphysema

    Three classes of inhaler medications are used to manage chronic obstructive pulmonary disease (COPD): long-acting beta-agonists (LABA), long-acting muscarinic antagonists (LAMA), and inhaled corticosteroids (ICS). When two classes of medications are required, LAMA plus LABA (LAMA+LABA) and LABA plus ICS (LABA+ICS) are often selected because these combinations can be administered via a single medication device. The previous Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidance recommended LABA+ICS as the first-line treatment for managing stable COPD in high-risk people of categories C and D. However, the updated GOLD 2017 guidance recommends LAMA+LABA over LABA+ICS. To compare the benefits and harms of LAMA+LABA versus LABA+ICS for treatment of people with stable COPD. We performed an electronic search of the Cochrane Airways Group Specialised Register (2 February 2016), ClinicalTrials.gov (4 June 2016), and the World Health Organization Clinical Trials Search Portal (4 June 2016), followed by a handsearch (5 June 2016). Two review authors screened and scrutinised the selected articles. We included individual randomised controlled trials, parallel-group trials, and cross-over trials comparing LAMA+LABA and LABA+ICS for stable COPD. The minimum accepted trial duration was one month and trials should have been conducted in an outpatient setting. Two review authors independently extracted data and evaluated risk of bias. We resolved any discrepancies through discussion. We analysed dichotomous data as odds ratios (OR), and continuous data as mean differences (MD), with 95% confidence interval (CI) using Review Manager 5. Exacerbations were measured by counting the number of people experiencing one or more exacerbation. We included 11 studies comprising 9839 participants in our quantitative analysis. Most studies included people with moderate to severe COPD, without recent exacerbations. One pharmaceutical sponsored trial that included only people with

    The magnitude of undiagnosed COPD in our population with cardiovascular risk factors (CVRF) is unknown. The objective of this study was to estimate the prevalence of undiagnosed COPD and its specific characteristics in a population with CVRF. Study the prevalence of COPD in patients with CVRF. Spirometry was performed between 01/01/2015 and 12/31/2016 and the percentage of patients with COPD, who had not previously been diagnosed, was determined. Each patient's variables of interest were recorded; the records of patients who had spirometry showing COPD were checked to confirm whether a diagnosis had been recorded or not. The association of undiagnosed COPD with different independent variables was determined with adjusted odds ratio (aOR) by non conditional logistic regression models. 2,295 patients with CVRF were studied. The overall prevalence of COPD was 14.5%. An underdiagnosis of 73.3% was observed. Newly diagnosed COPD vs. undiagnosed COPD showed to be higher in women (74.1% vs. 36.0%; P=.081), non-smokers (21.3% vs. 12.4%; P=.577), mild cases (GOLD1) (42.6% vs. 32.4%, P=.008) and cases with lower than average HbA1c (5.5% vs. 5.6%; P=.008) and uric acid (5.1mg/dL vs. 5.6mg/dL; P=.011). The variables associated with undiagnosed COPD were: women (aOR=1.27; 95%CI: 0.74-2.17; P=.383); age (aOR=0.94; 95%CI: 0.87-0.99; P=.018); smokers (smoker/non-smoker) (aOR=0.47; 95%CI: 0.22-1.01; P=.054) and HbA1c (%) (aOR=0.45; 95%CI: 0.23-0.88; P=.019). The under-diagnosis of COPD is very high. The contact patients aged between 50 and 65 years-old who have CVRF with their health system should be reassessed, and they need to ask for a spirometry.

    To estimate the prevalence of undiagnosed chronic obstructive pulmonary disease (COPD) in a population of general practice patients at risk for developing COPD. A further aim was to evaluate the presence of respiratory symptoms as a predictor for the diagnosis of COPD. This study was conducted by eight general practitioners (GP) in six semi-rural general practices. During two consecutive months all patients attending their GP were included if they met the following criteria: current smokers between 40 and 70 yr of age, and a smoking history of at least 15 pack-years. A questionnaire regarding smoking history, respiratory symptoms, exposure to dust or chemical fumes, and history of respiratory diseases was completed for all patients. Subjects without known COPD were invited for spirometric testing. Off the 146 general practice patients included, 17.1% already had an established COPD diagnosis. Screening by spirometry revealed a 46.6% prevalence of COPD. Underdiagnosis of COPD was more frequent in the younger age categories (40-49 Yr; 50-59 Yr). Objective wheezing was the only sign that was significantly more frequent in COPD patients than in non-COPD patients (Pfatigue than newly detected patients. Almost half of a general practice population of current smokers between 40 and 70 years of age, with a smoking history of at least 15 pack-years, was diagnosed with COPD, and roughly two thirds of these were newly detected as a result of the case finding programme.

    Chronic obstructive pulmonary disease (COPD) patients have a high incidence of gastroesophageal reflux disease (GERD) whose pathophysiology seems to be linked to an increased trans-diaphragmatic pressure gradient and not to a defective esophagogastric barrier. Inhaled beta agonist bronchodilators are a common therapy used by patients with COPD. This drug knowingly not only leads to a decrease in the lower esophageal sphincter (LES) resting pressure, favoring GERD, but also may improve ventilatory parameters, therefore preventing GERD. This study aims to evaluate the effect of inhaled beta agonist bronchodilators on the trans-diaphragmatic pressure gradient and the esophagogastric barrier. We studied 21 patients (mean age 67 years, 57 % males) with COPD and GERD. All patients underwent high-resolution manometry and esophageal pH monitoring. Abdominal and thoracic pressure, trans-diaphragmatic pressure gradient (abdominal-thoracic pressure), and the LES retention pressure (LES basal pressure-transdiaphragmatic gradient) were measured before and 5 min after inhaling beta agonist bronchodilators. The administration of inhaled beta agonist bronchodilators leads to the following: (a) a simultaneous increase in abdominal and thoracic pressure not affecting the trans-diaphragmatic pressure gradient and (b) a decrease in the LES resting pressure with a reduction of the LES retention pressure. In conclusion, inhaled beta agonist bronchodilators not only increase the thoracic pressure but also lead to an increased abdominal pressure favoring GERD by affecting the esophagogastric barrier.

    There is no independent standardized self-management approach available for chronic obstructive pulmonary disease (COPD). The aim of this project was to develop and test a novel self-management manual for individuals with COPD. Participants with a confirmed diagnosis of COPD were recruited from primary care. A novel self-management manual was developed with health care professionals and patients. Five focus groups were conducted with individuals with COPD (N = 24) during development to confirm and enhance the content of the prototype manual. The Self-management Programme of Activity, Coping and Education for Chronic Obstructive Pulmonary Disease (SPACE for COPD) manual was developed as the focus of a comprehensive self-management approach facilitated by health care professionals. Preference for delivery was initial face-to-face consultation with telephone follow-up. The SPACE for COPD manual was piloted with 37 participants in primary care. Outcome measures included the Self-Report Chronic Respiratory Questionnaire, Incremental Shuttle Walk Test, and Endurance Shuttle Walking Test (ESWT); measurements were taken at baseline and 6 weeks. The pilot study observed statistically significant improvements for the dyspnea domain of the Self-Report Chronic Respiratory Questionnaire and ESWT. Dyspnea showed a mean change of 0.67 (95% confidence interval 0.23-1.11, P = 0.005). ESWT score increased by 302.25 seconds (95% confidence interval 161.47-443.03, P COPD. The program, incorporating the SPACE for COPD manual, appears to provoke important changes in exercise capacity and breathlessness for individuals with COPD managed in primary care.

    COPD is a heterogeneous disease defined by expiratory airflow limitation. Airflow limitation is caused by a variable combination of emphysematous destruction of lung parenchyma and small airway obstruction. Only advanced emphysema can be diagnosed by chest X-ray. Less severe emphysema and changes in small airways are commonly diagnosed by computed tomography. Typical visual appearance of pathologic changes in lung parenchyma and airways of COPD patients are presented, furthermore methods for quantitative assessment of these changes and the crucial role of imaging for surgical and bronchoscopic treatment in COPD are discussed.

    In the performed study, the infections caused by multi-resistant Acinetobacter baumannii, were observed in COPD, which should be taken into consideration in choosing empirical antibiotic therapy. Simultaneously, the local resistance patterns of multi-drug-resistant (MDR Gram-negative strains co-infecting COPD should be considered in empirical treatment. Moreover, both additional clinical complication and co-infections contribute to a more severe course of diseases. In this study, the mortality percent exceeded 29%.

    Skeletal muscle dysfunction is a common feature in chronic obstructive pulmonary disease (COPD) which is associated with intrinsic muscular abnormalities. One of the most consistently reported alterations is a shift from fibre type I to II in the vastus lateralis of these patients. Surprisingly, the relationship between this shift and the severity and phenotype of COPD remains unclear. A study was conducted to determine whether vastus lateralis muscle fibre type proportions are associated with COPD disease severity and to provide reference values for the proportions of fibre types in the vastus lateralis in COPD. A systematic review and a meta-analysis were conducted in which muscle fibre type data and markers of disease severity were collected from the literature. The forced expiratory volume in 1 s (FEV(1)), the ratio of FEV(1) to forced vital capacity (FVC) and body mass index were positively associated with the proportion of type I fibres in COPD. A proportion of 51% for vastus lateralis fibre type I and 13% for fibre type IIX were calculated from the combined data as normal values for patients with typical GOLD stage 3-4 COPD aged 60-70 years. Based on these reference values, a proportion of fibre type I 29% were defined as pathologically abnormal. This review sheds new light on the relationship between skeletal muscle abnormalities and important hallmarks of the disease in severe COPD, and identifies absence of data in GOLD stages 1-2. This review also provides reference values on fibre type composition for diagnostic purposes in COPD.

    As the global burden of chronic disease rises, policy makers are showing a strong interest in adopting telehealth technologies for use in long term condition management, including COPD. However, there remain barriers to its implementation and sustained use. To date, there has been limited qualitative investigation into how users (both patients/carers and staff) perceive and experience the technology. We aimed to systematically review and synthesise the findings from qualitative studies that investigated user perspectives and experiences of telehealth in COPD management, in order to identify factors which may impact on uptake. Systematic review and meta-synthesis of published qualitative studies of user (patients, their carers and clinicians) experience of telehealth technologies for the management of Chronic Obstructive Pulmonary Disease. ASSIA, CINAHL, Embase, Medline, PsychInfo and Web of Knowledge databases were searched up to October 2014. Reference lists of included studies and reference lists of key papers were also searched. Quality appraisal was guided by an adapted version of the CASP qualitative appraisal tool. 705 references (after duplicates removed) were identified and 10 papers, relating to 7 studies were included in the review.

    This paper describes a novel method that can evaluate chronic obstructive pulmonary disease (COPD) severity by combining measurements of pulmonary function tests and measurements obtained from CT image analysis. There is no cure for COPD. However, with regular medical care and consistent patient compliance with treatments and lifestyle changes, the symptoms of COPD can be minimized and progression of the disease can be slowed. Therefore, many diagnosis methods based on CT image analysis have been proposed for quantifying COPD. Most of diagnosis methods for COPD extract the lesions as low-attenuation areas (LAA) by thresholding and evaluate the COPD severity by calculating the LAA in the lung (LAA%). However, COPD is usually the result of a combination of two conditions, emphysema and chronic obstructive bronchitis. Therefore, the previous methods based on only LAA% do not work well. The proposed method utilizes both of information including the measurements of pulmonary function tests and the results of the chest CT image analysis to evaluate the COPD severity. In this paper, we utilize a multi-class AdaBoost to combine both of information and classify the COPD severity into five stages automatically. The experimental results revealed that the accuracy rate of the proposed method was 88.9% (resubstitution scheme) and 64.4% (leave-one-out scheme).

    Full Text Available BACKGROUND Chronic Obstructive Pulmonary Disease (COPD is a disease state characterised by the presence of airflow obstruction due to chronic bronchitis or emphysema, which is progressive and partially reversible. Right ventricular failure (cor pulmonale is a well-known complication of COPD. But, it also involves left ventricle leading to systolic as well as diastolic dysfunction, which maybe present with associated RV failure and also as a separate entity. Diastolic dysfunction is due to defective filling of the left ventricle because of the hyperinflated lung. On the other hand, systolic dysfunction maybe secondary to RV failure due to the effects of hypoxia in the cardiac muscle fibres as a part of the systemic hypoxaemia or it may be due to the effects of the circulatory inflammatory mediators leading to atherosclerosis and ischaemia of cardiac muscles. MATERIALS AND METHODS It was a prospective study of 100 patients of COPD classified according to GOLD criteria with or without cor pulmonale admitted to our hospital in the period of January 2014 to October 2015 meeting our inclusion and exclusion criteria. Investigations like chest x-ray, spirometry, 2D-echocardiography and electrocardiography were done and data was collected. Data were pooled and interpreted using standard statistical methods. RESULTS Prevalence of COPD was common after middle age, the peak being around 5th and 6 th decade of life without much gender inequality. Cor pulmonale was found in 65% patients of COPD, of which more number were in the severe COPD. LV systolic dysfunction was found in 44% of all COPD patients and LV diastolic dysfunction was found in 59% of cases. LV diastolic dysfunction was found in 64% and LV systolic dysfunction was found in 49% of patients of COPD with cor pulmonale. LV systolic dysfunction was found in 62% of COPD patients who showed a resting hypoxaemia (SpO2 <90%. CONCLUSION In our study of 100 COPD patients, we found LV diastolic dysfunction

    An abstract, including parts of the results, has been presented at an oral session at the European Respiratory Society International Conference, London, UK, September 2016. Cardiovascular comorbidity contributes to increased mortality among subjects with COPD. However, the prognostic value of ECG abnormalities in COPD has rarely been studied in population-based surveys. To assess the impact of ischemic ECG abnormalities (I-ECG) on mortality among individuals with COPD, compared to subjects with normal lung function (NLF), in a population-based study. During 2002-2004, all subjects with FEV 1 /VC ECG in COPD (n=635) and referents [n=991, whereof 786 had NLF]. All ECGs were Minnesota-coded. Mortality data were collected until December 31, 2010. I-ECG was equally common in COPD and NLF. The 5-year cumulative mortality was higher among subjects with I-ECG in both groups (29.6% vs 10.6%, P ECG had increased risk for death assessed as the mortality risk ratio [95% confidence interval (CI)] when compared with NLF without I-ECG, 2.36 (1.45-3.85) and 1.65 (0.94-2.90) when adjusted for common confounders. When analyzed separately among the COPD cohort, the increased risk for death associated with I-ECG persisted after adjustment for FEV 1 % predicted, 1.89 (1.20-2.99). A majority of those with I-ECG had no previously reported heart disease (74.2% in NLF and 67.3% in COPD) and the pattern was similar among them. I-ECG was associated with an increased risk for death in COPD, independent of common confounders and disease severity. I-ECG was of prognostic value also among those without previously known heart disease.

    The burden of advanced COPD is high globally; however, little is known about how often end of life strategies are used by this population. To describe trends in the use of end of life care strategies by people with advanced COPD in Ontario, Canada. A population-based repeated cross-sectional study examining end of life care strategies in individuals with advanced COPD was conducted. Annual proportions of individuals who received formal palliative care, long-term oxygen therapy or opioids from 2004 to 2014 were determined. Results were age- and sex- standardized as well as stratified by age, sex, socioeconomic status, urban/rural residence and immigrant status. Measurement/Main Results: There were 151,912 persons with advanced COPD in Ontario between 2004 and 2014. Use of formal palliative care services increased 1% per year from 5.3% in 2004 to 14.3% in 2014 (p value for trend COPD using end of life strategies, although increasing, remains low. Efforts should focus on increasing access to such strategies as well as educating patients and providers of their benefits.

    Objective: To explore the clinical significance of the changes of serum insulinlike growth factor II (IGF-II) levels in patients with chronic obstruive pulmonary diseases (COPD). Methods: The serum IGF-II levels was determined with radioimmunoassay in 60 patients with COPD and 30 controls. Results: The serum IGF-II levels in patients with COPD were significantly higher than those in controls (0.65 ± 0.22μg/L vs 0.51±0.18μg/L, P<0.01). There were no significant differences among the levels in patients of different stages (stages I, II, III). Levels of IGF-II were significantly higher in patients succumbed to the dis- ease than those in patients recoverd (P<0.05). Conclusion: Serum IGF-II levels were significantly increased in patients with COPD, especially in those succumbed. (authors)

    Chronic obstructive pulmonary disease (COPD) is often associated with chronic pain, but pain in COPD remains poorly understood, particularly in comparison to pain in other groups. We compared the pain reported by people with COPD with that reported by arthritis, heart disease, diabetes, and those not reporting any disease, while adjusting for the effects of selected sociodemographic and lifestyle factors, comorbidities, anxiety, and depression. Using cross-sectional data from a population-based health survey in Norway (HUNT3; n = 50,807), we included participants with COPD (n = 1199), participants without COPD, but with arthritis (n = 8582), heart disease (n = 4109), or diabetes (n = 1254), and participants without any disease (n = 18,811). Logistic and linear regression analyses were performed to estimate the probability of reporting chronic pain and the level of pain intensity in the different groups adjusting for other relevant factors. Approximately half (51.8%) of people with COPD reported chronic pain, which was a significantly higher rate than in the diabetes and non-disease groups, and similar to the heart disease group. People with arthritis had a chronic pain rate of 75.4%, which was higher than all other groups, including COPD. Analyses of pain intensity yielded similar findings, with the COPD group having higher pain intensity than the diabetes and non-disease groups, similar pain intensity as the heart disease group, and less pain intensity than the arthritis group. The likelihood of chronic pain and the intensity of pain were generally higher among women, people employed in occupations with low educational requirements, smokers, and those with comorbidity. Chronic pain rates and pain intensity increased with age and higher anxiety and depression scores, and were inversely related to physical activity. People with COPD are at increased risk for chronic pain and higher pain intensity, second only to those with arthritis among the

    The use of adequate self-management strategies for people with chronic obstructive pulmonary disease (COPD) reduces healthcare use, improves health-related quality of life (HRQoL) and recovery after acute exacerbations. However, not many people with COPD receive support that promotes the use of such strategies and therefore new methods to facilitate and promote the use of self-management strategies are highly warranted. This pilot trial aims to evaluate the feasibility of the study design and study procedures considering effectiveness of the novel intervention, the COPD-web. METHODS AND ANALYSIS: The overall design is a pragmatic controlled pilot trial with preassessments and postassessments and a parallel process evaluation. Patients with the diagnosis of COPD will be eligible for the study. The intervention group will be recruited when visiting one of the six participating primary care units in Sweden. The control group will be identified from the unit's computerised registers. The intervention, the COPD-web, is an interactive web page with two sections; one directed at people with COPD and one at healthcare professionals. The sections aim to support patients' self-management skills-and to facilitate the provision of support for self-management strategies, respectively. Effectiveness with regard to patients' symptoms, HRQoL, knowledge of and readiness for COPD-related self-management, health literacy, self-efficacy for physical activity and time spent in physical activity and time being sedentary, and further, healthcare professionals' knowledge of and readiness to support COPD-related self-management strategies will be assessed using questionnaires at 3 and 12 months. The process evaluation will include observations and interviews. Ethical approval has been obtained. Findings will be presented at conferences, submitted for publication in peer-reviewed publications and presented to the involved healthcare professionals, patients and to patient organisations

    Patients with chronic obstructive pulmonary disease (COPD) are more likely to take time off work (absenteeism) and report poor performance at work (presenteeism) compared to those without COPD. Little is known about the modifiable factors associated with these work productivity outcomes. To assess the factors associated with work productivity among COPD patients. Cross-sectional analysis of baseline data from a subsample (those in paid employment) of the Birmingham COPD Cohort study. Absenteeism was defined by self-report over the previous 12 months. Presenteeism was assessed using the Stanford Presenteeism Scale. Logistic regression analysis was used to assess the effects of sociodemographic, clinical and occupational characteristics on work productivity. Among 348 included participants, increasing dyspnoea was the only factor associated with both absenteeism and presenteeism (p for trend<0.01). Additionally, increasing history of occupational exposure to vapours, gases, dusts or fumes (VGDF) was independently associated with presenteeism (p for trend<0.01). This is the first study to identify important factors associated with poor work productivity among patients with COPD. Future studies should evaluate interventions aimed at managing breathlessness and reducing occupational exposures to VGDF on work productivity among patients with COPD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available The combination of chronic obstructive pulmonary disease (COPD and obstructive sleep apnea (OSA is associated with substantial morbidity and mortality. We hypothesized that predictors of OSA among patients with COPD may be distinct from OSA in the general population. Therefore, we investigated associations between traditional OSA risk factors (e.g. age, and sleep questionnaires [e.g. Epworth Sleepiness Scale] in 44 patients with advanced COPD. As a second aim we proposed a pilot, simplified screening test for OSA in patients with COPD. In a prospective, observational study of patients enrolled in the UCSD Pulmonary Rehabilitation Program we collected baseline characteristics, cardiovascular events (e.g. atrial fibrillation, and sleep questionnaires [e.g. Pittsburgh Sleep Quality Index (PSQI]. For the pilot questionnaire, a BMI ≥25 kg/m2 and the presence of cardiovascular disease were used to construct the pilot screening test. Male: 59%; OSA 66%. FEV1 (mean ± SD = 41.0±18.2% pred., FEV1/FVC = 41.5±12.7%]. Male gender, older age, and large neck circumference were not associated with OSA. Also, Epworth Sleepiness Scale and the STOP-Bang questionnaire were not associated with OSA in univariate logistic regression. In contrast, BMI ≥25 kg/m2 (OR = 3.94, p = 0.04 and diagnosis of cardiovascular disease (OR = 5.06, p = 0.03 were significantly associated with OSA [area under curve (AUC = 0.74]. The pilot COPD-OSA test (OR = 5.28, p = 0.05 and STOP-Bang questionnaire (OR = 5.13, p = 0.03 were both associated with OSA in Receiver Operating Characteristics (ROC analysis. The COPD-OSA test had the best AUC (0.74, sensitivity (92%, and specificity (83%. A ten-fold cross-validation validated our results. We found that traditional OSA predictors (e.g. gender, Epworth score did not perform well in patients with more advanced COPD. Our pilot test may be an easy to implement instrument to screen for OSA. However, a larger validation study is necessary

In contrast, BMI ≥25 kg/m2 (OR = 3.94, p = 0.04) and diagnosis of cardiovascular disease (OR = 5.06, p = 0.03) were significantly associated with OSA [area under curve (AUC) = 0.74]. The pilot COPD-OSA test (OR = 5.28, p = 0.05) and STOP-Bang questionnaire (OR = 5.13, p = 0.03) were both associated with OSA in Receiver Operating Characteristics (ROC) analysis. The COPD-OSA test had the best AUC (0.74), sensitivity (92%), and specificity (83%). A ten-fold cross-validation validated our results. We found that traditional OSA predictors (e.g. gender, Epworth score) did not perform well in patients with more advanced COPD. Our pilot test may be an easy to implement instrument to screen for OSA. However, a larger validation study is necessary before

    BACKGROUND: The concept of clinical control in COPD has been developed to help in treatment decisions, but it requires validation in prospective studies. METHOD: This international, multicenter, prospective study aimed to validate the concept of control in COPD [control = stability (no...... exacerbations or impairment in CAT scores) + low impact (low level of symptoms)]. Data from the screening visit was used to: investigate the level of control, compare characteristics of patients according to the control status, and perform a sensitivity analysis of the levels of control using either clinical...... criteria or questionnaires (COPD Assessment Test -CAT- or Clinical COPD Questionnaire -CCQ-). RESULTS: A total of 314 patients were analysed, mean age was 68.5 years and mean FEV1 was 52.6% of predicted. According to the prespecified criteria 21% of patients were classified as controlled, all of them...

    Full Text Available Abstract Background Fatigue in COPD impairs functional status; however there are few studies examining mechanistic pathways of this symptom. The aims of this study are to compare fatigue between COPD patients and healthy age-matched subjects, and to identify predictors of fatigue in COPD. Methods Seventy four COPD patients, mean age 69.9 (49-87 yrs, mean (SD % predicted FEV1 46.5 (20.0 % and FEV1/FVC ratio 0.45 (0.13 and 35 healthy subjects, mean age 67.1 (50-84 yrs completed the Multidimensional Fatigue Inventory (MFI 20. Patients' assessment included Depression (HADS, lung function, BMI, muscle strength, incremental shuttle walk test (ISWT, exercise oxygen saturation (SpO2, Borg breathlessness (CR-10 and exertion (RPE. Serum level of Interleukin 6 (IL-6 was recorded. Differences in MFI 20 between groups were examined and predictors of fatigue identified using logistic regression. Results Significant differences (p 2 (R2 = .62; of Physical Fatigue: depression, % predicted FEV1, ISWT and age (R2 = .57; Reduced Activity: % predicted FEV1, BMI and depression (R2 = .36; Reduced Motivation: RPE, depression and end SpO2 (R2 = .37 and Mental Fatigue: depression and end SpO2 (R2 = .38. Conclusion All dimensions of fatigue were higher in COPD than healthy aged subjects. Predictive factors differ according to the dimension of fatigue under investigation. COPD-RF is a multi component symptom requiring further consideration.

    Study of the causes of the reduced levels of physical activity in patients with COPD has been scarce and limited to biological factors. To assess the relationship between novel socio-environmental factors, namely dog walking, grandparenting, neighbourhood deprivation, residential surrounding greenness and residential proximity to green or blue spaces, and amount and intensity of physical activity in COPD patients. This cross-sectional study recruited 410 COPD patients from five Catalan municipalities. Dog walking and grandparenting were assessed by questionnaire. Neighbourhood deprivation was assessed using the census Urban Vulnerability Index, residential surrounding greenness by the satellite-derived Normalized Difference Vegetation Index, and residential proximity to green or blue spaces as living within 300 m of such a space. Physical activity was measured during 1 week by accelerometer to assess time spent on moderate-to-vigorous physical activity (MVPA) and vector magnitude units (VMU) per minute. Patients were 85% male, had a mean (SD) age of 69 (9) years, and post-bronchodilator FEV 1 of 56 (17) %pred. After adjusting for age, sex, socio-economic status, dyspnoea, exercise capacity and anxiety in a linear regression model, both dog walking and grandparenting were significantly associated with an increase both in time in MVPA (18 min/day (pCOPD patients.

There is little data on the use of an isolated program using vibration platform training on functional capacity in these patients, which is an area that deserves investigation.Aim: To investigate the effect of training on a vibrating platform (whole-body vibration [WBV] on functional performance and quality of life of subjects with COPD.Methods: A randomized controlled crossover pilot study with eleven subjects with COPD (forced expiratory volume in 1 second [FEV1]% predicted =14.63±11.14; forced vital capacity [FVC]% predicted =48.84±15.21; FEV1/FVC =47.39±11.63 underwent a 12-week WBV training program. Participants were randomized into the intervention group (IG undergoing three sessions per week for a total of 12 weeks and control group (CG without intervention. We evaluated the 6-minute walk test (6MWT, distance walked (DW, duration of the walk (TW, and index of perceived exertion (IPE, quality of life using St George’s Respiratory Questionnaire (SGRQ and developed a 12-week program of training on a vibrating platform.Results: The mean age was 62.91±8.82 years old (72.7% male. The DW increased at the end of training with a difference between groups of 75 m; all domains of the SGRQ improved at the end of training. The effect size Cohen’s d ranged from small to large for all the measured results.Conclusion: These preliminary results suggest that WBV may potentially be a safe and feasible way to improve functional capacity in the 6MWT of patients with COPD undergoing a training program on the vibrating platform as well as in all domains of the SGRQ quality of life

    Health-related quality of life (HRQOL) is impaired in chronic obstructive pulmonary disease (COPD) patients, but determining factors for HRQOL are still not unequivocal. This study measures HRQOL among patients with COPD and aims to determine factors associated with HRQOL. Data for cross-sectional analyses were obtained from the baseline of a cohort study. The study population includes adult COPD patients (disease duration ≥3 months), recruited from primary and secondary care settings in Germany, without acute psychiatric/neurologic disease (exception: affective/ anxiety disorders). HRQOL was assessed using the Short-Form 12 (SF-12) Health Survey Questionnaire, comprising a physical and mental component. Independent variables encompass socio-demographic, disease-specific, treatment-related and psychological factors. Multivariable linear regression analyses were conducted. In total, 206 COPD patients (60.7% male; mean age: 65.3 years) took part in the study. In multivariable analysis, the physical component score showed a significant negative association with the COPD Assessment Test (CAT) (PCOPD.

    Heightened inflammation, including expression of COX-2, is associated with chronic obstructive pulmonary disease (COPD) pathogenesis. The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is reduced in COPD-derived lung fibroblasts. The AhR also suppresses COX-2 in response to cigarette smoke, the main risk factor for COPD, by destabilizing the Cox-2 transcript by mechanisms that may involve the regulation of microRNA (miRNA). Whether reduced AhR expression is responsible for heightened COX-2 in COPD is not known. Here, we investigated the expression of COX-2 as well as the expression of miR-146a, a miRNA known to regulate COX-2 levels, in primary lung fibroblasts derived from non-smokers (Normal) and smokers (At Risk) with and without COPD. To confirm the involvement of the AhR, AhR knock-down via siRNA in Normal lung fibroblasts and MLE-12 cells was employed as were A549-AhRko cells. Basal expression of COX-2 protein was higher in COPD lung fibroblasts compared to Normal or Smoker fibroblasts but there was no difference in Cox-2 mRNA. Knockdown of AhR in lung structural cells increased COX-2 protein by stabilizing the Cox-2 transcript. There was less induction of miR-146a in COPD-derived lung fibroblasts but this was not due to the AhR. Instead, we found that RelB, an NF-κB protein, was required for transcriptional induction of both Cox-2 and miR-146a. Therefore, we conclude that the AhR controls COX-2 protein via mRNA stability by a mechanism independent of miR-146a. Low levels of the AhR may therefore contribute to the heightened inflammation common in COPD patients.

    Objective: To determine the frequency and predictors of chronic bronchitis and COPD among textile workers in Karachi, Pakistan. Study Design: Cross-sectional survey. Place and Duration of Study: Karachi, Pakistan, from October to December 2009. Methodology: Male textile workers from 15 mills of Karachi were inducted. Data was collected using American Thoracic Society respiratory questionnaire (ATS-DLD-78-a) and spirometry. Result: Out of 372 participants, 29 (7.8 percentage) workers had chronic bronchitis (4, 9.1 percentage aged =40 years) and 25 (6.7 percentage) had COPD (12, 27.2 percentage aged ≥40 years). Workers with chronic bronchitis had significantly decreased lung function compared to the healthy workers. Those reporting severe self-perceived dust exposure at work, ≥ 10 pack years of smoking, uneducated, longer duration of work (≥11 years), and ever smokers were more likely to have chronic bronchitis or COPD. In the multivariate analyses, severe self-perceived dust exposure at work (AOR = 7.4; 95 percentage CI: 1.9, 28.0), family history of respiratory illness/symptoms (AOR = 4.8; 95 percentage CI: 1.1, 20.9) and lack of education (AOR = 4.2; 95 percentage CI: 1.1, 16.9) were significant predictors of chronic bronchitis. Duration of work ≥11 years (AOR = 5.5; 95 percentage CI: 1.5, 19.7) and pack years of smoking ≥10 years (AOR = 3.5; 95 percentage CI: 1.1, 11.7) were strong predictors for COPD. Conclusion: There is a high frequency of chronic bronchitis and COPD among textile workers. Multiple important predictors for prevention are identified. (author)

    Highlights: • We investigate physiologic response to standard COPD treatment regimes using OE-MRI. • We assess the potential role of OE-MRI in future drug development studies. • In COPD, OE-MRI parameters showed response to single-dose formoterol. • OE-MRI parameters showed response to 8-week formoterol/budesonide treatment. • OE-MRI measurements are feasible in a small-scale multi-center trial setting. - Abstract: Objectives: Oxygen-enhanced MRI (OE-MRI) biomarkers have potential value in assessment of COPD, but need further evaluation before treatment-induced changes can be interpreted. The objective was to evaluate how OE-MRI parameters of regional ventilation and oxygen uptake respond to standard pharmacological interventions in COPD, and how the response compares to that of gold standard pulmonary function tests. Materials and methods: COPD patients (n = 40), mean FEV{sub 1} 58% predicted normal, received single-dose inhaled formoterol 9 μg, or placebo, followed by 8 weeks treatment bid with a combination of budesonide and formoterol Turbuhaler{sup ®} 320/9 μg or formoterol Turbuhaler{sup ®}. OE-MRI biomarkers were obtained, as well as X-ray computed tomography (CT) biomarkers and pulmonary function tests, in a two-center study. An ANCOVA statistical model was used to assess effect size of intervention measurable in OE-MRI parameters of lung function. Results: OE-MRI data were successfully acquired at both study sites. 8-week treatment with budesonide/formoterol significantly decreased lung wash-out time by 31% (p < 0.01), decreased the change in lung oxygen level upon breathing pure oxygen by 13% (p < 0.05) and increased oxygen extraction from the lung by 58% (p < 0.01). Single-dose formoterol increased both lung wash-out time (+47%, p < 0.05) and lung oxygenation time (+47%, p < 0.05). FEV{sub 1} was improved by single-dose formoterol (+12%, p < 0.001) and 8 weeks of budesonide/formoterol (+ 18%, p < 0.001), consistent with published studies

    To evaluate bacterial colonization and the airway inflammatory response, and its relationship to the frequency of exacerbation in patients with stable chronic obstructive pulmonary disease (COPD). Quantitative bacteriologic cultures, neutrophil elastase, myeloperoxidase (MPO), tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-8 were measured in bronchoalveoler lavage (BAL) in 39 patients with stable COPD [19 with frequent exacerbation (> or = 3/year), and 20 with infrequent] and in 18 healthy controls (10 smokers and 8 non-smokers). BAL revealed the microorganisms with potential pathogenicity above the established threshold (> or = 10(3)cfu/ml) in 68.4% of patients with frequent exacerbation, 55% of infrequent exacerbation, 40% of smokers and 12.5% of non-smokers controls (P=0.05). BAL MPO, IL-8 and TNF-alpha levels were found to be significantly higher in COPD as compared to controls (P=0.001). However, only IL-8 level was significantly higher in COPD patients with frequent exacerbation as compared to infrequent (P=0.001). Airway bacterial load correlated with levels of airway inflammation markers in COPD (P<0.05). The bacterial load and airway inflammation contributes to each other in stable COPD. However, there is a link only between interleukine (IL)-8 and frequent exacerbations. Clearly, the relationship between bacterial colonization, airway inflammation and frequent exacerbations is of major importance in understanding of the COPD pathogenesis.

    Clinical audits have emerged as a potential tool to summarize the clinical performance of healthcare over a specified period of time. However, the effectiveness of audit and feedback has shown inconsistent results and the impact of audit and feedback on clinical performance has not been evaluated for COPD exacerbations. In the present study, we analyzed the results of two consecutive nationwide clinical audits performed in Spain to evaluate both the in-hospital clinical care provided and the feedback strategy. The present study is an analysis of two clinical audits performed in Spain that evaluated the clinical care provided to COPD patients who were admitted to the hospital for a COPD exacerbation. The first audit was performed from November-December 2008. The feedback strategy consisted of personalized reports for each participant center, the presentation and discussion of the results at regional, national and international meetings and the creation of health-care quality standards for COPD. The second audit was part of a European study during January and February 2011. The impact of the feedback strategy was evaluated in term of clinical care provided and in-hospital survival. A total of 94 centers participated in the two audits, recruiting 8,143 admissions (audit 1∶3,493 and audit 2∶4,650). The initially provided clinical care was reasonably acceptable even though there was considerable variability. Several diagnostic and therapeutic procedures improved in the second audit. Although the differences were significant, the degree of improvement was small to moderate. We found no impact on in-hospital mortality. The present study describes COPD hospital care in Spanish hospitals and evaluates the impact of peer-benchmarked, individually written and group-oral feedback strategy on the clinical outcomes for treating COPD exacerbations. It describes small to moderate improvements in the clinical care provided to COPD patients with no impact on in

    Plasma proadrenomedullin (ProADM) is a blood biomarker that may aid in multidimensional risk assessment of patients with chronic obstructive pulmonary disease (COPD). Co-secreted 1:1 with adrenomedullin (ADM), ProADM is a less biologically active, more chemically stable surrogate for this pluripotent regulatory peptide, which due to biological and ex vivo physical characteristics is difficult to reliably directly quantify. Upregulated by hypoxia, inflammatory cytokines, bacterial products, and shear stress and expressed widely in pulmonary cells and ubiquitously throughout the body, ADM exerts or mediates vasodilatory, natriuretic, diuretic, antioxidative, anti-inflammatory, antimicrobial, and metabolic effects. Observational data from four separate studies totaling 1366 patients suggest that as a single factor, ProADM is a significant independent, and accurate, long-term all-cause mortality predictor in COPD. This body of work also suggests that combined with different groups of demographic/clinical variables, ProADM provides significant incremental long-term mortality prediction power relative to the groups of variables alone. Additionally, the literature contains indications that ProADM may be a global cardiopulmonary stress marker, potentially supplying prognostic information when cardiopulmonary exercise testing results such as 6-min walk distance are unavailable due to time or other resource constraints or to a patient's advanced disease. Prospective, randomized, controlled interventional studies are needed to demonstrate whether ProADM use in risk-based guidance of site-of-care, monitoring, and treatment decisions improves clinical, quality-of-life, or pharmacoeconomic outcomes in patients with COPD.

    Among persons with obstructive airway disease, the relative contributions of chronic obstructive pulmonary disease (COPD), asthma, and common comorbid conditions to health care utilization and patient-centered outcomes (PCOs) have not been previously reported. We followed a total of 3,486 persons aged ≥40 years with COPD, asthma, or both at baseline, from the Medical Expenditure Panel Survey (MEPS) cohorts enrolled annually from 2008 through 2012 for 1 year. MEPS is a prospective observational study of US households recording self-reported COPD, asthma, and ten medical conditions: angina, arthritis, cancer, coronary heart disease, cognitive impairment, diabetes, hypertension, lung cancer, myocardial infarction, and stroke/transient ischemic attack. We studied the separate contributions of these conditions to health care utilization (all-cause and respiratory disease hospitalization, any emergency department [ED] visit, and six or more outpatient visits) and PCOs (seven or more days spent in bed due to illness, incident loss of mobility, and incident decline in self-perceived health). COPD made the largest contributions to all-cause and respiratory disease hospitalization and ED visits, while arthritis made the largest contribution to outpatient health care. Arthritis and COPD, respectively, made the greatest contributions to the PCOs. COPD made the largest and second largest contributions to health care utilization and PCOs among US adults with obstructive airway disease. The twelve medical conditions collectively accounted for between 52% and 61% of the health care utilization outcomes and between 53% and 68% of the PCOs. Cognitive impairment, diabetes, hypertension, and stroke also made significant contributions.

Well-characterized symptoms such as exertional dyspnea and fatigue have a negative impact on patients’ quality of life (QoL and restrict physical activity in daily life. The impact of COPD symptoms on QoL is often underestimated; for example, 36% of patients who describe their symptoms as being mild-to-moderate also admit to being too breathless to leave the house. Additionally, early morning and nighttime symptoms are a particular problem. Methods are available to allow clinicians to accurately assess COPD symptoms, including patient questionnaires. Integrated approaches to COPD management, particularly pulmonary rehabilitation, are effective strategies for addressing symptoms, improving exercise capacity and, potentially, also increasing physical activity. Inhaled bronchodilators continue to be the mainstay of drug therapy in COPD, where options can be tailored to meet patients’ needs with careful selection of the inhaled medication and the device used for its delivery. Overall, an integrated approach to disease management should be considered for improving QoL and subsequent patient outcomes in COPD.

    chronic lung disease will help develop a new patient reported experience scale. Healthcare services are aiming to provide effective patient-centered care for those with chronic obstructive pulmonary disease (COPD). Such care strategies require structured, validated patient feedback scales to facilitate accurate communication between patients, carers and healthcare professionals. Susan Walker at Anglia Ruskin University in Chelmsford, UK, and co-workers analyzed qualitative data from interviews with 64 COPD patients in London and Essex regarding their emotions and perceptions of living with COPD, with the aim of creating a patient reported experience measure, or PREM. Initial results identified five themes-including 'journey to diagnosis' and 'everyday life'-and twenty-one affective responses, ranging from negative to positive. The team will take these results forward for further validation.

    Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of chronic morbidity and mortality. Bronchial obstruction and increased pulmonary vascular resistance impairs right atrial functions. In this study, we aimed to investigate the effect of bronchial obstruction on p wave axis in patients with COPD and usefulness of electrocardiography (ECG) in the evaluation of the severity of COPD. Ninety five patients (64 male and 31 female) included to the study. Patients were in sinus rhythm, with normal ejection fraction and heart chamber sizes. Their respiratory function tests and 12 lead electrocardiograms were obtained at same day. Correlations with severity of COPD and ECG findings including p wave axis, p wave duration, QRS axis, QRS duration were studied. The mean age was 58 ± 12 years. Their mean p wave axis was 62 ± 18 degrees. In this study, p wave axis has demonstrated significant positive correlations with stages of COPD and QRS axis but significant negative correlations with FEV1, FEF, BMI and QRS duration. P wave axis increases with increasing stages of COPD. Verticalization of the frontal p wave axis may be an early finding of worsening of COPD before occurrences of other ECG changes of hypertrophy and enlargement of right heart chambers such as p pulmonale. Verticalization of the frontal p wave axis reflecting right atrial electrical activity and right heart strain may be a useful parameter for quick estimation of the severity of COPD in an out-patient cared.

    Full Text Available BACKGROUND The drop in oxygen saturation during sleep is more than during exercise and patients of COPD who spend more time in sleeping. Significant sleep desaturation and the sleep disturbances are greater in overlap syndrome than in OSA alone. The present study is conducted in Gayathri Vidya Parishad Institute of Healthcare and Medical Technology, Visakhapatnam, AP, India, to find the prevalence of obstructive sleep apnoea in the patients with COPD. AIMS The present study was a cross-sectional study prospectively carried out with an aim to evaluate the breathing disorders during sleep in patients with COPD and to correlate these disorders with the stage of the disease. SETTINGS AND DESIGN The study Cohort was constituted by patients of COPD registered into Chest OPD or admitted in Indoor units of Gayathri Vidya Parishad Institute of Healthcare and Medical Technology, Visakhapatnam, AP, India, from July 2014 to May 2016. A total of thirty six consecutive COPD patients who consented to be enrolled into the study were classified into Mild, Moderate and Severe stages based on the Indian Guidelines for the management of COPD. METHODS AND MATERIAL Spirometric evaluation and bronchial reversibility testing was conducted in all the patients. Arterial Blood Gas Analysis was done using ABL3 arterial blood gas analyser (Radiometer, Copenhagen. POLYSOMNOGRAPHY Patients were hooked to Compumedics ProFusion Polysomnographic Machine (Compumedics Private Limited 2001, USA, by standard gold cups/electrodes. Thereafter, the patients were subjected to a full night sleep study (Overnight polysomnography. The electrode and sensor connection system utilises E-series EEG/PSG system in order to record the PSG study. The impedance of electrodes was checked and set to <10. A total of 20 leads were utilised for the study. The various parameters monitored included Electroencephalogram (EEG, Electro-oculogram (EOG, Electrocardiogram (ECG, chin and leg Electromyogram (EMG

    Chronic obstructive pulmonary disease (COPD) exacerbations have a negative impact on the quality of life of patients and the evolution of the disease. We have investigated the prognostic value of several health-related quality of life questionnaires to predict the appearance of a composite event (new ambulatory or emergency exacerbation, hospitalization, or death) over a 1-year follow-up. This was a multicenter, prospective, observational study. Patients completed four questionnaires after recovering from an exacerbation (COPD Assessment Test [CAT], a Clinical COPD Questionnaire [CCQ], COPD Severity Score [COPDSS], and Airways Questionnaire [AQ20]). Patients were followed-up until the appearance of the composite event or for 1 year, whichever came first. A total of 497 patients were included in the study. The majority of them were men (89.7%), with a mean age of 68.7 (SD 9.2) years, and a forced expiratory volume in 1 second of 47.1% (SD 17.5%). A total of 303 (61%) patients experienced a composite event. Patients with an event had worse mean scores of all questionnaires at baseline compared to patients without event: CAT=12.5 vs 11.3 (P=0.028); CCQ=2.2 vs 1.9 (P=0.013); COPDSS=12.3 vs 10.9 (P=0.001); AQ20=8.3 vs 7.5 (P=0.048). In the multivariate analysis, only previous history of exacerbations and CAT score ≥13.5 were significant risk factors for the composite event. A CAT score ≥13.5 increased the predictive value of previous exacerbations with an area under the receiver operating characteristic curve of 0.864 (95% CI: 0.829-0.899; P=0.001). The predictive value of previous exacerbations significantly increased only in one of the four trialled questionnaires, namely in the CAT questionnaire. However, previous history of exacerbations was the strongest predictor of the composite event.

    It is not clear whether vitamin D should be actively supplemented in elderly patients suffering from an acute attack of COPD (AECOPD) and coronary heart disease (CHD). The patients were divided into three groups according to specific criteria: patients with AECOPD (group A), patients with COPD combined with CHD (group B), and patients with CHD (group C). We measured the levels of vitamin D and analyzed the correlation between vitamin D and important electrolytes, including prealbumin, creatinine, hemoglobin, cystatin C, blood fat, blood calcium, and blood magnesium, and the nutrition state of the whole body. The serum B-type natriuretic peptide (BNP) was measured using an ELISA kit. The vitamin D level in group B was the lowest, followed by group A. When compared with group C, they all had statistical significance (Pvitamin D (P>0.05). When elderly patients have coronary artery disease with AECOPD, vitamin D levels were obviously lower and were negatively correlated with the BNP. Low vitamin D levels, as well as poor nutrition, affect cardiopulmonary function and quality of living of elderly patients, especially female patients. Therefore, vitamin D should be supplemented more actively in the female patients suffering from AECOPD and CHD.

    Highlights: • Dynamic X-ray phrenicography is a useful method for the evaluation of the diaphragms. • Its radiation dose is comparable to conventional two projection chest radiography. • Diaphragm motion during tidal breathing is larger in COPD than in normal subjects. • Higher BMI is also associated with increased excursions of the bilateral diaphragm. - Abstract: Objectives: To quantitatively compare diaphragmatic motion during tidal breathing in a standing position between chronic obstructive pulmonary disease (COPD) patients and normal subjects using dynamic chest radiography. Materials and methods: Thirty-nine COPD patients (35 males; age, 71.3 ± 8.4 years) and 47 normal subjects (non-smoker healthy volunteers) (20 males; age, 54.8 ± 9.8 years) underwent sequential chest radiographs during tidal breathing using dynamic chest radiography with a flat panel detector system. We evaluated the excursions and peak motion speeds of the diaphragms. The results were analyzed using an unpaired t-test and a multiple linear regression model. Results: The excursions of the diaphragms in COPD patients were significantly larger than those in normal subjects (right, 14.7 ± 5.5 mm vs. 10.2 ± 3.7 mm, respectively, P < 0.001; left, 17.2 ± 4.9 mm vs. 14.9 ± 4.2 mm, respectively, P = 0.022). Peak motion speeds in inspiratory phase were significantly faster in COPD patients compared to normal subjects (right, 16.3 ± 5.0 mm/s vs. 11.8 ± 4.2 mm/s, respectively, P < 0.001; left, 18.9 ± 4.9 mm/s vs. 16.7 ± 4.0 mm/s, respectively, P = 0.022). The multivariate analysis demonstrated that having COPD and higher body mass index were independently associated with increased excursions of the bilateral diaphragm (all P < 0.05), after adjusting for other clinical variables. Conclusions: Time-resolved quantitative evaluation of the diaphragm using dynamic chest radiography demonstrated that the diaphragmatic motion during tidal breathing in a standing position is larger and

    Japan is an aging society, and the number of elderly patients with asthma and chronic obstructive pulmonary disease (COPD) is consequently increasing, with an estimated incidence of approximately 5 million. In 2014, asthma-COPD overlap syndrome (ACOS) was defined by a joint project of Global Initiative for Asthma (GINA) committee and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) committee. The main aims of this consensus-based document are to assist clinicians, especially those in primary care or nonpulmonary specialties. In this article, we discussed parameters to differentiate asthma and COPD in elderly patients and showed prevalence, clinical features and treatment of ACOS on the basis of the guidelines of GINA and GOLD. Furthermore, we showed also referral for specialized investigations.

    Objective Among elderly patients with chronic obstructive pulmonary disease (COPD), there are some patients who cannot inhale tiotropium via Respimat ® due to poor hand-lung coordination. This study aimed to examine whether or not tiotropium inhalation therapy using Respimat ® with a spacer increased the forced expiratory volume in 1 s (FEV 1 ) in patients with COPD. Methods A randomized, crossover, single-center study was conducted in 18 patients with stable COPD. Tiotropium (5 μg) via Respimat ® with or without a spacer (AeroChamber ® ) was administered for 2 weeks. Following a 2-week washout period using a transdermal tulobuterol patch (2 mg per day), participants were then crossed over to the other inhalation therapy with respect to spacer use. The trough FEV 1 was measured at every visit using a spirometer. A questionnaire regarding inhalation therapy was administered to patients at the final visit. Results The administration of tiotropium via Respimat ® both with and without a spacer significantly increased the trough FEV 1 from baseline during each treatment period, with mean differences of 115.0±169.6 mL and 92.8±128.1 mL, respectively. There was no significant difference in the change in the trough FEV 1 between the 2 procedures (p=0.66). A total of 86% of patients reported that inhalation using a spacer was not difficult, and more than half also rated both the usage and maintenance of the AeroChamber ® as easy. Conclusion Tiotropium inhalation therapy administered via Respimat ® using a spacer exerted a bronchodilatory effect similar to that observed with tiotropium Respimat ® alone.

    Full Text Available Abstract Background Although personal cigarette smoking is the most important cause and modulator of chronic obstructive pulmonary disease (COPD, secondhand smoke (SHS exposure could influence the course of the disease. Despite the importance of this question, the impact of SHS exposure on COPD health outcomes remains unknown. Methods We used data from two waves of a population-based multiwave U.S. cohort study of adults with COPD. 77 non-smoking respondents with a diagnosis of COPD completed direct SHS monitoring based on urine cotinine and a personal badge that measures nicotine. We evaluated the longitudinal impact of SHS exposure on validated measures of COPD severity, physical health status, quality of life (QOL, and dyspnea measured at one year follow-up. Results The highest level of SHS exposure, as measured by urine cotinine, was cross-sectionally associated with poorer COPD severity (mean score increment 4.7 pts; 95% CI 0.6 to 8.9 and dyspnea (1.0 pts; 95% CI 0.4 to 1.7 after controlling for covariates. In longitudinal analysis, the highest level of baseline cotinine was associated with worse COPD severity (4.7 points; 95% CI -0.1 to 9.4; p = 0.054, disease-specific QOL (2.9 pts; -0.16 to 5.9; p = 0.063, and dyspnea (0.9 pts; 95% CI 0.2 to 1.6 pts; p Conclusion Directly measured SHS exposure appears to adversely influence health outcomes in COPD, independent of personal smoking. Because SHS is a modifiable risk factor, clinicians should assess SHS exposure in their patients and counsel its avoidance. In public health terms, the effects of SHS exposure on this vulnerable subpopulation provide a further rationale for laws prohibiting public smoking.

    Exacerbations of chronic obstructive pulmonary disease (COPD) have an inflammatory component in addition to the possible infectious component. The antiinflammatory properties of fenspiride (Pneumorel(R) 80 mg) should be evaluated in this frequent clinical situation. Assess the supplementary therapeutic benefit provided by fenspiride administered in combination with antibiotics in COPD patients presenting an episode of bronchial infection. A preliminary randomized placebo-controlled double-blind study was conduced in 7 centers. Patients under 80 years of age of both sexes were included. All patients had COPD and presented a bronchial infection defined as the presence of at least 2 of the 3 criteria defined by Anthonisen. Patients were randomly assigned to group F or group P. Group F received an antibiotic therapy from day 1 to day 11 plus fenspiride (3 x 80mg/d from day 0 to day 30). Group P received the same antibiotic therapy plus placebo. Amoxicillin 500mg plus clavulanic acid 125, 3 tablets/day, was administered in both groups. Thirty-nine patients were included (group F 19 patients, group P 20 patients; 6 women and 33 men; mean age 61.1 +/- 9.8 years). The 3 Anthonisen criteria were present in 79% and 75% of the patients in group F and P respectively (NS). On day 11, expectoration resolved in 39% and 32% (NS) and cough in 44% and 16% (NS) of the patients in groups F and P respectively. Lung auscultation returned to normal in 83% of the patients in group F compared with 47% in group P (p=0.05). A composite clinical score including expectoration cough and auscultation findings showed that 28% of the patients in group F were symptom-free on day 11 compared with 0% in group P (p=0.04). On day 30, the two groups were comparable. In this preliminary study of patients with COPD presenting a bronchial superinfection, there was a significant improvement in lung auscultation and in the composite clinical score in patients given fenspiride. Fenspiride was thus found to

    Self-management support for chronic obstructive pulmonary disease (COPD) patients is recommended by UK national guidelines, but extent of implementation is unknown. We aimed to describe self-management behaviour and support among COPD patients and explore behaviour associated with having a self-management plan. We undertook cross-sectional analysis of self-reported data from diagnosed COPD patients in the Birmingham COPD Cohort study. Questionnaire items relevant to self-management behaviour, knowledge of COPD, receipt of self-management plans and advice from healthcare professionals were examined. Multiple regression models were used to identify behaviour associated with having a self-management plan. One-thousand seventy-eight participants (676 males, 62.7%, mean age 69.8 (standard deviation 9.0) years) were included. The majority reported taking medications as instructed (940, 94.0%) and receiving annual influenza vaccinations (962, 89.2%). Only 400 (40.4%) participants had self-management plans, 538 (49.9%) reported never having received advice on diet/exercise and 110 (42.7%) current smokers had been offered practical help to stop smoking in the previous year. General knowledge about COPD was moderate (mean total Bristol COPD Knowledge Questionnaire score: 31.5 (standard deviation 10.7); max score 65), corresponding to 48.5% of questions answered correctly. Having a self-management plan was positively associated with self-reported adherence to medication (odds ratio 3.10, 95% confidence interval 1.43 to 6.72), attendance at a training course (odds ratio 2.72, 95% confidence interval 1.81 to 4.12), attendance at a support group (odds ratio 6.28, 95% confidence interval 2.96 to 13.35) and better disease knowledge (mean difference 4.87, 95% confidence interval 3.16 to 6.58). Primary care healthcare professionals should ensure more widespread implementation of individualised self-management plans for all patients and improve the lifestyle advice provided. CALL FOR

    Highlights: • In the total lung field, AVI had excellent correlation with FEV{sub 1}/FVC. • AVI showed differences between three groups classified by the COPD severity. • In a lobe-based analysis, AVI did not mostly correlated with volume decrease ratio. • In a lobe-based analysis, coefficient of variation was relatively small in AVI. • In some lobes, AVI associated with the COPD severity despite respiratory level. - Abstract: Purpose: To determine the usefulness of newly-proposed index (attenuation–volume index, AVI: increase in mean value of lung attenuation (MVLA) divided by volume decrease ratio (VDR)) for quantitative assessment of lobar air trapping (LAT) using expiratory/inspiratory (E/I) computed tomography (CT) by minimizing influence of respiratory level. Materials and methods: Institutional review board approved study protocol. Twenty-one moderate or severe COPD (group A), 16 mild COPD (group B) and 26 normal volunteers (group C) underwent both E/I scans via 320-row CT and pulmonary functional test (PFT). Volume image data were automatically segmented into six lung lobes with minimal manual intervention. AVI, pixel index (PI), air trapping ratio (ATR) and relative volume change (RVC{sub 860–950}) were calculated in total lung (TL) and each lobe. Four indices in TL were correlated with both PFT result and VDR and those in TL and each lobe were compared between three groups. Results: Similar to ATR, AVI correlated with both FEV{sub 1}/FVC (r = 0.772, p < 0.01) and RV/TLC (r = −0.726, p < 0.01) and demonstrated a significant difference between three groups in both TL (group A: 1.69 ± 0.45, group B: 2.21 ± 0.45 and group C: 2.80 ± 0.44) and five lobes except for left lingular segment. In a lobe-based analysis regarding relationship with VDR, AVI was much less dependent than ATR, although regression lines of groups A and C were separated for AVI as well as ATR. Coefficient of variation of either PI or RVC{sub 860–950} was significantly

    Full Text Available Acute exacerbations in chronic onstructive pulmonary disease (COPD are common and systemic steroids play an important role in the management of these cases along with the bronchodilators. Nebulized budesonide is being used in the acute attacks of bronchial asthma either in children or in adults. But the role of nebulized steroids in acute exacerbation of COPD is not much studied in the literature. In this clinical review we have evaluated the role of nebulized corticosteroids in the management of acute exacerbation of COPD (AECOPD. Through Medline, Pubmed and Embase we analyzed the various studies that has been done to study the role of nebulized corticosteroids in the management of acute exacerbation of COPD. The key words used for the search criteria were: acute exacerbation, COPD, nebulized corticosteroids, budesonide, fluticasone. Only eight studies were found which had evaluated the role of nebulized corticosteroids in acute exacerbations of COPD. All these studies had used nebulized budesonide in AECOPD in different dosages, and had been compared with both either parental or oral steroids, and standard bronchodilator therapy. All the studies had found the clinical efficacy of nebulized budesonide to be of similar extent to that of either parental or oral steroids in AECOPD. Side effects profile of nebulized budesonide was minimal and acceptable as compared to systemic steroids. Nebulized budesonide may be an alternative to parental/oral prednisolone in the treatment of acute exacerbations of COPD but further studies should be done to evaluate its long-term impact on clinical outcomes after an initial episode of COPD exacerbation.

    Comorbidities are common in patients with chronic obstructive pulmonary disease (COPD), and have a significant impact on health status and prognosis. The PLATINO study provides data on self-reported comorbidities and perceived health status in COPD subjects. PLATINO is a population-based study on COPD prevalence in five Latin American cities. COPD diagnosis was defined by GOLD criteria (FEV1/FVCcerebrovascular disease, peptic ulcer and asthma. Health status was evaluated using the SF-12 questionnaire, derived from the question: «In general, would you say your health is excellent, very good, good, fair or poor?». A simple comorbidity score was calculated by adding the total number of comorbid conditions. Of a total population of 5314individuals, 759 had COPD. Reported comorbidities by decreasing frequency were: any cardiovascular disease, hypertension, peptic ulcer, heart disease, diabetes, cerebrovascular disease, asthma and lung cancer. COPD patients had a higher comorbidity score and prevalence of lung cancer (Pcerebrovascular disease (P=.0750). Factors associated with comorbidities were age, body mass index (BMI) and female gender. The number of comorbidities increased as the health status deteriorated. In the PLATINO population-based study, COPD individuals had an increased number of comorbidities. Age, female gender and higher BMI were the factors associated with comorbidity in these patients. Comorbid conditions were associated with impaired health status, independently of the COPD status. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

Using this software, we demonstrated in patients with COPD that FEV1 (%predicted was highly correlated with airway dimensions and the correlation coefficients improved as the airway became smaller in size (3. In this study, our aims are to further confirm the significant relationship between airway dimensions and airflow limitation in larger number of subjects, and to examine the relationship of airway dimensions with lung volumes in 95 patients with COPD (stage 0, 10; stage I, 23; stage II, 35; stage III, 24; stage IV, 3. We analyzed the airway dimensions from the 3rd to the 6th generations of the apical bronchus (B1 of the right upper lobe and the anterior basal bronchus (B8 of the right lower lobe. Lung volumes were measured by the helium closed circuit method. Both airway luminal area (Ai and wall area percent (WA% of all the generations, except a few, from the two bronchi were significantly correlated with RV and RV/TLC, but not with TLC or FRC. More importantly, the correlation coefficients (r between airway dimensions and RV/TLC improved as the airways became smaller in size from the 3rd to 6th generations in both bronchi (r = –0.483, –0482, –0.553, –0.624 for Ai of B8; r = 0.316, 0.380, 0.499, 0.551 for WA% of B8. These findings provide further evidence that distal (small airways rather than proximal (large airways are the determinants for airflow limitation in COPD.

    Chronic obstructive pulmonary disease (COPD) is commonly managed in primary care but there is poor awareness of evidence-based guidelines and the quality and interpretation of spirometry is suboptimal. The aims of this qualitative study were to explore how an intervention involving case finding and management of COPD was implemented, and the extent to which the GPs and practice nurses (PNs) worked in partnership to diagnose and manage COPD. Semi-structured interviews with PNs (n = 7), GPs (n = 4) and patients (n = 26) who had participated in the Primary care EarLy Intervention for Copd mANagement (PELICAN) study. The Theoretical Domains Framework was used to guide the coding and analysis of the interviews with PN and GPs. The patient interviews were analysed thematically. PNs developed technical skills and understood the requirements for good-quality spirometry. However, many lacked confidence in its interpretation and felt this was not part of their professional role. This was reflected in responses from the GPs. Once COPD was diagnosed, the GPs tended to manage the patients with the PNs less involved. This was in contrast with PNs' active role in managing patients with other chronic diseases such as diabetes. The extent to which the GPs and PNs worked in partnership to manage COPD varied. PNs improved their skills and confidence in performing spirometry. Beliefs about their professional role, identity and confidence influenced the extent to which PNs were involved in interpretation of the spirometry results and managing the patient in partnership with the GP. © The Author 2016.

    Work-related COPD occurs as a result of exposure to harmful particles and gases/fumes in the workplace, including among non-smokers. The objective of this article is to present more recent findings on the correlation between occupational exposure and COPD. In addition, we review diagnostic and prognostic considerations and the potential for prevention. We have undertaken literature searches in Medline and EMBASE for the period May 2009 - July 2014. Studies without any measurements of pulmonary function or references to occupational exposure were excluded. We have also included three prospective studies on pulmonary function and occupational exposure that were not indexed with the search terms used for obstructive pulmonary disease. Three population studies and eight studies that described a specific industry or sector were included. Recent studies detect an association between exposure and an increased risk of COPD in the construction industry, metallurgical smelting, cement production and the textile industry. In other respects, the findings from previous review studies are confirmed. Exposure to a number of organic and inorganic particles and fumes in the workplace may cause COPD even at prevailing levels of exposure. Doctors should inquire about such exposure in cases of suspected and established COPD and should have a low threshold for referral to occupational health assessment.

    Objectives: Structural and functional changes in pulmonary vessels are prevalent at the initial stages of chronic obstructive pulmonary disease (COPD). These vascular alterations can be assessed using cross-sectional area (CSA) of small pulmonary vessels. However, neither in non-COPD smokers nor in COPD patients it has been defined whether the structural changes of pulmonary vessels detected by paired inspiratory and expiratory CT scans are associated with emphysematous changes. We quantified the CSA and low attenuation area (LAA) and evaluated the changes in these parameters in the inspiratory and expiratory phases. Materials and methods: Fifty consecutive non-COPD smokers and COPD patients were subjected to multi detector-row CT and the percentage of vessels with a CSA less than 5 mm 2 as well as the percentage LAA for total lung area (%CSA < 5, %LAA, respectively) were calculated. Results: The %CSA < 5 correlated negatively with %LAA. The %CSA < 5 was lower in COPD patients with emphysema as compared with non-COPD smokers and COPD patients with or without mild emphysema. In addition, the %CSA < 5 was lower in the no/mild emphysema subgroup as compared with non-COPD smokers. The respiratory phase change of %CSA < 5 in COPD patients was greater than that in non-COPD smokers. Conclusion: The percentage of small pulmonary vessels decreased as emphysematous changes increase, and this decrease was observed even in patients with no/mild emphysema. Furthermore, respiratory phase changes in CSA were higher in COPD patients than in non-COPD smokers

Presence of comorbidities in COPD patients, and use of medications used to treat those comorbidities (non-COPD medications, may have an adverse impact on adherence to mCOPD medications. Objective: The objective of the study was to evaluate the association between non-adherence to mCOPD medications and non-COPD medications in COPD patients. Methods: COPD patients were identified using a large administrative claims database. Selected patients were 40–89 years old and continuously enrolled for 12 months prior to and 24 months after the first identified COPD diagnosis (index date during January 1, 2009 to December 31, 2010. Patients were required to have ≥1 prescription for a mCOPD medication within 365 days of the index date and ≥1 prescription for one of 12 non-COPD medication classes within ±30 days of the first COPD prescription. Adherence (proportion of days covered [PDC] was measured during 365 days following the first COPD prescription. The association between non-adherence (PDC <0.8 to mCOPD and non-adherence to non-COPD medications was determined using logistic regression, controlling for baseline patient characteristics. Results: A total of 14,117 patients, with a mean age of 69.9 years, met study criteria. Of these, 40.9% were males and 79.2% were non-adherent to mCOPD medications with a mean PDC of 0.47. Non-adherence to mCOPD medications was associated with non-adherence to 10 of 12 non-COPD medication classes (odds ratio 1.38–1

    Although there are studies evaluating the effects of periodontal health on chronic obstructive pulmonary disease (COPD), the effects of COPD - a systemic disease, on periodontal tissue is unknown. The aim of this study is to evaluate the effects of COPD on periodontal tissues by comparing COPD patients and controls. Fifty-two COPD patients and 38 non-COPD controls were included in this case-control study. Number of teeth, plaque index (PI), gingival index (GI), bleeding on probing, clinical attachment level and probing depth were included in the periodontal examination. In addition to clinical evaluations, gingival crevicular fluid (GCF) levels of high-sensitive C-reactive protein (hs-CRP), interleukin-1 beta (IL-lb) and prostaglandin-E2 (PGE2), and serum hs-CRP levels were measured in COPD patients and the controls. The number of teeth was significantly lower while PI and GI were significantly higher in COPD patients when compared to the controls. As well as serum hs-CRP levels, the GCF levels of hs-CRP, IL-1b and PGE2 were significantly higher in COPD patients than the controls. Our results demonstrated that COPD may be associated with periodontal disease as manifested by lower number of teeth and higher levels of inflammatory mediators especially CRP in GCF. This finding may be a reflection of systemic effects of COPD on periodontal tissues. Poor oral health behavior of COPD patients have to be considered in larger size group studies in the future.

    Objective: Wood smoke exposure is a risk factor for COPD. For a given degree of airway obstruction, the reduction in DLCO is smaller in individuals with wood smoke-related COPD than in those with smoking-related COPD, suggesting that there is less emphysema in the former. The objective of this study was to compare HRCT findings between women with wood smoke-related COPD and women with smoking-related COPD. Methods: Twenty-two women with severe COPD (FEV1/FVC ratio < 70% and FEV1 < 50%) were divided into two groups: those with wood smoke-related COPD (n = 12) and those with smoking-related COPD (n = 10). The two groups were compared regarding emphysema scores and airway involvement (as determined by HRCT); and functional abnormalities-spirometry results, DLCO, alveolar volume (VA), the DLCO/VA ratio, lung volumes, and specific airway resistance (sRaw). Results: There were no significant differences between the two groups in terms of FEV1, sRaw, or lung hyperinflation. Decreases in DLCO and in the DLCO/VA ratio were greater in the smoking-related COPD group subjects, who also had higher emphysema scores, in comparison with the wood smoke-related COPD group subjects. In the wood smoke-related COPD group, HRCT scans showed no significant emphysema, the main findings being peribronchial thickening, bronchial dilation, and subsegmental atelectasis. Conclusions: Female patients with severe wood smoke-related COPD do not appear to develop emphysema, although they do show severe airway involvement. The reduction in DLCO and VA, with a normal DLCO/VA ratio, is probably due to severe bronchial obstruction and incomplete mixing of inspired gas during the determination of single-breath DLCO.

    Prevention of exacerbations is a primary goal for chronic obstructive pulmonary disease (COPD) therapy. This randomized, double-blind, double-dummy, parallel-group, multicenter study evaluated the effect of budesonide/formoterol pressurized metered-dose inhaler (pMDI) versus formoterol dry powder inhaler (DPI) on reducing COPD exacerbations. 1219 patients aged ≥40 years with moderate-to-very-severe COPD (per lung function) and a history of ≥1 COPD exacerbation received budesonide/formoterol pMDI 320/9 μg twice daily (BID) during a 4-week run-in. Patients were then randomized 1:1 to receive budesonide/formoterol pMDI 320/9 μg BID (n = 606) or formoterol DPI 9 μg BID (n = 613) for 26 weeks. Exacerbations were identified using predefined criteria for symptom worsening and treatment with systemic corticosteroids and/or antibiotics and/or hospitalization. The primary endpoint was annual rate of exacerbations. Budesonide/formoterol pMDI resulted in a 24% reduction in annual rate of exacerbations (0.85 vs 1.12; rate ratio: 0.76 [95% CI: 0.62, 0.92]; P = 0.006), and a significant risk reduction for time to first exacerbation (hazard ratio: 0.78 [95% CI: 0.64, 0.96]; P = 0.016) versus formoterol DPI. The most commonly reported adverse events (AEs; ≥3%) in budesonide/formoterol and formoterol groups were COPD (4.5% vs 8.6%) and nasopharyngitis (5.0% vs 5.2%). Pneumonia AEs were reported in 0.5% and 1.0% of budesonide/formoterol-treated and formoterol-treated patients, respectively. Budesonide/formoterol pMDI is an effective treatment option for reducing exacerbation rates in COPD patients with moderate-to-very-severe airflow limitation and history of exacerbations. No increase in pneumonia was observed with budesonide/formoterol; safety data were consistent with its established profile. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Full Text Available Background: Chronic obstructive pulmonary disease (COPD has considerable effects on cardiac functions, including those of the right ventricle, left ventricle, and pulmonary blood vessels. Most of the increased mortality associated with COPD is due to cardiac involvement. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate the cardiac changes. Aims: To assess the cardiac changes secondary to COPD by echocardiography and to find out the correlation between echocardiographic findings and severity of COPD, if there is any. Materials and Methods: A total 40 of patients of COPD were selected and staged by pulmonary function test (PFT and evaluated by echocardiography. Results: On echocardiographic evaluation of COPD, 50% cases had normal echocardiographic parameters. Measurable tricuspid regurgitation (TR was observed in 27/40 cases (67.5%. Pulmonary hypertension (PH, which is defined as systolic pulmonary arterial pressure (sPAP > 30 mmHg was observed in 17/27 (63% cases in which prevalence of mild, moderate, and severe PH were 10/17 (58.82%, 4/17 (23.53%, and 3/17 (17.65%, respectively. The frequencies of PH in mild, moderate, severe, and very severe COPD were 16.67%, 54.55%, 60.00%, and 83.33%, respectively. Right atrial pressure was 10 mmHg in 82.5% cases and 15 mmHg in 17.5% cases. Cor pulmonale was observed in 7/17 (41.17% cases; 7.50% cases had left ventricle (LV systolic dysfunction and 47.5% cases had evidence of LV diastolic dysfunction defined as A ≥ E (peak mitral flow velocity of the early rapid filling wave (E, peak velocity of the late filling wave caused by atrial contraction (A on mitral valve tracing. Left ventricle hypertrophy was found in 22.5% cases. Conclusion : Prevalence of PH has a linear relationship with severity of COPD and severe PH is almost associated with cor pulmonale. Echocardiography helps in early detection of cardiac complications in COPD cases giving time for early

    Chronic obstructive pulmonary disease (COPD) is associated with low areal bone mineral density (aBMD) by dual-energy X-ray absorptiometry (DXA) and altered microstructure by bone histomorphometry and micro-computed tomography. Nevertheless, not all COPD patients sustain fragility fractures. In the present study, we used Raman microspectroscopic analysis to determine bone compositional properties at actively forming trabecular surfaces (based on double fluorescent labels) in iliac crest biopsies from 19 postmenopausal COPD patients (aged 62.1 ± 7.3 years). Additionally, we analyzed trabecular geometrical centers, representing tissue much older than the forming surfaces. Eight of the patients had sustained fragility fractures, and 13 had received treatment with inhaled glucocorticoids. None of the patients had taken oral glucocorticoids. The monitored parameters were mineral/matrix ratio (MM), nanoporosity, and relative glycosaminoglycan (GAG), lipid, and pyridinoline contents (PYD). There were no significant differences between the glucocorticoid-treated patients and those who did not receive any. On the other hand, COPD patients sustaining fragility fractures had significantly lower nanoporosity and higher MM and PYD values compared with COPD patients without fragility fractures. To the best of our knowledge, this is the first study to discriminate between fracture and non-fracture COPD patients based on differences in the material properties of bone matrix. Given that these bone material compositional differences are evident close to the cement line (a major bone interface), they may contribute to the inferior bone toughness and coupled with the lower lumbar spine bone mineral density values result in the fragility fractures prevalent in these patients. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

  18. Primary care COPD patients compared with large pharmaceutically-sponsored COPD studies: an UNLOCK validation study.

    Full Text Available BACKGROUND: Guideline recommendations for chronic obstructive pulmonary disease (COPD are based on the results of large pharmaceutically-sponsored COPD studies (LPCS. There is a paucity of data on disease characteristics at the primary care level, while the majority of COPD patients are treated in primary care. OBJECTIVE: We aimed to evaluate the external validity of six LPCS (ISOLDE, TRISTAN, TORCH, UPLIFT, ECLIPSE, POET-COPD on which current guidelines are based, in relation to primary care COPD patients, in order to inform future clinical practice guidelines and trials. METHODS: Baseline data of seven primary care databases (n=3508 from Europe were compared to baseline data of the LPCS. In addition, we examined the proportion of primary care patients eligible to participate in the LPCS, based on inclusion criteria. RESULTS: Overall, patients included in the LPCS were younger (mean difference (MD-2.4; p=0.03, predominantly male (MD 12.4; p=0.1 with worse lung function (FEV1% MD -16.4; p<0.01 and worse quality of life scores (SGRQ MD 15.8; p=0.01. There were large differences in GOLD stage distribution compared to primary care patients. Mean exacerbation rates were higher in LPCS, with an overrepresentation of patients with ≥ 1 and ≥ 2 exacerbations, although results were not statistically significant. Our findings add to the literature, as we revealed hitherto unknown GOLD I exacerbation characteristics, showing 34% of mild patients had ≥ 1 exacerbations per year and 12% had ≥ 2 exacerbations per year. The proportion of primary care patients eligible for inclusion in LPCS ranged from 17% (TRISTAN to 42% (ECLIPSE, UPLIFT. CONCLUSION: Primary care COPD patients stand out from patients enrolled in LPCS in terms of gender, lung function, quality of life and exacerbations. More research is needed to determine the effect of pharmacological treatment in mild to moderate patients. We encourage future guideline makers to involve primary care

    This paper was a report of the synthesis of evidence on examining the origins and definitions of the concept of resilience, investigating its application in chronic illness management and exploring its utility as a means of understanding family caregiving of adults with Chronic Obstructive Pulmonary Disease. Resilience is a concept that is becoming relevant to understanding how individuals and families live with illness, especially long-term conditions. Caregivers of adults with Chronic Obstructive Pulmonary Disease must be able to respond to exacerbations of the condition and may themselves experience cognitive imbalances. Yet, resilience as a way of understanding family caregiving of adults with COPD is little explored. Literature review - integrative review. CINAHL, PubMed, Google Scholar and EBSCO were searched between 1989-2015. The principles of rapid evidence assessment were followed. We identified 376 relevant papers: 20 papers reported the presence of the concept of resilience in family caregivers of chronic diseases patients but only 12 papers reported the presence of the concept of resilience in caregivers of Chronic Obstructive Pulmonary Disease patients and have been included in the synthesis. The term resilience in Chronic Obstructive Pulmonary Disease caregiving is most often understood using a deficit model of health.

    COPD (Chronic Obstructive Pulmonary Disease) is a serious lung disease which makes people hard to breathe. The number of people who have COPD is on the rise. COPD patients require lung function examinations and perform breathing exercises on a regular basis in order to be more aware of their lung functions, get diagnosed early, and control the shortness of their breaths. In order to help people with COPD, we developed mCOPD which is a smartphone based Android application made especially for C...

    The objective of the paper is to describe the burden of chronic obstructive pulmonary disease (COPD) in Latin America. Five Latin American cities were investigated, namely, Sao Paulo, Brazil; Mexico City, Mexico; Montevideo, Uruguay; Santiago, Chile; Caracas, Venezuela. This is a multi Centre study. Post-bronchodilator spirometry was used and the main outcome measure was FEV1/FVC < 0.7 (fixed ratio criterion). Global Obstructive Lung Disease (GOLD) stages were also analysed. The combined population aged {>=} 40 years in the five countries included in the study was approximately 85.3 million. Of these, it was estimated that 12.2 million have airflow obstruction, which corresponds to our prevalence estimate of 14.3%. The proportion of subjects in Stages II-IV of the GOLD classification was 5.6%. Risk factors presenting the highest actiological fractions for COPD were age, current smoking, indoor exposure to coal and exposure to dust in the workplace. Smoking, the modifiable factor with the strongest aetiological fraction for COPD, affects 29.2% of adults aged {>=} 40 years in these cities, corresponding to approximately 25 million smokers in this age group. Prevention of smoking and exposure to pollutants, such as coal and dust, are the interventions most likely to succeed against COPD in Latin America.

  2. Impact of exacerbations on COPD

    2010-06-01

    Full Text Available Exacerbations of chronic obstructive pulmonary disease (COPD determine disease-associated morbidity, mortality, resource burden and healthcare costs. Acute exacerbation care requirements range from unscheduled primary care visits to emergency room, inpatient or intensive care, generating significant costs in COPD. Even after an exacerbation resolves, respiratory, physical, social and emotional impairment may persist for prolonged time. Frequent exacerbations, mainly in patients with severe COPD, accelerate disease progression and mortality. Thus, patients with frequent exacerbations have a more rapid decline in lung function, worse quality of life and decreased exercise performance. Management of COPD directed to reduce incidence and severity of exacerbations improves long-term health status and conserves health care resources and costs.

    COPD is a heterogeneous disease defined by expiratory airflow limitation. Airflow limitation is caused by a variable combination of emphysematous destruction of lung parenchyma and small airway obstruction. Only advanced emphysema can be diagnosed by chest X-ray. Less severe emphysema and changes in small airways are commonly diagnosed by computed tomography. Typical visual appearance of pathologic changes in lung parenchyma and airways of COPD patients are presented, furthermore methods for quantitative assessment of these changes and the crucial role of imaging for surgical and bronchoscopic treatment in COPD are discussed.

    Purpose: To evaluate the hemodynamic changes in the extraocular orbital vessels of the patients with chronic obstructive pulmonary disease (COPD), using color Doppler ultrasonography (CDU) technique, and to compare the results with those of healthy control subjects. Methods: Forty-five patients with COPD and 17 healthy control subjects were included in this study. Patients with COPD were classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Fifteen patients of stage I COPD (mild airflow limitation), stage II COPD (worsening airflow limitation) or stage III COPD (severe airflow limitation) were enrolled into Group I, II and III, respectively. End tidal carbon dioxide (EtCO 2 ), peripheral oxygen saturation (SpO 2 ), pulse rate (PR) and respiratory rate (RR) were measured by using capnograph/pulse oximeter in all patients. Measurements were performed in only one randomly chosen eye of each participant. The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index (RI) were measured in the ophthalmic artery (OA), central retinal artery (CRA), lateral short posterior ciliary artery (LPCA) and medial short posterior ciliary artery (MPCA), using CDU technique. Results: The PSV measurements of the OA were significantly higher in Groups II and III compared to control group (p 2 with PSV (r = 0.53, p < 0.01) and EDV (r = 0.51, p < 0.01) of the OA. Statistically significant correlations were also found for the SpO2 with RI (r = -0.34, p < 0.05) in the OA. Conclusion: We concluded that COPD is associated with impaired retrobulbar hemodynamics, especially in the ophthalmic artery. Moreover, central retinal and posterior ciliary arteries with increased resistance are also found to be affected when compared with healthy control eyes

    Chronic obstructive pulmonary disease (COPD) may be work-related. It has been estimated that 15% of the population burden of COPD is attributable to occupational exposure. However, in Poland COPD is rarely recognized as an occupational disease. The aim of the study has been to analyze the causes of the low prevalence of work-related COPD in the context of the existing criteria as well as to analyze which part of the assessment - clinical or hygienic one - is responsible for such a low rate of occupational COPD recognitions. The study group included 150 patients hospitalized with a suspicion of occupational COPD. Each patient underwent a clinical examination, spirometry and reversibility test using bronchodilator. Moreover, hygienic evaluation of work conditions was performed in all the considered cases. In the case of the patients who fulfilled the criteria for COPD diagnosis in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) occupational origins of the disease, the disease was not recognized because 24.1% of the individuals did not meet spirometric criteria included in a definition of COPD in the Polish list of occupational diseases, while 27.8% of the individuals did not fulfill the criterion of a documented exposure to dusts and irritant gases. None of these criteria was fulfilled by 42.6% of the patients. In our country, both clinical and hygienic criteria result in limitations in recognition of occupational COPD. There is the need to establish new guidelines for the recognition of COPD as a compensable disease in Poland. Int J Occup Med Environ Health 2018;31(2):139-150.

    Prevention of COPD requires appropriate patient education, especially of adolescents, as well as the establishment of an effective national health policy. The new GOLD guidelines represent the current standard of knowledge on the management of chronic, progressive, obstructive pulmonary diseases. It points out that COPD is avoidable and treatable,and hence, there is no reason for therapeutic nihilism. Chronic bronchitis preceding a progressive respiratory obstruction cannot be improved with the presently available respiratory therapeutics. For this reason, therapeutic measures concentrate on the avoidance of exacerbations, which are primarily responsible for the severity of the course of COPD.

    Pain, commonly localized to the trunk in individuals with COPD, may be due to osteoporosis-related vertebral deformity and chest wall hyper-expansion causing misalignment of joints between the ribs and vertebrae. The purpose of this study was to determine if thoracic vertebral deformity and arthropathy were independent contributors to trunk pain in COPD patients compared to people with a significant smoking history. Participants completed the Brief Pain Inventory (BPI) on the same day as chest CT scans and spirometry. Current and ex-smokers were separated into COPD (n = 91) or non-COPD (n = 80) groups based on spirometry. Subsequently, CT images were assessed for thoracic vertebral deformity, bone attenuation values, and arthropathy of thoracic vertebral joints. The trunk area was the most common pain location in both COPD and non-COPD groups. Thoracic vertebral deformity and costotransverse joint arthropathy were independent contributors to trunk pain in COPD patients (adjusted OR = 3.55 and 1.30, respectively) whereas alcohol consumption contributed to trunk pain in the non-COPD group (adjusted OR = 0.35 in occasional alcohol drinkers; 0.08 in non-alcohol drinkers). The spinal deformity index and the number of narrowed disc spaces were significantly positively related to the BPI intensity, interference, and total scores significantly in COPD patients. Trunk pain, at least in part, is caused by thoracic vertebral deformity, and costotransverse and intervertebral arthropathy in patients living with COPD. The results of this study provided the foundation for the management of pain, which requires further exploration. Copyright © 2018 Elsevier Ltd. All rights reserved.

    One-third of patients with an exacerbation of Chronic Obstructive Pulmonary Disease(COPD) are re-hospitalised at 90 days. Exacerbation recovery is associated with reductions in lung hyperinflation and improvements in symptoms and physical activity. We assessed the feasibility of monitoring these clinical parameters in the home. We hypothesised that the degree of change in spirometry and lung volumes differs between those who had an uneventful recovery and those who experienced a further exacerbation. Hospitalised patients with an acute exacerbation of COPD referred for a supported discharge program participated in the study. Spirometry and Inspiratory Vital Capacity(IVC) were measured in the home at Days 1, 14 and 42 post-discharge. Patients also completed Medical Research Council(MRC), Borg and COPD Assessment Test(CAT) scores and were provided with a tri-axial accelerometer. Any new exacerbation events were recorded. Sixty-five patients with 72 exacerbation episodes were recruited. Fifty percent experienced a second exacerbation. Adequate IVC measurements were achieved by 90%, while only 70% completed spirometry. Uneventful recovery was accompanied by significant improvements in physiological measurements at day14, improved symptom scores and step count, p volumes, symptoms and step count following a COPD exacerbation may help to identify patients at risk of re-exacerbation. It is feasible to carry out these assessments in the home as part of a supported discharge programme. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Chronic Obstructive Pulmonary Disease (COPD) is now the fourth leading cause of death in the world. As COPD medications are associated with high mortality levels, continuous research into the improvement of treatment modalities is being conducted. This study aimed to identify the effects of acupoint-catgut embedment combined with medical treatment on the Body mass index, airflow Obstruction, Dyspnea and Exercise capacity (BODE) index scores of COPD patients. A single-blind randomized controlled trial was conducted on 48 patients; participants were allocated into either the acupoint-catgut embedment with medication group (case group) or the sham acupuncture with medication group (control group). Acupoint-catgut embedment was conducted at the BL13 Feishu, BL43 Gaohuangshu, BL20 Pishu, BL23 Shenshu, and ST40 Fenglong points two times at an interval of 15 days. The BODE index, a primary outcome indicator, was assessed on Day 1 and Day 30. The results showed statistically and clinically significant differences between the two groups—in fact, BODE index scores were reduced by 1.83 points in the case group (p = 0.000). Ultimately, BODE index scores were lower in the intervention group than in the control group, thus indicating a statistically significant and clinically important improvement of COPD-related symptoms. According to these results, acupoint-catgut embedment combined with medical treatment is concluded to be more effective than medical treatment alone in reducing BODE index scores.

    Patients with chronic obstructive pulmonary disease (COPD) have a higher prevalence of lung cancer. The chronic inflammation associated with COPD probably promotes the earliest stages of carcinogenesis. However, once tumors have progressed to malignancy, the impact of COPD on the tumor immune microenvironment remains poorly defined, and its effects on immune-checkpoint blockers' efficacy are still unknown. To study the impact of COPD on the immune contexture of non-small cell lung cancer (NSCLC). We performed in depth immune profiling of lung tumors by immunohistochemistry and we determined its impact on patients' survival (n=435). Tumor-infiltrating T lymphocyte (TILs) exhaustion by flow cytometry (n=50) was also investigated. The effectiveness of an anti-PD-1 treatment (nivolumab) was evaluated in 39 advanced-stage NSCLC patients. All data were analyzed according to patients' COPD status. Measurments and Main Results: Remarkably, COPD severity is positively correlated with the coexpression of PD-1/TIM-3 by CD8 T cells. In agreement, we observed a loss of CD8 T cell-associated favorable clinical outcome in COPD+ patients. Interestingly, a negative prognostic value of PD-L1 expression by tumor cells was observed only in highly CD8 T cell-infiltrated tumors of COPD+ patients. Finally, data obtained on 39 advanced-stage NSCLC patients treated by an anti-PD-1 antibody showed longer progression free survival in COPD+ patients, and also that the association between the severity of smoking and the response to nivolumab was preferentially observed in COPD+ patients. COPD is associated with an increased sensitivity of CD8 TILs to immune escape mechanisms developed by tumors, thus suggesting a higher sensitivity to PD-1 blockade in patients with COPD.

    Respiratory diseases including chronic-obstructive-pulmonary-disease (COPD) are globally increasing, with COPD predicted to become the third leading cause of global mortality by 2020. COPD is a heterogeneous disease with COPD-patients displaying different phenotypes as a result of a complex interaction between various genetic, environmental and life-style factors. In recent years, several investigations have been performed to better define such interactions, but the identification of the resulting phenotypes is still somewhat difficult, and may lead to inadequate assessment and management of COPD (usually based solely on the severity of airflow limitation parameter FEV1). In this new scenario, the management of COPD has been driven towards an integrative and holistic approach. The degree of complexity requires analyses based on large datasets (also including advanced functional genomic assays) and novel computational biology approaches (essential to extract information relevant for the clinical decision process and for the development of new drugs). Therefore, according to the emerging "systems/network medicine", COPD should be re.-evaluated considering multiple network(s) perturbations such as genetic and environmental changes. Systems Medicine (SM) platforms, in which patients are extensively characterized, offer a basis for a more targeted clinical approach, which is predictive, preventive, personalized and participatory ("P4-medicine"). It clearly emerges that in the next future, new opportunities will become available for clinical research on rare COPD patterns and for the identification of new biomarkers of comorbidity, severity, and progression. Herein, we overview the literature discussing the opportunity coming from the adoption of SMapproaches in COPD management, focusing on proteomics and metabolomics, and emphasizing the identification of disease sub-clusters, to improve the development of more effective therapies.

    Exacerbations constitute a major cause of morbidity and mortality in patients suffering from chronic obstructive pulmonary disease (COPD). Both bacterial infections, such as those with non-typeable Haemophilus influenzae (NTHi), and exposures to diesel engine emissions are known to contribute to exacerbations in COPD patients. However, the effect of diesel exhaust (DE) exposure on the epithelial response to microbial stimulation is incompletely understood, and possible differences in the response to DE of epithelial cells from COPD patients and controls have not been studied. Primary bronchial epithelial cells (PBEC) were obtained from age-matched COPD patients (n = 7) and controls (n = 5). PBEC were cultured at the air-liquid interface (ALI) to achieve mucociliary differentiation. ALI-PBECs were apically exposed for 1 h to a stream of freshly generated whole DE or air. Exposure was followed by 3 h incubation in presence or absence of UV-inactivated NTHi before analysis of epithelial gene expression. DE alone induced an increase in markers of oxidative stress (HMOX1, 50-100-fold) and of the integrated stress response (CHOP, 1.5-2-fold and GADD34, 1.5-fold) in cells from both COPD patients and controls. Exposure of COPD cultures to DE followed by NTHi caused an additive increase in GADD34 expression (up to 3-fold). Importantly, DE caused an inhibition of the NTHi-induced expression of the antimicrobial peptide S100A7, and of the chaperone protein HSP5A/BiP. Our findings show that DE exposure of differentiated primary airway epithelial cells causes activation of the gene expression of HMOX1 and markers of integrated stress response to a similar extent in cells from COPD donors and controls. Furthermore, DE further increased the NTHi-induced expression of GADD34, indicating a possible enhancement of the integrated stress response. DE reduced the NTHi-induced expression of S100A7. These data suggest that DE exposure may cause adverse health effects in part by

    Self-treatment of acute exacerbations of COPD with antibiotics and/or oral corticosteroids has emerged as a promising strategy to reduce hospitalization rates, mortality and health costs. However, for reasons little understood, the effect of self-treatment, particularly when not part of comprehensive self-management programs, remains unclear. Therefore, this study aims to get insight into the patients' perspective on self-treatment of acute exacerbations of COPD, focusing specifically on how patients decide for the right moment to start treatment with antibiotics and/or oral corticosteroids, what they consider important when making this decision and aspects which might interfere with successful implementation. We interviewed 19 patients with chronic obstructive pulmonary disease using qualitative semi-structured interviews, and applied thematic analysis for data analysis. Patients were well equipped with experiential knowledge to recognize and promptly respond to worsening COPD symptoms. Worries regarding potential adverse effects of antibiotics and oral corticosteroids played an important role in the decision to start treatment and could result in hesitation to start treatment. Although self-treatment represented a practical and appreciated option for some patients with predictable symptom patterns and treatment effect, all patients favoured assistance from a medical professional when their perceived competence reached its limits. However, a feeling of obligation to succeed with self-treatment or distrust in their doctors or the health care system could keep patients from timely help seeking. COPD patients regard self-treatment of exacerbations with antibiotics and/or oral corticosteroids as a valuable alternative. How they engage in self-treatment depends on their concerns regarding the medications' adverse effects as well as on their understanding of and preferences for self-treatment as a means of health care. Caregivers should address these perspectives in a

    Chronic Obstructive Pulmonary Disease (COPD) is a disorder resulting from an interaction between a genetic predisposition, still poorly understood, and the impact of environmental factors including tobacco smoke or professional or domestic air contaminants. The prevalence of COPD in the world concerns women as much as men, but it remains under diagnosed among women smokers. The mortality data show an increase in mortality among women compared to men. It thus seems that COPD in women presents more often a particular phenotype, characterized more by bronchial attacks than by emphysema, and by more marked functional effects on the quality of life. Anxiety and depression seem more marked with further repercussions on the quality of life. The effectiveness of treatment may be different, in particular with regard to nicotine weaning and respiratory rehabilitation. In the evaluation of chronic diseases in women little is known about COPD. Further studies, focusing specifically on these differences, are needed in order to improve the diagnosis and management of COPD in women. Copyright 2010 SPLF. Published by Elsevier Masson SAS.

    Polyvalent mechanical bacterial lysates (PMBLs) have been shown to reduce the number of infectious episodes in patients with recurrent infections of the respiratory tract. Some previous investigations have also shown the effectiveness of PMBLs in reducing exacerbations of chronic obstructive pulmonary disease (COPD). The AIACE study, which was developed according to criteria of evidence-based medicine, evaluated whether the administration of PMBLs to COPD patients, in addition to the recommended treatment, was able to reduce the number of exacerbations by 25%. Two hundred eighty-eight patients with moderate to very severe COPD were recruited and randomly assigned to either placebo or PMBLs. The placebo or PMBLs were administered according to the standard scheme. The primary outcome of the study was not achieved. However, the number of days with fever (21 days per year versus 40.15; p < 0.001), the days of hospitalisation (65 days vs 162 days; p < 0.001), the interval between the first and second exacerbations (123.89 days vs 70.36; p = 0.03) and the number of days in poor health (109 days/year vs 171 days/year; p < 0.001) were significantly better in the PMBL group than in the placebo group. In conclusion, the results of this trials showed that Ismigen, in addition to guideline-suggested treatment, could not significantly reduce the number of exacerbations in the considered population; nevertheless, the secondary outcome results demonstrated potential benefits of this compound for relevant clinical outcomes.

    Chronic obstructive pulmonary disease (COPD) is a significant clinical problem wich is dependent on many environmental factors. of the study was to present a characteristic of examined group in the moment of including into the project. Based on data obtained from studies conducted in six medical universities in Poland we present the characteristics of 445 patients (M-69%), median age 66.2 years, suffering from COPD with median disease duration 7.7 years. The analysis included: age, education, risk factors, exacerbations and hospitalizations, comorbidities, severity of the disease, drug use and the results of selected tests and the quality of life of patients in relation with their place of residence. Some differences were found among the participating centers. The youngest patients came from Wrocław and the oldest from Katowice. The largest number of patients with higher education were from Warsaw, while the lowest number was noted in Poznań; patients with primary education were most numerous in Lublin. Patients from Warsaw had the highest number of pack-years, smoking history was least relevant in patients from Wrocław. The highest values of spirometrical parameters were observed in Gdańsk, while the lowest--in Poznań. COPD treatment mainly comprised of long-acting beta2 agonists, followed by anticholinergic agents, more than 50% of patients were treated with inhaled glucocorticosteroids. The most common comorbidities were cardiovascular diseases. The study group showed characteristics similar to those of other cohorts of patients with COPD described in the literature, but we found some differences between patients from different centers which participated in the study. © 2015 MEDPRESS.

To reduce the number of screenings, it may be of value to define subgroups with a higher prevalence of AAA. Since chronic obstructive pulmonary disease (COPD and AAA are associated with several common risk factors, this study investigates the prevalence of AAA in COPD patients.Patients and methods: Patients with COPD were identified via the hospital information system. Inclusion criteria were: COPD stage I–IV, ability to give full consent, and age >18 years; exclusion criteria were: patient too obese for an ultrasound check, previously diagnosed AAA, prior surgery for AAA, or ethical grounds such as concomitant advanced malignant or end-stage disease. The primary endpoint of the study was an aortic diameter measured by ultrasound of ≥30 mm. Defined secondary endpoints were evaluated on the basis of medical records and interviews.Results: Of the 1,180 identified COPD patients, 589 were included in this prospective study. In 22 patients (3.70%, the aortic diameter was ≥30 mm, representing an AAA prevalence of 6.72% among males aged >65 years. The risk of AAA increased with the following comorbidities/risk factors: male sex (odds ratio [OR] 2.98, coronary heart disease (OR 2.81, peripheral arterial occlusive disease (OR 2.47, hyperlipoproteinemia (OR 2.77, AAA in the family history (OR 3.95, and COPD stage I/II versus IV (OR 1.81.Conclusion: The overall AAA prevalence of 3.7% in our group of COPD patients is similar to that of the general population aged >65

Objective: To evaluate the distribution of BMI among subjects with COPD in the general population of the MENA region. Methods: This study was a subanalysis of the BREATHE study, a cross-sectional survey of COPD conducted in the general population of ten countries in the MENA region and Pakistan. The study population consisted of subjects screened for COPD who documented their weight and height. A COPD questionnaire was administered to subjects who screened positively for COPD in order to collect data on patient characteristics, symptom severity, management and burden of disease, comorbidities, and health care resource utilization and data allowing calculation of the BMI. The COPD Assessment Test (CAT was administered to those screened positively for COPD to collect data on the impact of respiratory symptoms. Results: Nine hundred and ninety-six subjects with COPD, who completed the detailed COPD questionnaire and documented their weight and height, were included in this analysis. The mean BMI was 27.7±5.7 kg/m2. The proportion of COPD patients with a BMI ≥25 kg/m2 is significantly higher than the proportion with a BMI <25 kg/m2 (64.6% [n=643] vs 35.4% [n=353], respectively; P<0.0001.

    Full Text Available Claudio Tantucci, Denise ModinaUnit of Respiratory Medicine, Department of Medical and Surgical Sciences, University of Brescia, Brescia, ItalyAbstract: The landmark study of Fletcher and Peto on the natural history of tobacco smoke-related chronic airflow obstruction suggested that decline in the forced expiratory volume in the first second (FEV1 in chronic obstructive pulmonary disease (COPD is slow at the beginning, becoming faster with more advanced disease. The present authors reviewed spirometric data of COPD patients included in the placebo arms of recent clinical trials to assess the lung function decline of each stage, defined according to the severity of airflow obstruction as proposed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD guidelines. In large COPD populations the mean rate of FEV1 decline in GOLD stages II and III is between 47 and 79 mL/year and 56 and 59 mL/year, respectively, and lower than 35 mL/year in GOLD stage IV. Few data on FEV1 decline are available for GOLD stage I. Hence, the loss of lung function, assessed as expiratory airflow reduction, seems more accelerated and therefore more relevant in the initial phases of COPD. To have an impact on the natural history of COPD, it is logical to look at the effects of treatment in the earlier stages.Keywords: chronic obstructive pulmonary disease, decline, forced expiratory volume in 1 second, FEV1

    This special issue of Patient Education and Counseling is long overdue. During most of the last two decades asthma, and notably asthma self-management has been in the spotlight, while COPD has had to endure a nihilistic approach. The first sign that interest was shifting to the treatment of COPD came from a few large randomized trials on the use of inhaled corticosteroids (ICS) in COPD. Although these studies demonstrated a moderate effect of ICS in COPD, it has become clear that true improvements in the management of this chronic disease will have to come from behavioral interventions. This special issue of Patient Education and Counseling is dedicated solely to the non-pharmaceutical management of COPD. It addresses many issues related to behavioral therapy, such as smoking cessation, exercise training, nutritional aspects, and self-management programs, including action plans to self-treat exacerbations. With the availability of all the treatment and management options, described in this special issue, a nihilistic attitude toward the patient with COPD is no longer justified.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a respiratory disease that results in progressive airflow limitation and respiratory distress. Physiopathological features of COPD suggest that people who suffer from this disease have many risk factors for falls that have been identified in older individuals. The aim of the study was to compare and quantify functional balance between COPD patients and healthy subjects; to investigate the risk of falls in acute stages of the disease and to identify risk factors that could lead to falls.We studied 46 patients with moderate-severe COPD (29 stable and 17 in acute exacerbation--AECOPD and 17 healthy subjects (control group having similar demographic data. We analyzed the difference in Berg Balance Scale (BBS, Single Leg Stance (SLS and Timed Up and Go test (TUG between these three groups and the correlation of these scores with a number of incriminatory factors.The presence of COPD was associated with significant worsening of balance tests: BBS (55 control, vs. 53 COPD, vs. 44 AECOPD points p<0.001, TUG (8.6 control vs. 12.3 COPD vs. 15.9 AECOPD seconds. p<0.001, SLS (31.1 control vs. 17.7 COPD vs. 7.2 AECOPD seconds p<0.001 which may be associated with an increased risk of falls. Anxiety and depression were significantly associated with decreased balance test scores; anxiety (2 control vs. 6 COPD vs. 9 AECOPD points p<0.001 depression (2 control vs. 7 COPD vs. 12 AECOPD points p<0.001.According to our results COPD patients in moderate-severe stages and especially those in exacerbation have a high risk of falls.

The aim of the present study was to determine the prevalence of COPD in patients with cerebral and/or peripheral artery disease and to assess factors associated with the presence of COPD. Following the diagnosis of cerebral and/or peripheral artery disease by means of duplex sonography, 166 consecutive patients underwent body plethysmography with capillary blood gas analysis. Thereafter, blood tests with determination of different parameters such as lipid profile, inflammatory and coagulation markers were conducted in remaining 136 patients who fulfilled inclusion criteria of the study. Thirty-six out of 136 patients suffered from COPD, mostly in early stages of the disease. Residual volume indicating emphysema was increased (162.9%±55.9% vs 124.5%±37.0%, p<0.05 and diffusion capacity was decreased (55.1%±19.5% vs 75.3%±18.6%, p<0.05 in COPD patients vs non-COPD group. In capillary blood gas analysis, COPD patients had lower partial pressure of oxygen (70.9±11.5 vs 75.2±11.0 mmHg, p<0.05 and higher partial pressure of carbon dioxide (36.8±7.5 vs 34.4±4.4 mmHg, p<0.05 compared with non-COPD individuals. Presence of COPD was associated with predominance of diabetes mellitus, interleukin-8-related systemic neutrophilic inflammation and anemia. In conclusion, COPD is highly prevalent in patients with atherosclerotic artery disease.

    Full Text Available The conventional medical management of emphysema using bronchodilators and anti-inflammatory agents has a limited benefit in patients having advanced hyperinflation of lungs due to destruction of elastic tissue. The natural course of Chronic Obstructive Pulmonary Disease (COPD has been shown to be altered by only smoking cessation and oxygen therapy so far. The lung volume reduction surgery is viewed as another modality to change the natural history of emphysema in recent years. For patients with more generalized emphysema, resection of lung parenchyma improves elastic recoil and chest wall mechanics. An extensive literature search has demonstrated that carefully selected patients of emphysema (i.e. upper lobe predominant disease, low exercise capacity and Forced Expiratory Volume in First Second (FEV1 and DLco and #8804; 20% of predicted receive benefits in terms of symptomatic improvement and physiologic response following Lung Volume Reduction Surgery (LVRS. The resurgent interest in LVRS and National Emphysema Treatment Trial findings for emphysema have stimulated a range of innovative methods, to improve the outcome and reduce complications associated with current LVRS techniques. These novel approaches include surgical resection with compression/banding devices, endobronchial blockers, sealants, obstructing devices and valves and endobronchial bronchial bypass approaches. Experimental data and preliminary results are becoming available for some of these approaches. Most of the published studies so far have been uncontrolled and unblinded. Overall, extensive research in the near future will help to determine the potential clinical applicability of these new approaches to the treatment of emphysema symptoms.

    Chronic obstructive pulmonary disease (COPD) is a slowly progressive disease characterized by airflow limitation, cough, sputum production, and, at later stages, dyspnea. COPD is currently the fourth-leading cause of mortality and the twelfth-leading cause of disability, and by the year 2020 it is expected to be the third-leading cause of death and the fifth-leading cause of disability worldwide. The diagnosis of COPD largely relies on a history of exposure to noxious stimuli and abnormal lung function test results. Since the pathology of COPD varies and the molecular mechanisms are only slightly understood, the diagnosis and stage assessment of COPD have relied on the results of pulmonary function test. In addition, CT and nuclear medicine study are utilized for assessment of regional morphological and functional abnormalities. Recently, pulmonary functional MR imaging is suggested as a new technique for assessment of regional physiopathologic information in various pulmonary diseases including COPD, pulmonary thromboembolism, lung cancer and interstitial lung diseases. This review article covers the brief description of theory and clinical application of contrast-enhanced perfusion MR imaging; hyperpolarized noble gas MR imaging and oxygen-enhanced MR imaging in COPD subjects. We believe that further basic studies as well as clinical applications of this new technique will define the real significance of pulmonary functional MR imaging for the future of pulmonary functional imaging and its usefulness for diagnosis and patients' management in COPD.

    The literature of acute exacerbation of chronic obstructive pulmonary disease (COPD) is fast expanding. This review focuses on several aspects of acute exacerbation of COPD (AECOPD) including epidemiology, diagnosis and management. COPD poses a major health and economic burden in the Asia-Pacific region, as it does worldwide. Triggering factors of AECOPD include infectious (bacteria and viruses) and environmental (air pollution and meteorological effect) factors. Disruption in the dynamic balance between the 'pathogens' (viral and bacterial) and the normal bacterial communities that constitute the lung microbiome likely contributes to the risk of exacerbations. The diagnostic approach to AECOPD varies based on the clinical setting and severity of the exacerbation. After history and examination, a number of investigations may be useful, including oximetry, sputum culture, chest X-ray and blood tests for inflammatory markers. Arterial blood gases should be considered in severe exacerbations, to characterize respiratory failure. Depending on the severity, the acute management of AECOPD involves use of bronchodilators, steroids, antibiotics, oxygen and noninvasive ventilation. Hospitalization may be required, for severe exacerbations. Nonpharmacological interventions including disease-specific self-management, pulmonary rehabilitation, early medical follow-up, home visits by respiratory health workers, integrated programmes and telehealth-assisted hospital at home have been studied during hospitalization and shortly after discharge in patients who have had a recent AECOPD. Pharmacological approaches to reducing risk of future exacerbations include long-acting bronchodilators, inhaled steroids, mucolytics, vaccinations and long-term macrolides. Further studies are needed to assess the cost-effectiveness of these interventions in preventing COPD exacerbations. © 2016 Asian Pacific Society of Respirology.

    The employment of systemic corticosteroids in the treatment of acute exacerbations of chronic obstructive pulmonary disease (COPD) has been shown to improve airway limitation, decrease treatment failure and risk of relapse, and may improve symptoms in addition to decreasing the length of hospital stay. Nowadays, all clinical guidelines recommend systemic corticosteroids to treat moderate or severe COPD exacerbations. However, their use is associated with potential side effects, mainly hyperglycemia. In the era of precision medicine, the possibility of employing blood eosinophil count has emerged as a potential way of optimizing therapy. Issues regarding the intra-individual variability of blood eosinophil count determination, a lack of clear data regarding the real prevalence of eosinophilic acute exacerbations, the fact that previously published studies have demonstrated the benefit of systemic corticosteroids irrespective of eosinophil levels, and especially the fact that there is only one well-designed study justifying this approach have led us to think that we are not ready to use eosinophil count to guide treatment with systemic corticosteroids during acute exacerbations of COPD.

The primary goal of this trial is to investigate if treatment with antiplatelet therapy will produce the required response in platelet function measured using the Multiplate test in patients with COPD. Patients with COPD are screened for eligibility using inclusion and exclusion criteria. Eligible patients are randomised and allocated into one of four groups to receive aspirin plus placebo, ticagrelor plus placebo, aspirin plus ticagrelor or placebo only. Markers of systemic inflammation, platelet reactivity, arterial stiffness, carotid intima-media thickness (CIMT), lung function and quality of life questionnaires are assessed. The primary outcome consists of inhibition (binary response) of aspirin and ADP-induced platelet function at 6 months. Secondary outcomes include changes in inflammatory markers, CIMT, non-invasive measures of vascular stiffness, quality of life using questionnaires (EuroQol-five dimensions-five levels of perceived problems (EQ5D-5L), St. George's COPD questionnaire) and to record occurrence of repeat hospitalisation, angina, myocardial infarction or death from baseline to 6 months. Safety outcomes will be rates of major and minor bleeding, forced expiratory volume in 1 s, forced vital capacity and Medical Research Council dyspnoea scale. The study was approved by the North East-Tyne and Wear South Research Ethics Committee (15/NE/0155). Findings of the study will be presented in scientific sessions and published in peer-reviewed journals.

    Objectives: Dynamic hyperinflation (DH) significantly affects dyspnea and intolerance to exercise in patients with chronic obstructive pulmonary disease (COPD). Quantitative computed tomography (QCT) of the chest is the modality of choice for quantification of the extent of anatomical lung damage in patients with COPD. The purpose of this article is to assess the effects of DH on QCT measurements. Methods: The study sample comprised patients with Global initiative for Chronic Obstructive Lung Disease (GOLD) stages III and IV COPD referred for chest CT. We examined differences in total lung volume (TLV), emphysema volume (EV), and emphysema index (EI) determined by QCT before and after DH induction by metronome-paced tachypnea (MPT). Initial (resting) and post-MPT CT examinations were performed with the same parameters. Results: Images from 66 CT scans (33 patients) were evaluated. EV and EI, but not TLV, increased significantly (p < 0.0001) after DH induction. Conclusion: QCT showed significant increases in EV and EI after MPT-induced DH in patients with GOLD stages III and IV COPD. For longitudinal assessment of patients with COPD using QCT, we recommend the application of a pre-examination rest period, as DH could mimic disease progression. QCT studies of the effects of DH-preventive therapy before exercise could expand our knowledge of effective measures to delay DH-related progression of COPD.

    This study aims to (1) examine the variation in implementation of a 2-year chronic obstructive pulmonary disease (COPD) management programme called RECODE, (2) analyse the facilitators and barriers to implementation and (3) investigate the influence of this variation on health outcomes. Implementation variation among the 20 primary-care teams was measured directly using a self-developed scale and indirectly through the level of care integration as measured with the Patient Assessment of Chronic Illness Care (PACIC) and the Assessment of Chronic Illness Care (ACIC). Interviews were held to obtain detailed information regarding the facilitators and barriers to implementation. Multilevel models were used to investigate the association between variation in implementation and change in outcomes. The teams implemented, on average, eight of the 19 interventions, and the specific package of interventions varied widely. Important barriers and facilitators of implementation were (in)sufficient motivation of healthcare provider and patient, the high starting level of COPD care, the small size of the COPD population per team, the mild COPD population, practicalities of the information and communication technology (ICT) system, and hurdles in reimbursement. Level of implementation as measured with our own scale and the ACIC was not associated with health outcomes. A higher level of implementation measured with the PACIC was positively associated with improved self-management capabilities, but this association was not found for other outcomes. There was a wide variety in the implementation of RECODE, associated with barriers at individual, social, organisational and societal level. There was little association between extent of implementation and health outcomes.

    This present paper describes the method and the organization of the study known as the COPD History Assessment In SpaiN (CHAIN), whose main objective is to evaluate the long-term natural history of a chronic obstructive pulmonary disease (COPD) patient cohort from a multidimensional standpoint and to identify clinical phenotypes, in comparison with another non-COPD control cohort. CHAIN is a multicenter, observational study of prospective cohorts carried out at 36 Spanish hospitals. Both cohorts will be followed-up during a 5-year study period with complete office visits every 12 months and telephone interviews every 6 months in order to evaluate exacerbations and the vital state of the subjects. The recruitment period for cases was between 15 January 2010 and 31 March 2012. At each annual visit, information will be collected on: (i) clinical aspects (socio-economic situation, anthropometric data, comorbidities, smoking, respiratory symptoms, exacerbations, quality of life, anxiety-depression scale, daily life activities, treatments); (ii) respiratory function (spirometry, blood gases, hyperinflation, diffusion, respiratory pressures); (iii) BODE index (main study variable); (iv) peripheral muscle function, and (v) blood work-up (including IgE and cardiovascular risk factors). In addition, a serum bank will be created for the future determination of biomarkers. The data of the patients are anonymized in a database with a hierarchical access control in order to guarantee secure information access. The CHAIN study will provide information about the progression of COPD and it will establish a network of researchers for future projects related with COPD. Copyright © 2012 SEPAR.

    Full Text Available Evidence of the adverse health effects attributable to second-hand smoke (SHS exposure is available. This study aims to quantify the impact of SHS exposure on ischaemic heart diseases (IHD, chronic obstructive pulmonary diseases (COPD, and stroke in Germany. Therefore, this study estimated and forecasted the morbidity for the three outcomes in the German population. Furthermore, a health impact assessment was performed using DYNAMO-HIA, which is a generic software tool applying a Markov model. Overall 687,254 IHD cases, 231,973 COPD cases, and 288,015 stroke cases were estimated to be attributable to SHS exposure in Germany for 2014. Under the assumption that the population prevalence of these diseases and the prevalence of SHS exposure remain constant, the total number of cases will increase due to demographic aging. Assuming a total eradication of SHS exposure beginning in 2014 leads to an estimated reduction of 50% in cases, compared to the reference scenario in 2040 for all three diseases. The results highlight the relevance of SHS exposure because it affects several chronic disease conditions and has a major impact on the population’s health. Therefore, public health campaigns to protect non-smokers are urgently needed.

    Introduction Chemokine (C-C motif) ligand 18 (CCL-18) has been shown to be elevated in chronic obstructive pulmonary disease (COPD) patients. This study primarily aimed to evaluate whether the serum CCL-18 level differentiates the frequent exacerbator COPD phenotype from infrequent exacerbators. The secondary aim was to investigate whether serum CCL-18 level is a risk factor for exacerbations requiring hospitalization. Materials and methods Clinically stable COPD patients and participants with smoking history but normal spirometry (NSp) were recruited for the study. Modified Medical Research Council Dyspnea Scale, COPD Assessment Test, spirometry, and 6-min walking test were performed. Serum CCL-18 levels were measured with a commercial ELISA Kit. Results Sixty COPD patients and 20 NSp patients were recruited. Serum CCL-18 levels were higher in COPD patients than those in NSp patients (169 vs 94 ng/mL, PCOPD (168 vs 196 ng/mL) subgroups did not achieve statistical significance (P=0.09). Serum CCL-18 levels were significantly higher in COPD patients who had experienced at least one exacerbation during the previous 12 months. Overall, ROC analysis revealed that a serum CCL-18 level of 181.71 ng/mL could differentiate COPD patients with hospitalized exacerbations from those who were not hospitalized with a 88% sensitivity and 88.2% specificity (area under curve: 0.92). Serum CCL-18 level had a strong correlation with the frequency of exacerbations requiring hospitalization (r=0.68, PCOPD, as it is associated with frequency of exacerbations, particularly with severe COPD exacerbations requiring hospitalization, as well as with functional parameters and symptom scores.

    Studies report high in-hospital and post-discharge mortality of chronic obstructive pulmonary disease (COPD) exacerbations varying depending upon patient characteristics, hospital resources and treatment standards. This study aimed to investigate the patient, resource and organisational factors associated with in-hospital and 90-day post-discharge mortality and readmission of COPD exacerbations within the European COPD Audit. The audit collected data of COPD exacerbation admissions from 13 European countries.On admission, only 49.7% of COPD patients had spirometry results available and only 81.6% had blood gases taken. Using logistic regression analysis, the risk associated with in-hospital and post-discharge mortality was higher age, presence of acidotic respiratory failure, subsequent need for ventilatory support and presence of comorbidity. In addition, the 90-day risk of COPD readmission was associated with previous admissions. Only the number of respiratory specialists per 1000 beds, a variable related to hospital resources, decreased the risk of post-discharge mortality.The European COPD Audit identifies risk factors associated with in-hospital and post-discharge mortality and COPD readmission. Addressing the deficiencies in acute COPD care such as making spirometry available and measuring blood gases and providing noninvasive ventilation more regularly would provide opportunities to improve COPD outcomes.

COPD is associated with worsening airflow limitation over time and increased frequency of COPD exacerbations, leading to increased mortality and morbidity. The effects of COPD extend beyond the lungs, as multiple comorbidities may occur with COPD, including cardiovascular disease, diabetes mellitus, osteoporosis, depression, and pneumonia. COPD exacerbations are associated with a rapid worsening of baseline symptoms that requires prompt management and may necessitate hospitalization in the case of a severe episode. Patients with COPD exacerbations require urgent management of symptoms to prevent further worsening, and preventative steps may be taken to help reduce the number and frequency of future exacerbations. Roflumilast is a potent and selective inhibitor of the enzyme phosphodiesterase-4 that targets the systemic inflammation associated with COPD. Roflumilast has a variety of anti-inflammatory effects including decreasing inflammatory mediators and the expression of cell surface markers and inhibition of apoptosis. Several clinical trials evaluating roflumilast in the treatment of COPD have demonstrated significant improvements from baseline versus placebo in lung function, including increases in mean pre- and postbronchodilator forced expiratory volume in 1 second and forced vital capacity. Data suggest that roflumilast reduces moderate to

    Background: Studies have shown that family history is a risk factor for COPD, but have not accounted for family history of smoking. Therefore, we sought to identify the effects of family history of smoking and family history of COPD on COPD susceptibility. Methods: We compared 821 patients with COPD to 776 control smokers from the Genetic Epidemiology of COPD (COPDGene) Study. Questionnaires captured parental histories of smoking and COPD, as well as childhood environmental tobacco smoke (ETS) exposure. Socioeconomic status was defined by educational achievement. Results: Parental history of smoking (85.5% case patients, 82.9% control subjects) was more common than parental history of COPD (43.0% case patients, 30.8% control subjects). In a logistic regression model, parental history of COPD (OR, 1.73; P < .0001) and educational level (OR, 0.48 for some college vs no college; P < .0001) were significant predictors of COPD, but parental history of smoking and childhood ETS exposure were not significant. The population-attributable risk from COPD family history was 18.6%. Patients with COPD with a parental history had more severe disease, with lower lung function, worse quality of life, and more frequent exacerbations. There were nonsignificant trends for more severe emphysema and airway disease on quantitative chest CT scans. Conclusions: Family history of COPD is a strong risk factor for COPD, independent of family history of smoking, personal lifetime smoking, or childhood ETS exposure. Although further studies are required to identify genetic variants that influence COPD susceptibility, clinicians should question all smokers, especially those with known or suspected COPD, regarding COPD family history.

    Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and may frequently be associated with sleep disturbances. However, the correlates of insomnia in COPD patients have not been well characterized. The aim of the current study was to describe the prevalence of insomnia disorder in COPD and to elucidate the demographic and clinical characteristics of COPD patients that are associated with insomnia. Cross-sectional study. Clinic-based sample from an academic hospital. Patients with stable COPD. An interviewer-conducted survey was administered to 183 participants with COPD. Seventy-two of these participants (30 with and 42 without insomnia) maintained a sleep diary and underwent actigraphy for 7 days. Insomnia (chronic sleep disturbance associated with impaired daytime functioning) was present in 27.3% of participants. Current tobacco users (odds ratio (OR), 2.13) and those with frequent sadness/anxiety (OR, 3.57) had higher odds, but oxygen use was associated with lower odds (OR, 0.35) of insomnia. Patients with insomnia had worse quality of life and a higher prevalence of daytime sleepiness. Actigraphy revealed shorter sleep duration and lower sleep efficiency, and a sleep diary revealed worse self-reported sleep quality in participants with insomnia. Insomnia disorder is highly prevalent in patients with COPD; current tobacco use and sadness/anxiety are associated with a higher prevalence, and oxygen use with a lower prevalence of insomnia; patients with insomnia have poorer quality of life and increased daytime sleepiness; and insomnia is associated with worse objective sleep quality.

The aim of this study was to determine whether and to what extent a disease-specific health status questionnaire (Saint George’s Respiratory Questionnaire, SGRQ correlates with generic health status questionnaires (EuroQol-5-Dimensions, EQ-5D; Assessment of Quality of Life instrument, AQoL; Medical Outcomes Study 36-Item Short-Form Health Survey, SF-36 at four different time points in patients with advanced COPD; and to determine the correlation between the changes in these questionnaires during one-year follow-up. Methods Demographic and clinical characteristics were assessed in 105 outpatients with advanced COPD at baseline. Disease-specific health status (SGRQ and generic health status (EQ-5D, AQoL, SF-36 were assessed at baseline, four, eight, and 12 months. Correlations were determined between SGRQ and EQ-5D, AQoL, and SF-36 scores and changes in these scores. Agreement in direction of change was assessed. Results Eighty-four patients (80% completed one-year follow-up and were included for analysis. SGRQ total score and EQ-5D index score, AQoL total score and SF-36 Physical Component Summary measure (SF-36 PCS score were moderately to strongly correlated. The correlation of the changes between the SGRQ total score and EQ-5D index score, AQoL total score, SF-36 PCS, and SF-36 Mental Component Summary measure (SF-36 MCS score were weak or absent. The direction of changes in SGRQ total scores agreed slightly with the direction of changes in EQ-5D index score, AQoL total score, and SF-36 PCS score. Conclusions At four, eight and 12 months after baseline, SGRQ total scores and EQ-5D index scores, AQoL total scores and SF-36 PCS scores were moderately to strongly correlated, while SGRQ total scores were weakly correlated with SF-36 MCS scores

    COPD is a chronic pathological condition of the respiratory system characterized by persistent and partially reversible airflow obstruction, to which variably contribute remodeling of bronchi (chronic bronchitis), bronchioles (small airway disease) and lung parenchyma (pulmonary emphysema). COPD can cause important systemic effects and be associated with complications and comorbidities. The diagnosis of COPD is based on the presence of respiratory symptoms and/or a history of exposure to risk factors, and the demonstration of airflow obstruction by spirometry. GARD of WHO has defined COPD "a preventable and treatable disease". The integration among general practitioner, chest physician as well as other specialists, whenever required, assures the best management of the COPD person, when specific targets to be achieved are well defined in a diagnostic and therapeutic route, previously designed and shared with appropriateness.
