The inclusion of an asthma/chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) population in the 2015 Global Initiative for Chronic Obstructive Lung Disease strategic documents has raised questions about the profile of these patients in clinical practice, as they are mostly excluded from asthma and COPD clinical trials. We estimated the disease burden, co-morbidities, and respiratory treatments of patients with asthma/COPD overlap, utilizing the Truven MarketScan commercial and Medicare databases...

The purpose of this study was to determine whether expression of connective tissue growth factor (CTGF) protein in chronic obstructive pulmonary disease (COPD) is consistent in humans and animal models of COPD and to investigate the role of this protein in lung epithelial cells. CTGF in lung epithelial cells of ex-smokers with COPD was compared with ex-smokers without COPD by immunofluorescence. A total of twenty C57Bl/6 mice and sixteen non-human primates (NHPs) were exposed to cigarette smoke (CS) for 4 weeks...

A comprehensive diagnostic assessment is needed to improve understanding of the health status of patients with chronic obstructive pulmonary disease (COPD) or asthma. Therefore, this study investigated which components and subsequent instruments should be part of a holistic assessment in secondary care. We also explored which data need to be exchanged for an adequate transfer of patients between primary and secondary care, and vice versa. A cross-sectional Web-based survey was conducted among Dutch healthcare professionals using a Delphi-like procedure; these included professionals working in primary or secondary care, medical advisors of health insurance companies and patients' representatives...

The use of oral and inhaled corticosteroids is associated with increases in the risk of infection, especially pneumonia. The risk of sepsis with corticosteroid treatment in patients with chronic obstructive pulmonary disease (COPD) has been little studied, however. We assessed whether the use of inhaled and oral corticosteroids in COPD is associated with an increase in the risk of sepsis. We carried out a retrospective cohort study using the administrative health databases of the province of Quebec, Canada, over the period 1990-2007...

There is growing evidence that emphysema on thoracic computed tomography (CT) is associated with poor exercise tolerance in COPD patients with only mild-to-moderate airflow obstruction. We hypothesized that an excessive ventilatory response to exercise (ventilatory inefficiency) would underlie these abnormalities. In a prospective study, 19 patients (FEV1 = 82 ± 13%, 12 Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 1) and 26 controls underwent an incremental exercise test. Ventilatory inefficiency was assessed by the ventilation ([Formula: see text]E)/CO2 output ([Formula: see text]CO2) nadir...

Guideline adherence rates for the treatment of chronic obstructive pulmonary disease (COPD) exacerbation are low. The aim of this study is to perform an importance-performance analysis as an approach for prioritisation of interventions by linking guidelines adherence rates to expert consensus rates for the in-hospital management of COPD exacerbation. We illustrate the relevance of such approach by describing variation in guideline adherence across indicators and hospitals. A secondary data analysis of patients with an acute COPD exacerbation admitted to Belgian, Italian and Portuguese hospitals was performed...

Pulmonary rehabilitation (PR) is established as an effective intervention in optimising function and quality of life in patients with chronic obstructive pulmonary disease (COPD). However, there are very limited data on the effectiveness of PR in older patients with COPD. We reviewed all patients attending an 8-week outpatient programme. Patients were divided into two groups; Group A (n = 202), below 70 years, and Group B (n = 122), above 70 years of age. Outcomes in both patient subgroups were compared using FEV(1), Incremental Shuttle Walk Test (ISWT), Endurance Shuttle Walk Test (ESWT), Grip Strength, St...

Symptoms, clinical course, functional and biological data during an exacerbation of chronic obstructive pulmonary disease (EXCOPD) have been investigated, but data on physiological changes of respiratory mechanics during a severe exacerbation with respiratory acidosis requiring noninvasive mechanical ventilation (NIMV) are scant. The aim of this study was to evaluate changes of respiratory mechanics in COPD patients comparing data observed during EXCOPD with those observed during stable state in the recovery phase...

Asthma and chronic obstructive pulmonary disease (COPD) are heterogeneous diseases with different inflammatory phenotypes. Various inflammatory mediators play a role in these diseases. The aim of this study was to analyze the neutrophilic and eosinophilic airway and systemic inflammation as the phenotypic characterization of patients with asthma and COPD. Twenty-four patients with asthma and 33 patients with COPD were enrolled in the study. All the patients were in mild-to-moderate stage of disease, and none of them were treated with inhaled corticosteroids...

The aim of this study was to identify a multivariate model to predict poor outcomes after admission for exacerbation of chronic obstructive pulmonary disease (COPD).  We performed a multicenter, observational, prospective study. Patients admitted to hospital for COPD were followed up for 3 months. Relevant clinical variables at admission were selected. For each variable, the best cut-offs for the risk of poor outcome were identified using receiver operating characteristic (ROC) curves. Finally, a stepwise logistic regression model was performed...

In patients with stable COPD, proadrenomedullin (MR-proADM) has been shown to be a good predictor for mortality. This study aims to provide an external validation of earlier observed cut-off values used by Zuur-Telgen et al. and Stolz.et al. in COPD patients in stable state and at hospitalization for an acute exacerbation of COPD (AECOPD). From the COMIC cohort study we included 545 COPD patients with a blood sample obtained in stable state (n = 490) and/or at hospitalization for an AECOPD (n = 101). Time to death was compared between patients with MR-proADM cut-off scores 0...

There is little long-term follow-up data concerning the association between past pulmonary tuberculosis (TB), airway obstruction and mortality. We aimed to analyse a national health examination survey data from 6701 adult Finns undergoing spirometry between 1978 and 1980 (follow-up through 2013). We identified TB either through a disease history or by a TB-indicative scar on a chest x-ray. We specified obstruction using the lower limit of normal (LLN) and classified severity using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages 1-4...

Chronic obstructive pulmonary disease (COPD) is characterised by progressive and irreversible airflow limitation associated with chronic inflammation involving cytokines and metalloproteinases (MMPs). MMP-8, MMP-9 and neutrophil elastase (NE) are known to be implicated in COPD but the factors influencing activation and suppression remain unclear. This study aimed to compare MMP-8, MMP-9 and NE in the peripheral blood of COPD patients and controls and to likewise assess exhaled breath condensate (EBC) for these MMPs...

The transition dyspnea index (TDI) is among the most widely used instruments in chronic obstructive pulmonary disease (COPD) patients to measure changes in dyspnea over time. In its original version it is used as guideline for a structured interview to assess the impact of daily activities on dyspnea in the three subdomains: functional impairment, magnitude of task, and magnitude of effort. However, the TDI is sometimes used as a self-administered paper-and-pencil questionnaire. The validity of this questionnaire format has not been tested, which was the aim of the present study...

Alpha1-antitrypsin deficiency (AATD) is a genetic disorder characterized by reduced serum levels of alpha1-antitrypsin (AAT) and increased risk for developing both early-onset lung emphysema and chronic liver disease. Laboratory diagnosis of AATD is not just a matter of degree, although the AAT serum level is the most important determinant for risk of lung damage. While being a single-gene disease, the clinical phenotype of AATD is heterogeneous. The current standard of care for patients affected by AATD-associated pulmonary emphysema is replacement therapy with weekly i...

Chronic obstructive pulmonary disease (COPD) patients experiencing several episodes of acute clinical derangement suffer from increased morbidity, mortality, and accelerated decline in lung function. Nevertheless, the relationship between co-morbidity profile and exacerbation rates in the frequent exacerbator phenotype is poorly characterized, and evidence-based management guidelines are lacking. We sought to evaluate the co-morbidity profile and treatment patterns of "frequent exacerbators" with severe or very severe airflow limitation...

This retrospective cohort study aimed to assess treatment patterns over 24 months amongst patients with chronic obstructive pulmonary disease (COPD), initiating a new COPD maintenance treatment, and to understand clinical indicators of treatment change. Patients included in the study initiated a long-acting β2-agonist (LABA), a long-acting muscarinic antagonist (LAMA), or a combination of LABA and an inhaled corticosteroid (ICS/LABA) between January 1, 2009, and November 30, 2013, as recorded in the United Kingdom Clinical Practice Research Datalink (UK CPRD)...

Many individuals with Alpha-1 Antitrypsin Deficiency (AATD) are unaware of their diagnosis. In the absence of an AATD diagnosis, irreversible damage continues, and incorrect care is provided. Research demonstrates low levels of knowledge about AATD among health care providers. To address this ongoing issue, a short educational video was developed for health care providers with the goal of increasing knowledge and testing for AATD. A five-question test on the video material was developed. Invitations to participate in the study were sent via email to providers at both public teaching hospitals and private practices across the country...

We developed a questionnaire to detect cases of chronic obstructive pulmonary disease (COPD) and compared its reliability with other strategies. In order to develop the new questionnaire (COPD screening questionnaire from Terrassa [EGARPOC]) we used data from an epidemiological study on the prevalence of COPD in smokers and calculated the odds ratio for each variable showing significance for the diagnosis of COPD on regression analysis. For comparison among questionnaires and the portable spirometer COPD-6, a cross-sectional multicenter study was performed...
