    ABSTRACT: Background and objectiveWe tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD).Methods Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms.ResultsIndividuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P < 0.001), and more of them had a history of respiratory infections (6.8 vs 1.4%, P < 0.001) than individuals with COPD but without gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3–5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6–2.7, P = 0.63).Conclusions Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly.

    ABSTRACT: We performed an audit on all admissions with chronic obstructive pulmonary disease (COPD) in ex-acerbation to the Department of Emergency Medicine, Odense University Hospital (DEM) in the second half of 2012 to evaluate if an organisational change had altered visitation, treatment, initiation of non-invasive ventilation (NIV) and monitoring. We chose not to include the entire year to avoid data influenced by organisational start-up difficulties. The hypothesis was that NIV was initiated according to guidelines to the same extent as prior to the implementation of DEM.

    ABSTRACT: Background:Exacerbations of chronic obstructive pulmonary disease (COPD) requiring hospital admission have important clinical and societal implications. Objective:We sought to investigate the incidence, recurrence, risk factors, and mortality of COPD patients with exacerbations requiring hospital admission compared to those without hospital admission during 3-year follow-up in 2138 COPD patients from the ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints) observational cohort. Methods:Time to first event of hospital admission analysis using Kaplan-Meier curves and Cox proportional hazard regression adjusting for possible confounders. Results:670 (31%) patients reported a total of 1452 COPD exacerbations requiring hospital admission during the study period; 313 patients (15%) reported multiple (>1) events. A prior history of exacerbation of COPD requiring hospital admission was the factor associated with the highest risk of a new hospitalization for exacerbation (hazard ratio 2.71, 95% confidence interval: 2.24-3.29, P <.001). Other risk factors included more severe airflow limitation, poorer health status, older age, radiological evidence of emphysema, and higher white blood cell count. Having been hospitalized for exacerbation significantly increased the risk of mortality (P <.001). Conclusions:Exacerbations of COPD requiring hospital admission occur across all stages of airflow limitation and are a significant prognostic factor of reduced survival across all COPD stages. COPD patients at a high risk of hospitalization can be identified by their past history for similar events, and other factors, including the severity of airflow limitation, poor health status, age, presence of emphysema, and leukocytosis.

    ABSTRACT: BACKGROUND: We tested the hypothesis that statin use in individuals with COPD is associated with a reduced risk of exacerbations. METHODS: We identified 5794 individuals with COPD and a measurement of C reactive protein (CRP) in the Copenhagen General Population Study (2003-2008). During 3 years of follow-up we recorded exacerbations with hospital admissions or oral corticosteroid treatment. In a nested case-control design, matching on age, gender, smoking, COPD severity and comorbidity, we estimated the association between statin use and exacerbations. In addition, we examined the association between statin use and high CRP (>3 mg/L), and the association between high CRP and exacerbations during follow-up. RESULTS: Statin use was associated with reduced odds of exacerbations in crude analysis, OR=0.68 (95% CI 0.51 to 0.91, p=0.01), as well as in multivariable conditional logistic regression analysis, OR=0.67 (0.48 to 0.92, p=0.01). However, in the subgroup with the most severe COPD and without cardiovascular comorbidity, we observed a null association between statin use and exacerbations, OR=1.1 (0.5 to 2.1, p=0.83). Furthermore, statin use was associated with reduced odds of a high CRP, OR=0.69 (0.56 to 0.85, p<0.001), and a high CRP was associated with an increased risk of exacerbations, HR=1.62 (1.35 to 1.94, p<0.001). We estimated the percentage of excess risk of the association of statin use with exacerbations possibly mediated through a reduction of CRP to be 14% (4-51%). CONCLUSIONS: Statin use was associated with reduced odds of exacerbations in individuals with COPD from the general population, although this was not apparent in those with the most severe COPD without cardiovascular comorbidity. Statins may thus only associate with reduced risk of exacerbations in patients with COPD with coexisting cardiovascular disease.

    ABSTRACT: Background: The prevalence of obesity has increased during the last decades and varies from 10-20% in most European countries to approximately 32% in the United States. However, data on how obesity affects the presence of airflow limitation (AFL) defined as a reduced ratio between forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) are scarce. Methods: Data was derived from the third examination of the Copenhagen City Heart Study from 1991 until 1994 (n = 10,135). We examine the impact of different adiposity markers (weight, body mass index (BMI), waist circumference, waist-hip ratio, and abdominal height) on AFL. AFL was defined in four ways: FEV1/FVC ratio < 0.70, FEV1/FVC ratio < lower limit of normal (LLN), FEV1/FVC ratio <0.70 including at least one respiratory symptom, and FEV1/FVC ratio < LLN and FEV1% of predicted < LLN. Results: All adiposity markers were positively and significantly associated with FEV1/FVC independent of age, sex, height, smoking status, and cumulative tobacco consumption. Among all adiposity markers, BMI was the strongest predictor of FEV1/FVC. FEV1/FVC increased with 0.04 in men and 0.03 in women, as BMI increased with 10 units (kg · m-2). Consequently, diagnosis of AFL was significantly less likely in subjects with BMI ≥ 25 kg · m-2 with odds ratios 0.63 or less compared to subjects with BMI between 18.5–24.9 kg · m-2 when AFL was defined as FEV1/FVC < 0.70. Conclusion: High BMI reduces the probability of AFL. Ultimately, this may result in under-diagnosis and under-treatment of COPD among individuals with overweight and obesity.

    ABSTRACT: BackgroundCOPD patients have increased numbers of macrophages and neutrophils in the lungs. Interleukin-6 (IL-6) trans-signaling via its soluble receptor sIL-6R, governs the influx of innate immune cells to inflammatory foci through regulation of the chemokine CCL3. We hypothesized that there would be enhanced levels of IL-6, sIL-6R and CCL3 in COPD sputum.Methods59 COPD patients, 15 HNS and 15 S underwent sputum induction and processing with phosphate buffered saline to obtain supernatants for IL-6, sIL-6R and CCL3 analysis. Cytoslides were produced for differential cell counting and immunocytochemistry (COPD; n¿=¿3) to determine cell type surface expression of the CCL3 receptors CCR5 and CCR1.ResultsCOPD patients expressed higher levels (p¿<¿0.05) of sIL-6R and CCL3 compared to controls (sIL-6R medians pg/ml: COPD 166.4 vs S 101.1 vs HNS 96.4; CCL3 medians pg/ml: COPD 117.9 vs S 0 vs HNS 2.7). COPD sIL-6R levels were significantly correlated with sputum neutrophil (r¿=¿0.5, p¿<¿0.0001) and macrophage (r¿=¿0.3, p¿=¿0.01) counts. Immunocytochemical analysis revealed that CCR5 and CCR1 were exclusively expressed on airway macrophages.Conclusion Enhanced airway generation of sIL-6R may promote IL-6 trans-signaling in COPD. Associated upregulation of CCL3 may facilitate the recruitment of macrophages into the airways by ligation of CCR1 and CCR5.

    ABSTRACT: COPD is today the third leading cause of death worldwide and its prevalence has steadily increased. Prevalence in Europe seems to be levelling, and in western and northern Europe, recent data even indicate a decrease. Beyond tobacco, other major risk factors have been identified, while objective possibilities for prevention exist. New medicines and treatment strategies can slow down disease progression. COPD heterogeneity is huge and restricts treatment options, and epidemiology can contribute to identifying clinically relevant phenotypes of COPD.

    ABSTRACT: Clinical studies have suggested that inhaled corticosteroid (ICS) increases the frequency of pneumonia in patients with chronic obstructive pulmonary disease (COPD). This article summarizes the risk of pneumonia by reviewing the largest clinical studies addressing pneumonia as an adverse effect of ICS treatment. The collected data show that treatment of COPD patients with ICS increases the rate of pneumonia compared with b2-agonists or placebo. Physicians are recommended to follow guidelines and solely treat COPD patients with ICS if the patients are at high risk of exacerbations.

    ABSTRACT: Depression is highly prevalent among patients with Chronic Obstructive Pulmonary Disease (COPD). The relationship of depression with systemic inflammation in COPD remains unknown. The objective of this observational study was to compare depression scores at baseline and after 36 months follow-up between COPD patients with persistent systemic inflammation (PSI) and never inflamed patients (NI) in the ECLIPSE cohort.

    ABSTRACT: Little is known about changes in physical activity in subjects with chronic obstructive pulmonary disease (COPD) and its impact on mortality. Therefore, we aimed to study changes in physical activity in subjects with and without COPD and the impact of physical activity on mortality risk. Subjects from the Copenhagen City Heart Study with at least two consecutive examinations were selected. Each examination included a self-administered questionnaire and clinical examination. 1270 COPD subjects and 8734 subjects without COPD (forced expiratory volume in 1 s 67±18 and 91±15% predicted, respectively) were included. COPD subjects with moderate or high baseline physical activity who reported low physical activity level at follow-up had the highest hazard ratios of mortality (1.73 and 2.35, respectively; both p<0.001). In COPD subjects with low baseline physical activity, no differences were found in survival between unchanged or increased physical activity at follow-up. In addition, subjects without COPD with low physical activity at follow-up had the highest hazard ratio of mortality, irrespective of baseline physical activity level (p≤0.05). A decline to low physical activity at follow-up was associated with an increased mortality risk in subjects with and without COPD. These observational data suggest that it is important to assess and encourage physical activity in the earliest stages of COPD in order to maintain a physical activity level that is as high as possible, as this is associated with better prognosis.

    ABSTRACT: Hypoxemia is a major complication of Chronic Obstructive Pulmonary Disease (COPD) that correlates with disease prognosis. Identifying genetic variants associated with oxygenation may provide clues for deciphering the heterogeneity in prognosis among COPD patients. However, previous genetic studies have been restricted to investigating COPD candidate genes for association with hypoxemia. To report results from the first genome-wide association study (GWAS) of resting oxygen saturation in COPD cases, we performed a GWAS of pulse oximetry (SpO2) in two large, well-characterized COPD populations: COPDGene, including both the Non-Hispanic White and African American groups, and ECLIPSE. We identified several suggestive loci (P<1x10-5) associated with SpO2 in COPDGene in the Non-Hispanic White (N=2810) and ECLIPSE (N=1758) and two loci on chromosome 14 and 15 in the African American (N=820) from COPDGene achieving a level of genome-wide significance (P<5x10-8). The chromosome 14 SNP rs6576132, located in an intergenic region, was nominally replicated (P<0.05) in the Non-Hispanic White from COPDGene. The chromosome 15 SNPs were rare in subjects of European ancestry, so the results could not be replicated. The chromosome 15 region contains several genes including TICRR and KIF7 and is proximal to RHCG, Rh family C glyocoprotein gene. We have identified two loci associated with resting oxygen saturation in African Americans with COPD and several suggestive regions in COPD cases of European descent. Our study highlights the importance of investigating the genetics of complex traits in different racial groups.

    ABSTRACT: It has been suggested that identifying phenotypes in chronic obstructive pulmonary disease (COPD) might improve treatment outcome and the accuracy of prediction of prognosis. In observational studies vitamin D deficiency has been associated with decreased pulmonary function, presence of emphysema and osteoporosis, upper respiratory tract infections, and systemic inflammation. This could indicate a relationship between vitamin D status and COPD phenotypes. The aim of this study was to assess the association between vitamin D levels and COPD phenotypes. In addition, seasonality of vitamin D levels was examined. A total of 91 patients from a Danish subpopulation of the "Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points" cohort took part in a biomarker substudy. Vitamin D concentration was measured from blood samples taken at two visits, approximately 6 months apart. The participants were 40-75-year-old patients with COPD and had a smoking history of >10 pack-years. Fifty-six patients had 25-hydroxyvitamin D measured from blood samples from both visits. In the final model of the multivariate analyses, the factors that were associated with vitamin D deficiency at the first visit were age (OR: 0.89, p = 0.02) and summer season (OR: 3.3, p = 0.03). Factors associated with vitamin D level also at the first visit were age (B: 0.9, p = 0.02) and 6 min walking distance (B: 0.05, p = 0.01). Vitamin D was not associated with COPD phenotypes and season did not seem to be a determinant of vitamin D levels in patients with moderate to severe COPD.

    ABSTRACT: The study evaluated the efficacy of beclomethasone dipropionate/formoterol fumarate (BDP/FF) extrafine combination versus fluticasone propionate/salmeterol (FP/S) combination in COPD patients. The trial was a 12-week multicentre, randomised, double-blind, double dummy study; 419 patients with moderate/severe COPD were randomised to BDP/FF 200/12 mug or FP/S 500/50 mug twice daily. The primary objective was to demonstrate the equivalence between treatments in terms of Transition Dyspnoea Index (TDI) score and the superiority of BDP/FF in terms of change from pre-dose in the first 30 minutes in forced expiratory volume in the first second (FEV1). Secondary endpoints included lung function, symptom scores, symptom-free days and use of rescue medication, St. George's Respiratory Questionnaire, six minute walking test and COPD exacerbations. BDP/FF was equivalent to FP/S in terms of TDI score and superior in terms of FEV1 change from pre-dose (p < 0.001). There were no significant differences between treatments in secondary outcome measures, confirming overall comparability in terms of efficacy and tolerability. Moreover, a clinically relevant improvement (>4 units) in SGRQ was detected in the BDP/FF group only. BDP/FF extrafine combination provides COPD patients with an equivalent improvement of dyspnoea and a faster bronchodilation in comparison to FP/S.Trial registration: ClinicalTrials.gov: NCT01245569.

    ABSTRACT: Variation in Surfactant Protein D (SP-D) is associated with lung function in tobacco smoke-induced chronic respiratory disease. We hypothesized that the same association exists in the general population and could be used to identify individuals sensitive to smoke-induced lung damage. The association between serum SP-D (sSP-D) and expiratory lung function was assessed in a cross-sectional design in a Danish twin population (N=1,512, 18-72 years old). The adjusted heritability estimates for expiratory lung function, associations between SP-D gene (SFTPD) single-nucleotide polymorphisms or haplotypes, and expiratory lung function were assessed using twin study methodology and mixed-effects models. Significant inverse associations were evident between sSP-D and the forced expiratory volume in 1 second and forced vital capacity in the presence of current tobacco smoking but not in non-smokers. The two SFTPD single-nucleotide polymorphisms, rs1923536 and rs721917, and haplotypes including these single-nucleotide polymorphisms or rs2243539, were inversely associated with expiratory lung function in interaction with smoking. In conclusion, SP-D is phenotypically and genetically associated with lung function measures in interaction with tobacco smoking. The obtained data suggest sSP-D as a candidate biomarker in risk assessments for subclinical tobacco smoke-induced lung damage. The data and derived conclusion warrant confirmation in a longitudinal population following chronic obstructive pulmonary disease initiation and development.
