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 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...

Inhaled, long-acting anticholinergic medication (LAA), commonly used for moderate-to-severe chronic obstructive pulmonary disease (COPD), has been shown to decrease COPD hospitalizations, emergency department visits, and acute exacerbations but has also been associated with urinary tract infection (UTI) in a prior meta-analysis. The objective of this study was to verify if there was an association between LAA and UTI in older individuals with COPD. A population-based, real-world cohort study using health administrative data from Ontario, Canada was conducted...

In severe COPD, patients having survived acute hypercapnic respiratory failure (AHRF) treated with noninvasive ventilation (NIV) have a high mortality and risk of readmissions. The aim was to analyze the prognosis for patients with COPD having survived AHRF and to assess whether previous admissions with NIV predict new ones.We conducted a retrospective follow-up analysis of 201 patients two years after NIV treatment of AHRF. Comparison of time-to-event in patients previously treated with NIV versus patients with no previous NIV treatment...

The new A-B-C-D Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification of severity of chronic obstructive pulmonary disease (COPD) is based on combined symptoms and exacerbation risk assessment. The assumed equivalence between dyspnoea modified Medical Research Council (mMRC) grade ≥2 and COPD Assessment Test (CAT) score ≥ 10 to identify more symptoms has been questioned. Whether the exacerbation risk assessment criteria, old GOLD spirometry staging and frequency of exacerbations, are equivalent has not been examined...

It is unclear whether concurrent pneumonia and chronic obstructive pulmonary disease (COPD) have a higher mortality than either condition alone. Further, it is unknown how this interaction changes over time. We explored the effect of pneumonia and COPD on inpatient, 30-day and overall mortality. We used a Veterans Health Affairs database to compare patients who were hospitalized for a COPD exacerbation without pneumonia (AECOPD), patients hospitalized for pneumonia without COPD (PNA) and patients hospitalized for pneumonia who had a concurrent diagnosis of COPD (PCOPD)...

Ageing is defined as a progressive decline of homeostasis that occurs after the reproductive phase of life is complete, which is thought to arise because of impaired DNA repair following damage. This leads to an increased risk of disease or death. Ageing is one of the most important risk factors for most chronic diseases. Chronic obstructive pulmonary disease (COPD) represents an important component of the increasingly prevalent multiple chronic debilitating diseases that are a major cause of morbidity and mortality, particularly in the elderly...

Inhaled indacaterol/glycopyrronium fixed-dose combination (IND/GLY) is approved in over 80 countries, including the EU, Japan, Australia and Switzerland and the US. The LANTERN study evaluated the efficacy of IND/GLY compared with inhaled long-acting β2-agonist (LABA)/inhaled corticosteroid (ICS) or salmeterol/fluticasone (SFC) in patients with moderate-to-severe COPD with a history of ≤1 exacerbation in the previous year. Here we present the efficacy and safety of IND/GLY versus SFC in the Chinese cohort from the LANTERN study...

Chronic obstructive lung disease (COPD) primarily affects men; however, its epidemiology has been changing because more women have become smokers. Recently, investigators found that although women and men were exposed to the same amount of smoke fume, women tended to have more severe disease and higher mortality rate. They also complain of more dyspnoea and may experience more severe exacerbations than men. This led to the question of whether sex has an impact on COPD course and whether women have a higher susceptibility to smoke fumes than men...

Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) coexist in 0.5-1% of the general population. Both OSA and COPD are associated with increased sympathetic nervous activity, and patients affected by both disorders have higher risk for increased morbidity and mortality as compared with patients with COPD or OSA alone. We tested the hypothesis that patients with COPD and OSA (Overlap syndrome) have higher sympathetic and lower parasympathetic modulation of heart rate variability (HRV) in comparison with patients suffering from COPD or OSA alone...

The inspiratory pressure is often set by tolerance of chronic obstructive pulmonary disease (COPD) patient during noninvasive pressure support ventilation (PSV). However, physiological effects of this setting remain unclear. This study was undertaken to assess the physiological effect of highest tolerated assist level on COPD patient.  The baseline inspiratory pressure (PS) was titrated by tolerance in 15 severe COPD patients with hypercapnia during acute exacerbation. In addition to the baseline PS, an additional decrease by 25% (PS- = 75% PS) or increase by 25% (PS+ = 125% PS) of PS was applied to the patients...

This study aimed to describe trends in the incidence of hip fracture hospitalizations, use of surgical procedures, and hospital outcomes among elderly patients with and without chronic obstructive pulmonary disease (COPD) in Spain (2004-2013). We selected all patients with a discharge primary diagnosis of hip fracture using the Spanish national hospital discharge database. Discharges were grouped by COPD status. From 2004 to 2013, 432,760 discharges with hip fracture were identified (6.9% suffered COPD). Incidence among COPD men increased by 2...
