Safety of tiotropium/olodaterol in chronic obstructive pulmonary disease: pooled analysis of three large, 52-week, randomized clinical trials.
2018
Abstract Background An extensive clinical trial program supports the efficacy and safety of tiotropium/olodaterol in chronic obstructive pulmonary disease (COPD). We examined the safety of tiotropium/olodaterol compared with tiotropium in a large population of patients, focusing on cardiovascular and respiratory events. Methods Patients (n = 9942) who received once-daily tiotropium/olodaterol 5/5 μg or tiotropium 5 μg (via Respimat®) in TONADO 1 & 2 and DYNAGITO were included. The number of patients and exposure-adjusted rate of events are presented for adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, and cardiovascular and respiratory events. Findings Fewer patient…
Reduced apoptosis of CD8+ T-Lymphocytes in the airways of smokers with mild/moderate COPD
2011
SummaryChronic obstructive pulmonary disease (COPD) is characterised by chronic inflammation in airways and lung parenchyma. CD8+ T-lymphocytes, crucial effector and regulatory cells in inflammation, are increased in the central and peripheral airways in COPD. The aim of this study was to assess the role of apoptosis in the accumulation of CD8+ T-lymphocytes within the airway wall in COPD. We examined the submucosa of transverse sections of central and peripheral airways from post-operative tissues from non-smokers (n = 16), smokers with normal lung function (n = 16), smokers with mild/moderate COPD (n = 16), and smokers with severe/very severe COPD (n = 9). TUNEL and immunohistochemistry t…
Physical inactivity in patients with COPD, a controlled multi-center pilot-study
2010
Physical activity (PA) has been reported to be reduced in severe chronic obstructive pulmonary disease (COPD). Studies in moderate COPD are currently scarce. The aim of the present study was to investigate physical activity in daily life in patients with COPD (n=70) and controls (n=30).A multi-center controlled study was conducted. PA was assessed using a multisensor armband device (SenseWear, BodyMedia, Pittsburgh, PA) and is reported as the average number of steps per day, and the time spent in mild and moderate physical activity.Patients suffered from mild (n=9), moderate (n=28), severe (n=23) and very severe (n=10) COPD. The time spent in activities with mild (80 + or - 69 min vs 160 + …
Ageing and COPD affect different domains of nutritional status: the ECCE study
2010
Chronic obstructive pulmonary disease (COPD) and ageing may contribute to malnutrition. We aimed to explore whether COPD and ageing determine malnutrition in different manners. 460 stable COPD outpatients (376 males and 84 females) from the Extrapulmonary Consequences of COPD in the Elderly (ECCE) study database were investigated (age 75.0±5.9 yrs; forced expiratory volume in 1 s 54.7±18.3% predicted). Nutritional status was evaluated using the Mini Nutritional Assessment® (MNA) questionnaire. From the MNA, three scores exploring the domains of the nutritional status were calculated: body composition, energy intake and body functionality scores. Global Initiative for Chronic Obstructive Lun…
Relationship between clinical and radiological signs of bronchiectasis in COPD patients: Results from COSYCONET.
2020
Bronchiectasis (BE) might be frequently present in COPD but masked by COPD symptoms. We studied the relationship of clinical signs of bronchiectasis to the presence and extent of its radiological signs in patients of different COPD severity. Visit 4 data (GOLD grades 1-4) of the COSYCONET cohort was used. Chest CT scans were evaluated for bronchiectasis in 6 lobes using a 3-point scale (0: absence, 1: ≤50%, 2: >50% BE-involvement for each lobe). 1176 patients were included (61%male, age 67.3y), among them 38 (3.2%) with reported physicians' diagnosis of bronchiectasis and 76 (6.5%) with alpha1-antitrypsin deficiency (AA1D). CT scans were obtained in 429 patients. Within this group, any sign…
Importance of noninvasively measured respiratory muscle overload among the causes of hospital readmission of COPD patients.
2008
To evaluate the influence of respiratory muscle overload and right cardiac overload among the possible risk factors of hospital readmission in a 1-year follow-up of a cohort of patients with moderate-to-severe COPD.A total of 112 COPD patients who were admitted consecutively to the hospital for acute exacerbation. At hospital discharge, we evaluated the conventional clinical and functional determinations in addition to the pressure-time index (PTI), which is obtained using the equation PTI = (Pawo/Pimax) x (Ti/Ttot) x 100, where Pawo represents the mean airway pressure measured at the mouth during spontaneous breathing, Pimax is the maximal inspiratory pressure, Ti is the inspiratory time, …
New horizons in early stage COPD--improving knowledge, detection and treatment.
2011
SummaryEarly stage COPD carries a significant healthcare burden that is currently underrecognised, underdiagnosed and undertreated. Furthermore, patients at this stage can rapidly decline to advanced disease, especially if they continue to smoke. The natural history of the disease in early stages remains largely unknown, and emerging evidence indicates that we are able to reduce lung function decline and exacerbations, and improve quality of life, in early stage COPD, mainly through smoking cessation. But new evidence from randomised clinical trials also suggests an impact of pharmacotherapy on clinical outcomes in early disease. Guidelines need to be updated to reflect this greater underst…
Association between reduced bronchodilatory effect of deep inspiration and loss of alveolar attachments.
2005
Abstract Background We have previously shown that the bronchodilatory effect of deep inspiration is attenuated in individuals with COPD. This study was designed to investigate whether the impairment in this effect is associated with loss of alveolar attachments. Methods We measured deep inspiration (DI)-induced bronchodilation in 15 individuals with and without COPD (67 ± 2.2 yrs of age, mean ± SEM) undergoing lobar resection for peripheral pulmonary nodule. Prior to surgery, we measured TLCO and determined the bronchodilatory effect of deep inspiration after constricting the airways with methacholine. The number of destroyed alveolar attachments, as well as airway wall area and airway smoo…
Direct effect of cigarette smoke on human pulmonary artery tension.
2010
The effect of chronic cigarette smoke on pulmonary artery (PA) tension has been studied extensively; nevertheless, the direct effect of cigarette smoke is poorly understood. We investigated the direct effect of cigarette smoke extract (CSE) on PA tension in non-smokers, smokers, and COPD patients in vitro. PA samples from 35 patients who underwent lung resection were examined by measuring isometric tension in response to increasing serotonin concentrations. CSE dose dependently inhibited the response to serotonin in smokers and COPD patients, and to a lesser extent in non-smokers. CSE-induced relaxation was similarly inhibited by the nonspecific nitric oxide synthase (NOS) inhibitor l-NOARG…
Effects Of Whole Body Vibration In Patients With Chronic Obstructive Pulmonary Disease - A Randomized Controlled Trial
2012
Summary Introduction To date endurance and strength training are established and evidence-based exercise methods in patients with chronic obstructive pulmonary disease (COPD). There is an unmet need for further research in new and complementary exercise modalities. Additional whole body vibration training during pulmonary rehabilitation may be such a new approach that has not yet been investigated in patients with COPD. Methods Eighty-two patients (65 ± 9 yrs, FEV 1 pred. 38 ± 11%, female 51%) with COPD in GOLD stage III to IV assessed for a 3-week inpatient multidisciplinary rehabilitation program were on top randomly assigned to one of two intervention groups: (1) 3 × 3 min of bilateral d…
