Dynamic hyperinflation during the 6-min walk test in severely asthmatic subjects
2018
We tested the hypothesis that dynamic hyperinflation develops in severe asthmatic subjects during exercise. Changes in inspiratory capacity (IC) were measured during the 6-min walk test (6MWT) in severe asthmatic subjects compared with chronic obstructive pulmonary disease (COPD) subjects with a similar degree of bronchial obstruction. We assessed whether changes in IC were associated with changes in dyspnoea perception. 27 severe asthmatic subjects (10 males and 17 females) and 43 COPD subjects (35 males and eight females) were recruited. The two groups performed similarly in the 6MWT (p=0.90). At the end of the test, the Borg score increased significantly in both groups (mean difference: …
Alternative mechanisms for tiotropium
2009
Tiotropium is commonly used in the treatment of chronic obstructive pulmonary disease. Although largely considered to be a long-acting bronchodilator, its demonstrated efficacy in reducing the frequency of exacerbations and preliminary evidence from early studies indicating that it might slow the rate of decline in lung function suggested mechanisms of action in addition to simple bronchodilation. This hypothesis was examined in the recently published UPLIFT study and, although spirometric and other clinical benefits of tiotropium treatment extended to four years, the rate of decline in lung function did not appear to be reduced by the addition of tiotropium in this study. This article summ…
A simple noninvasive pressure–time index at the mouth to measure respiratory load during acute exacerbation of COPD A comparison with normal voluntee…
2003
We assessed the validity of the pressure-time index (PTI) measured at the mouth as a noninvasive and simplified alternative to conventional tension-time index for assessing respiratory load and inspiratory muscle force reserve. PTI was measured within 48 h of hospital admission and at 24 h before discharge in 37 consecutive patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) using the equation PTI = (P(awo)/MIP)(T(I)/T(T)) 100, where P(awo) is the mean airway pressure measured at the mouth, MIP the maximal inspiratory pressure, and T(I)/T(T) the inspiratory time (T(I)) to total cycle length (T(T)) ratio. Controls were 30 normal volunteers with similar anthropome…
Effectiveness and safety of concurrent beta-blockers and inhaled bronchodilators in COPD with cardiovascular comorbidities
2017
Chronic obstructive pulmonary disease (COPD) is the most common chronic respiratory disease and its prevalence is increasing worldwide, in both industrialised and developing countries. Its prevalence is ∼5% in the general population and it is the fourth leading cause of death worldwide. COPD is strongly associated with cardiovascular diseases; in fact, ∼64% of people suffering from COPD are treated for a concomitant cardiovascular disease and approximately one in three COPD patients die as a consequence of cardiovascular diseases.Inhaled bronchodilators might have adverse cardiovascular effects, including ischaemic events and arrhythmias, and beta-blockers might adversely influence the resp…
Circulating haemopoietic and endothelial progenitor cells are decreased in COPD
2006
Circulating CD34+ cells are haemopoietic progenitors that may play a role in tissue repair. No data are available on circulating progenitors in chronic obstructive pulmonary disease (COPD). Circulating CD34+ cells were studied in 18 patients with moderate-to-severe COPD (age: mean+/-sd 68+/-8 yrs; forced expiratory volume in one second: 48+/-12% predicted) and 12 controls, at rest and after endurance exercise. Plasma concentrations of haematopoietic growth factors (FMS-like tyrosine kinase 3 (Flt3) ligand, kit ligand), markers of hypoxia (vascular endothelial growth factor (VEGF)) and stimulators of angiogenesis (VEGF, hepatocyte growth factor (HGF)) and markers of systemic inflammation (tu…
P123 Inhaled corticosteroid plus long-acting β2-agonist therapy is overused in the treatment of patients with chronic obstructive pulmonary disease: …
2015
Rationale Inhaled corticosteroid (ICS) plus long-acting β2-agonist (LABA) therapy is indicated for different patient groups with chronic obstructive pulmonary disease (COPD) in the USA and Europe. In the previous version of the Global initiative for chronic Obstructive Lung Disease (GOLD) recommendations, the use of ICS plus LABA therapy was restricted to patients with severe and very severe lung-function impairment and frequent exacerbations, with overtreatment in milder patient populations well documented. The current GOLD document recommends the use of ICS plus LABA maintenance therapy for patients in categories C and D. Methods We present post hoc analyses from the two pivotal 1-year TO…
Chronic Renal Failure
2010
Background To the best of our knowledge, the association between COPD and chronic renal failure (CRF) has never been assessed. Lean mass is frequently reduced in COPD, and the glomerular filtration rate (GFR) might be depressed in spite of normal serum creatinine (concealed CRF). We investigated the prevalence and correlates of both concealed and overt CRF in elderly patients with COPD. Methods We evaluated 356 consecutive elderly outpatients with COPD enrolled in the Extrapulmonary Consequences of COPD in the Elderly Study and 290 age-matched outpatients free from COPD. The GFR was estimated using the Modification of Diet in Renal Disease Study Group equation. Patients were categorized as …
P296 Effect of tiotropium/olodaterol therapy on copd exacerbations in the tonado® studies
2016
Rationale The lung-function efficacy, symptomatic benefits and safety of combined tiotropium (T), a long-acting muscarinic antagonist, and olodaterol (O), a long-acting β 2 -agonist, for the treatment of COPD, was established in the year-long TONADO ® studies (NCT01431274; NCT01431287). It is unknown if these benefits of T/O translate into a reduction in COPD exacerbation rate. Methods Two replicate, randomised, double-blind, parallel-group trials assessed T/O 2.5/5 μg and T/O 5/5 μg compared to the monocomponents T 5 μg, T 2.5 μg and O 5 µg (all delivered via Respimat ® inhaler) in patients with moderate to very severe COPD. Primary end points included lung function (forced expiratory volu…
P254 Once-daily Tiotropium And Olodaterol Fixed-dose Combination Via The Respimat(R) Improves Outcomes Versus Mono-components In Copd In Two 1-year S…
2014
Introduction Tiotropium (T), a once-daily long-acting muscarinic antagonist, is a well-established first-line maintenance treatment in chronic obstructive pulmonary disease (COPD); olodaterol (O) is a once-daily long-acting β 2 -agonist that has recently gained approval in several countries. Two Phase III replicate pivotal studies assessed the efficacy and safety of fixed-dose combinations of T and O (T+O) delivered via Respimat ® Soft Mist™ inhaler in patients with GOLD 2–4 COPD. Methods Two 52-week, double-blind, parallel-group studies randomised 5162 patients to O 5 µg, T 2.5 µg, T 5 µg, T+O 2.5/5 µg or T+O 5/5 µg. Primary efficacy end points were trough forced expiratory volume in 1 sec…
P256 Safety Of Once-daily Tiotropium And Olodaterol Fixed-dose Combination Via The Respimat In Chronic Obstructive Pulmonary Disease In Two 1-year St…
2014
Introduction The fixed-dose combination (FDC) of tiotropium (T), a once-daily long-acting muscarinic antagonist, and olodaterol (O), a once-daily long-acting β 2 -agonist, is currently being evaluated in chronic obstructive pulmonary disease (COPD). Two 52-week, Phase III replicate pivotal studies were conducted to assess the efficacy and safety of FDCs of T and O (T+O) delivered via Respimat® Soft Mist™ inhaler in patients (pts) with GOLD Stage 2–4 COPD. Pooled safety data from the two studies are presented here. Methods These were double-blind, randomised, parallel-group studies with 5 arms: O 5 µg, T 2.5 µg, T 5 µg, T+O 2.5/5 µg, T+O 5/5 µg. Key inclusion criteria were: age ≥40 years, di…
