Filter by:Early after allogeneic hematopoietic stem-cell transplantation (allo-HSCT), reductions of absolute lung volume and diffusing capacity for carbon monoxide (DLCO) are frequently detected even in the absence of overt idiopathic pneumonia syndrome (IPS). It can be hypothesized that these changes might be due to an occult intersitial lung disease associated with infections, acute Graft-versus-Host Disease (aGvHD), myeloablative conditioning regimens or any combination of these. To test this hypothesis, we will simultaneously measure the lung diffusing capacity for nitric oxide (DLNO) and DLCO and estimate the changes of membrane diffusing capacity (DM) and pulmonary capillary volume (Vc) by the DLNO/DLCO ratio. As we hypothesize that GHVD should be intuitively absent amongst autologous HSCT (auto-HSCT) recipients, we will compare the changes in DLNO/DLCO ratio showed by the latter group with those of subjects undergoing allo-HSCT.
Several studies show an association between chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD). Besides risk factors such as smoking, both are associated with physical inactivity, advanced age and systemic inflammation The use of coronary computed tomography (CCT) with multiple detectors is a diagnostic method for coronary disease, describing the anatomy and severity of arterial obstruction. One way of estimating the cardiovascular risk is coronary calcium score (CCS). Due to the association between COPD and CAD, it is likely that many patients with IHD diagnosed by CT have reduced lung function. The aim of this observational study is to establish the correlation between the CCS and lung function. It will also correlate the presence of irreversible airway obstruction with significant coronary lesions. Patients over 40 years referred to CCT who agree to participate in the study will perform a spirometry with bronchodilator and collect a blood sample to measure serum markers of inflammation and cardiovascular risk (glycemia, lipid profile, C reactive protein (CRP), tumor necrosis factor-alpha (TNF-Alpha) and fibrinogen). The data will be compared in the general population and in subgroups: smokers, former smokers and nonsmokers. One year after the CCT patients will be contacted by the investigators and accessed for emergency room visits, hospital admissions and fatal or nonfatal coronary or respiratory events. The investigators hypothesis is that reduced lung function is independently associated with elevated CCS and is, also a risk factor for increased hospital admission and coronary events. The concomitant assessment of lung function and CCS can contribute knowledge about the epidemiological association between pulmonary disease and CAD. This can also add to evidence for the use of spirometry as a marker of cardiovascular risk.
This is a placebo-controlled, double-blind, parallel, randomized, two-part, dose-confirming clinical study characterizing the pharmacodynamic effects of pulsed iNO using the combination product, inhaled nitric oxide/INOpulse DS-C vs. placebo in subjects with World Health Organization (WHO) Group 3 pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD) on Long Term Oxygen Therapy (LTOT).
This study compared the correct use of and patient preference for two drug delivery systems (inhalers) in patients with COPD
Patients with chronic obstructive pulmonary disease (COPD) experience breathing difficulties because the airways deep in their lungs become narrowed. COPD patients use inhaler drugs to provide relief from breathlessness. However, current inhalers are inefficient as they deliver a 'coarse-mist' of drug-droplets that do not reach the deep airways. In our study, we will use an inhaler of 'fine-mist' drug-droplets, tagged with a radioactive tracer to track them. We will take images of the lungs to see if the fine-mist droplets reach the deep airways, and assess if this improves the breathing capacity in our patients. Our research may allow the development of new, more efficient inhalers to improve treatment for patients with COPD.
Patients with chronic lung diseases such as Chronic Obstructive Pulmonary Disease (COPD), who perform regular physical activity, have improved health and wellbeing compared with those who do little exercise. The purpose of the study is to evaluate whether the use of a simple pedometer (step counter) to set targets for daily physical activity can encourage COPD patients referred for an 8-week pulmonary exercise based programme (PR) to be more active. The investigators also want to know whether the use of pedometers during PR can improve adherence, self-management and outcome in COPD.
Targeted Lung Denervation (TLD) Therapy will be a safe method to ablate the airway nerve trunks that travel parallel to and outside of the main bronchi and into the lungs to achieve targeted lung denervation and potentially improve breathing and quality of life for patients suffering from COPD. Use of the IPS System will be technically feasible in accessing the target treatment location and delivering RF energy to the target treatment location.
The purpose of this study is to evaluate the lung function response to UMEC/VI, UMEC, and VI in individual patients using a cross-over design. This is a multicenter, randomized, double-blind, 3-way crossover study. Eligible subjects will be randomized to a sequence of UMEC 62.5mcg, VI 25mcg, and UMEC/VI 62.5/25mcg. All subjects will receive each treatment once-daily for 14 days, and each treatment will be separated by a 10-14 day washout period. There will be a 5-7 day run-in period prior to randomization.
The aim of this study was to assess the effectiveness for small airway inflammation of 4 weeks lysozyme administration in Chronic Obstructive Pulmonary Disease (COPD) and/or asthma.
Pulmonary rehabilitation has been established as an evidence-based and recommended therapy in patients with chronic obstructive pulmonary disease (COPD). The aim of our study is to show a potential change in muscle fibre composition and in the amount of capillaries in quadriceps muscle from pre tob post 3-week rehabilitation. Pulmonary rehabilitation includes standardised exercise training, e.g. cycling and strength training for major muscle groups.
