The goal of the study is to evaluate a Home-Based Disease Management program specifically developed for patients with Gold III/IV COPD. By improving disease knowledge, awareness of significant clinical deterioration and self-management skills for patients, this Home-Based COPD Management Program is expected to reduce the severity of exacerbations, the need for emergency hospitalisations, thus demonstrating the efficacy and the cost effectiveness of this intervention.
NCT01099410
The purpose of this study is to compare the ability of two types of white blood cells to eat dead host cells, and how this process affects their ability to protect the body from infection. The two cell types are monocytes, a cell in the bloodstream, and alveolar macrophages, a cell in the lung that is ultimately derived from monocytes
NCT02314338
Patients with COPD often have limitations to physical performance. There are several tests for evaluating physical performance, unfortunately many of them can be time consuming and require specialized equipment an substantial space. Short physical performance battery is a simple test that requires little resources and can be performed both at institutions and in the homes of patients. SPPB has high predictive abilities in identifying older adults at greater risk for mortality, nursing home admission, hospitalization, and incidence of disability. The investigators would like to evaluate possible changes in the SPPB score after a 4-week rehabilitation program. The investigators would also like to look at possible relationships between the SPPB and other physical performance measures, dyspnea, anxiety, depression, fatigue, and health related quality of life.
NCT02285400
Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease characterized by airflow limitation that is progressive and not fully reversible. Expiratory flow limitation (EFL) is the main mechanism leading to dynamic pulmonary hyperinflation (DPH) and intrinsic positive end-expiratory pressure (PEEPi). DPH and PEEPi lead to increased inspiratory muscle efforts and impaired central drive mechanical and ventilation coupling, which is an important mechanism of dyspnea. Appropriate setting of extrinsic PEEP (PEEPe) can decrease inspiratory efforts and work of breathing, improve patient-ventilator synchrony in severe COPD patients with PEEPi and treated with mechanical ventilation. Nevertheless, the effects of CPAP/PEEPe level on respiratory mechanics, especially on central drive mechanical and ventilation coupling, still need further investigations. In the present study, about 40 patients with COPD will be recruited as research subjects. And the investigators aim to observe the changes in respiratory mechanics, central drive mechanics, central drive mechanical and ventilation coupling at different levels of CPAP. Contrast analysis will be conducted to evaluate the effects of CPAP level on respiratory mechanics and central drive during DPH, which may provide a reasonable basis for the clinical application of CPAP to COPD patients and the exploration of a new reasonable CPAP setting method.
NCT02638194
The primary purpose of this study is to examine the health effects of mainstream and secondhand hookah (i.e. water pipe) smoke on pulmonary and cardiovascular functions as well as serum levels of inflammatory biomarkers. Investigators would like to demonstrate that inhalation of both mainstream and secondhand smoke generated by hookah produces adverse pulmonary and cardiovascular effects and alterations in serum levels of inflammatory biomarkers.
NCT02636465
The purpose of this pilot study is to determine whether obese adults,obese (BMI\>30 kg/m2) with obesity hypoventilation or obese COPD-patients do undergo oxygen desaturation under flight simulation and if the hypoxic altitude simulation test is as effective as the hypoxic chamber test.

The main objective is to investigate the effect of iloprost on exercise endurance time during constant work rate cardiopulmonary exercise testing. Other efficacy and safety endpoints will additionally be analyzed.
NCT01044290
The purpose of this study is to determine whether discussions of life story, forgiveness, and future goals improve quality of life for patients with serious illness.
NCT02246569
For patients with emphysema lung volume reduction (ELVR) could be an expedient approach for the reduction of distension of the lung. ELVR may be performed using RePneu® Coils. After the insertion of the coils distended lung sections shrink so that healthy parts can expand. In the present study investigators intend to examine, whether the insertion of the coils improves diaphragm function and force of the breathing muscles. Investigators hypothesize that reduction of lung volume eliminates or reduces flattening of the diaphragm and relieves breathing muscles, respectively respiratory pump, which aims to reduce dyspnea.
NCT02346604
People with mild chronic obstructive pulmonary disease (COPD) can have significant physiological abnormalities and breathing inefficiency which become more pronounced during the stress of exercise, leading to intolerable breathing discomfort (dyspnea). To better understand the mechanisms of respiratory symptoms and exercise limitation in mild COPD, we will examine detailed lung function tests and other important measurements during rest and exercise in people with mild COPD compared with healthy non-smokers. This will be the first study to uncover the fundamental causes of breathing inefficiency and the related shortness of breath during physical exertion in patients with mild COPD. We hope to demonstrate that one simple measurement during exercise \[the relation (ratio) between the total amount of air breathed (ventilation) and the amount of carbon dioxide breathed out\] gives meaningful information about the extent of damage to the small airways and blood vessels in mild COPD and the overall gas exchanging function of the lungs, without the need for an arterial blood sample. This is a case-controlled observational study not involving an intervention. Participants will complete 2 visits approximately 1 week apart, each conducted at the same time of day. Visit 1 will consiste of screening for iligibility, symptom and activity assessments, pulmonary function tests and an incremental cycle cardiopulmonary exercise test (CPET) for familiarization purposes. Visit 2 will include spirometry followed by an incremental cycle CPET with detailed measures of ventilatory, gas exchange, sensory-perceptual and arterial blood gas responses.
NCT02603627
This study will investigate the prevalence of chronic obstructive pulmonary disease (COPD) in patients who are newly diagnosed with lung cancer and compare it to the prevalence of COPD in controls recruited from a smoking cessation clinic.
NCT01893476
Background: Chronic Obstructive Pulmonary Disease (COPD) remains a major health problem, which is strongly related to smoking. Despite publication of guidelines on the prevention and treatment of COPD, not all COPD patients receive the best available healthcare. Investigators developed a tailored implementation strategy for improving primary care physicians' adherence to COPD management guidelines. The primary aim of the presented trial is to evaluate the effects of this strategy on physician's performance. The secondary aim is to examine the validity of the tailoring of implementation interventions. Primary Trial Hypothesis: To study if the rate of adherence to the COPD guideline over a 1 year will increase among participants assigned to the intervention group in comparison to those assigned to the control group? Methods/Design: A two-arm pragmatic cluster randomized trial is planned. A total of 540 patients with diagnosed COPD will be included from 18 general practices in Poland. A tailored implementation program will be offered to general practitioners. Participating physicians in the intervention practices (n=18) will receive training to provide brief anti-smoking counselling. An additional form containing COPD severity scale will be inserted into patient's medical records. The checklist with key information about the disease and its management while consulting a patient with COPD will be provided to practitioners. Investigators will provide practices with training inhaler devices for general practitioners (GPs) to teach patients in correct use of each device and to note this education/training in patient's medical records. The control practices will provide usual care. Discussion: The results of this trial will be directly applicable to primary care in Poland and add to the growing body of evidence on interventions to improve chronic illness care.
NCT02307162
The purpose of the study is to assess the safety of single doses and multiple doses of a new formulation of RPL554 in healthy subjects and subjects with chronic obstructive pulmonary disorder.
NCT01361451
There are 24,000 admissions each year to Intensive Care Units (ICU) in the United Kingdom due to pneumonia, asthma and a common condition called chronic obstructive pulmonary disease (COPD), with rates of death of 10%, 40% and 50%, respectively. These conditions account for 10% of all ICU admissions. It is therefore important to find out if it would be possible to detect deteriorations in patients with breathing problems early, in order to increase appropriately their level of care. Clinical early warning scores (EWS) are used in many hospitals to detect patients whose medical condition is getting worse, and who are likely to need admission to intensive care or high dependency care units. EWS are usually calculated from several measurements taken from the patient, such as blood pressure, temperature and heart rate. However, they are often inaccurate as they need to be calculated manually by nursing staff from a number of measurements taken from a variety of different devices. Furthermore, even when accurately calculated, it is not clear how helpful EWS are in predicting whether or not patients will deteriorate. Neural respiratory drive (NRD) is an objective indicator of breathlessness, and can be derived from the amount of electrical activity occurring in certain muscles used in breathing. The Myotrace system measures this electrical activity, as well as measurements such as rate of breathing and heart rate. It then analyses these measurements together to help identify patients at risk of deterioration. This study will use Myotrace to monitor patients with severe breathing difficulties due to an acute worsening of chronic obstructive pulmonary disease, for early identification of failure to respond to medical treatment. Patients will be recruited at St. Thomas' Hospital. This research is funded by the Guy's and St. Thomas' Charity.

Acute consumption of dietary nitrate (as beetroot juice) has been shown to increase exercise and decrease systemic blood pressure in multiple populations, including COPD. The chronic effect of dietary nitrate in obstructive sleep apnea syndrome (OSAS) has not been reported.
NCT01151579
The purpose of the study is to determine adverse events rates of nebulized albuterol versus levalbuterol among adult critically ill patients and determine if a differential exists in adverse events between the two drugs.
NCT01572948
The purpose of the study is to propose that roflumilast is associated with meaningful reductions in biomarkers of pulmonary inflammation and sputum neutrophilia, including confirmation of previously described results, and correlate these findings with improvement in pulmonary function, sputum scores, and quality of life in stable moderate to severe COPD. The investigators aim to demonstrate this regardless of concomitant medication use, including inhaled corticosteroids. Additionally, the investigators hope to provide a mechanistic pathway by which these effects occur.
