SPIROMICS I, SPIROMICS II, and SPIROMICS III are longitudinal observational studies of Chronic Obstructive Pulmonary Disease (COPD) cohort. SPIROMICS I had two primary aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and to provide new ways of testing whether a new treatment is working. SPIROMICS II had three primary aims: (1) To define the natural history of "smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition; (2) To determine the radiographic precursor lesion(s) for emphysema and identify the molecular phenotypes underlying airway disease and emphysema; (3) To advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response. SPIROMICS III has three primary aims: (1) To identify the main forms of smoking-related airway disease that are caused by pathological airway mucus, their biological underpinnings, and their physiological significance; (2) To identify longitudinal trajectories in established and novel CT measures of emphysema, test how they predict COPD progression, and define their underlying biology; (3) To identify environmental and social determinants of health that impact disease severity and progression and their influence on lung structure, biology, and health disparities in COPD.

NCT06891274
In the in vitro modeling phase, the investigators plan to use a realistic human upper respiratory tract model and an asymmetric ideal bronchial tree model. By combining 3D printing experiments with CFD simulations, the investigators will investigate the respiratory tract deposition rate and distribution of micro - moist particles in ultrasound rock salt aerosol inhalation therapy. This will be compared with a small - volume nebulizer to verify the effectiveness of ultrasound rock salt aerosol inhalation therapy and lay the foundation for further research on the application of this inhalation technique to other drug formulations. In the clinical phase, the investigators plan to have subjects inhale radioactive aerosols and use PET/CT imaging technology to assess the deposition rate of aerosol particles in the lungs. By quantitatively analyzing the images, the investigators will study their distribution characteristics in real human bodies to verify the accuracy of the in vitro models and the potential for clinical application.

NCT06022627
The aim of the study In this study, pranayama yoga practices are the sub-dimensions of respiratory parameters, symptom and disease affection level, psychosocial adjustment and psychosocial adjustment in individuals with COPD. It was planned in a randomized controlled manner to examine the effects of healthcare compliance, professional environment, family environment, sexual relations, extended family relationships, social environment and psychological pressure. Pranayama yoga practices are aimed to reduce the frequency of symptoms and the level of disease exposure in individuals with COPD. Pranayama yoga practices are aimed to increase psychosocial adjustment in individuals with COPD. Pranayama yoga practices aim to increase compliance with health care, occupational, social and family environment, sexual and extended family relationships, and psychological pressure, which are the sub-dimensions of psychosocial adjustment in individuals with COPD. It is observed that all the yoga practices performed have improved the pulmonary functions of individuals with COPD, decrease the severity of symptoms, relieve inflammation, and increase muscle strength and physical performance. It was concluded that because of yoga increases awareness in patients, patients significantly reduce their level of depression and anxiety and adapt to social life. Yoga improves patients' quality of life by alleviating symptoms and increasing self-awareness. pranayama yoga practices are safe, home-applied, effective, cost-effective, complementary to drug therapy and can be performed during pulmonary rehabilitation for individuals with COPD (1-2) . The results of this study are important in guiding caregivers and healthcare professionals during the holistic care of COPD individuals and in pulmonary rehabilitation.
NCT02742597
The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 4 other provinces: British Columbia (BC); Manitoba (MB); Nova Scotia (NS); and New Brunswick (NB). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.

This trial aims to evaluate the clinical control rate of sputum by Zhuli Capsule in the treatment of the Phlegm-heat Syndrome （Tan-re Zheng）in the patients with acute exacerbation of chronic obstructive pulmonary disease or chronic bronchitis.
NCT03653104
This project seeks to pilot-test the feasibility of using a melodica training program to teach pursed lip breathing for Veterans with chronic obstructive pulmonary disease (COPD) with moderate to severe dyspnea (shortness of breath). Dyspnea occurs commonly among COPD patients and can limit activities of daily living. Pursed lip breathing is a strategy that can improve dyspnea and exercise capacity among COPD patients. The melodica is a musical instrument that looks like a keyboard with a mouthpiece on the side. The melodica is played by exhaling through the mouthpiece while pressing the keys. The MELODY pilot project protocol has been grounded on concepts from occupational therapy; specifically, providing participants with a meaningful new activity that is enjoyable, that can be provided across a spectrum of skill levels, that can provide participants with a new sense of self, and that can improve health outcomes (i.e., dyspnea and exercise endurance).
NCT03657121
Chronic Obstructive Pulmonary Disease (COPD) is a common progressive lung disease which causes breathlessness and frequent exacerbations, with patients often requiring hospitalisation. Patients with severe COPD commonly become housebound and lose their independence. They have a higher symptom burden than those with incurable lung cancer, yet are less likely to receive specialist palliative care, or to have been engaged in advance care planning (where patients discuss and often document their wishes regarding their future care). Hospital admissions become increasingly common towards the end-of-life; therefore, hospitalisation is a good opportunity to identify patients at risk of poor outcome. Such patients may wish to consider alternatives to admission and avoid intrusive treatments. Unfortunately, predicting which patients are likely to die in the near future is challenging thus far. The first step required to improve provision of palliative care services, and ensure patients are given the opportunity to make truly informed decisions about their future care, is accurate identification of those most likely to benefit. Well-designed clinical (prognostic) tools outperform clinician judgement in most settings. The investigators will compare the accuracy of one year mortality prediction of several clinical tools in patients who survive a COPD exacerbation requiring admission. This will initially be performed using existing data collected during previous research (the 1,593 patient validation study for the PEARL score - Previous admissions, extended Medical Research Council Dyspnoea score, Age, Right and Left heart failure), then confirmed in at least 310 patients admitted uniquely and consecutively with an exacerbation of COPD. The latter group of patients will be invited to participate in a longitudinal follow-up study, assessing symptom burden, quality of life, and readmissions over one year.
NCT00147082
The aim of this study is to investigate the mechanisms whereby leukocytes are recruited to the lung in chronic obstructive pulmonary disease (COPD) and cause tissue destruction. The hypothesis is that in COPD more leukocytes enter the lung and it is these cells that are responsible for the degradation of lung tissue. We, the researchers at Imperial College London, will isolate leukocytes from the blood of patients with COPD, healthy smokers and normal subjects and measure the movement of the leukocytes to chemoattractants. We will examine further, which cell surface receptors are responsible for this trafficking of cells. Furthermore, the differentiation of these cells in vitro will be compared with cells from healthy smokers and normal subjects. Specifically, the expression of enzymes that are responsible for tissue destruction and the cell surface receptors on these cells will be investigated. The objective is to identify the mechanisms whereby leukocytes from COPD patients behave differently to cells from healthy smokers and normal subjects with a view to identify novel targets for drug therapy.
NCT00147069
The aim of this study is to examine the inflammatory mechanisms involved in the pathogenesis of inflammatory lung disease, in particular to compare the inflammatory profile seen in asthma and COPD. Evidence for inflammation in asthma and COPD is based on the finding of increased numbers of macrophages and neutrophils in the lungs and respiratory secretions of these patients. The inflammatory cells produce proteases, as well as, reactive oxidant species resulting in a protease/anti-protease imbalance which favours lung destruction. The aim is to examine the inflammatory mediators released by inflammatory cells (such as, macrophages and lymphocytes) in order to determine whether there are differences between non-smoking subjects, smoking subjects and patients with asthma or COPD. Monocytes are precursors of alveolar macrophages, and both monocytes and neutrophils are recruited to the lung from the blood via the action of specific chemoattractants. We have evidence that in inflammation there are higher levels of these chemoattractants. Therefore these cells might also demonstrate the same changes seen in alveolar macrophages from these patients. We also aim to assess the role of the macrophage precursor (monocyte) and neutrophils in the blood. We will also assess lymphocyte/monocyte interaction. We will do this as the lymphocyte may be involved in the initial recruitment of inflammatory cells. We will also assess the role of cytokines involved with monocyte/macrophage/neutrophil migration in induced sputum as well as the role of induced sputum in the migration of monocytes and neutrophils into the lung. Our aim is to link the initial changes in blood to the changes causing disease in the lungs. We aim to examine cellular responses in four groups of subjects, namely (i) non-smoking controls, (ii) smokers without clinical evidence of COPD or asthma, (iii) smokers with COPD (iv) asthmatic patients.
NCT00298389
Patients with chronic obstructive pulmonary disease (COPD) that have frequent chest infections are the patients most likely to become worse over time. Why these people are more susceptible to chest infections is not known. One reason might be that the white cells in their lungs called macrophages do not work properly. Normally, these cells remove all the debris inhaled into the lung. This can also include bacteria. In patients with COPD, these macrophages are not able to remove these particles. The research question addresses why this happens
