Chronic and progressive dyspnea is the most characteristic symptom of chronic obstructive pulmonary disease. There are studies in the literature showing that electromyography activations of respiratory muscles increase in individuals with chronic obstructive pulmonary disease and that the severity of the perceived shortness of breath is associated with muscle activation. However, no study has been found comparing respiratory muscle activations during pursed lip breathing and normal breathing in the dyspnea reduction positions and supine position used in the treatment and management of chronic obstructive pulmonary disease. The aim of this study is to evaluate the effects of different dyspnea reduction positions on respiratory muscle activations separately, to compare respiratory muscle activation during normal breathing, respiratory control and pursed lip breathing during these different positions, and to classify muscle activations according to the severity of chronic obstructive pulmonary disease.
This study aims to use novel proton-based MRI techniques to assess lung function and structure in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and alpha-1-anti-trypsin deficiency (A1ATD). These novel MRI measures will be compared to matched contemporary clinical diagnostic tools, namely pulmonary function tests (PFTs) and computed tomography (CT) scans. MRI has the advantages of avoiding ionising radiation exposure (unlike CT scans) and can also provide regional measures of lung function (unlike PFTs which provide global measures of function). In addition, these MRI techniques do not require the use of any inhaled or injected contrast agents. Some patients enrolled in this study will be undergoing a lung volume reduction (LVR) procedure as part of their normal clinical care. LVR is an intervention for patients with severe lung disease and hyperinflation. It is a palliative therapy that helps to reduce lung hyperinflation through insertion of small valves in the airway or surgical removal of parts of the lung. This can lead to improvements in symptoms such as breathlessness and improve exercise tolerance due to better functioning of the lung. In this study, we will explore how lung MRI measures can be used to assess patients before and after an LVR intervention. This study will take place at the University of Nottingham in collaboration with Nottingham University Hospitals NHS Trust. The study will last for 3 years and participants will be asked to attend a screening visit (lasting up to 1 hour) and either one or two study visits (each lasting up to 3 hours).
Chronic respiratory diseases such as obstructive sleep apnea syndrome (OSA) and chronic obstructive pulmonary disease (COPD) constitute a major public health problem, due to their high prevalence, but especially because of their cardiovascular and metabolic morbidity and mortality and the associated costs for the health system. The organization of long-term management of these diseases is now part of the e-health process, digital health with the use of massive "big data" generated by care and follow-up. Therapeutic patient education and the integration of connected objects will allow personalized therapeutic education support with interventions by local medical staff adapted to the needs of the patients. This will also allow to objectify the effect of treatments such as continuous positive airway pressure (CPAP) for OSA or non-invasive ventilation (NIV) and/or oxygen therapy for COPD, not only on the prevention of respiratory decompensation but also on cardiovascular and metabolic risk factors which are major elements of the prognosis. This project will therefore make it possible to demonstrate the feasibility and to deploy a multi-actor care pathway in the territory. The investigators propose a prospective clinical study, conducted at the Verdun Hospital, with the main objective of studying the evolution of the quality of life of patients with a chronic respiratory pathology, during an integrated management at home for 6 months. The secondary objectives: - To study the evolution of the following parameters, before treatment (at inclusion) and after 6 months of integrated management: 1. Treatment compliance (CPAP or NIV/oxygen therapy) 2. Physical activity 3. Weight 4. Mean arterial pressure 5. Oxygen saturation, heart rate and respiratory rate for COPD patients 6. Severity of COPD for the patients concerned 7. Daytime sleepiness 8. Fatigue 9. Patient acceptability of the use of connected objects - To analyze the trajectories of the measures collected throughout the integrated management to identify specific profiles. - To analyze the daily data of the different connected objects and treatments with regard to the patients' profiles (according to age, gender, comorbidities, OSA or COPD group).
To study the predictors contribute to the progression of COPD by follow-up of patients with early COPD and analyze their changes in bioactive molecular, exhaled gas, CT image, lung function, patient's symptoms and life quality.
Chronic obstructive pulmonary disease (COPD) is presently the third leading cause of death worldwide and is characterized by irreversible airflow limitation diagnosed by spirometry. COPD is currently considered as a systemic disease with predominantly respiratory involvement, associated with numerous comorbidities. Among these, muscle wasting, present in about one third of patients, is associated with a higher mortality (up to 10-fold, irrespective of the severity of the obstruction). Muscle wasting is classically characterized by a decrease in muscle strength and volume (sarcopenia), which can be defined by a decrease in the muscle mass measured by dual X-ray absorptiometry: Appendicular Skeletal Muscle Mass or ASM / height < 7.0 kg/m2 in men and 5.5 kg/m2 in women. However, sarcopenia is largely underestimated in current clinical practice. Moreover, there is no specific treatment: only exercise training as part of respiratory rehabilitation has shown some efficiency. The underlying pathophysiological mechanisms are indeed poorly characterized. Fibrocytes, cells derived from blood monocytes and able to migrate to different organs in order to play pro-fibrotic or pro-inflammatory roles, play a key role in bronchial obstruction. They are recruited in the blood of COPD patients during an acute exacerbation according to a CXCL12/CXCR4 chemotactic axis. Their role in COPD sarcopenia is currently unknown, but recent data show that they are involved in a mouse model of muscular dystrophy. The hypothesis is that fibrocytes are involved in COPD sarcopenia.
Lung emphysema is often associated with chronic obstructive pulmonary disease (COPD) and without any cure. Dyspnea is the main, debilitating symptom and is relieved by inhaled bronchodilators and rehabilitation. However, a substantial number of patients continue to suffer from dyspnea and among these, many patients have severely hyperinflated lungs due to predominant emphysema. For selected patients, lung transplantation or lung volume reduction by surgical removal (LVRS) of the most emphysematous parts of the lung can improve symptoms and survival. However, LVRS is related to complications and not all patients are suitable for surgery. An alternative to LVRS is bronchial lung volume reduction with endobronchial valves (EBV). One-way valves are inserted in the bronchial system using a bronchoscope and it has emerged as a valid treatment option with similar effects as LVRS with reduction of hyperinflation and increasing pulmonary function, quality of life, and exercise capacity. The normal lung is colonized with several types of bacteria, and together this is called the microbiome. Some bacteria are potentially beneficial, while others are potentially harmful. After the insertion EBV, some patients develop chronic infections. The hypothesis is that the microbiome can affect the risk of this chronic infection, and therefore the objective of this study is to access the microbiome during the insertion of the EBV, and afterwards observe which patients develop chronic infection and if these patients are harbouring specific types of bacteria.
This is a pilot study to demonstrate early validation of objective home-monitoring of Chronic obstructive pulmonary disease (COPD) patients by combining accurate and relevant patient data of medication and lung function (lung impedance) through patient-facing devices.
The purpose of this randomized, placebo-controlled double-blind trial is to evaluate the effect of acetazolamide on right heart function at rest in lowlanders with chronic obstructive pulmonary disease (COPD) traveling to high altitude (HA) and developing early signs of altitude-illness.
The purpose of this study was to evaluate the clinical efficacy and safety of supine daoyin in the treatment of AECOPD.
