Filter by:This is an international Delphi study to consolidate expert consensus on the use of respiratory oscillometry in the management of adult patients with asthma or chronic obstructive pulmonary disease (COPD). The primary objective of the Delphi study is to aid the interpretation of respiratory oscillometry in clinical practice amongst adult patients with asthma or COPD. This will be achieved by obtaining expert consensus on: - Which parameters are used in clinical practice for impulse oscillometry (IOS) and for forced oscillation technique (FOT) devices. - What cut-offs can be used for each parameter to guide clinical practice in the management of adult patients with asthma and COPD. This study is based on the Delphi methodology. The Delphi study will comprise of four rounds, one brainstorming round, to formulate the consensus survey, and three rounds to attempt to obtain consensus. In each round a questionnaire comprising of statements and questions regarding respiratory oscillometry will be sent to participants in the Delphi study electronically using SurveyLet, an online survey platform. Participants will respond anonymously to the survey questions, indicating their level of agreement or disagreement with each statement or question. Participants will be given 4 weeks to complete each round of the Delphi study. Questions and statements will be repeated in subsequent rounds until the predefined level of consensus is met or the maximum number of rounds is achieved (limited to a maximum of 3 rounds). Aggregated results for each statement or question, including distribution of results and consensus status, will be provided to participants after each round to facilitate informed decisions in subsequent rounds.
It is unknown whether individuals with COPD exhibit abnormal alveolar-capillary breaching during exercise, and whether this contributes to exertional dyspnoea. The aim of this study is to investigate whether individuals with COPD exhibit an abnormal increase in alveolar-capillary breaching during exertion, as indicated by an increase alveolar-capillary permeability with a concomitantly exacerbated increase in lung tissue mass.
The goal of this study is to proliferate human lung stem cell in vitro in order to establish a lung organoid derived from patients with COPD. The main question it aims to answer are: - Can human lung stem cell proliferate in vitro. - Can a lung organoid derived from patients with COPD be established. Participants will be sampled during pulmonary bronchoscope for organoid establishment.
This study aims to analyze if patients with chronic obstructive lung disease who experience a decline of blood oxygen saturation during physical exercise have a disease course different from that of COPD patients who do not experience a decline in blood oxygen saturation during exercise. Patients will be followed for a total of 3 years.
The current "Global Initiative for Chronic Obstructive Lung Diseases" (GOLD) guideline emphasizes that pulmonary rehabilitation should be recommended to all chronic obstructive pulmonary disease (COPD) patients from Stage II onwards. Respiratory muscle training applied to individuals with COPD is an important part of pulmonary rehabilitation due to its benefits such as improving pulmonary function and respiratory muscle strength, reducing the severity of dyspnea, and increasing exercise capacity and quality of life. Although there is sufficient evidence in the literature about the benefits of IMT in individuals with COPD. There is little evidence showing the effects of EMT. Studies show that isolated IMT and EMT are effective in increasing respiratory muscle strength, endurance and exercise capacity. Results from a limited number of studies show that combined training of IMT and EMT is superior compared to isolated IMT or isolated EMT in improving exercise capacity and dyspnea. Incentive spirometers, with their different mechanical properties, are low-cost respiratory exercise devices that are widely used in the early postoperative period, lung diseases, long-term bed rest and in situations where it is necessary to maintain or increase the ventilation ability of the lung, but they do not apply any resistance to the respiratory muscles. In the pulmonary rehabilitation guidelines published by the American Thoracic Society (ATS) and the European Respiratory Society (ERS), the necessity of using devices that apply resistance to the respiratory muscles to strengthen the respiratory muscles is underlined. The personalized respiratory exercise device will be a device that has the clinical features of an incentive spirometer and respiratory muscle training devices (inspiratory and expiratory) and can be personalized according to the desired purpose. With the same device, patients will be able to both improve lung ventilation, such as an incentive spirometer, and strengthen their respiratory muscles.
Hypothesis Treatment with HFNC and OptiflowTM+Duet can significantly reduce PaCO2 and normalize pH in patients with COPD exacerbation and acute hypercapnic failure, compared to HFNC with OptiflowTM. Treatment with High flow and OptiflowTM+Duet in patients with COPD exacerbation and acute hypercapnic failure is well tolerated. Aims To investigate the effect of HFNC in combination with either OptiflowTM or OptiflowTM+Duet nasal cannula on PaCO2 levels and pH in patients with COPD exacerbation and acute hypercapnic failure and compare the results of treatment with the two different nasal cannulas. To describe adherence to treatment with high flow and either OptiflowTM or OptiflowTM+Duet nasal cannula. Methods Study design The study will be carried out as a prospective, multicenter, randomized controlled trial. - Patients COPD and acute hypercapnic who do not tolerate NIV-treatment will be treated with HFNC for respiratory support. Patients will be randomized to either OptiflowTM /OptiflowTM+Duet nasal cannulas ("Fisher & Paykel Healthcare", Auckland, New Zealand) - HFNC treatment with allocated nasal cannula, flow 40-60 (prescribed by the responsible clinician) will be initiated, titration of FiO2 till target SO2 is reached (as prescribed by the responsible clinician or by default 88-92%). Maximal flow and target saturation should be reached within 1.5 hours of initiation. - Arterial puncture (registering pH, PaO2, PaCO2, HCO3, SaO2 and Base Excess) will be drawn at baseline and repeated after two hours (±30 minutes and after flow and FiO2 have been stable for 30 minutes) and at termination of the HFNC. - Patients will remain in study till it is decided by the treating physician to terminate HFNC-treatment. Patients who are candidates for invasive ventilations will be excluded from the study if the arterial blood gasses further deteriorate after initiation of HFNC.
This is a registry-based, randomized, controlled clinical trial of the effect of added high-flow oxygen therapy (using the device Lumis HFT) during one year in people with long-term oxygen therapy (LTOT) for chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD).
The aim of this study is to investigate cervical region biomechanics, muscle performance and respiratory muscle strength in patients with Chronic Obstructive Pulmonary Disease (COPD) compared to healthy subjects.
Several studies have demonstrated the benefits of the LAMA (Long-Acting Muscarinic Antagonists) + LABA (Long-Acting Beta-Agonists) + IC (inhaled corticosteroids) combination in the treatment of chronic obstructive pulmonary disease (COPD). The use of the triple combination in patients with severe airflow obstruction and a history of flares has been associated with improved lung function, improved patient-reported endpoints and prevention of flares, when compared to LABA, LABA + LAMA and LABA + IC. Furthermore, when compared to dual therapies LABA + IC and LABA + LAMA, triple therapy has been able to reduce all-cause deaths among chronic obstructive pulmonary disease (COPD) patients. Previously published studies have demonstrated that the triple combination of Fluticasone 250 mcg/Formoterol 12 mcg/Glycopyrronium 12.5 mcg was able to improve lung function in chronic obstructive pulmonary disease (COPD) patients with a history of flares. There was also a significant improvement in the mMRC (modified-Medical Research Council) which began in the 2nd week of treatment and continued up to week 12. The association was considered safe and well tolerated, with only mild to moderate adverse events recorded in approximately 25% of the subjects treated in the study. Furthermore, bioavailability studies performed with the components of the combination proposed as experimental drug - Fluticasone/Formoterol/Glycopyrronium - indicated that there is no pharmacokinetic interaction between the 3 active ingredients when they were administered concomitantly to healthy individuals under fasting conditions.
Dyspnea, more commonly known as breathlessness, is a symptom found in the majority of patients with chronic obstructive pulmonary disease (COPD), with a major impact on quality of life and mortality. COPD is a chronic inflammatory disease of the bronchi, affecting 8% of the French population (more than 3 million people). By 2030, it will be the third leading cause of death worldwide. Effective management of dyspnea in these patients is a priority. In patients with severe COPD, physical exertion increases the workload of breathing, leading to dyspnea. At the same time, the respiratory muscles and fatty cells release cytokines, myokines and adipokines - a group of proteins involved in the inflammatory response. In addition, 15% of COPD patients suffer from sarcopenia (loss of muscle mass and strength) which increases respiratory effort and dyspnea. Our research project aims to study the effect of dyspnea relief in COPD patients on cytokine, myokine and adipokine levels, taking into account the presence of sarcopenia. Indeed, it is possible to alleviate the workload of the respiratory muscles during exercise by means of respiratory assistance. The ultimate goal is a better understanding of dyspnea mechanisms, to enable the development of cytokine-targeted therapies and improve quality of life and survival in these patients.
