Filter by:The goal of this clinical trial is to learn whether semaglutide, an FDA-approved treatment for diabetes and obesity, is feasible and tolerable in patients with advanced lung disease. The main question[s] it aims to answer are: 1. Are patients with advanced lung disease able to tolerate semaglutide therapy? 2. Are we able to titrate semaglutide therapy to a target weight? Participants will be asked to perform pulmonary function, physical function and body composition testing, as well as a blood draw before and after 12-weeks of semaglutide therapy. While on therapy, subjects will be surveyed regarding any adverse events or side effects.
Chronic Obstructive Pulmonary Disease (COPD) causes obstruction to airflow when breathing out. It is a leading cause of chronic lung disease, hospitalization and death. Smoking is the major cause of COPD but why some smokers develop COPD while others do not is poorly understood. A central feature of COPD is accumulation of inflammatory blood cells, macrophages and neutrophils, in the airway, leading to lung injury and airway damage. The small airways of many patients with COPD contain bacteria, which are absent in healthy smokers or non-smokers. These bacteria stimulate recruitment of neutrophils, macrophages and other inflammatory cells, further accelerating airway injury. The investigators and others have shown resident macrophages in the lung and inflammatory cells (neutrophils and macrophages) recruited from the blood, which normally clear bacteria, have reduced anti-bacterial capacity in COPD and that their altered function impairs the resolution of inflammation. The investigators now wish to test why these cells fail to clear bacteria focusing in particular on how they use molecules as food to generate energy, a process termed metabolism, since this is an important determinant of immune cell function. Comparison will be made between lung resident cells (obtained by performing bronchoscopy and washing a segment of lung to flush out immune cells) and those from the blood to determine if the alterations are specific to the lung. The investigators will identify alterations in responses to bacteria in relation to changes in metabolism . A major focus will be on how structures in the cell that normally are key for energy production (i.e. mitochondria) become dysfunctional and how this impacts responses to bacteria. The investigators will relate findings to the clinical features of COPD and to healthy non-smokers and smokers to separate smoking-related changes from COPD. The aim is to develop new approaches with which to treat and manage COPD.
This is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical study, which aims to evaluate the efficacy, safety, and PK characteristics of Ensifentrine 3 mg twice daily (BID) for 24 weeks treatment of moderate to severe COPD.
Subjects who completed either OBERON or TITANIA will be offered the opportunity to consent for this Multicentre, Double-blind, Randomised, Placebo controlled, Parallel Group, Phase 3, extension study to evaluate the safety and efficacy of Tozorakimab in adult participants with symptomatic COPD.
The main objective of this study is to compare two independent groups of patients requiring lung biopsy for undetermined interstitial lung disease (ILD) in terms of diagnostic confidence as determined by histologists.
The aim of this study is to determine the effect of the health coaching approach applied to patients with Chronic Obstructive Pulmonary Disease on the perceived social support of the patients. Research Hypotheses: H0: Health coaching approach has no effect on perceived social support in patients with COPD. H1: Health coaching approach has an effect on perceived social support in patients with COPD.
Patients with Chronic obstructive pulmonary disease (COPD) experience gradually deteriorating lung function, which may be complicated by acute exacerbations. N- acetylcysteine (NAC) is frequently used in patients with COPD as a mucolytic. Besides its mucolytic effects, high-dose NAC has additional benefits in patients with stable COPD, including improving lung function and reducing exacerbations. Studies on the dose-dependent effects of NAC in COPD patients showed a high dose of NAC was needed to achieve its antioxidant effects and clinical benefits in COPD patients, whereas a dose of 600 mg once daily was not able to increase glutathione levels. According to a study conducted in Hong Kong on patients with stable COPD, 1 year of treatment with high-dose NAC at 600 mg twice daily improved small airways function in terms of forced expiratory flow and forced oscillation technique, and also significantly reduced exacerbation frequency with a decreasing trend in admission rate. In a meta-analysis, patients treated with NAC had significantly and consistently fewer exacerbations of COPD. The role of NAC was examined in a Delphi consensus study involving 53 COPD experts from 12 countries. Respondents agreed that regular treatment with mucolytic agents could effectively decrease the frequency of exacerbations and the duration of mild-to-moderate exacerbations, while delaying the time to first exacerbation and increasing symptom-free time in COPD patients. The panel also approved the doses of NAC with favourable side effect profiles to be recommended for regular use in patients with a bronchitic phenotype. However, there have been conflicting results regarding the efficacy of NAC for treating acute exacerbation of COPD. NAC has not been included as an adjunct for the treatment of COPD exacerbation in international guidelines. As NAC is relatively low cost, readily available, and has a favourable side effect profile as a treatment for COPD exacerbation, it is important to properly assess the clinical benefits of NAC as an adjunct to standard medical treatments to hasten recovery. This study is a double-blind randomised controlled trial on NAC as an adjunctive treatment for acute COPD exacerbation. It will assess the role of NAC in the treatment of acute COPD exacerbation.
Although we know that these numbers are underestimated, Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease that affects between 8 and 12% of adults. According to a 2020 WHO report, it is the third most common cause of mortality in developed countries. This disease is punctuated by exacerbations associated with an 8% mortality of hospitalized patients, increased to 24% when the patient is admitted to intensive care unit. Early detection and treatment of these exacerbations appears to be essential to improve patient survival. End-tidal carbon dioxide (EtCO2) is used to assess a patient's respiratory and hemodynamic status. Indeed, EtCO2 is a non-invasive measure that could allow the estimation of arterial carbon dioxide (PaCO2) without performing blood gases, an arterial blood sampling, classically at the radial artery. This study aimed to find an EtCO2 value which at the time of the initial management, would be predictive of a severe COPD exacerbation, as well as PaCO2.
The aim of this study is to assess the effectiveness of a communication intervention about sexuality on quality of life and other outcomes like physical activity, exercise capacity and health status in people with chronic obstructive pulmonary disease (COPD).
The current practice of oxygenation and/or ventilation supports in patients undergoing Fiberoptic Bronchoscopy is very heterogeneous among studies published in the literature; in addition, clear outcomes advantages of one strategy over another currently lack. The goal of this observational study is to describe the current practice of oxygenation and/or ventilation supports in patients undergoing Fiberoptic Bronchoscopy (FOB), stratified by baseline respiratory condition, co-morbidities, type of procedure and hospital settings. Investigators will enroll all adult patients undergoing any fiberoptic bronchoscopy in any clinical settings (from outpatients to critically ill patients). No specific exclusion criteria are indicated for enrollment in this study. Investigators will record the following data: - Patient's baseline data. - Type of FOB procedure: toilet bronchoscopy (for secretions, blood, mucus plugs removal), broncho-aspirate (BAS), bronchoalveolar lavage (BAL), brushing for cytology, biopsy, endobronchial ultrasound (EBUS). The type and size of bronchoscope (with or without an internal/external camera) and the time of the procedure will be also recorded. - Type of supportive strategy: no support, Standard Oxygen Therapy, High Flow Nasal Cannula, Continuous Positive Airway Pressure and or non invasive ventilation trough mask or helmet, invasive mechanical ventilation. - Sedation - Intra-procedural vital parameters - Occurrence of adverse events: desaturation (i.e. SpO2< 90% for at least 10 seconds), severe desaturation (i.e. SpO2< 80%), need for procedure interruption, hypotensive (systolic blood pressure <90 mmHg) or hypertensive (systolic blood pressure >140 mmHg) events, new onset of cardiac arrhythmias (specify the rhythm) or myocardial ischemia or electrocardiographic ST-alterations, neurological events (i.e. severe sensorium depression, psychomotor agitation). - Post-procedural vital parameters (15 minutes after the procedure). - Clinical outcomes: need for support escalation, need for admission to ward (for outpatient) or ICU (for outpatients and ward-admitted patient).
