Filter by:People living with chronic obstructive pulmonary disease (COPD) may experience worsening of symptoms such as shortness of breath, cough and wheezing in addition to changes that may be expected for having COPD. The worsening of symptoms is called exacerbations or flare-ups and can be debilitating and frightening, requiring additional treatment, often with azithromycin. This is an antibiotic medicine that also has anti-inflammatory properties. It is prescribed as long-term prevention to reduce the risk of flare-ups. Some people may be affected by side effects from azithromycin. Antibiotic resistance is another concern, especially when using azithromycin for prevention rather than to treat active infection. It is currently unclear as to whether people should be advised to stop taking azithromycin once COPD has stabilised, or to stop it over the summer when fewer flare-ups happen. It is also not known if azithromycin is more effective in some people or more likely to cause side effects in others. Given these uncertainties, it is challenging to know how best to use azithromycin in managing COPD. Azithromycin is a valuable antibiotic, and should be prescribed where it has benefit but avoid unnecessary side effects and reduce the chances of bacteria becoming resistant to it. The purpose of this trial is to be able to gain results to answer these questions, and to establish the effects of stopping azithromycin in people whose COPD has stabilised, who have been taking it for at least 3 months. This trial will compare continuing azithromycin with stopping it completely, or stopping over the summer only, continuing over the winter. The investigators will compare the effects of these three treatments in the trial on flare-ups, symptoms and quality of life, and find out what factors may affect how individual participants respond to them.
Background: In 2019, a novel coronavirus (SARS-COV2) was detected in Wuhan, China as a cause of acute respiratory distress syndrome (COVID-19). Other previous coronaviruses (SARS and MERS) have caused respiratory sequelae (pulmonary fibrosis) demonstrable by tomography and lung function tests. These alterations have begun to be detected in patients who have survived COVID-19. Hypotheses: SARS-COV2 infection accelerates the deterioration of lung function in patients with Chronic Obstructive Pulmonary Disease (COPD). Objectives: To analyze the evolution of lung function in COPD patients diagnosed with COVID-19, while comparing it with COPD patients without COVID-19 disease. Methodology: Cohort study. The COPD-COVID-19 cohort will consist of the COPD population with and without COVID-19. Previous pulmonary function data will be collected and 2 prospective visits (baseline and follow-up) with clinical assessments and functional tests will be performed. In the event that the participant suffers from COVID-19 during the follow-up, an additional visit will be performed 3 months after the diagnosis, and the final visit will take place 12 months after this additional visit. Determinations: Study factor: diagnosis of COVID-19. Response variable: change in the forced expiratory volume in the first second (FEV1) measured at the start of the study and after 1 year of this first assessment, considering also the basal FEV1 (before March 2020). Other variables: socio-demographic, clinical, functional and treatment. Expected results: Greater decrease in FEV1 in COPD patients with COVID-19, Applicability and Relevance: The proactive detection of functional sequelae will allow early treatment, including pulmonary rehabilitation, with the aim of improving the quality of life of these patients.
Scientific Rationale: In late 2019 and early 2020, researchers at the Wuhan Institute of Virology identified a potential new etiologic agent, called new coronavirus 2019 (nCoV-2019). Subsequently, the epidemic unleashed by this virus involved the whole world and radically changed the habits of the entire global population. Since that time, in fact, the need to contain the spread of infection through specific social distancing procedures and through the use of personal protective equipment has become compelling. The main tool was the requirement for all citizens to wear masks for airway protection. This measure has thus become in daily use for the majority of the population. Therefore, it has become increasingly important to evaluate the impact of mask wearing on activities of daily living (ADls), both in healthy subjects, for which several evidences have already been brought, and in patients with different diseases, for which data are still insufficient to fully describe the effects. Oxygen consumption and dyspnea during simple activities of daily living (ADLs) have already been studied in patients with heart failure (HF) and chronic obstructive pulmonary disease (COPD), and there is evidence that these subjects compared with healthy subjects perform ADLs at a higher percentage of their peak VO2 with more dyspnea. However, there are still no studies highlighting, however, the consequences of performing such activities while wearing a protective filtering facepiece particles class 2 (FFP2) mask, to date considered the most suitable to preserve the most fragile subjects from infection. In this study, therefore, the investigators aim to asess the effects of these devices on the ability to perform ADLs by evaluating the exchanges of respiratory gases in the body during the performance of normal activities or during sleep in patients with HF or COPD compared with healthy subjects.
The purpose of this study is to evaluate the ability of the Bora Care remote monitoring solution to detect early acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD).
The former aim of this study is to determine whether the arm swings change in patients with Chronic Obstructive Pulmonary Disease (COPD) according to healthy subjects. The latter purposes to investigate the correlation between balance parameters and arm swing, how to change arm swing according to severity of the disease, and to determine the relationship between balance and the severity of disease, the relationship of posture both arm swing and severity of disease in patients with COPD. In accordance with this purposes, 20 patients with COPD who have Global Initiative for Chronic Obstruction Lung Disease (GOLD) stage 1-2-3 and 20 healthy controls will be included between the ages of 40 and 65, respectively. Tests and questionnaires will be used in order to determine the severity of COPD and to evaluate posture. Berg Balance Scale, Time Up and Go Test, 6 Minute Pegboard and Ring Test, 6 Minute Walk Test and gait analysis will be performed. It is expected that by determining the parameters that can be affected by severity of COPD. It is estimate to have information about severity of the disease by means of observational analysis. It will guide professional working in the field.
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.
The goal of this observational study is to measure improvement in health related quality of life in moderate to severe COPD patients treated with Trimbow inhalation powder. The main question[s] it aims to answer are: - Treatment's effect on quality of life - Treatment's effect on lung function Participants will be assessed according to routine clinica practice, without any additional intervention.
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.
Given the heightened vulnerability of COPD patients to severe illness upon SARS-CoV-2 infection, precautions like mask-wearing are deemed crucial. Yet, mask-wearing can exacerbate breathlessness and discomfort in this demographic. This study aims to assess the effects of wearing a face mask during 6-Minute-Walking-Tests (6-MWT) among COPD patients.
