Filter by:Objective: is to find out the effect of unsupported upper extremity exercise versus lower extremity exercise on dyspnea and lung function Methodology: Sample and design: 60 patients with Randomized study design will be included in three groups. Duration of intervention: Treatment will continue for 4 weeks. Outcome: Borgs scale and Medical Research Council scale (MRC) for dyspnea will be used to quantify the dyspnea. Lung function tests measure by PEFR, chronic obstructive pulmonary disease assessment test (CAT) will be used pre-post. Discussion: We will compare three groups (UPPER EXTREMITY EXCERCISE (UEx), LOWER EXTREMITY EXERCISE (LEx), CONTROL (CON)) with COPD using interventional exercises for upper and lower extremities randomly assigned to three groups on the dyspnea symptoms and quantify and grade them pre-post the intervention. We will also use the CAT questionnaire pre-post to measure the changes in symptoms and functions.
This is a single-centre, double-blinded, randomised, placebo controlled trial comparing mepolizumab 100mg versus placebo in patients with eosinophilic COPD, started following their index admission to hospital.
This cross-sectional study aims to investigate what daily activities increase the risk of falling in Chronic Obstructive Pulmonary Disease patients (COPD).
The aim of the present study is to examine whether the nature based 'Wild man Programme' can help to increase quality of life among men on sick leave compared to treatment as usual. Additionally, the study examines which natural environments best work as supportive environments in the rehabilitation.
Research question Is there any association between altered lung bacterial communities and HIV-associated Chronic Obstructive Pulmonary Disease (COPD)? Rationale Sub-Saharan Africa has experienced dramatic increases in COPD related-morbidity and mortality. Longitudinal studies have shown that people living with HIV develop worsening airflow obstruction with a prevalence higher than that of the general population (i.e 3.4 to 21% compared to 0.4 to 12.2%). It is still unknown why HIV-infected individuals develop COPD at a prevalence higher than their HIV-negative counterparts. It's been hypothesized that a change in the lung bacterial communities in the setting of HIV drives inflammation leading to lung damage. There is a need to explore the dynamics of lung bacterial communities and elucidate mechanisms responsible for irreversible lung damage that may follow lung disturbances in bacterial richness and diversity. In addition, understanding the bacterial communities of the lung in normal subjects is an essential step in providing negative controls to interpret lung microbe in disease states for-example COPD. Insights from this research will inform efforts to design optimal screening and treatment strategies for COPD in the HIV-infected population in sub Saharan Africa. Methods A cross sectional study will be conducted in which lung bacterial communities in 63 HIV infected participants ≥ 35 years with and without COPD will be compared with 63 HIV negative participants with and without COPD. Participants will be recruited from COPD/HIV and LINK Nakaseke cohorts, which were population based studies conducted in the same study setting. Sputum samples will be collected using sputum DNA collection, preservation and isolation Kits. Extracted bacterial DNA will be sequenced and used to determine all bacterial species in the processed samples using available online metagenomics databases. Analysis plan A histogram will be used to display the frequencies of the identified bacterial species in the processed samples. Bacterial richness and diversity of samples in the 4 groups will be compared to determine any differences.
A multi-center, randomized, 72-month, parallel- group, non-inferiority, phase III study to compare the effectiveness of roflumilast (Daliresp, 500 mcg quaque die (QD) or alternate regimen) therapy versus azithromycin (250 mg QD, 500 mg QD three times per week, or alternate regimen) to prevent hospitalization or death in a patients at high risk for COPD exacerbations.
Chronic obstructive pulmonary disease (COPD) is a progressive disease of the respiratory system that generally develops as a result of smoking. Most people with COPD are classified as having "mild" disease severity and may not have significantly impaired lung function (e.g. flow) as measured by traditional lung function tests. However, multiple studies have shown that patients with mild disease already have significant damage to the small airways and blood vessels of the pulmonary system. This results in a considerable portion of the lung that does not participate in gas exchange, a phenomenon called physiologic dead space. Mild COPD patients develop symptoms of intolerable breathlessness early in exercise compared with healthy individuals. Previous studies have shown that pulmonary vasodilators, which locally increase blood vessel radius, may improve gas exchange and reduce symptoms of breathlessness in patients with mild COPD. Therefore, the objective of this study is to determine the effect of reducing dead space with a pulmonary vasodilator on the intensity of breathlessness during exercise in patients with mild COPD. This five visit, double-blinded, placebo-controlled crossover study will test the impact of inhaled nitric oxide, a direct vasodilator, during cardiopulmonary exercise on dead space and breathlessness intensity. Use of an esophageal catheter during testing will additionally permit measurement of neural drive to breathe and pulmonary mechanics throughout the protocol. Though patients with mild COPD represent the majority of the COPD population, their symptoms remain poorly managed by current, inefficient standard of care. The proposed study will examine dead space reduction as a novel therapeutic target for improving breathlessness and exercise tolerance in patients with mild COPD.
The purpose of this protocol is to test the safety, pharmacokinetics, and pharmacodynamics of the Cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, ivacaftor in patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis. This project will investigate the hypothesis that ivacaftor can augment CFTR activity in individuals with COPD who exhibit chronic bronchitis, resulting in meaningful improvements in epithelial function and respiratory health. The study is a multicenter, randomized, double-blind, placebo-controlled, stratified study of orally-administered ivacaftor.
This study aims to assess the anti-inflammatory effects after 6 weeks treatment with tiotropium compared to placebo in patients with stable COPD
Phase 3 study to evaluate the efficacy and safety of a benralizumab in patients with moderate to very severe COPD with a history of frequent COPD exacerbations and elevated peripheral blood eosinophils (≥300/μL). Eligible patients must have a history of ≥2 moderate and/or severe COPD exacerbations in the previous year despite receiving triple (ICS/LABA/LAMA) background therapy for at least 3 months and ICS-based dual inhaled treatment for the remainder of the year. Eligible patients must also have an elevated blood eosinophil count. The treatment period will be of variable duration and will continue until the last patient has the opportunity to complete a minimum of 56 weeks, at which point all patients will complete the study. The primary endpoint will be analyzed at Week 56.
