Active clinical trials for "Lung Diseases, Obstructive"

A real world study to determine the effectiveness of a patient support service to aid COPD patients in their self management.

This study assessed whether a short course pulmonary rehabilitation programme with periodic reinforcement exercise training and phone call reminders would help to increase physical activity in COPD patients and also decrease readmissions for AECOPD.

This study evaluates if motivational interviewing sessions aiming to motivate recently discharged patients with either chronic obstructive pulmonary disease or congestive heart failure to be active in post-discharge self-management can reduce re-hospitalization rates.

Aerosol delivery through a ventilator is influenced by numerous factors from ventilator-related, circuit-related to device-related factors. Aerosolized drug delivery through a ventilator system was studied on bench model with albuterol, yet the results were often overestimated. The objective of this study was to evaluate inhaled bronchodilator and mucolytic agents delivered through a ventilator system.

In cigarette smokers that are HIV+, one of the most common HIV-associated non-AIDS conditions is the accelerated development of chronic obstructive pulmonary disease (COPD), a disorder associated with significant morbidity and mortality. Based on the knowledge that COPD in smokers starts in the small airway epithelium, this study is focused on examining the hypothesis that the accelerated development of COPD associated with HIV infection results, in part, from an interaction of HIV directly on the small airway epithelium or through infection of cellular components of the immune system, with mediators released by these immune cells evoking premature biologic aging of the small airway epithelium. By identifying the early events in the pathogenesis of the HIV-associated accelerated COPD in smokers, we aim to identify biologic targets to which pharmacologic therapies could be addressed.

A prospective observational multi centre research study in GP practices clustered within up to 10 UK Primary care trusts.

This clinical trial is designed to determine whether an intervention that provides information to primary care providers about gaps in care for their patients recently discharged from hospital for COPD can reduce hospital re-admissions and mortality and improve their patients' quality-of-life.

Background: In chronic obstructive pulmonary disease, the prognosis for patients who have survived an episode of acute hypercapnic respiratory failure due to an exacerbation is poor. Despite being shown to improve survival and quality-of-life in stable patients with chronic hypercapnic respiratory failure, long-term noninvasive ventilation is controversial in unstable patients with frequent exacerbations, complicated by acute hypercapnic respiratory failure. In an uncontrolled group of patients with previous episodes of acute hypercapnic respiratory failure, treated with noninvasive ventilation, we have been able to reduce mortality and the number of repeat respiratory failure and readmissions by continuing the acute noninvasive ventilatory therapy as a long-term therapy. Methods: Multi-center open label randomized controlled trial of 150 patients having survived an admission with noninvasive ventilatory treatment of acute hypercapnic respiratory failure due chronic obstructive pulmonary disease. The included patients are randomized to usual care or to continuing the acute noninvasive ventilation as a long-term therapy, both with a one-year follow-up period. End points: The primary endpoint is one-year mortality; secondary endpoints are time to death or repeat acute hypercapnic respiratory failure, number of readmissions and repeat acute hypercapnic respiratory failure, exacerbations, dyspnea, quality of life, sleep quality, lung function, and arterial gases.

The sensitivity of a persons cough reflex can be measured by getting them to breath in (inhale) irritant chemicals. The purpose of this clinical research study is to test the sensitivity of the cough reflex to a variety of chemicals that can be inhaled to see if coughing responses are different between healthy people and people with respiratory problems that make them cough.

Pulmonary rehabilitation has been established as an evidence-based and recommended therapy in patients with chronic obstructive pulmonary disease (COPD). The aim of our study is to show a potential change in muscle fibre composition and in the amount of capillaries in quadriceps muscle from pre tob post 3-week rehabilitation. Pulmonary rehabilitation includes standardised exercise training, e.g. cycling and strength training for major muscle groups.
