Filter by:The purpose of this study is to assess innovative treatment methods in patients with adult respiratory distress syndrome (ARDS) as well as those at risk of developing ARDS.
The aim of the study is to observe the ventilatory and cardiac function (included the pulmonary arterial pressure) during an intermittent work exercise test with high density work load.
This is a 3 year longitudinal study to identify novel endpoints and compare these with standard measures such as forced expiratory volume in 1 second (FEV1) for their ability to measure and predict COPD (Chronic Obstructive Pulmonary Disease) severity and its progression over time. Control subjects (smokers and never smokers) will be recruited as comparators with the COPD subjects.
The objective of this trial is to compare the efficacy and the safety of Ba 679 BR Respimat 5 ug once daily to tiotropium inhalation capsule 18 ug (Spiriva inhalation capsule) in a crossover study of 4-week treatment periods in patients with COPD.
The purpose of the study is to compare histone acetyltransferase (HAT) and histone deacetylase (HDAC) expressions and activities in induced sputum macrophages obtained from patients with moderate to severe COPD and age-matched normal non-smokers
We want to study the effect of the combination of metoprolol (a beta-blocker) with formoterol (a beta-agonist) on long function in patients with Chronic Obstructive Pulmonary Disease (COPD). There are more and more clues that a beta-blocker, when well chosen and in the right dosage, won't harm the long function in patients with COPD. Since a beta-blocker can be a valuable addition to treating patients with heart problems we would like to see if this category of medication can be available for COPD patients in the future.
Chronic obstructive pulmonary disease (COPD) is a disease state characterized by airflow limitation that is not fully reversible. Acute exacerbation of COPD (AECOPD) with increasing symptoms like dyspnea, cough and sputum is the natural history of the disease and incurs significant burden to our health care system. In Hong Kong, COPD was the 5th leading cause of death, and accounted for at least 4% of all public hospital acute admissions in 2003. Previous studies have shown that pulmonary function and quality of life were adversely affected by frequent exacerbations. Strategies to decrease the heavy use of health care resources is urgently needed for the benefits of the patients and the society. Pulmonary rehabilitation programme (PRP) is a multidisciplinary programme of care for patients with chronic respiratory impairment. In COPD patients, the programme can be tailored individually and can optimize each patient's physical and social performance and autonomy. Previous studies on patients with stable COPD found that a PRP including education and physical training could lead to statistically significant and clinically meaningful improvements in health related quality of life and exercise capacity. COPD patients who just have experienced an episode of acute exacerbations are at high risk of developing another attack. There has been only one randomized controlled study looking at the effect of out-patient PRP for patients immediately after an exacerbation. It has shown that PRP immediately after an exacerbation was safe and improved the exercise capacity and the quality of life at 3 months. However, the follow up duration of the study was short and thus the effect of rehabilitation on recurrent exacerbations and hospitalizations is not assessed and this information is important. The investigators would thus like perform a randomized controlled trial to assess if a short course (for 6 weeks) out-patient PRP for patients admitted to acute hospital for AECOPD could have a positive impact on the patients by decreasing their health care resources utilization (recurrent COPD exacerbations, hospitalizations and accident and emergency department [AED] attendance) and improving the quality of life of the patients over a period of 1 year. Patients will be randomized to either a control group or PRP intervention group. It is hope that the information generated from this study will be able to give a guide to whether short course PRP is effective for the patient (in terms of quality of life) and the health care system (in terms of health care utilization).
This study is to be conducted in subjects with mild-to-moderate COPD who are cigarette smokers with the intent of demonstrating differences in smoking cessation between varenicline and placebo.
