Filter by:Chronic obstructive pulmonary disease (COPD) is a chronic condition involving an impairment in functionality and in the execution of activities of daily life. The hypothesis of this study is to examine the relationship between cognitive status and clinical profile (respiratory, sleep quality, nutritional status) in patients with chronic obstructive pulmonary disease in two different moments: exacerbation or stable situation.
The purpose of this study is to investigate the effect of travelling to moderate altitude and of nocturnal oxygen therapy during a stay at moderate altitude on exercise performance of patients with pulmonary hypertension or with interstitial lung disease.
The purpose of this study is to investigate the effect of nocturnal oxygen therapy during a stay at moderate altitude on exercise performance of patients with chronic obstructive lung disease.
This study will test whether using the Biodex BioStep Semi Recumbent Elliptical for the chronic obstructive pulmonary disease (COPD) patient with arthritic limitations will improve participation in a pulmonary rehab program compared to the Nustep elliptical. The main outcome of participation will be measured by the number of exercise sessions the patient is able to complete during their pulmonary rehabilitation program. In addition, distance walked in six minutes, dyspnea score, rate of perceived exertion (RPE) score, Pain Scale Index score, and finally, the Dartmouth Quality of Life index (DQL) will be assessed in both groups. It is believed that the new machine will provide better overall outcomes compared to the traditional machine.
The purpose of the study is to determine if benralizumab reduces COPD exacerbation rate in symptomatic patients with moderate to very severe COPD who are receiving standard of care therapies
Scarring of the lungs is common in patients with scleroderma and is one of the main causes of death. Patients with scleroderma very frequently have problems with their gullet (esophagus), the food pipe that leads into the stomach. Normally, a small circular muscle at the base of the esophagus opens to allow food to pass into the stomach and closes to keep the digestive fluids from flowing back up into the gullet. In patients with scleroderma, the muscle may become weak and no longer close properly. Gastroesophageal reflux (GER) is the medical term for reflux of stomach contents into the esophagus. Our hypothesis is that small amounts of GER can move back up into the esophagus and get inhaled into the lungs, and may be one of the triggers for lung scarring. We propose to look for certain substances normally only found in the stomach in the "exhaled breath condensate" which is collected by breathing comfortably into a cooled cylinder, allowing the breath to condensate. In a smaller group of patients, we also plan to perform a bronchoalveolar lavage, a more widely studied test in which a small amount of fluid is introduced into a small part of the lungs through a fine tube, and then removed for examination, to evaluate whether the two tests provide similar measurements. We will also evaluate the correlation between these molecules and other tests, including lung function, and markers of lung scarring activity, and tests to look at how the esophagus is working so that we can get a clearer picture of how this affects patients' daily lives. Finally, we will be following up patients over time with lung function to see whether evidence of GER into the lungs is linked with a greater likelihood of worsening of lung scarring in the future.
Hospital readmissions for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) pose burdens to the healthcare system and patients. The aim of this study was to determine whether a screening and educational tool, administered prior to discharge, would result in a decrease in the rate of hospital readmissions.
The study is a randomized, double-blind, placebo-controlled, multiple-dose, pilot study of orally-administered ivacaftor in subjects with chronic obstructive pulmonary disease. Subjects will be administered the study drug ivacaftor 150 mg (or placebo) twice daily (BID).
This project (funded by the IWT-TBM program) will organize a randomized placebo-controlled multicenter intervention trial in 500 COPD patients to study the effectiveness and safety of azithromycin therapy in the acute setting of COPD exacerbations requiring hospital admission. Although long-term use of azithromycin is proven effective to prevent exacerbations, inherent risks outweigh the benefits. By reducing the dose and duration of the azithromycin treatment and by restricting the treatment to acute periods with highest risk for treatment failure, benefits may counterbalance potential side effects, which may result in a new treatment strategy for these acute events. The present study is designed by the services of respiratory medicine of the Leuven and Ghent University hospitals but will run in total in 17 different large hospitals in Belgium, of which 12 are located in Flanders.
Pharmacologic treatment of asthma and COPD is based mainly on inhalations. The aim of the study is to determine if short training of inhalation technique in patients with obstructive diseases may influence the course of asthma and COPD.
