Filter by:The two hypotheses to be tested in this study are that: 1. The administration of transcutaneous electrical muscle stimulation (TCEMS) after completion of conventional exercise training in pulmonary rehabilitation (PR) will result in further improvements in exercise tolerance, functional status and symptoms of patients with stable chronic obstructive pulmonary disease (COPD) above those achieved in PR alone. 2. TCEMS can improve exercise tolerance, functional status and symptoms even among COPD patients who fail to make gains in exercise tolerance by participating in conventional PR due to their debilitation and/or marked cardio-respiratory impairment.
Corticosteroid treatment in diabetic patients admitted for COPD exacerbation are expected to significantly increase hemoglobin A1C levels
The purpose of this study is to find out if starting anti-retroviral therapy (ART) above 500 cluster-of-differentiation-4 (CD4)+ cells/milliliter (mL) ('early ART group') slows the rate of decrease in lung function over time compared to waiting to start ART until the CD4+ drops below 350 cells/mL ('deferred ART group'). Lung function normally declines with age, and both human immunodeficiency virus (HIV) infection and ART have been shown to case a decline in lung function as well. Decline in lung function can be an early indicator of chronic obstructive pulmonary disease (COPD), a significant cause of sickness and death in people with HIV. In this study, lung function will be measured at baseline and every year thereafter by using a spirometer.
This is a randomized, double-blind, 3-crossover trial with a 7-days washout baseline period followed by three treatment periods of 21-days each performed in patients with COPD. Patients will be randomized to receive three treatments (bambuterol 10mg, bambuterol 5 mg and placebo).
This multi-center study is designed to describe natural history of disease, treatment and health care products in physician-diagnosed COPD patients who require adding daily maintenance therapy in real world. The study planned to enroll 550 patients in Indacaterol group and 9450 patients in non- Indacaterol group, a total of 10,000 patients. Enrollment was stopped at 2253 patients due to low recruitment in indacaterol group. Finally a total of 2229 patients were analyzed in full analysis set. A total of 2253 patients entered into the database, of which 24 patients were exclude during the data review meetings, because they did not met the inclusion/exclusion criteria. Hence a total of 2229 patients enrolled successfully.
The purpose of this research study is to examine the effects of two weeks of daily dosing of inhaled salt water mist (hypertonic saline - HS) on actual measurements of mucociliary and cough clearance in patients with the chronic bronchitis type of Chronic Obstructive Pulmonary Disease (COPD. Defective mucociliary clearance (MCC) is central to the development and/or worsening of several kinds of lung diseases, including COPD/chronic bronchitis (CB), cystic fibrosis (CF), and bronchiectasis. In each case, defective MCC leads to the development of lung infections and damage to the airways from ongoing inflammation caused by a person's inability to clear mucus from the lungs. The investigators' previous studies have shown that the administration of inhaled HS (hypertonic saline) not only acutely accelerates MCC in CF, but also that repetitive use "resets" the baseline rate of MCC within 2 weeks. It is likely that the sustained effect of HS on MCC was responsible for the ~60% reduction in the frequency of pulmonary disease exacerbations, reduced antibiotic use and improved lung function in a long-term study of HS in CF volunteers. As a result, HS has now become a standard therapy for CF lung disease and its success raises optimism that similar benefits might occur in patients with CB. In this study the investigators will use mildly radioactive particles, technetium bound to sulfur colloid, to measure and compare the sustained effects on mucus clearance of two weeks of daily dosing of 7% hypertonic saline versus a low salt control treatment for subjects with CB. We will also be collecting sputum and breath condensation to analyze for protein and inflammatory changes that might occur with exacerbations. Our long term goals are to improve our understanding of MCC in health and disease and to develop better therapies that support and/or restore MCC in patients with these diseases to reduce lung infections.
Weight loss commonly occurs in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disorder (COPD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in CHF and COPD patients but patients also have reductions in fat mass and bone density, independent of the severity of the disease state. The purpose of this cross-sectional study is to provide detailed insight in disease related gut function by obtaining information on gut permeability, digestion and absorption of glucose, fat and protein in CHF and COPD patients compared to matched healthy controls. This will provide required information that is necessary to implement new strategies to develop optimal nutritional regimen in CHF and COPD. The hypothesis is that CHF and COPD are related to decreased gut function and absorption, leading to decreased anabolic response. Second, this decreased nutritional status is linked to reduced muscle functioning and possibly decreased cognition. In addition, we will examine the effect of aging on by comparing gut function digestion and absorption of the CHF and COPD aged matched healthy controls to a group of young healthy subjects.
The purpose of this study is to determine whether resistance exercise are effective in combating the decline in muscle strength during an exacerbation of Chronic Obstructive Pulmonary Disease (COPD).
The COPD Research Registry is a confidential database of individuals diagnosed with COPD or at risk of developing COPD. The Registry was established in 2007 by the COPD Foundation with the purpose of providing a mechanism for researchers to boost enrollment in clinical trials and other research studies. The COPD Foundation is working with National Jewish Health in Denver, Colorado to serve as the Registry's Data Coordinating Center and to ensure strictest confidentiality of participant information.
The primary objective of this study is to assess and compare the pharmacokinetics (PK) of Tiotropium delivered via Breath Actuated Inhaler (BAI) (4.5 mcg/day or 9.0 mcg/day), SPIRIVA®, HandiHaler®, (18 mcg/day) and Respimat® Soft Mist™ Inhaler (SMI) (5.0 mcg/day) following repeat dosing for 7 days in subjects with COPD.
