The purpose of this study s to determine whether treatment with Iodinated Active Charcoal can improve lung function and physical capacity in patients with chronic obstructive lung disorders. The rational for the study is the observation that COPD patients have an increased tissue load of mercury interfering with the function by NeuroEpithelial Endocrine (NEE) cells in the respiratory tract. Mercury binding to these NEE cells leads to an increased smooth muscle tonus and a reduced response to bronchodilator treatment. Initial observational data have shown an improved lung function and improved functional capacity after treatment motivating a larger placebo controlled POC study
The aim of the study is to investigate the effect of inhaled apocynin on ROS (reactive oxygen species) and NOS (reactive nitrogen species) synthesis in 13 COPD patients. Effects of nebulized apocynin (0.5 mg/ml, 6 ml) were assessed in exhaled breath condensate (EBC) after 30, 60 and 120 minutes.
More patients with chronic obstructive pulmonary disease (COPD) die from cardiovascular disease than direct pulmonary complications. Inflammation and oxidative stress, characteristic in COPD, are likely contributors to the reduction in nitric oxide (NO) bioavailability and vascular endothelial dysfunction in COPD patients; however, this has yet to be determined. Thus, the overall objective of this proposal is to identify the role of NO bioavailability in contributing to vascular endothelial dysfunction in patients with COPD and to provide insight into the molecular mechanisms involved. Our central hypothesis is that inflammation and oxidative stress, both independently, contribute to the reduction in NO bioavailability and vascular endothelial dysfunction in patients with COPD.
Chronic Obstructive Pulmonary Disease (COPD) is the cause of considerable deaths, and exacerbations (flare up of symptoms) are a major cause of hospital admission in the UK. Bacterial infections play an important role in the development of COPD, however, there is little information available about the use of long term antibiotics in the treatment of this disease. Therefore the purpose of this study is to identify the best antibiotic regime for treating patients with COPD who have persistent bacterial infection in their lung. We will test a variety of approaches including both older and newer regimes prescribed either on a daily basis at a lower dose or in "pulsed" courses (for example, every other day or five days every month). The three antibiotics tested in this study are: moxifloxacin, azithromycin and doxycycline. This is a 13 weeks study conducted at the Royal Free Hospital, London. It is expected that approximately 200 patients will be selected for this study. The information we get from this study may help us to treat future patients with COPD better.
This is a multicentre study with a randomised, parallel group, open-label, 3-month phase IV design to assess the efficacy and tolerability of Symbicort as an add-on treatment to Spiriva compare with Spiriva alone in patients with severe chronic obstructive pulmonary disease (COPD).
The Multi-Ethnic Study of Atherosclerosis (MESA) - Chronic Obstructive Pulmonary Disease (COPD) Study aims to characterize the pulmonary vascular changes and their biology in early COPD using imaging, gene expression profiling and peripheral cellular measures.
Patients with moderate COPD as defined by GOLD guidelines constitute almost 46% to 54% of all diagnosed COPD patients. Yet limited data exists on characterizing this study population in terms of drug therapy patterns and COPD-related resource use and costs. The objective of the following study was to conduct an analysis in the real-world setting to (1) identify and characterize COPD patients with moderate exacerbations and (2) evaluate the impact of initiating different maintenance therapies in this population. Maintenance therapy medications include inhaled corticosteroids (ICS), long-acting beta agonists (LABAs), combination of ICS+LABA, and anticholinergics (ACs) including tiotropium (TIO) and ipratropium or combination ipratropium-albuterol (collectively referred to as ipratropium [IPR]).
A study multicenter, phase III, randomized, open label study to evaluate the efficacy and safety of a fixed-dose combination of formoterol/fluticasone and salmeterol/fluticasone in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) that will enroll 336 subjects aged ≥ 40 years, smokers or former smokers, diagnosed with chronic obstructive pulmonary disease, classified as moderate chronic obstructive pulmonary disease or severe according to GOLD spirometric classification. The subjects will be allocated in 2 parallel groups and will receive the medicines of study, according of the randomization during a 24-week.
Some patients with Chronic Obstructive Pulmonary Disease (COPD) report that they are uncertain whether they achieve clinical benefit using a dry-powder inhaler (DPI). One possible explanation is that the patient is unable to inhale the dry powder bronchodilator medication into the lower respiratory tract due to a low peak inspiratory flow rate (PIFR). A PIFR < 60 l/min is considered to be suboptimal flow for a DPI, including the Diskus device. The hypothesis of the study is that the forced expiratory volume in 1 second (FEV1) measured at two hours after inhalation of the study medication will be higher with arformoterol solution (15 mcg) from a nebulizer compared with salmeterol dry powder (50 mcg) inhaled from the Diskus.
