Filter by:- Among many other causes, Bronchial obstruction in Chronic Obstructive Pulmonary Disease (COPD) is also caused by inflammation of peripheral airways walls. - Neutrophils and other inflammatory mediators like Interleukin-6 (IL6), Interleukin-8 (IL8), Interleukin-1 alpha (IL-1 alpha),Interleukin-1beta (IL-1 beta), Tumor Necrosis Factor alfa (TNF-alfa), Reactive Oxygen Species (ROS), Leukotriene B4 (LTB4), Nitric Oxyde (NO) are implicated in the inflammation. - NO is produced in response to physical and chemical stress on bronchial epithelium and plays a critical role in small airways remodelling - Exhaled NO concentration is usually used to monitor bronchial inflammation - The relationship between stretch and strain of small airways and bronchial inflammation is not well understood. - The investigators hypothesis is that cyclic opening and closure of peripheral obstructed airways through the consequent stretching and strain acting on them can provoke an inflammatory response which can be monitored by exhaled NO. - The pharmacological effects of bronchodilators may play a role on bronchial inflammation by reducing the stretching stress on bronchiolar walls thus reducing the production of NO in exhalate - Data about these physiopathological aspects is missing in literature.
Influenza disease causes significant morbidity and mortality in the Unites States each year. Although influenza can cause morbidity in otherwise healthy individuals, adults with chronic lung disease have significantly increased rates of hospitalization from influenza-related illnesses compared to healthy adults. Influenza vaccination is the primary means of preventing influenza disease. Annual influenza vaccination is recommended for all individuals 6 months of age and older in the United States. Influenza vaccination rates are sub-optimal, however. Patient reminder/recall has been shown, in multiple studies across a variety of age groups and health conditions, to increase immunization rates. However, the effectiveness and cost-effectiveness of different types of reminder/recall has not been well-studied, particularly in adults. In the fall of 2012, the Population and Prevention Services (PPS) Department at Kaiser Permanente Colorado (KPCO) is using 3 different reminder strategies for influenza vaccination among adults with asthma and chronic obstructive pulmonary disease (COPD). The objective of this study is to provide a rigorous evaluation of which strategy is more effective and more cost-effective, to promote influenza vaccination.
Conventional approaches to relieve dyspnea (respiratory discomfort) in chronic obstructive pulmonary disease (COPD) have focused on improving respiratory motor drive (e.g., hyperoxia) and/or dynamic respiratory mechanics (e.g., bronchodilators). Although these approaches yield meaningful symptom improvements there remains many COPD patients incapacitated by dyspnea. Accumulating evidence suggests that abdominal binding (AB) is a potentially novel method of improving respiratory muscle function and, by extension, dyspnea and exercise tolerance in COPD. Thus, the purpose of this randomized, cross-over study is to test the hypothesis that AB improves exertional dyspnea and exercise tolerance in symptomatic patients with COPD by improving dynamic respiratory muscle function. To this end, the investigators will examine the effects of AB on detailed assessments of baseline pulmonary function (spirometry, plethysmography), dyspnea (sensory intensity & affective responses), neural respiratory drive (diaphragm EMG), contractile respiratory muscle function (esophageal, gastric & transdiaphragmatic pressures), ventilation, breathing pattern and cardiometabolic function during symptom-limited constant load cycle exercise (75% Wmax) in 20 patients with GOLD stage II/III COPD.
The investigators designed the current study with the main objective of determining whether Whole Body Vibration Training (WBVT) alone improves muscular force and/or modifies the functional capacity parameters in severe Chronic Obstructive Pulmonary Disease (COPD) patients referred to a rehabilitation programme.
It is a phase IV clinical trial: longitudinal, prospective, evaluator-blind, randomized into 2 groups of patients with chronic obstructive pulmonary disease (COPD). The intervention group was based on the administration of roflumilast 500 mcg per day on alternate days (roflumilast 500μg eod) for 2 weeks (phasing). In the control group assigned to undertake the treatment according to the standard dosage (roflumilast 500μg od). The patient monitoring will be done by one of the sub-investigators fully independent team that started the medication keeping the pattern masking by single blind, and since it aims to assess the frequency of adverse events (AEs) in both groups were collected systematically different AEs and their characteristics at 15 days (V1), and from that moment a month (V2) and 2 months (V3). Likewise, other data collected (functional demographic, comorbidities, home treatment, anxiety and depression and quality of life). The purpose of this study is to assess whether the administration of roflumilast by a gradual pattern varies the incidence of discontinuations due to adverse events when compared with the usual dosage.
chronic obstructive pulmonary disease (COPD) is typically associated with mucus hypersecretion in the airways. In health, mucin is the major macromolecular component and is responsible for the protective and clearance properties of the mucus gel. In a recent study the investigators found that mucins are decreased and unstable in the sputum of adult cystic fibrosis (CF) patients. In this study the investigators want to investigate the differences on the mucin quantity and quality of airway secretions during pulmonary exacerbation of patients with COPD.
The primary outcome for this project will be the development of a small, non-invasive wireless sensor that is linked to a conventional computer that can be used in health care for monitoring of acute and chronic health problems. The advantages of developing this technology are threefold. First, monitoring can be conducted for a fraction of the cost of a bedside nurse. Second, monitoring can be done in real time and stored so that we can diagnose and manage critical events in a more timely manner. Lastly, many patients can be monitored simultaneously. The wireless sensors will be fitted to healthy volunteers of various ages. The data gathered from the sensor with respect to their vital signs will be compared to that of conventional tools such as nursing assessments and pulse oximetry.
The purpose of the study is to evaluate the efficacy and safety of a biological vaccine (MV130 in subjects with Chronic Obstructive Pulmonary Disease (COPD) compared with a placebo group.
Study is to show that QVA149 is superior to the standard of care, fluticasone/salmeterol, in patients with moderate to severe airflow limitation
The purpose of this clinical trial is to demonstrate hyperpolarized xenon (HXe) as a medical imaging drug (agent) for Magnetic Resonance Imaging (MRI) of the human lung ventilation.
