Filter by:This study assessed the efficacy, safety and tolerability of the co-administration of NVA237 plus indacaterol taken once daily versus indacaterol taken once daily in patients with moderate to severe Chronic Obstructive Pulmonary Disease.
The study is a follow-up of investigations done in the years 1999-2002 in bakery employees. The main purposes are to look at the associations between flour dust exposure and respiratory disease, and to find out the best ways to reduce the flour dust levels in the working environment.
COPD continues to be a cause of major morbidity for patients. Those patients who also have respiratory failure are at higher risk of exacerbations and death and have worse health related quality of life than similar COPD patients without respiratory failure. Treatment options in this group of patients have been limited and data to support the use of machines to assist breathing (non-invasive ventilators) in stable patients are limited. A major limitation of these devices has been patient acceptance and achieving sufficient control of sleep breathing disturbance. Currently devices are set at a fixed pressure to support the breathing throughout the night. The new software within the trial device will aim to better match the support provided by the machine to that needed by the patient. It is hoped that this may offer enhanced comfort as well as superior control of respiratory failure.
The purpose of this study is to create a prospective database of all patients who have undergone pulmonary function testing from which the investigators can study the clinical phenotypes of various respiratory conditions. The investigators hope by understanding the differences in these myriad phenotypes to be able to provide individualized, patient-targeted therapy in the future.
N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive pulmonary disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Randomized, placebo controlled indicate that it is safe and that it may have some clinical benefit when used at relatively low doses. It is postulated that substantially higher doses of NAC will be well-tolerated and will provide better symptom control while also decreasing blood makers of oxidant stress and inflammation.
The main objective of the study is to determine the effects of low-dose oral theophylline added to combination treatment with long-acting β-agonist (LABA) and inhaled corticosteroid (ICS) in patients with severe Chronic Obstructive Pulmonary Disease (COPD) on the rate of exacerbations defined as increase of symptoms that requires a change of medication (antibiotics and/or systemic glucocorticoid) or hospitalisation. DESIGN: Phase III multicenter, randomized, placebo-controlled, double blind, parallel, prospective study. Patient will be recruited during an hospitalisation due to COPD exacerbation and randomised at the time of discharge to receive theophylline 100 mg or placebo on top of combination therapy with inhaled corticosteroids and long-acting beta agonist. The rate of exacerbations will be determined every three months up to one year follow-up. Cl inic visits: every 3 months (total number of clinic visits = 4). In each of them, the following information will be obtained: - Number/severity of exacerbations or hospitalisation since last clinic visit - Compliance and side effects - Blood sample - Plasma levels of theophylline - Sputum (induced) - MMRC - SGRQ - Forced spirometry + inspiratory capacity - At the beginning and at the end of the study - 6MWT - BMI - BODE
The UK population is ageing and the likelihood of having a long term health condition increases with age. Three out of every five people over 60 in the UK have a long term condition. Ageing and having a long term condition increases the chance of having difficulty being independent and carrying out day to day activities. In recent years the NHS has made a greater effort to prevent these difficulties in patients with long term conditions. One approach to help patients with long term conditions is case management, where by (usually) a community matron visits patients at home, looking for early warning signs of any worsening of their condition and arranging care and treatment. But the current way this is done varies across the country and hospital admissions are still rising. In order to give the right care at the right time, effective monitoring is needed to help the community matron detect and act on changes in the patient's condition. Loss of muscle strength in old age is linked to a poor health, but it is not known whether simple measures of muscle strength could be used to detect and predict declines in health in the short to medium term to help maintain independence and prevent an accident or hospital admission. The aim of this study is to look at whether monitoring muscle strength in case managed patients is practical, acceptable and useful in detecting when a patient's condition worsens. Each patient will be visited by the researcher in their home twice in the first week, then once every two weeks, for another 5 weeks, to carry out three simple measures of grip and respiratory strength, and complete questionnaires about their health and ability to carry out day to day activities. Each visit will last about 20 to 30 minutes. A small group of clinicians will be asked about their views of the strength measures. Database analysis will allow descriptive data on the patient group to be gathered and analysed.
The Breathe Ventilator is a lightweight, wearable ventilator that has received U.S. FDA clearance for use in patients with respiratory difficulty. The investigators believe that the Breathe NIOV system will reduce the work of the diaphragm and breathing by providing added tidal volume and oxygen. This will be a study in 14 patients with severe-to-very severe chronic obstructive lung disease (COPD) to assess their work of breathing while using the NIOV system as measured by esophageal and stomach pressures.
REVASC is a randomized, double-blind, placebo-controlled study which will involve 150 patients with chronic bronchitis and COPD diagnosed cardiovascular disease. The recruitment period beginimg in the coming weeks, will last nine months. Patients included in the study will receive treatment for three months with roflumilast 500 mg (75 patients) or placebo (75 patients) in a randomized manner. The CIBERES, as promoter of this study is expected to release final results for the third quarter of 2013. Eight centers in Madrid will be involved in this clinical trial: Fundación Jiménez Díaz, Hospital La Princesa, Hospital Gregorio Maranon Hospital Clinico San Carlos, Hospital La Paz, Hospital Ramón y Cajal Hospital Doce de Octubre and Hospital Puerta del Hierro. Roflumilast is a potent phosphodiesterase-4 inhibitor (PDE4). Its clinical efficacy has been studied in an extensive clinical program involving over 12,000 patients with COPD. In these studies, roflumilast (in combination with long-acting bronchodilators) reduced the number of exacerbations and improved lung function, especially in those patients with associated chronic bronchitis.
In this multicenter study the comparison of the mass flow distribution and redistribution versus the relative blood flow per lobe (as a surrogate for Ventilation/ Perfusion (V/Q) matching) with functional respiratory imaging (FRI) and arterial blood gas (ABG) values will be evaluated in hypercapnic Chronic Obstructive Pulmonary Disease (COPD) patients. Therefore a low dose Computed Tomography (CT) scan will be taken in a population of 30 patients with non-invasive ventilation (NIV) and in a control group of 10 patients without NIV. The CT-scan will be used for FRI.
