Active clinical trials for "Lung Diseases"

Study to assess the long-term safety and effectiveness of Spiolto in Japanese patients with Chronic Obstructive Pulmonary Disease (COPD) in real-world setting

This purpose of this study is to obtain inhalation profiles in subjects with very severe Chronic Obstructive Pulmonary Disease (COPD). This is a study with no investigational medicinal product. Each subject will attend the clinic on 2 occasions, initially for a screening visit and then for further assessments if included (Visit 1). The maximum time that a subject may be enrolled in the study is 33 days from the screening visit to follow up.

Design studies of nebulization in COPD does not respond adequately to the clinically relevant question: the intervention of administering nebulized bronchodilators at home it is likely to make a profit, compared to the standard optimized treatment as defined by the recommendations of the SPLF, patients with severe COPD (stage III, FEV between 30% and 50% of the theoretical value) and very severe (stage IV, less than 30% of the theoretical value FEV)? The concept of profit in this context is based on criteria of dyspnea, quality of life, use of health system (exacerbations, hospitalizations, prescription of antibiotics and steroids ...).

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.

During the previous phases of the project (Phase I and II), two new field tests have been designed and validated for an integration in a primary care setting in Chronic Obstructive Pulmonary Disease (COPD). These new field tests are 3-min paced-walk test (3MPWT) and 3-min paced step test (3MPST). If the validity and sensitivity of the TM3 could be highlighted, particularly by the reduction of dyspnea level following bronchodilatation, Phase II highlight that the 3MPST does not allow to detect this decrease of dyspnea after bronchodilatation. The use of too high step rates could explain these results through a hypothesis relative to neuromechanical coupling of dyspnea. The main objective of this trial is to follow the investigations on the sensitivity of 3MPST to detect the effects of pharmacological intervention on the exertional dyspnea in COPD patient. The hypothesis of this work is that the use of lower step rates cadences could allow to detect an improvement of exertional dyspnea following treatment-induced bronchodilatation, contrary to higher step rates.

The purpose of this project is to investigate whether a 12-week, fulltime pulmonary rehabilitation program can enhance cognitive functioning, mood, anxiety, and quality of life in patients with Chronic Obstructive Pulmonary Disease (COPD).

The purpose of this study is to investigate how inspiratory flow pattern influences CO2 elimination in people without primary lung disease. The hypothesis is that a long mean distribution time, caused by a long postinspiratory pause and high end-inspiratory flow, will promote CO2 exchange in the alveoli.

In the investigators' knowledge there are no data about the impact of non invasive mechanical ventilation on the breathing-swallowing interaction. Our main objective is to evaluate breathing-swallowing interaction in Chronic Obstructive Pulmonary Disease (COPD) patients hospitalized in intensive care unit for an acute exacerbation, and evaluate the impact of using non invasive mechanical ventilation (NIV)

This study will examine bacteria and toxins in the mouth, lung and digestive system that may be the cause of various diseases or symptoms. H. pylori is a bacterium that produces various toxins that may contribute to lung problems. This study will examine specimens collected from the mouth, teeth, lung, digestive tract and blood to measure H. pylori and its toxins and their effects on cells. People 18 years of age and older with or without gastrointestinal disease may be eligible for this study. These include people without a history of lung disease as well as patients with any of the following: lymphangioleiomyomatosis, asthma, sarcoidosis, other chronic or genetic lung disease (e.g., chronic obstructive pulmonary disease, cystic fibrosis or eosinophilic granuloma). Participants may undergo the following tests: Blood and urine tests, chest x-ray. Measurement of arterial blood gases: A small needle is placed in an artery in the forearm to collect arterial blood. Lung function tests: Subjects breathe deeply and occasionally hold their breath. They may also receive a medication that expands the airways. Fiberoptic bronchoscopy with lavage and bronchial brushing: The subject's mouth and throat are numbed with lidocaine; a sedative may be given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways. Saline (salt water) is then injected through the bronchoscope into the air passage and then removed by gentle suction. Next, a small brush is passed through the bronchoscope and an area of the airway is brushed to collect some cells for examination. Mouth rinsing or teeth brushing to collect cells. Endoscopy: A small needle and catheter (thin plastic tube) are placed into an arm vein to administer fluids and medications through the vein. A sedative may be given. The throat is numbed with lidocaine and a thin flexible tube called an endoscope is inserted through the mouth and down the esophagus into the stomach and upper part of the small intestine to examine those areas.

The purpose of this study is to evaluate the multiple mechanisms through which stress, physical environment, and genetic predisposition contribute to asthma in urban children.
