Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The study null hypothesis is that vitamin D supplementation will not influence time to upper respiratory tract infection or time to moderate/severe exacerbation of chronic obstructive pulmonary disease.

Some groups reported that sniffer dogs can be applied to detect lung cancer in the exhaled breath of patients. Therefore, breath samples (BS) of patients are collected. Five sniffer dogs are trained to distinguish between the BS of patients with lung cancer and healthy individuals (controls). In a prospective, randomized blinded study the dog's ability to differentiate between BS of i) patients with lung cancer, ii) patients with inflammatory airway disease, but no evidence of cancer and iii) healthy individuals is tested.

PEP03 is a new chemical entity developed as a highly selective, potent, and orally active 5-LO inhibitor. PEP03 exerts its action by blocking the generation of both cysteinyl LTs and LTB4. These LTs have been associated with the inflammatory response in the lung and with the clinical sequelae, including bronchospasm. Preclinical pharmacological in- vitro, ex-vivo and in-vivo testing indicates that PEP03 has multiple beneficial actions including prevention of bronchoconstriction, and reduction of vascular leakage, cellular infiltration, and bronchial hyperresponsiveness. Clinical studies in asthmatic patients indicate that PEP03 improved FEV1 and other secondary endpoints, such as morning and evening peak flow, daytime and nighttime symptoms score, beta-agonist use, physician's and patient's global impression of change. Since leukotrienes have been suggested to be involved in the pathophysiology of COPD, this study is designed to explore the clinical utility of PEP03 for the treatment of moderate COPD.6; 7; 8; 9

The purpose of the study is to investigate, in patients with moderate to severe chronic obstructive lung disease, whether intermittent antibiotic treatment leads to: A slower rate of decline in forced expiratory volume in one second (FEV1); A reduction in the frequency and severity of exacerbations; Fewer hospital admissions for chronic obstructive pulmonary disease (COPD); Lower mortality; An improved quality of life as compared to a group of placebo treated patients.

The purpose of this study is to evaluate the changes of lung function before and after the exercise in patients with chronic obstructive pulmonary disease.The assessment of quality of life is also carried out through questionnaires.

Chronic obstructive pulmonary disease (COPD) is a common chronic disease with a significant medical and economic impact. Its prevalence is increasing and is estimated at 7.5% of people over 40 in France. COPD is responsible for a significant impairment of quality of life and was the 3rd leading cause of death in the world in 2010 when it was 4th place 20 years ago. However, about 75% of patients with COPD are not diagnosed. Spirometry is the only examination for the diagnosis of COPD. Patients identified at risk for COPD are insufficiently using spirometry and general practitioners (GPs) underestimate the severity of COPD when they do not practice spirometry in their patients. COPD is often diagnosed too late, the disease being discovered at the stage of complications requiring hospitalization. The underdiagnosis is mainly due to poor knowledge of patients, their difficulty in accessing a specialist performing spirometry, their reluctance to perform spirometry, and the insufficient involvement of general practitioners. Currently in France, targeted screening for COPD and diagnosis in primary care is a major challenge. The international (GOLD 2014) and French (HAS 2014) recommendations do not indicate a systematic screening in the general population for COPD but advocate targeted screening of patients by five questions to identify risk factors and symptoms of COPD. The presence of at least one of these factors in an adult over the age of 40 requires spirometry. Recent studies suggest the relevance of finding primary care variables for smoking and respiratory symptoms in order to identify new cases of COPD. However, the impact of the use of these questionnaires on the prevalence of diagnoses of COPD in general practice has not been demonstrated. Moreover, the heterogeneity of the provision of care according to the territories limits a fast or easy access (distance) to the spirometry. It is therefore necessary to evaluate in primary care the interest of a targeted screening of COPD and the interest of a coordination of care for the realization of a spirometry, in order to improve the rate of diagnosis of the disease.

Many "Survivors" in the World Trade Center (WTC) clinical program have a clinical syndrome characterized by chronic obstruction in small airways and persistence of lower respiratory symptoms despite therapy. This study will test the hypothesis that persistent symptoms in WTC "Survivors" are associated with abnormal small airways whose dysfunction is amplified during exercise and is associated with biologic evidence of inflammation and remodeling. The results from this study will have important treatment implications for our WTC population with potential applicability to larger populations with either inhalational lung injury and/or airway diseases such as asthma and chronic obstructive pulmonary disease.

The purpose of this study is to test whether the three-seeds mixture tea reduces sputum and/or cough in COPD patients, and if so, to evaluate whether the three-seeds mixture changes the lung microbiome.

In this study, patients with Chronic Obstructive Pulmonary Diseases (COPD) in stable and acute exacerbation stage were selected as the research objects, and the open, parallel and randomized controlled clinical trial design was adopted. Participants were randomly divided into trial group and control group. The control group was only given routine education, and the experimental group, on the basis of routine education, developed a respiratory rehabilitation training program lasting for 12 weeks according to the individual situation of patients. All participants were interviewed for 6 times (baseline and 4,8,12 weeks, 6 months and 12 months after admission) for a period of 1 year. Acute exacerbation, activity tolerance (6-minute walking test), living environment, clinical symptoms, lung function, airway inflammation water level index and biological samples were collected at each visit. At the same time, according to the diary filled in by the patients, the investigators can obtain the daily stay time indoors and outdoors and the longitude and latitude information of the regular stay fixed place, and geographic information system (GIS) is used to match the nearest environmental monitoring station, obtain the data of air pollutants and meteorological indicators (SO2, NO2, Co, O3, PM10, temperature and humidity, etc.), and estimate the individual exposure level of air pollutants.

This trial aims to evaluate the clinical control rate of sputum by Zhuli Capsule in the treatment of the Phlegm-heat Syndrome （Tan-re Zheng）in the patients with acute exacerbation of chronic obstructive pulmonary disease or chronic bronchitis.
