Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

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.

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.

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.

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 study is designed to determine whether the optimized inhalation therapy based on peak inspiratory flow rates (PIFR) measured against the simulated resistance can reduce the rate of treatment failure in patients recovering from acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Errors in inhaler use and quality of life are also to be evaluated. The study will recruit 460 patients with AECOPD whose exacerbated symptoms are relieved by 5-7 days of standard therapy. The participants are divided into PIFR group and control group in a 1:1 ratio according to a random number table method. All the patients will be given inhaled corticosteroid（ICS）/long-acting β agonist（LABA） (budesonide/ formoterolSymbicort turbuhaler® 160/4.5 μg bid or Beclometasone/ Formoterol Foster® pressure metered dose inhaler(pMDI) 100/6 μg 2 puff bid). For symptomatic patients before acute exacerbation, Spiriva handihaler® 18μg qd or Spiriva respimat® 2.5μg qd will be prescribed in combination with ICS/LABA. For PIFR group, PIFR is measured by InCheck DIAL(Clement Clarke International Ltd, Harlow, UK and Alliance Tech Medical). If PIFR is less than 60L/min , the patient will be given pMDI with spacer. If PIFR value is over 60 L/min, the patient will be given dry powder inhaler(DPI).). The control group will be given DPI or pMDI with spacer according to the judgment of a respiratory physician. Both groups will be taught to use the device after the prescription, and then be reminded to use medication via a WeChat public account. The primary endpoint of the study is the 30-day treatment failure including AECOPD recurrence resulting in an emergency visit, admission, or need for intensified medication). The secondary endpoints of the study are the error rate of inhalation device use, satisfaction with inhalation devices, symptoms and quality of life, 30-day mortality, chronic obstructive pulmonary diseases(COPD)-related treatment costs and PIFR.

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.

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.

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.

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.
