Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Obstructive airways disease is a very common condition. This condition includes patients with asthma, chronic obstructive pulmonary disease (COPD), emphysema or chronic bronchitis. Some patients with obstructive airways disease have problems with long term breathlessness, wheeze and cough with or without sputum production. Currently the researchers give treatments - usually inhalers - which are designed to open the airways and reduce the breathlessness and wheeze. Despite these available treatments many patients still have continuing symptoms. Anecdotal clinical evidence suggested that a herbal remedy (called AKL1) has beneficial effects in respiratory conditions, with patients diagnosed as having both asthma and COPD reporting reduced symptoms including breathlessness and cough and reduced frequency of attacks.The purpose of this study is to confirm whether AKL1 does indeed have a meaningful benefit to patients with obstructive airways disease. The researchers will mainly be measuring any effect of AKL by assessing any change in trial subjects' coughs, using a questionnaire, but the researchers will also looking at breathing tests, walking tests, blood and sputum tests.

The purpose of this study is to compare the exercise capacity and pulmonary function test parameters of Chronic Obstructive Pulmonary Disease (COPD) patients who underwent usual care with and without pulmonary daoyin therapy of China in community.

Pulmonary diseases are increasingly important causes of morbidity and mortality in the modern world. Sildenafil, an orally administered a phosphodiesterase type 5 (PDE-5) inhibitor, targets the nitric oxide (NO) pathway. The drug was first approved for the treatment of Pulmonary Arterial Hypertension (PAH) in 2005. The aim of the suggested study is to examine the acute effect of oral intake of sildenafil on exercise tolerance and functional capacity in Chronic Obstructive Pulmonary Disease (COPD), Idiopathic pulmonary fibrosis (IPF) and post Pneumonectomy patients. The investigators hypothesize that oral ingestion of sildenafil prior the exercise may enhance exercise tolerance and improve function in COPD, IPF and post Pneumonectomy patients. Patients and Methods: Sixty chronic lung disease patients males and females (aged 30 to 90 years) 20 COPD (GOLD III-IV) [9, 39] , 20 IPF and 20 post Pneumonectomy patients will be recruit to this study. All subjects will carried out two maximal cardiopulmonary exercise tests (CPET) on bicycle ergometer in different days; 60 min after intake of placebo and 60 min after intake of 100 mg sildenafil (Pfizer, Sandwich, UK), in random order. In first meeting prior exercise test at rest standard pulmonary function test, diffusion of CO, TLC and RV will be measured. In addition, Doppler Echocardiography and blood samples for NT-proBNP will be taken prior and post each CPET. After 15-20 minute of passive recovery post exercise test all patients will perform 3 short functional tests including 6 minute walk test to assess functional capacity.

This study will investigate the effects of positive expiratory pressure (PEP) on hyperinflation in patients with chronic obstructive pulmonary disease (COPD). Inspiratory capacity (IC) is the primary outcome

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by persistent respiratory symptoms and airflow limitation. Pervasive dynamic pulmonary hyperinflation (DPH) and intrinsic positive end-expiratory pressure (PEEPi) can increase inspiratory threshold load and respiratory effort, leading to abnormal changes in respiratory mechanics and neural respiratory drive (NRD). Non-invasive positive pressure ventilation (NPPV) is not only widely used in respiratory failure, but also is one of the important lung rehabilitation strategies. Several studies have reported that the use of biphasic positive airway pressure (BIPAP) mode for NPPV can improve ventilation, reduce NRD, improve NRD coupling, significantly reduce inspiratory muscle load and relieve symptoms. However, relatively few studies are reported that the NPPV is used in COPD patients without non-respiratory failure. Therefore, we suppose that for stable COPD patients without respiratory failure, early intervention with NPPV may reduce DPH, eliminate the adverse effects of PEEPi, reduce the respiratory muscle load, improve the respiratory physiological characteristics, and delay the progression of the disease. Therefore, the purpose of this study is to observe the influence of different levels of BIPAP ventilation on respiratory mechanics and NRD in patients with stable COPD, and to explore whether BiPAP ventilation can be used as a pulmonary rehabilitation method for early intervention of COPD and provide a theoretical basis for subsequent clinical trials.

Chronic obstructive lung disease is a disabling disease that affects people usually after several years of smoke tobacco exposure and affects millions of patients worldwide. The disease is marked by multiples episode of worsening, termed exacerbations necessitating frequent hospitalizations. During these exacerbations, patients present breathless, and in the most severe cases, are admitted to an Intensive Care Unit (ICU) for respiratory assistance. Currently, respiratory assistance is provided by a ventilator via a oronasal mask (referred to non-invasive ventilation, NIV), that helps patients to cope with their breathless. The mask is not always well tolerated and the ventilator sessions are delivered intermittently. In the past decade, a new technique that provides air-oxygen with high flow has been developed. This technique, called High Flow via Nasal Cannula (HFNC) can deliver from 21 to 100% heated and humidified air-oxygen at a high flow of gas via simple nasal cannula. Recent studies have shown that the technique is very efficient to treat patients presenting with acute respiratory failure who don't have any underlying chronic pulmonary disease. Whether the technique would be also efficient in patients with COLD presenting with severe exacerbations has not yet been demonstrated. Since HFNC does not require any mask, it is thought that the comfort of the patient would be much better in comparison to NIV and could potentially help to treat many patients with the disease. The objective of the present study is to study the physiological effect of HFNC as compared to NIV in patients with severe exacerbations of COPD and to show that it is non-inferior to NIV.

Chronic obstructive pulmonary disease (COPD) is a disease state characterized by persistent airflow limitation and associated with an accelerated decline in lung function, impaired quality of life, hospitalization, and increased mortality. As a major public health problem, COPD is predicted to rank as the fifth burden of diseases in the world by 2020. Thus, prevention of exacerbations is a important goal in the management of COPD. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) Scientific Committee launched a joint project in 1998. Its goals were to raise awareness of COPD and to improve prevention and treatment of COPD patients around the world. In the 2017 GOLD guidelines, inhaled long-acting bronchodilators, including inhaled long-acting muscarinic antagonists (LAMAs) and inhaled long-acting beta-agonists (LABAs), are recommended for the management of all stable COPD patients. However, it is not known whether LABA or LAMA will be more effective for initial relief of symptoms in patients with GOLD A/B COPD. In this multicenter, randomized study, the investigators evaluate the efficacy of formoterol(LABA) and tiotropium(LAMA) in the treatment of patients with GOLD A/B COPD. The primary endpoint is postbronchodilator FEV1, and the secondary endpoints include the frequency of COPD exacerbation, other lung function parameters, CCQ score and mMRC/CAT score.

This trial is to investigate the safety and potential therapeutic efficacy of allogeneic administration of umbilical cord-derived MSCs (UC-MSCs) as a supplementary intervention in combination with standard COPD medication treatments in patients with moderate-to-severe COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2019 and Vietnam Ministry of Health's guidelines

This non-interventional study aims to collect information on the patient's quality of life, as well as the quality of sleep when stepping up to a fixed triple maintenance therapy (Trimbow®) as per physicians' decision, independent from study participation, and to assess its effectiveness in daily life, in general practitioner setting.
