Active clinical trials for "Lung Diseases"

This prospective, single centre, 8 weeks, open-label study is designed to evaluate in real-life the effect of triple Beclometasone/Formoterol/Glycopyrronium (BDP/F/G) therapy on cough efficacy, assessed by cough peak flow (CPF), after 8 weeks' treatment in patients with moderate to severe COPD. The study's hypothesis is that in symptomatic moderate to severe COPD patients the administration of fixed dose combination BDP/F/G, by reducing lung hyperinflation (LH) and targeting small airways, may accordingly improve the cough efficacy. The increase in cough efficacy might in turn positively influence the quality of life of patients and underlie the prevention of acute exacerbations of COPD.

The first case of COVID-19 was identified on December 19 and the world is actually experiencing a pandemic. The surgical procedure in patients with SARS-CoV-2 infection involves the exposure of other patients and the group of health workers who face the care of the patient. Thus, screening with lung ultrasound is an alternative to identify patients with an established or suspected infection that requires urgent surgery. Therefore, the aim of this study is to determinate the operational characteristics of lung ultrasound during the screening process for SARS-CoV-2 infection in patients with an indication for urgent surgery.

To characterize stem cell compartments in their niches in different clinical situations (non-diseased compared to emphysematous and fibrotic pulmonary tissue) and to assess their proliferative and developmental properties in vitro. To further implement lung organoid culture system in the drug screening and development of patient personalized medicine.

Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that is characterized by loss of lung function, leading to breathlessness, poor quality of life, loss in productivity, and increased mortality. The World Health Organization estimates that COPD will be the third leading cause of death worldwide by 2020, accounting for more than 7 million deaths annually. COPD patients frequently experience 'lung attacks', during which breathlessness, coughing, and sputum production dramatically increase, leading to urgent office visits, emergency admissions and hospitalizations. Lung attacks reduce patient quality of life and cost the Canadian health care system nearly $4 billion dollars each year in direct and indirect costs. Lung attacks can be effectively managed if they are identified and treated early, but symptoms of a lung attack often overlap with those of other common conditions such as heart failure, pneumonia and even influenza. Because there are no tests that can separate lung attacks from these conditions, doctors struggle to accurately diagnose lung attacks at an early stage when drugs are most effective. This can lead to a delayed or even incorrect diagnosis and inappropriate treatment. This research will address this critical need. Our goal is to improve COPD patient care by developing new blood tests that will help identify patients who are in the early stages of a lung attack. Doctors will be able to use these tests to treat lung attacks at earlier stages than is currently possible. These blood tests will enable doctors to personalize management of COPD to meet the needs of the individual patient. Hypothesis: New biomarker blood tests can be used to better identify and manage patients with COPD.

Chronic obstructive pulmonary disease has become a serious global health care and public health problems due to its high prevalence, high morbidity and heavy economic burden. Acute exacerbation of chronic obstructive pulmonary disease is one of the most important causes of death in patients with COPD. Systemic corticosteroids therapy is recommended in COPD exacerbations. In clinical practice for the treatment of acute exacerbation of COPD， antibiotic application is still controversial. Evidence from current guideline is based on strict criteria from randomized controlled trials, thus the given condition is simplified. Patients meet the criteria account for the minority in the real world. Therefore, it is still not clear whether most patients benefit from the recommended treatment. In our design, hospitalized patients with acute exacerbation of COPD will be enrolled, with their treatment, arterial hypoxemia, recovery time and length of hospitalization being observed. The main purpose is to evaluate the benefit effect of current recommended treatment of acute exacerbation of COPD in the real world.

Development of pulmonary hypertension (PH) in chronic lung diseases has both functional and prognostic implications . PH in Lung diseases is usually mild to moderate with preserved cardiac output, and evolves slowly alongside the progression of lung disease and hypoxemia . However, a minority of patients develop severe PH with elevations in pulmonary artery pressure that have been described as ''out of proportion'' to the underlying disease . The aim of this study is to compare the characteristics and outcomes of consecutive patients with PH-due to lung diseases diagnosed at our specialist referral center over a 1-year period.

The trial shall assess the accuracy of the Oxitone® 1000 in measuring oxygen saturation, by comparing its measurement to reference devices: non-invasive SpO2 and pulse-rate values determined by a pulse oximeter. A total of approximately 40 subjects: 20 healthy and 20 COPD (chronic obstructive pulmonary disease ) patients will be enrolled. These subjects will be enrolled at the medical center pulmonary department and will be recruited from the clinic patient base. The subjects will be represented by male and female adults who optimally cover a range of ethnic backgrounds (skin pigmentation). All testing will be performed in singleton and in a blinded fashion. This study will be conducted with the approval of the medical center ethics committee. This is a comparison open study with no subject follow-up.

COPD patients will be recruited and assigned into one of each group: 1) Control group or 2) Yoga group. In Yoga groups, subjected will be asked to participate in Modified Dantien Yoga training for 12 weeks (3 times/week, 60 min/time). The subjects will be evaluated their pulmonary function, functional fitness performance, dyspnea score, and quality of life at baseline and after 12 wk training.

This work will focus on the anti-inflammatory and antioxidant pathways in lung diseases by measuring HO-1 in induced sputum and CO in exhaled air in cases of four respiratory diseases, asthma, chronic obstructive pulmonary disease (COPD), occupational lung diseases (OLD) and interstitial lung disease (ILD).

COPD is ranked number 3 by the WHO list of important diseases worldwide and is the only disease with increasing mortality. The pathogenesis of cigarette smoke-induced COPD is obscure, therefore more insight is needed to design effective anti-inflammatory agents. Recently it has become clear that cigarette smoke-induced inflammation is not only present in the lungs but also in the blood, and that this systemic inflammation has important consequences for the clinical expression of COPD. The investigators hypothesize that healthy individuals who are susceptible to cigarette smoking demonstrate a higher and aberrant systemic inflammatory response to cigarette smoke. This susceptibility is caused by heterogeneous factors and is associated with various polymorphic genes that interact with each other and with the environment. Objective: To study systemic inflammation in individuals who are or are not susceptible to develop COPD. To characterize the switch to chronicity of the systemic inflmmatory response in COPD To determine whether the type and severity of the systemic inflammation contributes to the clinical outcome of COPD To compare between subjects who are or are not susceptible to develop COPD in peripheral blood, the corticosteroid responsiveness in vitro, and to unravel underlying mechanisms. To study the role of candidate genes that may play a role in the development of fixed airway obstruction, and to identify clues for patient's responsiveness to specific drugs To develop new biological and clinical markers for the early diagnosis and monitoring of COPD To define possible mediators involved in the early induction of COPD in susceptible smokers, and to define new drug targets
