Active clinical trials for "Lung Diseases"

Alpha 1-antitrypsin-deficient individuals develop severe destructive lung disease much earlier and their lung function declines faster than the general population of individuals with chronic obstructive lung disease. This study is designed to better understand the pathogenesis of lung destruction in alpha 1-antitrypsin deficient individuals and to characterize the pathobiology of early lung destruction. To accomplish this we intend to use bronchoalveolar lavage to determine and quantify the factors that initiate and sustain lung inflammation in alpha 1-antitrypsin deficient individuals with lung function above a force expiratory volume in one second (FEV1) of greater than 50% of predicted.

The primary aim of our study is to examine the relationship between balance and respiratory function, respiratory and peripheral muscle strength, functional capacity, and cognitive function in patients with Chronic Obstructive Pulmonary Disease (COPD). The secondary aim of our study is to compare respiratory function, respiratory and peripheral muscle strength, functional capacity, balance, and cognitive functions of COPD patients and healthy individuals. This study will examine and record the participant's sociodemographic information and medical records. Balance, respiratory function, respiratory and peripheral muscle strength, functional capacity, and cognitive function will be assessed. Since the patients are included in this study, no intervention will be made, no additional tests will be performed, or no changes will be made in the routine treatments of the patients during the study.

The primary objective for this trial is to investigate the incidence probability of progression to Progressive Fibrosing Interstitial Lung Diseases (PF-ILDs) in patients with fibrosing ILD other than Idiopathic Pulmonary Fibrosis (IPF) in real-world setting in Japan. The secondary objective is to investigate the characteristics of procedures for management and treatment in patients with fibrosing ILD other than IPF in real-world setting in Japan.

Aim of investigators was to study whether abnormalities of lung diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO) in long COVID may have a clinical impact in relation to exercise intolerance.

The study is to assess patient satisfaction with the inhaler attributes of the re-usable Respimat SMI (Spiriva, Striverdi or Spiolto) in patients with COPD, including patients who are Respimat SMI-experienced and Respimat SMI-naïve. This study also aims to examine patient preference for the re-usable Respimat SMI compared to the disposable Respimat SMI in Respimat SMI-experienced patients switching from a disposable to a re-usable Respimat SMI product at study entry.

Chronic obstructive pulmonary disease and periodontitis are chronic inflammatory diseases. The study aims to determine if the genetic polymorphism of SERPINA1 gene in patients with COPD serve as a risk factor for developing periodontitis.

Patients with chronic obstructive pulmonary disease suffer from significant cardiovascular morbidity and mortality. This study wants to determine whether chronic obstructive pulmonary disease might be a risk factor for coronary atherosclerosis and other cardiac markers independent of conventional cardiovascular risk factors. The study is designed as a retrospective matched case-control study with follow-up via telephone interview.

In patients with Interstitial lung diseases (ILD) dyspnea is the most often symptom. Pulmonary lung function tests often do not Show the dyspnea. Aim of the study is to evaluate cardiopulmonary exercise testing concerning therapeutic Monitoring in ILD.

Patients suffering from chronic obstructive pulmonary disease (COPD) commonly get exacerbations of their illness which have many potential triggers including infection. The most common cause of lung infection/pneumonia is an organism named Streptococcus pneumoniae. In Ireland a 13-valent pneumococcal conjugated vaccine (PCV-13) was recently introduced into the childhood vaccination programme. This study aims to investigate the carriage rate of S. pneumoniae in COPD patients over one year and to determine if isolates of S. pneumoniae found within the COPD population would be covered by the PCV-13 vaccine.

A multicenter, multinational, prospective study to clarify, whether the addition of cryobiopsy can avoid surgical lung biopsy in a clinically relevant proportion of patients with suspected Idiopathic Interstitial Pneumonia
