Active clinical trials for "Lung Diseases"

This study will evaluate the link between blood group antigens and asthma exacerbations.

The purpose of this study is to evaluate with sufficient precision and according to gender the determining independent factors of quality of life related to respiratory status of patient with moderate to severe COPD.

The study aim is to verify the association between the changes in markers of disease and patient´s prognosis in chronic obstructive pulmonary disease.

Under daily routine conditions and without any intervention by the sponsor regarding the selection of subjects, diagnostic procedures, therapeutic decisions (medicinal and non- medicinal therapy, dose, duration, etc.), routine assessments, the participating physicians (i.e. pneumologists and internists) are asked to document relevant data related to the budesonide/formoterole therapy in patients with COPD.

Interstitial lung diseases (ILD) in children represent a heterogeneous group of rare and not well defined disorders. Genetic abnormalities of surfactant proteins B (SFTPB) and more recently C (SFTPC) have been shown to be related to these pathologies. However, variability in the lung disease phenotype suggests the involvement of other surfactant-associated genes such as ABCA3 (ATP-binding cassette, sub-family A, member, 3). Thus, the aim of this project is: 1) to assess the prevalence of SFTPC mutation in children with chronic lung diseases, 2) to precise clinical and radiological features of children with SFTPC mutation, and 3) to identify environmental or genetic factors that may explain the extreme variability of this disease.

We hypothesize that hypoxia-induced pulmonary vascular remodeling is mediated by macrophage migration inhibitory factor (MIF), that remodeling is in fact the reflection of a chronic inflammatory process, and that MIF may be a useful biomarker of the severity and progression of both ILD and PH.

This study aimed to assess airway inflammation in patients during the course of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) by serial analyses of their exhaled breath condensates (EBC).

Fibered confocal fluorescence microscopy (FCFM), also referred to as Cell-Vizio® (MaunaKea Technologies, France) is a new technique that produces microscopic imaging in a living tissue, through a 1 mm fiberoptic miniprobe that can be introduced into the working channel of the bronchoscope. The system produces real-time imaging of endogenous fluorophores with a 5 µm lateral resolution and a field of view of 600 x 600 µm. FCFM is able to produce dynamic, high-resolution microimaging of the respiratory bronchiolar walls, alveolar ducts and sacs in vivo during endoscopy (a procedure termed as alveoscopy). The hypothesis of this study is that an alveoscopy makes it possible to analyze the microstructure of the distal airways in vivo and to collect specific morphologic information in patients with interstitial lung diseases. The goals of this French Phase II trial are: to evaluate the tolerance of the alveoscopy to describe the normal appearance of the bronchoalveolar system in spontaneous ventilation in normal subjects to describe specific alterations of the bronchoalveolar microstructure in focal or diffuse interstitial lung diseases

This is a research study where researchers are collecting blood to evaluate the genetic characteristics of individuals with chronic lung diseases, including asthma, COPD (chronic obstructive pulmonary disease), interstitial lung disease, cystic fibrosis, and lung cancer. The investigators hope to be able to identify an association between a genetic make-up in the blood samples and the risks of developing a particular lung disease, or severity of a lung disease. The findings of this study might be important to develop future preventative methods and potential treatments for the management of lung disease.

The first objective of this study is to determine if increased expression of one or more members of the toll-like receptor (TLR) family of receptors that are found on inflammatory cells (present in the airway) precede development of chronic lung disease (CLD) of prematurity. The study will also determine if there is a significant correlation between TLRs and the severity of CLD. The second objective of this study is to determine the impact of c-administration of inhaled nitric oxide (INO) on TLR expression in infants at risk of developing CLD or with early CLD.
