Active clinical trials for "Lung Diseases"

This study is designed as a prospective study, with the primary endpoint being changes in pulmonary hemodynamic parameters after ELVR in patients with severe emphysema. Secondary endpoints will be changes in lung function parameters, exercise capacity, and QoL.

Current diagnostic tools used in interstitial lung disease (ILD) do not meet the challenges set by the complex pathophysiology of this heterogenous group. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various ILDs.

The ongoing pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2) has infected more than one hundred twenty million peoples worldwide one year after its onset with a case-fatality rate of almost 2%. The disease due to the coronavirus 2019 (i.e., COVID-19) is associated with a wide range of clinical symptoms. As the primary site of viral invasion is the upper respiratory airways, lung infection is the most common complication. Most infected patients are asymptomatic or experience mild or moderate form of the disease (80 %). A lower proportion (15%) develop severe pneumonia with variable level of hypoxia that may required hospitalization for oxygen therapy. In the most severe cases (5%), patients evolve towards critical illness with organ failure such as the acute respiratory distress syndrome (ARDS). At this stage, invasive mechanical ventilation is required in almost 70 % and the hospital mortality rises to 37 %. Immune cells are key players during SARS CoV-2 infection and several alterations have been reported including lymphocytes (T, B and NK) and monocytes depletion, and cells exhaustion. Such alterations were much more pronounced in patients with the most severe form of the disease. Beside, a dysregulated proinflammatory response has also been pointed out as a potential mechanism of lung damage. Finally, COVID-19 is associated with an unexpectedly high incidence of thrombosis which probably results from the viral invasion of endothelial cells. The investigators aim to explore prospectively the alterations of innate and adaptive immune cells during both the acute and the recovery phase of SARS CoV-2 pneumonia. Flow and Spectral cytometry will be used to perform deep subset profiling focusing on T, B, NK, NKT, gamma-gelta T, monocytes and dendritic cells. Each specific cell type will be further characterized using markers of activation/inhibition, maturation/differenciation and senescence as well as chemokines receptors. T-cell memory specificity will be explore using specific SARS CoV-2 pentamer. Platelet activation and circulating microparticles will be explore using flow cytometry. Serum SARS CoV-2 antibodies (IgA, IgM, IgG), serum cytokines, and serum biomarkers of alveolar epithelial and endothelial cells will be analyze using ELISA and correlate with the severity of the disease.

The main objective is to describe the phenotypic features of the paediatric and adult patients with Idiopathic Interstitial Pneumopathy/Pneumopathy Interstitial Diffuse (IIP/PID), at diagnosis and during the follow-up. These data will be critical for the description of the natural history of the various forms of IIP/PID.

The study looked at whether regular physical activity can influence sleep duration, sleep quality and/or anxiety in patients with chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). The link between exercise and sleep has already been observed in the literature, but the impact of exercise on sleep is poorly understood. The question is how important is the influence of regular physical activity on sleep, anxiety and depression in patients with COPD or IPF.

Right thoracotomy, conventional approach to esophageal atresia repair, leads to up to 60% radiological chest wall sequelae anomalies. The impact of these anomalies on the patient's respiratory function remains unknown. Minimally invasive thoracic surgery considerably reduces this rate. The primary objective of this study is to assess the occurrence of restrictive lung disease in patients with type III esophageal atresia depending on the type of surgical approach (Conventional or minimally invasive). The primary endpoint will be he occurrence of restrictive lung disease , objectified by pulmonary function tests (PFTs), carried out according to the current national guidelines (PNDS = protocole national de diagnostic et de soins).

Aim: To investigate whether ER stress is implicated in the pathogenesis of various pulmonary disorders Measurement: Unfolded protein responses (UPRs) in blood (PBMCs)of patients CHOP GRP 78 and so on Unfolded protein responses (UPRs) in blood (PBMCs)of healthy controls CHOP GRP 78 and so on

The objective of this work is to investigate and then to sequence new biomarkers in the plasma of patients presenting with dyspnea secondary or not to heart failure, and study their diagnostic and prognostic value.

A biobank of Serum, plasma, DNA samples together with clinical information including specific questionnaires, complete pulmonary function and chest CT-scan, is prospectively collected in patients seen at the investigators' clinical service. The objective is to study candidate gene pathways in COPD and or lung cancer and to associate them with the clinical characteristics and phenotypes of COPD/emphysema and lung cancer. In subgroups of well characterised patients, other biological materials are also collected (lung tissue biopsies, peripheral blood mononuclear cells).

The cause of most interstitial lung diseases (ILDs) is still unknown. Further research, for example to determine predisposing genetic factors, is therefore needed. A database with relevant clinical data and DNA/serum samples of ILD patients could facilitate future research on the cause of ILDs.
