Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

COVID-19 infection manifests in its severe form as acute alveolo-interstitial and vascular pneumonitis. However, long-term outcome remains unknown. A progression to fibrosing pneumonia could affect 10 to 30% of survivors of severe forms, making it a public health problem through secondary disability. The project concerns the analysis of CT images of patients followed at the Avicenne APHP hospital (Bobigny) in collaboration with two expert image treatment/modelling teams for an evaluation of vascular remodelling and mechanical simulation of the regional lung compliance. These parameters obtained at 2-4 months of COVID-19 infection will be correlated with clinical, CT, and functional data at 6 months and 1 year follow-up. This project should make it possible to understand the COVID-19 infection manifests as an acute alveolo-interstitial and vascular pneumonitis in its severe form. However, long-term outcome remains unknown. It has been hypothesized that a progression to fibrosing pneumonia could affect 10 to 30% of survivors of severe forms, making it a public health problem through secondary disability. But there is no parameter which could currently allow to predict such an outcome. The SILICOVILUNG project is based on the CT images analysis of patients followed at the Avicenne APHP hospital (Bobigny, France) after severe COVID pneumonitis in collaboration with two expert image treatment/modelling teams [ Artemis Telecom Sud-Paris (Evry, France) and LMS INRIA Ecole Polytechnique (Palaiseau, France)] for an evaluation of vascular remodeling and mechanical simulation of the regional lung compliance using a poromechanical model. These parameters obtained at 2-4 months of COVID-19 infection will be correlated with clinical, CT, and functional data at 6 months and 1-year follow-up. This project should make it possible to understand the mechanisms of regional physiology in the evolution of COVID-19 pneumonias in their severe forms and to anticipate the development or not of sequelae, particularly fibrosing.

The aim of this study is to evaluate the diagnostic value of sputum cell counts in differentiation between asthma, COPD and ACO. to examine the relationship between sputum cell counts in bronchial revers¬ibility and bronchial hyperresponsiveness

This observational Mycobacterium tuberculosis (MTB) diagnostics evaluation study is a prospective study of pulmonary TB suspects who are undergoing sputum or bronchoalveolar lavage fluid (BALF) evaluation for pulmonary TB. The sensitivity and specificity of the CRISPR-based assay will be compared to clinical diagnosis, conventional culture methods and Xpert MTB/RIF assay on same batch specimens.

A prospective multi-centre, non-interventional observational study, that will be conducted in several centers in Greece for a 2-year time period (completion date December 2020), to describe patient characteristics, medical history, and the clinical benefit of mepolizumab in patients with severe eosinophilic asthma newly initiated to the drug.

To define the potential role of pleural fluid attenuation value determined on computed tomography (CT) for diagnosis of traumatic hemothorax and differentiate it from other pleural effusion.

The VRS (Respiratory Syncytial Virus) study group in Lyon is a working that aims to understand, predict and prevent the burden of disease caused by human respiratory syncytial virus (RSV) infection in infants. Incidence of RSV-associated hospitalization in the first year of life was estimated at 14.5 (95% CI 13.4-15.6) per 1000 births in a cohort study in Lyon, France. Related direct medical annual costs were estimated for this cohort at 364,269€, mostly attributed to children born during the RSV season (231,959€) and children born premature (108,673€). This study will combine existing hospital specimens and databases to determine the respective role of socio demographic factors, clinical risk factors, level of cord specific antibody at birth, and virus characteristic in the Respiratory Syncytial Virus (RSV) Hospitalization outcome in Infants. Regarding the introduction of a new RSV vaccine and RSV-specific neutralizing antibodies, these data are of prime importance to guide future vaccine policies.

Premature neonates are prone to respiratory distress and need ventilator support because of the rapid breathing and large variations in respiratory patterns. The setting and adjustment of the ventilator for premature neonate is not easy, often resulting in poor patient-ventilator interaction, increased work of breathing, patient discomfort and delayed weaning . Recently, a new ventilation mode (NAVA; Neurally Adjusted Ventilatory Assist) mode, allows the respirator to provide a proportional ventilation mode based on the patients' diaphragm electrical activity, which was validated in many domestic and international clinical researches. The NAVA mode improves patient-ventilator interaction, reduces work of breathing and contributes to early weaning and extubation . When participating in this study, the neonate with receive a special oral tube placement, which is used to replace the original gastric tube to monitor the electrical activity of the diaphragm.

It's based in an observational trial in mechanical ventilated patients. The investigators assess the head of bed elevation angle in the routine treatment of the unit. The investigators decide to assess the time the patient has a semirecumbent position >35°.

Coronavirus disease 2019 (COVID-19) is a serious respiratory disease that results from infection with a newly discovered coronavirus (SARS-COV-2). Unfortunately, COVID-19 is not only a short-term infection. Patients (pts) recovering from SARS-COV2 infection complain of persisting symptoms including: fatigue, diffuse myalgia and weakness, which may lead to chronic fatigue syndrome and as well as many other complications. The vast majority of COVID-19 patients remaining in isolation/quarantine, due to the mild course of the disease, do not require hospitalization. In this group of patients, the course of COVID-19 is very different - from asymptomatic patients to very severe and long lasting symptoms also with a decrease in saturation. There are many studies describing the course and complications of patients hospitalized due to COVID-19. There is little published data on how non-hospitalized patients get sick and what are the early and late complications of SARS-CoV-2 infection. In addition, many patients remain ill even many months after COVID-19, entering what is known as LONG-COVID. Therefore, the STOP-COVID Registry was established. The purpose of the Registry is to assess the course of COVID-19 infection, early and late cardiovascular complications of COVID-19 in patients with and without hospitalization. In addition, the purpose of the STOP-COVID Registry is to assess the incidence of LONG-COVID with all other complications and to identify predictive factors.

Hypoxemic acute respiratory failure is one of the main COVID-19 patients complication that lead to in intensive care hospitalization. This complication determines a variable mortality from 25 to 30%. To correct hypoxemia (often severe) is often needed non-invasive or invasive mechanical ventilation. Mechanical ventilation is not a therapeutic strategy, but it allows to extend the time-to-recovery necessary to solve COVID-19 respiratory failure cause. Calibration of ventilatory support is essential to ensure adequate time-to-recovery without contributing to onset lung and / or diaphragmatic damage. Basal diaphragmatic activity assessment, device for administering the oxygenation support choice and setting ventilatory support parameters are decisive. Ultrasound is the best method for measuring diaphragmatic work. The aim of this study is to evaluate the diaphragmatic thickening fraction in COVID-19 patients admitted to Intensive Care Unit (ICU) for acute respiratory failure and to record its function on weaning.
