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

The identification of bronchiectasis in COPD has been defined as a different clinical COPD phenotype with greater symptomatic severity, more frequent chronic bronchial infection and exacerbations, and poor prognosis. A causal association has not yet been proven, but it is biologically plausible that COPD, and particularly the infective and exacerbator COPD phenotypes, could be the cause of bronchiectasis without any other known etiology, beyond any mere association or comorbidity.

The investigators intend to explore the characteristics and outcomes of pregnant women with PAH during different pregnancies and to provide applicable evidence for clinical practice.

This is an observational study of recording the respiratory parameters of patients when receiving non-invasive ventilation and analyze the relationship between those parameters and clinical outcomes.

The objective of the investigator's study is to detect the characteristics, pattern and outcome of pulmonary tuberculosis patients treated at Assiut University Hospital by collecting their demographic, clinical, laboratory and radiological data.

The main objective of this study is to describe the incidence of thromboembolic events in a population of patients hospitalized in intensive care units in France for severe COVID-19. The secondary objective of this study is to describe the evolution of hemostasis parameters during the first two weeks of intensive care hospitalization and to evaluate the influence of different anticoagulation regimens on these parameters and on the incidence of thromboembolic events

Renal damage in patients hospitalized for ARDS in the ICU can also be related to multiple causes including, but not limited to, the consequences of hemodynamic fluctuations in these patients or the use of nephrotoxic drugs responsible for acute post-ischemic or toxic tubular necrosis. Frequently observed abnormalities of cioagumation may also have a potential impact on renal structures, particularly glomerular capillaries. The researchers wish to characterize and phenotype the renal impairment of patients hospitalized in intensive care with tables of severe Covid19 infections in ARDS: clinical, biological and histological (by performing post-mortem biopsies).

The investigators investigate the utility of FDG PET/CT based radiomics in lung cancer, including diagnosis and prognosis.

The purpose of this study is to evaluate the potential correlation of the results of allergen-specific skin prick tests (SPT) to that of allergen-specific microarray determination (microassay test). Subjects who meet enrollment criteria, after signing an IRB approved consent form, will perform a minor finger prick blood draw and blot to be mailed off for microassay analysis. Specific statistical analysis will be done to assess all potential correlations between SPT and microassay. This study design should enable assessment of the level of correlation between SPT results and microassay results for specified allergens within a cohort of subjects with allergic rhinitis.

This study will investigate the changes in the reflux symptom index (RSI) and reflux finding score (RFS) among patients with obstructive sleep apnea after regular humidified CPAP therapy. Since these two diseases have strong associations then one may consider the possible benefits from therapy in between them.

The investigators intend to evaluate the function of left heart and right heart and the motion balance between four chambers of the heart by speckle tracking technique during the follow-up of patients with pulmonary hypertension, and explore the relationship between the balance and prognosis of patients.
