Active clinical trials for "Lung Diseases, Interstitial"

Interstitial lung diseases (ILDs) are a heterogeneous group of disorders, which encompass a wide range of conditions. In some patients with fibrosing ILDs, a progressive phenotype similar to that observed in idiopathic pulmonary fibrosis (IPF) may develop during the course of the disease (PF-ILD), including patients with systemic sclerosis (SSc)-related ILD. The aim of the study is to estimate the incidence and prevalence and to describe the characteristics of patients diagnosed with non-IPF PF-ILD and SSc-ILD, to describe the natural course of disease, and to explore the correlation between mortality and Forced Vital Capacity (FVC) of the patients with non-IPF PF-ILD. This study will be based on two data sources: the French national medico administrative database (SNDS) and the ILD cohort from the National French center for rare pulmonary diseases in Lyon, France.

Interstitial lung diseases (ILD) represent a frequent complication of connective tissue diseases (CTDs), especially systemic sclerosis, idiopathic inflammatory myopathies and rheumatoid arthritis. ILD can either occur during CTD course or be the first manifestation of CTDs. Therefore screening patients with ILD for CTD is crucial. In some cases, ILD are associated with clinical and/or serological autoimmune features but not classifiable for CTDs. Evolution of these forms to defined CTDs has never been study. Recently, the European Respiratory Society/American Thoracic Society experts proposed a new term, "interstitial pneumonia with autoimmune features" or IPAF, to describe these patients according to updated classification criteria. Aims of this study were to compare CTD occurence during follow-up between IPAF and non-IPAF patients in a idiopathic interstitial pneumonia cohort and to identify risk factors of CTD progression in IPAF patients at diagnosis.

The purpose of this study is to determine how interstitial lung disease can be predicted over time in early rheumatoid arthritis. The investigators will study blood and phlegm samples from participants, along with quality of life questionnaires to determine if and how the presence of ILD may impact the participants quality of life over time.

The aim of our study is to investigate the etiological distribution of ILD, epidemiological characteristics of ILD cases such as age, gender, geography, smoking, occupation, economic status, education, and comorbidities. Another aim is to make the cost calculation from the first to the diagnosis in the patients diagnosed. Obtaining the missing data related to the ILD of our country is one of our goals.

Scarring of the lungs is common in patients with scleroderma and is one of the main causes of death. Patients with scleroderma very frequently have problems with their gullet (esophagus), the food pipe that leads into the stomach. Normally, a small circular muscle at the base of the esophagus opens to allow food to pass into the stomach and closes to keep the digestive fluids from flowing back up into the gullet. In patients with scleroderma, the muscle may become weak and no longer close properly. Gastroesophageal reflux (GER) is the medical term for reflux of stomach contents into the esophagus. Our hypothesis is that small amounts of GER can move back up into the esophagus and get inhaled into the lungs, and may be one of the triggers for lung scarring. We propose to look for certain substances normally only found in the stomach in the "exhaled breath condensate" which is collected by breathing comfortably into a cooled cylinder, allowing the breath to condensate. In a smaller group of patients, we also plan to perform a bronchoalveolar lavage, a more widely studied test in which a small amount of fluid is introduced into a small part of the lungs through a fine tube, and then removed for examination, to evaluate whether the two tests provide similar measurements. We will also evaluate the correlation between these molecules and other tests, including lung function, and markers of lung scarring activity, and tests to look at how the esophagus is working so that we can get a clearer picture of how this affects patients' daily lives. Finally, we will be following up patients over time with lung function to see whether evidence of GER into the lungs is linked with a greater likelihood of worsening of lung scarring in the future.

Evaluating an integrated diagnostic work-up of virtual navigation bronchoscopy (VNB), confocal laser endomicroscopy and micro computerized tomography (micro-CT) in the diagnostic path of pulmonary lesions in the non-oncological patient.

We hypothesized that the multi-disciplinary assessment of interstitial lung disease patients would lead to a more accurate diagnosis and consequently alterations in treatment regimens that may lead to improved outcomes.

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 hallmark of the L phenotype is the vasoplegia, as confirmed by the rapid change in density and distribution of CT findings from the supine to the prone position. The benefit of a prone position in awake, nonintubated, spontaneously breathing Covid-19 patients has been emerging as potential tool to improve oxygenation and to prevent the access to ICU. No evidence of radiological modifications related to Aim of our study is to evaluate CT changes in terms of extension, distribution and prevalence of findings, in the supine compared with the prone position.
