Active clinical trials for "Lung Diseases, Interstitial"

The Pulmonary Fibrosis Foundation Patient Registry will collect data on at least 2,000 patients with interstitial lung disease (ILD) at approximately 40 clinical sites in the US. The Registry is targeting enrollment of approximately 60% of the 2,000 ILD participants to have idiopathic pulmonary fibrosis (IPF). The aim of the Registry is to create a cohort of well-characterized patients with interstitial lung disease (ILD) for participation in retrospective and prospective research

Pulmonary hypertension (PH) is a common disorder among patients with interstitial lung disease (ILD). The symptoms are usually nonspecific and overlooked. Thus, a noninvasive screening modality is recommended for early detection of PH because of its potentially significant impact on treatment strategy and clinical outcomes. Objectives: To evaluate the usefulness of assessing forced vital capacity (FVC%), diffusion capacity of the lung for carbon monoxide (DLCO%), and FVC%/DLCO% ratio to predict pulmonary hypertension among patients with ILDs.

The objective of this study is to administer and validate a disease specific health related quality of life (HRQOL) survey for patients with Chronic Hypersensitivity Pneumonitis (CHP).

The recent pandemic due to the SARS-CoV2 results in a pulmonary infection in major symptomatic patients. Because of the large number of patients and the risk of acute respiratory distress syndrome (which seems to occur in almost 5% of patients), there is a real challenge to improve physician ability to screen between patients those who will require specific surveillance and those who can be sent back home. The recent French official recommendation of the French radiology society prescribe that chest X-ray do not have any place in the COVID-19+ management whereas the WHO stipulate that ultrasound machines may be useful for these patients [1-2]. Moreover, scattered recent publications tend to stress the interest of quick ultrasound imaging for COVID-19 suspected patients for screening purpose [2-5]. The aim of this observational historico-prospective study is to assess the risk of severe clinical outcomes (admission in continuous care unit (USC), invasive respiratory assistance, death) in patients suspected or diagnosed COVID-19+ as a function of initial pulmonary ultrasound abnormalities. These clinical outcomes are assessed through phone calls at D5, D15, M1. The secondary objectives are: Assessing the concordance between the severity of pulmonary lesions as detected by pulmonary ultrasound devices and the ones detected by CT-scanner, for patients who will undergo these two examinations. Assessing the compared performances in detecting ultrasound pulmonary lesions for patients suspected or diagnosed COVID-19+, between an experimented operator and a newly trained operator. Evaluate in suspected or COVID-19 patients, the risk of clinical worsening based on pulmonary ultrasound abnormalities during follow-up of hospitalized patients. Evaluate the ultrasound evolution profiles of pulmonary lesions in patients whose clinical evolution is favorable. Evaluate the incidence of thromboembolic events in patients who worsen secondarily.

Diffuse interstitial lung disease brings together a heterogeneous group of pulmonary pathologies, characterized by infiltrating and diffuse lesions of the pulmonary interstitium. The evolving risk of these ILD is pulmonary fibrosis, with the development of chronic respiratory failure. The process of the etiological diagnosis of ILD results from a multidisciplinary approach (pulmonologists, radiologists, occupational health specialists, anatomo-pathologists, etc…). Indeed, the multitude of possible causes of these diseases makes the etiological diagnosis difficult. Professional aetiologies are also frequently mentioned : pneumoconiosis, hypersensitivity pneumonitis, as a differential diagnosis. It therefore appears essential to deepen the professional aspect during the diagnostic process for ILD. Since May 2020, a professional interview has been systematically offered by the Occupational Pathology Consultation Center of the Hospital Center Lyon Sud, to patients followed by the team of Professor Vincent COTTIN, whose file was discussed in a multidisciplinary meeting. The data collected to constitute a database are the following variables: age, sex, diploma, professional course coded in CITP (International Standard Classification of Professions) and NAF (French Nomenclature of Activities), occupational exposures, smoking, risk factors non-professionals, clinical elements of ILD and elements relating to an occupational disease certificate. This database is anonymized.

To determine risk factors for idiopathic pulmonary fibrosis.

To investigate the ability of machine learning models based on radiomic features extracted from thin-section CT images to differentiate IPF patients from non-IPF interstitial lung diseases.

In the late 2019 a new Coronavirus was identified as the cause of a group of atypical interstitial pneumonia cases in Wuhan, a city in the Chinese province of Hubei. In February 2020, the World Health Organization designated COVID-19 disease, which stands for Coronavirus 2019 disease. Following the progressive spread of the infection in other countries of the world, WHO declared the Pandemic on 11 March 2020. Italy was the first European country involved in the spread of the infection and among those with the highest number of victims. The Coronavirus responsible for COVID-19 has, as its main target organ, the respiratory system, being able to determine a serious acute respiratory syndrome similar to that of the cases found during the SARS epidemic of 2003: hence the name of the virus as SARS-CoV-2. The diagnosis of SARS-COV-2 infection is made by direct detection by PCR of viral RNA on different biological materials from patients with suspicious symptoms, and the first level diagnostic test is generally the nasopharyngeal swab. However, even if the specificity of the nasopharyngeal swab is high, its sensitivity can be affected by technical causes (sampling mode), as well as by intrinsic factors related to the method. The purpose of the study is to identify the clinical, laboratory and imaging characteristic which are similar or which can differentiate the hospitalized patients affected by COVID-19 pneumonia (with positive PCR on naso-pharyngeal swab) and patients with pneumonia with negative PCR for COVID-19. To do this, the investigators will compare the clinical, laboratory and imaging characteristics between interstitial pneumonia secondary to SARS-COV-2 infection, confirmed by molecular biology investigations (viral RNA research by PCR on nasopharyngeal swab) and cases of interstitial pneumonia negative to the nasopharyngeal swab.

Drug induced interstitial lung disease (DIILD) is caused by iatrogenic injury to the lung parenchyma and can be caused by over four hundred different drugs in humans. Diagnosing DIILD is a challenge for clinicians and radiologists as a positive diagnosis depends on exclusion of other causes including respiratory infection, occupational, recreational, and environmental exposures, specific respiratory disorders, and systemic diseases. The aim of this study is to qualify an objective CT scoring system for DIILD assessment. In addition, the quantitative information obtained from CT scans with densitometry and texture analysis will be explored.

Background: Pulmonary diseases are significant contributors to morbidity and mortality in patients with rheumatoid arthritis (RA). One of the most common pulmonary manifestation in RA is interstitial lung disease (RA-ILD). Consequently, RA-ILD may be prevalent in approximately 30% and clinically evident in about 10% of RA patients. Since the median survival for patients with manifest RA-ILD is only 6.6 years, feasible methods of detecting early RA-ILD are warranted. Objectives: To determine the diagnostic accuracy of thoracic ultrasound (TUS), using a 14-zone protocol, for ILD in RA patients with respiratory symptoms by using chest high-resolution computed tomography (HRCT) as the reference standard. The secondary aim is to evaluate the diagnostic accuracy for the blood biomarkers surfactant protein-D (SP-D) and microfibrillar-associated protein 4 (MFAP4) in the detection of ILD in this group of patients. Data collection: Participants will be included after signing the informed consent; data will be collected and stored in a REDCap database. Eligibility criteria for participants and settings where data will be collected: Patients eligible for inclusion are consenting adults (≥18 years) diagnosed with RA (according to the 2010 ACR-criteria for RA) and respiratory symptoms indicating RA-ILD, based on the presence of at least one of the following symptoms: unexplained dyspnoea, unexplained cough and/or a residual pneumonia or a chest X-ray indicating interstitial abnormalities in the lung. Whether participants form a consecutive, random or convenience series: Participants form a consecutive series of up to 80 individuals in total. Description of the index test and reference standard: Patients suspected of having RA-ILD will undergo a 14 zone TUS as index test performed by a junior resident in rheumatology, who is certified by the European Respiratory Society in performing TUS assessment. The anonymised images will be stored, and scored by the junior resident and two senior rheumatologists, who have also received training in TUS, as well as a TUS and ILD experienced pulmonologist. Chest HRCT will be the gold standard, i.e. the ILD reference standard. Estimates of diagnostic accuracy and their precision: The two basic measures for quantifying the diagnostic accuracy of the TUS (index) test are the sensitivity and specificity in comparison to the chest HRCT. Statistical tests will be conducted using the McNemar test for correlated proportions.
