Active clinical trials for "Lung Diseases, Interstitial"

The purpose of this study is to compare AI performance to doctor's performance in the evaluation of IPF/UIP and ILDs without UIP(proven by biopsy).

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.

Nanoparticles (NP) are particles whose length, width and height are less than 100 nanometres. Over the past decade, industrial applications of NP have increased dramatically. Despite their widespread use, their true impact on human health remains unknown and poorly studied. NP exposure in humans primarily occurs via inhalation through the respiratory system. The aim of this study is to estimate the relationships between the nanoparticle load in the lung and bronchi and some interstitial lung diseases. In the aftermath of human exposure to asbestos, the pathological consequences of environmental exposure to nanomaterials could be evaluated upon a mineralogical analysis of pulmonary samples.

The investigators will evaluate the prevalence of lung cancer associated with interstitial lung disease (ILD) and idiopathic pulmonary fibrosis (IPF) utilizing the Korean Health Insurance Review and Assessment Service (HIRA) database, spanning the period from January 2011 to December 2011. The database (HIRA-NPS-2011-0001) was based on random sampling of outpatients from whole population. Patients with ILDs, IPF, connective tissue disorder (CTD), and COPD were identified based on the International Classification of Disease-10 (ICD-10) diagnostic codes.

This is a study that seeks to characterize data obtained from patients with a variety of lung diseases using ultrasound signals obtained from the lung tissue. A standard ultrasound instrument in the doppler mode (not the imaging mode used in examination of pregnant women for instance) is placed on the chest wall and the unique software the investigators have developed analyzes the signal reflected back from within the lung. On the basis of pilot studies performed previously the investigators expect to receive different signals from different diseases. The investigators seek to further characterize these signals to enable accurate diagnosis of different lung diseases using our technology.

The purpose of this study is to identify factors that contribute to higher mortality rates among blacks and Hispanics with diffuse parenchymal lung disease.

The presence of an abnormally increased pulmonary blood pressure worsens the prognosis of patients with interstitial pulmonary disease. The aim of this study is to estimate the frequency of an increased blood pressure in the lungs among patient with interstitial pulmonary disease, and to evaluate the use of different biomarkers in diagnosis of the condition.

In the present study inflammatory mediators will be isolated in induced sputum and exhaled breath condensate and will be correlated with particulate matter measured in these samples.Particulate matter will be assessed by partcle size distribution method and shape analysis. The aim of the study is to perform biological monitoring in environmental and occupational diseases in a non invassive fashion.

The primary objective for this trial is to investigate the incidence probability of progression to Progressive Fibrosing Interstitial Lung Diseases (PF-ILDs) in patients with fibrosing ILD other than Idiopathic Pulmonary Fibrosis (IPF) in real-world setting in Japan. The secondary objective is to investigate the characteristics of procedures for management and treatment in patients with fibrosing ILD other than IPF in real-world setting in Japan.

In patients with Interstitial lung diseases (ILD) dyspnea is the most often symptom. Pulmonary lung function tests often do not Show the dyspnea. Aim of the study is to evaluate cardiopulmonary exercise testing concerning therapeutic Monitoring in ILD.
