Active clinical trials for "Lung Diseases, Interstitial"

Interstitial lung disease (ILD) is a restrictive lung disease characterized by impaired lung function, exercise limitation and skeletal muscle dysfunction. There is limited data on skeletal muscle function in ILD, most of which are focused on the lower limb muscles. The aim of this study were to evaluated the change of pectoralis muscle strength and relationship of pulmonary function with pectoralis muscle strength.

Interstitial lung disease is a devastating lung condition with terrible outcomes. Lung cancer is the world's leading cause of cancer related death. Unlike breast and bowel cancer, there is no lung cancer screening programme in the UK. However, there are a number of pilot lung cancer screening programmes taking place including one in Manchester. The CT scans used in lung cancer screening programmes pick up other lung conditions out with lung cancer, including interstitial lung disease. This provides a unique opportunity to diagnose interstitial lung disease at an early and non-symptomatic stage where treatment can be initiated early to halt progression of disease and development of symptoms. The investigators aim to determine how much (prevalence) interstitial lung disease can be picked up in a lung cancer screening programme and how these cases would compare to those diagnosed with interstitial lung disease through the 'standard' way in the clinics. The investigators hypothesis that the patients diagnosed through the screening programmes will have an earlier stage of disease with less symptoms. If this is to be the case, this would provide researchers with the opportunity to diagnose interstitial lung disease through lung cancer screening programmes and initiate treatment early.

This study uses a new breathing device called 'N-Tidal C' handset which measures breathing patterns. Investigators have found that people with cardiac and respiratory illnesses breathe out a gas, called carbon dioxide (CO2), in a different way to healthy people. The pattern of breathed out CO2 (the waveform) varies according to the underlying health of the user's lungs. Monitoring these changes may help doctors to more accurately diagnose and monitor the most common and serious respiratory conditions.

Pneumonia is a recurrent element of COVID-19 infection, it is often associated with development of respiratory failure and patients frequently need various degrees of oxygen therapy up to non invasive ventilation (NIV-CPAP) and invasive mechanical ventilation (IMV). Main purpose of this study is to evaluate with non invasive clinical instruments (pletysmography, Diffusion lung capacity for carbon monoxide -DLCO-, six minute walking test and dyspnea scores) and radiological tools (chest X-ray and chest CT scan) the development of medium-to-long term pulmonary sequelae caused by SARS-CoV-2 pneumonia.

Interstitial lung disease (ILD) often affects distal lung, and the evaluation of drug distribution to the relevant lung compartments is essential for development of new treatment options. This single center study will utilize samples obtained by transbronchial cryobiopsy (TBCB) procedure to assess the distribution of inhaled drugs in the lungs of the subjects with fibrotic lung disease using mass spectrometry techniques. The study will have a single visit and will include approximately 20 adult subjects with suspected fibrotic ILD and requiring TBCB as part of their diagnostic assessment. This will provide TBCB samples from up to 20 subjects, up to 5 of whom may also provide endobronchial forceps biopsy samples. The study will have 3 phases including screening to check the eligibility, biopsy phase in which all subjects will receive nebulized ipratropium bromide 500 microgram (mcg) for 10 minutes immediately before undergoing bronchoscopy and follow up phase from 7 to 14 days after the procedure. Drug distribution in the lung will be assessed by analyzing biopsy samples collected using mass spectrometry and imaging techniques.

The investigators will investigate the interrelationship of macrophage migration inhibitory factor (MIF) and free T4 in patients with PAH.

The diagnosis of idiopathic interstitial pneumonia (IIP) is based on computed tomography (CT) imaging, whereas lung function studies are used for staging and follow up. Lung diffusing capacity for carbon monoxide (DLCO) is generally reduced but weakly correlated with the severity of CT-determined fibrotic process. A possible explanation of this finding is that DLCO is relatively insensitive to changes in alveolar membrane diffusive conductance (DMCO). Lung diffusion capacity for nitric oxide (DLNO) was strongly correlated with CT-determined amount of fibrosis/honeycombing in both usual and non-specific interstitial pneumonias. Moreover. Both DLNO and DMCO were below the lower limit of normality even in patients with small amount of fibrosis. Measurement of DLNO may provide a more reliable assessment of fibrotic changes than DLCO because it better reflects DMCO.

HYPID-2 study is an extension of HYPID study (NCT01443598) : HYPID-2 is also an observational and prospective study of patients with interstitial lung disease and pre capillary hypertension diagnosed by right heart sided catheterization. It concerns only incident patients (i.e patients included within 6 months after PH diagnosis) whereas HYPID concerned prevalent and incident cases. The primary aim is the same than HYPID : identify prognostic factors

The purpose of this study is to evaluate the clinical utility of specific autoantibody testing in unmasking an underlying connective tissue disorder in patients who present with interstitial lung disease and found to have weak positive ANA (1:400 titre) with no overt connective tissue disease manifestations OR borderline/negative ANA with some clinical suggestion of connective tissue disease.

This is a research study where researchers are collecting blood to evaluate the genetic characteristics of individuals with chronic lung diseases, including asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, cystic fibrosis, and lung cancer.
