Hyperoxia During Pulmonary Rehabilitation in Chronic Lung Disease - Does it Matter?
Chronic respiratory diseases are a global burden. Treatment options have improved in recent years, pulmonary rehabilitation plays a key role. Oxygen therapy is recommended in patients with a low saturation at rest, but no clear guidance is given for patients who desaturate during exercise. The effect of ambulatory oxygen during exercise is not yet completely understood, especially in those patients with exercise-induced desaturation. Aim: The goal of this study is to analyse the effect of supplemental oxygen given during a constant work rate exercise test (CWRET) on a cycle ergometer compared to sham air. Methods: We plan to...

Hyperpolarized 129-Xenon MRI in Fibrosing Interstitial Lung Disease
This project aims to investigate the potential of non-invasive imaging to identify and monitor the earliest signs and physiological effects of pulmonary fibrosis and resulting cardiac dysfunction in patients with fibrosing interstitial lung disease. Second, to evaluate baseline risk factors the progression and therapeutic responses to anti-fibrotic drugs.

Impact of Mutations in Aminoacyl tRNA Synthetases on Protein Translation and Cellular Stress
Mutations in the genes encoding cytosolic aminoacyl-tRNA synthetases are responsible for early-onset multisystemic diseases including to varying degrees interstitial lung disease, liver damage, neurological and digestive disorders, and systemic inflammation. These are rare and severe diseases whose pathophysiology is poorly understood. The investigative team hypothesizes that mutations within these genes are responsible for a decrease in protein translation and lead to a cellular stress response similar to that induced by amino acid deprivation. The investigative team also hypothesizes that these alterations could be corrected by...

Inspiratory Effort Assessed Through Nasal Pressure Measurement in Patients With Idiopathic Pulmonary Fibrosis
Idiopathic Pulmonary Fibrosis (IPF) is a fibrosing progressive interstitial lung disease with unknown etiology, with a median survival of 3 years since first diagnosis. The typical radiologic pattern of the disease is usual interstitial pneumonia (UIP) defined by basal and peripheral (subpleural) predominance and a typical cystic degeneration of lung parenchyma (honeycombing), interstitial fibrotic thickening and traction bronchiectasis. Despite the recent introduction of two antifibrotic treatments (Pirfenidone and Nintendanib) which proved to be successful in slowing the decline of pulmonary function in patients with IPF, a benefit ...

Investigation of the Efficacy of Metformin Therapy on Pulmonary Sarcoidosis
This is a double blinded, randomized, placebo controlled clinical trial of 40 participants with pulmonary sarcoidosis. Primary Objective: To assess the steroid-sparing efficacy and safety of oral metformin therapy in participants with confirmed progressive pulmonary sarcoidosis for participants with steroid dependent disease.

LetS Get fUnctional! FuNctional Status in pEople With intersTitial Lung Disease
This study aims to i) To characterize the functional status and explore the determinants of functional status decline of people with IlD ii)To determine the measurement properties of functional status instruments in people with Interstitial lung diseases (ILD) iii) To identify the impact of ILD and the participants' perspectives on functional status through interviews iv) Explore the progression of functional status progression in people with ILD and v) Develop a multidimensional index, incorporating functional status parameters, to predict mortality in people with ILD. Patients with ILD will be recruited via the pulmonology...

Londrina Activities of Daily Living Protocol in Idiopathic Pulmonary Fibrosis Patients
The Londrina Activities of Daily Living Protocol was first developed for Chronic Obstructive Pulmonary Disease patients and was found to be valid and reliable, but there is no validity and reliability study of the Londrina Activities of Daily Living Protocol in IPF patients. The purpose of the study is to Examine the Validity and Reliability of the Londrina Activities of Daily Living Protocol in Idiopathic Pulmonary Fibrosis (IPF) patients.

Misdiagnosis Between Interstitial Lung Disease and Cardiac Patients
Aim of the study To determine the frequency misdiagnosis of cardiac congestion as interstitial lung disease based on initial High Resolution CT interpretation alone. To identify specific HRCT findings that are more commonly associated with misdiagnosis versus correct diagnosis of the underlying condition. To establish diagnostic criteria or HRCT patterns that distinguish cardiac congestion from interstitial lung disease

Mycophenolate Mofetil in Systemic Sclerosis With Subclinical Interstitial Lung Disease
The goal of this pilot study is to assess the feasibility of a larger study on the efficacy of mycophenolate mofetil in people diagnosed with systemic sclerosis with mild lung involvement. Participants will be recruited over 12 months at 3 academic centers and assigned randomly to receive either mycophenolate mofetil or placebo, a look-alike substance that contains no active drug, for 96 weeks.

NIV Versus HFO for Acute Exacerbations of Interstitial Lung Diseases
The objectives of this study are to compare the physiological consequences of high-flow oxygen therapy and noninvasive mechanical ventilation on ventilation, respiratory work and hemodynamics during acute respiratory failure in diffuse interstitial pneumonia.
