Lung Transplant READY CF 2: CARING CF Ancillary RCT
Lung transplant is an option for treating end-stage lung disease in cystic fibrosis (CF). In the United States, more people with CF and low lung function die each year than undergo lung transplant. More than half of people with CF who die without a lung transplant were never referred for consideration. Patient preference not to undergo lung transplant may account for 25-40% of decisions to defer referral. Patients' health discussion networks function to support individuals in health related matters and may provide critical support during the lung transplant journey. Increasing awareness of lung transplant, and promoting the process...

Management of Progressive Disease in Idiopathic Pulmonary Fibrosis
Idiopathic pulmonary fibrosis (IPF) is a prototype of chronic, progressive, and fibrotic lung disease. It has been considered rare, with an incidence estimated to 11.5 cases per 100 000 individuals per year. Increasing rates of hospital admissions and deaths due to IPF suggest an increasing burden of disease. The median survival time from diagnosis is 2-4 years. Recently two disease-modifying therapies, pirfenidone and nintedanib, have been approved worldwide. Both drugs reduce the disease progression as measured by progressive decline in forced vital capacity (FVC), with a reduction of overall mortality showed by meta-analysis of ...

Mapping Chemical and Microbiological Heterogeneity Throughout Explanted Cystic Fibrosis Lung Specimens
There is plenty of evidence to suggest that the lung is not uniform. The internal surface area is 30 times that of skin, and the different bronchioles/bronchi/alveoli differ greatly in blood perfusion, temperature, oxygen tension, and pH. Also, particularly in the context of respiratory disease, notable differences are present in the structure of epithelial cells, cilia, production of mucus, and inflammatory/immune responses. All of these factors are known to impact the physiology of bacteria, yet, there is very little understanding of how they impact a) the presence/absence of particular bacterial species throughout the respiratory ...

Mechanisms of Familial Pulmonary Fibrosis
This a prospective, longitudinal study of first-degree family members of patients diagnosed with familial interstitial pneumonia (FIP). FIP is the familial form of idiopathic pulmonary fibrosis (IPF), which is defined as 2 or more bloodline relatives which have a diagnosis of idiopathic interstitial pneumonia (IIP). The most common form of idiopathic interstitial pneumonia in FIP families is IPF (approximately 70%). The inheritance pattern in FIP is consistent with autosomal dominant inheritance with incomplete penetrance. Therefore, individuals in this study have approximately 50% risk of carrying a disease-associated allele. The...

Molecular Diagnosis of Idiopathic Interstitial Pneumonias: a Prospective Study
Molecular diagnosis of idiopathic interstitial pneumonias is an innovative way to potentially improve the diagnostic accuracy of surgical lung biopsies (SLBs), introducing molecular classifiers of idiopathic pulmonary fibrosis (IPF) vs. non-specific interstitial pneumonia (NSIP) vs. chronic hypersensitivity pneumonitis (CHP). The investigators hypothesize that pre-defined gene expression profiles previously identified on large lung explants can still be identified and reproducible on smaller, clinically available surgical lung biopsies (SLBs), and can be used to increase diagnostic accuracy during multi-disciplinary discussion. ...

Molecular Imaging Probes to Inform Heterogeneity in Idiopathic Pulmonary Fibrosis
The purpose of the study is to see if imaging with fluorine-18 Fluorodeoxyglucose ([18F] FDG) and fluorine-18 Displacement Per Atom ([18F]DPA-714) using positron emission tomography and computed tomography (PET/CT) will show lung inflammation and fibrosis in patients diagnosed with idiopathic pulmonary fibrosis (IPF). This study may help physicians and researchers better understand how best to treat patients with IPF in the future.

Multinational Study of Efficacy and Safety of Inhaled Treprostinil in Subjects With Idiopathic Pulmonary Fibrosis
Study RIN-PF-303 is a multinational study designed to evaluate the superiority of inhaled treprostinil against placebo for the change in absolute forced vital capacity (FVC) from baseline to Week 52.

Nintedanib for the Treatment of SARS-Cov-2 Induced Pulmonary Fibrosis
Currently, there is no approved treatment for COVID-19 in France, either for the acute phase, nor for the late chronic phase. the investigator suggest that nintedanib has the potential to block the development of lung fibrosis when initiated early enough to inhibit the activation of mesenchymal cells and the progression of virus-induced pulmonary fibrosis. Computerized Tomography (CT) manifestations of fibrosis or fibrous stripes are described in COVID-19 (Ye, Eur Radiol 2020). Pan et al observed fibrous stripes in 17% patients in the early phase of the disease (Pan, Eur Radiol 2020). Ye et al observed bronchiectasis in 2 patients (15.4%) ...

Optimising Screening for Early Disease Detection in Familial Pulmonary Fibrosis
In this study the prognostic value of the current screening parameters for familial pulmonary fibrosis (FPF) will be investigated by looking at the screenings of 200 first-degree relatives of patients with FPF. Also insight in the natural history of early FPF, and the necessary interval between screenings visits will be investigated.
