Low-field Magnetic Resonance Imaging of Pediatric COVID-19
Sars-CoV-2 InfectionLung Fibrosis1 moreSARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) is a new coronavirus and identified causative agent of COVID-19 disease. They predominantly cause mild colds but can sometimes cause severe pneumonia. The long-term consequences are still largely unexplained and misunderstood, especially in children and adolescents. The aim of this study is to assess the frequency of pulmonary skeletal changes in pediatric and adolescent patients using low-field magnetic resonance imaging (LF-MRI) in the setting of proven past SARS-CoV-2 infection.

Microaspiration in Pulmonary Fibrosis
Idiopathic Pulmonary FibrosisHypothesis 1: Microaspiration, as diagnosed by bronchoalveolar lavage (BAL) pepsin, is common in patients with IPF. Hypothesis 2a: Baseline clinical variables and co-morbid conditions are risk factors for microaspiration in patients with IPF. Hypothesis 2b: Baseline biological variables reflecting alveolar epithelial injury and inflammation are markers of microaspiration in IPF. Hypothesis 3a: Microaspiration will lead to a more rapid rate of decline in pulmonary function. Hypothesis 3b: Microaspiration will lead to higher rates of urgent medical care use (i.e. unscheduled clinic visit, emergency room visit, or hospitalization).

Herpesvirus in Idiopathic Pulmonary Fibrosis
Lung DiseasesHerpesvirus InfectionsThe purpose of this study is to: 1) to develop a method to quantify Epstein Barr Virus (EBV) load in lung tissue of humans and to determine whether EBV viral load is significantly higher in lung tissue from patients with idiopathic pulmonary fibrosis (IPF) than in control lung tissue; 2) to determine whether EBV localized to epithelial cells in IPF lungs and to relate epithelial positivity to tissue viral load; 3) to measure viral load in induced sputum from IPF subjects over time in order to determine whether periodic active herpes virus replication occurred in the respiratory tract; and 4) to compare longitudinal measures of viral load in induced sputum with simultaneously collected saliva in order to assess the clinical utility of the two approaches.

Lung Disease Associated With Rheumatoid Arthritis
Pulmonary FibrosisPulmonary fibrosis (PF) is a condition in which the lungs of a patient become scarred and fibrous. It has been known to occur in as many as 40% of patients diagnosed with rheumatoid arthritis (RA). The cause of the pulmonary fibrosis in patients with RA is unknown. Patients participating in this study will undergo a series of tests and examinations before and throughout the study. The tests include blood and urine tests, electrical measures of heart function (ECG), chest x-rays, CAT scans, nuclear medicine scans, breathing tests, exercise tests, and fiberoptic bronchoscopy. The goals of this study are to: Estimate how common pulmonary fibrosis is in patients with rheumatoid arthritis, Describe the natural course of pulmonary fibrosis in patients with rheumatoid arthritis, Estimate the survival rate of patients with pulmonary fibrosis and rheumatoid arthritis, and Learn more about the factors that contribute to the development or progression fibrotic lung disease....

Segmental Bronchoalveolar Lavage
AsthmaPulmonary FibrosisBronchoalveolar lavage (BAL) is a diagnostic and therapeutic procedure conducted by placing a small fiberoptic scope into the lung of a patient, and injecting sterile water (saline) into the lung and removing the fluid. The sterile solution removed contains secretions, cells, and protein from the lower respiratory tract. This sample can be analyzed to provide more information about possible disease processes going on in the lungs. This protocol will be used to perform BAL, bronchial brushing, and bronchial wall biopsy in normal volunteers and patients with pulmonary disease. The samples collected during the study will be used to examine biochemical processes in the lung that may contribute to lung disease

Estimated Impact of Fungal Colonization in Cystic Fibrosis From Secondary Exploitation of MucoFong...
Cystic Fibrosis LungThe main objective of the project "MucoFong" (19021906 national french program n which Vaincre La Mucoviscidose participated: N82006/ 351) was to determine the fungi present the respiratory tract of CF patients responsible for either colonization or authentic infectious diseases. The Mucofong data allowed the team to provide for the 1st time national French guidelines for the management of CF sputum mycological analysis (MucoMicrobes work group coordinated by Prof. Plésiat published in 2015 in the REMIC book). Nevertheless, the team has a comprehensive database that it still has to analyze beyond these initial results. The main goal today is to clarify the role of fungi in the lung function degradation of these patients by studying the overall risk and estimated impact of fungal colonization in our cohort.

Determinants of Early Cystic Fibrosis Lung Disease
Cystic Fibrosis in ChildrenThe overall objective of this study is to determine the impact early nutritional and respiratory indices have on early CF lung disease. This knowledge will guide clinical management of infants with CF, who are now primarily diagnosed through newborn screening.

Prospective Evaluation of Biomarker Profiles in Idiopathic Pulmonary Fibrosis
IPFIdiopathic pulmonary fibrosis (IPF) is a progressive, fatal, fibrotic disorder of the lung. The estimated prevalence is 30-80/100,000 in the United States with incidence estimates clearly rising. A major challenge in the care of patients with IPF is determining prognosis. The natural history of IPF is usually one of inexorable decline in lung function, ultimately resulting in death from respiratory failure. However, longitudinal physiologic decline in IPF is heterogeneous and difficult to predict in individual patients. While some patients with IPF may remain stable for years, in others the disease may progress rapidly over a relatively short time. We hypothesize that peripheral blood biomarkers based on extracellular matrix and matrix-modifying molecules will improve prognostication in patients with IPF.

A Longitudinal Study of Hermansky-Pudlak Syndrome Pulmonary Fibrosis
Hermansky Pudlak SyndromeHermansky-Pudlak Syndrome (HPS) is a rare genetic disease that is associated with oculocutaneous albinism, bleeding, granulomatous colitis, and pulmonary fibrosis in some subtypes, including HPS-1, HPS-2, and HPS-4. Pulmonary fibrosis causes shortness of breath and progressive decline in lung function. In HPS patients with at-risk subtypes, almost all adults eventually develop fatal pulmonary fibrosis unless they undergo lung transplantation. The purpose of this study is to identify the earliest measurable pulmonary disease activity in individuals at-risk for HPS pulmonary fibrosis. The study also aims to develop biomarkers that will aid in understanding of the causes of HPS pulmonary fibrosis and facilitate more rapid conduct of therapeutic trials in HPS patients with mild pulmonary disease in the future.
