Comparing Chest Images From MRI to CT in Patients With Cystic Fibrosis (CF)
Cystic FibrosisThe purpose of this research is to learn more about the heart and blood vessels in the lungs of people with cystic fibrosis (CF). This study will include approximately 36 children and adults with CF and 12 children and adults without CF. The study will involve one magnetic resonance imaging (MRI) . The research also includes blood samples to look at inflammation and lung tests called spirometry and Lung Clearance Index (LCI) determined by Multiple Breath Washout test. For the CF subjects, enrollment will be timed to coincide with routine scheduled computerized tomography (CT) or the CF subject may choose to have a CT for research purposes. The MRI will be compared to CT images of the lungs. The goal is to develop better imaging that does not use radiation.
An Ocular Safety Study of Ivacaftor-Treated Pediatric Patients 11 Years of Age or Younger With Cystic...
Cystic FibrosisThis study is designed to evaluate the risk of cataracts (lens opacities) and describe the best corrected distance vision (with glasses/contacts for those who wear them) of pediatric patients with Cystic Fibrosis who are 11 years of age or younger at the time of ivacaftor treatment initiation and are receiving or planning to receive commercially-available ivacaftor in the US.
Representations of Transplantation in Patients and in Health Care Professionals
Cystic FibrosisMain objective : This project aims to have a better understanding of the influence of representations of patients with mucoviscidosis, their assistants and their medical persons in the choice of patients to accept or not lung transplantation. Specific objectives : Identify the knowledge, representations, or feelings of patients which could constitute bridles or factors of motivation to use for transplantation. Identify the knowledge, representations, or feelings of medical persons which could constitute bridles or factors of motivation to the "encouraging" proposal to patients of lung transplant. Identify the knowledge, representations, or feelings of assistants which could constitute bridles or factors of motivation to the "encouragement" of lung transplantation at its close. Identify the needs of patients, assistants and medical persons to successfully reduce these bridles to transplantation and increase the factors of motivation. Compare the representations of patients, assistants and medical persons Search representations associated with patients who refuse the transplantation and those who accept the transplantation
Multiple Breath Nitrogen Washout in Healthy and Cystic Fibrosis Adults
Cystic FibrosisHealthyThis study compares the lung clearance index (LCI) in cystic fibrosis and healthy adults obtained with two different multiple breath nitrogen washout (MBWN2) devices. Each participants will perform the test (LCI) in duplicate on each device.
Development of a New Tool for Dyspnea Measurement in Chronic Respiratory Diseases
COPD (With - Without Rehabilitation)Diffuse Interstitial Lung Diseases2 moreThe purpose of this study is the psychometric validation of a self-administered dyspnea questionnaire, usable in clinical practice in order to assess dyspnea and its impact on patients with chronic respiratory diseases.
The Carrier Rates of Pseudomonas Aeruginosa in Family Members of Children With Cystic Fibrosis
Pseudomonas AeruginosaCystic FibrosisPseudomonas aeruginosa (Pa) is the bacterium that causes one of the most consequential lung infections in people with CF. Many young children do not have Pa in their lungs but will become infected as they get older. The investigators want to learn more about how Pa is passed from person to person, especially to someone with Cystic Fibrosis (CF).
Cystic Fibrosis Related Bone Disease: the Role of CFTR
Cystic Fibrosis Related Bone DiseaseThe purpose of this study is to determine whether ivacaftor, a recently FDA-approved CFTR potentiator, improves bone micro-architecture and strength in patients with cystic fibrosis with at least one G551D CFTR mutation.
Prevention of CF Exacerbation in Childhood: PREVEC Study
Cystic FibrosisChildren5 morePulmonary exacerbations of CF are an important cause for the experienced disability of patients, respiratory symptoms, and decreases in lungfunction, which require antibiotic therapy at home or in the hospital. Therefore, prevention of exacerbations in CF is important. The aim of this study was to assess the predictive properties of inflammatory markers in exhaled breath for pulmonary exacerbations in children with CF. In addition the reliability of home monitor assessments of symptoms and lungfunction was investigated.
Using MRI to Observe Lung Changes in Infants With CF Compared to Infants Without CF
Cystic FibrosisOur research is comparing the lungs of babies and young children with CF (cystic fibrosis) to those without CF. We are looking at the blood flow in the lungs to help doctors better understand how CF damages lungs and how to prevent this damage in the future. We will use MRI (Magnetic Resonance Imaging) and special blood tests as ways to understand early changes in the lungs of babies and young children with CF. We will look at the special blood tests to see if they can work as signals for the doctors to better understand when changes are happening in the lungs. For the babies with CF, we will compare MRI images of the lungs to their CT images (also sometimes called CAT scans or Computerized Tomography). We hope that this study will help us reduce the number of X-rays and CT scans children with CF might get in the future. Because MRI's do not use radiation, this could reduce the amount of radiation exposure that children with CF would get over their lifetime.
Cough-Generated Aerosols of NTM in Cystic Fibrosis
Cystic FibrosisNon-tuberculous mycobacteria (NTM) are opportunistic pathogens normally found in soil and water that are being cultured from Cystic Fibrosis (CF) airways at an increasing frequency. They have been demonstrated to cause clinically significant lung disease in some cases and the transmission of NTM, from person to person has been proposed. There are currently no standardized guidelines for isolation of those colonized or infected with NTM. The investigators will measure particle droplet size from patients with CF who have positive sputum cultures for NTM with the hypothesis that they will be in a range that can spread infection.
