Fidgety Movements in Cystic Fibrosis
Cystic FibrosisVery low birth weight infants who are at risk for chronic lung diseases may also be at risk for brain anomalies such as increased echogenicity, leukomalacia and intracranial hemorrhage. Infants with bronchopulmonary dysplasia have been reported to have worse neurodevelopmental outcomes than healthy infants. It has also been pointed out that babies with prolonged and recurrent apneas during sleep may have weak General Movements (GMs) repertoire. It has been mentioned that motor development retardation may also occur in neurodevelopmental diseases, genetic diseases and chronic lung diseases, as well as in cystic fibrosis. In infants with cystic fibrosis, motor development may be affected by increased incidence of hospitalization, previous infections, malnutrition, respiratory and digestive system disorders. There is no research done with GMs assessment to determine motor dysfunction in infants with cystic fibrosis and this topic is open to research. Having more information about the motor development of babies by determining the motor characteristics and motor performance of infants with cystic fibrosis, it may be possible to start the disease-specific physiotherapy and rehabilitation programs as early as possible. For this reasons, in the study the investigators aimed to investigate the characteristics of GMs in the "Fidgety" period of 3-5 month term infants diagnosed with cystic fibrosis, to determine the motor performances and to investigate the relation between the GMs characteristics and the features of the disease. The hypotheses the investigators have set for this study are listed below; Ho: Spontaneous movements of the "Fidgety" period of infants diagnosed with 3-5 months of cystic fibrosis are not different from normal infants. H1: Spontaneous movements of "Fidgety" period of infants diagnosed with cystic fibrosis between 3-5 months are different from normal infants.
Upper and Lower Airway Colonization in Cystic Fibrosis Patients After Lung Transplantation
Cystic FibrosisLungtransplantation1 moreA hot topic in lung transplantation is the treatment of persisting sinus disease/colonization in CF patients to prevent descending graft colonization and chronic allograft dysfunction. From 2012, the Hannover transplantation group has been using a conservative approach with topical nasal inhalation. It is now necessary to analyse the impact of the new approach on graft colonization, incidence of BOS, symptoms, QoL etc in comparison to a historical cohort. It is also important to establish which is the best among the different inhaled antibiotic regimens currently available.
Interactive Video Game Responses in Cystic Fibrosis
Cystic FibrosisCystic fibrosis (CF) is a disease that affects multiple systems, however, the accumulation of secretion in the airways contributes to the fact that pulmonary complications are the main responsible for the high rates of morbidity and mortality. Physical exercise can be an important component in the treatment of these patients, and modalities such as Nintendo Wii and Xbox One stand out as feasible and innovative methods that can contribute to increase adherence to rehabilitation. Thus, the objective of this study is to compare the cardiorespiratory responses during a maximal exercise test with the use of Nintendo Wii and Xbox One in patients with CF and healthy individuals. Patients with a clinical diagnosis of CF, aged from 6 to 30 years old and in stable clinical conditions will be included. For healthy individuals, those who are considered healthy from the application of a health questionnaire and also aged from 6 to 30 years old will be included. Patients in both groups with cardiopathies, musculoskeletal diseases, neurological diseases or signs of pulmonary exacerbation will be excluded. Participants will complete a questionnaire to assess their level of physical activity. Afterwards, cardiopulmonary exercise test (CPET) will be performed (visit 1), followed by the use of video games (visit 2). The video game will be practiced using a Nintendo Wii and a Xbox One (10 minutes each). A rest of 10 minutes will be provided between the use of each video game. During the interactive games, patients will use an accelerometer to assess the level of physical activity. In parallel to this, healthy subjects will be invited to perform the same tests in two visits. To evaluate the perception of fatigue, the OMNI scale will be used. In addition, individuals will be asked to evaluate their level of satisfaction after each game.
Impact of Respiratory Viral Infections in Infants With Cystic Fibrosis.
Cystic FibrosisRespiratory Viral InfectionRespiratory Viral Infections (RVI) are particularly frequent in young children. Old data mention the deleterious role of some viruses such as the Respiratory Syncytial Virus in young children with cystic fibrosis (CF). However, recent epidemiological data on RVI in CF children are rare and the impact of most frequent viruses such as human rhinoviruses is usually not correctly evaluated. The aim of this study is to assess the frequency of lower and upper RVI during a 1 year follow-up in CF infants and to evaluate the impact of RVI at a clinical, microbiological and therapeutic level. Our hypothesis is that frequent and/or clinically severe RVIs have the worst impact in the short term and without any particular link with a specific virus as previously described.
Real-life Follow-up of Cystic Fibrosis Patients Treated With Ivacaftor+Lumacaftor (Orkambi*)
Cystic FibrosisThe purpose of the study is to examine the real-life safety and effectiveness of the novel combination ivacaftor+lumacaftor in eligible patients with cystic fibrosis (CF). All patients with CF were eligible if they were 12 years and older, started ivacaftor+lumacaftor outside of a clinical trial between December 15th 2017 and December 15th 2018 in an accredited CF center in France. Patient followed-up is based on standardized recommendation of the French Cystic Fibrosis Society. Each patient is followed 1 year.
Kinetics of YKL-40 Protein in Serum of Cystic Fibrosis Patients
Cystic FibrosisYKL-40 is proposed as a biomarker of various inflammatory disease diabetes and lung disease including cystic fibrosis. In those cross-sectional studies, a unique value of YKL-40 is used to correlate with clinical, physiological, or biological determinants of disease severity (like FEV1 for example in lung disease). There is only one longitudinal study that showed a correlation between circulating levels of YKL-40 and the decline of lung function in smokers sampled from the general population. In order to better understand the potential role of YKL-40 in CF pathophysiology, and to determine its potential role as a biomarker of disease evolution, it is essential to proceed with further clinical evaluation. The investigators propose to perform an observational prospective cohort study to determine if variation of YKL-40 concentration over 24 months correlates with the clinical evolution of the patients.
Social Determinants in Chronic Disease in British Columbia
Cystic FibrosisDiabetes Mellitus Type I1 moreAnyone who practices clinical medicine will understand that socially disadvantaged children will have worse health outcomes, no matter what the underlying condition might be. There is limited prospective data on the effects of social deprivation on children in BC and there is none concerning the effects of social deprivation on children with chronic diseases. In order to generate relevant data for those who manage children with chronic diseases in BC, the investigators wish to perform an observational study of the relationship between questionnaire-derived social variables and measured outcomes in children with cystic fibrosis, type 1 diabetes, and chronic kidney disease. Our working hypothesis is that there is an association between social determinants of health (income, education, race) and health outcomes in children with cystic fibrosis, type 1 diabetes and chronic renal failure, that is independent of access to health care (assessed by distance to nearest specialty clinic and number of clinic visits in the last year).
Biomarkers of Iron Homeostasis and Responses to Cystic Fibrosis Pulmonary Exacerbation (CFPE) Treatment...
Cystic FibrosisThe goal of this study is to identify chemical compounds in the blood and sputum (i.e., biomarkers) that are associated with objective measurements of health status in patients with cystic fibrosis (CF). This study builds upon observations that blood levels of hepcidin-25, a protein that regulates how the body uses and stores iron, vary during CF pulmonary exacerbation (CFPE).
Clinical Evaluation of NeoPlex4 Assay and NeoPlex System
Adrenal HyperplasiaCongenital2 moreThe purpose of this study is to assess the agreement of clinical performance between the proposed NeoPlex 4 assay and NeoPlex System and the comparator devices in clinical use in newborn screening programs for detection of T4, TSH, 17-OHP and IRT.
Clinical Course and Changes in the Respiratory Microbiota Based on Antibiotic Treatment in Patients...
Bronchopulmonary InfectionBronchopulmonary infection is the most common and serious complication in the evolutionary course of cystic fibrosis (CF). Administration of antibiotics adapted to infecting pathogens is one of the key issues for its management. However, more than half of patients with CF have chronic respiratory infections for which infectious agent remains unknown leading to empirical antibiotic therapies that are not adapted to the causative agents. Recently, new technologies have been applied for the description and characterization of microbial agents in CF patients including molecular biology techniques that allowed us to detect and to identify new and/or emerging pathogens. Moreover, more sophisticated molecular techniques such as pyrosequencing and PCR amplification and cloning lead us to demonstrate the huge microbial diversity associated with chronic bronchopulmonary infections in this population. Otherwise, a metagenomic approach revealed the extraordinary complexity of the respiratory flora in these patients and, somewhat unexpected, abundance of anaerobes, viruses, and bacteriophages. In addition, it has been shown that some antibiotics commonly used in clinical practice for the treatment of respiratory infections were able to induce these bacteriophages, suggesting the existence of lateral gene transfer by transduction. The human microbiome is the set of microbial communities associated with the human body and represents all living microorganisms in the body. Its role in the immunity development has recently been demonstrated suggesting that changes in this ecosystem play a critical role in evolution of several human diseases. For example, in obesity it has been shown that there is a relationship between the intestinal human microbiota and nutritional and metabolic status of the hosts and specific alterations of these intestinal microbiota may represent a metagenomic signature of this disease. Evolution of the respiratory microbiota in patients with cystic fibrosis, whose nutritional status is often impaired (chronic malnutrition due to disorder of digestive absorption) and receiving regular antibiotic treatments remains unknown to date. Characterization of this ecosystem and its role is a critical step to understand the evolutionary course of the disease. The main objective of this seminal study is to describe and to characterize the respiratory microbiota from sputum samples obtained from a limited number of selected patients with CF from 5 regional care centers (CRCM) from South of France (Mucomed network) (2 patients per center : 6 adults and 4 children), with similar clinical, microbiological and functional status before and after a cure of antibiotics. Different microbiological tools will be used including axenic culture systems, co-culture on amoebae in order to to isolate and to identify the microbial communities. Identification of bacteria will be done using MALDI-TOF mass spectrometry and/or molecular techniques. Moreover, 16S rRNA PCR amplification followed by cloning and sequencing of PCR products from the same sputum sample will be carried out to identify and to compare the bacterial species identified using molecular methods. In a second step, once the respiratory microbiota was characterized, it will be interesting to develop a dedicated microarray that will allow to detect all the bacteria identified in the first stage of the project and to assess its relevance on a larger cohort of patients with CF by studying the correlation between the respiratory microbiota and clinical status of patients according to the prescribed antibiotic treatments. This study will open new clinical perspectives and will help us to determine the potential role of antibiotics on the microbiota evolution during treatment according to regional health care practices. This will contribute to better understand the role of the microbiota in the evolution of these chronic respiratory infections. It could be the first step for innovative therapeutic strategies, taking into account the balance of complex microbial flora and possibly evolving according to antibiotic therapies. It could also form part of a larger preventive strategy against transmission of specific pathogens in CF.
