The aim of the study is to identify a link between the new CFTR modulators and physical activity in cystic fibrosis patients. The triple combination of CFTR modulators (ELEXACAFTOR / TEZACAFTOR/ IVACAFTOR) has recently changed the management of cystic fibrosis. This treatment has been shown to rapidly improve patients' respiratory function, with a gain in FEV1 at 1 month ranging from 10.4% to 13.6%. It also reduces the number of respiratory exacerbations and improves the nutritional status and quality of life of treated patients. To date, there is limited data on the impact of these new therapies on physical activity. Few studies have investigated changes in exercise or physical activity parameters under ELEXACAFTOR / TEZACAFTOR/ IVACAFTOR. The 6-minute walk test is a validated field test used routinely to assess the exercise capacity of patients with chronic respiratory diseases, including cystic fibrosis.
This project will use literature analysis, expert research, real-world data mining and other methods to investigate the current status of the application of antimicrobial aerosolized inhalation in healthcare institutions, combine expert recommendations and real-world data analysis results to explore potential risk points in the process of antimicrobial aerosolized drug delivery, and sort out the key points of drug use management in healthcare institutions and the key points of regulatory recommendations for healthcare institutions.
In a prospective observational cohort study (n = 100), the investigators aim to assess the correlation between cardiac biomarkers, advanced echocardiography and cystic fibrosis genotype and severity and determine whether these are prognostic markers of heart disease in patients suffering from cystic fibrosis (CF).
With this study, the investigators first want to investigate the respiratory tract microbiome of cystic fibrosis patients. To achieve this, the investigators will collect longitudinal samples of saliva, throat and sputum and process these to determine the microbial composition and compare them over a timecourse of a year. Secondly, the investigators aim to study the influence of a topical microbiome therapy (throat spray) on the microbiome of the upper and lower respiratory tract in cystic fibrosis patients after administration for 6 weeks. Bacterial and cytokine profiles of salivary, throat and sputum samples will be monitored before, during and after intervention.
Progressive destruction of the lungs is the main cause of shortened life expectancy in people with cystic fibrosis (pwCF). Inflammation and respiratory infections play a key role in CF lung disease. Previous studies have shown that an increase in inflammatory markers predicts structural lung damage. Close monitoring of pwCF is crucial to adequately provide optimal care. Pulmonary management for pwCF involves treating infections and exacerbations and promoting exercise and mucociliary clearance to slow or prevent structural lung damage. To evaluate the treatment and incite timely interventions it is important for the pulmonary physician to be well-informed about the condition of the lungs. The main monitoring tools in regular CF care are lung function, sputum cultures, symptom reporting and more recently imaging by chest computed tomography (CT-scan) or magnetic resonance imaging (MRI). Strangely enough, there are currently no monitoring tools used in clinics to measure inflammation in the lung, although this is a main factor for progressive lung disease. New highly effective modulator therapy (HEMT) such as elexacaftor/tezacaftor/ivacaftor [ETI, Kaftrio®] is transforming CF treatment, vastly improving lung function and reducing exacerbations. Initial CFTR modulators like ivacaftor and lumacaftor/ivacaftor also improved lung function and reduced exacerbations, but studies showed that lung inflammation was still present. The long-term impact of ETI and its effect on inflammation is not yet known. Thus, monitoring pwCF on HEMT may be different from before, as lung damage seen on chest CT will be less apparent and lung function will improve considerably, therefore not being adequate markers for subtle changes in the lungs. Thus, the focus of monitoring in the era of highly effective CFTR modulators needs to change preferably focusing on measuring lung inflammation. An ideal monitoring tool for lung inflammation in pwCF should be non-invasive, efficient, and provide accurate and sensitive results. Currently, sputum and BAL are the most common methods for assessing inflammation, but BAL is invasive and sputum may not always be available. Exhaled breath analysis by the electronic nose (eNose) or gas chromatography-mass spectrometry (GC-MS) of volatile organic compounds (VOCs) shows promise as a non-invasive monitoring tool. Other promising markers and techniques are inflammatory markers in the blood (cytokines and micro-RNA (miRNA)) and urine. Thus, the objective of this project is to design novel, minimally invasive monitoring techniques capable of identifying lung inflammation in pwCF undergoing highly effective CFTR modulator therapy (ETI) compared to those not using CFTR modulators. The efficacy of these innovative techniques will be evaluated and verified against inflammatory markers in sputum, spirometry, and validated symptom and quality of life scores.
Recently trial data has shown that the medicine KaftrioTM (Elexacaftor/ Tezacaftor/ Ivacaftor) improves lung function in children aged 6 to 11 years who have cystic fibrosis (CF). This has led to it being licensed for use in the UK in 2022 and is now being prescribed in this age group. There is little information in trials however that shows the effect KaftrioTM (ETI) has on the gut or liver in this age group. Previous studies in the GIFT-CF series (NCT 03566550, NCT04006873 and NCT04618185) has found differences in the functioning of the gut between adults with CF and healthy controls but it is not known whether these differences are present in those aged 6 to 11 years. This study is a significant amendment of the GIFT-CF3 protocol (NCT04618185) that aims to measure gut function using magnetic resonance imaging (MRI) in children with CF before and after starting ETI. This study also aims to opportunistically measure lung function and structure using MRI and explore how the liver can be measured using MRI in this age group. The study is split into 2 stages. The first is a pilot stage using the modified GIFT-CF protocol recruiting 3 children with CF before starting ETI and 3 healthy volunteers. This is to determine we are able to successfully perform these scans in these age groups. If successful, the second stage will recruit a further 12 children with CF before they start ETI. This will take our cohort up to 15 children with CF. This cohort will then be rescanned 6 months after starting ETI using the same scan protocol.
The goal of this observational study is to provide optimal monitoring and support when initiating ETI treatment in eligible persons with cystic fibrosis (aged 12 y +) and to document on a daily basis, from 72 hours before the start of treatment and then for 14 days i) i) FEV1 changes (home spirometry), ii) ii) respiratory symptoms changes, iii) any possible side effects. Through a dedicated electronic platform, these data will be monitored every day by the medical team, which will be fully available for any questions or concerns patients may have.
Cystic fibrosis is a multi-organ disease. It most often results from a genetic mutation, the delta F508 mutation, which prevents the expression of the CFTR 'régulateur de conductance transmembranaire de la fibrose kystique) protein. If the poor prognosis of the disease is correlated to the pulmonary damage, we observe, at the naso-sinus level, a significant functional impact, with chronic rhino-sinusal damage that can alter the quality of life of patients. In addition to this functional impact, some studies suggest that these chronic naso-sinus attacks are involved in the creation of a bacterial reservoir that is secondarily responsible for pulmonary colonization and therefore partly responsible for the poor prognosis of the disease. The clinical and paraclinical examinations can be used to determine the extent of these disorders. Their functional impact can be assessed using quality of life questionnaires such as the SN-5 scale. Treatment with CFTR modulators in patients with mutations compatible with the treatment seems to transform their vital prognosis. The scientific rationale of this treatment consists in restoring the activity of the CFTR protein, allowing the recovery of the hydro-electrolytic balance of the mucous secretions, and thus reducing the viscosity of the biological fluids. The various studies carried out all prove a dramatic improvement in pulmonary parameters under treatment, with very limited toxicity. A marketing authorization for this treatment has been issued on the European market for patients over 18 years of age in 2020, for children over 12 years of age in 2021, and will soon be issued for children aged between 6 and 11 years. Since the pathophysiology of pulmonary and nasosinus involvement are similar, and since this treatment will be marketed for children between 6 and 11 years of age, we expect an improvement in rhino-sinus symptomatology. To date, clinical studies have focused primarily on pulmonary outcomes. There are only few publications dealing with the evolution of nasosinus symptomatology under treatment, and none concerning the pediatric population. The aim of our study is to evaluate the evolution of naso-sinusal symptomatology under treatment with CFTR modulators in children aged 6 to 11 years. This will allow us to confirm or deny the interest of these treatments in the extra-pulmonary manifestations of the disease.
Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.
