Filter by:Cystic fibrosis (CF) is a rare disease affecting one out of 4,500 newborns in France (INSERM 2021). Despite major advances in patient care over the past two decades, with significant improvements in life expectancy, cystic fibrosis remains a pathology that considerably impairs quality of life. Several studies have reported the possibility of respiratory and non-respiratory sleep disorders (SD) in patients with CF. Respiratory disorders are reported to affect 30% of children with CF (Barbosa 2020). Among non-respiratory SD, sleep onset and maintenance insomnia are well known in these patients, while chronotype abnormalities (circadian rhythm disorders) are understudied. Chronotype refers to a person's tendency to be more efficient in the morning or evening. The existence of chronotype abnormalities has been suggested in CF patients, but no precise data are available (Louis 2022). The involvement of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) protein dysfunction in the central nervous system (CNS) has been hypothesized as a contributory factor. In vivo, in a mouse model of CF, dysregulation of clock genes such as Clock, Cry2 and Per2 was found in the CNS (Barbato 2019). Among them, certain genes such as Rev-erbα could regulate endobronchial inflammation and contribute to the severity of respiratory pathology. All in all, chronotype abnormalities could be at the origin of sleep debt, impaired cognitive functions or metabolic disturbances. In the era of highly effective modulator therapy (HEMT) for the treatment of CF, the impact of these new therapies on chronotype has been understudied. Assuming that chronotype abnormalities are a direct consequence of CFTR protein dysfunction in the retina and anterior hypothalamus, HEMT should improve sleep quality. However, between 20% and 30% of adult and pediatric patients express an increase in chronotype abnormalities following initiation of treatment. Paradoxically, the perceived gain in respiratory quality of life is counterbalanced by the occurrence of these disorders. Some patients would effectively reverse their treatment in order to limit the phenomenon. A single polysomnographic study evaluated the effect of HEMT Kaftrio-Kalydeco on sleep in adults with CF (Welsner 2022). After 3 months of treatment, patients had a significant reduction in respiratory events, with no change in total sleep time, sleep efficiency or sleep architecture. Chronotype was not mentioned. Currently, no studies on chronotype in children or adults with CF have been carried out. Our hypothesis is that CF patients treated with HEMT would develop an abnormal chronotype of late sleep onset. The aim of this study is to evaluate the chronotype of children with CF treated with HEMT. Chronotype abnormalities could have major consequences for quality of life, the immune system, cognitive functions and metabolism. Systematic detection of these disorders via anamnesis, followed by diagnosis by questionnaire, actimetrics and/or urinary melatonin dosage, would enable their early management, starting with the reversal of Kaftrio-Kalydeco intake between morning and evening.
The goal of this clinical trial is to test use of losartan in those with cystic fibrosis (CF) on modulator therapy. The main question it aims to answer is if treatment with losartan improves response of the CF transmembrane conductance regulator (CFTR) channel to modulator therapy. Participants will be asked take losartan or placebo for twelve weeks and will have changes in sweat chloride levels measured as a marker of CFTR function.
Cystic Fibrosis (CF) is a rare hereditary disease with autosomal recessive transmission, affecting 1 in 4700 births in France. Numerous studies have explored the links between oral health and CF, predominantly focusing on a children population. These studies reveal hyposalivation, a risk of dental erosion, an increased prevalence of enamel structural defects, but a reduced prevalence of dental caries in CF children, potentially explained by better oral hygiene. Periodontal disease does not appear to be increased in this population, while the oral quality of life of CF patients has been insufficiently studied. Today, emerging challenges arise due to the increased life expectancy of CF patients, attributed to the rise of modulators such as Kaftrio®, resulting in an adult-majority population in France. The study of periodontal diseases, associated with oral dysbiosis, becomes relevant as they represent bacterial reservoirs that could impact respiratory complications in CF patients. To deepen understanding of the links between oral health and CF, as well as to improve oral health of these patients, it is crucial to update the specific oral profile of this population. A cross-sectional survey using a questionnaire is proposed to include a large number of CF patients in France, aiming for real-life data. This questionnaire is constructed around internationally recognized tools for comparative analysis with normative data. Collaboration with the Patients Association "Vaincre la Mucoviscidose" (VLM) facilitates questionnaire creation, dissemination, and interpretation of results.
Cystic fibrosis (CF) is the most common autosomal recessive disease that leads to early mortality in Caucasians and affects around 7500 patients in France. Progression of the disease depends on pulmonary exacerbations defined as acute deterioration of respiratory symptoms which ultimately impair lung function and quality of life. Most frequently caused by lung bacterial infections, exacerbations' effects include increased cough, increased sputum production, increased use of antibiotics, dyspnea and decreased lung function. The phenotypic variability of CF suggests the implication of other contributors especially to the CF airway disease. Beside genetic and epigenetic alterations, environmental factors - e.g tobacco smoke, air pollution, temperature changes, food intake - appear as relevant candidates. A previous review has discussed current knowledge on the effects of air pollution on the course of CF disease. Although scarce, the existing epidemiological andexperimental literature suggests a link between exposure to air pollutants and adverse health effects.Although scarce, the existing epidemiological and experimental literature suggests a link between exposure to air pollutants and adverse health effects. The EU sponsored REMEDIA project (Impact of exposome on the course of lung diseases, Grant agreement ID 874753) contributes to the understanding of the influence of the exposome on chronic obstructive pulmonary disease (COPD) and CF. Objective of work package 3 within the REMEDIA project is the development of a mobile environmental sensor toolbox that is capable to assess the external exposome. The biomarkertoolbox was developed and tested in a proof-of-concept study carried out in healthy volunteers. The next step is to validate the collectionof exhaled breath condensate (EBC) in a real-life study. In this aim, the objective of the present study will be to assess the feasibility of EBC collection in CF patients and healthy individuals
The development of CFTR (cystic fibrosis conductance transmembrane regulator) modulators for people with cystic fibrosis (pwCF) and eligible for these treatments is a true therapeutic revolution. The major beneficial effect of CFTR modulators (CFTRm) on pulmonary function and the reduction of pulmonary exacerbations should have a considerable impact on the quality of life and patient's life expectancy. Data on the impact of CFTRm on glucose tolerance abnormalities are still very fragmentary. The investigators can think that their use, earlier and earlier in the history of the disease, will transform the evolutionary trajectories of patients on the respiratory, nutritional and metabolic levels. Diabetes represents a major challenge in the management of pwCF because it is a factor in morbidity and mortality at all stages of the disease, from children to patients with terminal respiratory failure requiring lung transplantation. Early abnormalities in glucose tolerance observed in childhood, before the stage of diabetes, are also associated with poor pulmonary and nutritional outcomes. Experimental data suggest a positive effect of CFTRm on insulin secretion. However, investigators do not currently know the impact of CFTRm in patients with very early glucose disorders or at the stage of diabetes treated with insulin. Recently continuous glucose measurement (CGM) devices represent very effective tools for assessing abnormalities in glucose tolerance before the stage of diabetes and for monitoring patients treated with insulin.
The main objective of the study is to determine the impact of cystic fibrosis affecting a child on the parents' quality of life, their possible anxiety and depressive symptoms, their general fatigue and the feeling of burden in these caregivers.
The goal of this clinical trial is to analyse the impact of a telematic assessment and monitoring protocol in people with cystic fibrosis, in order to identify exacerbations early, thus preventing loss of lung function and maintaining quality of life. Participants will be assigned to one of 3 study groups: Control group (CG-1): will receive their usual physiotherapy treatment; Treatment group (TG-2): will receive their usual physiotherapy treatment, plus explanation of the use of the monitoring equipment; Treatment and follow-up group (TGF-3): will receive their usual physiotherapy treatment, plus explanation of the use of the monitoring equipment, plus telematic control of exacerbations with feedback from the physiotherapist.
Assessment of the outcome of patients not concluded fir cystic fibrosis, either symptomatic patients or asymptomatic children detected by newborn screening for cystic fibrosis. The aim is to identify patients potentially at risk of progressing to the clinical spectrum of cystic fibrosis
The goal of this observational prospective study is to determine the health impact of parenthood on United States (US) people with CF in the era of CF transmembrane regulator protein (CFTR) modulators. The investigators will collect physical and mental health data to comprehensively evaluate the impact of parenthood in CF with widespread highly effective CFTR modulator use. The main hypotheses this study aims to examine are: H1: Parents with CF and moderate-to-severe depression have more rapid change in ppFEV1 (percent predicted forced expiratory volume in one second) versus those with mild or no depression. H2: Parents with CF who have more parental responsibility and/or stress have more rapid ppFEV1 (percent predicted forced expiratory volume in one second) change than those with less responsibility/stress H3: Parents using CFTR modulators have decreased ppFEV1 (percent predicted forced expiratory volume in one second) change versus those not using CFTR modulators Participants will complete quarterly surveys during the first year of parenthood and biannual surveys, thereafter, using the computer-based survey system on an iPad protected for infection control or via personal device or computer via emailed survey link.
Cystic fibrosis (CF) is a life-threatening exocrine gland disease that is often diagnosed in childhood, and its incidence tends to increase and affect physical and mental health.The purpose of this study is to evaluate the effectiveness of the Intervention Program Based on Strengthening the Psychological Resilience of Children Diagnosed with Cystic Fibrosis and Their Mothers, prepared for children with CF (8-12 years old) and their mothers.In the first stage, the CF experiences of children with cystic fibrosis and how they perceive these experiences will be examined with visual phenomenology, and their mothers' CF experiences and perceptions will be examined with phenomenology. In this regard, 10 children will be asked to draw pictures and their pictures will be analyzed. In-depth individual interviews will be held with mothers.In the 2nd stage, the effectiveness of the Intervention Program Based on Strengthening Psychological Resilience for Children Diagnosed with Cystic Fibrosis and Their Mothers will be determined with a pre-test-post-test randomized controlled experimental design.In the literature review, Gpower analysis was performed (α: 0.05, β: 0.99, d: 1.88) based on the results of studies conducted with children diagnosed with CF and their parents, similar to this study, and 15 samples were used for each group. It is planned to recruit people. Considering the possibility of data loss in the study, it was always deemed appropriate to include 22 people for the group. It was planned to sample a total of 88 children with CF and their mothers, 44 in the intervention group and 44 in the control group. In the 3rd stage, after the experiment, the participants' experiences regarding the intervention program will be examined through interviews and qualitative research method. Thus, qualitative interviews will be conducted before and after the experiment. Data will be collected using these tools: Children; Child and Mother Descriptive Characteristics Form, Semi-Structured Interview Form,Respiratory Function Test, Reorganized Cystic Fibrosis Questionnaire, Psychological Resilience Attitude and Skills Scale and Functional Disability Inventory; Mothers; The Revised Cystic Fibrosis Questionnaire, The Depression Anxiety and Stress Scale, Post-Traumatic Growth Scale and Brief Psychological Resilience Scale. Measurements will be taken before the intervention, after the intervention, at the 1st and 3rd months.
