Active clinical trials for "Cystic Fibrosis"

This study aims to assess the role of some factors which can influence the chest physiotherapy adherence in adult with cystic fibrosis. At first, we are going to try to consider the adherence of chest physiotherapy. Then, after dividing the patients into two groups - adherent or not adherent - we will attempt to identify the factors which can influence this adherence. It consists in a short questionnaire that the patient will fill during usual visits. The hypothesis is that the following factors can play a role in adherence of chest physiotherapy: Age Age of diagnostic Sex Fev1 Number of antibiotic course Anxiety/depression Work time Socio-professional category Individual situation Physiotherapy with liberal physiotherapist and transport time Sport practice Family support Feeling of work time burden Feeling of physiotherapy efficiency Feeling of physiotherapy burden

Recent improvements in cystic fibrosis management have enabled an important subset of patients to maintain normal spirometry. Nevertheless, even in these patients with normal spirometry, chest computed tomography (CT) might identify structural lung abnormalities such as bronchiectasis, mucus plugging, bronchiolitis and air trapping. Lung clearance index (LCI) has been shown to correlate well with structural pulmonary alterations seen on CT even in CF patients with well-preserved spirometry. In cystic fibrosis, a high LCI is associated with a worse feeling of illness assessed by the Cystic Fibrosis Questionnaire-Revised (CFQ-R). School-aged CF patients with normal spirometry also have normal aerobic function as assessed by peak oxygen uptake (V̇O2) measured during symptom-limited incremental cardiopulmonary exercise test. However, the ability of LCI to predict ventilatory abnormalities appearing at exercise in CF patients has not been investigated. The investigators therefore aimed to compare physiological parameters at exercise between CF patients with elevated LCI (i.e., LCI above the upper limit of normal [ULN]) and patients with normal LCI, all with preserved spirometry.

The results of the annual check-up will be collected to evaluate the best urinary marker for fractional sodium excretion and salt status will be correlated to clinical outcome measures.

Objectif Principal - To evaluate the intensity and frequency of pain episodes in patients with cystic fibrosis followed at the cystic fibrosis center of Rouen University Hospital, Normandy, France. Objectifs secondaires To assess the relationship between pain and disease severity. To assess the relationship between pain and the age of the patient. To describe the pain locations. To describe the use of pharmacological or nonpharmacological treatment. To evaluate the procedural pain.

Adults with CF regularly receive anti-infective therapy that can result in impaired hearing. Recent studies have identified that up to 50% of adults with CF have hearing loss with resulting significant impact on quality of life. At present, however, there is no national recommendation to screen for hearing loss within adult CF. Formal hearing tests are costly, require specialist staff and equipment and require further outpatient visits resulting in significant impact on health, social and financial resource. We propose to analyse over a 12 month period at two adult cystic fibrosis centres in London whether outpatient tablet based audiometry testing and web-based hearing apps are able to accurately screen for ototoxicity in adults with CF, and whether these methods of screening are acceptable. The results of this study will aim to streamline audiometry screening to improve detection rates, reduce cost of healthcare, enable equity in service delivery, and minimize disruption to the patient's social and work-life using smart technology.

This qualitative longitudinal study is designed to elicit and thematically analyze the perspectives of SIMPLIFY subjects about treatment withdrawal research and treatment burden in the context of triple combination CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) modulator therapy (TCT). Cohorts will be determined based on sub-groups of the assigned treatment arms from the SIMPLIFY study. Participants will be asked to participate in two interviews; the first interview will be conducted at the completion of the SIMPLIFY study and the second interview will be conducted approximately 4 months after the first interview. Trained research staff will conduct the semi-structured interviews that will be audio-recorded and transcribed for thematic analysis. Each interview should last between 30-60 minutes.

The aim of the study is to describe the evolution of caloric intake in patients with cystic fibrosis with an indication to start treatment with Elexacaftor/Tezacaftor/Ivacaftor according to the Marketing Authorization, between the start of treatment and at 12 months.

Urinary intestinal fatty acid binding protein (i-FABP), a marker of intestinal mucosal cell damage, has recently been proposed as a clinically useful measure in the early detection of necrotizing enterocolitis (NEC). However, there are no data on urinary i-FABP in meconium obstruction of prematurity (MOP). This study aimed to evaluate urinary i-FABP in MOP patient as a marker for early detection.

Accurate identification of lower respiratory tract pathogens is standard of care in the management of CF patients and it is therefore recommended to perform regular bacterial cultures, at least once a year, but some even recommend monthly cultures. This can be done through different methods, of which sputum and bronchoalveolar lavage (BAL) are the gold standard. However, BAL is an invasive method, not designated to repeat monthly. Therefore, the diagnosis of lower respiratory tract infections can be challenging in the non-expectorating CF patient. Other methods, such as induced sputum (IS), cough swabs and nasal swabs, have been developed to obtain bacterial cultures in these patients. Studies have investigated the reliability of these different sampling methods, however, with controversial conclusions.
