Filter by:Cystic fibrosis (CF) is the most common inherited condition in the United Kingdom, affecting approximately 10,837 people. It is well recognised that regular exercise is clinically important for people with CF. Exercise function measured by the maximal oxygen consumption during a cardiopulmonary exercise test is often reduced in people with CF and this has been attributed to multiple factors including, altered heart and blood vessel function, muscle function, reduced physical activity levels and poorer sleep quality. New medicine (modulators) have become available for many people with CF. Modulators appear able to reduce sweat chloride concentrations, improve lung function and reduce the frequency of pulmonary exacerbations in people with CF. Little evidence exists to show how they may have changed the fitness and underlying mechanisms responsible for this in people with CF. This study aims to: 1. determine the exercise function 2. determine the blood vessel function 3. determine body composition 4. determine physical activity and sleep levels in people with CF on modulator therapy compared to a healthy controls group.
The goal of this clinical trial is to investigate the effects of a-12-week virtual reality exercise program, applied as tele-exercise, on the exercise capacity of children with cystic fibrosis, whose physical activity level is further restricted during the pandemic. The main questions it aims to answer are: Does aerobic tele-exercise increase functional capacity in cystic fibrosis patients? Will there be a difference in treatment outcomes between the virtual reality group and the online exercise group? Participants will be randomized into two groups; virtual reality group and online group. Physical activity will be provided to the virtual reality group in the form of team activities in a virtual environment, and the other group will be provided online exercises at their home. For this purpose, virtual reality headsets will be provided to patients to give the impression of a natural, immersive environment and realistic experience. Researchers will compare exercise compliance and functional capacity between the virtual reality group and the online group.
This is a double-blind, phase 2 study to evaluate safety and efficacy of rosuvastatin in comparison to placebo after 2 years in patients with compensated cirrhosis.
This project will determine the health impact of parenthood on people with cystic fibrosis (CF). The study team will use retrospective data to provide relatively immediate evidence on parenthood's effect on pulmonary health.
Crohn's disease (CD) is a chronic transmural inflammatory bowel disease. Prolonged episodes of inflammation can lead to intestinal fibrosis, leading to intestinal stenosis and obstruction. Inflammatory stenosis can be alleviated through anti-inflammatory treatment, while fibrotic stenosis requires endoscopic dilation or surgical treatment. Early detection of the presence and severity of intestinal fibrosis in CD is the key to treatment strategies. Currently, there are certain limitations in the non-invasive evaluation methods for intestinal fibrosis, and it is urgent to develop a new imaging method to achieve non-invasive diagnosis of the degree of fibrosis. Fibroblast activation protein (FAP) is a marker of intestinal fibrosis in CD. Based on the principle that fibroblast activation protein inhibitor (FAPI) can specifically bind to FAP, FAPI radioactive tracers can achieve targeted tracing and quantification of FAP in vivo. Therefore, 18F-FAPI positron emission tomography (PET) imaging technology has a good application prospect in the noninvasive diagnosis and evaluation of CD intestinal fibrosis. Based on the successful testing of 18F-FAPI PET imaging in the early stage of the project team to evaluate the nature of CD intestinal stenosis, this project intends to take patients with CD intestinal stenosis as the research object, and use postoperative histopathological analysis as a reference index to evaluate the role of 18F-FAPI combined with 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose(18F-FDG) PET imaging in the qualitative diagnosis of CD intestinal wall fibrosis, as well as the differential diagnosis ability of inflammatory and fibrous stenosis in CD patients, and establish a diagnostic model and evaluation system. Achieving a noninvasive, stable, and objective diagnosis and evaluation of the degree of intestinal fibrosis in CD patients at the molecular level will provide imaging evidence for treatment decision-making, progress, and prognosis of CD patients, and also play an important support role in the development of anti fibrosis drugs, selection of suitable patients, and efficacy evaluation.
In cystic fibrosis (CF) renal base excretion is impaired, due to mutations in the Cystic Fibrosis Transmembrane Regulator (CFTR) gene, since CFTR function is crucial in regulation of the kidney's HCO3- excretion. The investigators suggest that challenged urine HCO3- excretion is a biomarker of CFTR function, which can be used to evaluate the extent of CFTR dysfunction and the possible correcting effects of CFTR modulating therapy. This study aims to evaluate changes in challenged urine HCO3- excretion in CF patients, who are currently in treatment with the triple CFTR modulator combination therapy, Elexacaftor/tezacaftor/ivacaftor (ETI), before, during, and after a short treatment pause.
The exercise test provides prognostic information about clinical outcomes and quality of life to optimize care for cystic fibrosis patients (pwCF). The exercise test identifies the causes of exercise restriction, adverse exercise reactions, and exercise-related symptoms. The results help to determine and evaluate the impact of exercise programs at PWCF. Peak oxygen uptake (VO2peak) is a prognostic measure of maximum exercise capacity that usually worsens as CF lung disease progresses. The recommended gold standard exercise test at PWCF is a cardiopulmonary exercise test (CPET) performed on a loop ergometer to assess VO2peak and cardiopulmonary responses to exercise. the recommended incremental protocol, consisting of 1-minute phases, should reach VO2peak within 8-12 minutes. Trained operators perform cpets with complex and expensive laboratory equipment, and it is inaccessible and little used by many people internationally. Step tests are low-cost, portable, easily standardized and require minimal space to perform. The 3-Minute Step Test (3MST) is an externally paced test for the assessment of exercise tolerance set at 30 steps/minute for 3 minutes. In adults with CF, 3MST is useful for assessing oxygen desaturation and predicting future increased use of healthcare services. Limitations include the ceiling effect in less severe CF lung disease, and it is very difficult for some with more advanced lung disease. An incremental maximum A-STEP step test has been developed to assess exercise capacity in the CF lung disease December, without floor or ceiling effects, within clinical space constraints and the need for strict infection prevention. A-STEP is a new incremental maximum step test to assess exercise capacity in PWCF without floor or ceiling effects, as an alternative field test to CPET.
Hemorrhoidal disease (HD) is a common health problem, affecting up to 38,9% of adult population. HD is also a common finding in up to 36% of cirrhotic patients, as hemorrhoidal plexus is a possible site of portosystemic venous anastomosis. Cirrhotic patients represent a group often neglected in clinical trials so, little is known about the optimal treatment for HD these patients. The objective of this study is to prospectively evaluate the efficacy and safety of treatment of grade I, II and III internal HD with polidocanol foam in cirrhotic patients.
This is a 3-part, single-ascending dose Phase 1a randomized, double-blind, placebo-controlled study in healthy volunteers (Part A) and multiple-ascending dose Phase 1a randomized, double-blind, placebo-controlled study in healthy volunteers (Part B), and a Phase 1b open-label study in subjects with CF (Part C) to assess the safety, tolerability, PK, and preliminary efficacy of ABCI. Subjects will be evaluated for eligibility during Screening within 30 days prior to Day 1 (Randomization; Visit 3). In Parts A and B, eligible healthy volunteers may be enrolled in the study and randomly allocated to treatment with ABCI or placebo as described below. In Part C, eligible subjects with CF may be enrolled in the study and receive treatment with ABCI as described below. Approximately 72 healthy subjects total will be randomized to 9 cohorts (48 subjects in 6 cohorts in Part A, 24 subjects in 3 cohorts in Part B) and approximately 20 subjects with CF will receive the medium dose (2 sentinel subjects) or high dose (up to 18 subjects) of ABCI in Part C.
Cystic fibrosis (CF) is the most common severe autosomal recessive genetic disease in Caucasians. The CFTR (cystic fibrosis transmembrane regulator) gene, which encodes the chloride channel of the epithelial cell membrane, is responsible for the development of the disease. Respiratory physiotherapy, especially bronchial drainage is one of the basic elements of comprehensive management in patients with CF. Among the many procedures used in CF drainage physiotherapy, the most commonly include these using positive expiratory pressure (PEP) and oscillating positive expiratory pressure (OPEP). The aim of the study is to assess the efficacy of the usage of selected PEP and OPEP devices in bronchial drainage in cystic fibrosis patients during exacerbation of the disease.
