View clinical trials related to Muscular Dystrophy, Duchenne.
Filter by:Background Duchenne and Becker muscular dystrophies are X-linked recessive allelic disorders caused by mutations of the dystrophin gene on chromosome Xp21. Female carriers may pass on the pathogenic variant to their daughters, resulting in a significant number of female carriers of pathogenic DMD variants. There was a large variability in the severity of symptoms with some being asymptomatic and some having severe symptoms. Skewed X-Chromosome Inactivation (XCI) might explain some of this variability. But now, the underlying cause of the large variability in phenotype is therefore uncertain. Aim 1. To describe the change over a 6-year follow-up period in the structure and function of the heart and in function and muscle fat fraction in skeletal muscle of DMD/BMD carriers. 2. To explain the relationship between the XCI and the severity of the disease (phenotype). 3. To compare cardiac affection of female carriers of DMD/BMD to patients with BMD using new cardiac MRI techniques (spectroscopy and Dixon sequences). Methods This study contains three parts: Part 1 is a 6-year follow-up on 53 genetically verified female carriers of pathogenic DMD variants initially investigated in 2016-2018 at Copenhagen Neuromuscular Center, Rigshospitalet (Ethical journal no. H-16035677). In this part, the same 53 females will be investigated with the same measurements as 6 years ago to describe the progression of symptoms. All the follow-up results from this study will be compared to the results from 6 years ago. In Part 2 a muscle biopsy will be taken from 1-3 muscles (see "3.3.3 Description of outcomes) to investigate the XCI. To correlate the XCI to the phenotype, these patients will also undergo a muscle MRI and a Medical Research Council scale score for muscle strength (MRC). In Part 3 The cardiac structure and function in patients with BMD will be investigated using a cardiac MRI to compare the findings with that of female carriers. An MRC will carried out to investigate if the heart affection correlates to the muscle affection. Female carriers can decide whether to participate in Part 1, Part 2, or both. Patient with BMD can only participate in Part 3.
The purpose of this study is to describe the progression of tissular and functional myocardial abnormalities in patients with Duchenne muscular dystrophy using cardiac magnetic resonance imaging and blood biomarkers assays.
The addition of SMA and DMD muscle diseases to newborn screening and premarital carrier screening has been controversial. In this study, researchers aim to measure the awareness level of SMA and DMD muscle diseases of individuals living in Turkey and to obtain information about their attitudes towards newborn and carrier screening and physiotherapy practices. Thus, this study aimed to determine the factors that affect people's views on this subject.
Muscular dystrophies are a heterogenous group of inherited muscular disorders characterized by progressive muscle weakness. Historically, these disorders are difficult to treat. In the last three decades, there is a great progress in molecular and genetic basis of these disorders; early diagnosis is achievable with proper clinical recognition and advanced genetic testing .Duchenne Muscular Dystrophy (DMD) is a neuromuscular muscular X-linked recessive disorders that belong to a group of disorders known as dystrophinopathies. DMD characterized by a progressive degeneration of skeletal muscles, with symptoms that manifest early, at around 3 years, causing loss of ambulation within the 13 years of life, followed by cardiac complication (e.g., dilated cardiomyopathy and arrhythmia) and respiratory disorders, including chronic respiratory failure. The unique medical treatment available is steroid therapy, which appears to prolong walking capacity by at least two years. Thus, besides medical treatment, the physical therapy in multidisciplinary care is imperative for alleviating muscle atrophy, skeletal deformities, and motor function deterioration.
The aim of this study is to investigate the effect of a telerehabilitation approach to patients with Duchenne Muscular Dystrophy and evaluate patients' motor function, parents' anxiety and depression levels before and after the intervention
The ICD-Reality study is a non-commercial, investigator-led, multicenter, prospective, randomized, controlled trial. We aim to determine the effect of CRT-D or CRT-P implantation in non-ischemic cardiomyopathy and heart failure patients. The reason why we initiated this trial is the lack of evidence-based treatment for the significant number of these patients. In these patients, 5-year mortality remains as high as 20% despite recent therapeutic advances. Based on currently available evidence, because of a significant decrease in mortality due to modern pharmacotherapy, it is not certain which of these patients should receive a CRT-P and who should receive a CRT-D. No dedicated and adequately powered trial has addressed this important question. We hypothesize that patients with symptomatic HF, LVEF ≤35%, without left ventricular mid-wall fibrosis on LGE-CMR, will not benefit from CRT-D implantation compared with CRT-P only implantation. If our hypothesis is confirmed, this could provide evidence for the management of these patients with a significant impact on common daily praxis and health care expenditures. We aim to enroll 600 patients in the trial. 924 patients are needed to be screened for these 600 patients to be randomized. Patients with non-ischemic HF visiting an out-patient department and possibly eligible for the trial will have their pharmacotherapy optimized. Patients with a significant amount of fibrosis will be excluded from the study and treated according to local practice with an emphasis on ICD implantation to prevent SCD. After fulfilling all eligibility criteria, including maximally tolerated pharmacotherapy, subjects will be randomized by the physicians who enrolled them in a 1:1 ratio to receive CRT-D or CRT-P implantation. All patients will be followed-up for at least 3 years after the implantation.
