Filter by:Longitudinal prospective observational study. This is a 24-month study with the possibility of extending the data time points. Initially baseline, then 12 and 24 months follow up studies will be completed.
Duchenne muscular dystrophy (DMD) , caused by mutations in the DMD gene, is the most common and most severe progressive dystrophy of the child. Although the development is rapidly progressive , there is variability in the severity of the disease between DMD patients that do not correlate with the type of mutations in the DMD gene. There are no easily measurable biomarkers for monitoring the DMD or moderate form of the disease, Becker muscular dystrophy (BMD ) . MicroRNAs (miRNAs) are involved in most cellular processes , and their expression pattern is a signature of the state of a cell . They represent a potential class of diagnostic and prognostic biomarkers. Some are specific for the skeletal myogenesis , and changes in their pattern of expression are associated with muscle diseases including muscular dystrophy. The levels of muscle- specific miRNAs are indeed greatly increased in the serum of DMD and BMD compared to control patients . The main objective of this is to validate the use of serum muscle-derived microRNAs as biomarkers of DMD patients (compared with healthy subjects). Secondary objectives are i) to investigate the relationship between circulating levels of these miRNAs and the severity of the dystrophinopathy (DMD vs BMD) and also the progression of the disease (longitudinal study), ii) to assess the specificity of these markers for dystrophinopathy (comparison with other patients with muscular dystrophy), iii) to test candidate miRNAs recently identified but not yet analyzed in the serum of patients. Clinical data and samples will be recorded at each regular consultation. miRNA levels will be quantified using Real Time Quantitative RT-PCR.
The Duchenne Registry is an online, patient-report registry for individuals with Duchenne and Becker muscular dystrophy and carrier females. The purpose of the Registry is to connect Duchenne and Becker patients with actively recruiting clinical trials and research studies, and to educate patients and families about Duchenne and Becker care and research. At the same time, The Duchenne Registry is a valuable resource for clinicians and researchers in academia and industry, allowing access to de-identified datasets provided by patients and their families-information that is vital to advances in the care and treatment of Duchenne. The Duchenne Registry is a member of the TREAT-NMD Neuromuscular Network.
The purpose of this research study is to determine the potential of magnetic resonance imaging, spectroscopy, and whole body imaging to monitor disease progression and to serve as an objective outcome measure for clinical trials in Muscular Dystrophy (MD). The investigators will compare the muscles of ambulatory or non-ambulatory boys/men with DMD with muscles of healthy individuals of the same age and monitor disease progression in those with DMD over a 5-10 year period. The amount of muscle damage and fat that the investigators measure will also be related to performance in daily activities, such as walking and the loss of muscle strength. In a small group of subjects the investigators will also assess the effect of corticosteroid drugs on the muscle measurements. Additionally, the investigators will map the progression of Becker MD following adults with this rare disease. The primary objective is to conduct a multi-centered study to validate the potential of non-invasive magnetic resonance imaging and magnetic resonance spectroscopy to monitor disease progression and to serve as a noninvasive surrogate outcome measure for clinical trials in DMD and BMD. The secondary objective is to characterize the progressive involvement of the lower extremity, upper extremity, trunk/respiratory muscles in boys/men with DMD and BMD guiding clinical trials.
Data on preventive therapy in Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) affected individuals without cardiac involvement are very limited and currently lacking regard both ACE-inhibitors and Beta-Blockers in Becker Muscular Dystrophy and for the latter even in Duchenne Muscular Dystrophy patients. Thus, the study aim is to compare the efficacy of carvedilol vs ramipril on myocardial tissue properties and heart function, performing CMR and myocardial Ultrasound Tissue Characterisation analysis.
