A Low Interventional Study to Monitor Activity Using Wearable Sensors in Duchenne Muscular Dystrophy...
Duchenne Muscular Dystrophy (DMD)The purpose of this low interventional study is to collect data on everyday movement in boys with Duchenne muscular dystrophy (DMD) using wearable activity sensors. The activity sensors could provide useful information beyond what is currently collected by functional (movement, strength) assessments in clinic. This information can help with the understanding of the impact of DMD, and perhaps with how possible treatments can affect this impact.
Evaluation of Muscle miRNA as Biomarkers in Dystrophinopathies
Muscular DystrophiesBecker Muscular Dystrophy1 moreDuchenne 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.
Pro-inflammatory Cytokines in Facioscapulohumeral Muscular Dystrophy (CYTOKINE-FSH)
Muscular DystrophiesThe facial-glenohumeral muscular dystrophy type 1 (DMFSH1) is characterized by a selective and asymmetrical involvement of the facial muscles, the shoulder girdle and the anterolateral lodge legs. Genetically, the disease is transmitted in an autosomal dominant manner and is caused by a pathogen contraction of repeat units (UR) say D4Z4 localized to the telomeric portion of chromosome 4qA. The loss of UR causes hypomethylation of DNA and chromatin relaxation of the region that lead to inappropriate expression of DUX4 retrogene highly toxic. The inappropriate expression induces a T cell reaction inflammatory response that participate and increase muscle damage. In favor of this hypothesis, several muscle MRI studies have shown that atrophy and fibro-adipose degeneration (hyper signal in T1) were preceded by the appearance of muscle inflammation (hyper signal T2STIR) confirmed on histologically and dysregulation of genes involved in adaptive and innate immunity. scientific hypothesis and potential benefits: the investigateur hypothesize that in patients of DMFSH1, the immune system cells may participate in the pathophysiology of the disease through changes in serum secretion of one or more cytokines and / or a modification of the response of inflammatory cells in some cell damage stimuli. Design: this is a single-center pilot study, interventional. In this study, the investigator will assay the serum cytokines and changes in peripheral blood cells of the expression of cytokines in response to some stimuli in 20 patients with Type 1 DMFSH genetically confirmed at an intermediate stage of clinical disease (kept walking, but at least one muscle of lower limbs reached) and compare with controls from the CYTOKINAGE study. The investigator will also carry patients clinical testing (MMT sum score) and functional (6minute test march MFM) and a MRI not injected whole body (T1 sequences + and T2STIR) to study the relationship between these parameters and secretion cytokines or serum in response to certain stimuli Main objective: to compare serum levels of IL-6 in patients with DMFSH and controls.
The Effect of Telerehabilitation of Patients With Duchenne Muscular Dystrophy
Duchenne Muscular DystrophyThe 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
Effect of Aerobic Training in Patients With Oculopharyngeal Muscular Dystrophy
Oculopharyngeal Muscular DystrophyThe investigators want to investigate if patients with Oculopharyngeal Muscular Dystrophy can improve fitness by home-training on a cycle ergometer 30 minute, 3 times a week for 10 weeks. Participants will be evaluated on maximal oxygen consumption and maximal workload measured by an incremental test at baseline and at the end of the exercise period.
Relationship Between PFTs and Pdi in DMD
Duchenne Muscular DystrophyA cross-sectional study to explore the relationship between clinically assessed pulmonary function test (PFT) measures and transdiaphragmatic (Pdi) measures in Duchenne muscular dystrophy (DMD) as well as to explore the relationship between sniff nasal inspiratory pressure (SNIP) and transdiaphragmatic (Pdi) measures in Duchenne muscular dystrophy.
Postural and Anthropometric Properties of Foot and Ankle of Patients With DMD
Duchenne Muscular DystrophyAmbulation Difficulty3 moreIntroduction: Progressive muscle weakness, joint contractures and body alignment disorders seen in patients with Duchenne Muscular Dystrophy (DMD) adversely affect the foot structure of the patients. Objective: The aim of this study is to examine the relationship between foot posture, performance and ambulation in patients with DMD. Method: The patient with ambulatory DMD will be included in the study. The foot postures of the patients will be evaluated with the Foot Posture Index. Relationships between the Foot Posture Index and performance tests (6 minute walk test, timed performance tests (10m walking, Gower's, climb/descend 4 stair)) and the North Star Ambulation Evaluation, an ambulation evaluation, will be examined.
