Filter by:Mitochondrial myopathies are a multisystemic group of disorders that are characterized by a wide range of biochemical and genetic mitochondrial defects and variable modes of inheritance. Currently there are no effective treatments for this disease. Despite the heterogeneous myopathy phenotypes, a unifying feature of mitochondrial myopathies is that the pathogenic mtDNA mutations and/or nuclear mutations of the electron transport chain invariably lead to dysfunctional mitochondrial respiration. This reduction in mitochondrial respiration leads to a reduced ability to produce cellular adenosine triphosphate (ATP), often resulting in muscle weakness, exercise intolerance, and fatigue in patients with mitochondrial myopathies. RTA 408 is a potent activator of Nrf2 and inhibitor of NF κB (nuclear factor kappa-light-chain-enhancer of activated B cells), and thus induces an antioxidant and anti-inflammatory phenotype. Several lines of evidence suggest that Nrf2 activation can increase mitochondrial respiration and biogenesis. Collectively, available data suggest that the ability of RTA 408 to activate Nrf2 and induce its target genes could potentially improve muscle function, oxidative phosphorylation, antioxidant capacity, and mitochondrial biogenesis in patients with mitochondrial myopathies. This study will be a randomized, placebo-controlled, double-blind, dose-escalation study to evaluate the safety of omaveloxolone (RTA 408) at various doses in patients with mitochondrial myopathies.
This retrospective medical chart review (RECENSUS) of approximately 100 XLMTM patients (with a goal to obtain 50 deceased and 20 living records) will provide further knowledge about the clinical manifestations and recorded medical management of XLMTM and potentially inform the design of future therapeutic intervention studies.
The investigators wish to investigate fat and sugar metabolism during exercise with and without L-carnitine supplementation in patients with carnitine transporter deficiency (CTD). Patients with CTD have low plasma- and muscle concentrations of carnitine, which is believed to lead to an impaired fat oxidation. Presently there is no cure available for these patients, but daily intake of L-carnitine has been shown to limit the amount of symptoms. Little is known about the metabolism during exercise and the pathophysiological mechanisms causing the symptoms. Studying the fat and sugar metabolism in CTD patients will contribute to the understanding of the role of the carnitine transporter in the development of symptoms in these patients. Furthermore, knowledge about the fat and sugar metabolism in these patients can increase the understanding of the role of the carnitine transporter in the metabolism healthy persons. The investigators have included 8 patients with genetically verified CTD in the study and a group of 10 age- and sex-matched controls. Subjects will perform a 1h cycling test, exercising at a moderate intensity. By measuring the expiration of carbon dioxide (CO2) and consumption of oxygen (O2), the investigators can determine the total fatty acid and carbohydrate oxidation during cycling. At the same time the investigators will measure the patients' whole body palmitate (fat) and glucose (sugar) oxidation rates using stable isotope technique. The patient group will repeat the cycling test after 4 days without taking their usual L-carnitine treatment. During the treatment break, patients will be admitted to be continuously monitored for heart rhythm disturbances, which is a known but rarely occurring complication to untreated CTD. Since the patients have a defect in their fat metabolism, the investigators expect to find that they have a reduced ability to burn fat, which is the major source of energy during low intensity exercise. It is therefore likely, that the CTD patients will benefit from adjustments in their daily diet, whenever they have to perform physically. By learning about the metabolism of different dietary substances, fat and sugar, these studies can help to improve the treatment in terms of dietary recommendations for CTD patients. This will have a direct impact on the daily life of the patients.
Our aim is to establish multi-center national Egyptian database of information for inherited and acquired neuromuscular diseases in infants and children from 0 to 18 years of age.
Background: -(Degree)ystinosis is an inherited disease. If not treated correctly, it can cause muscle wasting and weakness and kidney damage. Researchers want to learn if growth hormone (GH) can help people with cystinosis. Objective: - To learn if GH treatment can slow or reverse muscle wasting and improve muscle strength in people with cystinosis. Eligibility: - People 18 and older who are already enrolled in protocol 78-HG-0093. Design: - Participants will be admitted to the clinic for eight 3 4 day visits, mostly four months apart. - At each visit, participants will have a history and physical exam and give urine and blood samples. - At month 0 or 13, participants will take tests that will be repeated at their 12- or 25-month visit: - They will have an eye exam, medical consultations, and strength and movement tests. - They will complete questionnaires. - They may have tests of heart activity and lung function. - They will have ultrasound imaging of their arm and hand muscles. They will have a scan of their legs while lying in a magnetic resonance imaging machine (a big metal cylinder). They will have a DEXA bone scan (two X-ray beams measure body composition). They will also swallow barium while X-ray imaging records the throat muscles. - Participants will be randomly assigned to either receive or not receive GH for the first 12 months. Then, at month 13, if they received GH, they will switch for the next 12 months. - Participants will take GH as a daily injection. They will be taught how to give the injections.
This study is evaluating the use of two painless, non-invasive technologies in the assessment of muscle health over time in both healthy volunteers and patients who have diseases that affect the nervous system.
Treatment of Pediatric Subjects with Pearson syndrome
Topical application of BV ointment in patients with Research Diagnostic Criteria/Temporomandibular Disorder 1a and 1b (RDC/TMD) in experimental group, compared to placebo (vaseline) in control group.Application was repeated 3 times a day, during 14 days. Surface electromyography (EMG) was used to measure masseter rest tonus and maximal voluntary contraction tonus. Pain intensity was also analysed in VAS scale. Effectiveness of BV was compared with placebo in masseter myofascial pain in patients with TMD
The purpose of this study is to determine whether active stretching with low frequency currents are more effective than active stretching in the treatment of hamstring shortness syndrome in children.
The primary objective of this study is to obtain long term safety data of ataluren in male participants with nonsense mutation dystrophinopathy (who participated and completed a previous Phase 3 study of ataluren [PTC124-GD-020-DMD {NCT01826487}]) to augment the overall safety database. Screening and baseline procedures are structured to avoid a gap in treatment between the double-blind study (PTC124-GD-020-DMD) and this extension study. This study may be further extended by amendment until either ataluren becomes commercially available or the clinical development of ataluren in duchenne muscular dystrophy (DMD) is discontinued.
