Filter by:This study evaluates the effects of a low-intensity blood-flow restricted exerciser protocol on patient reported physical function, in patients with sporadic inclusion body myositis. The study is designed as a parallel group randomized controlled trial with a treatment group and a control group.
This project will bring together a multidisciplinary team of pediatric rheumatologists, neurologists, metabolic geneticists and exercise physiologists to determine the effect of creatine (CR) supplementation on muscle function and muscle metabolism in children with Dermatomyositis (DM). The investigators propose using well-established exercise testing techniques as well as new, powerful exercise imaging protocols in order to better delineate the effects of CR on muscle pathophysiology in a non-invasive way. Evidence from this study will provide information regarding the effect of creatine supplementation on muscle function in DM. Improvements in muscle function and fatigue through CR use may also contribute to an improvement in quality of life and have significant clinical implications for the treatment of children with DM.
This study is an open-label, long-term study for those patients who participated in the prior proof-of-concept protocol, in which the preliminary efficacy for BYM338 in patients with sIBM was demonstrated after a single 30 mg/kg i.v. dose of BYM338. This study is designed to confirm the efficacy, safety and tolerability of BYM338 in sIBM with long-term dosing. However due to lack of efficacy in patients with sIBM, the study was terminated early.
The purpose of this research study is to investigate how and why the loss of muscle mass occurs with aging. Tissue collected from young subjects will be compared to previously collected tissue from elderly subjects, as well as previously collected data on muscle function/mass to further investigate cellular and molecular pathways that have recently been shown to be important for the aging process in muscle. The Principal Investigator (PI) and the study team will look for specific proteins (called biomarkers) that can be present in the muscle tissue in various amounts in different individuals. This study will increase the investigators understanding of the processes of muscle atrophy (loss of mass) and functional loss at older age and will help to find new treatments and interventions aimed at improving the quality of life and independence of America's rapidly expanding elderly population.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
This study evaluated the efficacy, safety and tolerability of multiple doses of bimagrumab/BYM338 vs placebo, when administered intravenously (i.v.), on physical function, muscle strength, and mobility in patients with sporadic inclusion body myositis (sIBM).
Interstitial lung disease (ILD) is characterised by inflammation and scarring of the lung and is the leading cause of death in patients with systemic sclerosis, and contributes significantly to morbidity and mortality in many other connective tissue diseases (CTDs) such as polymyositis/dermatomyositis and mixed connective tissue disease. When ILD is extensive and/or progressive, immunosuppressive medication is often required to stabilize lung disease and alleviate symptoms. Current standard care for CTD associated ILD is extrapolated from studies performed in individuals with systemic sclerosis and comprises low dose corticosteroids and intravenous cyclophosphamide followed by oral azathioprine. In some individuals even this intensive immunosuppression is insufficient to prevent deterioration, and in a significant minority of affected individuals this results in respiratory failure and death. Rituximab has recently been reported as an effective 'rescue therapy' for stabilizing and even improving ILD in this patient group. Based on observations gained from this experience, the investigators believe that rituximab is a potential important alternative to current best therapy for this patient group. This study has therefore been initiated to evaluate the efficacy of rituximab (compared with standard therapy) in patients with progressive CTD related ILD.
The objective of the proposed study is to evaluate the clinical utility of muscle ultrasonography for improving the diagnostic yield and safety of core muscle biopsy. Our facility currently uses core (needle) biopsy to obtain muscle samples in patients 18 years old or older. Currently, there is no imaging tool used to guide the actual biopsy. As muscle biopsy is an invasive and potentially painful procedure, improving the diagnostic yield of this test is important.
Background: - Myositis is a rare disease in which the body s immune cells attack the muscle tissue. It can cause muscle weakness, swelling, and pain. It can develop in people with no history of muscle problems. Environmental exposures may determine who develops myositis. Genes may also affect development of the disease. - Some people who serve in the military develop myositis. However, other military personnel do not. Researchers want to compare military personnel with and without myositis. They will look for common factors that might have led to the disease. Objectives: - To study environmental risk factors for myositis in military personnel. Eligibility: - Military personnel who developed myositis during their period of service. - Healthy military personnel who do not have myositis or another autoimmune disease. Design: - Participants will have a physical exam and medical history. - Participants will fill out forms about environmental exposures, particularly while in the military. The questions will ask about past infections, vaccines and medications, and personal habits. They will also ask about participants occupations during military service and their deployments. - Participants will also provide blood samples for study. - No treatment will be provided as part of this study.
A prospective observational study to determine the effectiveness of magnetic resonance (MR) imaging in the diagnosis and monitoring of idiopathic myopathy in adult humans.
