Filter by:The purpose of this study is to investigate the effects of mexiletine treatment for 6 months on ambulation, myotonia, muscle function and strength, pain, gastrointestinal functioning, cardiac conduction, and quality of life in myotonic dystrophy type 1 (DM1).
Myotonic dystrophy Type 1 (MD1, Steinert's disease), an autosomal dominant multisystem disease, is of the most common muscular dystrophies in adults, with a European prevalence of 3-15/100 000. The disease course is progressive, associating muscular weakness, wasting and myotonia. Respiratory dysfunction is common, involving a restrictive ventilatory abnormality and alveolar hypoventilation, originating from respiratory muscle weakness. Depending on the degree of impairment of their lung function, the quality of life and the prognosis of MD1 patients may be very variable. However, time course and prevalence of such respiratory function impairment have not been clearly identified. More importantly, factors able to predict poor respiratory outcome have not been defined and therefore early prognosis can not be assessed during the follow-up of these patients. In other neuromuscular disorders, especially Amyotrophic Lateral Sclerosis (ALS), postural spirometry has been recommended to improve the detection of diaphragmatic involvement and some authors have suggested that the supine fall in the forced vital capacity could be used to initiate noninvasive positive pressure ventilation and predicts some respiratory symptoms. In a sample of ambulatory patients with MD1, our study was designed to prospectively achieve two aims: 1) to assess the respective prevalence of a ventilatory restrictive pattern, respiratory muscle weakness, hypoxemia and hypercapnia and 2) to evaluate whether postural changes in lung volumes contribute to sensitize the diagnosis of respiratory weakness and could be used as a predictor of poor respiratory function, including hypoxemia, hypercapnia and restrictive ventilatory disease.
Myotonic dystrophy type 1 (DM1) is the most frequent neuromuscular disease in adults. DM1 patients have an impaired prognosis (mean age of death <60 years) due to cardiac and respiratory complications. Our primary objective was to identify cardiac and respiratory prognostic factors in DM1.
Adult myotonic muscular dystrophy (Steinert's disease) is the most common inherited neuromuscular disorder. Cardiac rhythm disturbances occur frequently in this disease state and may be responsible for up to one-third of deaths. In this study, we intend to evaluate the utility of non-invasive electrocardiographic screening methods and history in predicting serious arrhythmic events.
To investigate the effects of rhIGF-I/rhIGFBP-3 treatment for 24 weeks on endurance, ambulation, cognitive functioning, insulin resistance, lipid levels, muscle function and strength, pain, gastrointestinal functioning, and quality of life endpoints in DM1 patients
The aim of this study is to investigate the safety and feasibility of daily subcutaneous injections of recombinant IGF1 complexed with IGF binding protein 3 (SomatoKine-INSMED) as a treatment for muscle wasting and weakness in myotonic dystrophy type 1.
To test the efficacy and safety of two doses of dehydroepiandrosterone (DHEA) in adults with myotonic dystrophy
OBJECTIVES: I. Examine the interrelationships between muscle wasting (phenotype), the degree of myotonic dystrophy (DM) gene expression (genotype) in patients with DM. II. Characterize the insulin resistance in these patients. III. Assess the glucose uptake in the leg and forearm tissues of these patients. IV. Determine the stability of the DM gene lesion in muscles over a 5-10 year period.
