Filter by:Long-term outcome in late-onset Pompe disease treated beyond 36 months (ATBIG-Pompe-Study), a multicenter, multinational, longitudinal, non-interventional observational study in subjects, at least 8 years old, diagnosed with late-onset Pompe disease retrospectively and prospectively collects data to understand clinical progression in terms of muscle and respiratory function, and clinical symptomology treated with alglucosidase alfa more than 36 months in 100 subjects.
This study is being done to test the effects of respiratory muscle training (RMT) in patients with late-onset Pompe Disease (LOPD) who have weakness of their breathing muscles. The results of this study will help design future research studies about RMT in LOPD. The goals of this study are to decide if sham-RMT is a useful control condition for RMT and to choose the best ways to measure the health benefits of RMT in LOPD.
Primary Objective: To determine the effect of avalglucosidase alfa treatment on respiratory muscle strength measured by percent (%) predicted forced vital capacity (FVC) in the upright position, as compared to alglucosidase alfa. Secondary Objective: To determine the safety and effect of avalglucosidase alfa treatment on functional endurance (6-minute walk test, inspiratory muscle strength (maximum inspiratory pressure), expiratory muscle strength (maximum expiratory pressure), lower extremity muscle strength (hand-held dynamometry), motor function (Quick Motor Function Test), and health-related quality of life (Short Form-12).
This purpose of this study is to determine if tongue strength and tongue ultrasound measurements differentiates patients with untreated late-onset Pompe Disease (LOPD) from patients with acquires/hereditary myopathies or neuropathies. It is hypothesized that abnormalities in tongue function and structure in patients with LOPD may be useful in discriminating this condition from others that have similar presentations.
To investigate the motor development, motor function and electrodiagnostics presentation in IOPD under ERT.
A breach of respiratory function may be one of the elements more or less early or predominant clinical picture of neuromuscular diseases. It is considered that the obstructive syndromes represent 64% and restrictive or mixed syndromes 36% of chronic respiratory insufficiency, approximately 7% due to a neuromuscular disease. The frequency and type of impairment are dependent on the underlying pathology. The neuromuscular restrictive respiratory failure (IRR) remains partially unknown pulmonologists, especially because the signs of muscle weakness are sometimes difficult to detect. However, respiratory diseases are a major concern in neuromuscular diseases because they can have an impact both on sleep (not sleep, ...) on the daily activities (breathlessness on exertion, dyspnea) and thereby alter the quality of life of patients. Moreover, they represent a significant morbidity and mortality factor. Chest tightness may in some cases reveal the disease and thus constitute the chief complaint of a patient with a neuromuscular disease. In late-onset Pompe disease, lung disease is the predominant clinical symptoms in about 30% of patients. An algorithm was developed to guide practitioners and help them in their diagnostic approach to the cause of the IRR (diagnostic algorithm ATS / ERS 2005). However, this algorithm does not allow precise identification of the neuromuscular causes. At the patient level, this can have an impact by extending the time before placing a diagnosis. In Pompe disease, the average time to diagnosis reached 7.9 years. However, there are for this disease a simple and rapid diagnostic test. Therefore, a greater awareness of practitioners with regard to the particular Pompe disease and neuromuscular diseases in general may be beneficial to patients. This study aims to: i) awareness pulmonologists to the possibility of neuromuscular an IRR. ii) characterize the frequency of neuromuscular origin of IRR in a broad population of patients with concomitant signs muscle weakness. iii) reduce the time to diagnosis by directing patients to neuromuscular reference center early.
Study Objectives: 1. Determine the correlation between quantitative muscle ultrasound (QMUS), electrical impedance myography (EIM) and currently accepted measures of physical function. 2. Determine the reliability of EIM measures performed in the home through use of a hand held device. 3. Determine if QMUS and EIM can detect pre-clinical changes in Pompe disease.
The aim of the project is to develop new Magnetic Resonance (MR) imaging techniques for better diagnosis and monitoring of patients with muscular disorders. Muscle quality in patients with Late Onset Pompe Disease (Acid Maltase Deficiency type 2) and in patients with Myotonica Dystrophy will be evaluated, by determining muscle strength in relation to muscle size and muscle strength in relations to fat-muscle ratio.
This study is an international, multi-center, study of Pompe disease patients that are currently receiving enzyme-replacement therapy (ERT). The purpose of this study is to find out if the co-administration of investigational new drugs ATB200 and AT2221 is safe in adults with Pompe disease.
The purpose of this research study is to determine if exercise will help improve muscle strength, endurance, and quality of life in individuals with Pompe disease. This is a research study to further define the outcome of patients with Pompe disease treated with a combined diet and exercise therapy.
