Filter by:Background: Myotonic dystrophy lead to highly heterogeneous, multisystemic symptoms including myotonia, progressive muscle weakness, cardiac conduction defects, cataract, metabolic dysfunction, and excessive daytime somnolence. This last symptom is related to respiratory failure and/or to involvement of the central nervous system. However the metabolic disturbances could contribute to it. From the respiratory point of view this disease is characterised by the progressive appearance of respiratory failure of muscular origin but mainly associated with a defect in the central respiratory drive. The treatment for this hypoventilation is non-invasive ventilation (NIV). It is not currently absolutely clear as to the best choice of criteria to judge long term effectiveness of NIV. The most usual criteria are normalisation of daytime blood gases, diminution of respiratory work, improvement in daytime symptoms and improvement in sleep structure. Other criteria are currently little studied, for instance the contribution of the interaction between alveolar hypoventilation and oxygen desaturation during the night and biological deficiencies such as systemic inflammation, glucose intolerance or insulin resistance. Likewise there is little information about the interaction between alveolar hypoventilation and endothelial dysfunction and arterial stiffness both being accurate predictive factors for cardiovascular risks. Aim: to evaluate the impact of NIV on endothelial dysfunction in patients with myotonic dystrophy. The secondary objectives are to assess the impact of NIV on systemic inflammation, arterial stiffness, insulin-resistance, quality of sleep, and daytime vigilance in these patients. Methods: Patients with chronic alveolar hypoventilation already treated by long term NIV will be included. They will have an initial check-up (Visit 1), then will interrupt NIV treatment for four weeks (Visit 2), and then return to NIV treatment. The last check-up will be done four weeks after NIV resumption (Visit3). Expected results: It is expected that NIV withdrawal will results in a deterioration of cardio-vascular parameters (endothelial function and arterial stiffness), metabolic parameters (insulin-resistance and systemic inflammation), quality of sleep and daytime vigilance. Return to NIV treatment may show an improvement of these parameters with a basal state recovery.
This is a prospective multicentric Italian study to evaluate the arrhythmic risk in myotonic dystrophy type 1.
Myotonic dystrophy (DM) and facioscapulohumeral muscular dystrophy (FSHD) are inherited disorders characterized by progressive muscle weakness and loss of muscle tissue. The purpose of this registry is to connect people with DM or FSHD with researchers studying these diseases. The registry will offer individuals with DM and FSHD an opportunity to participate in research that focuses of their diseases. The registry will also help scientists to accomplish research on DM and FSHD and to distribute their findings to patients and care providers.
