DMD: ventilation, even invasive, does not deteriorate the quality of life

Patients with Duchenne muscular dystrophy (DMD) have seen their life expectancy increase substantially in recent years. Early detection and management of respiratory complications have a lot to do with it. A classic distinction is made between invasive ventilation (IV) on a tracheostomy tube, and non-invasive ventilation (NIV), the latter being most often intermittent. In an … [Read more]

Bioengineering design of a new functional motor unit platform to study neuromuscular interaction

In many neurodegenerative and muscle disorders, as well as the loss of innervation seen in sarcopenia, improper reinnervation of muscle and dysfunction of the motor unit (MU) are found, two key pathogenic features. In vivo studies of MU are limited due to the difficulties in isolating and extracting functional motor units, so there is a … [Read more]

North American study supports the hypothesis of a genetic background predisposing to autoimmune diseases in general, and myasthenia gravis in particular

Myasthenia gravis results from the production of autoantibodies directed against the neuromuscular junction. Like other dysimmune diseases, it may have a genetic component. A recent retrospective study corroborates this hypothesis. It involved 1,032 patients with myasthenia gravis with anti-acetylcholine receptor (anti-RACh) autoantibodies followed in 14 healthcare facilities in North America. Published in September 2020, its … [Read more]

Mosaic mutations in the ACTA1 gene causing early and asymmetric muscle deficits

Congenital myopathies constitute a very heterogeneous group of neuromuscular diseases both clinically and genetically. They are related to the presence of intrinsic lesions or the accumulation of inclusions inside the muscle fiber. Classically described as responsible for global hypotonia and little or no progressive, when the critical period of the first days or months of … [Read more]

The natural history of type III SMA becomes clearer

SMA is caused by the lack of the SMN protein. This degenerative disease of the motor neuron results in paralysis of very varying onset and severity. There are four types, from most severe (type 0) to the mildest (type IV), depending on the age of onset of the disease, the best motor function achieved. In … [Read more]

SRK-015 could be a additional treatment to therapies targeting SMN

Preliminary results at 6 months of the TOPAZ trial evaluating SRK-015 – a myostatin inhibitor – in 48 participants with type II and III SMA have just been communicated: SRK-015 was well tolerated and improves participants’ motor function with a dose-dependent effect.   TOPAZ trial This trial takes place in the United States and Europe … [Read more]

The 249th ENMC workshop was focused on brain dystrophin and cognitive disorders in DMD

The absence of one of these forms of dystrophin in children and adults with Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD), causes varying cognitive, behavioural and communication disorders. Approximately 50% of boys with DMD suffer from these problems, and a slightly smaller percentage of those with BMD. These disorders are no detected sufficiently … [Read more]

Innovation for the non-invasive assessment of the diaphragm – Interview with T. Poulard and D. Bachasson

Thomas Poulard* and Damien Bachasson** from the Neuromuscular Physiology and Evaluation Laboratory headed by Jean-Yves Hogrel, have just published, in the Journal of Physiology, the results of a study*** to develop an ultrafast ultrasound sequence making it possible to “film” diaphragm performance during cervical magnetic stimulation (CMS) of the phrenic nerves in healthy subjects. What are the … [Read more]
