Electrophysiological studies are useful in differentiating CMS

Researchers from the Institute of Myology analysed electroneuromyography data from 120 patients with congenital myasthenic syndromes (CMS) and compared them with the results of genetic studies: five distinct profiles could be established from the measurement of CMAPs and repetitive stimulation of three nerves (accessory nerve, radial nerve, deep fibular nerve) at a frequency of 3 … [Read more]

Evolution of scoliosis in SMA type II in absence of modifying treatment

To address the lack of data on the course of scoliosis without treatment that could be used as a benchmark for clinical trials or modifying treatment, an Italian team conducted a retrospective study in 84 people with SMA type II. The mean scoliosis angle was 46°, with those aged seven years or less being significantly … [Read more]

Quantitative muscle imaging enables early detection of degenerative lesions in calpainopathies

German researchers compared quantitative magnetic resonance imaging (MRI) data of a set of muscles from 19 patients with calpainopathy and 19 healthy subjects. These data were then analysed in relation to other clinical and functional parameters for correlation: the study targeted eight muscles of the thigh and seven of the leg; selective involvement of the … [Read more]

Motor plate analysis relevant to the diagnosis of seronegative myasthenia

A Japanese team evaluated the value of studying the motor plate in people who were negative for anti-RACh and anti-MuSK antibodies. Twenty people with symptoms suggestive of myasthenia had a neuromuscular biopsy of the biceps brachii. Five people had complement deposition in the motor plate : .  four of them also had a decrease in … [Read more]

Myasthenia gravis: the role of thymic macrophages is essential

Myasthenia gravis (MG) is a neuromuscular disease related to the deleterious action of autoantibodies directed against elements of the neuromuscular junction, most often against the acetylcholine receptor (AChR) which is located in the postsynaptic region. The thymus plays a key role in this pathology (AChR-MG) and is characterised by an IFN-β-related type I interferon (IFN) … [Read more]

Anti-fibrotic drug therapies in skeletal muscle diseases

Fibrosis is defined as an excessive accumulation of extracellular matrix. It can affect many organs, including the lungs, liver, heart, skin, kidneys and muscles. Muscle fibrosis is the result of a defective regeneration process, unresolved inflammation or chronic damage. Many muscle diseases have a combination of high levels of fibrosis and muscle wasting and weakness. … [Read more]
