Screening for rare diseases at birth using molecular biology is becoming a reality in several countries. The Screen4Care project brought together a group of experts including clinicians, biologists and representatives of both patients and industry: from an initial list of 484 actionable genes, the experts defined six selection criteria largely inspired by the Wilson and … [Read more]
MoCo MRF T1-FF: a new approach to accurately assess upper body muscle tissues using NMR despite respiratory motion
Over the last decade, MR Fingerprinting (MRF) has emerged as an effective paradigm for the rapid and simultaneous quantification of several parameters using MRI. This method was adapted in 2020 by the NMR Laboratory – Spectroscopy Laboratory at the Institute of Myology to measure parameters that are interesting biomarkers in neuromuscular disorders: water T1 as an … [Read more]
Myo-Guide: an online tool combining AI and MRI to help diagnose NMDs
An international consortium has developed a web application based on artificial intelligence (machine learning) for the automated diagnosis of neuromuscular diseases using muscle MRI. It can be accessed by anyone on the Myo-Guide platform. To develop it, 34 centres in Europe, America and Asia shared 2,961 muscle MRI scans of patients with 20 different pathologies. Its … [Read more]
Va-C-Nemus reassures on the safety of vaccination against Covid-19 in NMD
Launched in 2021, the Va-C-Nemus national prospective observational study involved 1,020 adults with a neuromuscular disease of genetic or autoimmune origin, 18% of whom were on corticosteroid and/or immunosuppressive therapy, 20% on respiratory assistance and 5% with cardiac involvement. After one year of post-vaccination follow-up : the type and frequency of adverse events were similar … [Read more]
Rising incidence of motor neurone disease in France before the Covid-19 crisis
Using data from the French National Health Data System (SNDS), a French team has carried out a study of changes in the incidence of motor neurone disease between 2010 and 2023. During this period, 30,028 new cases of motor neurone disease were recorded, with an average of 2,145 new cases per year. The crude incidence … [Read more]
Results of a European survey on the management of bone problems in neuromuscular diseases
The partial or total immobility caused by many neuromuscular diseases, whether or not associated with the deleterious effect of corticosteroid therapy, is often the cause of bone problems (osteoporosis, osteopenia, fractures, compression, etc.): The Euro-NMD neuromuscular reference network (ERN) has conducted a double survey on these complications, which are frequently encountered over the long term, … [Read more]
A large proportion of MNM patients in favour of telemedicine, despite some reluctance
A French study collected data from 103 adults with a slowly progressive neuromuscular disease who had been using non-invasive ventilation for at least six months, using questionnaires to gain a better understanding of their feelings and experience of telemedicine for respiratory monitoring. Concerning teleconsultation : 73.8% of patients were in favour, 26.2% opposed. 61.2% of … [Read more]
Checkpoint inhibitors can induce myositis, but more rarely myasthenia gravis
A French study involving several researchers and clinicians from the Institute of Myology has retrospectively demonstrated the toxic effects of checkpoint inhibitors (ICIs), innovative products widely used in oncology: previous studies had reported cases of induced myasthenia or, more frequently, induced myositis, Using the AP-HP data warehouse, 620 records of patients treated in this way … [Read more]
Retrospective study of the Institute of Myology’s muscle biopsies in infants
A retrospective study of 535 muscle biopsies taken over 52 years from infants aged between 0 and 6 months and collected at the Institut de Myologie showed that : 82% of them showed abnormalities specific to a neuromuscular disease; between 1970 and 1999, 11.6% of biopsies (out of 248) were normal, compared with 4% (out … [Read more]
Towards a better understanding of myopathy linked to the DNAJB4 gene
An international consortium of researchers and clinicians report the clinical and biological data of patients diagnosed with DNAJB4-related myopathy: 5 families of distinct and unrelated ethnic origins were included in the study following the discovery of 5 pathogenic variants of the DNAJB4 gene, including three with loss of function, the clinical picture combined spinal rigidity … [Read more]
