RSS feedVa-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]
A severe form of myopathy linked to HNRNPA1 is possible in children
The case of a little girl has overturned the reputation of adult diseases with phenotypes linked to mutations in the HNRNPA1 gene (amyotrophic lateral sclerosis, hereditary myopathy with bordered vacuoles associated with Paget’s disease or distal myopathy with bordered vacuoles): between the ages of 3 and 5, she developed generalised muscle weakness and atrophy affecting … [Read more]
Gene therapies and liver toxicity: an update
French and Belgian hepatologists from the Association Française pour l’Etude du Foie (AFEF) (French Association for the Study of the Liver) have taken stock of what is known about the liver toxicity observed with certain gene therapies used in particular for hereditary diseases: a fairly exhaustive inventory of gene therapy products and the diseases concerned … [Read more]
A partial epidemiology of neuromuscular diseases in the Netherlands
Dutch researchers have carried out a major epidemiological study to determine the prevalence and incidence of the main neuromuscular diseases in their country: incidence was calculated using health data from two registers, one supplied by the network of neuromuscular reference centres (CRAMP register) and the other maintained by the Dutch neuromuscular patient association, using a … [Read more]
