Real-life pharmacovigilance identifies unreported side effects of eculizumab and alglucosidase alpha

Two Chinese teams looked at the real-life side-effects of eculizumab in the treatment of myasthenia and alglucosidase alfa in the treatment of Pompe disease. Analysis of data from the FDA’s pharmacovigilance system, FAERS (FDA Adverse Event Reporting System), revealed : 46,316 side-effect reports for eculizumab between 2007 and 2023, grouped under 461 preferred terms; 4,326 … [Read more]

Two molecules with therapeutic potential identified in LGMD R2

A collaboration involving I-Stem, Genethon and the Institute of Myology carried out a high-throughput screening of 2,239 drugs already approved for other diseases and other bioactive compounds on immortalised myoblast models of limb-girdle muscular dystrophy type R2 (LGMD R2) carrying the L1341P missense mutation in the DYSF gene or in muscle fibres from dysferlin-deficient mice: … [Read more]

A therapeutic advance in myopathies related to the RYR1 gene

Swiss researchers have undertaken preclinical work to pharmacologically treat one of the forms of myopathy linked to the ryanodine receptor type 1 (RYR1) : the model used for this research was a composite heterozygous mouse for two pathogenic variants of the RYR1 gene (p.Q1970fsX16 and p.A4329D) these mice were treated for 15 weeks with 0.05 … [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]

Tracking and preventing possible myocardial complications: a major challenge for DMD gene therapy

As treatment with delandistrogene moxeparvovec begins to be widely prescribed in the United States for Duchenne muscular dystrophy (DMD), American experts have come together to issue recommendations aimed at better identifying and preventing the deleterious effects of this gene therapy (GT) on the heart: cases of myocarditis induced by TG remain exceptional but can be … [Read more]

FSHD combined with genuine myositis: an intriguing association

A French study involving clinicians from the Institute of Myology reports several new and disturbing cases of patients with two co-existing neuromuscular pathologies: firstly, facioscapulohumeral muscular dystrophy (FSHD), proven by molecular biology, and secondly, myositis authenticated by the presence of specific autoantibodies, of the 5 cases of this type identified in the myositis database of … [Read more]

An alternative method for injecting nusinersen intrathecally

Spanish clinicians report their experience with an unconventional injection route in the treatment of SMN1-related proximal spinal muscular atrophy (SMA) with nusinersen : six patients with SMA, including five with type II and one with type III, benefited from this treatment due to the impossibility of using the lumbar route, Five were over 18 years … [Read more]
