Around 20% of patients with myasthenia gravis are acetylcholine receptor antibody negative; muscle-specific tyrosine kinase antibodies (MuSK) were identified as the cause of myasthenia gravis in 30% to 40% of these cases. Anti MuSK myasthenia gravis is associated with specific clinical phenotypes. One is a bulbar form with fewer ocular symptoms. Others show an isolated head drop or symptoms indistinguishable from acetylcholine receptor-positive myasthenia gravis. These patients usually respond well to immunosuppressive therapy, but not as well to cholinesterase inhibitors. Other antibodies associated with myasthenia gravis, including low-density lipoprotein receptor-related protein 4, are discussed.

Introduction: Eculizumab is a C5 complement inhibitor approved by the FDA for the targeted treatment of four rare diseases, paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), generalized myasthenia gravis (gMG), and aquaporin-4 immunoglobulin G-positive optic neuromyelitis optica spectrum disorders (AQP4-IgG+NMOSD). The current study was conducted to assess real-world adverse events (AEs) associated with eculizumab through data mining of the FDA Adverse Event Reporting System (FAERS).

Methods: Disproportionality analyses, including Reporting Ratio Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-Item Gamma Poisson Shrinker (MGPS) algorithms were used to quantify the signals of eculizumab-associated AEs.

Background: Anti-NMDA receptor encephalitis is an autoimmune, antibody-mediated inflammatory disease of the brain characterized by the presence of IgG antibodies targeting the excitatory N-methyl-D-aspartate receptor (NMDAR). Previous research has established that the neonatal Fc receptor (FcRn) regulates the transport and circulation of immunoglobulins (IgG). Efgartigimod, an FcRn antagonist, has been shown to enhance patient outcomes by promoting IgG clearance, and it has exhibited substantial clinical efficacy and tolerability in the treatment of myasthenia gravis.

Myasthenia gravis (MG) is an autoimmune disorder involving complex interactions between genetic and environmental factors. Genome-wide association studies (GWAS), transcriptome-wide association studies (TWAS), and other methods have identified multiple novel susceptibility loci and genes, providing crucial insights into the genetic etiology of MG. Moreover, the pivotal roles of epigenetic mechanisms, such as DNA methylation, histone modifications, and non-coding RNAs, in the pathogenesis of MG are gradually being unveiled.

Hyperthyroidism is linked to several muscle disorders, including thyrotoxic myopathy, myasthenia gravis, and periodic paralysis. Thyrotoxic periodic paralysis (TPP) is a rare and potentially life-threatening neuromuscular condition that predominantly affects Asian males and is characterized by muscle weakness, hypokalemia, and thyrotoxicosis. Treatment involves potassium supplementation, and beta-blockers.
