Myasthenia gravis (MG) is an acquired autoimmune disease affecting the postsynaptic membrane of neuromuscular junctions and characterized by antibody-mediated T cell dependence and complement involvement. Cholinesterase inhibitors (e.g., pyridostigmine bromide), glucocorticoids, and azathioprine are currently recommended as first-line treatments for MG, though they have limitations, including potential toxicity and ineffectiveness in patients with refractory MG. In recent years, owing to an increasing understanding of MG pathogenesis the development and execution of clinical trials with novel biologics, including monoclonal antibodies (mAbs) that have demonstrated higher safety and more specificity, provide new opportunities for the treatment of MG. In this article, we review recent advances in MG pathogenesis and the mAbs that have been used for target-specific MG therapy.

Concurrent myasthenia gravis and neuromyelitis optica spectrum disorder: a rare intersection of autoimmune pathologies.
BMJ Case Rep

This case report describes a woman in her 50s with a rare coexistence of neuromyelitis optica spectrum disorder (NMOSD) and myasthenia gravis (MG), highlighting the diagnostic challenges and therapeutic considerations. Initially diagnosed with acetylcholine receptor antibody-positive MG, she later developed progressive visual impairment, leading to a diagnosis of NMOSD. Rituximab treatment was effective in managing both conditions, demonstrating the benefits of targeted therapies in reducing complications related to polypharmacy.

Background: Therapeutic apheresis (TA) are promising treatment option for neuroimmunological disorders. In paediatrics, the available data is limited, particularly for the use of IA. The aim of this study was to analyse the use of PE and IA in children and adolescents, with emphasis on outcome and neurological course after treatment as well as the safety of the two modalities.

Immune checkpoint inhibitors (ICIs), such as pembrolizumab, have revolutionized cancer treatment by enhancing the immune system's response to malignancies. However, these therapies are associated with immune-related adverse events (irAEs), including neuromuscular complications such as myasthenia gravis, myositis, and myocarditis. We describe two male patients, aged 67 and 68, with small cell and non-small cell lung cancers, who developed progressive neuromuscular symptoms, including ptosis, diplopia, and generalized weakness, after receiving pembrolizumab.

This is an unusual case of voltage gated calcium channel (VGCC) antibodies leading to two distinct and chronologically separated neurologic syndromes without the presence of an underlying neoplasm. Lambert Eaton Myasthenic Syndrome (LEMS) presented five years prior to cerebellar ataxia. Both LEMS and cerebellar ataxia were responsive to treatment, but not the same therapy.

Parvovirus B19 (B19V) is a human pathogen from the Parvoviridae family that primarily targets and replicates in erythroid progenitor cells (EPCs). While its symptoms are typically self-limiting in healthy individuals, B19V can cause or exacerbate autoimmune diseases in vulnerable patients. This review integrates the involvement of B19V in the development and worsening of several autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), hematological disorders (thalassemia, anemia, and thrombocytopenia), vasculitis, antiphospholipid syndrome (APS), dermatological disease (systemic sclerosis, psoriasis), autoimmune thyroid disease, myocarditis, and myasthenia gravis, and autoinflammatory disease of adult-onset Still's disease (AOSD).
