Published: April 2022

Myasthenia gravis (MG) is a rare autoimmune disease mediated by antibodies against components of the neuromuscular junction, particularly the acetylcholine receptor (AChR). The thymus plays a primary role in AChR-MG patients. In early-onset AChR-MG and thymoma-associated MG, an interferon type I (IFN-I) signature is clearly detected in the thymus. The origin of this chronic IFN-I expression in the thymus is not yet defined. IFN-I subtypes are normally produced in response to viral infection. However, genetic diseases called interferonopathies are associated with an aberrant chronic production of IFN-I defined as sterile inflammation. Some systemic autoimmune diseases also share common features with interferonopathies. This review aims to analyze the pathogenic role of IFN-I in these diseases as compared to AChR-MG in order to determine if AChR-MG could be an acquired interferonopathy.

International consensus guidance and Japanese clinical guidelines for myasthenia gravis (MG) recommend achieving minimal manifestations or better status (MM-or-better) as the severity component of the treatment goal. However, the subjective nature of determining MM can result in ambiguity regarding this category in clinical practice and clinical trials. This study analyzed severity metrics in a large number of MG patients to propose criteria for MM-or-better.

Objective: Myasthenia gravis (MG), a low-prevalence autoimmune disorder characterized by clinical heterogeneity and unpredictable disease fluctuations, presents significant risks of acute exacerbations requiring intensive care. These crises contribute substantially to patient morbidity and mortality. This study aimed to develop and validate machine-learning models for predicting intensive care unit (ICU) admission risk among patients with MG-related disease instability.

Programmed cell death-1 (PD-1) inhibitors and programmed cell death ligand 1 (PD-L1) inhibitors are considered effective alternatives for the primary treatment of recurrent metastatic cancers. However, they can induce various adverse events affecting multiple organ systems, potentially diminishing patients' quality of life, and even leading to treatment interruptions. Adverse events related to PD-1/PD-L1 inhibitors differ from those associated with CTLA-4 inhibitors and are more commonly observed in the treatment of solid tumors.

Myasthenia gravis (MG) presents with symptoms that significantly affect patients' daily lives. Long-term MG therapies may lead to substantial side effects, predominantly due to prolonged immune suppression. Sirt6, which plays a vital role in maintaining cellular homeostasis and is recognised for its involvement in cytokine production in immune cells, has not yet been explored in relation to MG.

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.
