Abstract:
Myasthenia gravis (MG) is a rare autoimmune disease of skeletal muscle endplates. MG subgroup is relevant for comorbidity, but usually not accounted for. MG patients have an increased risk for complicating autoimmune diseases, most commonly autoimmune thyroid disease, systemic lupus erythematosus and rheumatoid arthritis. In this review, we present concomitant autoimmune disorders associated with the different MG subgroups, and show how this influences treatment and prognosis. Concomitant MG should always be considered in patients with an autoimmune disorder and developing new neuromuscular weakness, fatigue or respiratory failure. When a second autoimmune disorder is suspected, MG should be included as a differential diagnosis.
Insights
Myasthenia gravis (MG) patients often have other autoimmune diseases, impacting treatment and outcomes. Recognizing these comorbidities is crucial for accurate diagnosis and management of MG.
Area of Science:
- Neurology
- Immunology
- Autoimmune Diseases
Background:
- Myasthenia gravis (MG) is a rare autoimmune disorder affecting neuromuscular junctions.
- Comorbidities in MG are often overlooked but significantly influence patient outcomes.
- MG patients exhibit a higher prevalence of other autoimmune conditions.
Purpose of the Study:
- To review concomitant autoimmune disorders associated with different MG subgroups.
- To analyze the impact of these comorbidities on MG treatment and prognosis.
- To emphasize the importance of considering MG in patients with other autoimmune diseases.
Main Methods:
- Literature review of studies on MG and associated autoimmune diseases.
- Analysis of comorbidity data across various MG subgroups.
- Synthesis of information on diagnostic and therapeutic implications.
Main Results:
- Specific MG subgroups are linked to distinct patterns of autoimmune comorbidities.
- Presence of comorbidities affects treatment strategies and patient prognosis.
- Autoimmune thyroid disease, lupus erythematosus, and rheumatoid arthritis are common co-occurring conditions.
Conclusions:
- Concomitant autoimmune disorders are frequent in MG and require careful consideration.
- MG should be suspected in autoimmune patients presenting with neuromuscular symptoms.
- Integrated management approaches are necessary for patients with coexisting autoimmune conditions.

01:26Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
