The pooled prevalence of COVID-19 infection in myasthenia gravis (MG) patients is 2%. This systematic review and meta-analysis analyzed 18 studies to determine COVID-19 infection rates in individuals with MG.
Area of Science:
- Neurology
- Infectious Diseases
- Autoimmune Disorders
Background:
- Myasthenia gravis (MG) is an autoimmune neuromuscular junction disorder.
- COVID-19 infection rates in MG patients vary across studies.
- Understanding COVID-19 prevalence in MG is crucial for patient management.
Purpose of the Study:
- To estimate the pooled prevalence of COVID-19 infection in individuals with myasthenia gravis.
- To synthesize existing research on COVID-19 in MG patients.
Main Methods:
- Systematic literature search of PubMed, Scopus, EMBASE, Web of Science, Google Scholar, and gray literature up to October 2021.
- Inclusion of 18 articles after removing duplicates from an initial 253.
- Data extraction included participant numbers, MG patient counts, symptoms, hospitalization, and mortality.
Main Results:
- The pooled prevalence of COVID-19 infection among MG patients was 2% (95% CI, 1%-3%).
- Hospitalization prevalence among infected MG patients was 43% (95% CI, 26%-60%).
- MG exacerbation prevalence was 33% (95% CI, 20%-46%).
Conclusions:
- The pooled prevalence of COVID-19 infection in individuals with myasthenia gravis is 2%.
- A significant proportion of MG patients with COVID-19 experienced hospitalization and disease exacerbation.

Musculoskeletal disorders
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...
Chemical 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...
