We investigated outcomes of MG patients infected with SARS\u2010CoV\u20102 to identify risk factors for exacerbation and severe disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective analysis of 39 MG patients with SARS\u2010CoV\u20102 infection from January March 1, 2020 to October 25, 2021 at Emory University. Patients\u2019 records were queried for demographic data, MG history, and COVID\u201019 treatments and hospitalizations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At the time of infection, 8 of 39 were vaccinated, 30 of 39 unvaccinated, and 1 unknown. Average age was 52.6\u2009years. Twenty\u2010seven patients were receiving immunomodulatory treatments at the time of infection. Thirty\u2010five of 39 were symptomatic, 21 were hospitalized, and 7 required ventilations. MG exacerbations occurred in 5 and were treated with therapeutic plasma exchange (n\u2009=\u20091), intravenous immunoglobulin (IVIg) (n\u2009=\u20091), and prednisone taper (n\u2009=\u20095). Four hospitalized patients died from COVID\u2010related lung injuries. No deaths were attributed to MG exacerbation; however, one patient receiving IVIg for MG exacerbation had a pulmonary embolism. There were no deaths in fully vaccinated patients, and only one vaccinated patient was admitted to the intensive care unit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>High rates of COVID\u201019 complications and death were observed in this cohort of MG patients. Some patients with MG and COVID\u201019 also had an exacerbation during infection. Further studies are needed to determine whether MG patients are at higher risk for complications than the rest of the population.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mus.27919","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T10:45:24Z","timestamp":1686912324000},"page":"171-175","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["<scp>COVID<\/scp>\u201019 infection in myasthenia gravis: Clinical course and outcomes"],"prefix":"10.1002","volume":"68","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2227-884X","authenticated-orcid":false,"given":"Eleanor V.","family":"Thomas","sequence":"first","affiliation":[{"name":"Department of Neurology Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2792-0953","authenticated-orcid":false,"given":"Gabriela","family":"Bou","sequence":"additional","affiliation":[{"name":"Department of Neurology Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7439-5787","authenticated-orcid":false,"given":"Shawn","family":"Barton","sequence":"additional","affiliation":[{"name":"Department of Neurology Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5644-9638","authenticated-orcid":false,"given":"Spencer","family":"Hutto","sequence":"additional","affiliation":[{"name":"Department of Neurology Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4602-1766","authenticated-orcid":false,"given":"Rocio","family":"Garcia\u2010Santibanez","sequence":"additional","affiliation":[{"name":"Department of Neurology Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7101a4"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000009566"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev\u2010med\u2010042220\u2010011857"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.14690"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2020.116888"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.26918"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2020.01053"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.27497"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.14951"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000011669"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474\u20104422(20)30413\u20100"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1212\/wnl.55.1.16"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clineuro.2022.107140"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2022.802559"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm6924e2"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.15348"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00415\u2010022\u201011140\u20109"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2020.116803"}],"container-title":["Muscle &amp;
