OBJECTIVE: To study the risk of acquiring Corona Virus Disease 2019 (COVID-19) and its outcomes in patients on immunosuppressive therapy (IST) for chronic autoimmune neuromuscular disorders (aNMD) and multiple sclerosis (MS) METHODS: We used TriNetX, a global health collaborative clinical research platform collecting real-time electronic medical records data, which has one of the largest known global COVID-19 database We included patients with chronic autoimmune neuromuscular disorders (aNMD) [myasthenia gravis (MG), inflammatory myositis, and chronic inflammatory neuropathies (CIN)] and MS, based on the International Classification of Disease-10 (ICD-10) coding for one year before January 20th, 2020 We examined the use of IST, rate of COVID- 19, hospitalization, intubation, and mortality among the patients with aNMD and MS RESULTS: A total of 33,451 patients with aNMD and 42,899 patients with MS were included Among them, 111 (0 33%) patients with aNMD and 115 patients (0 27%) with MS had COVID-19 About one third of them required hospitalization IST did not appear to have a significant impact on overall infection risk in either group;however, risk of hospitalization for immunosuppressed patients with aNMD was higher (Odds ratio 2 86, p-value 0 011) CONCLUSIONS: IST use does not appear to make patients with aNMD and MS more vulnerable to COVID-19 IST may be continued during the pandemic, as previously suggested by expert opinion guidelines However, it is important to consider individualizing immunotherapy regimens in some cases Additional physician reported registry-based data is needed to further confirm these findings

OBJECTIVE: To study the risk of acquiring Corona Virus Disease 2019 (COVID-19) and its outcomes in patients on immunosuppressive therapy (IST) for chronic autoimmune neuromuscular disorders (aNMD) and multiple sclerosis (MS). METHODS: We used TriNetX, a global health collaborative clinical research platform collecting real-time electronic medical records data, which has one of the largest known global COVID-19 database. We included patients with chronic autoimmune neuromuscular disorders (aNMD) [myasthenia gravis (MG), inflammatory myositis, and chronic inflammatory neuropathies (CIN)] and MS, based on the International Classification of Disease-10 (ICD-10) coding for one year before January 20th, 2020. We examined the use of IST, rate of COVID- 19, hospitalization, intubation, and mortality among the patients with aNMD and MS. RESULTS: A total of 33,451 patients with aNMD and 42,899 patients with MS were included. Among them, 111 (0.33%) patients with aNMD and 115 patients (0.27%) with MS had COVID-19. About one third of them required hospitalization. IST did not appear to have a significant impact on overall infection risk in either group; however, risk of hospitalization for immunosuppressed patients with aNMD was higher (Odds ratio 2.86, p-value 0.011). CONCLUSIONS: IST use does not appear to make patients with aNMD and MS more vulnerable to COVID-19. IST may be continued during the pandemic, as previously suggested by expert opinion guidelines. However, it is important to consider individualizing immunotherapy regimens in some cases. Additional physician reported registry-based data is needed to further confirm these findings.
