An observational study found a high rate of low detection of antibodies in multiple sclerosis patients after COVID-19 infection, suggesting that certain disease-modifying therapies may impact antibody response or persistence.
Background: The COVID-19 pandemic has raised novel concerns for people living with MS regarding their safety. Methods: Observational study of patients at a single comprehensive community MS center. Results: 48 patients with MS were suspected of developing COVID-19 March to May 2020; 2 died. Of the remainder, 17 were tested for COVID-19 antibodies as part of routine care. Average age of this subgroup was 49.8y +/- 11.3 (age range 32-67), 76% female. 65% were treated with an anti-CD20 drug, 12% untreated, and 6% each received glatiramer acetate, interferon, natalizumab, or teriflunomide. 59% of patients were antibody negative. Conclusions: The low incidence of SARS CoV2 antibodies following infection suggests that certain DMTs may alter SARS CoV2-Ab response or persistence.
