Are specific viral antibody responses associated with the development of MOGAD compared to RRMS?
EBV serology differs between MOGAD and RRMS, suggesting distinct viral etiologies for these demyelinating diseases.
Our findings suggest that development of MOGAD is neither associated with SARS-CoV-2, HHV6, CMV nor JCV alone. Furthermore, results presented indicate that EBV serology is different in MOGAD patients compared to RRMS, confirming a role of EBV in the development of MS and suggesting that the etiology of MOGAD is different from MS.
Frederiksen et al. (Thu,) studied this question.
