Treatment is focused on resolving the autoimmune condition, usually with corticosteroids. Longer-term treatment of the movement disorder with antiepileptics such as carbamazepine and valproic acid may be necessary.4
Our patient received methylprednisolone IV 1 g/d for 3 days and responded quickly to the treatment. He was discharged to a post-acute rehabilitation hospital on Day 16 with a plan for 21 days of antiviral treatment for an acute CMV infection, 1 month of oral steroid taper for the APS, and continued warfarin treatment. This regimen resulted in complete resolution of his movement disorder and negative testing of antiphospholipid antibodies 16 days after he was discharged from the hospital.
THE TAKEAWAY
This case illustrates the possible reactivation of a herpesvirus (CMV) related to COVID-19 vaccination, as well as the development of APS-related movement disorder and coagulopathy related to acute CMV infection with viremia. Vaccination for the COVID-19 virus is seen as the best intervention available for preventing serious illness and death associated with COVID-19 infection. Thus, it is important to be aware of these unusual events when vaccinating large populations. This case also demonstrates the need to understand the interplay of immune status and possible disorders associated with autoimmune conditions. Keeping an open mind when evaluating patients with post-vaccination complaints is beneficial—especially given the volume of distrust and misinformation associated with COVID-19 vaccination.
