Abstract
Introduction
There is a complex interplay between systemic autoimmunity, immunosuppression, and infections. Any or all of these can result in neurologic manifestations, requiring diligence on the part of neurologists.
Case report
We herein report a case of a patient on immunosuppressive treatment for a vasculitis that resulted in zoster meningoencephalitis. This was further complicated by the development of anti-NMDAr encephalitis, the etiology of which is undetermined and further discussed in this paper. The patient eventually developed COVID-19 during hospitalization, succumbing to the respiratory infection.
Conclusion
This case emphasizes that post-infectious autoimmune disorders are becoming increasingly recognized and that they should still be considered in patients who are on immunosuppression. Practitioners should be aware of the complex relationship between autoimmunity and immunosuppression and consider both throughout the disease course.
