A Flare of Systemic Lupus Erythematosus Disease After COVID-19 Infection: A Case of Lupus Cerebritis

Abstract

The association between coronavirus disease 19 (COVID-19) and autoimmune disease has been mounting, and literature on COVID-19-induced flare-up of systemic lupus erythematosus (SLE) disease is lacking. We describe a case of lupus cerebritis triggered by COVID-19 in a young female with SLE, who presented with fluctuated mentation, psychomotor retardation, slow speech, and intermittent choreiform movement in the upper part of the body. She had a history of COVID-19 infection three weeks back. Her serum immunoglobulin G antibodies were positive against COVID-19. On examination, she had psychomotor agitation, intermittent choreiform movements of upper limbs, and poor speech. Brain magnetic resonance imaging revealed hyperintense signals in the white matter of both hemispheres, suggestive of lupus cerebritis secondary to COVID-19 infection and lack of any other identifiable risk factor. Management included methylprednisolone, prednisone, and olanzapine. The patient was also placed on monthly intravenous cyclophosphamide, and her condition started improving gradually.
