Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disorder characterized by a wide range of immunological abnormalities. One of its notable features is the potential to affect the central nervous system (CNS), leading to diverse neurological manifestations including headaches, acute state of confusion, seizure disorder, cerebrovascular disease, and meningoencephalitis. CNS involvement is highly prevalent in SLE patients, ranging from 12% to 75%, and is associated with a poor prognosis. Treatment options such as steroids, azathioprine, rituximab, and intravenous immunoglobulins (IVIGs) have been considered in managing these cases. However, early diagnosis of SLE-related CNS involvement remains challenging due to the rapid progression of symptoms and the need to exclude various alternative di-agnoses. In this article, we present a fatal case of an SLE patient with meningoencephalitis, initially resembling an ischemic stroke. Despite administering antibiotics, antiviral agents, IVIGs, steroids, rituximab, and plasma exchange, no clinical improvement was observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
