Belimumab shows promise in neuropsychiatric lupus: Another challenge to find the offender

Abstract

AbstractIntroductionAgents that can be used for the treatment of neuropsychiatric lupus (NPSLE) are lacking in the therapeutic armamentarium. Belimumab is a monoclonal antibody targeting the B‐cell activating factor (BAFF) and is approved by the US Food and Drug Administration as an additional treatment for systemic lupus erythematosus patients with persistent disease activity and lupus nephritis (LN); however, severe active central nervous system manifestations were excluded.Case ReportWe report on a treatment‐naïve LN patient with refractory NPSLE complicated with progressive posterior reversible encephalopathy syndrome (PRES) who was successfully treated via the combination of mycophenolate and belimumab, resulting in reversal of persistent headache and neuroradiologic manifestations.ConclusionResearch on this topic could be relevant for identifying a possible correlation between BAFF and psychiatric NPSLE manifestations.
