The Intersection of Autoimmunity and Neurology: Insights From a Case of Striatal Lupus Encephalitis.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disorder predominantly affecting women, characterized by the production of autoantibodies against various nuclear antigens, leading to widespread immune dysregulation and multisystem involvement. Among its complex manifestations, neuropsychiatric systemic lupus erythematosus (NPSLE) represents a particularly challenging aspect of the disease due to its wide spectrum of neurological and psychiatric symptoms. This case report presents a rare instance of striatal lupus encephalitis, a severe subtype of NPSLE, in a 32-year-old woman, highlighting its distinct clinical and radiological features. The patient initially developed bilateral ocular occlusive vasculitis and later presented with acute right-sided hemiparesis and facial asymmetry. Magnetic resonance imaging (MRI) revealed bilateral symmetrical T2-weighted and fluid-attenuated inversion recovery (FLAIR) hyperintense signals in the basal ganglia, consistent with striatal lupus encephalitis. No white matter hyperintensity or vasculitis changes were seen. Cerebrospinal fluid analysis revealed markedly elevated protein levels, though no infectious organism was identified. The patient was treated with high-dose prednisolone, alongside empirical antibiotic and antiviral therapy to address potential meningoencephalitis. Remarkably, she made a full recovery from her stroke-like symptoms. Despite its rarity, the identification of striatal lupus encephalitis is critical due to the severe and potentially irreversible nature of the neurological damage. This case underscores the importance of a comprehensive diagnostic approach, integrating clinical, serological, and neuroimaging findings to differentiate striatal lupus encephalitis from other neuropsychiatric conditions associated with SLE. Its management typically involves aggressive immunosuppressive therapy, with intravenous methylprednisolone being the first-line treatment. The case also illustrates the potential for recovery with prompt and appropriate treatment, as evidenced by the complete resolution of neurological symptoms and MRI findings at follow-up.
