Article Abstract
Objective: As no gold-standard diagnostic test exists for neuropsychiatric systemic lupus erythematosus (NPSLE), we undertook this study to execute a broad screen of NPSLE cerebrospinal fluid (CSF) using an aptamer-based platform.
Methods: CSF was obtained from NPSLE patients and subjected to proteomic assay using the aptamer-based screen. Potential biomarkers were identified and validated in independent NPSLE cohorts in comparison to other neurologic diseases.
Results: Forty proteins out of the 1,129 screened were found to be elevated in NPSLE CSF. Based on enzyme-linked immunosorbent assay validation, CSF levels of angiostatin, α2-macroglobulin, DAN, fibronectin, hepatocellular carcinoma clone 1, IgM, lipocalin 2, macrophage colony-stimulating factor (M-CSF), and serine protease inhibitor G1 were significantly elevated in a predominantly White NPSLE cohort (n = 24), compared to patients with other neurologic diseases (n = 54), with CSF IgM (area under the curve [AUC] 0.95) and M-CSF (AUC 0.91) being the most discriminatory proteins. In a second Hong Kong-based NPSLE cohort, CSF IgM (AUC 0.78) and lipocalin 2 (AUC 0.85) were the most discriminatory proteins. Several CSF proteins exhibited high diagnostic specificity for NPSLE in both cohorts. Elevated CSF complement C3 was associated with an acute confusional state. Eleven molecules elevated in NPSLE CSF exhibited concordant elevation in the choroid plexus, suggesting shared origins.
Conclusion: Lipocalin 2, M-CSF, IgM, and complement C3 emerge as promising CSF biomarkers of NPSLE with diagnostic potential.

The BALB/c model of pristane-induced lupus (PIL) exhibits cognitive impairment features resembling neuropsychiatric lupus (NPLSE). Osteopontin (OPN) is associated with disease activity in SLE; however, its involvement in NPLSE is not yet entirely determined. Our study aims to elucidate the contribution of full-length OPN (OPN-FL) plasma expression, OPN N-half, and to cognitive impairment in the PIL mice model.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT) is a rare condition that can present with multiple neurological and psychiatric manifestations. SREAT diagnosis poses a challenge due to the nature of its nonspecific symptomatology and its overlap with numerous autoimmune, metabolic, infectious, and neuropsychiatric disorders. It is associated with elevated anti-thyroid antibodies, occurs in correspondence with autoimmune thyroiditis, and shows great response to corticosteroid treatment.

Background: Neuropsychiatric disorders in systemic lupus erythematosus (NPSLE) are often accompanied by alterations in brain structure and function. Subtle changes in brain structure also can be observed in non-NPSLE patients. MRI can be used as a non-invasive tool to determine nervous system involvement in SLE.

To uncover the clinical characteristics and investigate the underlying causes of psychiatric manifestations in patients with systemic lupus erythematosus (SLE), including its subset, neuropsychiatric systemic lupus erythematosus (NPSLE). Through comprehensive database searches in PubMed, Embase, Medline, and Cochrane, from their inception to August 2023, the study focused on adult SLE and NPSLE cases. From the selected studies, data were synthesised via a random-effects meta-analysis, encompassing a total of 2,997 subjects across six studies.
