ABSTRACT
INTRODUCTION:
Neuroinfection is associated with the deposition of amyloid-beta (Aß) peptides, and subsequent decrease in cerebrospinal fluid (CSF) amyloid levels. However, whether autoimmune encephalitis involves extracellular deposition of Aß peptides in the brain is unreported.METHODS:
We examined CSF amyloid and tau values in adults with anti-N-methyl-D-aspartate receptor encephalitis (NMDAR-E). Forty-two patients with NMDAR-E, 35 patients with viral and bacterial neuroinfections, and 16 controls were included. We measured CSF Aß1-42 (cAß1-42), Aß1-40 (cAß1-40), t-Tau (ct-Tau), and p-Tau181 (cp-Tau181) levels and assessed their efficacies regarding differential diagnosis and predicting prognosis.RESULTS:
NMDAR-E patients had lower cAß1-42 levels; however, they were higher than those of patients with bacterial meningitis. ct-Tau levels in NMDAR-E patients were lower than those in patients with neuroinfections. No changes were observed in controls. cAß1-42 and ct-Tau were combined as an excellent marker to distinguish NMDAR-E from neuroinfections. cAß1-42 levels in NMDAR-E patients were positively correlated with Montreal Cognitive Assessment scores. We observed an inverse relationship between cAß1-42 levels and modified Rankin Scale scores. Patients with poor outcomes exhibited low cAß1-42 levels and high levels of several blood parameters. cAß1-42 was the highest quality biomarker for assessing NMDAR-E prognosis. Correlations were found between cAß1-42 and some inflammatory indicators.CONCLUSION:
cAß1-42 was decreased in NMDAR-E patients. cAß1-42 levels indicated NMDAR-E severity and acted as a biomarker for its prognosis. Combining cAß1-42 and ct-Tau levels could serve as a novel differential diagnostic marker for NMDAR-E.Palavras-chave
