ObjectivesWe aimed to perform a preliminary analysis of early cytokine profiles in blood between patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis and viral encephalitis (VE), and to observe potential preliminary trends.MethodsThis study adopted a retrospective design. Following a standardized screening process, anti-NMDAR encephalitis (n = 15), VE (n = 15), and non-inflammatory central nervous system diseases as controls (n = 15) were retrospectively enrolled.

Correlations between candidate biomarkers and clinical characteristics of two kinds of encephalitis patients were analyzed.ResultsThis study identified significant alterations in the CSF/serum albumin ratio (QAlb), IL-4 and IL-17A levels across among the two patient groups and controls. These markers exhibited certain diagnostic potential for differentiating anti-NMDAR encephalitis from VE.

In the anti-NMDAR encephalitis group, IL-17A and QAlb were positively correlated with the patients’ hospital stay duration and mRS score at admission (P<0.05). In the VE group, IL-4 and QAlb were associated with the patients’ hospital stay duration and disease severity (P<0.05), with IL-4 showing a negative correlation.

Clinical Editorial

Scope and design

A retrospective pilot analysis comparing early blood cytokine profiles among anti-NMDAR encephalitis, viral encephalitis (VE), and non-inflammatory CNS controls.
Study groups: anti-NMDAR encephalitis (n = 15), VE (n = 15), control with non-inflammatory CNS disease (n = 15).
Objective: to identify preliminary markers and potential diagnostic distinctions between anti-NMDAR encephalitis and VE; correlations with clinical characteristics were explored.

Key biomarkers and patterns

Significant alterations were observed in CSF/serum albumin ratio (QAlb), interleukin-4 (IL-4), and interleukin-17A (IL-17A) across the two encephalitis groups and controls.
These markers showed potential utility for differentiating anti-NMDAR encephalitis from VE, based on observed differences among groups.

Correlations with clinical severity

In the anti-NMDAR cohort, IL-17A and QAlb demonstrated positive associations with hospital stay duration and with the modified Rankin Scale (mRS) score at admission (P<0.05).
In VE patients, IL-4 and QAlb were linked to hospital stay duration and disease severity, with IL-4 showing a negative correlation (P<0.05).

Limitations and interpretation

Findings are preliminary and derived from a small retrospective sample; results require validation before clinical translation.

Context and implications

Elevated inflammatory indicators may function as candidate biomarkers to assist early differential diagnosis between anti-NMDAR encephalitis and VE, warranting further prospective investigation.
