Abstract:
Objective:To investigate the predictive value of serum β 2-microglobulin (β 2M) and pro-inflammatory cytokines for post-stroke depression (PSD) in patients with acute ischemic stroke (AIS). Methods:Patients with AIS admitted to the Department of Neurology, the Affiliated Municipal Hospital of Xuzhou Medical University from January 2020 to May 2023 were included retrospectively. At the 6-month outpatient follow-up, the Self-rating Depression Scale (SDS) was used to assess depression. Multivariate logistic regression analysis was used to determine the independent influencing factors of PSD. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of individual and combined independent influencing factors on PSD. Results:A total of 161 patients were enrolled, including 82 males (50.93%), aged 61.78±11.95 years; 47 patients (29.20%) developed PSD. Univariate analysis showed that the proportion of males, serum β 2M, interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, high-sensitivity C-reactive protein level, and baseline National Institutes of Health Stroke Scale (NIHSS) score in the PSD group were significantly different from those in the non-PSD group (all P<0.05). Multivariate logistic regression analysis showed that serum β 2M (odds ratio [ OR] 4.257, 95% confidence interval [ CI]1.441-12.574; P=0.009), IL-1β ( OR 1.415, 95% CI 1.116-1.793; P=0.004), IL-6 ( OR 1.262, 95% CI 1.020-1.561; P=0.032), and TNF-α ( OR 1.246, 95% CI 1.021-1.521; P=0.030) were the independent influencing factors of PSD. ROC curve analysis showed that the area under the curve of serum β 2M for predicting PSD was 0.753 (95% CI 0.668-0.838), with an optimal cutoff value of 2.255 mg/L. The sensitivity and specificity were 59.6% and 80.7%, respectively. When serum β 2M was combined with IL-1β, IL-6 and TNF-α for prediction, the area under the curve increased to 0.893 (95% CI 0.837-0.948). Conclusion:The serum β 2M in combination with pro-inflammatory cytokines has good predictive value for PSD.
