Abstract:
Objective:To explore the clinical utility of peripheral immune-inflammatory markers in predicting late-life depression with cognitive impairment(LLD+ CI + ). Methods:A cross-sectional study was conducted between January 2020 and December 2021, collecting demographic data, peripheral blood inflammatory markers, and cognitive function scores from 40 patients with LLD+ CI + , 38 patients with late-life depression without cognitive impairment(LLD+ CI -), and 26 healthy controls(HCs). Logistic regression analysis and receiver operating characteristic(ROC)curve analysis were employed to assess the value of peripheral blood inflammatory markers in differentiating LLD+ CI + . Results:Patients with LLD+ CI + exhibited significantly different levels of lymphocytes, C-reactive protein(CRP), systemic immune-inflammation index(SII), systemic inflammation response index(SIRI), neutrophil-to-high-density lipoprotein cholesterol ratio(NHR), and neutrophil-to-lymphocyte ratio (NLR)compared with the LLD+ CI - group and the HGs group( F=4.000, 11.642, 13.541, 10.441, 6.623, 4.193; P=0.022, 0.003, 0.001, 0.005, 0.036, 0.018). The multivariate logistic regression analysis of factors influencing LLD+ CI + revealed that elevated levels of CRP( OR=4.933, 95% CI: 1.385-17.563, P=0.014), SII( OR=5.534, 95% CI: 1.336-22.927, P=0.018), and NLR( OR=3.386, 95% CI: 1.470-7.797, P=0.004)constitute risk factors for geriatric depression with cognitive impairment, while an increased lymphocyte count( OR=0.206, 95% CI: 0.058-0.725, P=0.014)serves as a protective factor.Further analysis identified CRP, lymphocytes, SII, and NLR as significant predictors for LLD+ CI + , with areas under the curve (AUC) values of 0.849(95% CI: 0.760-0.934), 0.847(95% CI: 0.761-0.933), 0.860(95% CI: 0.777-0.943), and 0.857(95% CI: 0.777-0.938), respectively, in distinguishing LLD with or without cognitive impairment. Conclusions:Peripheral immune-inflammatory markers represent an economical and effective approach for investigating the pathophysiological changes and predictive factors associated with LLD+ CI + .These findings provide valuable insights into the underlying mechanisms and potential therapeutic avenues.
