Abstract:
Objective:To systematically evaluate the associations of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) with post-stroke depression (PSD).Methods:PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang databases were searched to collect literature comparing levels of CRP, IL-6, and TNF-α at the peripheral blood between PSD and non-PSD patients, with retrieval time limit from inception to June 2024. Literature was screened according to inclusion and exclusion criteria, and data were extracted. Newcastle-Ottawa Scale (NOS) was used to assess the quality of included literature. Meta analysis was conducted using Stata 18.0 software, and publication bias was assessed.Results:A total of 21 pieces of literature with 3,177 participants were collected, including 1,425 patients with PSD and 1,752 patients with non-PSD. Meta analysis results showed that CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients (standardized mean difference [ SMD]=0.930, 95% CI: 0.580-1.280, P<0.001). Subgroup analysis results showed that, among the 7 pieces of literature with CRP detection<14 days after stroke, CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=0.640, 95% CI: 0.38-0.89, I2=83.9%, P<0.001); among the 4 pieces of literature with CRP detection≧14 days after stroke, CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=1.450, 95% CI: 0.820-2.090, P<0.001), enjoying higher heterogeneity ( I2=90.6%). IL-6 level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=2.659, 95% CI: 1.583-3.735, P<0.001). No significant difference in TNF-α level at the peripheral blood was noted between PSD patients and non-PSD patients ( SMD=0.403, 95% CI: -0.208-1.014, P=0.196). Conclusion:CRP and IL-6 levels at the peripheral blood in PSD patients are obviuosly higher than those in non-PSD patients, suggesting that CRP and IL-6 may be potential biomarkers for early identification and intervention of PSD.
