Abstract
OBJECTIVE: A large body of evidence suggests that stroke and depression are accompanied by activation of inflammatory pathways. Thus, the primary purpose of this study was to assess the high-sensitivity C-reactive protein (Hs-CRP) to the presence of post stroke depression (PSD). METHODS: Two hundred and twenty-six ischemic stroke patients admitted to the hospital within the first 24 hours after stroke onset were consecutively recruited and followed up for 6 months. Clinical information was collected. Serum Hs-CRP levels were measured at baseline. Based on the symptoms, diagnoses of depression were made in accordance with DSM-IV criteria for depression at 6-month after stroke. RESULTS: At 6-month, ninety-five patients (42.0%) showed depression at 6 months after admission and in 69 patients (30.5%) this depression was classified as major. In the 69 patients with major depression, our results showed significantly higher Hs-CRP levels (1.54[IQR, 0.79-2.27]mg/dL vs. 0.43[IQR, 0.31-1.27]mg/dL, P<0.0001) at admission than patients without major depression. After adjusting for NIHSS on admission and all other recorded confounders, Hs-CRP still was an independent predicator of PSD with an adjusted OR of 1.339 (95% CI, 1.231-1.456; P<0.001). Further, in our study, we found that an increased risk of PSD was associated with serum Hs-CRP levels ≥0.85mg/dL (adjusted OR 7.830, 95% CI: 4.193-14.620) after adjusting for above recorded confounders. CONCLUSION: Elevated Hs-CRP serum levels at admission was found to be associated with depression 6-month after stroke, suggesting that these alterations might participate in the pathophysiology of depression symptoms in stroke patients.
