Correlation analysis between post-stroke depression and serum bilirubin and high-sensitivity C-reactive protein / 中国基层医药

ABSTRACT

Objective:To analyze the influential factors of post-stroke depression and investigate the effects of changes in serum bilirubin and high-sensitivity C-reactive protein on post-stroke depression.Methods:A total of 199 patients with stroke admitted to Qinghai Provincial People's Hospital from December 2019 to December 2020 were included in this study. These patients were divided into the Xining urban group (2 000-3 000 meters above sea level; n = 165) and the Xining prefecture and county group (over 3 000 meters above sea level; n = 34) according to their long-term residence. They were also divided into the post-stroke depression group ( n = 56, including 45 patients in the Xining urban group and 11 patients in the Xining prefecture and county group) and non-post-stroke depression group ( n = 143, including 120 patients in the Xining urban group and 23 patients in the Xining prefecture and county group). Related scales were used to evaluate neurologic deficits and the degree of depression in the two groups. Serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein were measured in each group. Neurologic deficits and the degree of depression were correlated with serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein. Results:Serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein in the post-stroke depression group were (19.95 ± 7.22) mmol/L, (3.98 ± 1.49) mmol/L, and (1.40 ± 2.29) mg/L, respectively, which were significantly higher than (16.20 ± 7.61) mmol/L, (3.19 ± 1.62) mmol/L, and (0.63 ± 1.33) mg/L in the non-post-stroke depression group ( t = 3.17, 3.18, 2.35, all P < 0.05). There was a significant difference in serum level of high-sensitivity C-reactive protein between stroke patients with mild and moderate depression and stroke patients with severe depression ( t = 2.48, P < 0.05). Conclusion:Serum levels of bilirubin and high-sensitivity C-reactive protein play an important role in the pathogenesis of post-stroke depression and there is a significant correlation between the two.
