ABSTRACT
OBJECTIVE: To study the correlation of serum uric acid (UA), cystatin C (Cys-C) and high-sensitivity C-reactive protein (hs-CRP) with cognitive impairment in lacunar cerebral infarction. METHODS: Total 198 patients with lacunar cerebral infarction were selected and divided into 4 groups according to their cognitive function, with 65 cases in the normal group, 72 cases in the mild cognitive impairment group, 38 cases in the moderate cognitive impairment group and 23 cases in the severe cognitive impairment group. The hs-CRP, serum UA, Cys-C and Montreal Cognitive Assessment (MoCA) were measured upon admission. RESULTS: There were statistical differences in hs-CRP, UA and Cys-C among the four groups (all P<0.001). MoCA was negatively correlated with hs-CRP, UA and Cys-C (all P<0.001). Multivariate logistic regression analysis showed that elevated levels of hs-CRP, UA and Cys-C were the influencing factors of cognitive impairment in patients with lacunar cerebral infarction (all P<0.05). CONCLUSION: The levels of hs-CRP, UA and Cys-C in patients with lacunar cerebral infarction increase with the aggravation of cognitive impairment, and high hs-CRP, UA and Cys-C are independent risk factors of cognitive impairment in patients with lacunar cerebral infarction.
