Objective Lipoprotein-associated phospholipase A2 (Lp-PLA2) is considered a biomarker for systemic inflammation and the risk of myocardial infarction and stroke. However, little is known about the effect of acute vascular events on marker levels. The purpose of this study was to assess the potential association of early recovery with Lp-PLA2 levels in patients with acute ischemic stroke (AIS) after intravenous thrombolysis (IVT). Methods Forty-three consecutive AIS patients who had their first stroke and were hospitalized within 5 hours of the onset of stroke were enrolled. All patients were treated with IVT using alteplase or urokinase. Plasma Lp-PLA2 levels were measured within 24 hours after IVT. Variables that showed a significant association with Lp-PLA2 in univariate analysis were included in the multivariate ordered logistic regression model. Results Early recovery was associated with Lp-PLA2 levels after IVT, and Lp-PLA2 levels tended to decrease with increased probability of early recovery. This study is the first to report a negative correlation between early recovery and Lp-PLA2 levels after IVT. Conclusion Early recovery after IVT was negatively correlated with Lp-PLA2 A2 levels.
Background: Ischemic stroke is a major cause of disability and mortality in patients with type 2 diabetes mellitus (T2DM), and diabetic stroke has a high recurrence rate. Objectives: This prospective cohort study aimed at investigating the risk factors and establishing Cox’s regression model and personal prognosis index for the recurrence of ischemic stroke at a two-year follow-up in T2DM patients. Methods: T2DM patients with ischemic stroke, who were consecutively admitted to the Neurology Department of North China University of Science and Technology Affiliated Hospital between January 1, 2015, and December 31, 2015, were retrospectively reviewed. These cases were followed up since the onset of ischemic stroke for 2 years. Univariate and multivariate Cox’s proportional hazard regression model was used to analyze risk factors associated with the recurrence rate. Thus, a recurrence model and personal prognosis index were set up. Results: During the follow-up period, 44 cases relapsed. Furthermore, the 1-year recurrence rate was 16.48%, while the 2-year recurrence rate was 24.18%. The univariate and multivariate Cox proportional hazard regression model revealed that the independent risk factors associated with recurrence were TOAST criteria (X1) (RR = 1.663; 95% CI = 1.015 - 2.760, P = 0.032), hypertension grade (X2) (RR = 1.897; 95% CI = 1.097 - 3.280, P = 0.022), duration of diabetes mellitus (X3) (RR = 1.151; 95% CI = 1.009 - 1.991, P = 0.039), total cholesterol (X4) (RR = 1.13; 95% CI = 1.006 - 1.876, P = 0.035), and Essen stroke risk score (ESRS) (X5) (RR = 2.055; 95% CI = 1.357 - 3.134, P = 0.001). The personal prognosis index of the recurrence model was as follows: PI = 0.504 X1 + 0.640 X2 + 0.345 X3 + 0.759 X4 + 0.823 X5. Conclusions: TOAST criteria, hypertension grade, duration of diabetes mellitus, total cholesterol, and ESRS were the independent risk factors associated with the recurrence of ischemic stroke with diabetes mellitus. The recurrence model and personal prognosis index equation were successfully established.
