Background: Acute ischemic stroke (AIS) leads to neuronal and endothelial damage that activate the release of proinflammatory mediators such as lipoprotein-associated phospholipase A2 (Lp-PLA2), which lead to the development of brain edema injury. Most of statins produce differential effects on Lp-PLA2 activity and mass with a comparable reduction in low-density lipoprotein (LDL) serum levels. Aims: The aim of this study is to evaluate the differential effect of different statins on the mass of level of Lp-PLA2 in patients with AIS. Methods: A total of 69 patients with AIS aged 40–70 years compared with matched 39 healthy controls were involved in this case-control study. The AIS patients were divided according to the statins therapy into 39 patients on statins therapy (statins on), and 30 patients were not on the statins therapy (statins off). Anthropometric variables including weight, height, body mass index (BMI), and blood pressure profile were estimated. Besides, biochemical variables including lipid profile[total cholesterol (TC), triglyceride (TG), LDL, very low-density lipoprotein (VLDL), high-density lipoprotein (HDL)], Lp-PLA2 mass levels, high-sensitive C-reactive protein (Hs-CRP) were estimated. Results: Patients with AIS had high Lp-PLA2 mass levels (P < 0.01) that positively correlated with high Hs-CRP, blood pressure, BMI, TC, TG, VLDL, LDL, and negatively correlated with HDL as compared with healthy controls. As well, statins on patients had lower Lp-PLA2 mass levels (9.82 ± 3.19 IU/mL) compared with statins off patients (16.55 ± 4.72 IU/mL), (P = 0.0001). Regarding the gender differences in the Lp-PLA2 mass level, it was higher in men patients with AIS compared with comparable females (P = 0.03). Conclusions: Lp-PLA2 mass level was higher in patients with AIS and linked with underlying poor cardio-metabolic disorders. Therefore, the Lp-PLA2 mass level is observed to be a surrogate biomarker of AIS mainly in patients with poor cardio-metabolic disorders. Statin therapy improves the Lp-PLA2 mass level and the poor cardio-metabolic profile in patients with AIS.
