The study identified Lp-PLA(2) as a potential prognostic and diagnostic biomarker for CKD-CAS, which can be used as an assessment indicator for patient risk factors.
Background: The leading cause of death in patients with chronic kidney disease (CKD) is atherosclerosis (AS). Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is a biomarker of atherosclerotic plaque stability. The aim of our study was to analyze the association of Lp-PLA(2) with CKD complicated with carotid atherosclerotic stenosis (CAS). Methods: Serum specimens were collected from 77 CKD patients and 39 healthy controls. Laboratory examination results including glucose, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and Lp-PLA(2) were measured. Receiver operating characteristic (ROC) was drawn and the area under the curve (AUC) was calculated. Results: Multivariate logistic regression analysis showed that age, gender, glucose, and Lp-PLA(2) were considered as risks for CKD-CAS with odds ratios (OR) of 1.111 (95% CI: 1.055, 1.170), 5.123 (95% CI: 1.482, 17.714), 1.679 (95% CI: 1.123, 2.512), and 1.023 (95% CI: 1.008, 1.037), respectively. The AUC for Lp-PLA(2) and glucose was 0.618 (p = 0.014) and 0.592 (p = 0.057), respectively. The best diagnostic value was archived by Lp-PLA(2) with the cutoff value of 201.06 ng/mL. Conclusions: Lp-PLA(2) is a potential prognostic and diagnostic biomarker for CKD-CAS.
