The relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2), cholesteryl ester transfer protein (CETP), and risk of atherosclerosis in IDA women has not been fully clarified. The objective of this study was to investigate lipid-related atherogenic risk factors in women with IDA.
Eighty women with IDA and 80 age-matched healthy women as the control group were enrolled in the study. Serum lipid profile, Lp-PLA2, and CETP were determined. Correlations between lipid-related atherogenic risk factors were analyzed by Pearson's correlation analyses.
TG levels were higher and HDL-C levels were lower in the IDA women. Lp-PLA2 activity, Lp-PLA2 concentration, and CETP concentration were higher in the IDA women. There were negative correlations between activity or concentration of Lp-PLA2 and hemoglobin level (r = -0.29 or r = -0.33, p < 0.05), as well as HDL-C level (r = -0.38 or r = -0.35, p < 0.05). Positive correlations were observed between Lp-PLA2 activity and Lp-PLA2 concentration and low-density lipoprotein cholesterol (LDL-C) level (r = 0.41 or r = 0.36 respectively, p < 0.05). CETP concentration was negatively correlated with hemoglobin (r = -0.56, p < 0.01) and HDL-C level (r = -0.35, p < 0.05) and positively correlated with triglyceride level (r = 0.34, p < 0.05).
Increases in the levels of circulating CETP and Lp-PLA2 might partly play a role in the atherogenic disturbances in patients with IDA through increased susceptibility to lipid peroxidation.
缺铁性贫血(IDA)女性中脂蛋白相关磷脂酶A2(Lp-PLA2)、胆固醇酯转运蛋白(CETP)与动脉粥样硬化风险之间的关系尚未完全阐明。本研究的目的是调查IDA女性中与脂质相关的动脉粥样硬化危险因素。
本研究纳入了80例IDA女性和80例年龄匹配的健康女性作为对照组。测定血清脂质谱、Lp-PLA2和CETP。通过Pearson相关分析分析脂质相关动脉粥样硬化危险因素之间的相关性。
IDA女性的甘油三酯(TG)水平较高,高密度脂蛋白胆固醇(HDL-C)水平较低。IDA女性的Lp-PLA2活性、Lp-PLA2浓度和CETP浓度较高。Lp-PLA2的活性或浓度与血红蛋白水平(r = -0.29或r = -0.33,p < 0.05)以及HDL-C水平(r = -0.38或r = -0.35,p < 0.05)之间存在负相关。Lp-PLA2活性与Lp-PLA2浓度和低密度脂蛋白胆固醇(LDL-C)水平之间存在正相关(分别r = 0.41或r = 0.36,p < 0.05)。CETP浓度与血红蛋白(r = -0.56,p < 0.01)和HDL-C水平(r = -0.35,p < 0.05)呈负相关,与甘油三酯水平呈正相关(r = 0.34,p < 0.05)。
循环中CETP和Lp-PLA2水平的升高可能通过增加对脂质过氧化的易感性,在IDA患者的动脉粥样硬化紊乱中部分发挥作用。
