Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an independent risk factor of cardiovascular disease and a target of treatment. Lp-PLA2 levels in children have not been previously reported. The effect of statin therapy on Lp-PLA2 mass and activity in children with familial hypercholesterolemia (FH) is also not known.


Lp-PLA2 mass and activity levels were measured at baseline and after 2 years in 178 children with FH randomized to pravastatin or placebo and in 78 unaffected and untreated siblings. At the end of the randomized period, all FH children were then placed on pravastatin for an additional 2 years, and Lp-PLA2 mass and activity levels were correlated with changes in carotid intima-media thickness during 4 years of follow-up.


Baseline levels of Lp-PLA2 mass and activity were significantly greater in children with FH compared with unaffected siblings (mass: 240.3 ± 41.6 vs 222.1 ± 36.5 ng/mL, P = .002; activity: 205.7 ± 41.6 vs 124.3±23.0 nmol/min/mL, P < .0001). In the randomized FH cohort, after 2 years treatment, Lp-PLA2 mass (217.8 ± 35.0 vs 231.5 ± 34.8 ng/mL, P = .001) and activity (178.8 ± 37.3 vs 206.2 ± 33.5 nmol/min/mL, P < .0001) were significantly reduced by pravastatin compared with placebo. Change in Lp-PLA2 activity was related to change in low-density lipoprotein cholesterol (pravastatin: r = 0.53, P < .0001, placebo: r = 0.23, P < .001) but change in Lp-PLA2 mass was not related to change in low-density lipoprotein cholesterol. Baseline levels of Lp-PLA2 mass and activity were not significantly associated with carotid intima-media thickness at baseline or at 4 years.


Lp-PLA2 mass and activity are significantly elevated in children with heterozygous FH compared with unaffected siblings and are significantly reduced by pravastatin therapy.

  The National Cholesterol Education Program Adult Treatment Panel guidelines have established low-density lipoprotein cholesterol (LDL-C) treatment goals, and secondary non-high-density lipoprotein (HDL)-C treatment goals for persons with hypertriglyceridemia. The use of lipid-lowering therapies, particularly statins, to achieve these goals has reduced cardiovascular disease (CVD) morbidity and mortality; however, significant residual risk for events remains. This, combined with the rising prevalence of obesity, which has shifted the risk profile of the population toward patients in whom LDL-C is less predictive of CVD events (metabolic syndrome, low HDL-C, elevated triglycerides), has increased interest in the clinical use of inflammatory and lipid biomarker assessments. Furthermore, the cost effectiveness of pharmacological intervention for both the initiation of therapy and the intensification of therapy has been enhanced by the availability of a variety of generic statins. This report describes the consensus view of an expert panel convened by the National Lipid Association to evaluate the use of selected biomarkers [C-reactive protein, lipoprotein-associated phospholipase A2, apolipoprotein B, LDL particle concentration, lipoprotein(a), and LDL and HDL subfractions] to improve risk assessment, or to adjust therapy. These panel recommendations are intended to provide practical advice to clinicians who wrestle with the challenges of identifying the patients who are most likely to benefit from therapy, or intensification of therapy, to provide the optimum protection from CV risk.
