Therapeutic Options to Reduce Lp-PLA2 Levels and the Potential Impact on Vascular Risk Reduction

Cerebrovascular Disease and Stroke (C Helgason and M Alberts, Section Editors)

Opinion statement

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an enzyme involved in the metabolism of Low-density lipoprotein (LDL) to pro-inflammatory mediators. Lp-PLA2 is highly expressed in the necrotic core of atherosclerotic plaques and has been associated with atherosclerotic plaque instability. Multiple studies have shown an association between elevated Lp-PLA2 levels and risk of both stroke and myocardial infarction, even after adjustment for standard vascular risk factors, and several professional organizations have recommended Lp-PLA2 as a potentially usefully tool to improve risk stratification for individual patients. Therapies directed at lowering Lp-PLA2 levels may represent a novel approach to reducing vascular risk, though direct clinical benefit from targeting treatment to Lp-PLA2 levels remains unproven. Statins appear to significantly lower Lp-PLA2 levels; fibrates and niacin may also lower Lp-PLA2 levels, though this is less well established. Darapladib, a potent, selective Lp-PLA2 inhibitor, is currently in phase III trials for prevention of recurrent vascular events in patients with coronary artery disease.

Relationship of lipoprotein-associated phospholipase A(2) mass and activity with incident vascular events among primary prevention patients allocated to placebo or to statin therapy: an analysis from the JUPITER trial. Clin Chem. 2012;58(5):877–86. This study presents a post-hoc analysis of Lp-PLA2 in the large, randomized JUPITER trial comparing rosuvastatin to placebo in 17,000 patients with elevated CRP but no history of vascular disease. At baseline, levels of Lp-PLA2 mass and activity had a moderate correlation both with each other and LDL. In study participants assigned placebo, Lp-PLA2 activity (p=0.04) but not mass (p=0.92) was associated with vascular events after adjustment for LDL and standard vascular risk factors. In the rosuvastatin treated group, there was no association between Lp-PLA2 levels and vascular events. Rosuvastatin significantly reduced Lp-PLA2 mass by 33.8 % and Lp-PLA2 activity by 33.2 % compared to an 11.7 % and 1.7 % reduction, respectively, in the placebo group (both comparisons p < 0.0001). Rosuvastatin was associated with a significant reduction in vascular events, but this was not modified by baseline Lp-PLA2 levels.PubMedCrossRefGoogle Scholar

In this study, Lp-PLA2 and sPLA2 levels in 2500 subjects with acute coronary syndromes enrolled in the MIRACL trial and randomized to atorvastatin or placebo were analyzed. Baseline levels of Lp-pLA2 activity and mass were not associated with the primary study outcome (death, myocardial infarction, or unstable angina at 4 months), nor were levels of sPLA2. In the overall cohort, baseline sPLA2 mass was associated with mortality in multivariate analysis (p=0.004); this association was driven the the placebo group, as when analyzed separately no association was seen in the atorvastatin group. Atorvastatin significantly reduced sPLA2 mass compared to placebo (−32.1 vs. -23.1 %), as well as sPLA2 activity (−29.5 vs. -19.2 %) and Lp-PLA2 mass (−35.8 vs. -6.2 %) and activity (−24.3 vs. 5.4 %), (p<0.001 for all comparisons). The authors conclude that by modulating sPLA2 levels, atorvastatin reduced the risk of death by about 50 %.PubMedCrossRefGoogle Scholar
