title: [Lipoprotein-associated phospholipase A2 in subjects at low and moderate risk estimated by the SCORE scale].
abstract: The aim of the work was to elucidate the relationship between PLA2 content and results of the tests of abnormal lipid transfer in lipoproteins (LP) in subjects at low and moderate risk estimated by the SCORE scale. Another aim was to estimate the diagnostic value of plasma PLA2 content that was determined in 378 subjects (285 women and 93 men) aged 30-64 yr at low and moderate risk (SCORE scale). The patients were divided into groups depending on the age, the number of atheroscleroic plaques (ACP) in carotid arteries (0ACP 1 ACP, more than 1 ACP), enhanced and normal PLA2 levels. PLA2 was measured using PLAC Test Elisa Kits (DiaDexus, USA), with the upper normal limit assumed to be 200 ng/ml. In women, PLA2 levels positively correlated with apoA-1 (main HDLP apoprotein) content (r = 0.51, p < 0.03); in men, PLA2 negatively correlated with TG (r = -0.38, p < 0.01); in subjects with homogeneous ACP PLA2 positively correlated with LP(a) (r = -.38, p < 0.03). Simultaneous rise in PLA2 and LP(a) levels may be a significant risk factor of atherosclerosis and atherothromhosis. Enhanced levels of TG, PLA2, and LP(a) may be the biochemical triad of "soft" plaque formation in the intima.
