title: [Relationship between concentration of lipoprotein-associated secretory phospholipase A2 and markers of subclinical atherosclerotic lesion of the arterial wall in patients with low and moderate risk by SCORE scale].
abstract: AIM To show relations between a concentration of lipoprotein-associated secretory phospholipase A2 (LPPLa2) and markers of subclinical atherosclerotic lesion of the arterial wall in patients with low and moderate risk by the SCORE scale.
  
  
  METHODS
  A total of 378 individuals with low and moderate risk of atherosclerotic lesion of the arterial wall (285 females, 93 males) were divided into groups by (1) age and sex, (2) number of atherosclerotic plaques (ASP) in the carotid arteries: OASP (n=158), ASP (n=61), more than one ASP (n=159); (3) plaque characteristics: homogeneous (n=31), heterogenous (n=189), (4) the presence of ASP in CA and level of LPPLa2 in the blood (with high content--n=137, with normal content--n=83). Duplex CA scanning was made to estimate intima-media thickness (IMT), to detect AP in the CA. Computer sphygmography estimated velocity of the pulse wave (PWV) from the carotid to femoral artery. Normal values of IMT and PWV were estimated individually with reference to gender and age. LPPLa2 was measured immunoturbodimetrically using diagnostic kits (PLAC Test Elisa Kit, dia Dexus, U.S.A.), shreshold value < 200 ng/ml.
  
  
  RESULTS
  LPPLa2 content medians in different age groups in males and females differed insignificantly. LPPLa2 concentration in the groups of patients regarding ASP in CA was elevated in relation to the threshold value (200 ng/ml) in all the groups but did not significantly differ: 216 (179-257) ng/ml in the group OASP, 226 (190-274) ng/ml--in the group of patients 1ASP and 212 (174-254) ng/ml--in the group of patients more than one ASP (p > 0.05). In the groups with homogeneous and heterogenous ASP significant differencies were neither between the medians nor between frequency of deviation from normal (p = 0.28). 25.5% patients from the group with an elevated level of LPPLa2 had ASP with a hypoechogenic component.
  
  
  CONCLUSIONS
  No significant correlation was revealed between concentration of LPPLa2, IMT PWV, number of ASP and carotid stenosis.
