Relationship among Risk Factors of Atherosclerosis, Leukocyte Count, and Soluble Intercellular Adhesion Molecule-1.

Abstract

We investigated the effects of risk factors of atherosclerosis on soluble intercellular adhesion molecule-1 (sICAM-1) concentration and leukocyte count by using multivariate statistical analysis. The subjects were 90 people who were hospitalized for a complete check-up examination. Eight risk factors were selected as candidates for predictor variables: age, body mass index (BMI), uric acid, glycohemoglobin A1c, number of cigarettes smoked daily, total cholesterol, triglyceride, and high density lipoprotein (HDL)-cholesterol. The predictor variables were selected using a stepwise method, [criterion variable - predictor variable (standardized regression coefficient)]; sICAM1 - age (0.1859), number of cigarettes (0.2558), triglyceride (0.2447); leukocytes - number of cigarettes (0.2827), triglyceride (0.2526), HDL-cholesterol (-0.2800); stab leukocytes - number of cigarettes (0.2460); segmented leukocytes - glycohemoglobin A1c (0.1495), number of cigarettes (0.2716), HDL-cholesterol (-0.3254); lymphocytes - BMI (0.2639), number of cigarettes (0.1495), triglyceride (0.3520); monocytes - glycohemoglobin A1c (0.2617). These findings indicated that the risk factors of atherosclerosis may influence sICAM1 concentration and leukocyte count.
