BACKGROUND: The serum level of LOX-1 ligand containing ApoB (LAB) may reflect atherogenicity better than usual lipid parameters; however, the relationship between LAB and carotid intima-media thickness (IMT) was not clear even in Asian populations. METHODS: A total of 992 community-dwelling Japanese men, aged 40 to 79 years, were enrolled in the present study. Serum LAB levels were measured by enzyme-linked immunosorbent assays (ELISAs) with recombinant LOX-1 and monoclonal anti-apolipoprotein B antibody. RESULTS: Serum LAB levels (median [interquartile range], mu g cs/L) were 5341 mu g cs/L (4093-7125). The mean average IMT of the common carotid artery was highest in the fourth LAB quartile (842 mu m) compared with the first quartile (797 mu m) after adjustment for age, high-density lipoprotein cholesterol, triglyceride, body mass index, hypertension, diabetes, high sensitivity C-reactive protein, smoking, and alcohol drinking. However, this statistically significant difference was lost after further adjustment for total cholesterol (TC). After stratification using the combination of median LAB and hypercholesterolemia (serum TC >= 6.21 mmol/L and/or lipid-lowering medication), the adjusted mean average IMT (standard error) in the high LAB/hypercholesterolemia group was 886 mu m (12.7), 856 mu m (16.7) in the low LAB/hypercholesterolemia group, and 833 mu m (8.4) in the low LAB/normal cholesterol group (P = .004). After further adjustment for TC, mean average IMT in the high LAB group was significantly higher than that measured in the low LAB group in hypercholesterolemic participants not taking lipid-lowering medication. CONCLUSION: Serum LAB was associated with an increased carotid IMT in Japanese men, especially those with hypercholesterolemia. (C) 2016 National Lipid Association. All rights reserved.
