Background:
Recently, serum lipopolysaccharide-binding protein (LBP) has been closely associated with coronary artery disease. Here, we aimed to investigate the possible relationship between serum LBP and markers of atherosclerosis.
Methods:
Serum LBP and carotid intima media thickness (C-IMT) were measured in 332 subjects (101 men and 231 women) who were recruited from an ongoing multicenter project.
Results:
Serum LBP was significantly associated with obesity [BMI, fat mass and waist circumference (r > 0.38, p < 0.0001)], HOMA (r = 0.36, p < 0.0001) and high sensitivity CRP (hsCRP) (r = 0.50, p < 0.0001). Circulating LBP was also positively associated with C-IMT (r = 0.27, p < 0.0001). Circulating LBP (β = 0.16; p = 0.001) contributed independently to C-IMT variance, after controlling for the effects of age, gender, BMI and hsCRP. Of note, circulating LBP was found to be increased in the population with carotid plaque (n = 50; 32.7 ± 12.5 vs 28.7 ± 10.7; p = 0.021).
Conclusion:
The consistent association between serum LBP and the carotid intima media thickness, a widely used atherosclerosis marker, reveals serum LBP as a putative factor related to atherosclerosis.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
