Abstract
Background: Leptin has been suggested as a possible cause of atherosclerotic disease. The small dense low-density lipoprotein cholesterol (LDL-C) has also been regarded as a new surrogate marker in atherosclerotic disease. The aim of this study was to evaluate the relationship between the leptin concentration and the small dense LDL-C concentration in Korean type 2 diabetic patients.
Methods: One hundred-ninety one type 2 diabetic patients, who did not use any medication that could affect the concentration of lipid such as statin, fibrate, thiazolidinediones and corticosteroid, were enrolled in this study. We analyzed the relationship between leptin, the small dense LDL-C and the other metabolic parameters.
Results: The small dense LDL-C concentrations were higher in the group with the highest tertile of the leptin value, both in males and females than those patients in the group with the lowest tertile of the leptin value. The small dense LDL-C concentrations were also higher in the group with the highest tertile of leptin divided by the BMI value both in males and females than those patients in the group with the lowest tertile of the leptin value. The leptin concentration was positively correlated with the small dense LDL-C, total cholesterol, triglyceride, LDL-C, insulin and HOMAIR values after adjusting for age, gender and BMI.
Conclusion: The association between leptin and small dense LDL-C could be a factor that explains the association between leptin and cardiovascular disease.
