Correlation between Serum Lipid Parameters and Interleukin-10 Concentration in Obese Individuals

초록

Background: The role of interleukin-10 (IL-10) in humans is controversial because IL-10 has been proposed to exhibit both pro- and anti-inflammatory effects. We aimed to determine the relationships between the changes in these parameters in obese individuals participating in a weight-reduction program. Methods: We measured cardiometabolic parameters including lipid profile and serum IL-10 concentration before and after completion of a 12-week weight-reduction program in 63 non-diabetic obese subjects with a body mass index >= 27 kg/m(2) who had comorbid hypertension or dyslipidemia. All the participants were provided with individual intervention sessions designed to implement lifestyle modifications and administered 120 mg orlistat three times daily for 12 weeks. The relationships between changes in serum IL-10 concentration and changes in cardiometabolic risk factors were analyzed. Results: Changes in serum IL-10 concentration were significantly negatively correlated with changes in total cholesterol (r=-0.377), high-density lipoprotein cholesterol (HDL-C; r=-0.377), and low-density lipoprotein cholesterol (LDL-C; r=-0.278) concentrations. However, there were no correlations between changes in serum IL-10 concentration and changes in other cardiometabolic parameters. Conclusion: Serum IL-10 concentration can increase as serum total cholesterol decreases. Additional studies are needed to explore the mechanisms linking changes in serum IL-10 with serum LDL-C and HDL-C concentrations.
