Interleukin 1-beta is Linked to Chronic Low-Grade Inflammation and Cardiovascular Risk Factors in Overweight Adolescents

Endocr Metab Immune Disord Drug Targets. 2020;20(6):887-894. doi: 10.2174/1871530319666191116141159.

Abstract

Aim: We hypothesized that IL-1β concentrations are augmented in overweight adolescents, who do not display metabolic syndrome. Additionally, we aimed to correlate the IL-1β concentrations with several established risk factors for CVD.

Methods: Overweight or control subjects, aging from 14-18 years, were classified according to their adjusted body mass index and evaluated for biochemical and anthropometric parameters. The proinflammatory cytokine IL-1β was assessed in the serum.

Results: Increased body fat percentage, waist circumference, triglycerides, total cholesterol, Very Low-Density Lipoprotein (VLDL) cholesterol, Low-Density Lipoprotein (LDL) cholesterol, Castelli I index, IL-1β, and IL-8 levels, were observed in overweight adolescents. No differences were observed in systolic blood pressure, diastolic blood pressure, glucose or High-Density Lipoprotein (HDL) cholesterol. Positive correlations between IL-1β with anthropometric and or biochemical parameters were found.

Conclusion: In conclusion, increased IL-1β levels correlate to dyslipidemic factors and may further support low-grade inflammation. IL-1β may further predict the early onset of cardiovascular disease in this population, taking into consideration its important regulatory role.

Keywords: Childhood; cytokine; dyslipidemia; inflammation; interleukins; obesity.
