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

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.
