Determination of inflammation by TNF-alpha and IL-10 levels in obese children and adolescents.

Abstract

childhood obesity is one of the major health problem worldwide. Obesity is associated with low-level chronic inflammation resulting from inflammatory cytokine release in white adipose tissue. We aim to specify inflammatory markers tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) in children and adolescents to determine their relationship with obesity. forty obese patients and 46 controls were included in the study from the pediatric clinic. Blood samples from the study group were centrifuged, and the sera were stored at -80 °C after separation. Serum levels of TNF-alpha and IL-10 were determined using Human ELISA kits for TNF-alpha and IL-10. serum samples from 86 children, including 45 girls (52.3 %) in the study group, were analyzed for TNF-alpha and IL-10 levels. TNF-alpha levels in the obese and control groups were 1.04 ± 0.79 and 0.60 ± 0.72 pg/ml, respectively (p = 0.010). Also, IL-10 levels in the obese and control groups were 0.76 ± 0.62 and 1.54 ± 0.71 pg/ml, respectively (p < 0.001). Gender was not identified as a factor for serum TNF-alpha and IL-10 levels (p = 0.281 and p = 0.477, respectively). Moreover, white blood cell (WBC) and serum C-reactive protein (CRP) levels were higher in the obese patient group than in the control group (p = 0.002 and p = 0.010, respectively). TNF-alpha levels were higher than control in obese patients and it was important in terms of showing that obesity triggers inflammation in the body. IL-10 levels, which inhibit inflammation, were lower in obese patients than controls.
