Abstract

SOUKI, Aida et al. Resistin is associated with C reactive protein and cardiovascular risk markers in obese children. Acta bioquím. clín. latinoam. [online]. 2017, vol.51, n.1, pp. 17-27. ISSN 1851-6114.

The aim of this study was to evaluate seric levels of resitin and their association with high-sensitivity C Reactive Protein (hs-CRP), nitric oxide (NO) and plasmatic lipids (PL) in a pediatric age population. A total of 366 children and adolescents (between 10-16 years old) participated, and were grouped into eutrophic (n=162) and obese (n=204). Weight, height, waist circumference, resistin, fasting blood glucose and insulin levels, PL, hs-CRP, NO, malondialdehyde and blood pressure were measured. BMI, waist to height ratio (W/HR) and HOMA-IR were calculated. T-student, ANOVA, Mann-Whitney U-value or Kruskal-Wallis were used to compare between groups and Spearman correlation was used to determine association among variables. Male obese subjects showed higher resistin levels (p<0.05). Female subjects showed higher resistin values in the eutrophic group (p=0.012) and in the normal W/HR (p=0.011). At higher levels of resistin, the eutrophic group showed higher levels of triacylglycerides, but the obese group showed lower triacylglycerides, HDLc and NO levels and higher hs-CRP levels and BMI. These results suggest that resistin could be a risk factor for cardiovascular disease because of its positive association with hs-CRP and inverse association with NO and HDLc, parameters involved in inflammation and endothelial dysfunction.
