Abstract Background Oxidative stress and impaired production of adipokines in childhood obesity contribute to the development of obesity-related disorders. We assessed whether weight loss after lifestyle intervention alters biomarkers of oxidant/antioxidant status, and whether these alterations are associated with changes in anthropometric parameters and adipokines in obese children. Materials and Methods We determined oxidized low-density lipoprotein (ox-LDL), anti ox-LDL, paraoxonase1 (PON1), leptin, soluble leptin receptor (sOB-R), total adiponectin, high molecular weight adiponectin concentrations and body composition (by dual-energy X-ray absorptiometry) in 60 prepubertal obese children (Body Mass Index, BMI Z-score>2) before and after a 3-month intervention. The control group consisted of 44 non-obese children (BMI Z-score<−1+1>). Results Ox-LDL, ox-LDL/LDL, and anti ox-LDL concentrations as well as leptin to sOb-R ratio were reduced (p<0.001; p=0.018; p<0.001; p<0.001, respectively) in obese children with weight loss (BMI Z-score change≤−0.5) after a 3-month therapy. These parameters were stable in the obese group without weight loss (BMI Z-score change>−0.5). Changes in ox-LDL and PON1 levels in all obese children correlated positively with changes in the leptin to sOB-R ratio (r=0.400, p=0.002; r=0.304, p=0.028, respectively). After adjustment for changes in BMI Z-score in the multivariate regression model, the association between the changes in ox-LDL levels and changes in the leptin/sOb-R ratio remained statistically significant (β=0.184, p=0.014). Conclusions We found out that a 3-month lifestyle intervention associated with weight loss improves the oxidant/antioxidant balance and promotes anti-atherogenic changes in prepubertal obese children in a way dependent on the alterations in the leptin to sOB-R ratio.

Oxidative and inflammatory substances play an important role in the genesis of processes related to cardiometabolic risk. High levels of oxidized low-density lipoprotein (Ox-LDL) and of triggering receptor-expressed myeloid cells (TREM-1) are associated with cardiovascular and inflammatory diseases. In this study, we evaluate the association of the plasma concentrations of Ox-LDL and serum levels of circulating TREM-1 (sTREM-1) with the components of cardiometabolic risk (CMR) and other associated risk parameters. Although the individuals in this study were young, nonobese, and did not have signs, symptoms, and diagnosis of diseases, they already presented components of CMR. Ox-LDL lipid fraction correlated positively with CMR-related markers: body mass index (BMI), waist circumference (WC), body fat percentage, total cholesterol, LDL-c, VLDL-c, triglycerides, atherogenic cholesterol, and atherogenic index. Among these parameters, atherogenic cholesterol had a greater predictive effect for Ox-LDL alterations. Individuals with higher serum concentrations of sTREM-1 presented higher values for BMI, WC, triglycerides, VLDL-c, and atherogenic cholesterol. WC showed an effect on the association between the sTREM-1’s inflammatory response and the components of CMR. The association of oxidative and inflammatory markers with anthropometric parameters and atherogenic cholesterol in nonobese, clinically healthy, and young individuals suggests the importance of early evaluation of these markers in order to prevent future cardiac events.

IntroductionOsteoprotegerin has been shown to play a role in vascular calcification, atherosclerosis and the pathogenesis of cardiovascular diseases. We aimed to evaluate whether excess fat mass affects serum osteoprotegerin concentrations and to evaluate its associations with chosen cardiometabolic risk factors in overweight and obese children.Material and methodsWe enrolled 105 children ranging from 7.0 to 17.8 years of age. Among them 70 individuals were overweight and obese, and 35 were healthy with normal physical parameters. In all patients, anthropometric measurements and laboratory tests were performed. Atherogenic and insulin resistance indices were calculated.ResultsWe did not find any differences in serum osteoprotegerin concentrations between overweight and obese children and their lean peers. In all studied patients, together with elevated quartiles of osteoprotegerin concentration, insulin resistance status decreased, and low-density lipoprotein cholesterol concentration increased. In the group of overweight and obese children osteoprotegerin was associated with low-density lipoprotein cholesterol, total cholesterol, and non high-density lipoprotein cholesterol. In the multiple linear regression analysis osteoprotegerin correlated only with low-density lipoprotein cholesterol (β = 0.140, p = 0.005).ConclusionsInsulin resistance and lipid profile seem to influence circulating osteoprotegerin levels, but most likely needs more time to change its concentration in overweight and obese patients. The association of osteoprotegerin with low-density lipoprotein cholesterol may suggest its link with atherogenesis.

Background Fibroblast growth factor 1 (FGF1) can regulate glucose and lipid metabolism in obese mice. Serum FGF1 has increased in type 2 diabetes mellitus adults and correlated with BMI. This study aimed to indicate conventional weight loss effects on FGF1 in obese children and adolescents. Materials and methods Clinical and metabolic parameters of 88 lean and obese individuals (ages 5–15 years) and 39 obese individuals followed with 6 months of lifestyle intervention were collected. Serum FGF1 levels were detected through enzyme-linked immunosorbent assays. Results FGF1 levels were increased in obese individuals. Serum FGF1 levels were significantly correlated with BMI and waist circumferences (r = 0.377, P = 0.012; r = 0.301, P = 0.047, respectively). Multivariate stepwise linear regression analyses showed that FGF1 levels were significantly correlated with HbA1c and HOMA-IR (β = 0.371, P = 0.008; β = 0.323, P = 0.021, respectively). Weight loss (2.3 ± 0.1 kg) was accompanied by a significant reduction of circulating FGF1 levels (7.2 ± 0.4 pg/mL). Changes in FGF1 were significantly correlated with changes in fasting glucose, HOMA-IR and low-density lipoprotein cholesterol (β = 0.277, P = 0.020; β = 0.474, P < 0.001; β = 0.320, P = 0.008, respectively). Conclusion FGF1 was related to increased risk of insulin resistance in obese children and adolescents. Serum FGF1 reduced after weight loss in obese individuals and was associated with the improvement of insulin resistance. Changes in serum FGF1 were more correlated with insulin resistance than changes in obesity per se.
