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.

AbstractBackground:Fibroblast growth factor 21 (FGF-21) is a hepatic protein that plays a critical role in liver, adipose tissue, and bone metabolism. Animal models reported an increase of FGF-21 and associated growth disturbances in undernutrition. Therefore, we studied the impact of weight loss in obese children on growth, FGF-21, and insulin-like factor 1 (IGF-1) concentrations.Methods:We analyzed height, serum concentrations of FGF-21, IGF-1, IGFBP-3, leptin, and insulin at baseline and 1 year later in 30 obese children with substantial weight loss (reduction >0.5 BMI-SDS) and in 30 obese children of similar age, gender, and pubertal stage with stable BMI-SDS. All children participated in a 1-year lifestyle intervention. Height and IGF-1 was transformed to standard deviation score (SDS). Multiple linear regression analyses adjusted for age, gender, and pubertal stage were performed.Results:At baseline, height-SDS was significantly related to IGF-1-SDS (β-coefficient 0.68 95% confidence interval (95% CI)±0.49; p=0.008) and leptin (β-coefficient 0.042 95% CI±0.030; p=0.008), but not to FGF-21 or insulin. FGF-21 was not significantly associated with IGF-1 or IGFBP-3. In longitudinal analysis, changes of FGF-21 were not significantly related to changes of height, IGF-1-SDS or IGFBP-3. However, in the subgroup of 30 children with substantial BMI-SDS reduction, FGF-21, leptin, insulin, and HOMA decreased significantly.Conclusion:As there was no significant association between FGF-21 and growth or IGF-1 both in cross-sectional and longitudinal analyses, these findings do not support the hypothesis that FGF-21 is involved in growth of obese children. Further studies are necessary to understand the multiple alterations in the growth hormone (GH) axis in obese children.

Propose: To investigate the temporal relationship between plasma fibroblast growth factor 21 levels, insulin resistance, metabolic dysfunction and cardiac fibroblast growth factor 21 resistance in long-term high-fat diet–induced obese rats. Methods: In total, 36 male Wistar rats were fed with either a normal diet or high-fat diet for 12 weeks. Blood was collected from the tail tip, and plasma was used to determine metabolic profiles and fibroblast growth factor 21 levels. Rats were sacrificed at weeks 4, 8 and 12, and the hearts were rapidly removed for the determination of cardiac fibroblast growth factor 21 signalling pathways. Results: Body weight and plasma fibroblast growth factor 21 levels were increased after 4 weeks of consumption of a high-fat diet. At weeks 8 and 12, high-fat diet rats had significantly increased body weight and plasma fibroblast growth factor 21 levels, together with increased plasma insulin, HOMA index, area under the curve of glucose, plasma total cholesterol, plasma low-density lipoprotein cholesterol, serum malondialdehyde and cardiac malondialdehyde levels. However, plasma high-density lipoprotein cholesterol levels and cardiac fibroblast growth factor 21 signalling proteins (p-FGFR1 Tyr154, p-ERK1/2 Thr202/Tyr204 and p-Akt Ser473) were decreased, compared with normal diet rats. Conclusion: These findings suggest that plasma fibroblast growth factor 21 levels could be an early predictive biomarker prior to the development of insulin resistance, metabolic disturbance and cardiac fibroblast growth factor 21 resistance.

Abstract Background: Fibroblast growth factor 19 (FGF19), Fibroblast growth factor 21 (FGF21) and Klotho are regulators of energy homeostasis. However, in the paediatric population the relationship between obesity, metabolic disorders and mentioned factors has not been clearly investigated. We analysed serum concentrations of FGF19, FGF21 and Klotho in children and adolescents with normal body weight as well as in overweight and obese subjects – and their associations with components of metabolic syndrome and insulin resistance (IR).Methods: The cross-sectional study conducted in the group of hospitalised children and adolescents. Laboratory investigation included serum ELISA tests for FGF19, FGF21, Klotho as well as lipid profile and oral glucose tolerance test for calculation of the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index. The clinical analysis included blood pressure measurement, body fat percentage estimation and assessing the prevalence of metabolic syndrome (MS) and its components. Results: The study was conducted on 174 children/adolescents aged 6-17 years divided into the following groups: with normal body weight (N=48), with obesity (N=92) and overweight subjects (N=34). Klotho levels were significantly higher in the group of subjects with obesity [median 168.6 pg/ml]) than those with overweight [131.3 pg/ml] and normal body weight [116.6 pg/ml] (p=0.0334). Median serum FGF21 level was elevated in the group of patients with MS in comparison to other subjects [136.2 pg/ml vs 82.6 pg/ml, p=0.0285]. Increased Klotho concentrations were noted in patients affected by IR compared with subjects with normal insulin sensitivity [185.3 pg/ml vs 132.6 pg/ml, p=0.0282]. Multivariable model for HOMA-IR showed FGF19 as an independent predictor for IR after adjusting for the pubertal stage and BMI Z-score.Conclusions: Klotho levels were associated with body weight status in children and adolescents. Moreover, Klotho, FGF19 and FGF21 concentrations correlated with IR status and traits of MS.

Advanced glycation end products (AGEs) may induce cardiac remodeling in kidney disease by promoting fibroblast growth factor 23 (FGF-23) expression. Since AGEs are increased in diabetes mellitus (DM), our first aim was to evaluate the existence of any potential association between AGEs, FGF-23, inflammation, and increased cardiovascular risk in DM patients on dialysis (CKD-G5D). Secondarily, we explored the potential role of the soluble receptor for AGEs (sRAGE) as a marker of heart failure. Levels of glycated albumin (GA), sRAGE, c-terminal FGF-23 (cFGF-23), brain natriuretic peptide (BNP), and inflammatory mediators were compared between DM and non-DM CKD-G5D patients. The levels of sRAGE, cFGF-23, BNP, and proinflammatory markers were over the ranges of normality in both DM and non-DM groups. Only GA and sRAGE levels were increased in DM compared to non-DM patients. Plasma levels of sRAGE and CRP were the only independent predictors of BNP concentration. In conclusion, in DM CKD-G5D patients, sRAGE appeared to be a marker of cardiac remodeling. Indeed, its increase could be a potential protective mechanism against the increased risk of cardiovascular complications related to AGEs and inflammation. The causal relationship between sRAGE and cardiovascular risk in these patients needs to be further confirmed by mechanistic studies.

Obesity in adults and children is characterized by epidemiological prevalence with a tendency to increase. Purpose of the study- to analyze the lipid profile in overweight children, depending on the presence of insulin resistance. 247 overweight and obese children aged 2 to 18 were examined, including 160 boys and 87 girls. Obesity was diagnosed if the BMI exceeded 97 percentile, according to gender and age. Assessment of the lipid profile included measurements of total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein. To evaluate the parameters of the lipid profile, we used the National Cholesterol Education Program (NCEP) according to the latest edition (2006). We analyzed lipid values depending on the presence or absence of insulin resistance. BMI was also evaluated according to Z-BMI. Insulin resistance was detected in 69.9% of children. Hyperlipidemia was detected in 24.9% of children and dyslipidemia in 83% of the children examined. A change was found in all indicators of the lipid profile, depending on the presence of insulin resistance. A significant increase in Z-BMI was revealed depending on the presence of insulin resistance. Conclusions: Most overweight children have insulin resistance and dyslipidemia; the type of dyslipidemia in children with obesity directly depends on the presence of insulin resistance.
