Abstract Background: Spexin is a novel peptide implicated in food intake and obesity. The primary aim of this study was to analyze whether serum spexin levels, along with total leptin and active ghrelin levels were different in prepubertal children born small for gestational age(SGA) and appropriate for gestational(AGA). Secondary aims were to analyze whether serum spexin, leptin and active ghrelin levels correlated with metabolic syndrome(MS)antecedents according to the Dietary and lifestyle-induced health effects in children and infants (IDEFICS)study. Subjects and Methods: We conducted a cross-sectional study on prepubertal37SGA- (median:5.6yr)and50prepubertalAGA-born children(median:5.9yr). Anthropometric data, homeostasis model assessment of insulin resistance(HOMAIR),plasma lipids, serum spexin, total leptin and active ghrelin levels were analyzed. Associations of serum spexin levels with MS antecedents according to the IDEFICS study were investigated. Results: Children bornSGA had higher body mass index and waist circumference than AGA-born peers(p <0.05). Serum total leptin levels were higher in SGA-born children than in AGA-born peers (p<0.05). Plasma active ghrelin and spexin levels were not different between the subgroups(p>0.05). Children bornSGA had higher MS risk scores than AGA-born peers(p <0.05). Small for gestational age- born children had higher plasma glucose,insulin and HOMA-IR than AGA-born peers(p<0.05). In children born SGA, the number of subjects with excess adiposity (NSGA=18(43.9%)andNAGA=7(14%),p=0.016)and insulin resistance(NSGA=14(34%) andNAGA=6(12%),p=0.035)was higher than in AGA-born peers. There was no significant difference in frequency of dyslipidemia between the subgroups(p=0.19). The frequency of children with more than one MS antecedent was higher in SGA-born children than in AGA-born peers(Chi-Square p <0.01). Metabolic syndrome risk score according to IDEFICS was higher in SGA born children than in AGA-born peers(2.2±1.8vs1.1±1.8;p=0.008). Serum spexin levels were lower in children with MS antecedents than those without MS antecedents in both AGA -and SGA-born children[Serum spexin levels in AGA-born children with and without MS antecedents: 48,5pg/mL(25-75%IQR:19.8-93.8pg/mL)and143pg/mL(25-75%IQR:104-211pg/mL),p<0.001;respectively, serum spexin levels inSGAborn children with and without MS antecedents: 31,0pg/mL(25-75%IQR:16.5-47.0 pg/mL) and79.5pg/mL(25-75% IQR:49.5-274.8pg/mL),p=0,0016;respectively]. In the whole study group, the most important factor associated with excess adiposity was history of being born SGA(OddsRatio=91.3[95%CI:2.2-374;p=0.017] Conclusions: Serum spexin levels were not different inSGA- and AGA-born children. Serum spexin levels were reduced in children with MS antecedents independent of size at birth.

ObjectiveTo compare postdischarge growth, adiposity and metabolic outcomes of appropriate for gestational age (AGA) versus small for gestational age (SGA) premature infants fed an exclusive human milk (HM)-based diet in the neonatal intensive care unit.DesignPremature infants (birth weight ≤1250 g) fed an exclusive HM-based diet were examined at 12–15 months corrected gestational age (CGA) (visit 1) for anthropometrics, serum glucose and non-fasting insulin, and at 18–22 months CGA (visit 2) for body composition by dual-energy X-ray absorptiometry.ResultsOf 51 children, 33 were AGA and 18 were SGA at birth. The SGA group had weight gain (g/day) equal to AGA group during the follow-up period. SGA had a significantly greater body mass index (BMI) z-score gain from visit 1 to visit 2 (0.25±1.10 vs −0.21±0.84, p=0.02) reflecting catch-up growth. There were no significant differences in total fat mass (FM) and trunk FM between groups. SGA had significantly lower insulin level (5.0±3.7 vs 17.3±15.1 µU/mL, p=0.02) and homeostatic model of assessment-insulin resistance (1.1±0.9 vs 4.3±4.1, p=0.02). Although regional trunk FM correlated with insulin levels in SGA (r=0.893, p=0.04), they had lower insulin level compared with AGA and no difference in adiposity.ConclusionsSGA premature infants who received an exclusive HM-based diet exhibited greater catch-up growth without increased adiposity or elevated insulin resistance compared with AGA at 2 years of age. An exclusive HM-based diet may improve long-term body composition and metabolic outcomes of premature infants with ≤1250 g birth weight, specifically SGA.

Methylation Profiling

IntroductionPrenatal growth restraint followed by rapid postnatal weight gain increases lifelong diabetes risk. Epigenetic dysregulation in critical windows could exert long-term effects on metabolism and confer such risk.Research design and methodsWe conducted a genome-wide DNA methylation profiling in peripheral blood from infants born appropriate-for-gestational-age (AGA, n=30) or small-for-gestational-age (SGA, n=21, with postnatal catch-up) at age 12 months, to identify new genes that may predispose to metabolic dysfunction. Candidate genes were validated by bisulfite pyrosequencing in the entire cohort. All infants were followed since birth; cord blood methylation profiling was previously reported. Endocrine-metabolic variables and body composition (dual-energy X-ray absorptiometry) were assessed at birth and at 12 and 24 months.ResultsGPR120 (cg14582356, cg01272400, cg23654127, cg03629447), NKX6.1 (cg22598426, cg07688460, cg17444738, cg12076463, cg10457539), CPT1A (cg14073497, cg00941258, cg12778395) and IGFBP 4 (cg15471812) genes were hypermethylated (GPR120, NKX6.1 were also hypermethylated in cord blood), whereas CHGA (cg13332653, cg15480367, cg05700406), FABP5 (cg00696973, cg10563714, cg16128701), CTRP1 (cg19231170, cg19472078, cg0164309, cg07162665, cg17758081, cg18996910, cg06709009), GAS6 (N/A), ONECUT1 (cg14217069, cg02061705, cg26158897, cg06657050, cg15446043) and SLC2A8 (cg20758474, cg19021975, cg11312566, cg12281690, cg04016166, cg03804985) genes were hypomethylated in SGA infants. These genes were related to β-cell development and function, inflammation, and glucose and lipid metabolism and associated with body mass index, body composition, and markers of insulin resistance at 12 and 24 months.ConclusionIn conclusion, at 12 months, abnormal methylation of GPR120 and NKX6.1 persists and new epigenetic marks further involved in adipogenesis and energy homeostasis arise in SGA infants. These abnormalities may contribute to metabolic dysfunction and diabetes risk later in life.

Abstract Context: Low birth weight is associated with an increased risk of metabolic and cardiovascular diseases in adulthood. The development of insulin resistance (IR) seems to play a pivotal role; no data on the oxidant-antioxidant status are available in this risk group. Objective: This study is an assessment of oxidant-antioxidant status in prepubertal children born small for gestational age (SGA) in comparison to healthy controls and the relationship to IR. Design: This cross-sectional study compares indexes of IR and oxidant-antioxidant status in three different groups (SGA+, SGA−, controls), with analysis by post hoc and Pearson correlation. Setting: The study was conducted in the Academic Department of Pediatrics. Participants: A total of 19 SGA+ and 16 SGA− children were compared with 13 controls. Intervention: No intervention was used. Main Outcome Measures: Indexes of IR (glucose to insulin ratio, homeostasis model assessment of IR) were evaluated, and markers of oxidative stress (lag phase, malonildialdehyde, vitamin E) were measured. Results: Homeostasis model assessment of IR was significantly higher in SGA+ than SGA− children (1.32 ± 0.9 vs. 0.69 ± 0.47; P = 0.03) and controls (0.71 ± 0.37; P = 0.04). Glucose to insulin ratio was significantly lower in SGA+ than SGA− children (12.41 ± 5.01 vs. 26.54 ± 17.18; P = 0.02) and controls (26.96 ± 20.70; P = 0.04). Lag phase was significantly shorter in SGA+ than SGA− children (24.3 ± 4.38 vs. 35.59 ± 11.29 min; P = 0.003) and controls (45.28 ± 7.69 min; P = 0.0001) and in SGA− than controls (P = 0.01). Malonildialdehyde was significantly higher in SGA+ than SGA− children (0.79 ± 0.3 vs. 0.6 ± 0.1 nmol/mg; P = 0.03) and controls (0.36 ± 0.04 nmol/mg; P = 0.0001) and in SGA− children than controls (P = 0.02). Vitamin E was significantly reduced in SGA+ children than controls (27.54 ± 7.9 vs. 43.23 ± 11.32 μmol/liter; P = 0.002). Conclusion: Oxidative stress is present in both SGA+ and SGA− children, with a continuous alteration in relation to IR. Therefore, catch-up growth might exert the greatest influence in the development of future diseases.
