Abstract
BACKGROUND Antibody levels decline a few months post-acute COVID-19, but humoral memory persists in adults. Age and disease severity may affect antibody responses. This study aims to evaluate the presence and durability of antibody responses in children with COVID-19. METHODS A prospective, single-center study, involving unvaccinated children 0-16 years of age who were hospitalized with COVID-19 between October 2020 and December 2021, was conducted. Serological testing for anti-Spike severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG and neutralizing antibodies was performed at diagnosis and at 1-, 3-, 6- and 12-months post-infection. RESULTS A total of 65 immunocompetent children were enrolled [mean age (±SD): 6.7 (±6.4) years; males: 56.9%]. At 3 months, 40/44 (91%) children were seropositive; seropositivity persisted in 22/26 (85%) children at 6 months and in 10/12 (83%) children at 12 months. There was no evidence that age was modifying the prediction of variance of SARS-CoV-2 IgG levels. In contrast, SARS-CoV-2 IgG levels varied with time and disease severity. The association with time was non-linear, so that with increasing time there was a significant reduction in SARS-CoV-2 IgG levels [coef, 0.044 (95% confidence interval {CI}: 0.061-0.028), P < 0.001]. For each increment of time, the higher disease severity group was associated with 0.9 lower SARS-CoV-2 IgG levels. Everyone varied from the average effect of time with an SD of 0.01, suggesting that individuals may have different trajectories across time. CONCLUSION Disease severity, but not age, influences antibody titers among children hospitalized with COVID-19. SARS-CoV-2 infection induces durable seroconversion in these children with detectable IgG levels at 1 year after infection.

Abstract
Pediatric chronic kidney disease (CKD) patients, as well as kidney transplant patients, are at an increased risk of developing cardiovascular disease. BNP measurement, as a biomarker of cardiovascular risk, has been recommended to this high-risk population. Plasma BNP levels were measured in 56 CKD children in either pre-dialysis stage, hemodialysis (HD) or renal transplant recipients (RTRs) and in 76 sex- and age-matched healthy controls. BNP levels were investigated in HD children, before and after the completion of their HD session. BNP levels in total CKD population, in pre-dialysis stage patients and on HD were significantly higher, compared to the respective controls. HD children had higher BNP levels compared to CKD patients in the pre-dialysis stage. Moreover, post-HD BNP concentration was slightly higher than pre-HD, with the difference being marginally statistically significant. BNP was positively correlated with eGFR, creatinine, cystatin-C and parathormone and negatively with albumin and 25-hydroxyvitamin D. A positive correlation between BNP concentration and the ratio of E/A in pulse-wave Doppler echocardiography was also observed. In conclusion, CKD pediatric patients, mainly those undergoing HD, have high plasma BNP levels which do not decrease after the HD session. This is indicative of a greater risk for future cardiovascular disease.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition affecting 6–18% of adolescents and is strongly associated with obesity and cardiovascular risk factors, enhancing the risk of atherosclerosis. Thirty-two adolescents with newly diagnosed PCOS were evaluated for lipid profile disorders, insulin resistance, inflammation, non-alcoholic fatty liver disease (NAFLD), and subclinical atherosclerosis through measurements of carotid intima–media thickness (cIMT). The relationships of the above markers with increased body mass index and abdominal obesity were investigated. Twenty-three adolescents (72%) were overweight (OW) or obese (OB). The OW/OB group had significantly higher insulin, HOMA-IR, high-sensitive C-reactive protein (hsCRP), visceral adiposity index (VAI), and lipid accumulation product (LAP) levels; and lower glucose-per-insulin ratios and HDL-C levels compared to the healthy weight group. The cIMT and small dense low-density lipoprotein cholesterol (sdLDL-C) levels did not differ between the two groups. Similarly, cIMT and sdLDL-C levels did not differ between PCOS-adolescents and healthy controls. CIMT was positively correlated with systolic blood pressure and waist circumference per height ratio. In conclusion, OW/OB PCOS-adolescents have a cluster of adverse factors predisposing them to atherosclerotic cardiovascular disease. Therefore, early cardiovascular risk assessment, as well as timely and targeted interventions, are necessary for prevention.

Abstract
Glucocorticoids (GCs) remain the cornerstone of childhood acute lymphoblastic leukemia (chALL) therapy, exerting their cytotoxic effects through binding and activating of the glucocorticoid receptor (GR). GAS5 lncRNA acts as a potent riborepressor of GR transcriptional activity, and thus targeting GAS5 in GC-treated chALL could provide further insights into GC resistance and support personalized treatment decisions. Herein, to study the clinical utility of GAS5 in chALL prognosis and chemotherapy response, GAS5 expression was quantified by RT-qPCR in bone marrow samples of chB-ALL patients at diagnosis (n = 164) and at end-of-induction (n = 109), treated with ALL-BFM protocol. Patients' relapse and death were used as clinical end-points for survival analysis. Bootstrap analysis was performed for internal validation, and decision curve analysis assessed the clinical net benefit for chALL prognosis. Our findings demonstrated the elevated GAS5 levels in blasts of chALL patients compared to controls and the significantly higher risk for short-term relapse and poor treatment outcome of patients overexpressing GAS5, independently of their clinicopathological data. The unfavorable prognostic value of GAS5 overexpression was strongly validated in the high-risk/stem-cell transplantation subgroup. Finally, multivariate models incorporating GAS5 levels resulted in superior risk stratification and clinical benefit for chALL prognostication, supporting personalized prognosis and precision medicine decisions in chALL.

Abstract
OBJECTIVE To investigate the association of serum vitamin D and nasal secretion antimicrobial peptides (AMPs) levels with the severity of acute bronchiolitis. STUDY DESIGN We conducted a prospective single pediatric tertiary care center cohort study of inpatients aged 0-18 months with a first episode of acute bronchiolitis from November 1st 2014 to April 30th 2017. Disease severity was determined by the length of hospitalization and supplemental hospital data. Qualitative measurements included serum 25(OH)D and nasal secretion LL-37 and β-defensin-2 levels. Correlations were examined with the Mann-Whitney and Kruskal-Wallis criteria for qualitative and the correlation coefficient Spearman's rho for quantitative factors. Multiple linear and logarithmic regression were performed to adjust for confounding factors. RESULTS The study population consisted of 153 infants and toddlers with median age 3.1 months (interquartile range:1.6-4.9). No association was found between serum 25(OH)D and AMPs nasal secretions levels. Serum 25(OH)D and nasal secretion β-defensin-2 levels were not associated with the severity of bronchiolitis. In contrast, LL-37 levels were inversely associated with the length of hospitalization (rho = -0.340, p = .001), the need for medication use (p = .001), as well as the duration of oxygen supplementation (rho = -0.339, p = .001), and intravenous fluid administration (rho = -0.323, p = .001). This association remained significant after adjustment for potential confounders. CONCLUSION A significant association between LL-37 nasal secretions levels with the severity of acute bronchiolitis was found in hospitalized infants and toddlers. The role of LL-37 in the pathogenesis of bronchiolitis merits further investigation.

Abstract
Carotid intima-media thickness (cIMT) has been proposed as an early marker of subclinical atherosclerosis in high risk children. Children with heterozygous familial hypercholesterolemia have greater cIMT than matched healthy controls or their unaffected siblings. Statin therapy may delay the progression of cIMT, although long-term studies in children are scarce. We evaluated the effect of atorvastatin treatment on cIMT in children with dyslipidemia. We studied 81 children/adolescents, 27 with severe dyslipidemia (low-density lipoprotein cholesterol [LDL-C] ≥190 mg/dL) and 54 sex- and age-matched healthy controls; LDL-C ≤ 130 mg/dL and lipoprotein (a), Lp(a), ≤30 mg/dL. In the children with dyslipidemia, cIMT was measured twice, before and on treatment (18.2 ± 7.7 months). Anthropometric data, a full lipid profile, liver, kidney, and thyroid function were evaluated. Males with dyslipidemia had a greater cIMT than male controls after adjustment for other factors (P = .049). In addition, a nonstatistically significant decrease in cIMT was observed after treatment (P = .261). Treatment with atorvastatin resulted in a significantly improved lipid profile. Females with dyslipidemia had a significantly thinner cIMT than males. Children with normal and high Lp(a) levels had similar cIMT values. In conclusion, treatment with atorvastatin had a beneficial effect on the lipid profile and cIMT progression in children with severe dyslipidemia.

Abstract
AIM Fatty acid-binding protein-4 (FABP4) is an adipokine associated with obesity and signs of the metabolic syndrome. We aimed to investigate at birth in term neonates with normal and abnormal intrauterine growth concentrations of FABP4 and associate them with various perinatal parameters. METHODS Serum cord blood FABP4 levels were prospectively determined by ELISA in 80 singleton term appropriate-for-gestational-age (AGA), intrauterine growth-restricted (IUGR) and large-for-gestational-age (LGA) neonates. RESULTS Compared to the AGA group, cord blood FABP4 levels were increased in the IUGR and LGA groups. Additionally, they were higher in early-term than full-term neonates. A significant U-shaped correlation was recorded between serum FABP4 levels and birthweight. A significant negative correlation between cord blood FABP4 and gestational age in the whole study population was noted. CONCLUSION Cord blood FABP4 levels were significantly higher at the extremes of foetal growth at term and negatively correlated with gestational age, being increased in early-term versus full-term neonates. Further longitudinal studies with larger sample sizes are required to elucidate FABP4 implication in foetal growth and its association with future adverse cardiometabolic outcomes in the offspring.

Abstract
Background Risk-adjusted treatment has led to outstanding improvements of the remission and survival rates of childhood acute lymphoblastic leukemia (ALL). Nevertheless, overtreatment-related toxicity and resistance to therapy have not been fully prevented. In the present study, we evaluated for the first time the clinical impact of the apoptosis-related BCL2L12 gene in prognosis and risk stratification of BFM-treated childhood ALL. Methods Bone marrow specimens were obtained from childhood ALL patients upon disease diagnosis and the end-of-induction (EoI; day 33) of the BFM protocol, as well as from control children. Following total RNA extraction and reverse transcription, BCL2L12 expression levels were determined by qPCR. Patients' cytogenetics, immunophenotyping and minimal residual disease (MRD) evaluation were performed according to the international guidelines. Results BCL2L12 expression was significantly increased in childhood ALL and correlated with higher BCL2/BAX expression ratio and favorable disease markers. More importantly, BCL2L12 expression was associated with disease remission, while the reduced BCL2L12 expression was able to predict patients' poor response to BFM therapy, in terms of M2-M3 response and MRD≥0.1% on day 15. The survival analysis confirmed the significantly higher risk of the BFM-treated patients underexpressing BCL2L12 at disease diagnosis for early relapse and worse survival. Lastly, evaluation of BCL2L12 expression clearly strengthened the prognostic value of the established disease prognostic markers, leading to superior prediction of patients' outcome and improved specificity of BFM risk stratification. Conclusions The expression levels of the apoptosis-related BCL2L12 predict response to treatment and survival outcome of childhood ALL patients receiving BFM chemotherapy.

Abstract
BACKGROUND Lipocalin-2 (LCN-2) has been identified as an osteoblast-secreted hormone regulating immunity, inflammation and metabolic homeostasis and has emerged as a diagnostic and prognostic biomarker for acute kidney injury in neonates. We investigated the impact of fetal growth on antepartum maternal serum, cord serum and breast milk LCN-2 concentrations and the associations of the latter with perinatal parameters. METHODS Maternal serum, cord serum and breast milk LCN-2 concentrations were measured by ELISA in samples from 80 mothers who delivered 40 appropriate (AGA), 20 large for gestational age (LGA) and 20 intrauterine growth restricted (IUGR) neonates, classified by customized weight centiles. LCN-2 concentrations were associated with birth weight, customized centile, gender, maternal age and delivery mode. RESULTS Antepartum maternal serum LCN-2 concentrations were significantly higher in women delivering AGA infants compared to the other two groups. Cord blood LCN-2 concentrations were significantly higher compared to maternal ones; furthermore, they were significantly elevated in the IUGR group compared to the LGA one (p = .019). Lowest concentrations were detected in breast milk, which did not differ between the three growth groups. A negative correlation was documented between cord blood LCN-2 concentrations and customized centiles (r: -0.304, p = .007). CONCLUSIONS The higher cord serum LCN-2 concentrations, compared to maternal ones, may point to its fetal origin and potential role in intrauterine growth. The negative correlation of cord LCN-2 concentrations with customized centiles, possibly implies reduced nephron endowment/subclinical kidney damage in IUGR neonates. The extremely low LCN-2 breast milk concentrations could imply that the secretion of LCN-2 from maternal circulation to breast milk is not influenced by factors leading to intrauterine growth pathology.

Abstract
Objective: Lactation is associated with a dramatic increase of maternal bone turnover, leading to a reversible bone loss. Early life nutrition may influence later osteoporosis risk. Proteins synthesized by the group of wingless (Wnt) genes are key mediators of osteoblastogenesis and bone formation. We aimed to investigate maternal milk and serum concentrations of the inhibitors of the Wnt signaling pathway, Dickkopf-1 (DKK-1) and sclerostin.Material and methods: In 80 women, maternal milk and serum concentrations of DKK-1 and sclerostin were determined by ELISA on the 3rd-4th day postpartum. Concentrations were associated with various maternal, gestational and neonatal characteristics.Results: DKK-1 and sclerostin were detectable in early milk [mean ± SD: 817.17 ± 259.61 pg/mL, median (range) 258.04 (2452.40-53.17) pg/mL, respectively] at significantly lower concentrations than in maternal serum [mean ± SD: 3375.36 ± 416.75 pg/mL, median (range) 16 200.54 (58 832.00-3012.60) pg/mL, respectively], (p < .000). Maternal milk sclerostin concentrations positively correlated with respective serum ones (r = 0.599, p = .000). Maternal serum and milk sclerostin concentrations positively correlated with maternal body mass index (r = 0.37, p = .001 and r =0.38, p = .000, respectively), while maternal serum sclerostin concentrations were higher in primiparas (p = .002).Conclusion: DKK-1 and sclerostin are present in early human milk at significantly lower concentrations, compared with maternal serum, probably contributing to the short- and long-term benefits of mother's milk for bone health. Moreover, the large amounts of both substances in maternal serum may represent disruption of the Wnt cascade, contributing to the well-known lactation-associated bone loss, which seems to be greater in primiparas and obese mothers.

Abstract
BACKGROUND The oxidation of low-density lipoprotein (LDL; oxLDL) appears to play a key role in the early development of atherosclerosis. Increased serum antibodies against the oxLDL (anti-oxLDL antibodies) have been found in adults with atherosclerotic disease, as well as in healthy adults. The clinical significance and its precise role (atherogenic or atheroprotective), however, have not yet been clarified. This aim of this study was therefore to evaluate anti-oxLDL antibodies in healthy children and adolescents with and without hypercholesterolemia. METHODS The study involved 312 subjects, aged 4-18 years, 141 with LDL cholesterol (LDL-C) ≥130 mg/dL and 171 with acceptable LDL-C (<110 mg/dL). Total anti-oxLDL antibodies, total cholesterol, LDL-C and high-density lipoprotein cholesterol, triglycerides, apolipoproteins A1 and B, lipoprotein (a) and high-sensitivity C-reactive protein were measured in fasting serum. The anti-oxLDL antibodies were measured on enzyme-linked immunosorbent assay. RESULTS Anti-oxLDL antibodies were similar in the hypercholesterolemia and non-hypercholesterolemia groups. Girls had significantly higher anti-oxLDL antibodies compared with boys. There was no significant correlation of antibodies with age or body mass index. Increased apolipoprotein B was an important factor for lower anti-oxLDL antibodies, while all other parameters had no significant association with anti-oxLDL antibodies. CONCLUSION In children and adolescents with hypercholesterolemia, total anti-oxLDL antibodies cannot serve as a marker for risk for atherosclerosis or for future cardiovascular disease.

Abstract
BACKGROUND Despite the favourable survival rates of childhood acute lymphoblastic leukaemia (ALL), a significant number of patients present resistance to antileukaemic agents and dismal prognosis. In this study, we analysed miR-125b expression in childhood ALL and evaluated its clinical utility for patients treated with Berlin-Frankfurt-Münster (BFM) protocol. METHODS The study included 272 bone marrow specimens obtained on diagnosis and on BFM day 33 from 125 patients and 64 healthy children. Following extraction, RNA was polyadenylated and reverse transcribed. miR-125b levels were quantified by quantitative PCR. Cytogenetics, immunohistotype and MRD were analysed according to international guidelines. RESULTS Downregulated miR-125b levels were detected in childhood ALL patients and correlated with adverse prognosis. Following BFM induction, miR-125b levels were significantly increased, however, elevated day 33/diagnosis miR-125b ratio was associated with unfavourable disease features. Loss of miR-125b during diagnosis and higher day 33/diagnosis ratio were correlated with stronger risk for disease short-term relapse and patients' worse survival. Moreover, multivariate regression models highlighted the independent prognostic value of miR-125b for childhood ALL. Finally, the combination of miR-125b with clinically used disease markers clearly enhanced the prediction of patients' resistance to BFM chemotherapy. CONCLUSIONS miR-125b significantly improves the prognosis of childhood ALL patients' outcome under BFM treatment.

Abstract
BACKGROUND In the present study we investigated the levels of proapoptotic caspase-9 and antiapoptotic Bcl-2 proteins in the sera of children and adolescents with idiopathic epilepsy and tried to relate the findings to the patients' clinical parameters. METHODS This retrospective study consisted of 118 children and adolescents with idiopathic epilepsy, categorized according to type and number of seizures, duration of the disease and the control of seizures and 30 age- and sex-matched controls. The relapse of seizures was taken into consideration. RESULTS Mean serum level between Bcl-2 and caspase-9 was significantly higher only in Bcl-2 patients, compared to controls (P≤0.0001) and (P=0.987) respectively. Significant difference in Bcl-2 level was found among the different types of focal seizures. Caspase-9 level was statistically different in patients with two or more seizures per month compared to those with one seizure per month (P=0.048). No correlation was found between Bcl-2 and caspase-9 levels and age, gender, seizure frequency, total number of seizures and the duration of epilepsy. No significant difference was found in patients with and without drug treatment. CONCLUSIONS Bcl-2 displays an association with apoptosis and highlights the potential of being a surrogate biomarker for active seizures and epilepsy. There is a significant difference in Bcl-2 serum level among the different types of focal seizures. Proapoptotic caspase-9 cannot act as a marker of active seizures and epilepsy. Caspase-9 serum level is increased acutely in controlled cases after a single relapse.

Abstract
Background Increased plasma Urotensin II (UII) levels have been found in adults with renal diseases. Studies in children are scarce. The objective of the study is to estimate plasma UII levels in subjects with chronic kidney disease (CKD) stages 3 to 5 and renal transplant recipients (RTR). In addition, the correlation of UII with anthropometric features and biochemical parameters was assessed. Methods Fifty-four subjects, aged 3 to 20 years old, 23 with CKD, 13 with end-stage kidney disease (ESKD) undergoing hemodialysis (HD) and 18 RTR were enrolled. A detailed clinical evaluation was performed. Biochemical parameters of renal and liver function were measured. Plasma UII levels were measured in all patients and in 117 healthy controls, using a high sensitive enzyme immunoassay (EIA) kit. All data were analyzed using STATA™ (Version 10.1). Results Median UII and mean log-transformed UII levels were significantly higher in CKD and RTR patients compared to healthy subjects (p < 0.001). HD patients had higher but not statistically significant UII and log-UII levels than controls. UII levels increased significantly at the end of the HD session and were higher than controls and in line to those of other patients. The geometric scores of UII in HD (before dialysis), CKD and RTR patients increased respectively by 42, 136 and 164% in comparison with controls. Metabolic acidosis was associated with statistical significant change in log-UII levels (p = 0.001). Patients with metabolic acidosis had an increase in UII concentration by 76% compared to those without acidosis. Conclusions Children and adolescents with CKD, particularly those who are not on HD and RTR, have significantly higher levels of UII than healthy subjects. UII levels increase significantly at the end of the HD session. The presence of metabolic acidosis affects significantly plasma UII levels.

Abstract
OBJECTIVE Fetal macrosomia is associated with cardiac hypertrophy and increased cardiovascular risk. Cardiac biomarkers may play diagnostic/prognostic role in cardiovascular disease. We tested whether cardiac biomarkers are differentially expressed in cord blood samples of full-term singleton large-for-gestational-age (LGA), as compared to appropriate-for-gestational-age (AGA) pregnancies. METHODS Cardiotrophin-1 (CT-1), Titin, pentraxin (PTX-3) and soluble CD36 (sCD36) concentrations were determined in 80 cord blood samples from a) LGA pregnancies due to maternal diabetes (n = 8), overweight/obese (n = 11), excessive weight gain (n = 7), without specific pathology (n = 14), b) AGA normal pregnancies (controls, n = 40). Neonates were classified as LGA or AGA based on customized birth weight (BW) standards. RESULTS CT-1 and Titin concentrations were higher in LGA than AGA pregnancies (p < .001 and p = .023, respectively). A subgroup analysis (in the LGA group) showed increased CT-1 concentrations only in diabetic pregnancies. PTX-3 and sCD36 concentrations were similar in LGA and AGA fetuses. In the LGA group, PTX-3 concentrations positively correlated with birth-weight (r = .416, p = .008) and respective sCD36 concentrations (r = .443, p = .004). CONCLUSION Higher Titin concentrations in LGAs possibly represent a candidate molecular mechanism underlying the association between fetal macrosomia and cardiomyocyte/diastolic dysfunction. CT-1 is up-regulated only in LGAs exposed to maternal diabetes. PTX-3 and sCD36 are probably not affected by excessive fetal growth.

Abstract
UNLABELLED Higher levels of Dickkopf-1, which is an inhibitor of Wnt/β-catenin bone metabolic pathway, could be indicative of downregulated Wnt system, with possible lower osteoblast activation and higher osteoclast signaling in type 1 diabetes mellitus children and adolescents. Dickkopf-1 could significantly contribute to diabetes osteopathy. INTRODUCTION Increased fracture risk and elevated Dickkopf-1 levels, which is an inhibitor of Wnt/β-catenin bone metabolic pathway, have been documented in adult patients with type 2 diabetes mellitus (T2D), while no relevant data exist on childhood type 1 diabetes (T1D). Our aim was to study plasma Dickkopf-1 distribution in children and adolescents with T1D and to correlate Dickkopf-1 with metabolic bone markers and bone mineral density (BMD). METHODS We evaluated 40 children and adolescents with T1D (mean ± SD age 13.04 ± 3.53 years, T1D duration 5.15 ± 3.33 years) and 40 healthy age-matched and gender-matched controls (age 12.99 ± 3.3 years). Dickkopf-1 and bone metabolic markers were measured, while total body and lumbar spine BMD were evaluated with dual-energy X-ray absorptiometry (DXA). RESULTS Dickkopf-1 demonstrated a Gaussian distribution, with higher levels in T1D patients (13.56 ± 5.34 vs 11.35 ± 3.76 pmol/L, p = 0.024). Higher values were found in boys and in prepubertal children. Dickkopf-1 correlated positively with osteoprotegerin and fasting glucose in patients, while positive correlation with sclerostin and total soluble receptor activator of nuclear factor-kappaB ligand (s-RANKL) was found in controls. Positive correlations with C-telopeptide cross-links (CTX), osteocalcin, alkaline phosphatase, phosphate, and insulin-like growth factor 1 (IGF1) were documented in both groups. Lumbar spine Z-score was positively associated with Dickkopf-1 in controls, while a negative trend was found in patients. CONCLUSIONS Higher levels of Dickkopf-1 could indicate a downregulated Wnt/β-catenin system with possible lower osteoblast activation and higher osteoclast signaling in T1D children and adolescents. Dickkopf-1 could possibly be a significant contributor of T1D osteopathy. Future therapies could focus on Wnt/β-catenin metabolic pathway.

Abstract
BACKGROUND To identify potential biomarkers in the 1st trimester of pregnancy for the identification of women destined to develop early onset preeclampsia (EOPE). METHODS Blood samples were obtained from pregnant women at 11-13 weeks of gestation. Women were followed up until delivery. Five samples from EOPE complicated pregnancies and 5 from unaffected ones were analysed using 2-DE and MALDI-TOF-TOF MS/MS. The altered expression of selected proteins was verified by ELISA in an extended sample cohort. RESULTS Twelve proteins were differentially expressed in the plasma of women who subsequently developed EOPE as compared to controls. Alpha-1-antitrypsin (A1AT), CD5 antigen-like molecule (CD5L) Keratin, type I cytoskeletal 9 (K1C9), Myeloid cell nuclear differentiation antigen (MNDA), Transferrin (TRFE) and Vitamin D-binding protein (VTDB) were up-regulated with fold changes 3.14, 2.18, 1.53, 1.53, 4.26 3.38 respectively, whereas Alpha-2-HS-glycoprotein (FETUA), Beta-2-glycoprotein 1 (APOH), Complement factor B (CFAB), Haptoglobin (HPT), Vitronectin (VTNC) and Zinc-alpha-2-glycoprotein (ZA2G) were down-regulated with fold changes -0.38, -0.76, -0.24, -0.47, -0.23, and -0.50 respectively. The down-regulation of APOH, VTNC and HPT was verified using ELISA. CONCLUSIONS The differentially expressed proteins represent potential biomarkers for the early screening for EOPE. Follow-up experiments however are necessary for evaluation.

Abstract
The objective of this study was to investigate circulating levels of cystatin C (an important endogenous marker of renal function) in mothers, fetuses, and neonates from intrauterine growth-restricted (IUGR; characterized by impaired nephrogenesis) and appropriate-for-gestational-age (AGA) pregnancies. Serum cystatin C levels were measured by enzyme immunoassay in 40 parturients and their 20 IUGR (<or=3rd customized centile, due to gestational pathology) and 20 AGA fetuses and neonates on postnatal day 1 (N1) and 4 (N4). Comparatively, creatinine and urea concentrations were determined in the same samples. Fetal cystatin C levels were higher in the AGA than the IUGR group (P = .001). In both groups, maternal cystatin C levels were lower than fetal (P < .001), N1 (P < .001), and N4 (P < .001) levels. Fetal levels were higher than N1 (P < .001) and N4 (P < .001), and N1 levels were higher than N4 (P = .007) ones. In both groups, no correlation existed between maternal and fetal levels, but positive correlations were found between cystatin C, creatinine, and urea levels in maternal and neonatal samples (in all cases, r >or= 0.376 and P <or= .045). Cystatin C levels did not correlate with gestational age and did not differ between males and females. Fetal cystatin C serum levels are lower in the IUGR group, significantly decrease after birth, and do not correlate with maternal levels in both groups. In addition, serum cystatin C levels positively correlate with respective creatinine and urea levels in the perinatal period.

Abstract
BACKGROUND AND OBJECTIVE Sclerostin is an inhibitor of the Wnt/beta-catenin bone metabolic pathway. Increased sclerostin levels and reduced bone mineral density (BMD) have been documented in adult patients with diabetes mellitus (DM), predominantly in those with type 2 diabetes mellitus (T2DM). No relative data exist on childhood type 1 diabetes mellitus (T1DM). Our objective was to study plasma sclerostin in T1DM children and adolescents and controls and its correlations with metabolic bone markers and BMD. SUBJECTS AND METHODS This was a cross-sectional study that was conducted at an outpatient clinical center. Forty T1DM children and adolescents were evaluated (mean ± SD age: 13.04 ± 3.53 yr, T1DM duration: 5.15 ± 3.33 yr), along with 40 healthy matched controls (age 12.99 ± 3.3 yr). Sclerostin, soluble receptor activator of nuclear factor-kappaB ligand (s-RANKL), osteoprotegerin, osteocalcin, C-telopeptide crosslinks, electrolytes, parathyroid hormone (PTH), and total 25(OH)D were measured. Lumbar and subcranial total body BMD were evaluated with dual energy X-ray absorptiometry (DXA). RESULTS Sclerostin levels demonstrated a Gaussian distribution, with no significant difference between patients and controls (51.56 ± 12.05 vs. 50.98 ± 13.55 pmol/L, p = 0.84). Significantly lower values were found in girls and prepubertal children. Sclerostin values were significantly and gradually increased in children through pubertal Tanner stages 1-3, were reduced at stage 4 and increased again at pubertal stage 5. Sclerostin levels were positively correlated with logCTX (logarithm of C-terminal telopeptide crosslinks of type I collagen), logOsteocalcin (logarithm of Osteocalcin), magnesium, total body, and L1-L4 BMD z-score. CONCLUSIONS T1DM patients had similar levels of sclerostin with controls. Sclerostin correlated with bone resorption and formation markers and also with bone mass indices, gender, and pubertal stage. The decrease in sclerostin values observed in pubertal stage 4 adolescents coincides with the concurrent growth spurt, and is consistent with sclerostin physiology as an inhibiting signal.

Abstract
OBJECTIVE To determine maternal colostrum/serum concentrations of the bioactive substances irisin, adropin and copeptin and investigate their association with several perinatal parameters and pathologic conditions during pregnancy. METHODS In a cohort of 81 mothers with full-term deliveries, colostrum/serum concentrations of irisin, adropin and copeptin were prospectively evaluated by ELISA on Day 3-4 postpartum. RESULTS Copeptin and adropin were detectable in human colostrum at higher, while irisin at lower concentrations than in maternal serum (p < 0.001 in all cases). Colostrum adropin and copeptin concentrations positively correlated with maternal serum ones (r = 0.421, p < 0.001 and r = 0.304, p = 0.006, respectively). CONCLUSIONS Irisin, adropin and copeptin are present in colostrum and we speculate that they may be implicated in postnatal adaptation with respect to thermoregulation, vascular adaptation, glucose metabolism, lung function and fluid homeostasis. These findings may possibly enhance the necessity for early breastfeeding, particularly of infants born by cesarean section, who are prone to hypothermia, breathing disorders and dehydration.

Abstract
UNLABELLED Simultaneous lower bone mineral density, metabolic bone markers, parathyroid hormone (PTH), magnesium, insulin-like growth factor 1 (IGF1), and higher levels of total soluble receptor activator of nuclear factor-kappa B ligand (s-RANKL), osteoprotegerin (OPG), and alkaline phosphatase (ALP) are indicative of lower osteoblast and increased osteoclast signaling in children and adolescents with type 1 diabetes mellitus, predisposing to adult osteopenia and osteoporosis. INTRODUCTION Type 1 diabetes mellitus (T1DM) is a risk factor for reduced bone mass, disrupting several bone metabolic pathways. We aimed at identifying association patterns between bone metabolic markers, particularly OPG, s-RANKL, and bone mineral density (BMD) in T1DM children and adolescents, in order to study possible underlying pathophysiologic mechanisms of bone loss. METHODS We evaluated 40 children and adolescents with T1DM (mean ± SD age 13.04 ± 3.53 years, T1DM duration 5.15 ± 3.33 years) and 40 healthy age- and gender-matched controls (aged12.99 ± 3.3 years). OPG, s-RANKL, osteocalcin, C-telopeptide cross-links (CTX), IGF1, electrolytes, PTH, and total 25(OH)D were measured, and total body along with lumbar spine BMD were evaluated with dual energy X-ray absorptiometry (DXA). Multivariate regression and factor analysis were performed after classic inference. RESULTS Patients had significantly lower BMD, with lower bone turnover markers, PTH, magnesium, and IGF1 than controls, indicating lower osteoblast signaling. Higher levels of total s-RANKL, OPG, and total ALP were observed in patients, with log(s-RANKL) and OPG correlation found only in controls, possibly indicating increased osteoclast signaling in patients. Coupling of bone resorption and formation was observed in both groups. Multivariate regression confirmed simultaneous lower bone turnover, IGF1, magnesium, and higher total s-RANKL, OPG, and ALP in patients, while factor analysis indicated possible activation of RANK/RANKL/OPG system in patients and its association with magnesium and IGF1. Patients with longer disease duration or worse metabolic control had lower BMD. CONCLUSIONS T1DM children and adolescents have impaired bone metabolism which seems to be multifactorial. Reduced osteoblast and increased osteoclast signaling, resulting from multiple simultaneous disturbances, could lead to reduced peak bone accrual in early adulthood, predisposing to adult osteopenia and osteoporosis.

Abstract
OBJECTIVE To prospectively investigate maternal concentrations of the myokine irisin in large for gestational age (LGA) and intrauterine growth restricted (IUGR) versus appropriate for gestational age (AGA) normal pregnancies and associate them with various perinatal parameters. METHODS Plasma irisin and insulin concentrations were measured by enzyme-linked immunosorbent assay (ELISA) and immunoradiometric assay (IRMA), respectively, in a cohort of 80 mothers delivering LGA (n = 30), IUGR (n = 30) and AGA (n = 20) singleton full-term infants. RESULTS Maternal irisin concentrations were similar among LGA, IUGR and AGA groups and did not correlate with respective insulin ones or maternal body mass index. In a combined group, maternal irisin concentrations decreased with advancing gestational age (p < 0.001) and were lower in multi-, compared to nulliparous women (p = 0.004). In the IUGR group, maternal irisin concentrations were higher in cases of smoking (p = 0.006). CONCLUSIONS Irisin may not be differentially regulated in insulin resistance-associated pregnancy disorders resulting in fetal macrosomia and IUGR. Maternal irisin down-regulation with advancing gestation could possibly contribute to the observed maternal fat accumulation and progressive insulin resistance towards term. Similarly, lower maternal irisin concentrations in multiparous women may reflect the documented positive association between parity and fat deposition. Irisin up-regulation in cases of smoking may indicate the need for enhanced oxygen consumption to maintain energy production under conditions of hypoxia.

Abstract
BACKGROUND/AIMS Irisin, a novel myokine with antiobesity properties, drives brown-fat-like conversion of white adipose tissue, thus increasing energy expenditure and improving glucose tolerance. We aimed to investigate circulating irisin concentrations in large-for-gestational-age (LGA) and intrauterine-growth-restricted (IUGR) fetuses, both associated with metabolic dysregulation and long-term susceptibility to obesity and metabolic syndrome development. METHODS Plasma irisin and insulin concentrations were determined by ELISA and IRMA, respectively, in 80 mixed arteriovenous cord blood samples from LGA (n=30), IUGR (n=30) and appropriate-for-gestational-age (AGA, n=20) singleton full-term pregnancies. Fetuses were classified as LGA, IUGR or AGA, based on customized birth-weight standards adjusted for significant determinants of fetal growth. RESULTS Fetal irisin concentrations were lower in IUGR cases than AGA controls (p=0.031). Cord blood irisin concentrations were similar in LGA and AGA groups and positively correlated with birth-weight, as well as customized centiles (r=0.245, p=0.029 and r=0.247, p=0.027, respectively). Insulin concentrations were higher in LGA, compared to AGA fetuses (p=0.036). In the LGA group, fetal irisin concentrations positively correlated with fetal insulin concentrations (r=0.374, p=0.042). CONCLUSIONS Impaired skeletal muscle metabolism in IUGR fetuses may account for their irisin deficiency, which may be part of the fetal programming process, leading to increased susceptibility to later metabolic syndrome development. Furthermore, irisin down-regulation may predispose IUGR infants to hypothermia at birth, by inducing less "browning" of their adipose tissue and consequently less non-shivering thermogenesis. Irisin upregulation with increasing birth-weight may contribute to a slower fat gain during early infancy ("catch-down"), by promoting higher total energy expenditure. The positive correlation between irisin and insulin in the LGA group may reflect a counterbalance of the documented hyperinsulinemia, which is partly responsible for the excessive fat deposition in the LGA fetus.

Abstract
OBJECTIVE To determine levels of adropin (implicated in insulin resistance and endothelial dysfunction) in intrauterine growth restricted (IUGR), large (LGA) and appropriate for gestational age (AGA) pregnancies. METHODS Cord-blood (UC) adropin and insulin concentrations were measured in 30 IUGR, 30 LGA and 20 AGA full-term infants and their mothers (MS). RESULTS No significant differences in adropin concentrations were observed between the three groups. In the IUGR group MS adropin was significantly decreased when neonates had higher birth weights [b = -0.003, 95% CI -0.006 to 0.0, p = 0.043]. In all groups, MS adropin levels were positively correlated with UC ones (r = 0.282, p = 0.011) and were significantly increased in female neonates [b = 0.977, 95% CI 0.122-1.832, p = 0.026]. In the LGA group, MS insulin was negatively correlated with UC adropin (r = -0.362 p = 0.049). CONCLUSIONS Increased maternal adropin levels in severe IUGR cases might represent a regulatory feedback mechanism against endothelial placental dysfunction. The positive correlation between maternal and umbilical cord adropin levels implies its transplacental transfer. Increased maternal adropin levels in female neonates could be attributed to interaction of adropin with fetal estrogens through vascular endothelial growth factor (VEGF). The negative correlation between maternal insulin and fetal adropin levels in the LGA group is probably attributed to their respective insulin resistance.

Abstract
UNLABELLED Backround: Reliable biological markers for the differentiation of asthma phenotypes in preschool children with wheezing are lacking. The purpose of the study is to assess the relationship of urinary Leukotriene E4 (U-LTE4) to particular asthma phenotypes in preschool children with recurrent episodic (viral) wheezing following upper respiratory tract infections with or without atopic predisposition. METHODS Ninety-six preschool patients with recurrent episodic wheezing participated, 52 atopic and 44 non-atopic, during exacerbation and in remission. Exacerbation was defined on clinical basis (wheeze in the presence of coryzal symptoms). Atopy was determined by specific serum IgE measurement and skin-prick testing. U-LTE4 was determined by enzyme immunoassay. Thirty-six age-matched, non-asthmatic, non-atopic children served as controls. RESULTS During exacerbation, U-LTE4 was significantly higher in all children with recurrent episodic wheezing in comparison to A: Remission: 642.20 ± 268 versus 399.45 ± 204, p value <0.001 and B: CONTROLS 642.20 ± 268 versus 271.39 ± 83, p value <0.001. Atopic patients demonstrated significantly higher levels of U-LTE4 compared to non-atopic, both during exacerbation 872.13 ± 246 versus 613.15 ± 150, p value = 0.0013 and during remission 507.59 ± 182 versus 283.59 ± 160, p value <0.001. During remission, a highly significant difference of U-LTE4 was found when controls were compared to atopic patients: 271.39 ± 83 versus 507.59 ± 182, p value = 0.002 but not when compared to non-atopic ones: 271.39 ± 83 versus 283.59 ± 160, p value = 0.432. CONCLUSION U-LTE4 is strongly associated with the acute wheeze episode in preschool children, more so in atopics. Increased basal levels of U-LTE4 occur only in atopics. This suggests a potential role of U-LTE4 as a marker of atopic, virus-induced asthma in preschool children.

Abstract
AIM This study investigated breast milk and maternal serum concentrations of biochemical markers of bone resorption, which may be implicated in both maternal and neonatal bone metabolism. METHODS Tests were carried out on 85 parturients 3-4 days after they gave birth. We measured their breast milk and serum concentrations for soluble receptor activator of nuclear factor kappaB ligand (sRANKL) and cross-linked N-telopeptide of type I collagen (NTx). The sRANKL and NTx concentrations were associated with several perinatal parameters. RESULTS Soluble receptor activator of nuclear factor kappaB ligand was detectable in breast milk at considerably lower concentrations than in maternal serum (p < 0.001), and these breast milk sRANKL concentrations were decreased in maternal diabetes (b = -0.366, 95% CI -0.622 to -0.110, p = 0.006). Breast milk NTx concentrations were higher in exclusive lactation (b = 0.269, 95% CI 0.014-0.524, p = 0.039), but lower in Caesarean sections (b = -0.224, 95% CI -0.428 to -0.019, p = 0.032). CONCLUSION Soluble receptor activator of nuclear factor kappaB ligand is downregulated in breast milk, particularly in the case of diabetes. Breast milk NTx upregulation characterises exclusive lactation, and its downregulation characterises Caesarean section deliveries. Nutritional interventions in foetal life and early infancy may programme adult bone health and ameliorate diseases with developmental origins, such as osteoporosis.

Abstract
Background Small dense low density lipoprotein-cholesterol (sdLDL-C) molecules are more atherogenic compared with large buoyant ones. Phytosterols-enriched diets are effective in decreasing total cholesterol (TC) and low density lipoprotein-cholesterol (LDL-C) concentrations in hyperlipidemic children without significant adverse effects. Limited data on the impact of such a diet on sdLDL-C levels is available in adults while there are no reports concerning children. The purpose of this study is to prospectively evaluate the effect of the daily consumption of 2 g of plant sterols on sdLDL-C levels in children with hypercholesterolemia. Methods Fifty-nine children, 25 with LDL-C ≥ 3.4 mmol/l (130 mg/dl) and 34 with LDL-C < 3.4 mmol/l, aged 4.5-15.9 years, were included in the study. A yogurt-drink enriched with 2 g of plant sterols was added to the daily diet of hypercholesterolemic children and 6–12 months later lipid profiles were reassessed. Direct quantitative methods were used to measure LDL-C and sdLDL-C levels. Results The consumption of plant sterols reduced sdLDL-C significantly (p < 0.001), but levels remained higher compared with controls (p < 0.001). TC, LDL-C, non high density lipoprotein-cholesterol (NonHDL-C) and apolipoprotein B (ApoB) levels also decreased significantly (p < 0.05). The median reduction of sdLDL-C and LDL-C was 16.6% and 13%, respectively. These variables decreased >10% in sixteen children (64%), independently from baseline levels, sex, age and body mass index (BMI). High density lipoprotein-cholesterol (HDL-C), lipoprotein a [Lp(a)], and triglycerides (TGs) levels remained unaffected. Conclusions Plant sterols decrease sdLDL-C significantly and may be beneficial for children with hypercholesterolemia.

Abstract
OBJECTIVE To determine levels of the possible angioregulatory molecules netrin-1 and -4, in intrauterine-growth-restricted (IUGR), large for gestational age (LGA) (both groups characterized by altered angiogenic mechanisms) and appropriate-for-gestational-age (AGA) pregnancies. METHODS Cord blood (UC) netrin-1 and -4 concentrations were measured in 30 IUGR, 30 LGA and 20 AGA infants and their mothers (MS). RESULTS Netrin-1 and -4 concentrations did not differ in all groups. UC netrin-4 increased with gestational age (b = 0.075, 95% CI 0.029-0.121, p = 0.002). In the IUGR group, MS netrin-4 decreased as birth-weight centiles increased [b = -0.058, 95% CI -0.112 to -0.004, p = 0.036]. In the LGA group, MS netrin-1 decreased with advanced gestational age [b = -0.063, 95% CI -0.105 to -0.022, p = 0.004]. In all cases, MS netrin-1 positively correlated with MS netrin-4 (r = 0.299, p = 0.007), while UC netrin-1 negatively correlated with UC netrin-4 (r = -0.239, p = 0.033). CONCLUSIONS Increased UC netrin-4 levels with advancing gestational age may reflect its effect on fetal development. Decreased maternal netrin-1 levels in the LGA group possibly represent a negative feedback mechanism against increased angiogenesis. Increased maternal netrin-4 levels in IUGR neonates may reflect in utero hypoxia, while the negative correlations between fetal netrin-1 and -4 levels may exert the dynamic balance between their angio- and anti-angiogenic properties.

Abstract
BACKGROUND Hepcidin is a peptide hormone that plays a key role in regulating iron absorption from the small intestine and body iron distribution. Alterations in hepcidin concentrations have been associated with chronic inflammatory conditions or inherited diseases of iron metabolism. The aim of our study was to evaluate healthy children in order to define normal reference range of serum hepcidin concentrations. The universal use of a reliable commercial ELISA kit gives the ability to compare our results with those from previous studies. METHODS We evaluated 180 healthy children (88 boys, mean age: 67.55 ± 39.26 months, median: 60, range: 24-156 months) aged 2-12 years, using an immunoassay kit. RESULTS Hepcidin median values were 46.94 ng/ml for boys and 46.79 ng/ml for girls. No significant differences were observed between boys and girls. There seem to be significantly higher values of hepcidin in older children (10-12 years old). This trend was constant and statistically significant in boys after gender and age group stratification. Although this trend was more prominent in girls, it was not statistically significant. CONCLUSIONS This study aims at setting up reference values for serum hepcidin concentrations in healthy pediatric population by using a well-established laboratory kit. The difference in hepcidin concentrations in older children could be attributed to different growth rates. Additionally, differences between values in adults and children could reflect alterations in iron metabolism between those two age groups.

Abstract
OBJECTIVE To prospectively investigate the potential role of the lectin pathway of complement in intrauterine-growth-restriction (IUGR, associated with impaired immunocompetence and increased risk for neonatal infections), by determining cord blood concentrations of mannose-binding lectin (MBL), H-ficolin and L-ficolin (important mediators of neonatal innate immunity) in IUGR and appropriate for gestational age (AGA) pregnancies. Furthermore, we aimed to describe correlations among cord blood MBL, H- and L-ficolin concentrations and with several demographic parameters of the infants at birth. METHODS Serum MBL, H- and L-ficolin concentrations were determined by ELISA in 154 mixed arteriovenous cord blood samples from IUGR (n = 50) and AGA (n = 104) singleton full-term infants. RESULTS Cord blood MBL concentrations were significantly lower in IUGR cases than AGA controls (p = 0.029). No differences in cord blood H- and L-ficolin concentrations were observed between groups. In the IUGR group, cord blood MBL concentrations negatively correlated with respective L-ficolin ones (r = -0.442, p = 0.001). CONCLUSIONS The relatively decreased MBL expression in IUGR fetuses at term could possibly contribute to IUGR-associated neonatal immunodeficiency, predisposing to increased susceptibility to infections. The negative correlation between MBL and L-ficolin concentrations in the IUGR group might suggest an underlying immune variation and needs to be further investigated.

Abstract
The objective was to investigate circulating concentrations of bone formation markers (undercarboxylated osteocalcin [Glu-OC], an established marker of bone formation during fetal and early postnatal life], and Dickkopf-1 [DKK-1], a natural inhibitor of osteoblastogenesis during fetal development]) in intrauterine-growth-restricted (IUGR; associated with impaired fetal skeletal development) and appropriate-for-gestational-age (AGA) pregnancies. Circulating concentrations of Glu-OC and DKK-1 were determined by enzyme immunoassay in 40 mothers and their 20 asymmetric IUGR and 20 AGA singleton full-term fetuses and neonates on postnatal day 1 (N1) and 4 (N4). Parametric tests were applied in the statistical analysis. No significant differences in Glu-OC concentrations were observed between IUGR and AGA groups, whereas fetal DKK-1 concentrations were lower in the IUGR group (P = .028). In both groups, maternal Glu-OC and DKK-1 concentrations were lower than fetal, N1, and N4 concentrations (P ≤ .012 in all cases), whereas fetal Glu-OC concentrations were higher than N1 and N4 ones (P ≤ .037 in all cases). In addition, N1 Glu-OC concentrations were higher than N4 concentrations (P = .047). Finally, maternal Glu-OC and DKK-1 concentrations positively correlated with fetal, N1, and N4 ones (r ≥ 0.404, P ≤ .01 in all cases). Fetal/neonatal bone formation may not be impaired in full-term asymmetric IUGR infants, as indicated by the similar Glu-OC concentrations in both groups. Fetal DDK-1 concentrations are lower in the IUGR group, representing probably a compensatory mechanism, favoring the formation of mineralized bone. Fetal/neonatal bone turnover is markedly enhanced compared with maternal one and seems to be associated with the latter in both late pregnancy and early postpartum.

Abstract
The aim of this study was to investigate circulating concentrations of omentin-1 and vaspin (adipocytokines predominantly secreted by visceral adipose tissue and not yet investigated in perinatal life) in maternal, fetal, and neonatal samples from intrauterine growth-restricted (IUGR; associated with altered development of adipose tissue) and appropriate-for-gestational-age (AGA) pregnancies and to correlate them with the respective insulin concentrations. Serum omentin-1 and vaspin concentrations were determined by enzyme immunoassay in 40 mothers and their 20 IUGR and 20 AGA singleton full-term fetuses and neonates on postnatal day 1 (N1) and day 4 (N4). Both hormones were detectable in fetal and neonatal blood (omentin-1 [mean ± SD, in nanograms per milliliter]: AGA vs IUGR group--fetal: 11.32 ± 1.88 vs 10.47 ± 1.30, N1: 10.74 ± 1.42 vs 10.46 ± 1.54, and N4: 10.90 ± 2.72 vs 11.35 ± 3.92; vaspin [median, minimum-maximum; in nanograms per milliliter]: AGA vs IUGR group--fetal: 0.39 [0.04-19.06] vs 0.40 [0.05-1.34], N1: 0.40 [0.04-16.70] vs 0.44 [0.23-3.34], and N4: 0.49 [0.02-8.89] vs 0.55 [0.06-3.92]). No significant differences in omentin-1 or vaspin concentrations were observed between IUGR and AGA groups, whereas fetal and N1 insulin concentrations were lower in the former (P = .025 and P = .027, respectively). In both groups, fetal omentin-1 concentrations were higher (P ≤ .018), whereas vaspin concentrations were lower (P ≤ .001), than maternal ones. Furthermore, maternal vaspin concentrations were higher in cases of cesarean delivery (P = .024). Omentin-1 and vaspin concentrations did not correlate with the respective insulin ones. In conclusion, omentin-1 and vaspin are present in the fetus and neonate. Perinatal concentrations of omentin-1 and vaspin are similar in IUGR cases and AGA controls--despite lower insulin concentrations in the former--and do not correlate with the respective insulin concentrations. Higher omentin-1 concentrations in the fetus may be crucial to enhance a growth-promoting effect, whereas lower maternal vaspin concentrations in cases of vaginal delivery may be attributed to spontaneous term delivery inflammation.

Abstract
BACKGROUND Clara cell protein (CC16) is an immunomodulatory/anti-inflammatory broncho-alveolar-derived molecule and a biomarker of pulmonary epithelial cells maturity and alveolo-capillary membrane injury. Intrauterine growth-restricted (IUGR) neonates may present with structural lung immaturity, impaired immunocompetence and increased risk for respiratory infections and chronic obstructive lung disease in later life. OBJECTIVES To investigate circulating CC16 concentrations in maternal, fetal, and neonatal samples from IUGR and appropriate for gestational age (AGA) pregnancies. METHODS Serum CC16 concentrations were determined by EIA in 40 mothers and their 20 IUGR and 20 AGA singleton full-term fetuses-neonates on postnatal days 1 (N1) and 4 (N4). RESULTS No significant differences in CC16 concentrations were observed between IUGR and AGA groups. In both groups, maternal CC16 concentrations were lower compared to N1 and N4 ones (P < 0.001 in each case). Fetal CC16 concentrations were significantly lower compared to N1 and N4 ones (P < 0.001 in each case). In the AGA group, N1 CC16 concentrations were significantly higher than N4 ones (P < 0.001). Combining groups, N1 CC16 concentrations positively correlated with gestational age (r = 0.364, P = 0.021). Finally, the effect of gender, parity, and maternal age on CC16 concentrations was not significant. CONCLUSIONS The lack of differences in CC16 concentrations between IUGR and AGA groups possibly suggests that the lung immaturity and later respiratory diseases, associated with the former, may not be related to early CC16 deficiency. CC16 concentrations increase with advancing gestational age and peak on the first day of life, possibly indicating a vital role of the protein in fetal lung maturation and extrauterine pulmonary adaptation.

Abstract
OBJECTIVE To determine cord blood levels of calprotectin, a protein that is increased in inflammatory states and released by activated neutrophils has apoptosis-inducing activity. MATERIALS AND METHODS Cord-blood calprotectin concentrations were determined in intrauterine-growth-restricted (IUGR, usually associated with increased neutrophil activation and apoptosis, n=50) and appropriate-for-gestational-age (AGA, n=110) single full-term pregnancies, and were correlated with perinatal demographic parameters. RESULTS No significant differences exists between the IUGR and AGA groups, implying that calprotectin at birth does not reflect increased neutrophil activation and apoptosis expected in IUGR. However, in IUGRs, calprotectin concentrations increased with every gestational week [b=45.3, 95% confidence interval (CI): 13.5-77.1, P=0.006], suggesting concomitant up-regulation of neutrophil activation and apoptosis. A combined group showed significantly decreased calprotectin concentrations in cesarean sections [b=-74.5, 95% CI: -115.2-(-33.9), P<0.001], pointing to excessive inflammatory response in vaginal deliveries. Finally, birth weight, customized centile, gender, maternal age and parity do not impact on cord blood calprotectin concentrations. CONCLUSIONS Cord blood calprotectin concentrations at term are independent of intrauterine growth, gender, parity and maternal age and probably do not reflect the increased neutrophil activation and excessive apoptosis expected in IUGR.

Abstract
OBJECTIVE It was the aim of this study to investigate circulating levels of beta(2)-microglobulin (a marker of renal function) in mothers and fetuses/neonates from intrauterine growth-restricted (IUGR, characterized by impaired nephrogenesis) and appropriate for gestational age (AGA) pregnancies. METHODS Serum beta(2)-microglobulin levels were determined in 40 parturients and their 20 IUGR and 20 AGA fetuses/neonates on postnatal days 1 (N1) and 4 (N4). Comparatively, creatinine concentrations were measured. RESULTS No significant differences in beta(2)-microglobulin levels were observed between the 2 groups. In both groups, maternal serum beta(2)-microglobulin levels were significantly lower than fetal, N1 and N4 levels (in all cases p < 0.001 in the AGA group and p <or= 0.002 in the IUGR group). In the AGA and IUGR groups, N4 beta(2)-microglobulin levels were significantly elevated compared with fetal (p = 0.004 and p = 0.001, respectively) and N1 levels (p = 0.002 and p = 0.001, respectively). In both groups, maternal and fetal beta(2)-microglobulin levels did not correlate, but beta(2)-microglobulin and creatinine levels positively correlated in maternal and neonatal samples (in all cases r >or= 0.342 and p <or= 0.031). CONCLUSIONS Serum beta(2)-microglobulin levels do not differ between IUGR and AGA groups, significantly increase after birth and are not associated with gender or gestational age. Furthermore, maternal levels do not correlate with fetal levels, implying the presence of a placental barrier.

Abstract
BACKGROUND The adipocytokine resistin inhibits adipogenesis and induces insulin resistance. Intrauterine growth-restricted (IUGR) neonates have reduced fat mass and changes of endocrine/metabolic mechanisms, predisposing to insulin resistance and metabolic syndrome in adult life. OBJECTIVES To investigate plasma resistin concentrations in maternal, fetal and neonatal samples from IUGR and appropriate-for-gestational-age (AGA) pregnancies and correlate them with respective insulin concentrations. METHODS Plasma resistin and insulin concentrations were determined in 40 mothers and their 20 IUGR and 20 AGA singleton full-term fetuses and neonates on postnatal day 1 (N1) and day 4 (N4). RESULTS No significant differences in resistin concentrations were observed between AGA and IUGR groups. In the AGA group, maternal resistin concentrations were significantly lower compared to fetal, N1 and N4 ones (p = 0.003, p = 0.017 and p = 0.039, respectively). Maternal resistin concentrations positively correlated with fetal ones (r = 0.527, p = 0.02). In the IUGR group, maternal resistin concentrations were significantly lower compared to N1 (p < 0.001) and positively correlated with N4 concentrations (r = 0.626, p = 0.007). In both groups, the effect of gender, mode of delivery, parity and adjusted birth weight (customized centiles) on resistin concentrations was not significant. No correlation between resistin and insulin concentrations was documented. CONCLUSIONS Lack of difference in resistin concentrations between IUGR and AGA groups, and lack of correlation between resistin and insulin concentrations as well as customized centiles, possibly suggests that resistin may not be directly involved in the regulation of insulin sensitivity and adipogenesis in the perinatal period. Mode of delivery and parity are not associated with circulating resistin concentrations.

Abstract
Insulin-like growth factor (IGF)-I and insulin are essential for fetal growth. We investigated perinatal changes of both factors in 40 mothers and their 20 appropriate-for-gestational-age (AGA) and 20 intrauterine-growth-restricted (IUGR) fetuses and neonates on day 1 (N1) and day 4 (N4) postpartum. Fetal and N1, but not N4, IGF-I levels were increased in AGA (P < .001 and P = .037, resp.). N1 insulin levels were lower in IUGR (P = .048). Maternal, fetal, and N1 IGF-I, and fetal insulin levels positively correlated with
customized centiles (r = .374, P = .035, r = .608, P < .001, r = .485, P = .006, and r = .654, P = .021, resp.). Female infants presented elevated fetal and N4 IGF-I levels (P = .023 and P = .016, resp.). Positive correlations of maternal, fetal, and neonatal IGF-I levels, and fetal insulin levels with customized centiles underline implication of both hormones in fetal
growth. IUGR infants present gradually increasing IGF-I levels. Higher IGF-I levels are documented in
females.
