In recent years, a number of the studies of myokine irisin in adults and isolated in newborns have been carried out. The role of adipocytokines in the growth and development of the fetus and children has been shown.The aim of the study was to assess the levels of myokine irisin and adipocytokines in newborns small for gestational age at birth and to analyze the relationship between the parameters of the hormonal status of children and their mothers.49 newborns and their mothers were examined. Two groups were identified: group 1 (Gr1) – newborns small for gestational age (n = 24), group 2 (Gr2) – newborns appropriate for gestational age (n = 25). The levels of irisin and adipocytokines in the blood serum were determined by the enzyme immunoassay.Newborns small for gestational age had significantly lower levels of leptin and IGF-1 in the umbilical cord blood compared to children with physical development corresponding to the gestational age. There were no significant differences in the irisin content of cord blood serum in newborn Gr1 compared with Gr2. The presence of significant positive correlations between the level of irisin in the umbilical cord blood of newborns small for gestational age and the body weight at birth was established. In Gr1, a positive relationship was found between the irisin levels of mothers and newborns (r = 0.518, p = 0.028). The differences in the irisin content between the groups were established, taking into account the delivery mode (p = 0.0104).The revealed statistically significant differences in the concentrations of the analyzed metabolic markers in mother–child pairs, their relationship with clinical and anthropometric parameters substantiate the possibility of using irisin and adipocytokines as predictors in predicting the formation of metabolic disorders of infants small for gestational age.

Abstract Objective. To characterise the umbilical cord blood immune profile in preterm infants compared to term-born controls and the postnatal immune response following exposure to histologic chorioamnionitis (HCA) in preterm infants. Design. Descriptive, observational cohort study. Setting. Edinburgh, UK. Population. 118 preterm infants (mean gestational age 29+0 weeks, range 23+2 to 32+0) and 59 term-born controls. Methods. Placental histopathology was used to identify reaction patterns indicative of HCA, and a customised immunoassay of 24 inflammatory markers and trophic proteins selected to reflect the perinatal immune response was performed on umbilical cord blood in term and preterm participants and postnatal day 5 blood in the preterm group. Results. The umbilical cord blood immune profile classified gestational age category with 86% accuracy (95% CI 0.78-0.92), p-value=1.242x10-14. Pro-inflammatory proteins IL-6, MCP-1 and CRP were elevated in the cord blood of preterm infants whilst BDNF, C3, C9, IL-18, MMP-9 and RANTES were decreased, compared to infants born at term. In preterm infants, exposure to HCA was associated with elevations in 5 immune proteins on postnatal day 5 (BDNF, C3, IL-8, MIP-1β and MMP-9) when compared to preterm infants who were not exposed. Conclusion. Preterm birth is associated with a distinct immune profile in umbilical cord blood and infants exposed to HCA experience specific alterations in immune function that persist to day 5 of postnatal life.

BackgroundPremature/low-birth-weight infants are at significant risk of metabolic diseases in adulthood, which may be related to the levels of fetal adipokine. Here, we investigated the differences in the levels of umbilical cord blood adiponectin, leptin, insulin, and ghrelin in preterm and term infants and sought to elucidate the link between these hormones and fetal growth. We also evaluated the interrelationship among these metabolic hormones in both groups of newborns.MethodsA total of 149 mother–infant pairs (100 in the preterm group and 49 in the term group) were enrolled in the study. The preterm group was further subdivided according to birth weight (≤1,500, 1,501–2,000, 2,001–2,500, and >2,500 g), gestational age (<34 vs. ≥34 weeks), and appropriate for gestational age (AGA) vs. small for gestational age (SGA). The general condition of the mothers and the growth parameters of the newborns at birth were recorded.ResultsThe levels of adiponectin, leptin, and ghrelin were lower in the preterm group than those in the term group (p < 0.05). In the preterm group, the leptin levels of infants with gestational age ≥34 weeks were significantly higher than those of infants with gestational age <34 weeks (mean ln leptin = 0.63 vs. 0.36 ng/ml, p = 0.009). The levels of adiponectin were lower in the SGA group than those in the AGA group (mean ln adiponectin = 2.26 vs. 2.84 µg/ml, p = 0.001), whereas those of ghrelin displayed the opposite trend (mean ln ghrelin = 6.29 vs. 5.71 pg/ml, p < 0.001). Leptin was significantly correlated with insulin both in preterm infants with birth weight (BW) >2,000 g and in term infants. Umbilical cord blood leptin was positively correlated with the BW, birth length, and head circumference of newborns (r = 0.460, 0.311, and 0.310, respectively, all p < 0.05), whereas ghrelin was negatively correlated with the same parameters (r = −0.372, −0.415, and −0.373, respectively, all p > 0.05).ConclusionsThe lack of maturation of adipose tissue and the gastrointestinal tract by the fetus due to prematurity is associated with changes in the levels of cord blood adiponectin, leptin, and ghrelin. The dysregulation of these hormones in preterm infants may be a risk factor for fetal growth and future metabolic diseases.

Objective This study aims to evaluate the use of umbilical cord blood as an alternative to the admission complete blood count (CBC) in the well-appearing late preterm neonates admitted to the neonatal intensive care unit. Study Design Paired umbilical cord and admission blood CBC samples from well late preterm infants were compared using a two-sample t-test or analysis of variance with an unequal variance for differences in the hemoglobin, platelet counts, white blood cell, and absolute neutrophil counts. Results A total of 100 infants were enrolled in the study. The study included 46 females, 5 Asian, 9 Black, 35 Hispanic, 51 White, with a mean gestational age of 35.3 ± 1 weeks (range: 34–36.5 weeks), and a mean birth weight of 2,347 ± 491 g (range: 1,840–4,260 g). Around 80% were appropriate for gestational age, 5% were large for gestational age, and 15% were small for gestational age. The median difference between the cord and admission blood samples were hemoglobin: 1.1 g/dL, platelet: 7.50 × 103 cells/μL, white blood cell count: 2.3 × 103 cells/μL, and absolute neutrophil count: 0.6 × 103 cells/μL. Conclusion The cord and admission blood testing were not statistically or clinically different when compared. In well late preterm infants, the NICU admission blood CBC may be replaced with an umbilical cord blood CBC.

IntroductionPreterm infants are at increased risk of exposure to histologic chorioamnionitis (HCA) when compared to term-born controls, and this is associated with several neonatal morbidities involving brain, lungs and gut. Preterm infants could benefit from immunomodulatory therapies in the perinatal period, but development of rational treatment strategies requires improved characterization of the perinatal response to HCA. We had two objectives: The first, to characterize the umbilical cord blood immune profile in preterm infants compared to term-born controls; the second, to investigate the postnatal immune response in preterm infants exposed to HCA versus those who were not.PopulationFor objective one 59 term infants [mean gestational age (GA) 39+4 (37+3 to 42+0)] and 55 preterm infants [mean GA29+0(23+3 to 32+0)] with umbilical cord samples available were included; for objective two we studied 96 preterm infants [mean GA29+1(23+2 to 32+0)] for whom placental histology and postnatal blood samples were available.MethodsPlacental histopathology was used to identify reaction patterns indicative of HCA, and a customized immunoassay of 24 inflammatory markers and trophic proteins selected to reflect the perinatal immune response was performed on umbilical cord blood in term and preterm participants and postnatal day 5 blood in the preterm group.ResultsThe umbilical cord blood immune profile classified gestational age category with 86% accuracy (95% CI 0.78-0.92), p-value=1.242x10-14. Pro-inflammatory proteins IL-6, MCP-1 and CRP were elevated in the cord blood of preterm infants whilst BDNF, C3, C9, IL-18, MMP-9 and RANTES were decreased, compared to infants born at term. In preterm infants, exposure to HCA was associated with elevations in 8 immune proteins on postnatal day 5 (BDNF, C3, C5a, C9, IL-8, MCP-1, MIP-1β and MMP-9) when compared to preterm infants who were not exposed.ConclusionPreterm birth is associated with a distinct immune profile in umbilical cord blood and preterm infants exposed to HCA with evidence of a fetal inflammatory response have specific alterations in immune function that are apparent on day 5 of postnatal life.
