[PMID: 37764842 PMCID: PMC10535905 DOI: 10.3390/nu15184059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/11/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
An important role in the network of interconnections between the mother and child is played by adipokines, which are adipose tissue hormones engaged in the regulation of metabolism. Alternations of maternal adipokines translate to the worsening of maternal insulin resistance as well as metabolic stress, altered placenta functions, and fetal development, which finally contribute to long-term metabolic unfavorable conditions. This paper is the first to summarize the current state of knowledge concerning the concentrations of individual adipokines in different biological fluids of maternal and cord plasma, newborn/infant plasma, milk, and the placenta, where it highlights the impact of adverse perinatal risk factors, including gestational diabetes mellitus, preeclampsia, intrauterine growth restriction, preterm delivery, and maternal obesity on the adipokine patterns in maternal-infant dyads. The importance of adipokine measurement and relationships in biological fluids during pregnancy and lactation is crucial for public health in the area of prevention of most diet-related metabolic diseases. The review highlights the huge knowledge gap in the field of hormones participating in the energy homeostasis and metabolic pathways during perinatal and postnatal periods in the mother-child dyad. An in-depth characterization is needed to confirm if the adverse outcomes of early developmental programming might be modulated via maternal lifestyle intervention.

Abstract
The factors controlling linear growth and weight gain in the human fetus and newborn infant are poorly understood. We review here the changes in linear growth, weight gain, lean body mass, and fat mass during mid- and late gestation and the early postnatal period in the context of changes in the secretion and action of maternal, placental, fetal, and neonatal hormones, growth factors, and adipocytokines. We assess the effects of hormonal determinants on placental nutrient delivery and the impact of preterm delivery on hormone expression and postnatal growth and metabolic function. We then discuss the effects of various maternal disorders and nutritional and pharmacologic interventions on fetal and perinatal hormone and growth factor production, growth, and fat deposition and consider important unresolved questions in the field.

Front Endocrinol (Lausanne) 2021; 12:738964. [PMID: 34659122 PMCID: PMC8515017 DOI: 10.3389/fendo.2021.738964] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 08/26/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Premature/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. METHODS A 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. RESULTS The 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). CONCLUSIONS The 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.

Modifications of Own Mothers' Milk Fortification Protocol Affect Early Plasma IGF-I and Ghrelin Levels in Preterm Infants. A Randomized Clinical Trial. Nutrients 2019; 11:nu11123056. [PMID: 31847328 PMCID: PMC6950485 DOI: 10.3390/nu11123056] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 12/03/2019] [Accepted: 12/11/2019] [Indexed: 12/19/2022] Open
Abstract
The aim was to investigate the effect of two own mother’s milk (OMM) fortification protocols on (a) IGF-I and ghrelin plasma levels at 35 post-conceptional weeks (PCW, T2) and whether this effect is maintained after elimination of the differences in OMM fortification, and (b) growth until 12 months corrected age. Forty-eight OMM-fed preterm infants (GA 24–32 weeks) were randomly allocated to the fixed-fortification (FF) group (n = 23) and the protein-targeting fortification (PTF) group (n = 25) targeting the recommended daily protein intake (PI). Plasma IGF-I and ghrelin were assessed at 35 (T2) and 40 (T3) PCW while growth was longitudinally assessed until 12 months corrected age. PTF group had lower IGF-I and higher ghrelin than FF group at T2, while receiving lower daily protein and energy amounts. PI correlated positively to T2-IGF-I and inversely to T3-ghrelin while energy intake (EI) correlated inversely to T2- and T3-ghrelin. Group and PI were independent predictors of adjusted T2-IGF-I, while group and EI were predictors of adjusted and T2-ghrelin. Growth parameter z-scores were comparable between groups up to 12 months corrected age. Modifications of OMM fortification have a transient effect on early plasma IGF-I and ghrelin levels in preterm infants in a way consistent with the previously recognized protein-energy/endocrine balance, indicating a potential programming effect.

Abstract
PURPOSE Ghrelin is a potent orexigenic peptide hormone secreted from the gastrointestinal tract that plays a crucial role in the regulation of lipids and glucose metabolism. Ghrelin also has links with fetal development and growth. Gestational diabetes mellitus (GDM) causes fetal macrosomia, but there is no available evidence of a relationship between ghrelin levels and birth weight in women with GDM. The purpose of this study is to investigate whether umbilical cord ghrelin concentrations are altered in full-term pregnant women with GDM compared to women without GDM and whether birth weight is correlated with ghrelin levels. MATERIALS AND METHODS Sixty pregnant women with GDM and 64 healthy pregnant women without GDM were included in this cross-sectional study. Blood samples were drawn from the umbilical vein following birth. Ghrelin concentrations were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS Umbilical vein ghrelin levels were decreased in women with GDM (879.6 ± 256.1 vs. 972.2 ± 233.6 pg/ml in women without GDM, p=0.033), whereas birth weights were higher for babies in the GDM than in the non-GDM group (3448 ± 410 vs. 3308 ± 365 gr, respectively, p=0.046). Umbilical ghrelin levels were inversely correlated with birth weight (r=-0.765, p<0.001). Multiple regression analysis revealed that birth weight was independently and negatively associated with umbilical ghrelin levels (β= -2.077, 95% CI=-2.652 to -1.492, p=0.002). CONCLUSIONS Umbilical ghrelin levels were lower in GDM women. Birth weight was inversely associated with umbilical ghrelin levels. This association may be explained by a negative feedback mechanism between ghrelin and birth weight.

Abstract
Although ghrelin in cord blood has been associated to birth weight, its role in fetal and postnatal growth has not been elucidated. The aim of this study was to analyze total ghrelin, acyl ghrelin (AG), and des-acyl ghrelin (DAG) in cord blood of newborns with idiopathic birth weight alterations, and to evaluate protein expression of placental GHS-R1, in order to investigate their correlation with birth weight and placental weight. We performed a cross-sectional comparative study in umbilical cord blood and placentas from healthy mothers of SGA, AGA, and LGA (small, adequate and large for gestational age) term newborns (n = 20 per group). Cord blood total ghrelin, AG, and DAG were measured by ELISA, and placental GHS-R1 expression was evaluated by Western blot. Cord blood DAG was higher in SGA compared to AGA newborns (902.1 ± 109.1 and 597.4 ± 58.2 pg/ml, respectively, p = 0.01) while LGA and AGA showed similar values (627.2 ± 76.4 pg/ml for LGA, p = 0.80). DAG negatively correlated with birthweight (r = -0.31, p = 0.02) and placental weight (r = -0.33, p = 0.02). No differences in AG or total ghrelin were found. GHS-R1 protein in placenta was not differentially expressed among SGA, AGA, and LGA. Our results suggest a role of DAG in intrauterine growth. Further studies are needed in order to elucidate the mechanisms by which DAG participates in fetal growth.

Abstract
OBJECTIVE To investigate relationship between anthropometric values of premature babies with their's glucose, insulin, leptin, and ghrelin at birth and on day 15. METHODS We analyzed fasting and postprandial glucose, insulin, leptin, and ghrelin levels at birth and on day 15 in babies born prematurely between 24 and 37 weeks, and who did not have serious problems aside from prematurity at birth. RESULTS Fasting glucose, insulin, leptin and ghrelin values of babies at birth and on day 15 were significantly lower than postprandial values (all p values p < 0.001). There were positive correlations between the mean insulin, leptin, and ghrelin levels with the gestational age, birth weight, body mass index, head circumference of babies at birth, and anthropometric values on day 15 (all r values > 0.400, all p values < 0.05). Fasting glucose, leptin, and ghrelin values of mothers birth were significantly lower than post-prandial values (all p values p < 0.05). CONCLUSIONS The positive correlations between the insulin, leptin, and ghrelin values of babies at birth with gestational age and anthropometric values suggest that both hormones play important roles in fetal and neonatal growth and development.

Abstract
OBJECTIVE We examined the association of active ghrelin levels with birth weight, sex, and gestational age (GA) in small for GA (SGA) and appropriate for GA (AGA) preterm infants. METHODS Active ghrelin levels were measured by ELISA method during the first five postnatal days in 38 preterm SGA infants and 32 preterm AGA controls. RESULTS Active ghrelin levels were significantly higher in preterm SGA infants than in preterm AGA controls (P < 0.01). Active ghrelin levels in preterms with birth weight <1500 g were statistically higher than those over 1500 g. Active ghrelin levels in preterms ≤ 34 gestational weeks were similar to those over 34 weeks. A negative correlation was detected between active ghrelin levels and birth weight (r = -0.561, P < 0.0001) as well as GA (r = -0.449, P < 0.0001). CONCLUSION We found significantly higher active ghrelin levels in SGA preterms than those in AGA preterms and demonstrated a negative correlation between active ghrelin levels and birth weight in preterm infants. This was the first study showing a negative correlation between active ghrelin levels and birth weight in preterm infants.

Abstract
AIM We investigated the relationship between plasma insulin-like growth factor I (IGF-I), leptin, active ghrelin levels, and postnatal growth in very low birth weight (VLBW) infants. METHOD Plasma IGF-I, leptin, and active ghrelin levels were measured at birth and at 2, 4, 6 and 8 weeks after birth in 61 VLBW infants, including 31 appropriate-for-gestational-age (AGA) and 30 small-for-gestational-age (SGA) infants. RESULTS Insulin-like growth factor I levels were the lowest at birth, but increased gradually over the first 8 weeks of life. IGF-I was positively correlated with body weight, body length and body mass index at all time points. Leptin levels did not change over the study period. Ghrelin levels were significantly lower at birth; however, there were no significant differences between the levels after 2 weeks of age. Leptin and ghrelin levels were not correlated with anthropometrical measures. IGF-I levels at birth were significantly lower in SGA than in AGA infants, but the leptin and ghrelin levels were not significantly different between the two groups. CONCLUSION Insulin-like growth factor I is related to length and weight gain in the prenatal and the early postnatal periods in VLBW infants, but this does not appear to be the case for leptin and ghrelin.

Abstract
OBJECTIVE To determine the influence of gestational age and fetal growth restriction on the cord blood adipokine profile, IGF1, and ghrelin levels, and their relationship with glucose metabolism. STUDY DESIGN One hundred and ninety newborns (99 preterm and 91 full term) were studied and, according to their anthropometry at birth, classified as small (SGA) or adequate for gestational age (AGA). METHODS Venous cord blood serum levels of IGF1, IGF binding protein 3 (IGFBP-3), adiponectin, resistin, leptin, soluble leptin receptor (sOB-R), tumoral necrosis factor-alpha, interleukin 6 (IL-6), total ghrelin, and acylated ghrelin were determined and compared between preterm and full-term, as well as between SGA and AGA, newborns. Correlations with newborn weight, gestational age, and homeostatic model assessment (HOMA) index, as an index of insulin resistance, were determined. RESULTS Preterm newborns had higher HOMA, sOB-R, resistin, and IL-6 and lower IGF1, IGFBP-3, leptin, and adiponectin levels than full-term newborns. SGA had lower IGF1, IGFBP-3, leptin, IL-6, and adiponectin and higher sOB-R and total ghrelin than AGA newborns. Adiponectin and HOMA showed independent positive and negative correlations with gestational age respectively, but not with neonatal weight. Birth weight was correlated positively with IGF1 and leptin levels and negatively with total ghrelin ones. CONCLUSIONS Our findings suggest that the lack of proper acquisition of adipose tissue by the fetus either due to prematurity or to fetal growth restriction is associated with changes in the cord blood adipokine profile that may contribute to the impairment of glucose metabolism.
