Objective Sleep disturbances and alterations of diurnal endocrine rhythms are associated with increased risk of type 2 diabetes (T2D). We previously showed that young men born small for gestational age (SGA) and with increased risk of T2D have elevated fat and decreased glucose oxidation rates during nighttime. In this study, we investigated whether SGA men have an altered diurnal profile of hormones, substrates and inflammatory markers implicated in T2D pathophysiology compared with matched individuals born appropriate for gestational age (AGA). Methods We collected hourly blood samples for 24 h, to measure levels of glucose, free fatty acids (FFA), triglycerides (TG), insulin, C-peptide, leptin, resistin, ghrelin, plasminogen activator inhibitor-1 (PAI-1), incretins (GLP-1 and GIP), and inflammatory markers (TNF-α and IL-6) in 13 young men born SGA and 11 young men born AGA. Results Repeated measurements analyses were used to analyze the diurnal variations and differences between groups. The SGA subjects had increased 24-h glucose (P=0.03), glucagon (P=0.03) and resistin (P=0.003) levels with no difference in diurnal rhythms compared with AGA controls. We found significant diurnal variations in levels of blood glucose, plasma TG, FFA, insulin, C-peptide, GLP-1, GIP, leptin, visfatin, TNF-α, IL-6 and PAI-1. The variation in FFA levels differed between the groups during the evening. Plasma ghrelin and glucagon levels did not display diurnal variations. Conclusions Young men born SGA exhibit elevated 24-h blood glucose, and plasma glucagon and resistin levels with no major differences in diurnal rhythms of these or other key metabolic hormones, substrates or inflammatory markers implicated in the origin of adiposity and T2D.

Background. Large for gestational age (LGA) infants are more prone to be obese and are at a higher risk of metabolic complications later in life. It is established that Asians have lower skeletal muscle mass and excess body fat for a given body mass index. Thus, objective of this study was to determine the relationship between leptin, insulin, C-peptide in cord blood on the birth weight of newborns and to determine whether these parameters are deviated from data already published from other populations. Methods. Umbilical cord blood was collected from 90 newborns (male 50, gestational age 38–42 weeks) which comprise of 43 LGA and 47 appropriate for gestational age (AGA) newborns. Serum leptin, insulin and C-peptide levels were measured and anthropometric parameters of the newborn and maternal characteristics were recorded. Results. Significantly higher (P<0.001) concentrations of leptin, insulin and C-peptide levels (12.670 ± 2.345 ng/mL, 18.725 ± 0.644 µIU/mL, 9.318 ± 0.772 ng/mL) were observed in the LGA group compared to AGA group (7.108 ± 0.906 ng/mL, 13.081 ± 0.428 µIU/mL, 5.439 ± 0.192 ng/mL) and all three parameters showed positive and significant correlations with anthropometric parameters of the newborn and maternal characteristics. Conclusion. Although increased leptin, insulin and C-peptide levels may be involved in insulin resistance, increased adiposity and macrosomia, they were not significantly deviated from published data from other populations. Other factors may contribute to higher fat mass found in Asian populations and finding this relationship during neonatal period is useful to predict risk factors for childhood obesity.

AbstractObjectivesTo evaluate the serum levels of the serine proteinase inhibitor kallistatin in women with preeclampsia (PE).MethodsThe clinical and laboratory parameters of 55 consecutive women with early-onset PE (EOPE) and 55 consecutive women with late-onset PE (LOPE) were compared with 110 consecutive gestational age (GA)-matched (±1 week) pregnant women with an uncomplicated pregnancy and an appropriate for gestational age fetus.ResultsMean serum kallistatin was significantly lower in women with PE compared to the GA-matched-controls (27.74±8.29 ng/mL vs. 37.86±20.64 ng/mL, p<0.001); in women with EOPE compared to that of women in the control group GA-matched for EOPE (24.85±6.65 ng/mL vs. 33.37±17.46 ng/mL, p=0.002); and in women with LOPE compared to that of women in the control group GA-matched for LOPE (30.87±8.81 ng/mL vs. 42.25±22.67 ng/mL, p=0.002). Mean serum kallistatin was significantly lower in women with EOPE compared to LOPE (24.85±6.65 ng/mL vs. 30.87±8.81 ng/mL, p<0.001). Serum kallistatin had negative correlations with systolic and diastolic blood pressure, creatinine, and positive correlation with GA at sampling and GA at birth.ConclusionsSerum kallistatin levels are decreased in preeclamptic pregnancies compared to the GA-matched-controls. This decrease was also significant in women with EOPE compared to LOPE. Serum kallistatin had negative correlation with systolic and diastolic blood pressure, creatinine and positive correlation with GA at sampling and GA at birth.

The infant who is small for gestational age (SGA) is more mature at birth than similar weight infants who are appropriate for gestational age (AGA). Whether the SGA infant behaves as does the larger gestationally equivalent infant, or whether there are specific changes related to intrauterine growth retardation is a matter of some interest in the understanding of the special needs of these infants. The National Institute of Child Health and Human Development (NICHD) phototherapy study provided a large newborn population for whom birth weight, gestational age at birth, and, thereby, intrauterine growth were carefully assessed. Infants who weighed 2,000 g or more at birth were included in the study only when they became jaundiced, whereas infants who weighed less than 2,000 g at birth were routinely entered into the study. Consequently, this report will be limited to the lowbirth-weight population selected by birth weight. Too few SGA babies were present in the groups with greater birth weight to allow meaningful comparisons. PATIENT SELECTIQN All infants whose birth weight was less than 2,000 g were entered into the study at 24 ± 12 hours. Those excluded from the study were: (1) infants who died before 24 hours, (2) infants with serious congenital defects, and (3) infants whose mothers refused consent for study. The study population consisted of 922 infants surviving at 24 hours. Gestational age was calculated from the first day of the last menstrual period obtained from maternal history and also by the evaluation techniques of Dubowitz.25 Intrauterine growth was determined by plotting birth weight and gestational age on the Denver Intrauterine Growth Curves8; infants below the 10th percentile were considered SGA.

Serum Gh

Recent investigations have raised the possibility that growth hormone (GH) influences intra-uterine weight and length. Moreover, the hypoglycemic tendency of small for gestational age (FSGA) infants and their small size could result from GH deficiency. To verify these hypotheses, a prospective study of daily serum GH and glucose levels was conducted in 46 newborn infants, including 18 FSCA infants, 18-full-term, appropriate for gestational age (FAGA), and 10 premature (PR) infants. Two FSGA babies became hypoglycemic. Both manifested normal GH competence as evidenced by normal daily GH levels, adequate GH response to arginine provocation, and satisfactory growth for over 2 years. Eleven of 12 FSGA babies followed from 14 to 26 months showed no evidence of impaired linear growth. The FSGA babies had GH values similar in magnitude and pattern to those of FAGA and PR infants. During the second half of the first postnatal day, a significant rise in serum GH occurred in all infants regardless of their size or gestational age; this rise may be the result of the stimulating effect of early milk feedings. GH deficiency does not appear to contribute to either the small size or hypoglycemic tendency of FSGA newborn infants.
