Iugr aging placenta diabetes

The offspring of mothers with gestational diabetes mellitus GDM and those with intrauterine growth restriction IUGR are at increased risk for developing obesity and metabolic syndrome MetS in later life 7 , 8. The most widely accepted explanation for long-term consequences is fetal programming of hypothalamic systems involved in neurohormonal regulation of metabolism and appetite, which are highly vulnerable to metabolic insults during the perinatal period.

Experimental studies showed that under- or overnutrition during fetal and early postnatal periods is associated with permanent alterations of the hypothalamic neurons expressing the appetite-regulating neuropeptides 9 , Experimental models of GDM and IUGR demonstrated increased hypothalamic galanin mRNA expression and galanin neurons in the offspring associated with permanent malformations of hypothalamic nuclei in adult life 10 — However, hypothalamic galanin expression cannot be assessed in humans.

We hypothesized that plasma galanin at birth would reflect presumably altered hypothalamic galanin production. Therefore, it could be a useful indicator for the need of early intervention to prevent obesity and MetS in neonates at risk. In this context, we investigated whether neonates born to GDM mothers or being IUGR differ from healthy ones in circulating galanin at birth. The control group consisted of 25 healthy neonates matched for gestational age, born to mothers with normal fasting glucose and oral glucose tolerance test.

Exclusion criteria included intrauterine infection, congenital anomalies, coexistence of GDM with IUGR, and refusal of parental consent. The 2-h oral glucose tolerance test using a loading dose of 75 g glucose was performed between the 24th and 28th week of gestation. The glucose threshold values for the diagnosis of GDM were 0. The level of diabetic control was assessed with serum glycosylated hemoglobin HbA1c during pregnancy based on clinical judgment. Additionally, HbA1c was measured before delivery in all mothers enrolled in the study.

In 13 GDM mothers, glucose control was managed with diet, whereas 12 required insulin. Anthropometric measurements included maternal weight before gestation and at delivery, weight gain during pregnancy, height, and body mass index BMI as well as neonatal birth weight, length, and BMI. The study was approved by the Scientific Committee of our institution, and informed consent was obtained from all parents. Blood sample handling and peptide assay Venous blood samples 1 ml were collected from all neonates within 1 h after birth in prechilled EDTA tubes containing aprotinin Sigma-Aldrich Corp.

Louis, MO and were immediately centrifuged. Plasma galanin was assayed using the galanin human enzyme immunoassay kit, extraction free Peninsula Laboratories, San Carlos, CA. All measurements were performed in duplicate, and the mean of the two measurements was considered. Medical conditions such as diabetes , pre-eclampsia and blood clotting conditions also increase your risk. What are the symptoms of placental insufficiency? Placental insufficiency has no symptoms.

Other signs the baby may not be developing properly are that your abdomen is smaller than in previous pregnancies. The condition may be picked up during your routine antenatal tests , which measure the growth of your uterus and the baby. How is placental insufficiency treated?

If your doctor suspects placental insufficiency, they will keep a close eye on your baby's growth. You will be asked to keep a record of the baby's movements and let your medical team know if you notice any changes. Treatment will depend on the stage of the pregnancy.

But if you are full term or there are signs that your baby is under stress, they may decide to induce labour or deliver the baby with a caesarean.

Intrauterine growth retardation IUGR , which is defined as less than 10 percent of predicted fetal weight for gestational age, may result in significant fetal morbidity and mortality if not properly diagnosed. The condition is most commonly caused by inadequate maternal-fetal circulation, with a resultant decrease in fetal growth.

Less common causes include intrauterine infections such as cytomegalovirus and rubella, and congenital anomalies such as trisomy 21 and trisomy When IUGR is recognized, it is important to attempt to correct reversible causes, although many of the conditions responsible for IUGR are not amenable to antenatal therapy. Close fetal surveillance with delivery before 38 weeks of gestation is usually recommended.

Some infants born with IUGR have cognitive and medical problems, although for most infants the long-term prognosis is good. References in the medical literature to underweight infants date back to , when it was suggested 1 that all newborns weighing less than 2, g 5 lb, 8 oz should be classified as premature.

However, it was not until that the World Health Organization WHO acknowledged that many infants defined as premature were not born early but were simply of low birth weight.

Med Hypotheses. Roberts D, Dalziel S. Antenatal corticosteroids for accelerating fetal lung maturation for women at risk of preterm birth. These have been well-characterised in the PR rat, where impaired insulin secretion is linked to epigenetic changes at the Pdx-1 promotor and reduced expression of this transcription factor. Present research is particularly focussed on developing intervention strategies to prevent or reverse epigenetic changes, and normalise gene expression and insulin action after PR, in order to translate this to treatments to improve outcomes in human IUGR.

Introduction Poor growth before birth is consistently associated with increased risks of type 2 diabetes mellitus T2D in humans, and the underlying changes in insulin sensitivity and secretion that lead toT2D following IUGR are becoming better understood.

Impaired placental growth, development and function are major causes of impaired fetal growth and development and therefore of IUGR, where the growth of the fetus is restricted relative to its genetic potential. Animal studies have allowed the role of the placenta in later development of disease of progeny to be directly investigated, and here we discuss current knowledge of mechanisms and consequences of placental restriction in the sheep and rat for insulin action after birth.

Development of these animal models also allows development and testing of interventions to prevent impaired insulin action after IUGR, and we conclude with a discussion of the current research in this area. IUGR and diabetes in humans In humans, size at birth, measured as birth weight in the majority of studies, is consistently and inversely related to glucose intolerance and the prevalence of T2D [ 1 — 3 ].

These inverse relationships are usually either linear, or J-shaped, depending on the age and ethnicity of the population being studied, where high birth weight babies of pregnancies affected by gestational diabetes are also at increased risk of T2D in later life.

Although earlier studies often did not separate effects of gestational age from intrauterine growth restriction IUGR as determinants of birth weight, a more recent study has confirmed that low birth weight predicts increased risk of T2D independent of gestational age [ 4 ]. The majority of human studies are limited in the extent of fetal growth measures that are collected, and most therefore define IUGR in terms of low birth weight relative to a local reference population, usually corrected for gestational age, rather than by direct measures of slowing growth.

Nevertheless, a low birth weight SGA may reflect genetic determinants of fetal growth in the absence of growth restriction, and a baby may be growth-restricted and within the normal birth weight range. Not only is low birth weight consistently related to increased risk of T2D, but this accounts for a substantial proportion of lifetime risk.

Contemporary cohorts of low birth weight babies and children may be at even greater risk of developing later T2D, since low birth weight also increases the risk of developing obesity in an environment of high food availability [ 6 ], and obesity impairs insulin sensitivity and significantly increases the risk for developing T2D [ 7 ].

Human IUGR and determinants of insulin action The two determinants of insulin action, and thus risk of impaired glucose tolerance and T2D, are insulin sensitivity and insulin secretion.
