ABSTRACT The objectives of the present study were to determine whether or not increased serum ferritin in women with premature labour is associated with gestational diabetes mellitus (GDM) and intra-uterine growth retardation (IUGR) and, if so, whether or not such increased levels reflect excess maternal iron stores, and have an effect on neonatal iron status and outcome.
This prospective, single-hospital, observational study involved 63 mothers and their 90 preterm neonates. Full blood counts as well as serum ferritin, soluble transferrin receptor (sTfR) and erythropoietin concentrations were compared across the three study groups based on maternal ferritin levels at the time of delivery. Perinatal history, neonatal morbidity and early outcomes were also assessed.
High maternal ferritin levels were significantly associated with higher rates of GDM and IUGR. However, there was no correlation between maternal ferritin and sTfR levels or between maternal and neonatal iron status.
Elevated maternal ferritin is not a reflection of excess iron stores, but is related to an increased risk of GDM or IUGR. Also, maternal ferritin levels are not associated with either neonatal iron status or neonatal outcomes.

    ABSTRACT: Normal human pregnancy is considered a state of enhanced oxidative stress. In pregnancy, it plays important roles in embryo development, implantation, placental development and function, fetal development, and labor. However, pathologic pregnancies, including gestational diabetes mellitus (GDM), are associated with a heightened level of oxidative stress, owing to both overproduction of free radicals and/or a defect in the antioxidant defenses. This has important implications on the mother, placental function, and fetal well-being. Animal models of diabetes have confirmed the important role of oxidative stress in the etiology of congenital malformations; the relative immaturity of the antioxidant system facilitates the exposure of embryos and fetuses to the damaging effects of oxidative stress. Of note, there are only a few clinical studies evaluating the potential beneficial effects of antioxidants in GDM. Thus, whether or not increased antioxidant intake can reduce the complications of GDM in both mother and fetus needs to be explored. This review provides an overview and updated data on our current understanding of the complications associated with oxidative changes in GDM.

    ABSTRACT: Foetal growth is a result of a complex net of processes, requiring coordination within the maternal, placental, and foetal compartments, the imbalance or lack of which may lead to intrauterine growth restriction (IUGR). IUGR is the major cause of perinatal morbidity and mortality, and is also related to enhanced morbidity and metabolic abnormalities later in life. In the present study, the protein profiles of umbilical cord serum (UCS) and amniotic fluid (AF) of ten IUGR and ten appropriate for gestational age newborns have been analysed by 2-DE, and nanoHPLC-Chip/MS technology. A total of 18 and 13 spots were found to be differentially expressed (p<0.01) in UCS and AF respectively. The unique differentially expressed proteins identified by MS/MS analysis were 14 in UCS, and 11 in AF samples. Protein gene ontology classification indicate that 21% of proteins are involved in inflammatory response, 20% in immune response, while a smaller proportion are related to transport, blood pressure, and coagulation. These results support the conclusion that the IUGR condition alters the expression of proteins involved in the coagulation process, immune mechanisms, blood pressure and iron and copper homeostasis control, offering a new insight into IUGR pathogenesis.

    ABSTRACT: Objective: To examine the potential value of maternal serum level of ferritin in the first trimester of pregnancy in the prediction of spontaneous early preterm delivery. Methods: Maternal serum concentration of ferritin at 11-13-week gestation was measured in a case-control study of singleton pregnancies delivering phenotypically normal neonates, including 30 cases with spontaneous delivery before 34 weeks and 90 matched controls delivering after 37 weeks. The median multiple of the median (MoM) serum ferritin in the two outcome groups was compared. Results: The median serum ferritin MoM was not significantly different in the spontaneous early preterm delivery group compared with the term delivery group (1.143, interquartile range [IQR] 0.578-2.383 vs. 1.059, IQR 0.641-1.644, p = 0.725). Conclusions: Measurement of maternal serum ferritin at 11-13 weeks is unlikely to be useful in screening for spontaneous early preterm delivery.
