Abstract

Introduction

The aim of this study was to evaluate differences in circulating maternal placental biomarkers and fetoplacental Dopplers in women with diabetes mellitus in pregnancy (DIP) with prenatally identified small fetuses (defined as <20th centile for gestational age) compared to women with small fetuses without DIP.

Methods

This was a prospective cohort study of women with DIP with small infants compared to a non-diabetic cohort with similarly small fetuses. Multivariable logistic regression was used to evaluate the effect of DIP on placental biomarkers, fetoplacental Dopplers, and adverse perinatal outcomes.

Results

There were 447 pregnancies in this study – 117 (26.2 %) had DIP and 330 (73.8 %) did not have diabetes. Of the DIP cohort, 57 (48.7 %) had early-onset and 27 (23.1 %) had late-onset FGR. Higher rates of low PlGF levels<100 ng/L (42.1 % vs. 25.7 %,p = 0.002), high sFlt-1/PlGF ratio (39.6 % vs. 25.4 %,p = 0.006), low MCA PI < 5th centile at recruitment (18.8 % vs. 7.6 %,p < 0.001, OR 2.37 95%CI 1.25, 4.46,p = 0.008), abnormal UA Doppler before delivery (OR 1.63 95%CI 1.00, 2.66,p = 0.048) were seen in the DIP cohort. DIP was associated with higher rates of emergency cesarean section (43.6 % vs. 26.7 %,p = 0.001) and lower birthweight (2300 (1558, 2610g) vs. 2447 (2050, 2690g),p = 0.003). The odds of early FGR (OR 1.90 95%CI 1.20, 2.98,p = 0.006), PTB<37 weeks (OR 1.66 95%CI 1.02, 2.70,p = 0.039), PTB<34 weeks’ gestation (OR 3.00 95%CI 1.51, 5.96,p = 0.002), composite non-neurological neonatal morbidity (OR 1.86 95%CI 1.04, 3.33,p = 0.037), and hypoglycemia (OR 3.69 95%CI 1.59, 8.54,p = 0.002) were significantly higher in DIP.

Conclusions

DIP is associated with increased risks of early-onset FGR, PTB, composite severe non-neurological neonatal morbidity, and neonatal hypoglycemia in women with small infants. DIP was significantly associated with increased odds of MCA PI < 5th centile at diagnosis and abnormal UA Doppler before birth.

期刊介绍： Placenta publishes high-quality original articles and invited topical reviews on all aspects of human and animal placentation, and the interactions between the mother, the placenta and fetal development. Topics covered include evolution, development, genetics and epigenetics, stem cells, metabolism, transport, immunology, pathology, pharmacology, cell and molecular biology, and developmental programming. The Editors welcome studies on implantation and the endometrium, comparative placentation, the uterine and umbilical circulations, the relationship between fetal and placental development, clinical aspects of altered placental development or function, the placental membranes, the influence of paternal factors on placental development or function, and the assessment of biomarkers of placental disorders.
