Objective: Preeclampsia is a common disorder of pregnancy, causing significant morbidity and mortality for mothers and infants. Several molecules, including glycosylated fibronectin (GlyFn), the inhibin-related proteins, anti-müllerian hormone (AMH), and the insulin-like growth factor axis, are altered in maternal plasma in the setting of preeclampsia; however, these molecules have not been previously measured in cord blood of infants born to mothers with preeclampsia, which may represent changes in fetal physiology. We evaluated potential biomarkers of preeclampsia in umbilical cord blood to fill the gap in knowledge. Methods: This is a case-control study of 196 neonates born at a tertiary teaching hospital in Boston from 2010–2017. Forty-nine neonates born to mothers with preeclampsia were matched 1:3 by gestational age, sex, and birth weight z-score with 147 controls. Eleven analytes were measured in cord blood by enzyme-linked immunosorbent assay. Binary logistic regression analyses were performed to evaluate associations between preeclampsia and analytes. Results: Mean cord blood levels of GlyFn and total inhibin were significantly lower in neonates born to mothers with preeclampsia compared to controls, and AMH levels were significantly higher in males born to mothers with preeclampsia than male controls. Associations remained significant after controlling for maternal and neonatal characteristics. Conclusion: Cord blood levels of GlyFn and inhibin are decreased and AMH (male) levels are increased in infants of preeclamptic mothers, which is opposite the pattern these biomarkers show in serum of mothers with preeclampsia. These molecules may be important in the pathophysiology and long-term effects of preeclampsia on the developing fetus. Abbreviations: AMH = anti-müllerian hormone; ELISA = enzyme-linked immunosorbent assay; GlyFn = glycosylated fibronectin; IGF = insulin-like growth factor; IGFBP5 = insulin-like growth factor binding protein 5; LOD = limit of detection; PAPP-A = pregnancy-associated plasma protein A; PAPP-A2 = pregnancy-associated plasma protein A2

ObjectiveTo assess ampicillin levels according to the duration of intrapartum antibiotic prophylaxis (IAP).DesignProspective cohort single-centre study.SettingTertiary care centre (Modena, Italy).Patients120 neonates≥35 weeks’ gestation exposed to IAP.InterventionsNeonates were divided into four groups, according to the duration of IAP prior to delivery: group 1 (n=30; <1 hour), group 2 (n=30; ≥1 and <2 hours), group 3 (n=30; ≥2 and <4 hours) and group 4 (n=30; ≥2 doses, ≥4 hours).Main outcome measuresBlood samples were collected at delivery (from the umbilical cord) and at age 4 hours (from a peripheral vessel).ResultsMedian duration of IAP was 121 min (range 7–2045 min). Median ampicillin levels in umbilical cord blood were 10.4 µg/mL (IQR 6.4–14.9) and in peripheral blood were 4.7 µg/mL (IQR 2.8–6.4µg/mL). Umbilical cord blood levels reached a peak approximately 30 min after IAP and then declined significantly (p<0.001). Peripheral blood levels did not differ among study groups. Neonates exposed to a full loading dose (n=115) had peripheral blood levels 2.5–70 times higher than the minimal inhibitory concentration for group B streptococcus. There was no relationship between neonatal ampicillin concentrations and the duration of IAP prior to delivery (β=−0.0003, 95% CI −0.02 to 0.001, p=0.680).ConclusionsAmpicillin levels reach a peak in the umbilical cord blood within 30 min of intrapartum administration. After a full loading dose, bactericidal levels persist for at least 4 hours after birth and seem independent of the duration of IAP prior to delivery.
