Introduction: The aim of this study was to investigate the value of placental growth factor (PLGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and sFlt-1/PLGF ratio, in predicting symptomatic preeclampsia (PE). Methods: A prospective longitudinal study was carried out on 71 high risk preeclamptic women cohort. All of them had normal blood pressure level (≤140/90 mmHg) at the time of enrolment, 26.8 ± 1.5 weeks. Maternal blood was collected and plasma was stored in a freezer at -80 °C. PE was defined according to the National High Blood Pressure Education Program Working Group Criteria. Accuracy of angiogenic factors in predicting PE was evaluated using Receiver-operating characteristics. Results: Maternal plasma concentrations of PLGF and sFlt-1 were able to predict PE (0.90, p < 001; 0.78, p = 0.003, area under the curve, respectively) but the sFlt-1/PLGF ratio presented the best prediction potential over the others (0.95, area under the curve, p < 0.001). Conclusion: All angiogenesis factors were effective biomarkers in predicting PE during the second trimester, before the clinical onset of PE. [ABSTRACT FROM AUTHOR]

Methods: A prospective longitudinal study was carried out on 71 high risk preeclamptic women cohort. All of them had normal blood pressure level (≤140/90 mmHg) at the time of enrolment, 26.8 ± 1.5 weeks. Maternal blood was collected and plasma was stored in a freezer at −80 °C. PE was defined according to the National High Blood Pressure Education Program Working Group Criteria. Accuracy of angiogenic factors in predicting PE was evaluated using Receiver-operating characteristics. Results: Maternal plasma concentrations of PLGF and sFlt-1 were able to predict PE (0.90, p < 001; 0.78, p = 0.003, area under the curve, respectively) but the sFlt-1/PLGF ratio presented the best prediction potential over the others (0.95, area under the curve, p < 0.001).

Objective. To study the occurrence of congenital cardiopathies at echocardiography (CCE) in fetuses whose mothers had preexisting diabetes mellitus (PGDM) and to study the potential of using fructosamine level as a late marker (beyond the first trimester) for CCE. Methods. A register study covering 91 pregnant women that underwent routine fetal echocardiography ordered due to PGDM. The first dosage of plasma fructosamine found in 65 medical records was analyzed during prenatal care (20.4 ±± 8.0 weeks of gestation). The presence or absence of structural or functional CCE was associated with fructosamine levels by logistic regression. We assessed the effect modification odds ratio by maternal age and insulin usage. Results. Thirty-four fetuses (52.3%% of 65 fetuses) presented CCE. Twenty of them had functional CCE and 14 presented structural CCE. The mean maternal plasma fructosamine level was higher among pregnant women whose fetuses presented CCE than in those whose fetuses did not (2.86 ±± 0.73 mmol/l, 2.22 ±± 0.54 mmol/l, respectively, p < 0.0001). Crude OR for CCE and abnormal plasma fructosamine (>2.68 mmol/l) was 9.6 (2.8--33.7, 95%% CI, p < 0.0001). Adjusted OR by maternal age and insulin usage was 10.9 (2.7--45.2, 95%% CI p < 0.0001). Conclusions. An abnormal plasma fructosamine level increases the chances of CCE occurring among referral pregnant women with PGDM. [ABSTRACT FROM AUTHOR]
