Introduction: Preeclampsia (PE) is a major pregnancy complication, posing considerable morbidity and mortality. The maternal serum angiogenic factors - PlGF and sFlt-1, and their ratio appear to be promising markers to predict PE. Aims: To assess whether the evaluation of PlGF and sFlt-1 adds to the clinical workup of women with suspected PE, and to estimate the cost/benefit., Methods: We prospectively enrolled pregnant women with suspected PE who were admitted to the Maternal-Fetal Medicine Unit (MFM) at Shamir Medical Center. Pregnancy and delivery records were collected from their computerized electronic medical records. PlGF<150pg/ml and sFlt-1/PlGF>38 measured prospectively were used to predict PE., Results: Of 105 women included, 28 were in the control group with unrelated complications and none developed PE. Among 66 women with suspected PE, 27(41%) developed the syndrome, with a positive predictive value (PPV) of 90.3% for PlGF<150 pg/ml and 88.9% for sFlt-1/PlGFabove 38. Out of 11 women with suspected intrauterine growth restriction (IUGR), six developed the syndrome, and among them, the negative predictive value (NPV) was ~ 90%., Conclusions: Angiogenic factors are reliable in predicting PE near delivery. Of 8355 annual deliveries, 584 were admitted for suspected PE. The annual test cost was NIS 66,576 (NIS 140 per single test). Cost-saving was NIS 2.18 million, the ratio of cost saved vs. test cost was 32.7., Discussion: The angiogenic factors are efficient and cost-saving in PE prediction near delivery. A larger study is necessary to determine the inclusion of angiogenic factors in the workup for suspected PE.

Introduction: Preeclampsia (PE) is a major obstetric complication affecting 3-5% of pregnancies and a major contributor to fetal and maternal morbidity and mortality. The level of placental growth factor (PLGF) >150pg/ml in the third trimester was reported to predict PE occurrence within the next 14 days., Aims: We have conducted a preliminary study among pregnant Israeli women in order to evaluate whether maternal serum PLGF test at admission with suspected PE could rule-out the risk for developing PE., Methods: We prospectively enrolled pregnant women who were admitted to the high-risk pregnancy department at Shamir Medical Center with suspected PE. The women signed an informed consent form and blood samples were drawn, separated into serum, and taken for PLGF immuno-diagnostic test. All women with suspected PE were managed according to local protocol. The medical staff was blinded regarding PLGF results. All patients' computerized medical records, including developing of PE within 14 days and patients' computerized medical records were collected and a telephone interview was held to verify whether post charging events occurred., Results: Of the 29 women who were enrolled in the study, the group with PLGF<150 pg/ml included 19 women, who had mean PLGF=44.7pg/ml [(95%CI: 6.5-95.3], of which 14 developed PE (positive predictive value 73.7%). There were ten women in the PLGF>150pg/ml group, with mean PLGF=528.7 pg/ml [(95% CI:168-1300, P<0.001)] of which one developed PE (negative predictive value 90%). The sensitivity for ruling out PE by PLGF>150pg/ml was 93%, and the specificity=64.3., Conclusions: Incorporating blood testing of PLGF into the evaluation triage of pregnant women in Israel who admitted to the delivery clinic with suspected development of PE has generated high efficacy and negative predictive value (NPV) as was previously published Our findings are in accordance with results reported elsewhere but need validation in Israel with larger studies., Discussion: Assuming that at least 7% of ~184,450 (2018) live births in Israel are admitted to the high risk departments for evaluating suspected PE, implementing a PLGF test has a cost-benefit ratio of ~1/8.28 with a cost of NIS 2.52M for test performance of all women attending the delivery clinic with suspected PE over saving NIS 21.37M on unnecessary hospital days.
