Modeling risk for severe adverse outcomes using angiogenic factor measurements in women with suspected preterm preeclampsia
Introduction Preeclampsia (PE) is a pregnancy‐specific syndrome associated with adverse maternal and fetal outcomes. Patient‐specific risks based on angiogenic factors might better categorize those who might have a severe adverse outcome. Methods Women evaluated for suspected PE at a tertiary hospit...

description | Introduction
Preeclampsia (PE) is a pregnancy‐specific syndrome associated with adverse maternal and fetal outcomes. Patient‐specific risks based on angiogenic factors might better categorize those who might have a severe adverse outcome.
Methods
Women evaluated for suspected PE at a tertiary hospital (2009–2012) had pregnancy outcomes categorized as ‘referent’ or ‘severe’, based solely on maternal/fetal findings. Outcomes that may have been influenced by a PE diagnosis were considered ‘unclassified’. Soluble fms‐like tyrosine kinase (sFlt1) and placental growth factor (PlGF) were subjected to bivariate discriminant modeling, allowing patient‐specific risks to be assigned for severe outcomes.
Results
Three hundred twenty‐eight singleton pregnancies presented at ≤34.0 weeks' gestation. sFlt1 and PlGF levels were adjusted for gestational age. Risks above 5 : 1 (10‐fold over background) occurred in 77% of severe (95% CI 66 to 87%) and 0.7% of referent (95% CI |

Preeclampsia (PE) is a pregnancy‐specific syndrome associated with adverse maternal and fetal outcomes. Patient‐specific risks based on angiogenic factors might better categorize those who might have a severe adverse outcome.
Methods
Women evaluated for suspected PE at a tertiary hospital (2009–2012) had pregnancy outcomes categorized as ‘referent’ or ‘severe’, based solely on maternal/fetal findings. Outcomes that may have been influenced by a PE diagnosis were considered ‘unclassified’. Soluble fms‐like tyrosine kinase (sFlt1) and placental growth factor (PlGF) were subjected to bivariate discriminant modeling, allowing patient‐specific risks to be assigned for severe outcomes.
Results
Three hundred twenty‐eight singleton pregnancies presented at ≤34.0 weeks' gestation. sFlt1 and PlGF levels were adjusted for gestational age. Risks above 5 : 1 (10‐fold over background) occurred in 77% of severe (95% CI 66 to 87%) and 0.7% of referent (95% CI <0.1 to 3.8%) outcomes. Positive likelihood ratios for the modeling and validation datasets were 19 (95% CI 6.2–58) and 15 (95% CI 5.8–40) fold, respectively.
Conclusions
This validated model assigns patient‐specific risks of any severe outcome among women attending PE triage. In practice, women with high risks would receive close surveillance with the added potential for reducing unnecessary preterm deliveries among remaining women. © 2015 The Authors.

What's already known about this topic?
Angiogenic factors are associated with preeclampsia (PE), a pregnancy‐specific syndrome that can lead to severe adverse outcomes. The sFlt1/PlGF ratio has been shown to identify patients at risk for preeclampsia.
What does this study add?
We define the disorder of interest as any severe adverse outcome among women with suspected PE. Angiogenic test results are combined into patient‐specific risks to optimize translation to patient care to improve overall pregnancy outcomes.</description><identifier>ISSN: 0197-3851</identifier><identifier>EISSN: 1097-0223</identifier><identifier>DOI: 10.1002/pd.4554</identifier><identifier>PMID: 25641027</identifier><language>eng</language><publisher>England: Blackwell Publishing Ltd</publisher><subject>Adult ; Angiogenesis Inducing Agents ; Biomarkers - blood ; Birth weight ; Female ; Humans ; Infant, Newborn ; Original ; Placenta Growth Factor ; Pre-Eclampsia - diagnosis ; Preeclampsia ; Pregnancy ; Pregnancy Outcome ; Pregnancy Proteins - blood ; Risk Assessment ; Vascular Endothelial Growth Factor Receptor-1 - blood</subject><ispartof>Prenatal diagnosis, 2015-04, Vol.35 (4), p.386-393</ispartof><rights>2015 The Authors. published by John Wiley & Sons Ltd.</rights><rights>2015 The Authors.
