title: PP117. Measurement of sFlt-1 and PlGF for prediction of pregnancy associated diseases.
abstract: BACKGROUND
  Severe preeclampsia is associated with characteristic changes of sFlt-1 and PlGF levels in the maternal serum.
  
  
  OBJECTIVE
  The aim of our study is the determination of the predictive value of sFlt-1 and PlGF for preeclampsia and other pregnancy associated diseases in women with a pathological uterine Doppler measurement during the second trimester of pregnancy.
  
  
  METHODS
  An updated analysis of an ongoing prospective trial will be presented. Criterion of inclusion was a bilateral pathological uterine Doppler measurement with an increase of the resistance index (RI) >95th percentile and/or a bilateral postsystolic notch during 19 and 24 weeks. Ratio of sFlt-1 and PlGF was repeatedly measured during pregnancy using a full-automated system (Elecsys®, Roche).
  
  
  RESULTS
  Presently, we recruited 36 patients. Full data are available from 17 patients. Out of these in 23.5% (n=4) a delivery before 37 weeks was indicated. 41% of all newborns (7/17) showed a birth weight <5th percentile. 23.5% of all patients developed a hypertensive pregnancy disorder but without fulfilling the criterions of preeclampsia. Only two patients had a sFlt-1/PlGF ratio >95th percentile. In both cases we found severe fetal growth retardation. One of them developed a pregnancy related hypertension based on an antiphospholipid syndrome.
  
  
  CONCLUSIONS
  The additional measurement of the sFlt-1/PlGF ratio in a high risk group of pregnancies may improve the prediction of severe pregnancy related diseases during the second trimester. But keeping the low incidence of severe preeclampsia in mind, the measurements seem to be only usefulness in a high risk population. Although we reported presently only of a small part of our study population the sFlt-1/PlGF ratio did not revealed a good specificity for prediction of preeclampsia. Pathological values were also found in cases with fetal growth retardation without signs of preeclampsia.
