Impact of the NO-donor Pentaerythrithyltetrantrate on Perinatal Outcome in High-risk Pregnancies

Pregnancies resulting in IUGR and also in preeclampsia are strongly associated with typical underlying placental pathology revealing small placentas and maldevelopment of the decidual blood vessels, suggesting under-perfusion from the maternal circulation. Since nitric oxide (NO) donors can improve decreased uteroplacental perfusion without any negative effects on fetal circulation, these may prevent negative pregnancy outcomes in patients at risk.

The aim of this study is to evaluate the effectiveness of the long-lasting NO donor pentarythrithyltetranitrate (PETN) to reduce the likelihood of adverse pregnancy outcomes (intrauterine growth retardation / IUGR, perinatal death, placental abruption, and preterm delivery) in women recognized to be at risk for this outcome by abnormal uterine flow in mid gestation.

Official Title: Impact of the NO-donor Pentaerythrithyltetrantrate on Perinatal Outcome in High-risk Pregnancies: a Prospective Randomized Pilot Study

Further study details as provided by University of Jena:

Primary Outcome Measures:
  • Occurrence of perinatal death and/or IUGR defined as birth weight below the 10th percentile [ Time Frame: 19 -40 weeks of gestation ]

Secondary Outcome Measures:
  • Development of IUGR and severe IUGR defined as birth weight below the 5th percentile [ Time Frame: 19-40 weeks of gestation ]
  • Preterm birth before completed 37 weeks of gestation and very early preterm birth before completed 32 weeks of gestation [ Time Frame: 19 - 32 weeks of gestation ]
  • Development of preeclampsia [ Time Frame: 19 - 40 weeks of gestation ]
  • Any form of placental abruption [ Time Frame: 19 - 40 weeks of gestation ]
