The Prognostic Value of PGF and sFlt1 Variations Induced by the First Low-molecular-weight-heparin Injections in Women With Obstetrical Antiphospholipids Antibody Syndrome Starting a New Pregnancy and Following Treatment in Accordance With International Recommendations

The primary objective of this study is to evaluate plasmatic concentrations of free PGF and sFlt1 for blood samples taken before a first low-molecular-weight-heparin injection and also for blood samples taken on the 4th day of injections (the latter correspond to the first systematic control of platelet counts) in women who have an obstetric antiphospholipid antibody syndrome and who are initiating a new pregnancy with recommended treatment. Our goal is to test the prognostic value of these data on the occurrence of: - pregnancy loss categorized as embryonic loss (before 10 weeks gestation), fetal death (before 20 weeks gestation), stillbirths (from 20 weeks gestation to delivery), and neonatal death defined before reaching 28 days of age. - ischemic placental pathology (pre-eclampsia, retro-placental hematoma, birth of a small-for-gestational-age infant)

NCT02855047 Antiphospholipid Syndrome
MeSH: Antiphospholipid Syndrome Syndrome


Primary Outcomes

Description: The primary endpoint was a composite outcome that included any of the following events occurring after 19 completed weeks during the observed pregnancy: preeclampsia, abruptio placenta, or fetal growth restriction (< 10th percentile), summarized as the so-called placenta-mediated complications PMCs.

Measure: Presence/absence of at least one of the following: preeclampsia, abruptio placenta, or fetal growth restriction (< 10th percentile)

Time: 19 weeks gestation

Time Perspective: Prospective
