Purpose:
Placental growth factor (PlGF) has been suggested as a possible biomarker for major placenta-related disorders such as preeclampsia and intrauterine growth restriction. However, experimental findings suggest that PlGF concentrations may be influenced by other factors besides the placenta. In the present study, we examined how acute fetal injury affects PlGF concentrations in maternal circulation. We therefore monitored PlGF concentrations in maternal circulation before and after feticide.
Methods:
A prospective comparative study was performed. Blood samples were drawn prospectively between January and July 2012, before and after feticide at predetermined time points in relation to the procedure (0, 30, 60, and 120 min). The levels of lactate dehydrogenase (LDH) in the maternal circulation were measured to detect acute tissue damage. PlGF concentrations were measured by standard human ELISA.
Results:
Following feticide (60 and 120 min), PlGF concentrations decreased significantly compared to the concentrations before feticide. LDH concentrations did not change before and after feticide.
Conclusions:
Our finding, along with the detailed review of the literature described in our work, supports a new concept in which primary fetal distress can affect PlGF concentration in maternal circulation. A large-scale study is required to strengthen our finding.

Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
