Correlation Between PIF Maternal Serum Levels and Pregnancy Outcome

PIF: biomarker of pregnancy, miscarriage, premature birth, preeclampsia, placenta accreta. Except for serum hCG, no pregnancy-complication markers are widely employed to predict the need for medical intervention. Since circulating PIF is present from very early and throughout viable pregnancy, it may represent a specific biomarker candidate. PIF levels will be analyzed in serum of pregnant women in a range of settings: a) following IVF; b) index pregnancy of women with history of recurrent pregnancy loss, c) index pregnancy of women with history of placenta mediated complications such as: intrauterine growth restriction, spontaneous idiopathic preterm delivery, and preeclampsia; and d) index pregnancy in women with evidence of abnormal placentation, namely placenta accreta and related conditions.
