Abstract

Highlights: PIBF is produced very early in pregnancy and may help in early embryo implantation. PIBF is significantly different in women with pregnancy after IVF procedure. PIBF could be related to outcome of pregnancy women undergoing IVF procedure. Low urine and serum levels of PIBF predict pregnancy termination. Abstract: Earlier data suggest a relationship between PIBF concentrations and the outcome of pregnancy. The aim of the study was to compare serum and urine concentrations of PIBF in women with successful pregnancy after IVF with those of women without pregnancy after IVF procedure, and to evaluate the potential relation between PIBF and the outcome of pregnancy. Urine and serum were collected from 120 women, undergoing IVF. 87.5% of patients had primary infertility. 69.2% faced female causes of infertility: 10.8% tubal cause, 11.7% ovulation disorder, and 46.7% other causes of infertility. 30.8% of patients had male factor of infertility. Among non-pregnant women (42) mean concentrations of PIBF in urine and serum were significantly lower (15.8 ng/mL; 148.4 ng/mL) than in women with positive beta HCG value (78) (19.1 ng/mL; 225.9 ng/mL). In 49 patients pregnancy terminated with a term delivery, in 10 patients with pretem delivery, while in 19 patients the pregnancy terminated with a miscarriage. PIBF concentrations in urine (13.9 ± 2.8 ng/mL) and serum (124.6 ± 46.7 ng/mL) samples of women with miscarriage were significantly lower of those with preterm delivery (180.6 ± 54.4 ng/mL; 18.1 ± 4.4 ng/mL) and of those with term delivery (20.4 ± 8.5 ng/mL; 208.7 ± 114.3 ng/mL). Successful pregnancy after IVF procedure is predictable by measuring of urine and serum PIBF concentrations and could be important for predicting of early implantation and pregnancy outcome after IVF procedure and maybe to protect the risk pregnancy.
