Background: Pregnancy-Associated Plasma Protein (PAPP-A) is a type of metalloproteinase that stimulates cell growth and plays a role in regulating the biological activity of Insulin-like Growth Factors (IGF). This enzyme plays an important role in the development of the fetus and placenta. Therefore, in this study, the relationship between the serum PAPP-A level and Maternal-fetal obstetrics abnormalities and aneuploidies disorders were examined.
Methods: Available data were used in this retrospective cohort study. The research population was made up of women with a history of pregnancy referring to Tajrish Martyrs’ Hospital in 2018, which was approximately 15,000 people. All the prenatal aneuploidy screening tests of these patients were done in Nilou Medical Laboratory a referral Laboratory in Tehran, Iran. The data was collected using a checklist that was prepared in advance. Based on this, the demographic data of the patients was collected.
Results: The results show that most of the patients with chromosomal abnormalities had a PAPP-A level of <0.27 (p<0.001). It was found that the group of patients whose PAPP-A level was > or =3 had the highest structural anomaly (p=0.021). On the other hand, the highest maternal adverse outcomes [such as Premature Rupture of Membranes (PROM), pre-eclampsia, abortion, polyhydramnios, oligohydramnios, amniotic leakage, bleeding, and blood spotting] were in patients whose PAPP-A level was <0.27 (p<0.001). No significant difference in adverse fetal outcomes was observed in the above three groups (p=0.61).
Conclusion: In general, it can be said that the decrease in PAPP-A serum levels in pregnant mothers can be associated with maternal and fetal adverse outcomes. The occurrence of these complications can increase the risk of T18 and T21 in patients.
