BACKGROUND: Low values of pregnancy associated plasma protein A (PAPP-A), have been shown to be associated with some poor gestational outcomes, especially those related to placental deficiency such as pre-eclampsia and fetal growth restriction as well as preterm labor. The aim of this study was to compare first trimester PAPP-A MoM values with the surfactant needs of newborns of pregnant women who had a preterm delivery. METHODS: This study included 216 pregnant women who had a preterm delivery, who were found to be in the low-risk group based on their aneuploidy screening. The women were separated into two groups based on the surfactant receipts of their newborns. A record was made of the obstetric history, birth characteristics of the preterm infants, and whether or not there was a need for surfactant. RESULTS: A comparison of the PAPP-A values of the two groups revealed that the group that received surfactant had statistically significantly lower PAPP-A values (t(–3.97) = 0.203, p <  0.001). When the cut-off value of PAPP-A was taken as 1 MoM and the gestational age was analyzed together with the birth weight, PAPP-A alone was found to be a significant independent variable for the prediction of respiratory distress syndrome (RDS) (p = 0.031; OR:8.2 (1.2–55.6)). CONCLUSIONS: The result of this study demonstrated that PAPP-A MoM values may be significant in predicting the need for surfactant in RDS, which is a frequently seen condition in the neonatal period.

OBJECTIVE: We aimed to determine the relationship between the first-trimester aneuploidy screeningma and the predicted weight at birth: Small for gestational age and large for gestational age. STUDY DESIGN: 594 low-risk pregnant women with a singleton pregnancy, who underwent first-trimester aneuploidy screening by measuring nuchal translucency, maternal serum free beta-human chorionic gonadotropin, and pregnancy-associated plasma protein-A were included in the study. Those weighing above the 3rd percentile and below the 10th percentile were defined as small for gestational age, and those over the 90th percentile were defined as large for gestational age. RESULTS: A total of 594 pregnant women were enrolled. The mean maternal age of the studied group was 28.8±5.5 years. Low maternal serum pregnancy-associated plasma protein-A levels and decreased nuchal translucency measurements were associated with the small for gestational age newborn (p<0.001 and p=0.001, respectively). There is a significant correlation with large for gestational age for newborns only with an increase in maternal serum pregnancy-associated plasma protein-A levels (p=0.001). beta-human chorionic gonadotropin levels were not associated with the birth weight (p=0.735). CONCLUSION: Maternal serum pregnancy-associated plasma protein-A levels, one of the markers in first-trimester aneuploidy screening, can be used in the prediction of small for gestational age and large for gestational age However, due to its low correlation, it is not a suitable screening test for clinical practice.

Background: Serum pregnancy-associated plasma protein-A (PAPP-A) levels fluctuate in continuation with the pregnancy and thus become an important standalone marker in monitoring the adverse outcomes that may occur in pregnancy.Methods: A prospective observational study was conducted in the department of obstetrics and gynaecology. A total of 240 pregnant women in their first trimester were included in the study. Serum PAPP-A levels were measured at 11-13+6week of gestation and were evaluated with respect to the feto-maternal outcome. The data was entered in MS excel spreadsheet and analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0.Results: The mean age of the study population was 27 years. Among the maternal pregnancy parameters, PIH, pre-term labor and Emergency LSCS were significantly associated with low (<0.5 MoM) Serum PAPP-A levels, P<0.05. All the fetal outcome measures: IUGR, IUD, low birth weight, SGA babies, prematurity and NICU admissions, were significantly associated with low (<0.5 MoM) Serum PAPP-A levels, p <0.05.Conclusions: Serum PAPP-A in the early pregnancy showed significant correlation with feto-maternal outcome. Thus, it has the potential to be used as a prognostic factor and in the management of adverse outcomes by increasing surveillance for pregnant women with high-risk factors.
