Abstract
OBJECTIVE
Our work aims to determine whether there is an association between first-trimester serum pregnancy-associated plasma protein A (PAPP-A) multiples of the median (MoM) value and placenta previa with or without placenta accreta spectrum disorders (PAS) in women.
PATIENTS AND METHODS
A retrospective analysis was performed on 267 patients who had first-trimester screening test results for aneuploidy, including nonadherent placenta previa (n=106), placenta previa with PAS (n=60), and control group (healthy pregnant women with previous cesarean section and normal placental location, n=101). To assess the significant difference between these groups, PAPP-A MoMs were compared.
RESULTS
The median PAPP-A MoM of 1.96 in placenta previa with PAS was significant (>0.88) in nonadherent placenta previa and 0.89 in the control group (p<0.001). Serum PAPP-A was found to be significantly associated with the severity of bleeding, such that patients with severe bleeding of 1,500 mL or more (n=54) had a higher mean PAPP-A MoM (1.93±0.69; p<0.001). Furthermore, the mean PAPP-A MoM was found to be 1.96±0.74 in the hysterectomy group and 0.89±0.47 in the conservative management group, and the difference was found to be significantly higher (p<0.001).
CONCLUSIONS
Elevated PAPP-A values in the first trimester of pregnancy may be a useful marker for identifying women at higher risk of PAS and adverse outcomes.
