Objectives

To determine if low maternal serum level of pregnancy associated plasma protein A (PAPP-A) measured in early pregnancy can predict adverse pregnancy outcomes and to examine the gestational age (GA) sampling interval for these outcomes.

Methods

This was a nested case-control study from a prospective cohort of women recruited at <20 weeks of gestation in Halifax, NS. Cases (n=248) were defined as women who had a fetal loss or developed preeclampsia, severe pregnancy-induced hypertension (PIH), or small for gestational age infant (SGA). Controls (n=244) were frequency matched to cases by GA at the time of serum sampling (6 to <20 weeks GA). Participant information was obtained from questionnaires and medical chart reviews.

Results

Women with a low PAPP-A measure [0.4 MoM). However, performance as a screening test was poor [sensitivity=38.7%; specificity=81.6%; positive likelihood ratio (LR)=2.1; negative LR=0.75]. In the adjusted model, the 10-to 14-week GA period was the only time period where low PAPP-A was significantly associated with adverse outcomes.

Conclusions

Women with a low PAPP-A early in their pregnancy have twice the risk of an adverse outcome, though PAPP-A as a one-time single marker test has limited value."xsd:string
