Abstract The objective of this study was to determine if the maternal serum concentration of insulin-like growth factor-binding protein-3 (IGFBP-3) at 11-13 week's gestation is altered in pregnancies that subsequently develop preeclampsia (PE). Maternal serum concentration of IGFBP-3, pregnancy-associated plasma protein-A (PAPP-A) and uterine artery pulsatility index (PI) were measured in 60 cases that developed PE, including 20 that developed early-PE requiring delivery before 34 weeks, and compared with 120 unaffected controls. In the unaffected pregnancies, the median multiple of the normal median (MoM) values of serum IGFBP-3, PAPP-A and uterine artery PI were 1.0 MoM. In late-PE, but not in early-PE, serum IGFBP-3 was significantly increased (1.16 and 1.06 MoM, respectively), whereas in early-PE, but not in late-PE, uterine artery PI was increased (1.41 and 1.11 MoM, respectively) and serum PAPP-A was decreased (0.53 and 0.87 MoM, respectively). In the PE group, there was no significant association between IGFBP-3 and either uterine artery PI (P=0.775) or maternal serum PAPP-A (P=0.275). First-trimester serum IGFBP-3 is increased in pregnancies that subsequently develop late-PE in a mechanism that is unrelated to impaired placentation, as reflected in uterine artery PI and serum PAPP-A.
