Abstract

OBJECTIVE:

Aim of this study was to assess the prognostic capability of afamin to predict pregnancy complications.

METHOD:

First-trimester screening was consecutively performed in 4948 pregnant women, of whom 474 women developed pregnancy complications [gestational hypertension (n=84), pre-eclampsia (n=30), intrauterine growth restriction (n=107), preterm birth (n=44), and gestational diabetes mellitus (n=209)]. To each woman with pregnancy complications an uncomplicated pregnancy was matched for body mass index. Afamin serum concentrations were measured in 948 pregnant women at the first-trimester screening.

RESULTS:

Median afamin concentrations were significantly higher in women developing pre-eclampsia or gestational diabetes mellitus when compared to women with uncomplicated pregnancies (76mg/L vs. 65mg/L, p=0.001 and 80mg/L vs. 69mg/L, p<0.001). There was no difference in median afamin values between all other pregnancy complications and their matched controls. Increased afamin (i.e. >65mg/L) was a strong and independent predictor for the development of pre-eclampsia (risk ratio, 24.58; 95%CI, 2.82-214.12; p=0.004) as well as gestational diabetes mellitus (risk ratio, 2.07; 95%CI, 1.33-3.22; p=0.001).

CONCLUSION:

In this large nested case-control study increased afamin concentrations were a strong and independent predictor for pre-eclampsia and gestational diabetes mellitus, suggesting a potential role of afamin as predictive marker for pregnancy-related metabolic disorders.
