BACKGROUND: Prediction of pre-eclampsia and adverse pregnancy outcomes with biomarkers has been proposed. AMH is an ovary-specific growth factor, used to predict ovarian reserve, which changes with age similar to the change in age-related fertility.
AIMS: The aim of the study was to determine whether AMH tested in the first trimester of pregnancy was associated with pregnancy hypertension or adverse pregnancy outcomes.
MATERIALS AND METHODS: Retrospective cohort study of women who delivered singleton fetuses ≥20 weeks' gestation at Royal Hospital for Women, Sydney, Australia (n = 331). AMH was tested in 2011 via Beckman-Coulter Gen II ELISA method on frozen serum collected at the time of first trimester aneuploidy screening (10-13 + 6 weeks' gestation). Outcome data were obtained from the hospital database (ObstetriX). Main outcome measures were pregnancy hypertension (pre-eclampsia and gestational hypertension) and composite adverse pregnancy outcome.
RESULTS: The median AMH level was 9.7 pmol/L (interquartile range (IQR) 3.9-17.3). There was a trend towards women with pregnancy hypertension having lower AMH levels than women without pregnancy hypertension (median 5.1 pmol/L, IQR 1.5-13.2 vs 9.4 IQR 3.9-17.3; P = 0.06). After adjusting for BMI ≥25, parity ≥1 and age ≥35, women with an AMH less than the 10th centile had a 3.3-fold increased risk of pregnancy hypertension (OR 3.3, 95% CI 1.2-8.7, P = 0.01). There were no other associations between low AMH concentration and adverse maternal or neonatal outcomes.
CONCLUSIONS: Women with a very low AMH (1.5 pmol/L) in early pregnancy may have an increased risk of pregnancy hypertension. No other adverse pregnancy outcomes were identified.
