Objective.
To expand the search for preeclampsia (PE) metabolomics biomarkers through the analysis of acylcarnitines in first-trimester maternal serum.
Methods.
This was a nested case-control study using serum from pregnant women, drawn between 8 and 14 weeks of gestational age.
Metabolites were measured using an UPLC-MS/MS based method.
Concentrations were compared between controls ( n = 500 ) and early-onset- (EO-) PE ( n = 68 ) or late-onset- (LO-) PE ( n = 99 ) women.
Metabolites with a false discovery rate <10% for both EO-PE and LO-PE were selected and added to prediction models based on maternal characteristics (MC), mean arterial pressure (MAP), and previously established biomarkers (PAPPA, PLGF, and taurine).
Results.
Twelve metabolites were significantly different between EO-PE women and controls, with effect levels between −18% and 29%.
For LO-PE, 11 metabolites were significantly different with effect sizes between −8% and 24%.
Nine metabolites were significantly different for both comparisons.
The best prediction model for EO-PE consisted of MC, MAP, PAPPA, PLGF, taurine, and stearoylcarnitine (AUC = 0.784).
The best prediction model for LO-PE consisted of MC, MAP, PAPPA, PLGF, and stearoylcarnitine (AUC = 0.700).
Conclusion.
This study identified stearoylcarnitine as a novel metabolomics biomarker for EO-PE and LO-PE.
Nevertheless, metabolomics-based assays for predicting PE are not yet suitable for clinical implementation.
