Metabolic profiling of serum and urine in preeclampsia and gestational diabetes in early pregnancy

Abstract

PE and GDM are two major metabolic diseases affecting pregnancy. Individuals suffering from GDM are at an increased risk of developing PE in later gestational stages. Current study was done to evaluate first trimester serum and urine metabolome using nuclear magnetic resonance (NMR) spectroscopy to identify metabolites and pathways differentially regulated in both diseases. Serum metabolomics analysis revealed deregulation in larger group of metabolites and pathways as compared to urine between PE/GDM and NT groups. Few metabolites showed altered expression in both aliments. Perturbed metabolites have association with energy metabolism, protein metabolism, insulin sensitivity, gut microbiome and maintenance of redox balance. Deregulation in these metabolic pathways contributes to the pathology of GDM/PE. Our study revealed that serum metabolomic profile of PE and GDM shows overlap in 1st trimester of gestation. It also explored the potential of NMR metabolomics in identification of common biomolecules that could be developed into a clinical tool for early detection of both PE /GDM..
