Abstract

Purpose: Intrauterine growth restriction, a major cause of fetal morbidity and mortality, is defined as a condition in which the fetus does not reach its genetically given growth potential. Screening for intrauterine growth restriction biomarkers in the mother's blood would be of great help for optimal pregnancy management and timing of delivery as well as for identifying fetuses requiring further surveillance during their infancies. Experimental Design: A multiplexing serological assay based on liquid chromatography–multiple-reaction-monitoring mass spectrometry is applied for distinguishing serum samples of pregnant women. Results: Assessment of concentrations of apolipoproteins and of proteins that belong to the lipid transport system is performed with maternal serum samples, consuming only 10 μL of serum per multiplex assay from each patient. Of all investigated proteins the serum concentrations of apolipoprotein B100 shows the greatest power for discriminating intrauterine growth restriction from control samples, reaching areas under curves above 0.85 in receiver-operator-characteristics analyses. Conclusions: These results indicate the potential of liquid chromatography-multiple-reaction-monitoring mass spectrometry to become of clinical importance in the future for intrauterine growth restriction risk assessment based on maternal apolipoprotein B100 serum levels.
