Resumo

Objective. To determine the possibility of diagnosing preeclampsia from the urinary peptide profile. Subject and methods. To identify candidate peptide biomarkers for preeclampsia, a case-control study was performed in women with verified moderate to severe preeclampsia. Eight urine samples were examined in each woman with moderate to severe preeclampsia and in each control woman with physiological pregnancy. The peptide fraction was analyzed using first a MALDI-TOF mass spectrometer and then a Dionex 300 nanoflow chromatographer (USA) and a Maxis time-of-flight mass spectrometer (Bruker, Bremen, Germany). The findings were processed by bioinformatics techniques. Results. This investigation has revealed both some previously known peptide biomarkers of preeclampsia and a number of novel endogenous urinary peptides specific for severe preeclampsia. Out of them, a subgroup of 6 peptides, fragments of the α-chain of fibrinogen and collagens (types I and III), as well as uromodulin, which allow determination of the development of severe preeclampsia with 100% diagnostic value, may be identified. Conclusion. The investigation has shown the high diagnostic potential of a precision analysis of endogenous peptides in the urine of pregnant women, by applying chromatography mass spectrometry. The verification of the found marker peptides calls for investigations on a larger patient sample and for inclusion of additional comparison groups to estimate the specificity of a panel of peptides.
