BACKGROUND Massive fetomaternal transplacental hemorrhage is not simply a problem of possible alloimunization in Rh incompatibility but also endangers the fetus (newborn) by massive anemization. Bleeding from placental vessels can occur after small trauma to the gravid uterus with mild or no clinical signs (bleeding or spotting, pain, hypertonus). The(More)
OBJECTIVE The receptor for advanced glycation end products, RAGE, plays an important role in the pathogenesis of several diseases. sRAGE, soluble receptor for advanced glycation end products, is an inhibitor of the pathological effect mediated via RAGE. The aim of this study was to assess the usefulness of measuring sRAGE concentration in pregnant women(More)
OBJECTIVES to assess the relationship between maternal and umbilical serum concentrations of matrix metalloproteinases (MMP)-2,8,9, the soluble receptor for advanced glycation end products (sRAGE) and IL-10 and premature delivery and fetal inflammation. METHODS maternal serum levels of MMPs, sRAGE, IL-10 and C-reactive protein (CRP) were determined in 67(More)
The pregnanolone isomers (PI) allopregnanolone (3alpha-hydroxy-5alpha-pregnan-20-one), pregnanolone (3alpha-hydroxy-5beta-pregnan-20-one), isopregnanolone (3beta-hydroxy-5alpha-pregnan-20-one), epipregnanolone (3beta-hydroxy-5beta-pregnan-20-one), progesterone, and estradiol were measured in 138 pregnant women. The sampling was carried out from the first(More)

OBJECTIVE The aim of this study was to determine the relationship between the parameters of individual serum lipids and the degree of intrauterine growth retardation (IUGR) of the fetus. The lipid levels were compared in fetuses with IUGR and in eutrophic fetuses and it was determined in which studied variable IUGR newborns differ from healthy newborns. (More)
OBJECTIVE The receptor for advanced glycation end products, RAGE, has been implicated in pathogenesis of many diseases. Soluble RAGE, sRAGE, extracellular domain of RAGE, is new biomarker. The aim of the study was to determine sRAGE levels in physiological pregnancy and their changes in pregnancies complicated by preterm labor or preeclampsia. DESIGN AND(More)
Pregnant women are often threatened by hypertension, symptoms of preterm labour, hepatopathy, and other. These complications might be the consequence of genetic factors together with involvement of environmental factors. We were searching for three polymorphisms Arg654Lys, Ala678Pro and Thr686Ala in exon 5, and two polymorphisms Phe802Leu, Ser827Ser/Leu in(More)
OBJECTIVES The aim of the study was to analyze polymorphisms of receptor for advanced glycation end products (RAGE) gene, and glyoxalase I gene and soluble RAGE, sRAGE, in physiological and pathological pregnancy. DESIGN AND METHODS Polymorphisms of RAGE gene (-429 T/C, -374 T/A, 557 G/A, 2184 A/G) and glyoxalase I gene (A419C) and sRAGE serum levels were(More)
