Receptor for advanced glycation end products (RAGE), its soluble form (sRAGE) and glyoxalase 1 (GLO 1) are important part of pathogenesis of many chronic diseases. The aim of this thesis was to elucidate role of sRAGE, four chosen RAGE polymorphisms and one GLO 1 polymorphism in physiologic pregnancy and in pregnancy with complications. Serum sRAGE levels were determined in healthy pregnant women (N=120) and in pregnancies complicated with threatening preterm labor (N=99), preeclampsia (N=35), intrauterine growth restriction (IUGR) (N=22) and intrahepatic cholestasis of pregnancy (ICP) (N=14). Four RAGE polymorphisms (RAGE -429T/C, -374A/T, RAGE Gly82Ser (557G/A), RAGE 2184A/G) and one glyoxalase 1 polymorphism GLO 1 Glu111Ala (419A/C) were studied in the same population of healthy pregnant women and women with pathological pregnancy. Serum sRAGE levels are low in comparison to non-pregnant controls, but they vary during the physiologic pregnancy. Serum sRAGE levels are low in the 1st trimester, increased in the 2nd trimester and again decreased in the 3rd trimester. Women with premature labor have significantly decreased serum sRAGE levels in comparison to women with threatening premature labor and in comparison to healthy pregnant women. sRAGE correlates negatively with leukocyte count in preterm...
