Abstract

Problem  Cytokines, advanced glycation end products (AGEs), and their receptor RAGE have been recently suggested to play a role in human pregnancy. In this study, we sought to determine the alterations of plasma AGEs, soluble RAGE (sRAGE), and proinflammatory cytokines in normal pregnancies and those complicated with type 1 diabetes mellitus.

Method of study  These parameters were measured in samples from healthy non-pregnant (C), diabetic non-pregnant (D), healthy pregnant (HP), and pregnant diabetic (DP) women.

Results  In the first trimester, DP showed lower sRAGE and higher AGEs compared to HP. In the DP group, significant negative correlations were seen between TNF-α and lipopolysaccharide (LPS)-stimulated ΙL-6 in the first trimester and sRAGE in the third trimester. LPS-stimulated IL-12 was positively correlated with levels of AGEs in the third trimester.

Conclusion  We detected several differences in the levels of AGEs, sRAGE, and proinflammatory cytokines between euglycemic and diabetic pregnancies.
