The receptor for advanced glycation end products (RAGE) has emerged as a central regulator of vascular inflammation and atherosclerosis. Soluble RAGE (sRAGE) has an anti-inflammatory effect by quenching ligands for RAGE. On the other hand, extracellular RAGE-binding protein S100A12 (EN-RAGE) shows a pro-inflammatory effect in a way, but may play pleiotropic roles related to inflammatory process. Therefore, we determined the levels of sRAGE and S100A12 in haemodialysis (HD) patients and evaluated their relationship with vascular calcification. ⋯ This study demonstrated that the circulating sRAGE level was inversely associated with VCS in HD patients independent of the S100A12 level and the severity of systemic inflammation.
