| Research Abstract |
A secreted isoform of receptor for advanced glycation end products (sRAGE) involves sRAGE and endogenous sRAGE (esRAGE). Pentosidine is one of an advanced glycation end product (AGE). Lectin-like oxidized LDL receptor 1 is responsible for the uptake of oxidized LDL and is released to serum in part as the soluble form (sLOX-1). Few studies addressed the pivotal roles of the AGEs-RAGE system or sLOX-1 in acute stroke patients. We measured plasma sRAGE/esRAGE, pentosidine, and sLOX-1 levels associated with clinical features in acute stroke. Both plasma sRAGE and esRAGE levels correlated with estimated glomerular filtration rate. Higher levels of plasma pentosidine compared with normal were demonstrated in patients with acute stroke. The cut off value 114 pmol/mL of pentosidine has high sensitivity (0.798) and specificity (0.800) for acute stroke. High level of sLOX-1 was examined within a week after the onset of ischemic stroke, however, they decreased at 3 month.
