In terms of soluble biomarkers, differences by diabetes clinical classification were found for various biomarkers (pg/mL): sICAM [means(SD): normal 151.2 (61.0), IFG/IGT 242.5 (298.6), diabetes: 144.9 (117.0); p = 0.026], MPO [normal 19.0 (14.7), IFG/IGT: 16.3 (6.0), diabetes 44.1 (SD 81.6); p = 0.014], MCP-1 [normal 144.4 (51.6), IFG/IGT 146.7 (52.3), diabetes 186.8 (64.5); p = 0.045], and VEGF [normal 37.4 (34.6), IFG/IGT 36.8 (42.9), diabetes 79.7 (110.2); p = 0.019]. This evidence concerns the gene MPO and diabetes mellitus.
