- Abstract
Background. Inflammation is a hallmark of chronic kidney disease (CKD) and stimulates glomerular expression of vascular adhesion molecules (VCAMs). We investigated in a general population whether estimated glomerular filtration rate (eGFR) is associated with circulating adhesion molecules, inflammation markers or both. Methods. We measured serum levels of five adhesion molecules [VCAM-1, intracellular adhesion molecule-1 (ICAM-1), P-selectin, E-selectin and monocyte chemoattractant protein-1 (MCP-1)] and seven inflammation markers [C-reactive protein (CRP), neutrophil gelatinase-associated lipocalin (NGAL), tumour necrosis factor receptor 1 (TNF-R1), TNF-α, interleukin 6 (IL-6), IL-8 and vascular endothelial growth factor] in 1338 randomly recruited people (50.8% women, mean age 51.7 years, eGFR 79.9mL/min/1.73 m2). Results. In multivariable-adjusted analyses, eGFR decreased (P≤0.004) with higher VCAM-1 (association size expressed in mL/min/1.73 m2 for a doubling of the marker, -2.99), MCP-1 (-1.19), NGAL (-1.19), TNF receptor 1 (-2.78), TNF-a (-2.28) and IL-6 (-0.94). The odds ratios of having eGFR<60 versus 60mL/min/1.73 m2 (n=138 versus 1200) were significant (P0.001) for VCAM-1 (1.77), MCP-1 (1.32), NGAL (1.26), TNF-R1 (1.49), TNF-a (1.45) and IL-6 (1.20). Compared with 24-h albuminuria, VCAM-1 increased (P<0.0001) the area under the curve from 0.57 to 0.65, MCP-1 to 0.67 and TNF-R1 to 0.79, but TNF-R1 outperformed both adhesion molecules (P<0.0001). Conclusions. In a general population, eGFR is inversely associated with circulating adhesion molecules VCAM-1 and MCP-1 and several inflammation markers, but inflammation markers, in particular TNF-R1 and TNF-a, identify patients with eGFR<60mL/min/1.73m2 more accurately.
