Numerous kidney biomarkers related to tubular injury, inflammation, and repair have been associated with kidney disease progression in patients with diabetes and underlying chronic kidney disease (CKD). Whether these markers are associated with incident CKD in a general population without diabetes is not well established.


In a nested case-cohort study within the Atherosclerosis Risk in Communities (ARIC) study, we evaluated the association of plasma biomarkers related to tubular injury (kidney injury molecule-1 [KIM-1]), inflammation (monocyte chemoattractant protein-1[MCP-1], soluble urokinase plasminogen activator receptor [suPAR], tumor necrosis factor receptor 1 [TNFR-1], tumor necrosis factor receptor 2 [TNFR-2]), and repair (human cartilage glycoprotein-39 [YKL-40]) and risk of incident CKD among individuals with baseline eGFR ≥ 60 mL/min and no diabetes. Biomarkers were measured at visit 4 (1996-1998). Incident CKD was defined as eGFR <60 mL/min per 1.73 m2 and ≥ 40% eGFR decline at visit 5 (2011- 2013) or end stage kidney disease through linkage with the USRDS registry.


There were 523 incident CKD cases (38 being ESRD) and 425 non-cases. Mean age was 62 years, 59% were women, and 20% were black. Mean baseline eGFR was 88 (5th- 95th percentile: 66 - 108). In multivariable analyses, there was a higher risk of incident CKD per two-fold higher concentration of KIM-1 (HR 1.35, 95% CI: 1.22 - 1.50), MCP-1 (HR 1.36, 95% CI: 1.12 -1.65), suPAR (HR 1.69, 95% CI: 1.37 - 2.08), TNFR-1 (HR 1.54, 95% CI: 1.32 - 1.80), and TNFR-2 (HR 1.69, 95% CI: 1.35 - 2.11). See Figure for results by biomarker quartile. YKL-40 was not significant.


Higher plasma levels of KIM-1, MCP-1, suPAR, TNFR-1, and TNFR-2 were associated with increased risk of incident CKD in a general population study.
