Comprehensive proteomics reveals stage-specific signatures in blood that precede diabetic kidney disease onset and progression

Diabetic kidney disease is the leading cause of kidney failure worldwide, yet the molecular events underlying disease initiation and progression remain unclear. We measured 5,420 circulating proteins in 830 adults with type 1 diabetes and examined their longitudinal associations with onset and progression of kidney disease over 10 years of follow-up. We identified 130 proteins associated with at least one outcome independent of established clinical risk factors, of which 59 replicated in an independent cohort. HAVCR1/KIM-1, GFRA1, CD14 and GDF15 predicted albuminuria onset up to a decade befor
