Does arterial stiffness and decline in individuals with normal renal function/early chronic kidney disease? Context: We evaluated the temporal association between arterial stiffening and the early stage of renal functional decline. In 2053 Japanese employees with an estimated glomerular filtration rate (GFR) of > or = 60 ml/min/1.73 m(2) plus no proteinuria (40+/-8 years old) at the start, brachial-ankle pulse wave velocity (baPWV) and serum C-reactive protein (CRP) were measured before and after a 5-6-year follow-up period. After adjusting for confounding variables including serum CRP levels, higher baseline baPWV was associated with lower follow-up GFR (value expressed as per doubling: -16; 95% confidence interval: -24 to -9; P<0.01) and with higher annual rate of decline in GFR (value expressed as per doubling: -3; 95% confidence interval: -4 to -2; P<0.01). Every m/s higher baPWV was associated with a 36% increased odds (95% CI 1.09-1.70; P<0.01) for a development of a GFR <60 ml/min/1.73 m(2) at follow-up. In contrast, baseline GFR was not associated with follow-up baPWV (P=0.08) or the annual rate of change in baPWV (P=0.11).

In a Japanese occupational cohort with normal renal function/early chronic kidney disease, elevated arterial stiffness was an independent risk factor for the decline in renal function. CRP did not appear to exert any significant influence on this association. Final Decision: yes
