In end-stage renal disease, fetuin-A has been demonstrated to be reduced and inversely related to cardiovascular mortality. This study had 2 distinct aims. The first was to verify if circulating concentration of fetuin-A may depend on renal function in patients with chronic kidney disease (CKD). Furthermore, we analyzed the correlation of fetuin-A with the biomarker of endothelial dysfunction endothelin-1 (ET-1), and with the inflammatory cytokine interleukin-6 (IL-6).


In 108 subjects with stage 3-5 CKD, plasma levels of fetuin-A, ET-1 and IL-6 were assayed. Patients were studied first as a whole group and then were divided according to stages of CKD and fetuin-A tertiles.


Fetuin-A concentration decreased in parallel with the increase in ET-1 and IL-6 levels as renal function declined. Multiple regression analysis showed that fetuin-A was independently associated with estimated glomerular filtration rate (beta=0.386; p<0.001), IL-6 (beta=-0.393; p=0.001) and ET-1 (beta=-0.219; p=0.02), in a multivariate model including also sex, parathyroid hormone and the calcium x phosphorus product.


These results seem to indicate that in CKD, even when not severe, inflammatory processes are increased and linked to endothelial dysfunction, worsening progressively with the decline of renal function.
