Serum fetuin-A concentration and fetuin-A-containing calciprotein particles in patients with chronic inflammatory disease and renal failure

Abstract

Aim Fetuin-A (Fet-A) is an important regulator of extracellular matrix mineralization. Fet-A plays a critical role in the formation and stabilization of high molecular weight colloidal protein-mineral complexes known as calciprotein particles (CPP). The aim of this study was to examine the effects of inflammation, renal function and dialysis modality on serum Fet-A and CPP. Methods This is an observational study of patients with chronic kidney disease (CKD) and those with chronic inflammatory disease (CID) but normal renal function. Serum CPP were quantified indirectly by analysing the apparent reduction in serum Fet-A concentration (reduction ratio, RR) after high-speed centrifugation. Resu..
