    Abstract:
    INTRODUCTION: Fetuin-A plays an important role in bone turnover and vascular calcification. AIM: The aim of the study was to assess the relationship between serum fetuin-A concentrations, inflammatory and bone turnover markers of patients on maintenance hemodialysis. MATERIALS AND METHODS: The study was performed in 71 patients (21 women, 40 men) aged 60 ± 12 years on chronic dialysis because of end-stage renal failure for a period of 75 ± 57.2 months. The routine laboratory tests were performed with Modular P analyzer (Roche Diagnostics), serum concentrations of iPTH were measured using Nichols method, hsCRP and IL-6 using nephelometric techniques while fetuin-A, bone-specific alkaline phosphatase (bALP), fully carboxylated osteocalcin (cOC), undercarboxylated osteocalcin (ucOC), and fibroblast growth factor-23 (FGF-23) were measured using commercially available ELISA kits. RESULTS: Concentrations of fetuin-A were significantly positively correlated with albumin (r=0.37, p=0.003) and negatively associated with patients age (r=26, p=0.04), log (iPTH) (r=0.31, p=0.02), log (CRP) (r=0.31, p=0.02), log (IL-6) (r=0.41, p=0.001), log (ucOC) (r=-0.29, p=0.02), and log (FGF-23) (r=0.27, p=0.04). CONCLUSIONS: 1. Patients on maintenance hemodialysis suffer from severe disturbances of bone turnover. 2. Low serum fetuin-A levels are associated with increase markers of bone turnover and inflammation.
