Background: Despite substantial progress in medical care, the mortality rate remains unacceptably high in dialysis patients. Evidence suggests that bone mineral dismetabolism (CKD-MBD) might contribute to this burden of death. However, to date only a few papers have investigated the clinical relevance of serum mineral derangements and the impact of different therapeutic strategies on mortality in a homogeneous cohort of south European dialysis patients. Methods: The RISCAVID study was a prospective, observational study in which all patients receiving hemodialysis (HD) in the north-western region of Toscany in June 2004 were enrolled (N=757) and followed up for 24 months. Results: At study entry, only 71 (9%) patients of the entire study cohort exhibited an optimal control of serum phosphorous (Pi), calcium (Ca), calciumX-phosphorous product (CAXPi) and intact parathyroidhormone (iPTH) according to the Kidney Disease Outcomes Quality Initiative (K/DOQI) clinical guidelines. Despite a similar prevalence, the severity of CKD-MBD appeared different to the results reported in the USA. Interestingly, none of the serum biomarkers or number of serum biomarkers within KDOQI targets was independently associated with all-cause and cardiovascular (CV) mortality. Among treatments, Sevelamer was the only drug independently associated with lower all-cause and cardiovascular mortality (p<0.001). Conclusion: The RISCAVID study highlights the difficulty of controlling bone mineral metabolism in HD patients and lends support to the hypothesis that a carefully chosen phosphate binder might impact survival in HD patients.
