Brief Summary

VIKIPEDIA is a multi-centre, placebo-controlled, randomized, open-label intervention clinical trial on Peritoneal Dialysis (PD) patients. At baseline the investigators will recruit End-Stage Renal Disease patients undergoing PD and randomize them to either daily per os supplementation of 1mg menaquinone-7 or placebo for 1.5 year. The investigators will study the effect of vitamin K2 supplementation (through normalization of dp-ucMGP) on arterial stifness and the occurence of cardiovascular events. The investigators will also cosider as secondary endpoints, mortality, central aortic blood pressure and indices of 24h-ambulatory blood pressure.
