Although the exact pathogenesis of increased vascular calcification in CKD is not fully understood there are some very plausible hypotheses and candidates: from the very beginning disturbances in the phosphorus (P) and calcium (Ca) metabolism [25,26], altered expression of many factors, which are involved or regulate the mineral metabolism [27, 28], and perhaps most importantly chronic microinflammation which is present in CKD patients early on in the disease and comes along with increased CRP levels [29, 30] have been discussed as important pathogenetic factors.
