Mortality in Kidney Disease Patients Treated with Phosphate Binders

Dietary phosphorous overload and excessive calcium intake from calcium-containing phosphate binders promote coronary artery calcification (CAC) that may contribute to high mortality of dialysis patients. CAC has been found in patients in early stages of nondialysis-dependent CKD. In this population, no study has evaluated the potential role of phosphorus binders on mortality. This study aimed to evaluate all-cause mortality as the primary end point in nondialysis-dependent CKD patients randomized to different phosphate binders; secondary end points were dialysis inception and the composite end point of all-cause mortality and dialysis inception.
