Mineral Binding Agents, Chronic Kidney Disease
Phosphate binders are used to reduce positive phosphate balance and to lower serum phosphate levels for people with chronic kidney disease (CKD) with the aim to prevent progression of chronic kidney disease-mineral and bone disorder (CKD-MBD)
- Most studies showed increasing risk of all-cause mortality with increasing levels of serum phosphate
Recommendations from the Kidney Disease: Improving Global Outcomes (KDIGO) CKD-MBD Update Work Group:
- In patients with CKD G3a–G5D, we suggest lowering elevated phosphate levels toward the normal range (Level of recommendation: 2, Quality of evidence: C)
- In adult patients with CKD G3a–G5D receiving phosphate-lowering treatment, we suggest restricting the dose of calcium-based phosphate binders (Level of recommendation: 2, Quality of evidence: B)
- Evidence suggesting that excess exposure to calcium through diet, medications, or dialysate may be harmful across all GFR categories of CKD
In CKD G2 to G5, compared with placebo or usual care, sevelamer, lanthanum, it was not clear that iron and
calcium-based phosphate binders had an effect on all-cause death, cardiovascular death, myocardial infarction,
stroke, fracture, or coronary artery calcification
In studies of adults with CKD G5D, sevelamer may lower all-cause death compared to calcium-based binders
- However, there are no clinically important benefits of any phosphate binder on cardiovascular death, myocardial infarction, stroke, fracture or coronary artery calcification
- Sevelamer may incur less treatment-related hypercalcemia
- Sevelamer may lead to constipation
NQF 0255. Measurement of Serum Phosphorus Concentration
Measure Description: Percentage of all adult (18 years of age or older) peritoneal dialysis and hemodialysis patients included in the sample for analysis with serum or plasma phosphorus measured at least once within month.
Exclusions: Exclusions that are implicit in the denominator definition include all patients who have not been in the facility the entire reporting month. There are no additional exclusions for this measure.
