There is an ongoing market for non-calcium-containing binders, with new ones currently on trial. In the early 1980s, when nephrologists were seeking an alternative to aluminum salts for binding phosphate in the GI tract, they switched to calcium carbonate. Published: 06 August 2013 Chronic kidney disease. Data on medications were also obtained, including the use of calcium-based phosphate binders (CBPBs), vitamin D analogs, and cinacalcet during the study period. In this study we examined the effects of sevelamer versus calcium-based phosphorus binders on lipid profile, inflammatory markers such as CRP, tumor necrosis factor-α (TNF-α), IL-6, and mineral metabolism (Ca, Ca × P), among other markers in a real-world population of MHD patients who participated in the ongoing Nutritional and Inflammatory Evaluation of Dialysis Patients (NIED) study … . Lancet. During follow-up of 5 to 44 months, patients who took non–calcium-based phosphate binders were significantly less likely to die than those who took calcium-based binders (relative risk, 0.78).

Phosphate binders for adults . Ca-based phosphate. (% female). Comparison of Calcium‐Based Phosphorus Binders. Open in new tab Download slide. For adults, your healthcare professional should offer a phosphate binder called calcium acetate first. Phosphate binders are categorised according to whether they are calcium based or calcium-free. The driving force behind this search is (1) the recognition that phosphate control is difficult and remains poor and (2) Lanthanum Carbonate Delays Progression of Coronary Artery Calcification Compared With Calcium-Based Phosphate Binders in Patients on Hemodialysis: A Pilot Study Show all authors. Treatment with LC at doses of 500–3000 mg/day significantly reduces serum phosphate levels in a dose-related fashion with a significantly lower incidence of hypercalcemia and elevated calcium × phosphorus product when compared with calcium-based binders. After the necessary data were collected, it was determined whether CBPBs were being used in a manner “consistent” or “inconsistent” with the K/DOQI guidelines. Non-Ca-based. Consideration should therefore be given to timing of administration, particularly when patients are receiving concurrent antacid therapy. bias score. of calcium-based phosphate binders. Background Calcium-based and non-calcium-based phosphate binders have similar efficacy in the treatment of hyperphosphatemia; however, calcium-based binders may … The phosphorus is then passed through the stool out of the body. Effects of sevelamer and calcium-based phosphate binders on mortality in hemodialysis patients: results of a randomized clinical trial. Moreover, non-calcium based phosphate binders seem to be more economically attractive when used as a second line therapy among dialysis and non-dialysis patients [10, 11]. Journal of renal nutrition: the official journal of the Council on Renal Nutrition of the National Kidney Foundation. (Not Graded) 2009: In pa*ents with CKD stages 3–5D and hyperphosphatemia, we recommend restricng the dose of calcium-based phosphate binders…..in the presence of persistent or recurrent hypercalcemia (1B). The calcium-based phosphate binders included calcium carbonate and calcium acetate (Table 1). Phosphate binders work by binding phosphorus from foods in the stomach and the gastrointestinal (GI) tract. Patients. It has been estimated that they bind about 50% of the phosphorus from the foods we eat leaving the rest to be absorbed into the blood stream. View Article PubMed/NCBI Google Scholar 49. Disturbances of mineral metabolism are associated with significant morbidity and mortality in patients with chronic kidney disease. Some examples of phosphate binders include calcium carbonate, calcium acetate, and aluminum hydroxide. • 5.3 Both calcium-based phosphate binders and other noncalcium-, nonaluminum-, nonmagnesium-containing phosphate-binding agents (such as sevelamer HCl) are effective in lowering serum phosphorus levels (EVIDENCE) and either may be used as the primary therapy. Lanthanum carbonate, another non-calcium-based binder, has high phosphate-binding affinity, low pill burden, and works over a wide range of pH with no negative effects on bone; however, it is expensive, can produce adverse GI effects, and has uncertain long-term effects on the liver and nervous tissues because of systemic absorption and is difficult to chew. 2008;18(1):91–8. Unfortunately, some of the treatments for these disturbances also have been found to be associated with morbidity. If you can't take calcium acetate for any reason, they should talk to you about taking a different binder called calcium carbonate. Phosphate binders are substances that bind phosphates in the bloodstream and remove them from blood circulation. Takayasu Ohtake, MD, PhD 1. calcium-based phosphate binders, vascular morbidity and mortality have been inconclusive. Calcium-based versus non-calcium-based phosphate binders: effect on mortality in patients with CKD (2B) In children with CKD Stages 3a-5D, it is reasonable to base the choice of phosphate-lowering treatment on serum calcium levels.

In The Lancet, Sophie Jamal and colleagues1 report an updated systematic review and meta-analysis of the effect on mortality of treatment of chronic kidney disease hyperphosphataemia with calcium-based versus non-calcium-based phosphate binders. Follow-up. This study was funded by a pharmaceutical company. Calcium-based phosphate binders (e.g., calcium carbonate and calcium acetate) have been used in the cat (see Table 48-2). First-choice binder (monotherapy 1) is initially evaluated with the patient on side effects, tolerability and acceptance. Currently available binders have been associated with impaired outcomes (calcium-based binders) or are expensive (non-calcium-based binders). Risk of. *If initial phosphate binder is calcium based, then consider limiting its dose to 1000–1500 mg elemental calcium. 62. However, the positive calcium balance observed in several studies suggested soft-tissue deposition after calcium exposure, implicating the potentially harmful effects of generous calcium supplementation in patients with stage 3–4 CKD and normal phosphate levels [ 6 , 7 ]. All-cause and cause-specific mortality There was no difference between treatment groups with respect to all-cause mortality, the primary end point (Figure 2a). Calcium-containing phosphate binders (CCPBs) reduce serum phosphorus levels in advanced CKD. Differences (some significant) in all-cause mortality favoring non–calcium-based binders were found in dialysis patients, predialysis patients, and patients with different durations of follow-up. pmid:18089452. There is some attenuation or delay of progression of VC by the non-calcium-based phosphate binders as compared to the cal-cium containing binders [7–9]. Most studies involve small numbers of patients and evaluate intermediate out-comes such as serum levels of calcium and phosphorus, vascular compliance and vascular calcification. There is an ongoing market for non-calcium-containing binders, with new ones currently on trial. AB - Disturbances of mineral metabolism are associated with significant morbidity and mortality in patients with chronic kidney disease. the use of phosphate binders, especially calcium based binders, may actually be harmful [6]. As reported on UKidney, earlier in July 2013, Jamal et al published a systematic review comparing calcium-based phosphate binders with non-calcium-based phosphate binders in terms of their impact on cardiovascular outcomes. (mean, years). Characteristics of randomized trials included. Nevertheless, phosphate binders are ubiquitously prescribed to patients on dialysis, and often prescribed to patients with earlier stages of CKD; for which there is no evidence of benefit and some evidence that calcium-based binders (CBBs) and possibly non-CBBs may cause more harm than placebo. In depth exploration of this issue would have been interesting in order to inform decision making, especially in countries with limited health resources.
