phosphate binders in ckd

phosphate binders in ckd

. This condition is characterized by high phosphate levels and requires phosphate-lowering agents—phosphate binders. . In CKD Patients With Kidney Failure (Stage 5): •  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. All currently available oral phosphate binders have limitations of one sort or another and available data from RCTs do not show the superiority of any one binder over another. 2. Chronic kidney disease (CKD) is frequently accompanied by hyperphosphatemia. 2006 Jul;1(4):697-703 For example, Isakova et al. The demise of calcium-based phosphate binders-is this appropriate for children? Many interventions that targeted biochemical pathways suggested by association studies and suspected biological importance have yielded null or harmful results. In conclusion, phosphate binders significantly lower serum and urinary phosphorus and attenuate progression of secondary hyperparathyroidism among patients with CKD who have normal or near-normal levels of serum phosphorus; however, they also promote the progression of vascular calcification. Summary table of randomized controlled trials examining the treatment of CKD-MBD with calcium- containing phosphate binders versus calcium-free phosphate binders: study population characteristics Table S21. Noordzij M, Korevaar JC, Bos WJ et al. Observational studies of medication use should further utilize complementary methods to those employed in clinical trials, specifically, commencing follow-up when patients first initiate therapy (incident users) and performing primary analyses according to initial treatment assignment (intention-to-treat). Such recommendations necessarily imply some intervention (phosphate binders, dietary modification) for patients whose serum phosphate concentrations fall outside the recommended range, yet clinical evidence for such interventions is absent. Interventions to correct dyslipidemia, anemia and homocysteine elevation in kidney disease populations have resulted in either no benefit or unintended harm [63–65]. . 2020 Oct;35(10):1915-1923. doi: 10.1007/s00467-020-04571-x. Staging pregnancy-related acute kidney injury according to Kidney Disease: Improving Global Outcomes guidelines: what are the barriers? Finally, from a clinical perspective, extreme dietary protein restriction, and by extension phosphate restriction, failed to impact clinical outcomes in the Modification of Diet in Renal Disease study [44]. Clinical trials that employ highly practical or ‘pragmatic’ designs represent an optimal approach for determining the safety and effectiveness of phosphate binders in real-world settings. . For example, Foley et al. Curr Med Res Opin. randomized 38 stage III CKD patients to lanthanum carbonate versus placebo for 12 months [45]. . 2000 Sep 29;87(7):E10-7 The dietary management of calcium and phosphate in children with CKD stages 2-5 and on dialysis-clinical practice recommendation from the Pediatric Renal Nutrition Taskforce. We identified common genetic variants located within or near multiple mineral metabolism genes that associated with serum phosphate concentrations among 16 264 individuals without apparent kidney disease [28]. . NIH The role of calcium-containing phosphate binders (CCPBs) use as important determinants of death and cardiovascular events in predialysis hyperphosphatemic chronic kidney disease (CKD) patients remain unclear due to the absence of evidence for … However, phosphate binders only minimally impacted the serum phosphate concentration (0.3 mg/dL reduction versus no change in placebo group) or serum concentrations of PTH, FGF-23 or 1,25(OH)2D. This topic is beyond the scope this review. These studies utilized non-standard methodologies, obscuring the interpretation of results. In patients with CKD stage 5D, we suggest lowering elevated phosphorus levels toward the normal range (2C)." It is possible that one or more phosphate regulatory factors, and not phosphate directly, is responsible for observed associations with calcification and cardiovascular events in non-dialysis populations. Calcium-based phosphate binders are often used for CKD stages 3 to 5; they are inexpensive, but have a potential to cause hypercalcemia. These processes collectively result in calcification of the medial blood vessel wall (Mönckeberg's arteriosclerosis) with resultant loss of normal vessel compliance. Pro: Should phosphate binders be used in chronic kidney disease stage 3–4? Similarly, for any of the available drugs, gastrointestinal adverse effects are a possible limitation and may promote non-adherence to medication. Where diet alone is not sufficient, the use of intestinal phosphate binders is recommended (Sparkes et al. Please check for further notifications by email. Null effects of phosphate binders on these hormones may reflect insufficient blockade of gastrointestinal phosphate absorption, in part due to compensatory up-regulation of sodium–phosphate channels in the gut [41]. Palmer SC, Hayen A, Macaskill P et al. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. COVID-19 is an emerging, rapidly evolving situation. In summary, existing placebo-controlled trials of phosphate binders in CKD patients, albeit small, demonstrate null effects on serum phosphate concentrations, mineral metabolism hormones and subclinical cardiovascular disease measurements over relatively short-term follow-up. Complementary studies of chronic dialysis patients observed associations of higher serum phosphate concentrations with coronary artery calcification [8–10], suggesting a potential mechanism for associations with clinical outcomes. Cardiac calcification in adult hemodialysis patients. Nevertheless, there has been a progressive evolution of oral binders from aluminum, through calcium salts, and on to newer agents such as sevelamer and lanthanum carbonate.  |  . Moreover, guidelines for ‘recommended’ values are a recognized strategy of the pharmaceutical industry used to promote more frequent laboratory testing, thereby increasing the number of ‘abnormal’ values to be considered for treatment. The rationales for prescribing phosphate binders to CKD patients derive from studies of serum phosphate concentrations and phosphate metabolism, not phosphate binders. Nephrol Dial Transplant 2016; 31: 196–199.). . Since it does not bind with phosphorus in food, it is not necessary to give it with every meal. . In this regard, phosphate binders are considered the prime option; however, dietary phosphate restriction and intensified dialysis are also valuable supportive tools. 2008 Oct 21;118(17):1748-57 USA.gov. Accordingly, targeting the sodium-dependent phosphate co-transporter 2b by using nicotinamide as an alternative or adjunct to classical phosphate binders may be a therapeutic option for modulating serum phosphate in CKD." Studies of serum phosphate concentrations with disease in non-dialysis-requiring CKD populations have yielded mixed results [11–16]. There are several calcium-based phosphate binders including calcium carbonate-based ones such as Pronefra, Easypill Kidney Support, Renakitin, Renate, Tums, Ipakitine or Epakitin, Renaltan, Renal/Aventi KP or those based on calcium acetate. This medicine will help control the amount of phosphorus your body absorbs from the foods you eat. Raggi P, Boulay A, Chasan-Taber S et al. Several findings suggest that the phosphocentric hypothesis for CKD-MBD is incomplete. Preclinical data have shown that the combination of intestinal phosphate binders with inhibitors of active intestinal phosphate transport may enhance the phosphorus-lowering. Reliable data regarding the risks and benefits of phosphate binders must derive from studies that specifically focus on these medications, not serum phosphate concentrations or phosphate metabolism. Moreover, current knowledge is insufficient to support guidelines regarding ‘optimal’ serum phosphate concentrations in CKD. In general, these studies demonstrated progressively greater risks associated with sequentially higher serum phosphate concentrations; however, heterogeneity in analytic approaches across studies precludes definitive knowledge of the functional pattern of this relationship. 2009 Feb;20(2):397-404 Current evidence supports clinical trials of phosphate binders on clinically relevant endpoints as the next appropriate scientific step. . Phosphate binders are among the most common medications prescribed to patients with kidney failure receiving dialysis and are often used in advanced chronic kidney disease (CKD). Drugs. The addition of exogenous phosphate to cultured vascular smooth muscle cells and isolated aortic rings causes loss of the smooth muscle phenotype, expression of bone-specific markers and mineralization of the extracellular matrix [30–32]. Although dietary management may be adequate to control plasma phosphate in its early stages, most patients develop hyperphosphataemia by CKD stages 3-4 and require the addition of a phosphate binder. Benefits and harms of phosphate binders in CKD: a systematic review of randomized controlled trials. 2020 Mar;35(3):501-518. doi: 10.1007/s00467-019-04370-z. 2015 Oct;30(10):1843-52. doi: 10.1007/s00467-015-3125-3. The result is maintenance of serum phosphate concentrations within the normal laboratory range throughout most of the course of CKD at the expense of chronic disturbances in mineral metabolism hormones. Null findings from these studies should not discourage subsequent trials using clinical endpoints. Bowe AE, Finnegan R, Jan de Beur SM et al. 2015 Dec;30(12):2061-71. doi: 10.1007/s00467-014-3017-y. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Key characteristics of pragmatic trial designs include the selection of broadly inclusive study populations with minimal exclusion criteria, a focus on clinically relevant outcomes and avoidance of frequent, intense laboratory monitoring and subclinical disease measurements that may discourage retention. For example, we demonstrated a graded association of higher serum phosphate concentrations with mortality and incident myocardial infarction among 3490 male US veterans with stage III–IV CKD [11].

Interventions that correct these metabolic disturbances are typically more complex than initially understood. . Curr Med Res Opin. There are many different kinds of phosphate binders. Navaneethan SD, Sakhuja A, Arrigain S et al. First, reduction of gastrointestinal phosphate absorption using phosphate binders failed to meaningfully change PTH, FGF-23 or 1,25(OH)2D among stage III–IV CKD patients [39, 40].

Although phosphate binders reduce serum phosphate in these patients, it remains uncertain whether they improve clinical outcomes. 2007 Dec;23(12):3167-75. doi: 10.1185/030079907X242719. Tonelli M, Sacks F, Pfeffer M et al. Epub 2013 Oct 9. . Specifically, this theory posits that the loss of filtering nephrons leads to subtle phosphate retention, which subsequently signals the phosphaturic hormones parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF-23) to increase proportionate phosphate excretion through the kidneys [27, 37]. Nakano T, Ninomiya T, Sumiyoshi S et al. . Complementary laboratory work is vital for disentangling the complex pathophysiology of CKD-MBD and for suggesting new treatments for this disorder. In parallel, phosphate retention directly and indirectly inhibits the synthesis of 1,25-dihydroxyvitamin D (1,25[OH]2D), the biologically important form of vitamin D, and klotho, a co-factor for FGF-23 with important implications for aging and disease [26, 38]. The prescription of phosphate binders is motivated by evidence suggesting potential toxicity of higher serum phosphate concentrations, and by the assumption that phosphate binders can meaningfully reduce serum phosphate levels in CKD. Moreover, there were also no differences with respect to change in left ventricular mass, diastolic function, carotid-femoral pulse wave velocity or lumbar spine bone mineral density. Phosphate Binders Aluminum Salts. Calcium-based binders (calcium carbonate and calcium acetate) became the binders of choice in the 1980s and 1990s. After 40 weeks of follow-up, there were no differences between the treatment and placebo groups with respect to serum phosphate concentrations or phosphate regulatory hormones. For adults with stage 5 CKD who are on dialysis, it is recommended that serum phosphate levels be maintained at between 1.1 and 1.7 mmol/l. Such trials typically avoid hypervigilant procedures for ensuring compliance with treatment, which are clinically unrealistic, may utilize a no-treatment group in place of a formal placebo and can be completed at relatively lower costs. These include guidance on the use of oral phosphate binders, activated vitamin D compounds and analogues and calcimimetics. Which phosphate binder in which CKD patient? Block GA, Spiegel DM, Ehrlich J et al.  |  20. first demonstrated greater risks of mortality among chronic dialysis patients who had serum phosphate concentrations >6.5 compared with <6.5 mg/dL [1]. Some, but not all, studies have demonstrated associations of higher circulating phosphate concentrations with mortality … The prescription of phosphate binders is motivated by evidence suggesting potential toxicity of higher serum phosphate concentrations, and by the assumption that phosphate binders can meaningfully reduce serum phosphate levels in CKD. Voormolen N, Noordzij M, Grootendorst DC et al. Oral phosphate binders for the management of serum phosphate levels in dialysis patients.

NLM . Demonstration of reduced rates of clinical disease in such trials could lead to important health benefits for CKD patients, whereas negative results would refocus efforts to understand and treat CKD-MBD. People with chronic kidney disease (CKD) have a reduction in their capacity to remove phosphate from the body via the kidneys, so that phosphate levels in the blood and in body tissues increase as kidney function decreases.
