  • How to Take Your Phosphate Binders
    How to take your phosphate binders Information for renal patients Oxford Kidney Unit Page 2 What are phosphate binders? To reduce the amount of phosphate you absorb from your food you may have been prescribed a medicine called a phosphate binder. Phosphate binders work by binding (attaching) to some of the phosphate in food. This will reduce the amount of phosphate being absorbed into your blood stream. A list of phosphate binders and how to take them is shown below. Phosphate binder How to take it Calcichew (calcium carbonate) Chew thoroughly 10-15 minutes before or immediately before food Renacet (calcium acetate) Phosex (calcium acetate) Osvaren (calcium acetate and magnesium carbonate) Swallow whole after the first Renagel 2-3 mouthfuls of food (sevelemer hydrochloride) Renvela tablets (sevelemer carbonate) Alucaps (aluminium hydroxide) Renvela powder Dissolve in 60ml of water and (sevelemer carbonate) take after the first 2-3 mouthfuls of food Fosrenol tablets Chew thoroughly towards the (lanthanum carbonate) end/immediately after each meal Fosrenol powder Mix with a small amount of (lanthanum carbonate) food and eat immediately Velphoro Chew thoroughly after the first (sucroferric oxyhydroxide) 2-3 mouthfuls The phosphate binder you have been prescribed is: ……………………………………………………………………………………………………………………………………………………….. Page 3 How many phosphate binders should I take? You should follow the dose that has been prescribed for you. Your renal dietitian can advise how best to match your phosphate binders to your meal pattern, as well as which snacks require a phosphate binder. What happens if I forget to take my phosphate binder? For best results, phosphate binders should be taken as instructed.

  • Hyperphosphataemia in Adults with Chronic Kidney Disease on Dialysis: Sucroferric Oxyhydroxide
    pat hways Hyperphosphataemia in adults with chronic kidney disease on dialysis: sucroferric oxyhydroxide Evidence summary Published: 6 January 2015 nice.org.uk/guidance/esnm51 Key points from the evidence The content of this evidence summary was up-to-date in January 2015. See summaries of product characteristics (SPCs), British national formulary (BNF) or the MHRA or NICE websites for up-to-date information. Summary Sucroferric oxyhydroxide (Velphoro) is an iron-based phosphate binder. In 1 open-label, randomised controlled trial (RCT), sucroferric oxyhydroxide at a mean dose of 1500 mg iron (3 tablets) per day was non-inferior to sevelamer carbonate at a mean dose of 6.4 g (8 tablets) per day for lowering phosphate levels in adults with chronic kidney disease (CKD) who were on haemodialysis or peritoneal dialysis. More people in the sucroferric oxyhydroxide group withdrew from the study because of adverse events. The most common adverse events with sucroferric oxyhydroxide were gastrointestinal, particularly diarrhoea and discoloured faeces. Regulatory status: Sucroferric oxyhydroxide (Velphoro) is the first iron-based phosphate binder to be licensed in Europe for the control of serum phosphate levels in adults with CKD who are on haemodialysis or peritoneal dialysis. It was launched in the UK in January 2015. © NICE 2018. All rights reserved.

  • Dorset Medicines Advisory Group
    Dorset Medicines Advisory Group SHARED CARE GUIDELINE FOR THE USE OF PHOSPHATE BINDERS IN THE MANAGEMENT OF HYPERPHOSPHATAEMIA IN PATIENTS WITH CHRONIC KIDNEY DISEASE. INDICATION This document provides guidance for the prescribing of phosphate binders for the management of hyperphosphatemia in patients receiving haemodialysis or peritoneal dialysis and patients with chronic kidney disease stage 4 or 5 who are not receiving dialysis. This shared care guideline covers adult patients under the care of the Dorset Renal Unit. Patients with chronic renal failure have reduced ability to excrete phosphate. Phosphate accumulation enhances parathyroid activity and leads to the calcification of arteries, significantly contributing to the excess cardiovascular morbidity in these patients, especially in younger age groups. Adequate control of serum phosphate levels is thought to be beneficial for the prevention of vascular and cardiac calcification in patients with renal failure and control of parathyroid hormone. A number of oral phosphate binders are available which may be used in the context of a multiple therapeutic approach. These include calcium acetate, calcium carbonate, calcium acetate/magnesium carbonate, lanthanum, sevelamer and sucroferric oxyhydroxide. These products may be used in combination with 1-hydroxycholecalciferol (alfacalcidol) or one of its analogues and/or cinacalcet to control the development of secondary hyperparathyroidism and renal bone disease. A calcium-based phosphate binder is generally used as the initial phosphate binder therapy for the treatment for hyperphosphatemia. Calcium acetate is preferred over calcium carbonate due to its lower elemental calcium content for the equivalent phosphate binding capacity, however patient preference in formulation should be taken into consideration. A non-calcium-based phosphate binder should be used in patients who cannot tolerate a calcium-based phosphate binder, whose serum calcium exceeds 2.5mmol/L or whose parathyroid levels are less than 15pmol/L.

  • Clinical Characteristics of Tumor Lysis Syndrome in Childhood Acute Lymphoblastic Leukemia
    www.nature.com/scientificreports OPEN Clinical characteristics of tumor lysis syndrome in childhood acute lymphoblastic leukemia Yao Xue1,2,22, Jing Chen3,22, Siyuan Gao1,2, Xiaowen Zhai5, Ningling Wang6, Ju Gao7, Yu Lv8, Mengmeng Yin9, Yong Zhuang10, Hui Zhang11, Xiaofan Zhu12, Xuedong Wu13, Chi Kong Li14, Shaoyan Hu15, Changda Liang16, Runming Jin17, Hui Jiang18, Minghua Yang19, Lirong Sun20, Kaili Pan21, Jiaoyang Cai3, Jingyan Tang3, Xianmin Guan4* & Yongjun Fang1,2* Tumor lysis syndrome (TLS) is a common and fatal complication of childhood hematologic malignancies, especially acute lymphoblastic leukemia (ALL). The clinical features, therapeutic regimens, and outcomes of TLS have not been comprehensively analyzed in Chinese children with ALL. A total of 5537 children with ALL were recruited from the Chinese Children’s Cancer Group, including 79 diagnosed with TLS. The clinical characteristics, treatment regimens, and survival of TLS patients were analyzed. Age distribution of children with TLS was remarkably diferent from those without TLS. White blood cells (WBC) count ≥ 50 × ­109/L was associated with a higher risk of TLS [odds ratio (OR) = 2.6, 95% CI = 1.6–4.5]. The incidence of T-ALL in TLS children was signifcantly higher than that in non-TLS controls (OR = 4.7, 95% CI = 2.6–8.8). Hyperphosphatemia and hypocalcemia were more common in TLS children with hyperleukocytosis (OR = 2.6, 95% CI = 1.0–6.9 and OR = 5.4, 95% CI = 2.0–14.2, respectively). Signifcant diferences in levels of potassium (P = 0.004), calcium (P < 0.001), phosphorus (P < 0.001) and uric acid (P < 0.001) were observed between groups of TLS patients with and without increased creatinine.

    sucroferric oxyhydroxide 500mg chewable tablets (Velphoro®) SMC No. (1035/15) Fresenius Medical Care (UK) Ltd. 6 March 2015 The Scottish Medicines Consortium (SMC) has completed its assessment of the above product and advises NHS Boards and Area Drug and Therapeutic Committees (ADTCs) on its use in NHS Scotland. The advice is summarised as follows: ADVICE: following a full submission sucroferric oxyhydroxide (Velphoro®) is accepted for use within NHS Scotland. Indication under review: For the control of serum phosphorus levels in adult chronic kidney disease (CKD) patients on haemodialysis (HD) or peritoneal dialysis (PD). It should be used within the context of a multiple therapeutic approach, which could include calcium supplement, 1,25-dihydroxy vitamin D3 or one of its analogues, or calcimimetics to control the development of renal bone disease. After 12 weeks, sucroferric oxyhydroxide was non-inferior to a non-calcium, non-aluminium- based phosphate binder at lowering serum phosphorus levels in adults with CKD, receiving HD or PD. Overleaf is the detailed advice on this product. Chairman, Scottish Medicines Consortium Published 13 April 2015 Indication For the control of serum phosphorus levels in adult chronic kidney disease (CKD) patients on haemodialysis (HD) or peritoneal dialysis (PD). It should be used within the context of a multiple therapeutic approach, which could include calcium supplement, 1,25-dihydroxy vitamin D3 or one of its analogues, or calcimimetics to control the development of renal bone disease. Dosing Information The recommended starting dose is 1,500mg iron (3 tablets) per day. Serum phosphorus levels must be monitored and the dose titrated up or down in increments of 500mg iron (1 tablet) per day every 2 to 4 weeks until an acceptable serum phosphorus level is reached, with regular monitoring afterwards.
