Abstract Background and Aims Hyperphosphatemia is frequently encountered in hemodialysis patients and is an important risk factor of cardiovascular diseases. It is usually difficult to be managed by phosphate binders and hemodialysis. This study was carried out to assess the effect of nutritional education (NE) on the control of serum phosphorus level in hemodialysis patients. Method An open label, single center randomized controlled trial was conducted in the nephrology department, New Mansoura General Hospital, Egypt. One hundred hemodialysis patients were randomized into two groups; intervention Group (IG) (n=50) subjected to NE program for 3 months and Control group (CG) (n=50) received the usual care. Nutritional education was applied for the intervention group, by a trained renal dietitian, in the form of educational sessions, booklets, procures, audio visual teaching aids and patient-tailored counselling. Nutritional evaluation was done for all patients using dietary history, 24 hour diet recall sheet and malnutrition inflammation score (MIS) in addition to assessment of anthropometrics measurements and routine laboratory tests before randomization and at the end of the study. Results Three months after randomization, body mass index, waist circumference and midarm muscle circumference (MAMC) were significantly lower among IG versus the CG (p=0.04, 0.04 and 0.004 respectively). MIS score was significantly lower among the IG compared to the CG (p=0.02). Regarding laboratory tests, serum phosphorus level and calcium X phosphorus product were significantly lower among IG compared to the CG at the end of the study (p<0.001 and =0.04 respectively) with a percent change of serum phosphorus of -13.8 ± 21.41 after NE. The percentage of patients with hyperphosphatemia (> 5.5 mg/dl) were significantly lower in the IG at the end of study (p=0.04). Other laboratory tests including serum albumin, hemoglobin level, iron status and urea reduction ratio did not show any significant difference between both groups. Conclusion NE applied to dialysis patients added to the control of hyperphosphaemia without exposing the patients to the risk of malnutrition, resulting from injudicious dietary restrictions.

<b><i>Introduction:</i></b> Phosphate binders are used to treat hyperphosphatemia. Some patients have inappropriately controlled serum phosphorus levels, which may occur for many reasons, including a high pill burden and adverse events (AEs). Tenapanor selectively inhibits the passive paracellular transfer of phosphate in the gastrointestinal tract, thereby reducing serum phosphorus levels. This novel mechanism of action may contribute to improved phosphate management. The efficacy and safety of tenapanor have not been evaluated in Japanese patients with high serum phosphorus levels despite treatment with phosphate binders. This study aimed to assess the efficacy and safety of add-on tenapanor therapy for reducing serum phosphorus levels in this population. <b><i>Methods:</i></b> This multicenter, double-blind, randomized, placebo-controlled trial enrolled patients with refractory hyperphosphatemia undergoing hemodialysis. Patients were randomly assigned in a 1:1 ratio to receive tenapanor or placebo as an add-on to their phosphate binder regimen for 6 weeks. Change in serum phosphorus levels at week 6 (day 43) compared with the baseline value (day 1, week 0) (primary endpoint), achievement of target serum phosphorus levels (serum phosphorus level ≤6.0 or ≤5.5 mg/dL), and safety, based on all AEs and drug-related AEs, were among the outcomes evaluated. <b><i>Results:</i></b> In total, 24 patients were randomly assigned to the placebo group and 23 to the tenapanor group. The mean serum phosphorus level decreased from 7.01 mg/dL on day 1 to 6.69 mg/dL on day 43 in the placebo group and from 6.77 mg/dL on day 1 to 4.67 mg/dL on day 43 in the tenapanor group. In the placebo and tenapanor groups (modified intent-to-treat population), the mean (standard deviation) change in the serum phosphorus level at day 43 (last observation carried forward [LOCF]) was 0.08 (1.52) mg/dL and −1.99 (1.24) mg/dL, respectively, with a between-group difference of −2.07 (95% confidence interval: −2.89, −1.26; <i>p</i> &#x3c; 0.001). The target achievement rate (serum phosphorus level ≤6.0 mg/dL at week 6 [LOCF]) was 37.5 and 87.0% in the placebo and tenapanor groups, respectively. Diarrhea was the most common drug-related AE, and it occurred in 8.3 and 65.2% of patients in the placebo and tenapanor groups, respectively. No specific AEs were observed with add-on tenapanor or with phosphate binders. <b><i>Discussion/Conclusion:</i></b> Therapy with existing phosphate binders and add-on tenapanor resulted in a significant decrease in serum phosphorus level compared with the placebo group in patients with refractory hyperphosphatemia despite treatment with phosphate binders. No new safety signals were raised, and add-on tenapanor was generally well tolerated.

Abstract. The effect of histamine H2-receptor antagonist (famotidine) on the phosphorus-binding abilities of calcium carbonate and calcium lactate were examined in 13 chronic hemodialysis patients. In seven patients receiving calcium carbonate, famotidine (20 mg/d) was given because of gastroduodenal disorders, and calcium carbonate was replaced with calcium lactate as a phosphorus binder after 4 wk of treatment with famotidine. With the 4-wk administration of famotidine accompanied by calcium carbonate, the serum phosphorus level increased from 6.3 ± 0.9 to 7.1 ± 0.5 mg/dl (P < 0.05). However, with the substitution of calcium lactate, the serum phosphorus level decreased significantly when compared to that before substitution (6.3 ± 0.2 and 6.0 ± 0.9 mg/dl after 4 and 8 wk of substitution, respectively), despite continued administration of famotidine. Serum calcium, creatinine, alkaline phosphatase, high sensitive parathyroid hormone, blood urea nitrogen, arterial blood pH, and bicarbonate were not significantly altered during the trial period. In six control patients treated with calcium carbonate alone, there were no statistical changes in serum calcium and phosphorus levels after substitution of calcium lactate for calcium carbonate. These results suggest that famotidine significantly affects the phosphorus-binding ability of calcium carbonate, but not that of calcium lactate. A careful observation of changes in the serum phosphorus level should be required in hemodialysis patients receiving calcium carbonate and histamine H2-receptor antagonists. Calcium lactate may be useful as a phosphorus binder in such hemodialysis patients.
