Introduction: The use of phosphate binders to control hyperphosphatemia may allow diets less restricted in protein and calories for maintenance hemodialysis (MHD) patients. The study compared intakes of protein, calorie and phosphate among MHD patients with different serum phosphate concentrations, taking into account binder use. The hypothesis was that low serum phosphate would be associated with low intakes of protein and calories only in patients not on binders. Methods: A cross-sectional study of 443 patients enrolled in the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO) in Salvador, Brazil, with stratified sampling on serum phosphate: ≤3.0 (n = 41), 3.5-5.5 (n = 328) and ≥7.0 mg/dL (n = 74). A 3-day diet diary was used to determine dietary intakes. Results: Approximately 49.0% confirmed binder use. Covariate-adjusted linear regression showed that associations between dietary intakes and serum phosphate were modified by the binder use. In patients not on binders, protein intake was >20% lower for serum phosphate ≤3.0 mg/dL compared to higher concentrations. Also in those not on binders, calorie intake was >30% lower for serum phosphate ≤3.0 mg/dL compared to ≥7.0 mg/dL. Differences in dietary intakes by serum phosphate were virtually absent in patients on binders. Conclusions: The results are consistent with the hypothesis that low serum phosphate is associated with low protein and calorie intake only among MHD patients not on binders. This study supports recommendations to prevent hyperphosphatemia in MHD patients by adequate combination of binder use and selection of foods restricted in phosphors but not severely restricted in protein and calories.

Alternative phosphate binders, such as CaCO3, have been shown to be effective in the control of phosphate (P) retention in hemodialysis patients (HDP). Additionally, both oral (POC) and iv (IVC) calcitriol are purported to be of benefit in the control of secondary hyperparathyroidism. This investigation was undertaken to determine: (1) the effectiveness of CaCO3 as the sole P binder in combination with low (2.5 mEq/L) Ca dialysate; (2) the effects of discontinuing Al(OH)3 binders on both unstimulated and stimulated Al concentrations; and (3) the comparative parathyroid hormone (PTH) response to both POC and IVC in a large group of hemodialysis patients. One hundred ninety-four HDP completed part 1 of the study where CaCO3 was substituted for Al(OH)3 as the sole P binder for 6 months. A cohort of 49 HDP was given desferoximine (40 mg/kg) initially and 10 months after using CaCO3. In part 2, 54 HDP were given POC and 97 HDP were given IVC in dosages of 0.25 to 0.5 micrograms/day and 1.5 to 6.0 micrograms/wk, respectively, for an additional 6 months. In part 1, Ca and P were not different from baseline values observed with Al(OH)3 therapy. Ionized Ca increased (P < 0.05) and PTH decreased (P < 0.001) during CaCO3 therapy without vitamin D. In part 2, PTH declined 23% with IVC and was unchanged with POC in equivalent dosages (P < 0.05) at 3 months. By 6 months, PTH declined a total of 54% with IVC and was unchanged with POC. Ca, ionized Ca, P, and serum calcitriol were greater (P < 0.05) in the IVC group at 6 months. Serum Al concentrations for the entire 194 HDP fell 65% (P < 0.0001) over 12 months. In the 49 HDP cohort, serum Al fell 43.6% (P < 0.001) and stimulated Al concentrations decreased 68.7% (P < 0.0001) after 10 months. We conclude that: (1) CaCO3 is as effective as Al(OH)3 in controlling P, (2) a small decrease in PTH is observed with CaCO3 alone, (3) serologic evidence of Al excess is virtually eliminated, (4) PTH suppression with IVC is superior to that seen with POC in equivalent doses.

Abstract Background Dialysis patients have to take many oral drugs, causing a high pill burden. Phosphate binders (PBs) account for a large proportion of daily pill burden; however, the relationship between patient background and prescription status of PBs is not clear. Methods We clarified the characteristics of PBs in the total daily pill burden by analyzing the drugs prescribed for 533 chronic hemodialysis patients in our facility. Results An average of nine different types of oral drugs was prescribed for each patient. The mean and median values of total pill burden were 15.1 and 14.1 pills/day/patient, respectively. The total pill burden showed a significant negative correlation with age and a significant positive correlation with dialysis vintage. In addition, the total pill burden was significantly higher in males than in females. However, there was no difference in the pill burden between patients with and without diabetes mellitus (DM). PBs were prescribed to 409 patients (76.7%), and the mean pill burden derived from PBs was 6.44 pills/day/patient. This was by far the highest of all 35 different drug categories and accounted for 32.84% of all pills. Multiple regression analysis demonstrated that independent predictors of total pill burden were age, dialysis vintage, DM, and serum phosphorus (P) levels, and all these variables, except DM, were also independent predictors of pill burden from PBs. These variables were also selected when considering the use of calcimimetics. Conclusions A high pill burden is more likely to occur in younger patients with longer dialysis vintage, DM, higher serum P levels, and prescription of calcimimetics. In addition, PB was the single largest contributor to the total pill burden that positively and linearly linked to serum P levels. Therefore, P management is a high-priority issue in the mitigation of high pill burdens in dialysis patients.

Abstract Background and Aims Hyperphosphatemia is a serious complication in chronic kidney disease (CKD) patients that serves as the main risk factor of CKD–mineral and bone disorder (CKD-MBD) progression. Previous studies suggested that iron-based phosphate binder showed better improvement in CKD-MBD parameters although the results were still inconclusive. This study aims to juxtapose the efficacies between iron-based and non-calcium phosphate binders for improving CKD-MBD parameters in dialysis-dependent (DD)-CKD patients. Method We did comprehensive searching to screen all relevant literature until November 2020 in online databases of Pubmed, EMBASE, ScienceDirect, and The Cochrane Library. We included all randomized controlled trials (RCTs) accessing the efficacies of iron-based phosphate binders (sucroferric oxyhydroxide, ferric citrate) in improving CKD-MBD parameters compared with non-calcium phosphate binders (sevelamer) in DD-CKD patients. The parameters compared in this study are changes in serum phosphate (P), serum calcium ions (Ca), fibroblast growth factors-23 (FGF23), intact parathyroid hormone (iPTH), 25-hydroxyvitamin D (calcidiol), and 1,25-dihydroxyvitamin D (calcitriol). Bias risk was accessed by using the revised Cochrane Risk-of-bias (RoB-2) tool. Analysis was performed to provide standard mean difference (SMD) with 95% confidence interval (CI) using random-effect heterogeneity test. Results Ten RCTs with total of 1,139 participants were included in this analysis. The sucroferric oxyhydroxide decreases FGF23 although not statistically significant (SMD = 0.22. 95% CI = -0.49 to 0.05, p = 0.11, I2 = 52%), but ferric citrate (SMD = -0.92. 95%CI = -1.56 to -0.29, p = 0.004, I2 = 69%) and the overall estimate (SMD = -0.45. 95% CI = -0.82 to -0.09, p = 0.02, I2 = 79%) showed significant FGF23 decline compared with sevelamer. The sucroferric oxyhydroxide showed no significant improvement of calcidiol (SMD = 0.08. 95%CI = -0.02 to 0.17, p = 0.13, I2 = 0%) and calcitriol (SMD = 0.02. 95% CI = -0.08 to 0.12, p = 0.74, I2 = 0%) compared with selevamer. There is also no significant improvement of iPTH in sucroferric oxyhydroxide subgroup (SMD = -0.14. 95%CI = -0.43 to 0.14, p = 0.32, I2 = 85%), ferric citrate subgroup (SMD = -0.02. 95%CI = -0.16 to 0.12, p = 0.80, I2 = 0%), and pooled group analysis (SMD = -0.10. 95%CI = -0.27 to 0.07, p = 0.27, I2 = 75%). Besides, this study also suggests no significant improvement comparison of serum P (SMD = -0.09. 95%CI = -0.19 to 0.02, p = 0.12, I2 = 38%) and Ca (SMD = 0.04. 95%CI = -0.12 to 0.20, p = 0.61, I2 = 57%). Conclusion There is no significant efficacies differences between iron-based and non-calcium phosphate binders for improving serum phosphate, serum calcium ions, iPTH, calcidiol, and calcitriol in dialysis-dependent chronic kidney disease patients, except for the FGF-23 parameter. However, further trials are needed to establish the juxtaposition.

Abstract Background and Aims Gut microbiome alteration increases uremic toxin levels inducing chronic inflammation and leading morbidity and mortality in patients with chronic kidney disease. Phosphate-binding agents may potentially change the composition of the gut microbiota. However, the limited clinical study investigates the microbiome difference between iron-containing and calcium-containing phosphate binders. The aim of this study was to compare the microbiota composition in hemodialysis patients treated with ferric citrate or calcium carbonate. Method The stool microbiota was investigated in hemodialysis patients with ferric citrate used (n=8) and calcium carbonate used (n=46) by 16S rRNA next-generation gene sequencing profiling. The altered microbiota between two different phosphate binders was analyzed. Differences in the microbial composition of the two patient groups were assessed using linear discriminant analysis effect size. Results Hemodialysis patients with calcium carbonate used revealed significantly reduced microbial species diversity (Shannon index and Simpson index) and increased microbial dysbiosis index compared with ferric citrate users. Compared to patients taking calcium carbonate, a distinct microbial community structure in patients taking ferric citrate, with an increased abundance of Bacteroidetes phylum and decreased abundance of phylum Firmicutes. In comparison between two phosphate binder users, members of the order Lactobacillales were prominent in calcium carbonate therapy, including family Streptococcaceae and genus Streptococcus. In contrast, taxa of the genus Ruminococcaceae, Flavonifractor, and Cronobacter were enriched in ferric citrate phosphate binder users. Conclusion The fecal microbiota was richer and more diverse in the ferric citrate group than in the calcium carbonate group. Hemodialysis patients with ferric citrate used were associated with differences in the gut microbiome composition compared to calcium carbonate users.

Gut dysbiosis in patients with chronic kidney disease (CKD) may induce chronic inflammation and increase morbidity. Phosphate-binding agents, generally used in patients with CKD, may potentially change the composition of the gut microbiota. This study aimed to compare the microbiota composition in hemodialysis patients treated with ferric citrate or calcium carbonate. The stool microbiota was investigated in hemodialysis patients treated with ferric citrate (n = 8) and calcium carbonate (n = 46) using 16S rRNA gene amplicon sequencing profiling using linear discriminant analysis of effect size. Further predictive functional profiling of microbial communities was obtained with Tax4Fun in R. Hemodialysis patients treated with calcium carbonate had a significantly reduced microbial species diversity (Shannon index and Simpson index) and an increased microbial alteration ratio compared with patients treated with ferric citrate. A distinct microbial community structure was found in patients treated with ferric citrate, with an increased abundance of the Bacteroidetes phylum and a decreased abundance of the phylum Firmicutes. Members of the order Lactobacillales were enriched in patients treated with calcium carbonate, whereas taxa of the genera Ruminococcaceae UCG-004, Flavonifractor, and Cronobacter were enriched in patients treated with ferric citrate phosphate binder. In conclusion, Ferric citrate therapy results in a more diverse microbiome community compared to calcium carbonate therapy in hemodialysis patients with phosphate binder treatment. The gut microbiome reflects the phosphate binder choice in hemodialysis patients, further affecting the physiological environment in the gastrointestinal tract.
