Background: Patients with early and moderate stages of chronic kidney disease (CKD) have normal serum phosphate levels. Increased fibroblast growth factor-23 (FGF23) levels in these patients are responsible for maintaining normophosphatemia status by increasing the excretion of phosphate through urine. However, an increased serum FGF23 level is related to cardiomegaly, vascular calcification, CKD progression, and mortality. This study aimed to examine the effectiveness and safety of calcium carbonate use in stage 3 or 4 CKD patients with normophosphatemia. Methods: This double-blind randomized controlled trial (ClinicalTrials.gov identifier NCT03550534) included stage 3 or 4 CKD patients with normophosphatemia who visited the nephrology or endocrinology clinic at Dr. Cipto Mangunkusumo Hospital. Forty-six subjects were randomized to receive either calcium carbonate or placebo over a 12-weeks period. Urine phosphate, serum phosphate, serum calcium, and serum intact FGF23 levels were measured before and after the intervention. Results: The baseline characteristics of the two groups were similar, except for the higher prevalence of dyslipidemia in the placebo group. The CaCO3 group had shown reduced levels of FGF23 compared to the placebo group, -8.03 vs. 0.15 pg/ml respectively (p = 0.019). The median level of FGF23 showed a significant decrease only in the CaCO3 group. An increase in eGFR and a slightly decrease in urine phosphate were observed in the CaCO3 group; however, the data was found to be statistically not significant. No significant changes were noted in the serum calcium levels in both groups. Conclusion: The administration of calcium carbonate has been shown to be effective and safe for moderate CKD patients with normophosphatemia due to its effect in lowering FGF23 levels without escalating the serum calcium level.

Background and objectivesThe sodium glucose cotransporter 2 (SGLT-2) inhibitor dapagliflozin is a novel drug for the treatment of diabetes mellitus. Recent studies suggest that SGLT-2 inhibitors affect phosphate homeostasis, but their effects on phosphate-regulating hormones in patients with diabetic kidney disease are still unclear.Design, setting, participants, & measurementsWe performed a post-hoc analysis of a double-blind, randomized, crossover trial in patients with type 2 diabetes with early-stage diabetic kidney disease on stable renin–angiotensin–aldosterone system blockade, with an albumin-to-creatinine ratio between 100 and 3500 mg/g, eGFR≥45 ml/min per 1.73 m2, and glycosylated hemoglobin≥7.2% and <11.4%. Patients were randomized to dapagliflozin 10 mg/d or placebo during consecutive 6-week study periods, separated by a 6-week wash-out. We investigated effects on circulating phosphate, calcium, parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), 25-hydroxyvitamin D (25[OH]D), and 1,25-dihydroxyvitamin D (1,25[OH]2D) levels.ResultsThirty-one patients (age 62 years; 23% female) were analyzed. Compared with placebo, dapagliflozin increased serum phosphate by 9% (95% confidence interval, 4% to 15%; P=0.002), PTH increased by 16% (3% to 30%; P=0.01), FGF23 increased by 19% (0.3% to 42%; P=0.05), and serum 1,25(OH)2D decreased by −12% (−25% to 4%; P=0.12). Calcium and 25(OH)D were unaffected. We found no correlation between changes in markers of phosphate homeostasis and changes in eGFR or 24-hour albumin excretion during dapagliflozin treatment.ConclusionsDapagliflozin increases serum phosphate, plasma PTH, and FGF23. This effect was independent of concomitant changes in eGFR or 24-hour albumin excretion.

IntroductionAcute gout occurs in people with chronic kidney disease, who are commonly older people with comorbidities such as hypertension, heart disease and diabetes. Potentially harmful treatments are administered to these vulnerable patients due to a lack of clear evidence. Newly available treatment that targets a key inflammatory pathway in acute gout attacks provides an opportunity to undertake the first-ever trial specifically looking treating people with kidney disease. This paper describes the protocol for a feasibility randomised controlled trial (RCT) comparing anakinra, a novel interleukin-1 antagonist versus steroids in people with chronic kidney disease (ASGARD).Methods and analysisASGARD is a two-parallel group double-blind, double-dummy multicentre RCT comparing anakinra 100 mg, an interleukin-1 antagonist, subcutaneous for 5 days against intramuscular methylprednisolone 120 mg. The primary objective is to assess the feasibility of the trial design and procedures for a definitive RCT. The specific aims are: (1) test recruitment and retention rates and willingness to be randomised; (2) test eligibility criteria; (3) collect and analyse outcome data to inform sample and power calculations for a trial of efficacy; (4) collect economic data to inform a future economic evaluation estimating costs of treatment and (5) assess capacity of the project to scale up to a national multicentre trial. We will also gather qualitative insights from participants. It aims to recruit 32 patients with a 1:1 randomisation. Information from this feasibility study will help design a definitive trial and provide general information in designing acute gout studies.Ethics and disseminationThe London-Central Ethics Committee approved the protocol. The results will be disseminated in peer-reviewed journals and at scientific conferences.Trial registration numberEudraCT No. 2015-001787-19, NCT/Clinicalstrials.gov No.NCT02578394, pre-results, WHO Universal Trials Reference No. U1111-1175-1977.

The Difference

Abstract Background Microbial-derived uremic toxins, p-cresyl sulfate (PCS), indoxyl sulfate (IS) and indole 3-acetic acid (IAA), have been associated with the burden of chronic kidney disease (CKD). Prebiotics have emerged as an alternative to modulate the gut environment and to attenuate toxin production. This trial aims to investigate the effect of a prebiotic fructooligosaccharide (FOS) on uremic toxins of non-dialysis-dependent CKD (NDD-CKD) patients. Methods A double-blind, placebo-controlled, randomized trial was conducted for 3 months. In all, 50 nondiabetic NDD-CKD patients [estimated glomerular filtration rate (eGFR) <45 mL/min/1.73 m2], aged 18–80 years, were allocated to prebiotic (FOS, 12 g/day) or placebo (maltodextrin, 12 g/day) groups. Primary outcomes were changes in serum (total and free) and urinary (total) PCS. Secondary outcomes included changes in IS, IAA, serum markers of intestinal permeability (zonulin), gut-trophic factors (epidermal growth factor and glucagon-like peptide-2), eGFR, inflammation (high sensitive c-reactive protein and interleukin-6), homeostatic model assessment-insulin resistance, lipid profile and gastrointestinal symptoms. Results From 50 participants (54% men, 57.3 ± 14.6 years and eGFR 21.4 ± 7.6 mL/min/1.73 m2), 46 completed the follow-up. No changes in dietary intake or gastrointestinal symptoms were observed. There was a trend in the difference of serum total ΔPCS (treatment effect adjusted for baseline levels: −12.4 mg/L; 95% confidence interval (−5.6 to 0.9 mg/L; P = 0.07) and serum-free Δ%PCS [intervention −8.6 (−41.5 to 13.9%) versus placebo 3.5 (−28.8 to 85.5%); P = 0.07] between the groups. The trend in the difference of serum total ΔPCS was independent of eGFR and dietary protein:fiber ratio intake. No difference was found in urinary PCS. Aside from the decreased high-density lipoprotein cholesterol in the intervention, no differences were observed in the change of IS, IAA or other secondary outcome between the groups. Conclusions Our result suggests the potential of FOS in reducing serum total and free PCS in nondiabetic NDD-CKD patients.
