Dietary Data

Treatment of chronic kidney disease (CKD) mineral bone disorder (MBD) is challenging in growing children due to the high amount of calcium needed for normal bone mineralization and the required dietary phosphate restriction, which often includes intake of calcium-rich products such as milk. Therefore, enteral calcium-intake (Ca-I) was calculated.Patients: We looked at pediatric CKD-Patients aged 0–6 years.Design: We used a retrospective analysis of Ca-I from dietary data collections. Ca-I below 60% or above 100% of the D-A-CH and the KDOQI reference values were considered as severe Ca deficiency or Ca overload, respectively.Results: We had 41 children, median age 1.1 (range 0-5.8) years, body weight 7.3 (2.4–19.9) kg, and length 68 (48-105) cm at the time of first dietary data collection. Renal function was classified as CKD stage III in 20, IV in 28, V in 44, and VD in 142 dietary data collections. At the first dietary data collection, 5 children were in the CKD stage III, 10 in IV, 9 in V, and 17 were on dialysis. Only one child progressed to a higher CKD stage. In total, 234 dietary data collections were analyzed, and 65 follow-up collections were available from 33 children after a time interval of 26 (1–372) days. The median caloric intake was 120 (47–217)% of D-A-CH RDI. In 149 (63.6%) of the dietary data collections, enteral Ca-I was below the target (<100% of the D-A-CH and KDOQI RDI). Severe Ca-deficiency was found in 11 (26%) and 4 (12%) of the children at the first and second dietary data collection, respectively. In total, 11 children were on Ca-containing phosphate binders. In dietary data collection 1 and 2, there were seven children. From these, 4/7 and 4/7 patients had an enteral total Ca-I above the 100% D-A-CH-limit or above the KDOQI limit, respectively. Absolute dietary Ca-I and Ca-I normalized to body weight correlated negatively with PTH (r = −0.196, p < 0.005 and r = −0.13, p < 0.05).Conclusion: Enteral Ca-I should repeatedly be monitored in CKD children because many may may otherwise be underexposed to enteral calcium and overexposed when calcium-containing phosphate binders are given. Our findings suggest a major impact of dietary calcium supply on bone health in pediatric CKD.

Dysequilibrium in calcium and phosphate metabolism with development of secondary hyperparathyroidism (SHPT) is common in patients with chronic kidney disease (CKD) stage III and IV. Dietary phosphate restrictions and calcium based oral phosphate binders have not been effective in all subjects with SHPT, and soft tissue and vascular calcifications with an increased risk of cardiovascular death related are known consequences. Treatment with the calcimimetic Cinacalcet (Cc) has contributed to a better calcium and phosphate control in patients given hemodialysis treatment. In this retrospective study we present our experience with Cc given to ten (one year) or five (two years) patients with CKD stage III and IV and SHPT not suitable for surgery. With conventional therapy target levels of intact parathyroid hormon (iPTH) are seldomly reached the reason why an iPTH value < 300 ng/l was considered acceptable. Levels of iPTH decreased significantly after 3 months of Cc treatment and remained at the lower level. Plasma ionized-Ca (Ca) concentrations decreased initially but remained above 1.00 mmol/l in all but one patient. Phophate (P) levels increased to 1.41 ± 0.09 mmol/l (mean ± SE) leaving the Ca × P product unchanged. While patients with high iPTH needed high Cc doses up to 90 mg/day, some of the patients required very low doses 4.5-20 mg/day in order to achieve a decrease in iPTH levels. Only one patient reported gastric pain needing dose reduction and other adverse effects were not found. No changes in QT-time were observed. We experienced that Cc treatment was promising to control SHPT and stabilized the Ca-P balance in patients with CKD stage III and IV. Dosing may be challenging and laboratory values should be controlled often (monthly) as these patients may have variable response to Cc treatment. Due to the minimal knowledge about its effect on morbidity and mortality in the predialytic population further controlled studies are needed to confirm its efficacy and safety.

Dietary Sodium Restriction

BackgroundDistal diuretics are considered less effective than loop diuretics in CKD. However, data to support this perception are limited.MethodsTo investigate whether distal diuretics are noninferior to dietary sodium restriction in reducing BP in patients with CKD stage G3 or G4 and hypertension, we conducted a 6-week, randomized, open-label crossover trial comparing amiloride/hydrochlorothiazide (5 mg/50 mg daily) with dietary sodium restriction (60 mmol per day). Antihypertension medication was discontinued for a 2-week period before randomization. We analyzed effects on BP, kidney function, and fluid balance and related this to renal clearance of diuretics.ResultsA total of 26 patients (with a mean eGFR of 39 ml/min per 1.73 m2) completed both treatments. Dietary sodium restriction reduced sodium excretion from 160 to 64 mmol per day. Diuretics produced a greater reduction in 24-hour systolic BP (SBP; from 138 to 124 mm Hg) compared with sodium restriction (from 134 to 129 mm Hg), as well as a significantly greater effect on extracellular water, eGFR, plasma renin, and aldosterone. Both interventions resulted in a similar decrease in body weight and NT-proBNP. Neither approaches decreased albuminuria significantly, whereas diuretics did significantly reduce urinary angiotensinogen and β2-microglobulin excretion. Although lower eGFR and higher plasma indoxyl sulfate correlated with lower diuretic clearance, the diuretic effects on body weight and BP at lower eGFR were maintained. During diuretic treatment, higher PGE2 excretion correlated with lower free water clearance, and four patients developed mild hyponatremia.ConclusionsDistal diuretics are noninferior to dietary sodium restriction in reducing BP and extracellular volume in CKD. Diuretic sensitivity in CKD is maintained despite lower diuretic clearance.Clinical Trial registry name and registration numberDD-study: Diet or Diuretics for Salt-sensitivity in Chronic Kidney Disease (DD), NCT02875886

Introduction: Abnormalities in mineral metabolism are invariable with progressive deterioration of kidney function in chronic kidney disease (CKD). These abnormalities are documented in CKD on dialysis in our population but not on pre dialysis. So, present study aims to estimate serum vitamin D, calcium and phosphorus in CKD stage 3-5ND. Methods: It was a cross sectional study of established new CKD patients not on dialysis, vitamin D, calcium, phosphate binders and corticosteroids therapy. Blood sample was drawn for estimation of serum vitamin D, creatinine, calcium, phosphorus and albumin and CKD staging done by KDIGO (2012) criteria. SPSS software version 19 was used for data analysis and chi-squared and ANOVA test was applied as the test of significance.Results: Sixty six (51 male and 15 female) CKD patients with a mean age of 54.3±14.8 years were studied. Hypovitaminosis D (<30 ng/ml) was present in 84.8%, with deficiency (<20 ng/ml) in 50% and insufficiency (20-30) ng/ml in 34.8%. Other abnormalities observed were hypocalcemia (60.6%), hypercalcemia (1.5%) and hyperphosphatemia (63.6%) with no difference of corrected calcium, significant difference of serum phosphorus (p<0.001) with hyperphosphatemia in stage 4 and 5 CKD and vitamin D insufficiency in stage 3b, deficiency in stage 3a, 4 and 5 CKD. There was no correlation of serum vitamin D with calcium and phosphorus in different stages of CKD.Conclusion: Present study concludes that hypovitaminosis D, hypocalcemia and hyperphosphatemia is common in our pre-dialysis CKD patients and serum phosphorus raises more with reduction of GFR.

Chronic kidney disease (CKD) is associated with high risk for cardiovascular disease (CVD). Gut microbiota-dependent metabolites trimethylamine (TMA), trimethylamine N-oxide (TMAO), and dimethylamine (DMA) have been linked to CKD and CVD. We examined whether these methylamines are correlated with cardiovascular risk in CKD children. A total of 115 children and adolescents with CKD stage G1–G4 were enrolled in this cross-sectional study. Children with CKD stage G2–G4 had higher plasma levels of DMA, TMA, and TMAO, but lower urinary levels of DMA and TMAO than those with CKD stage G1. Up to 53% of CKD children and adolescents had blood pressure (BP) abnormalities on 24-h ambulatory BP monitoring (ABPM). Plasma TMA and DMA levels inversely associated with high BP load as well as estimated glomerular filtration rate (eGFR). Additionally, CKD children with an abnormal ABPM profile had decreased abundance of phylum Cyanobacteria, genera Subdoligranulum, Faecalibacterium, Ruminococcus, and Akkermansia. TMA and DMA are superior to TMAO when related to high BP load and other CV risk factors in children and adolescents with early-stage CKD. Our findings highlight that gut microbiota-dependent methylamines are related to BP abnormalities and CV risk in pediatric CKD. Further studies should determine whether these microbial markers can identify children at risk for CKD progression.

IntroductionHere we report the glycemic efficacy and safety of ertugliflozin in patients in the VERTIS CV cardiovascular outcome trial with chronic kidney disease (CKD) stage 3.Research design and methodsPrespecified and post-hoc analyses were performed in patients with an estimated glomerular filtration rate (eGFR) 30–<60 mL/min/1.73 m2 at screening. The primary endpoint was glycemic efficacy at week 18. Longer term glycemic efficacy and changes in body weight, systolic blood pressure (SBP), and eGFR were also evaluated.ResultsAmong 8246 patients in VERTIS CV, 1776 patients had CKD stage 3; 1319 patients had CKD stage 3A (eGFR 45–<60 mL/min/1.73 m2); 457 patients had CKD stage 3B (eGFR 30–<45 mL/min/1.73 m2). Week 18 least squares (LS)-mean (95% CI) placebo-adjusted changes from baseline in glycated hemoglobin (HbA1c) for 5 mg and 15 mg ertugliflozin were −0.27% (−0.37% to –0.17%) and −0.28% (−0.38% to –0.17%), respectively, for CKD stage 3 overall and −0.27% (−0.38% to –0.15%) and −0.31% (−0.43% to –0.19%), respectively, for CKD stage 3A (all p<0.001). For CKD stage 3B, the reduction in HbA1c for 5 mg ertugliflozin was −0.28% (−0.47% to –0.08%) (p=0.006) and for 15 mg ertugliflozin was −0.19% (−0.39% to 0.01%) (p=0.064). LS-mean placebo-adjusted reductions in body weight (range: −1.32 to −1.95 kg) and SBP (range: −2.42 to −3.41 mm Hg) were observed across CKD stage 3 categories with ertugliflozin. After an initial dip, eGFR remained above or near baseline with ertugliflozin treatment. The incidence of overall adverse events (AEs), symptomatic hypoglycemia, hypovolemia, and kidney-related AEs did not differ between ertugliflozin and placebo across CKD stage 3 subgroups.ConclusionsIn VERTIS CV patients with CKD stage 3A, ertugliflozin resulted in reductions in HbA1c, body weight and SBP, maintenance of eGFR, and was generally well tolerated. Results in the CKD stage 3B subgroup were generally similar except for an attenuated HbA1c response with the 15 mg dose.Trial registration numberNCT01986881.

Dietary Phosphate

Impaired phosphate excretion by the kidney leads to Hyperphosphatemia. It is an independent predictor of cardiovascular disease and mortality in patients with advanced chronic kidney disease (stage 4 and 5) particularly in case of dialysis. Phosphate retention develops early in chronic kidney disease (CKD) due to the reduction in the filtered phosphate load. Overt hyperphosphatemia develops when the estimated glomerular filtration rate (eGFR) falls below 25 to 40 mL/min/1.73 m2. Hyperphosphatemia is typically managed with oral phosphate binders in conjunction with dietary phosphate restriction. These drugs aim to decrease serum phosphate by binding ingested phosphorus in the gastrointestinal tract and its transformation to non-absorbable complexes [1].

Abstract Background and Aims Vascular calcification (VC) plays a major role in cardiovascular disease (CVD), which is one of the main causes of mortality in patients with chronic kidney disease (CKD). The study aims at early detection of breast arterial calcification (BAC) in different stages of CKD (stage 2, 3& 4) patients as an indicator of systemic VC. Method A case control study was conducted targeting CKD women, aged 18- 60 years old. The sample was divided into 3 groups; A,B,C (representing stage 2, 3 & 4 of CKD) from women who attended nephrology and Internal medicine clinics and admitted in inpatient ward in Suez Canal University Hospital. A 4th group (D) was formed as a control group and included women with normal kidney functions (each group (A, B, C, D) include 22 women). The selected participants were subjected to history taking, mammogram to detect BAC and biochemical assessment of lipid profile, Serum creatinine (Cr), Mg, P, Ca, PTH and FGF23. Results Our study detected presence of BAC in about 81.8% of hypertensive stage 4 CKD patients compared with 50% in stage 3 CKD, also in the majority of stage 4 CKD patients who had abnormal lipid profile parameters and electrolyte disturbance. Most of the variables had statistical significance regarding the presence of BAC. Conclusion Although it is difficult to determine the definite stage at which the risk of VC begins but in our study, it began late in stage 2 CKD, gradually increased prevalence through stage 3 and became significantly higher in stage 4. These results suggest that preventive strategies may need to begin as early as stage 2 CKD.
