Renal dietitians play a pivotal role in the ongoing management of chronic kidney disease in patients on hemodialysis. Awareness of changes to clinical practice guidelines that may impact laboratory parameters associated with chronic kidney disease-mineral and bone disorder is important for optimal patient care. In this article, the Kidney Disease: Improving Global Outcomes 2017 Clinical Practice Guideline Update recommendations related to the treatment of secondary hyperparathyroidism in adults on hemodialysis are reviewed and treatment implications for renal dietitians discussed...

OBJECTIVE: Predialysis fluid overload (FO) in hemodialysis (HD) patients is associated with an increased risk of death, further increased by the presence of inflammation. Malnutrition is also associated with outcome. Study objectives were, firstly, to investigate if the presence of FO is associated with malnutrition and whether this association is influenced by the presence of inflammation. Second, we assessed the associations of FO, malnutrition, and inflammation with outcome individually and in combination...

Concerns regarding protein and amino acid deficiencies with plant-based proteins have precluded their use in chronic kidney disease (CKD) patients. Many of these concerns were debunked years ago, but recommendations persist regarding the use of "high-biological value" (animal-based) proteins in CKD patients, which may contribute to worsening of other parameters such as blood pressure, metabolic acidosis, and hyperphosphatemia. Plant-based proteins are sufficient in meeting both quantity and quality requirements...

OBJECTIVE: Patients undergoing hemodialysis (HD) have high protein and energy requirements, and protein-energy wasting is common and associated with poor outcomes. Eating during dialysis may improve nutritional status by counteracting the catabolic effects of HD treatment; but eating during HD may be discouraged because of concerns of postprandial hypotension. However, little data are available to support this practice. In this study, we hypothesized that high-protein meals during HD do not lead to symptomatic intradialytic hypotension events...

OBJECTIVE: Toxic metabolites produced by the intestinal microbiome from animal proteins, carnitine (mainly from red meat), or phosphatidylcholine (mainly from egg yolk), have important adverse effects on cardiovascular disease. These are renally eliminated and may be termed gut-derived uremic toxins (GDUT). We hypothesized that even moderate renal impairment and intake of nutrient precursors would raise plasma levels of GDUT. DESIGN: A cohort study. SETTING: Academic medical center...

OBJECTIVE: Nutritional intervention targeting dietary intake modification is a major component of treatment for chronic kidney disease; however, little is known about the relationship between dietary intake and kidney function decline in individuals with preserved kidney function. DESIGN AND METHODS: In this prospective cohort study we examined the association of biomarkers of dietary intake with kidney function decline over a 5-year interval in 2,152 men and women with cystatin-C-based estimated glomerular filtration rate > 60 mL/minute/1...

OBJECTIVES: High prevalence of iron deficiency (ID) and cardiomyopathy have been observed in patients with end-stage kidney disease (ESKD). Our objective was to clarify associations between ID and cardiac remodeling in patients with ESKD. DESIGN AND METHODS: A cross-sectional study was conducted using 1974 Japanese patients with ESKD at the initiation of maintenance dialysis. Levels of hemoglobin (Hb), iron status, and cardiac enlargement as assessed by the cardiothoracic ratio (CTR) were determined immediately before the first hemodialysis session...

OBJECTIVES: Trace elements, which have a crucial role in metabolism and enzymatic pathways, are not routinely monitored in the blood of pediatric patients with chronic kidney disease. The present study was carried out to determine the serum levels of copper (Cu), zinc (Zn), selenium (Se), and lead (Pb) in children with ESRD who were currently receiving conservative management or were on long-term hemodialysis or continuous ambulatory peritoneal dialysis. METHODS: This study involved 200 children who met the inclusion criteria...

OBJECTIVE: Hyperphosphatemia is a common complication in patients with end-stage renal disease on hemodialysis. The mainstay of phosphate management involves a low-phosphate diet and use of phosphate binders, yet these are often insufficient. This study was the first to use behavioral change techniques to encourage the use of phosphate binders and dietary modifications through a series of Phosphate Education and Planning (PEP) talks. DESIGN AND METHODS: A total of 46 hemodialysis patients with hyperphosphatemia were enrolled...

OBJECTIVE: We hypothesized that intentional weight loss is associated with lower mortality risk, whereas unintentional weight loss is associated with higher mortality risk in chronic kidney disease (CKD). DESIGN AND METHODS: We examined this hypothesis in 872 participants with age >20 years, body mass index ≥ 25 kg/m2 and CKD from 1999-2004 National Health and Nutrition Examination Survey who reported their 1 year prior and current weights and the intent to lose weight...

Protein-energy wasting (PEW), which essentially refers to decreased body protein mass and fuel (energy) reserves, is common in advanced chronic kidney disease (CKD) patients and end-stage kidney disease patients undergoing chronic dialysis. The term PEW is used rather than protein-energy malnutrition because many causes of PEW in CKD and end-stage kidney disease patients does not involve reduced nutrient intake (e.g., catabolic illness, oxidants, biologicals lost in urine and dialysate, acidemia). The prevalence of PEW in CKD increases as glomerular filtration rate declines and is highest in chronic dialysis patients...

OBJECTIVE: This study aimed to identify dietary and fluid behaviors associated with relative interdialytic weight gain (RIDWG) (divided by the respective dry weight [DW]) by stratifying the patients according to body mass index (BMI). DESIGN AND METHODS: This was a cross-sectional, multicenter investigation. Between July 2016 and March 2017, data were collected from 4 Japanese dialysis centers in 3 cities. The patients (n = 577) were asked to reply to a self-completed questionnaire, including questions on perception about DW and dietary and fluid behaviors...

OBJECTIVE: To study whether the score proposed by the International Society of Renal Nutrition and Metabolism to define the protein energy wasting (PEW) syndrome has diagnostic validity in patients undergoing dialysis. DESIGN AND METHODS: Cross-sectional study including 468 prevalent hemodialysis patients from Canary Islands, Spain. Individual PEW syndrome criteria and the number of PEW syndrome categories were related to other objective markers of PEW using linear and logistic regression analyses: subjective global assessment, handgrip strength, bioimpedance-assessed body composition, and levels of high-sensitivity C-reactive protein...

OBJECTIVE: Excessive weight gain is common after kidney transplantation and increases cardiovascular risk. The aim of this randomized controlled trial was to determine whether an intensive nutrition and exercise intervention delivered alongside routine post-transplant care would reduce post-transplant weight gain. DESIGN: Single-blind, randomized controlled trial. SUBJECTS AND SETTING: Adult kidney transplant recipients at a regional transplant center were recruited during routine outpatient clinic visits in the first month after transplant...
