OBJECTIVES: Our aim was to assess the vitamin B6 intake and biochemical status in a sample of children who have undergone renal transplantation. METHODS: A prospective observational study was performed in 10 pediatric renal transplant recipients to determine their vitamin B6 status through dietary assessment and serum Pyridoxal 5'-phosphate (PLP) measurement. RESULTS: Ten children (mean age of 11.9 years) had median serum PLP concentrations of 62...

OBJECTIVE: Gut dysbiosis has been implicated in the pathogenesis of chronic kidney disease (CKD). Restoring gut microbiota with prebiotic, probiotic, and synbiotic supplementation has emerged as a potential therapeutic intervention but has not been systematically evaluated in the CKD population. DESIGN AND METHODS: This is a systematic review. A structured search of MEDLINE, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials, and the International Clinical Trials Register Search Portal was conducted for articles published since inception until July 2017...

OBJECTIVE: Patients treated by peritoneal dialysis (PD) are at increased risk of muscle wasting, and clinical guidelines recommend assessing dietary intake, by calculating protein equivalent of nitrogen appearance (PNA) to assure protein sufficiency. The PNA equations were developed many years ago, and we wished to re-evaluate them by comparing estimated and measured peritoneal nitrogen losses. DESIGN AND METHODS: This is a cross-sectional observational cohort study...

OBJECTIVE: The objective of the study was to quantify the loss of total amino acids (TAAs), nonessential amino acids, essential amino acids, and branched chain amino acids (BCAAs) produced by high-efficiency hemodialysis (HEHD), postdilution hemodiafiltration (HDFpost), and predilution hemodiafiltration (HDFpre) using high ultrafiltration volumes; and to define the specific AA losses registered in HEHD, HDFpost, and HDFpre; to identify a potential metabolic and nutritional decline into protein energy wasting; to compare AA analysis of arterial blood samples taken from healthy controls and patients with end-stage renal disease undergoing hemodialysis...

One of the major concerns about taking amino acid supplements is their potential adverse effects on the kidney as a major organ involved in the metabolism and excretion of exogenous substances. The aim of this study is to review available data about renal safety of the most prominent amino acid supplements including L-arginine, glutamine and also L-carnitine as well as creatine (as amino acid derivatives) in athletes and bodybuilders. The literature was searched by keywords such as "L-carnitine", "L-arginine", "glutamine", and "kidney injury" in databases such as Scopus, Medline, Embase, and ISI Web of Knowledge...

OBJECTIVE: It has been observed that the consumption of legumes within a varied and Mediterranean diet has beneficial effects in prevention and control of many diseases, including chronic kidney disease (CKD). Recently, legumes have also been considered a good source of protein for CKD patients. However, despite their benefits, guidelines still recommend a limit to their consumption by these patients because of legumes' high potassium and phosphorus content, which are minerals whose intake must be controlled...

OBJECTIVE: Pica could be strongly implicated in nutritional status of patients on dialysis; however, very scarce data are currently available. The objective of this study was to evaluate the prevalence of pica and its association with nutritional status in dialysis patients. DESIGN AND METHODS: This is a cross-sectional study in a tertiary care teaching hospital. Four-hundred patients on dialysis, without previous pica diagnosis or transplant, pregnancy, mental illness, or infection, were included in the study...

OBJECTIVE: Adiposity influences lipid metabolism and atherosclerotic cardiovascular disease (CVD) in the general population. The aim of the present study was to assess the association between fat mass (FM) and lipid metabolism and CVD events among patients on hemodialysis (HD). METHODS: This prospective observational study examined 240 patients on prevalent HD. Blood samples were obtained before dialysis at baseline to measure lipids, high-sensitivity C-reactive protein (hs-CRP), interleukin-6, and adiponectin...

OBJECTIVE: Considering the predictive role of the relatively low urinary citrate for stone formation, especially in hypercalciuric patients, this study is aimed at comparing urine calcium to citrate (Ca/Cit) ratio in 3 groups of children, including patients with idiopathic hypercalciuria with and without renal stone as well as the healthy children. METHODS: This study was carried out on 96 children (2 to 12 years old) referred to a pediatric nephrology clinic in the city of Ahvaz, Southwest Iran...

OBJECTIVE: We aimed to analyze the relationship between the effect of total dietary fiber intake on C-reactive protein (CRP) and on oxidative stress parameters such as serum advanced glycation end products (AGEs), superoxide dysmutase (SOD), malondialdehyde, and arterial stiffness by pulse wave velocity (PWv) in maintanace hemodialysis (MHD) patients. METHODS: Among 650 MHD patients, 128 were selected according to inclusion criteria. The dietary survey was performed with a 3-day dietary history...

OBJECTIVE: Advanced glycation end products (AGEs) are uremic toxins that result from hyperglycemia, oxidative stress, and systemic inflammation. AGEs are also formed in food during cooking. On the other hand, malnutrition may contribute to AGE formation through its association with oxidative stress and inflammation. AGE accumulation can be measured by skin autofluorescence (SAF) and elevated SAF is independently associated with higher mortality on hemodialysis (HD). We aimed to investigate associations between SAF, dietary AGE intake, and markers of malnutrition in persons receiving HD...

OBJECTIVE: High consumption of trans-fatty acids (TFAs) is associated with increased mortality. DESIGN AND METHODS: Observational cohort study of 1.988 Norwegian renal transplant recipients with a median follow-up time of 9.6 years. We assessed multivariable adjusted associations between plasma levels of industrial and ruminant TFAs with patient and graft survival. Plasma phospholipid fatty acid levels were determined by gas chromatography at 10 weeks after transplantation...

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...

OBJECTIVE: To better define the prevalence of protein-energy wasting (PEW) in kidney disease is poorly defined. METHODS: We performed a meta-analysis of PEW prevalence from contemporary studies including more than 50 subjects with kidney disease, published during 2000-2014 and reporting on PEW prevalence by subjective global assessment or malnutrition-inflammation score. Data were reviewed throughout different strata: (1) acute kidney injury (AKI), (2) pediatric chronic kidney disease (CKD), (3) nondialyzed CKD 3-5, (4) maintenance dialysis, and (5) subjects undergoing kidney transplantation (Tx)...

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...
