OBJECTIVE: Obesity, defined by body mass index (BMI), is associated with lower mortality risk in patients with chronic kidney disease (CKD). BMI and % body fat (%BF) are confounded by muscle mass, while DXA derived fat mass index (FMI) overcomes this limitation. We compared the associations between obesity and mortality in persons with CKD using multiple estimates of adiposity, and determined whether muscle mass, inflammation and weight loss modify these associations. METHODS: Obesity was defined using BMI and DXA-derived FMI and %BF cut-offs in 2,852 NHANES participants with CKD from 1999-2006 and linked to the National Death Index with follow up through 2011...

OBJECTIVE: Dietary total antioxidant capacity (DTAC) has been hypothesized as being involved in health promotion and disease prevention. However, data about the association of the DTAC (as estimated by ferric reducing antioxidant power) with diabetes chronic complications are scarce. Therefore, the aim of this study was to determine the associations between the DTAC and chronic kidney disease (CKD) risk in subjects with type 2 diabetic. METHODS: The present case-control study consisted of 210 (102 cases and 108 controls) patients with type 2 diabetic who were participants of the phase 5 Tehran Lipid and Glucose Study and were classified based on their CKD status...

OBJECTIVE: Vitamin D insufficiency is highly prevalent among renal transplant recipients and in observational studies is associated with adverse outcomes. Hypercalcemia, usually due to persistent hyperparathyroidism, also commonly occurs in this population and often coexists with vitamin D insufficiency. However, concern that vitamin D supplementation might exacerbate the pre-existing hypercalcemia often leads clinicians to avoid vitamin D supplementation in such patients. This feasibility study aimed to quantify the effect on serum calcium of short-term low-dose cholecalciferol supplementation in a group of renal transplant recipients with a recent history of serum calcium levels >10 mg/dL...

BACKGROUND: End-stage renal disease results in B cell lymphopenia and low levels of vitamin D. Since the link between vitamin D deficiency and B lymphocytes dysfunction are not clear in patients with end-stage renal disease, we suggest that vitamin D adequacy and factors related to the homeostasis of these cells should be investigated. B lymphocytes homeostasis is a process mainly regulated signals of grown and death as interleukin (IL)-7, B cell-activating factor (BAFF)/BAFF-receptor and CD95 expression...

Intradialytic parenteral nutrition (IDPN) is commonly requested before recommended therapies in malnourished patients on hemodialysis. This review provides updated critical synthesis of the evidence on the use of IDPN in patients on hemodialysis. We searched MEDLINE, CINAHL, and other sources to identify evidence. Two reviewers sequentially selected studies, abstracted data, rated study quality, and synthesized evidence using predefined criteria. IDPN did not improve clinically relevant outcomes compared with dietary counseling or oral supplementation and had varied results compared with usual care in 12 studies...

OBJECTIVE: Muscle strength is frequently altered in hemodialysis patients. In the present work, five potential muscle biomarkers have been studied in their ability to assess muscular strength, muscular mass and to predict mortality of hemodialysis patients: activin-A, procollagen III N-terminal peptide, follistatin, myostatin and insulin-like growth factor-1 (IGF-1). DESIGN AND METHODS: Three independent cohorts of prevalent hemodialysis patients (2 from Liège, Belgium and 1 from Marseille, France) were considered in this observational prospective study...

OBJECTIVE: Iron supplementation and erythropoietin stimulating agents (ESAs) are essential for maintaining hemoglobin levels in hemodialysis patients. However, patients with autosomal-dominant polycystic kidney disease (PKD) have higher endogenous erythropoietin levels, so their recommended iron indices for hemodialysis patients may differ. This study evaluated iron profiles, including ferritin levels and transferrin saturation (TSAT) to identify factors affecting mortality in patients on dialysis, and those associated with mortality in patients with and without PKD...

OBJECTIVE: Obesity is clearly associated to kidney disease in adult population; however, there is scarce evidence in children and adolescents. The aim was to compare frequency of renal damage according to the presence of overweight-obesity in children and adolescents, as well as to compare nutritional and biochemical risk factors, according to the presence of kidney alterations. METHODS: Cross-sectional study; 172 children and adolescents, 6-16 years old, without malnutrition, diabetes mellitus, hypertension and independent comorbid conditions associated to obesity or kidney disease, as well as transitory causes of microalbuminuria (MA) from a Primary Health-Care Unit were included...

OBJECTIVE: The high pill burden of many phosphate binders (PBs) may contribute to increased prevalence of hyperphosphatemia and poor nutritional status observed among patients undergoing maintenance hemodialysis therapy. We examined the real-world effectiveness of sucroferric oxyhydroxide (SO), a PB with low pill burden, in managing serum phosphorus in patients with prevalent hemodialysis over a 1-year period. DESIGN: Historical cohort analyses of de-identified electronic medical records...

OBJECTIVE: Serum albumin is a marker of malnutrition and inflammation and has been demonstrated as a strong predictor of mortality in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. Yet, whether serum albumin levels in late-stage CKD are associated with adverse outcomes after the transition to ESRD is unknown. We hypothesize that lower levels and a decline in serum albumin in late-stage CKD are associated with higher risk of mortality and hospitalization rates 1 year after transition to ESRD...

OBJECTIVE: Fiber intake influences disturbances in the gastrointestinal tract and is associated with systemic inflammation in the general population. Systemic and intraperitoneal inflammation play an important role in defining outcomes in peritoneal dialysis (PD), but the relationship between dietary fiber intake and inflammatory biomarkers has not yet been reported in the population on PD. The objective of the present study is to analyze whether or not fiber intake in patients on PD is associated with serum and intraperitoneal levels of inflammatory biomarkers...

OBJECTIVES: Patients with end-stage renal disease (ESRD) treated with hemodialysis suffer a high burden of poor functional status. Poor functional status is known as a strong, consistent predictor of mortality. However, little is known about the trajectory of functional status and its association with clinical outcomes in the ESRD population. We examined the association between a change in the functional status over time and all-cause mortality among patients on hemodialysis. DESIGN AND METHODS: This was a prospective cohort study of 817 patients with ESRD on hemodialysis with repeat measures of functional status, who enrolled in the Japan Dialysis Outcomes and Practice Patterns Study phase V...

OBJECTIVES: Phase angle (PhA) is a cell health marker and has been associated with muscle mass and strength in non-kidney disease individuals. However, it is unknown whether PhA is a predictor of sarcopenia and its components in kidney transplantation patients. The aim of the present study was to associate PhA with sarcopenia and its components in kidney transplantation patients. DESIGN AND METHODS: One hundred and twenty-nine kidney transplantation individuals were evaluated in a cross-sectional study...
