Chronic Kidney Disease and the Adiposity Paradox: Valid or Confounded?

J Ren Nutr 2019 Jan 29. Epub 2019 Jan 29.

Department of Medicine, Stanford University School of Medicine, Stanford, California; Department of Pediatrics, Stanford University School of Medicine, Stanford, California.

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.

Cholecalciferol Supplementation Did Not Change Interleukin-7 and B cell-Activating Factor Levels and CD95 Expression in B lymphocytes in Patients on Dialysis: A Randomized Pilot-Controlled Trial.

J Ren Nutr 2019 Jan 24. Epub 2019 Jan 24.

Division of Nephrology- Universidade Federal São Paulo, UNIFESP, São Paulo, São Paulo, Brazil; Post-graduate Program in Medicine, Universidade Nove de Julho/UNINOVE, São Paulo, São Paulo, Brazil.

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. Read More

Different Effects of Iron Indices on Mortality in Patients With Autosomal Dominant Polycystic Kidney Disease After Long-Term Hemodialysis: A Nationwide Population-Based Study.

J Ren Nutr 2019 Jan 22. Epub 2019 Jan 22.

Department of Internal Medicine, School of Medicine, College of Medicine, Taipei Medical University, Taipei, Taiwan R.O.C; Division of Nephrology, Department of Internal Medicine, Taipei Medical University-Shuang Ho Hospital, New Taipei City, Taiwan. Electronic address:

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.

Association of Pre-End-Stage Renal Disease Serum Albumin With Post-End-Stage Renal Disease Outcomes Among Patients Transitioning to Dialysis.

J Ren Nutr 2019 Jan 11. Epub 2019 Jan 11.

Harold Simmons Center for Kidney Disease Research and Epidemiology, Division of Nephrology and Hypertension, Department of Medicine, University of California Irvine, School of Medicine, Orange, California; Nephrology Section, Tibor Rubin VA Medical Center, Long Beach, California. Electronic address:

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. Read More

Glycemic Status and Mortality in Chronic Kidney Disease According to Transition Versus Nontransition to Dialysis.

J Ren Nutr 2019 Mar 15;29(2):82-90. Epub 2018 Nov 15.

Harold Simmons Center for Chronic Disease Research and Epidemiology, University of California Irvine School of Medicine, Orange, California; Tibor Rubin Veterans Affairs Medical Center, Long Beach, California.

Objective: The impact of glycemic control in diabetic patients with chronic kidney disease (CKD) who may or may not transition to dialysis remains uncertain, given recent interest in the conservative management of advanced CKD without dialysis therapy, which may benefit from alternative glycemic control strategies.

Design And Methods: Among a national cohort of US Veterans, we examined the association of glycemic status, defined by averaged random blood glucose and hemoglobin A1c (HbA1c), with mortality after transitioning to dialysis over 2007-2011 (Transition Cohort) compared with patients in a one-to-one matched cohort of CKD patients with diabetes who did not transition to dialysis (Nontransition Cohort).

Results: Among 17,121 patients in the Transition Cohort, averaged random glucose ≥200 mg/dL was associated with higher mortality in expanded case-mix analyses (reference: 100-<120 mg/dL): adjusted hazard ratio (95% confidence interval) 1. Read More

Global Prevalence of Protein-Energy Wasting in Kidney Disease: A Meta-analysis of Contemporary Observational Studies From the International Society of Renal Nutrition and Metabolism.

J Ren Nutr 2018 Nov;28(6):380-392

Division of Biostatistics (FT), Department of Preventive Medicine, and Division of Nephrology, Department of Internal Medicine, University of Tennessee Health Science Center, Memphis, Tennessee.

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).

Differences between Measured Total Nitrogen Losses in Spent Peritoneal Dialysate Effluent and Estimated Nitrogen Losses.

J Ren Nutr 2018 Oct 19. Epub 2018 Oct 19.

UCL Centre for Nephrology, Royal Free Hospital, University College London, London, UK. Electronic address:

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. Read More

Differences in Amino Acid Loss Between High-Efficiency Hemodialysis and Postdilution and Predilution Hemodiafiltration Using High Convection Volume Exchange-A New Metabolic Scenario? A Pilot Study.

J Ren Nutr 2019 Mar 16;29(2):126-135. Epub 2018 Oct 16.

Former Director of Territorial, Department of Nephrology and Dialysis, ASL Cagliari, Cagliari, Italy; Member of Italian Society of Nephrology, Cagliari, Italy. Electronic address:

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.

Design And Methods: Identical dialysis monitors, membranes, and dialysate/infusate were used to homogenize extracorporeal body influence. Ten patients were recruited and randomized to receive treatment with HEHD, HDFpost, and HDFpre it was used on-line dialytic water methodologies (OL); patients' AA arterial concentrations were measured at the start and on completion of dialysis; TAA from the dialyzer filter was calculated, and baseline levels were subsequently compared with findings obtained 1 year later.

The Renal Safety of L-Carnitine, L-Arginine, and Glutamine in Athletes and Bodybuilders.

J Ren Nutr 2018 Oct 16. Epub 2018 Oct 16.

Department of Clinical Pharmacy, Faculty of Pharmacy, Tehran University of Medical Sciences, Tehran, Iran.

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. Read More

Cooking Legumes: A Way for Their Inclusion in the Renal Patient Diet.

J Ren Nutr 2019 Mar 12;29(2):118-125. Epub 2018 Oct 12.

Associate Professor in Human Nutrition and Dietetics, Faculty of Health and Sports Science, University of Zaragoza, Huesca, Spain. Electronic address:

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.
