BACKGROUND: Volume overload results in higher mortality rates in patients on continuous ambulatory peritoneal dialysis (CAPD). The ratio of bioimpedance (RBI) might be a helpful parameter in adjusting dry body weight in CAPD patients. This study examined whether it is possible to distinguish between non-hypervolemic status and hypervolemic status in CAPD patients by using only RBI. METHODS: RBI was calculated as follows: RBI = impedance at 50 kHz/impedance at 500 kHz...

Background/Aims: As numbers of maintenance hemodialysis patients are growing, debilitating conditions of muscle wasting and atrophy are becoming some of the greatest concerns in end-stage renal disease patients. Exercise training has various potential benefits in terms of prevention of a sustained decline in functional status. This study aimed to evaluate the physical, psychological, laboratory, and dialysis-related effects of intradialytic exercise. Methods: We enrolled 22 patients from a hemodialysis center for a 6-month non-randomized prospective trial...

PURPOSE OF REVIEW: Volume management in hemodialysis patients is often challenging. Assessing volume status and deciding how much fluid to remove during hemodialysis, the so-called ultrafiltration rate (UFR), has remained a conundrum. RECENT FINDINGS: To date there is no objective assessment tool to determine the needed UFR during each hemodialysis session. Higher volume overload or higher UFR is associated with poor outcomes including worse mortality and unfavorable clinical outcomes...

INTRODUCTION: In France in 2014, there were approximately 1500 patients of reproductive age treated by dialysis. Pregnancy in these patients remains rare, however, the incidence has increased since the 2000s, with a parallel increase in the fetal survival rate. We report 2 cases of pregnancy in short-daily home hemodialysis using low dialysate flow rate. METHODS: Short-daily hemodialysis was continued at the request of the patients. The treatment consisted in an increase of frequency and duration of hemodialysis sessions, an independent blood pressure and dry weight control supervised by nephrological monitoring twice a month and a regular obstetrics follow-up...

BACKGROUND: Because chronic fluid volume overload is associated with higher mortality, we tested whether blood-volume monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) would facilitate dry weight reduction, in comparison to conventional dialysis (CONV). METHODS: We carried out a multicenter, 4-week, randomized controlled trial in hemodialysis patients ≥15% above normal extracellular fluid volume (ECV), per bioimpedance spectroscopy, who were randomized 1:1:1...

Volume overload is common and associated with adverse outcomes in the hemodialysis population including systemic hypertension, pulmonary hypertension, left ventricular hypertrophy, and mortality. Since the beginning of the era of maintenance dialysis, prescribing and maintaining a dry weight remains the standard of care for managing volume overload on hemodialysis. Reducing dry weight even by relatively small amounts has been shown to improve blood pressure and has been associated with reductions in left ventricular hypertrophy...

OBJECTIVE: Protein energy wasting is difficult to assess in pediatric hemodialysis (HD) populations because of fluid shifts. Body composition (BC) analysis aids in monitoring nutrition therapy's effects on fat and lean mass. Air displacement plethysmography (ADP) is a "practical" gold standard for fat mass (FM) measurements. We aim to compare BC measures in a pediatric HD population via anthropometry, ADP, and bioelectrical impedance (BIA). DESIGN: The study was prospective cohort study and the setting was 1 pediatric HD unit in Houston, Texas...

Hypertension is a leading cause of cardiovascular complications in children on dialysis. Volume overload and activation of the renin-angiotensin-aldosterone system play a major role in the pathophysiology of hypertension. The first step in managing blood pressure (BP) is the careful assessment of ambulatory BP monitoring. Volume control is essential and should start with the accurate identification of dry weight, based on a comprehensive assessment, including bioimpedance analysis and intradialytic blood volume monitoring (BVM)...

BACKGROUND: Hypothesizing that statins may be useful as adjuvant treatment for renal anemia, we examined the association between statin prescription (Rx) and erythropoiesis-stimulating agent (ESA) hyporesponsiveness in Japanese hemodialysis (HD) patients prescribed ESAs. METHODS: We examined 3,602 patients in 60 HD facilities dialyzed 3 times/week for ≥4 months from the Japan Dialysis Outcomes and Practice Patterns Study phases 3-5 (2005-2015). Statin Rx was reported at the end of a 4-month interval (baseline) for each patient...

Malignancy is a major cause of mortality in dialysis patients. Although molecular-targeted anticancer drugs, including tyrosine-kinase inhibitors, are used for advanced renal cell carcinoma treatment, there are few reports on their effectiveness and safety in dialysis patients. Renal cell carcinoma dialysis patients treated at our hospital from 2010 to 2013 participated in this study. Thirteen patients were treated with tyrosine-kinase inhibitors and 15 patients with surgery only (control group). During treatment, blood pressure changes and dry weight reduction tended to be greater in the tyrosine-kinase inhibitor group than in controls...

BACKGROUND: Malnutrition is common in patients undergoing haemodialysis (HD). Several studies have described different nutritional parameters as mortality predictors but few have studied whether there are differences between genders. This study aimed to evaluate which nutrition parameters may be associated with mortality in patients undergoing long-term HD depending on their gender. METHODS: Longitudinal prospective multicentre study with 12 months of follow-up...

Hypertension (HT) is present in more than 80% of patients undergoing hemodialysis (HD). Elevated blood pressure (BP) in hemodialysis patients is associated with cardiovascular events and mortality only when BP is recorded with home or ambulatory monitoring, since pre- and post-dialysis measurements are not valid estimates of BP levels during the inter-dialytic interval. Sodium and water overload is the most important of several mechanisms involved in HT development in HD. In this context, non-pharmacologic measures to ensure water and sodium balance by achieving patient dry weight and decreasing daily sodium intake, through modification of sodium level in the diet or in dialysis dialysate, are fundamental for HT control...

BACKGROUND: The characteristics of peritoneal membrane transport differ among patients, affecting the prescription of peritoneal dialysis (PD) modality and glucose exposure in order to achieve an effective dialysis. This study aims to verify the influence of glucose exposure load and peritoneal membrane transport on body composition and nutritional status changes after the first year of PD. METHODS: We examined a cohort of 85 incident PD patients during the first year of treatment...

INTRODUCTION: Volume overload and the renin-aldosterone-angiotensin system (RAAS) are 2 major factors contributing to hypertension (HTN) among hemodialysis (HD) patients. Although volume-dependent components of HTN can be corrected by appropriate volume removal, a proportion of HD patients experience elevated blood pressure (BP) despite achieving euvolemic and ideal dry weight. METHOD AND ANALYSIS: A single center, prospective, randomized, parallel design, single-blind trial will be conducted in the Malaysian state of Kelantan among postdialysis euvolemic hypertensive patients that are on regular dialysis at least 3 times a week...

Accurate dry weight estimation (DW) to achieve euvolemia is one of the key objectives of hemodialysis (HD). While conventionally DW is estimated by clinical examination, bioelectrical impedance analysis (BIA) has been proposed as an objective method to determine DW and has been tested extensively in the Western population. We aim to validate BIA for determining DW in a Pakistani population against the conventional clinician's method. This is a single-center validation study conducted at two outpatient HD units of Aga Khan Hospital, Karachi...

REVIEW
Dana C Miskulin, Daniel E Weiner
Despite having thousands of blood pressure (BP) readings on individual dialysis patients over the course of a year, our knowledge about the optimal assessment of BP, the mechanisms underlying hypertension and its management remain incomplete. Observational studies reveal that BP is lower at home than when measured in the dialysis unit. However, we do not know if using home vs. in-center measurements to guide treatment decisions improves BP control and/or clinical outcomes. Moreover, a recent US study suggests that typical hemodialysis patients are unlikely to adhere to home monitoring over the long term...

BACKGROUND: Serum N-terminal probrain natriuretic peptide (NT-proBNP) level is known to be strongly associated with fluid overload, and serves as a guide for fluid management in patients on hemodialysis (HD). This study aimed at investigating the relationship between NT-proBNP level and blood pressure (BP), ultrafiltration/dry weight ratio as well as hemoglobin, and to explore the optimal cutoff point of NT-proBNP level in Chinese patients on HD. METHODS: A total of 2306 patients on maintained HD for stage 5 chronic kidney disease (CKD) were included in this prospective study...

BACKGROUND: Continuous intradialytic calf bioimpedance spectroscopy (cBIS) allows assessment of changes in calf extracellular fluid volume (ECV) to determine dry weight (DW) in hemodialysis patients. During dialysis, calf ECV decreases until excessive ECV has been removed and normalized resistivity ρN,5 rises to values comparable to those of a normal population (cBIS-DW). It is not clear whether chronic kidney disease (CKD) itself influences ρN,5 and whether normal values depend on race and ethnicity...

BACKGROUND: In conventional hemodialysis (HD) treatment, excessive water removal sometimes induces a rapid drop in blood pressure. Intermittent infusion hemodiafiltration (I-HDF) has been developed to improve patients' peripheral circulation by repeated intermittent infusion during HD treatment. SUMMARY: A prospective, multicenter, parallel group comparative trial examined the clinical effectiveness of I-HDF compared with predilution on-line HDF (pre-HDF), the most popular on-line HDF therapy in Japan...

We investigated the relationship between geriatric nutritional risk index (GNRI) and subpopulation lymphocyte counts (SLCs) in hemodialysis (HD) and peritoneal dialysis (PD) patients and evaluated whether they can be helpful in the diagnosis of malnutrition in these patients. We examined the GNRI and SLCs of 50 HD patients (mean: 55.8 ± 12.7 years; 28 men and 22 women) and 16 Continuous Ambulatory Peritoneal Dialysis (CAPD) patients (mean: 49.8 ± 14.5 years; 10 men and six women). The GNRI is calculated based on the serum albumin level, dry weight, and ideal body weight and uses the following equation: GNRI = [14...
