Accuracy and precision of segmental bioimpedance technique to assess peridialytic changes in total body water
Nephrology | TBW | A Topping et al. | 2017 | USA | Nephrology Dialysis Transplantation
Background Fluid volume assessment remains a challenge in clinical nephrology. Bioimpedance has gained widespread popularity and has the potential to guide fluid management in various aspects. Bioimpedance allows the assessment of total body water (TBW) thus providing insight into fluid status. We aimed to investigate the accuracy and precision of TBW measurements with a segmental multifrequency bioimpedance device (InBody 770; InBody USA, Cerritos, CA, USA) by comparing the peridialytic changes in …
Negative dialysate to sodium gradient does not lead to intracellular volume expansion post hemodialysis
Nephrology | ECW, ICW | Davenport A | 2010 | UK | International journal of Artificial Organs
Introduction Intradialytic hypotension remains the most common complication of routine outpatient hemodialysis treatments. There is debate as to the optimum dialysate sodium concentration, with hypotonic dialysates potentially causing intracellular swelling and hypertonic ones intracellular dehydration. Methods Multi-frequency bioimpedance was used to assess extracellular and intracellular fluid volumes in 53 adult hemodialysis patients. Dialysate sodium was checked by ion electrophoresis. Results The mean decrease in …
Extracellular volume expansion, measured by multifrequency bioimpedance, does not help preserve residual renal function in peri
Nephrology | ECW/TBW | Keran McCafferty, Davenport A et al. | 2013 | UK | Kidney International
Residual renal function is a major survival determinant for peritoneal dialysis patients. Hypovolemia can cause acute kidney injury and loss of residual renal function, and it has been suggested that patients receiving peritoneal dialysis should preferably be maintained hypervolemic to preserve residual renal function. Here we determined whether hydration status predicted long-term changes in residual renal function. Changes in residual renal function and extracellular water (ECW) to total body water (TBW) measured by …
Protocolized exercise improves frailty parameters and lower extremity impairment: a promising prehabilitation strategy for kidn
Nephrology | FMI, SMI, ASMI | C. Lorenz et al. | 2020 | USA | Clin Transplant
Background Frailty and decreased functional status are risk factors for adverse kidney transplant (KT) outcomes. Our objective was to examine the efficacy of an exercise intervention on frailty and decreased functional status in a cohort of patients with advanced chronic kidney disease (CKD). Methods We conducted a prospective study involving 21 adults with≥ stage 4 CKD who were (a) frail or pre‐frail by Fried phenotype and/or (b) had lower extremity impairment [short physical performance battery score≤ 10]. The intervention …
Comparisons of amino acids, body constituents and antioxidative response between long‐time HD and normal HD
Nephrology | BW, BMI, TBW, ECW, SMM, Protein, Mineral | Torigoe A et al. | 2016 | Japan | Hemodialysis International
Introduction Oxidative stress is one of the main mediators of progression of chronic kidney diseases (CKD). Nuclear factor E2‐related factor 2 (Nrf2) is the transcription factor of antioxidant and detoxifying enzymes and related proteins which play an important role in cellular defense. Long‐time hemodialysis (HD) therapy (8 hours) has been considered to be more beneficial compared to normal HD therapy (4 hours). We investigated oxidative response related to Nrf2 in peripheral blood mononuclear cells (PBMCs) of long‐time HD …
Association Between Home Blood Pressure and Body Composition by Bioimpedance Monitoring in Patients Undergoing Peritoneal Dialy
Nephrology | TBW, ECW/TBW, SLM, PBF | Kurasawa N et al. | 2015 | Japan | Advances in Peritoneal Dialysis
Home blood pressure (HBP) is an independent predictor of cardiovascular and renal function. However, no particular guidelines have been established for optimal HBP in peritoneal dialysis (PD) patients. Bioelectrical impedance analysis (BIA) is a beneficial tool for determining body composition. In the present study, we used BIA to determine body composition parameters that might play a role in the regulation of HBP in PD patients, and we compared HBP with office blood pressure (BP). Our study enrolled 15 patients (11 men …
N-terminal proBNP—marker of cardiac dysfunction, fluid overload, or malnutrition in hemodialysis patients?
Nephrology | ECW, ICW | John Booth, Jennifer Pinney, Davenport A | 2010 | UK | Clinical Journal of the American Society of Nephrology
Background and objectives: N-terminal probrain type natriuretic peptide (NTproBNP) has been proven to be a valuable biomarker for predicting cardiac events and mortality in the hemodialysis population. However recent reports have suggested that NTproBNP is a marker of volume overload rather than one of cardiac dysfunction. Therefore this study investigated the effect of fluid volume status on NTproBNP. Design, setting, participants, & measurements: Volume status was determined pre-and postdialysis in 72 stable …
Baseline higher peritoneal transport had been associated with worse nutritional status of incident continuous ambulatory perito
Nephrology | ECW, ICW, ECW/TBW, FFM, SMM, PBF, Phase angle | Liu Y et al. | 2015 | China | British Journal of Nutrition
The aim of the present study was to investigate the relationship between baseline peritoneal transport types and nutritional status in Chinese continuous ambulatory peritoneal dialysis (CAPD) patients. In the present single-centre, prospective study, incident CAPD patients were included from 15 April 2010 to 31 December 2011 and were followed up for 12 months. According to the results of baseline peritoneal equilibration test, patients were divided into lower peritoneal transport group (lower transporters) and higher peritoneal …
