Objective We aimed to evaluate the agreement between the resting energy expenditure (REE) obtained by indirect calorimetry and eight prediction equations in adult patients with renal transplantation and a newly developed REE prediction equation for use in patients with renal transplantation in the clinic. Methods A total of 51 patients (30 males and 21 females) were involved in the study. The REE was measured by indirect calorimetry and compared with the previous prediction equations. The agreement was assessed by the …

Serum carnitine is decreased in hemodialysis patients, which induces muscle atrophy. Thus, we examined the different effects of l‐carnitine and exercise on exercise activity and muscle status in hemodialysis patients. Twenty patients were divided into l‐carnitine and cycle ergometer groups and were followed for 3 months. Muscle and fat mass, physical activities, and muscle status were evaluated by an impedance, physical function test, and magnetic resonance imaging, respectively. The l‐carnitine significantly increased muscle mass (P …

Background/Aims: The purpose of this study was to evaluate the clinical usefulness and relevance of bioelectrical impedance analysis (BIA) for assessing the fluid and nutritional status in peritoneal dialysis (PD) patients. Methods: Statistical analyses between various measures of fluid and nutritional status were performed in 106 cases of 64 patients. Results: Extracellular fluid/total body water (ECF/TBW) was correlated with systolic blood pressure, extremity edema, and antihypertensive medications (p= 0.042, p< 0.001, and p= 0.029 …

Objective (s) To explore the validity of using bioelectrical impedance analysis (BIA)-derived 50 kHz phase angle (PhA) in predicting protein–energy wasting (PEW) in Chinese maintenance hemodialysis (MHD) patients. Design and Methods The design was a cross-sectional study. A total of 173 of MHD patients and 173 healthy adults were enrolled in the study. The prevalence of PEW in patients was performed by the International Society of Renal Nutrition and Metabolism criteria. The PhA, body cell mass, fat mass, body fat …

Kidney transplantation and accompanying medical conditions may result in changes in body composition. Such changes have been evaluated in Caucasian recipients, but not in Asian recipients. Herein, we conducted a study on Asian recipients because Asians have a different body composition from Caucasians. A total of 50 Asian recipients was enrolled as a prospective cohort. Using bioelectrical impedance analysis, body composition (muscle and fat mass) was assessed after 2 weeks (baseline), and at 1, 3, 6, 9, and 12 months following …

Introduction Sarcopenia is an involuntary decline in skeletal muscle mass, strength, and function that normally proceed with aging but may develop faster under some chronic disease conditions. In this study, we compared the physical activity between sarcopenia and non-sarcopenia subgroups in kidney transplant recipients. Methods Fifty-eight recipients (42 males and 16 females) were enrolled in this study. Mean age of the recipients was 46.6±12.7 years. Mean duration of dialysis was 2.8±4.0 years. Diagnostic criteria for …

Chronic kidney disease (CKD) is frequently complicated with hyponatremia, probably because of fluid overload or diuretic usage. Hyponatremia in CKD population is associated with increased mortality, but the effect on renal outcome was unknown. We investigated whether hyponatremia is associated with fluid status and is a prognostic indicator for adverse outcomes in a CKD cohort of 4,766 patients with 1,009 diuretic users. We found that diuretic users had worse clinical outcomes compared with diuretic non-users. Hyponatremia …

Bioimpedance can be used to measure extracellular water (ECW) and total body water in hemodialysis (HD) patients and estimate ECW excess. However, ECW excess potentially includes both an increase in the plasma volume and also the extravascular volume. Overestimating the amount of fluid to be removed during HD risks intra‐dialytic hypotension. We wished to determine the association between estimates of ECW excess comparing several different equations using bioimpedance, brain N‐terminal pro‐brain natriuretic …

Excess extracellular volume is a major clinical problem in patients with chronic kidney disease (CKD). However, whether the extracellular volume status is associated with disease progression is unclear. We investigated the association between the extracellular volume status and renal outcomes. We performed a retrospective cohort study of 149 patients with CKD who underwent bioelectrical impedance analysis (BIA) from 2005 to 2009. Patients were categorized according to tertiles of extracellular volume status. The extracellular …

Purpose To determine whether vigorous and moderate physical activity volumes are associated with skeletal muscle loss and chronic kidney disease–mineral and bone disorder (CKD-MBD) in hemodialysis (HD) patients. Methods Skeletal muscle index (SMI) was measured using a bioelectrical impedance plethysmograph, and grip strength using a hand dynamometer, in 32 HD patients and 16 healthy controls. In HD patients, bone density was measured using digital image processing, and serum bone metabolism markers were …
