“…We did not find any association between higher scores and loss of muscle mass. We measured muscle mass by bioimpedance, 32 and previous studies have reported differences using bioimpedance devices in HD patients, 7 , 33 and even though we allowed for reequilibration following the dialysis session, 34 further studies using DXA 35 or isotopic methods may be required to confirm our results.…”

“…As HD patient survival is reduced in cases of both muscle weakness and wasting, rapid screening tests are useful to detect muscle weakness and wasting at an early stage. Although dual‐energy x‐ray absorptiometry (DXA) and bioimpedance methods can be used to assess lean body mass (LBM), 4 , 5 these methods may overestimate LBM in patients who are overhydrated 6 , 7 . As such, many kidney dialysis centers use handgrip strength (HGS) as a functional assessment of muscle weakness, 8 which can be readily tested when patients attend for dialysis sessions or in the outpatient clinic.…”

Effect of Self‐Reported Distress Thermometer Score on the Maximal Handgrip and Pinch Strength Measurements in Hemodialysis Patients

Paradoxically higher self-reported DT scores were associated with younger age and lean body mass. As such, younger healthier, rather than more comorbid, patients may have greater expectations for their health and therefore report more distress. We found no association between DT scores and HGS, and as such, although HGS is a voluntary test, it appears to be a robust test independent of patient stresses. However, PS was lower in patients with higher DT scores, and as such, greater care may be required in interpreting these measurements.

“…In addition, the noninvasive nature of bioimpedance makes it particularly well suited for measuring longitudinal changes. Notably, BIS techniques have recently shown promise in assessing body composition and mortality risk in people on dialysis 81 and in managing fluid status in dialysis 88 – 93 as well as surgery 92 and critically illness 91 …”

Assessment of body composition, both at single time points and longitudinally, is particularly important in clinical nutrition practice. It provides a means for the clinician to characterize nutrition status at a single time point, aiding in the identification and diagnosis of malnutrition, and to monitor changes over time by providing real-time information on the adequacy of nutrition interventions. Objective body composition measurement tools are available clinically but are often underused in nutrition care, particularly in the United States. This is, in part, due to a number of factors concerning their use in a clinical context: cost and accessibility of equipment, as well as interpretability of the results. This article focuses on the factors influencing interpretation of results in a clinical setting. Body composition assessment, regardless of the method, is inherently limited by its indirect nature. Therefore, an understanding of the strengths and limitations of any method is essential for meaningful interpretation of its results. This review provides an overview of body composition technologies available clinically (computed tomography, dual-energy x-ray absorptiometry, bioimpedance, ultrasound) and discusses the strengths and limitations of each device.

“…As muscle contains more water than fat, this leads to an overestimation of lean body mass pre dialysis, with a reduction in lean body mass post dialysis [24] . More recently, a three-compartmental body composition model has been proposed, dividing the body into adipose tissues, normally hydrated lean tissue and excess water, but even this model still overestimates lean body mass pre dialysis [25] . We measured bioimpedance post dialysis after allowing for a redistribution of fluid to overcome these effects on bioimpedance measurements.…”

Background: Muscle weakness is a risk factor for mortality in haemodialysis (HD) patients; we wished to determine whether measuring the composition of the arm with bioimpedance was associated with arm muscle strength. Methods: We measured pinch strength (PS) and hand grip strength (HGS) in 250 adult HD patients with corresponding post-dialysis multifrequency bioelectrical assessments with segmental body analysis. Results: Mean age 64.0 ± 15.6, 66% male and 45.6% diabetic. The maximum HGS in the dominant or non-fistula arm was 18.9 ± 9.2 kg and PS 4.09 ± 1.96 kg respectively, with a correlation of r = 0.80, p < 0.001. HGS was associated with body cell mass (β 0.37, p < 0.001) and PS with appendicular muscle mass (β 0.06, p < 0.001). Both HGS and PS were independently associated with the ratio of extracellular water (ECW) to total body water (TBW); β -139.5, p = 0.024, β -44.8, p < 0.001 in the arm. The presence of an arterio-venous fistula increased the ECW/TBW ratio in the arm from 0.383 ± 0.009 to 0.390 ± 0.012, p < 0.05. Conclusion: Muscle strength measured by HGS and PS was associated with both markers of whole body and segmental body composition within the arm, particularly ECW/TBW. Bioimpedance measurements and assessment of muscle strength should be measured in the non-fistula arm.

Changes in Intracellular Water Following Hemodialysis Treatment Lead to Changes in Estimates of Lean Tissue Using Bioimpedance Spectroscopy

Abstract: In clinical practice, predialysis bioimpedance measurements are more convenient. However, for more reliable and reproducible assessments of nutrition status, we suggest that measurements of body composition should be made when patients are not overhydrated.
