“…A portable whole‐body bioimpedance spectroscopy device (Body Composition Monitor, Fresenius Medical Care GmbH, Bad Homburg, Germany) was used for the assessment of hydration state and body composition Patients with amputations, cardiac pacemakers or defibrillators were excluded from measurement. BIS measurements were performed in a standardized manner, as previously reported, as part of the established routine of clinical care. During measurements, PD patients were placed in a supine position, and their peritoneal cavities were filled with PD fluid.…”

“…Precise evaluation of fluid overload is important for appropriate management of the PD prescription and diuretic and antihypertensive drug dosing (15). Volume overload has deleterious cardiovascular consequences and, even if clinically undetectable, has been shown to adversely affect prognosis in PD patients (16)(17)(18).…”

Intraperitoneal Fluid Overestimates Hydration Status Assessment by Bioimpedance Spectroscopy

♦ Background: Bioimpedance spectroscopy (BIS) is a valuable tool to assess nutrition and volume status in peritoneal dialysis (PD) patients. However, data about the influence of intraperitoneal fluid on body composition measures are conflicting, and there is no clear consensus about whether the abdomen should be drained before the procedure. We designed a comparison study to detect the influence of intra-abdominal fluid on BIS results.

“…Nevertheless, the utility of bioimpedance technique in clinical practice remains controversial. Although some authors recommend that routine application of this technique is useful for objective evaluation of fluid status 33 and optimization of BP control, 34,35 others suggest that it adds no additional benefit in terms of cardiovascular outcome, especially in non-anuric patients. 36,37 Therefore, the optimal way to use bioimpedance technique has not been elucidated yet.…”

Background: This 6-month prospective longitudinal study investigates the association between hydration status changes using bioimpedance spectroscopy (BIS) and systolic blood pressure (SBP), pulse pressure (PP), and serum albumin (sAlb) changes in children on peritoneal dialysis (PD). Methods: Thirteen patients (median age: 12.58 years) were enrolled. Normal hydration, moderate hydration, severe overhydration, and dehydration were defined as −7% ≤ relative overhydration (Re-OH) < +7%, +7% ≤ Re-OH < +15%, Re-OH ≥ +15%, and Re-OH < −7%, respectively. Automated office blood pressure z-score, sAlb, and weight z-score were recorded. Results: Fifty-two Re-OH measurements were recorded: three in five, four in five, five in two, and seven in one patient, respectively. SBP was higher and sAlb lower in cases with severe overhydration (9 readings) ( p < 0.001, p < 0.001), but distribution of these parameters did not differ between normal hydration/dehydration (28 readings) and moderate overhydration (15 readings) cases. In patients with hydration status change, SBP and PP were higher while sAlb lower in cases with higher hydration status level ( p = 0.026, p = 0.05, and p = 0.109, respectively). In all patients, visit-to-visit SBP, PP, and sAlb changes were correlated to Re-OH changes ( rs = 0.693, p < 0.001; rs = 0.643, p < 0.001; rs = −0.444, p = 0.008, respectively) but not to weight changes ( rs = 0.052, p = 0.754; rs = 0.034, p = 0.838; rs = −0.156, p = 0.378, respectively). Visit-to-visit Re-OH changes, which were >+4% or <−4%, were linearly correlated to SBP ( r = 0.858, p < 0.001), PP ( r = 0.757, p < 0.001), and sAlb ( r = −0.699, p = 0.002) changes. Conclusion: In children on PD, longitudinal Re-OH changes are superior to weight changes in assessing volume-dependent variations of SBP, PP, and sAlb. Routine BIS application, rather than single BIS measurements, seems useful in the intra-patient monitoring of hydration status.
