“…Previous studies have indicated that the presence of intraperitoneal fluid is insignificant when assessing volume status by whole body bioimpedance (8), in agreement with our findings. Nevertheless, some differences have been noted when performing segmental evaluation, in which the trunk and limbs can be assessed separately.…”

“…Nevertheless, the degree of discrepancy may vary between the type of analyzer and the absolute magnitude of difference may be small [20]. Conflicting results were obtained when bioimpedance spectroscopy (in the present study) and multi-frequency bioimpedance analysis were applied respectively [22]. More importantly, we have shown that change in body composition parameters (ovehydration and lean tissue mass) were significantly correlated with the degree of frailty as measured by the Frailty Score (Table 2).…”

Background/Aims: Previous studies showed that frailty is prevalent in both pre-dialysis and dialysis patients. However, the prevalence and prognostic implication of frailty in Chinese peritoneal dialysis (PD) patients remain unknown. Methods: We used a validated questionnaire to determine the Frailty Score of 193 unselected prevalent PD patients. All patients were then followed for 2 years for their need of hospitalization and mortality. Results: Amongst the 193 patients, 134 (69.4%) met the criteria of being frail. Frailty Score significantly correlated with Charlson's comorbidity score (r = 0.40, p < 0.0001), Malnutrition Inflammation Score (r = 0.59, p < 0.0001), and inversely with Subjective Global Assessment score (r = -0.44, p < 0.0001). Frailty was closely associated with the need of hospitalization. Patients with nil, mild, moderate, and severe frailty required 2.4 ± 6.0, 1.6 ± 1.6, 2.7 ± 2.5, 5.2 ± 4.8 hospital admissions per year, respectively (p < 0.0001), and they stayed in hospital for 6.4 ± 9.2, 5.3 ± 6.2, 10.0 ± 10.4, 12.9 ± 20.1 days per hospital admission, respectively (p < 0.0001). However, Frailty Score was not an independent predictor of patient or technique survival. Conclusions: Frailty is prevalent among Chinese PD patients. Frail PD patients have a high risk of requiring hospitalization and their hospital stay tends to be prolonged. Early identification may allow timely intervention to prevent adverse health outcomes in this group of patients.

“…In the present investigation, we have not only measured peritoneal glucose absorption, but also assessed body composition by bioimpedance method. This may suffer from methodologic errors, but is validated as a clinical tool to evaluate body composition in ESRD patients (19,20,42,43).…”

Background and objectives Insulin resistance has been associated with cardiovascular disease in peritoneal dialysis patients. Few studies have addressed the impact of fast transport status or dialysis prescription on insulin resistance. The aim of this study was to test whether insulin resistance is associated with obesity parameters, peritoneal transport rate, and glucose absorption.Design, setting, participants, & measurements Insulin resistance was evaluated with homeostasis model assessment method (HOMA-IR), additionally corrected by adiponectin (HOMA-AD). Enrolled patients were prevalent nondiabetics attending at Santo António Hospital Peritoneal Dialysis Unit, who were free of hospitalization or infectious events in the previous 3 months (51 patients aged 50.4615.9 years, 59% women). Leptin, adiponectin, insulin-like growth factor-binding protein 1 (IGFBP-1), and daily glucose absorption were also measured. Lean tissue index, fat tissue index (FTI), and relative fat mass (rel.FM) were assessed using multifrequency bioimpedance. Patients were categorized according to dialysate to plasma creatinine ratio at 4 hours, 3.86% peritoneal equilibration test, and obesity parameters.Results Obesity was present in 49% of patients according to rel.FM. HOMA-IR correlated better with FTI than with body mass index. Significant correlations were found in obese, but not in nonobese patients, between HOMA-IR and leptin, leptin/adiponectin ratio (LAR), and IGFBP-1. HOMA-IR correlated with HOMA-AD, but did not correlate with glucose absorption or transport rate. There were no significant differences in insulin resistance indices, glucose absorption, and body composition parameters between fast and nonfast transporters. A total of 18 patients (35.3%) who had insulin resistance presented with higher LAR and rel. FM (7.3 [12.3, interquartile range] versus 0.7 [1.4, interquartile range], P,0.001, and 39.4610.1% versus 27.2611.5%, P=0.002, respectively), lower IGFBP-1 (8.267.2 versus 21.0616.3 ng/ml, P=0.002), but similar glucose absorption and small-solute transport compared with patients without insulin resistance. FTI and LAR were independent correlates of HOMA-IR in multivariate analysis adjusted for glucose absorption and small-solute transport (r=0.82, P,0.001).Conclusions Insulin resistance in nondiabetic peritoneal dialysis patients is associated with obesity and LAR independent of glucose absorption and small-solute transport status. Fast transport status was not associated with higher likelihood of obesity or insulin resistance.

Influence of peritoneal dialysis solution on measurements of fluid status by bioimpedance spectroscopy

Abstract: The presence of peritoneal fluid in PD patients has a negligible influence on measurements of FO by BIS. The BIS measurements can be therefore conveniently and reliably done without emptying the peritoneal cavity; this may facilitate the use of BIS in this particular group of patients.
