Abstract
Bioimpedance analysis has been widely used to estimate a hydration state, lean and fat mass in haemodialysis patients. The aim of our study was to investigate the validity and usefulness of bioimpedance analysis in routine dialysis practice. Last two years we used the body composition monitoring (BCM, Fresenius Medical Care), method based on whole body multifrequency bioimpedance spectroscopy (BIS), compared with traditional clinical data. For BIS data verification, hydration status of 32 stable HD patients with dialysis vintage more than 3 years and clinically well established dry weight were studied. Only in three cases BIS data seems underestimated in serial measurements. Next step, 28 healthy subjects and 116 dialysis patients were studied. Total body water and extracellular volume (ECV) were significantly higher in dialysis group (P<0.01), and there was not any difference in intracellular volume (ICV). Mean AP was similar in patients with moderate (<15%) and massive (>15%) relative overhydration (RO = overhydration / ECV), at the same time, average number of antihypertensive medications was significantly higher in more overhydrated patients (3.1 vs 1.2). In clinical practice RO is more convenient indicator as compared to standard overhydration volume /dry weight ratio. Mutual application of the BIS and blood volume monitoring allows more rapid and safe dry weight achievement. BIS was useful tool for hydration status monitoring in routine haemodialysis practice, and further work need to be done to clarify BIS validity for nutritional status estimation.
