BODY COMPOSITION IN HEMODIALYSIS AND PERITONEAL DIALYSIS PATIENTS

Abstract

Bioimpedance analysis is a reliable technique for determining post dialysis target weight. Using this technique, we can understand body fluid status easier and conveniently. Moreover this technique can be used for check nutrition status and nutritional status of dialysis patients. We compared the body fluid status and nutrition status between hemodialysis (HD) patients and peritoneal dialysis (PD) patients by BCM (Body composition monitor) technique. We studied 48 (30 males and 18 females) PD patients, 21 (10 males and 11 females) HD patients. Body composition monitoring (BCM, Fesenitus Medical Care, Germany) was used as a tool for the analysis of bioimpedance. Extracellular water, Total body water, Intracellular water, Overhydration, E/I, Lean tissue mass, Fat Tissue mass was measured and those results were compared between two groups. HD patients were more hydrated than PD patients (61.9% vs. 35.4%) and nutritional status such as LTI was poorer than peritoneal dialysis patients (11.7±1.7 vs. 15.3±2.6). Although total body water is more abundant in peritoneal patients (29.4±5.5L vs. 35.9±6.2L), Extracellular water and intracellular water ratio was relatively higher in Hemodialysis patients (E/I 0.98±0.13 vs. 0.87±0.12). The nutrition status was better in PD patients by comparing the percent of lean tissue mass (LTM%) between two groups (LTM% 52.1±10.6% vs. 66.8±11.3). In conclusions, Hemodialysis patients were more hydrated with poorer nutrition status than peritoneal dialysis patients, but, due to the significant difference of age between two groups, further study should be required.
