Nutrition Status And Body Composition In Hemodialysis Versus Peritoneal Dialysis Patients

Purpuse: It has been postulated that fluid overload and lipid metabolic derangement is more common in peritoneal dialysis (PD) patients than in hemodialysis (HD) patients. The purpose of this study was to evaluate the differences in body composition in HD and PD patients.Methods: We compared whole body composition using bioimpedence analysis (BIA) in 14 hemodialysis patients and 14 peritoneal dialysis patients. BIA was performed at 1, 3, 6, and 12 months after initiation of HD or PDResults: Compared with HD patients, PD patients had a higher ratio of extracellular fluid/total body fluid at 12 months (0.39 vs 0.34, p<0.05) and a lower level of serum albumin (3.6g/dL vs. 3.9g/dL, p
