Abstract

PURPOSE
During hemodialysis, various methods are used to evaluate adequate water removal; however, few of them are currently clinically applicable. To evaluate the differences of body fluid changes, we have compared changes of ICW (intracellular water) and ECW (extracellular water) before and after hemodialysis in diabetic and non-diabetic patients with MF-BIA. Also various factors influencing in this transcellular body fluid shift were evaluated.
METHODS
TBW (total body water), ICW, ECW were measured before and after hemodialysis by using MF-BIA in 85 stable maintenance hemodialysis patients in a university hospital. Among these patients, 30 patients (mean age 55.6+/-12.4 year-old, average dialysis duration 26 months) were diabetic, while 55 patients (mean age 47.1+/-13.0 year-old, average dialysis duration 69 months) were non-diabetic.
RESULTS
ECW/TBW in diabetic and non-diabetic patients were 0.338+/-0.02, 0.334+/-0.02, respectively. There was no significant difference between two groups. There were also no significant differences in the sex, age, duration of dialysis, BMI, hemoglobin, total protein, osmolarity of ICW loss/TBW removal. But there was a significant positive correlation between the increase in ultrafiltration volume (UFV:%) and ICW loss in diabetic patients (R=0.51, p=0.019); however, such correlation was not observed in non-diabetic patients.
CONCLUSION
We found that ICW of diabetic patients moved to extracellular spaces even before achieving appropriate dry body weight or less amount of fluid was removed compared to non-diabetic patients. This finding might imply diabetic ESRD patient has relatively low cellular membrane integrity and oncotic pressure maintenance ability to physical transmembrane pressure.
