Daily Versus Standard Hemodialysis: One Year Experience.

The aim of this study was to compare clinical and biological results in 4 standard hemodialyzed patients originally treated by three 4–5 h sessions per week and converted within one year to daily hemodialysis sessions of 2–2.5 h each 6 times per week. The modalities and the total weekly dialysis times remained the same. With daily hemodialysis, the blood pressure and left ventricular mass index decreased significantly (p < 0.01). A significant decrease in the urea time averaged deviation (TAD) (p < 0.005) and increase in the Kt/V index (p < 0.05) were observed. A gain in dry weight was shown with a rise in caloric intake from 33 ± 3.21 to 40.8 ± 6.35 kcal/kg/day (p < 0.05), and the normalized protein catabolic rate (nPCR) increased significantly (p < 0.0038). One patient who was receiving erythropoietin (EPO) for anemia could stop his treatment. No arteriovenous fistula complications were observed. Daily hemodialysis seems to be the method of choice to manage hypertension and left ventricular hypertrophy in uremic patients. The increase of the urea TAD to a value closer to that of the healthy kidney due to the increase of the frequency of dialysis is probably the main explanation for clinical improvement.
