COMPARISON OF REDUCTION RATIO OF INDOXYL SULFATE BETWEEN COMBINATION OF HIGH CUT-OFF MEMBRANE HEMODIALYSIS WITH HEMOPERFUSION AND HIGH-EFFICIENCY ONLINE-HEMODIAFILTRATION WITH HIGH FLUX MEMBRANE; AN OPEN-LABELLED RANDOMIZED CROSS-OVER CONTROL TRIAL
Abstract:
Objective: We proposed a new HD modality which can be performed in any HD centers with standard HD machine by using high cut-off (HCO) dialyzer in combination with hemoperfusion (HP) and compare with OL-HDF Method: This was a cross-over randomized control trial. Ten chronic hemodialysis patients were randomized to consecutively undergo dialysis with either new HD modality (HCO HD with HP) or OL-HDF before cross-over to the other modality for 8-week each period. The efficacy including percentage reduction after dialysis of IS, β2 microglobulin (β2m) and urea were assessed. Patient safety and dialysate albumin loss were monitored. IS was measured by high performance liquid chromatography. Result: The percentage reduction of IS were comparable between HCO HD with HP and OL-HDF (52.0±11.7 vs. 56.3±7.5 %, p=0.14). The percentage reduction of β2m did not differ (83.7±4.9 vs. 84.0±4.3 %, p=0.37). Two techniques provided adequate small solute removal. Although the dialysate albumin loss was significantly higher in HCO HD with HP than OL-HDF (4.2±2.4 vs. 0.5±0.8 g/session; P=0.004), there were no significant long-term changes in serum albumin levels of both modalities. Conclusion: Standard HD using HCO dialyzer with HP, which could be performed in any HD centers, can effectively remove IS, β2m, and small toxin in comparable with OL-HDF and could replace OL-HDF where it is unavailable.
