Abstract
BACKGROUND: The purpose of this study was to evaluate two commercial hemodialyzers (F100 and P21) through the clearance of identified and unidentified uremic solutes. METHODS: We investigated plasma samples from healthy and uremic subjects. RESULTS: We found three unidentified uremic solutes (P1, P2, and P3) after HPLC analysis of plasma samples. Then, we determined the clearance of four identified and the three unidentified uremic solutes in patients with F100 and P21. There was no significance between F100 and P21 in clearance of four identified uremic solutes. By contrast, the clearance of P1 and P2 with F100 was superior with the P21 (P < 0.05). CONCLUSION: Our data suggest that selection of a hemodialyzer based on the clearance of identified uremic solutes might not be sufficient. Application of external techniques to determine additional external factors (i.e., clearance of unidentified uremic solutes) can facilitate a better decision in the selection of the ideal hemodialyzer.
