Abstract

The effects of dialyzer membrane material and concurrent angiotensin converting enzyme (ACE) inhibitor on plasma bradykinin levels during hemodialysis were investigated by administration of 3 successive hemodialyses using a PAN DX membrane dialyzer and another 3 using a polysulfone membrane dialyzer with the order of the 2 sequences randomized, for 6 patients receiving concurrent treatment with ACE inhibitor and 6 others receiving no ACE inhibitor. With the PAN DX membrane dialyzer the plasma bradykinin concentration obtained from the dialyzer outlet was significantly higher than that from the inlet at 10 min, but not at 5 min after initiation of dialysis, whereas no significant difference between inlet and outlet bradykinin concentrations was observed at either time with the polysulfone membrane dialyzer. No significant difference was observed between the changes in plasma bradykinin concentration in cases involving concurrent ACE inhibitor and that in cases receiving no ACE inhibitor. The results suggest that the PAN DX membrane dialyzer stimulates bradykinin production, but also that its release of bradykinin is delayed, possibly because of adsorption and modified release of bradykinin by the PAN DX membrane, and that ACE in...Continue Reading
