Aluminum Removal with Hemodialysis, Hemofiltration and Charcoal Hemoperfusion in Uremic Patients after Desferrioxamine Infusion
NEPHRON(1989)
摘要
In order to compare the effectiveness of aluminum removal in uremic patients during extracorporeal treatment, 17 patients with endstage renal failure were given a desferrioxamine infusion of 40 mg/kg body weight after an ordinary dialysis treatment. Forty-eight hours later 7 patients were treated with hemodialysis, 6 with hemofiltration and 4 with a combination of hemodialysis and hemoperfusion. The clearance of aluminum was measured at different intervals. It was found that the aluminum clearance was 75 +/- 18 ml/min in hemofiltration compared to 30 +/- 10 ml/min in hemodialysis (p less than 0.001). A combination of hemodialysis and hemoperfusion with a charcoal column containing 100 g activated charcoal in series gave a total aluminum clearance of 56 +/- 11 ml/min. The total amount of aluminum in the ultrafiltrate after hemofiltration was found to be approximately 3 times as high (1,728 +/- 156 micrograms) as the total amount of aluminum in the hemodialysis water that had passed a single pass system during a 4-hour dialysis (576 +/- 104 micrograms). Our results indicate that hemofiltration or a combination of hemodialysis and hemoperfusion should be used to remove aluminum in patients with signs of severe aluminum accumulation such as encephalopathy or painful bone disease, because these methods are 2-3 times as effective as ordinary hemodialysis. In patients where aluminum has been accumulated but no severe symptoms occur hemodialysis gives a significant clearance of the aluminum desferrioxamine complex.
