Effects of Serial Resin Hemoperfusion in Fulminant Hepatic Failure

Abstract

Resin hemoperfusion using an albumin coated Amberlite XAD-7 column was performed in 19 patients in coma due to fulminant hepatic failure. The procedure was clinically well tolerated, with good blood compatibility, platelet and white cell levels being 97.3 ± SE 3.2% and 105 ± 3.8% of the respective initial values after four hours hemoperfusion. No significant changes were observed in β-thromboglobulin, screen filtration pressure, plasma electrolytes, calcium, protein or albumin. The total plasma bilirubin fell by a mean of 24 μmol/l, with a reduction in 21 of the 25 perfusions studied of up to 104 μmol/l during perfusion. Mean plasma levels of total bile acids were 137 ± 19 μmol/l and 115 ± 16 μmol/l respectively before and after four hours hemoperfusion. The amount of bile acids recovered by elution of the resin column was over three times greater than that apparent from the change in plasma levels. Column chromatography on Sephadex G-25 of material eluted from the resin column showed various peaks to be removed, including substances in the middle molecular weight range (1000-5000 daltons). Of the patients treated, eight (42%) survived to leave hospital.
