Biochemical assessment and clinical evaluation of a bilirubin adsorbent column (BR-350) in critically ill patients with intractable jaundice.

We investigated the efficacy of an anion-exchange adsorbent column (ASAHI BR-350, DIAMED) for removal of bilirubin and bile acids in five patients with intractable jaundice of various origin. Four litres of plasma were separated by membrane plasma separation (Plasmaflow OP-05) at a rate of 22.5 ml/min. The plasma was then perfused through an anion exchange adsorbent and returned to the venous blood line of the plasma separation. In some of the patients this procedure was combined with regular hemodialysis treatment. The concentration of total bilirubin was cut by 31 to 60%; total bile acids were reduced by 20 to 74%. Three patients recovered and had a favourable outcome. Two patients died despite the bilirubin adsorption treatment. The effects of the adsorbent column on specific blood parameters, including the coagulation system, were measured. Our data suggest that bilirubin adsorption should be examined further as a treatment for critically ill patients with intractable jaundice.
