Plasmaperfusion for the treatment of intractable pruritus of cholestasis.

A patient with primary biliary cirrhosis and intractable pruritus was treated with plasmaperfusion of charcoal-coated glass beads on two occasions. The procedures were well tolerated and resulted in the removal of about 70% (494 mumol) of the estimated chenic acid pool. There was, in addition, pronounced amelioration of the pruritus which enabled the patient to sleep through the night without awakening because of itching. The pruritus, however, did not disappear and gradually returned to its preperfusion intensity by the end of the third week after perfusion.
