ELIMINATION OF FK-506 BY CONTINUOUS HEMODIAFILTRATION IN A LIVER-TRANSPLANT PATIENT

A liver transplant patient who developed renal failure postoperatively was treated using continuous hemodiafiltration (CHDF). Doses ranging from 0.01 to 0.06 mg/kg/day of FK-506 had been administered intravenou sly. FK-506 concentrations before and after the filter, and in the ult radiafiltrate were 45.3 +/- 2.9, 56.0 +/- 5.3, and 9.1 +/- 3.1 ng/ml ( mean,+/-S.D.), respectively. The filtration rate was 23.6 +/- 6.4%, an d extracted FK-506 amounted to 522.0 mu g (11.3% of administered dose) . A part of the FK-506 administered was eliminated through the filter during CHDF.
