    Abstract:
    Although initial experiences with FK 506 rescue therapy for acute hepatic allograft rejection have provided promising results, analysis of available data indicates that inferior results are obtained when FK 506 rescue therapy is initiated in the latter stages of rejection. Since its initial availability, we have applied an aggressive approach towards FK 506 rescue therapy based on early conversion and assiduous dosing. We have reviewed our experience with this approach in patients with refractory hepatic allograft rejection to provide an assessment of this approach. Sixteen patients were treated for corticosteroid and OKT3-resistant acute hepatic allograft rejection. Fourteen patients were treated for cellular rejection and 2 for humorally-mediated rejection. Median follow-up was 7.3 months posttransplant and 6.0 months post-initiation of FK 506 therapy. Median time to first rejection was 8 days and median time to FK 506 therapy was 29 days. Laboratory values at the time of initiation of FK 506 therapy included: mean serum bilirubin, 4.0 +/- 3.1 mg/dl and SGPT 136 +/- 105 U/l. Prior to FK 506 therapy, patients received an average of 35.5 +/- 19.1 mg/kg of bolus/taper corticosteroids (prednisone equivalent) and 11.25 +/- 4.8 days of OKT3 therapy. FK 506 therapy was successful in reversing all episodes of rejection. Median time to rejection reversal with FK 506 rescue therapy was 23 days (mean +/- SD, 27.6 +/- 16.7 days) in patients with cellular rejection. Time to rejection reversal was 26 and 28 days in the 2 patients with humoral rejection. Patient and graft survival at 6 months were 100%/100%, and 94%/94% at 12 months.(ABSTRACT TRUNCATED AT 250 WORDS)
