常见的免疫抑制剂

Maintenance Therapy
Three-combined regimen --- Glucocorticosteroids (1~2 mg/kg/day) --- Calcineurin inhibitors (5 mg/ kg/ day) Ex : CsA, Tacrolimus (FK-506) --- Purine inhibitors Ex : AZA, MMF or added Sirolimus, Everolimus
Polyclonal vs. Monoclonal Ab

Maintenance Therapy
Cohort study, included 317 HT patients. (1) OKT3 7 days + CsA + MMF + S (2) OKT3 7 days + CsA + AZA + S (3) OKT3 10 days + CsA + MMF + S (4) OKT3 10 days + CsA + AZA + S (5) IL-2 antagonists + CsA + MMF + S (6) IL-2 antagonists + tacrolimus + MMF + S
Maintenance ~ MMF and AZA
MMF 3000 mg/ day
AZA 1.5~3 mg/kg/day
MMF vs. AZA
1. Reduction of mortality at 1 year (p=0.03)
2. Less requirement for treatment of rejection
therapy 2. High doses of CsA, Keep trough level :
250~350 μg/L in initial 6~12 months 3. Trough 150~250 ≒250~350 μg/L
