Single-shot antithymocyte globuline and daclizumab induction in simultaneous pancreas and kidney transplant recipient: three-year results.

Since 1996, preoperative single-shot dose antithymocyte globuline (ATG) with prednisolone (PRD), mycophenolate mofetile (MMF), and tacrolimus (TAC) is the favorite induction therapy in our center. In a series of 25 first simultaneous pancreas and kidney transplant (SPK) recipients, 5 doses of daclizumab were administered in addition to standard induction. Here we present our 3-year experience. Immunosuppression was started prior to reperfusion consisting of daclizumab (1 mg/kg body weight [bw]), ATG (4-6 mg/kg bw) and 250 mg PRD. After surgery, PRD was reduced gradually, TAC trough levels were between 8-15 ng/mL, MMF was given twice daily (2-3 g/d) as well as 4 further doses dacilzumab every 14 days. After 3 years, patient, pancreas, and kidney graft survival rates are 100%, 84%, and 92%, respectively. Four pancreas grafts were lost (chronic allograft dysfunction, n = 2; recurrent abdominal infection, n = 1; acute rejection [AR] without treatment, n = 1). Both patients suffering from severe infection and untreated AR lost their kidney graft too. During the first 3 months after SPK, 3 AR episodes were observed in 2 patients (8%). After a 3-year period, 8 AR episodes occurred in 7 recipients (28%). AR was treated using PRD (n = 5) or ATG (n = 1). In 1 case, immunosuppression was switched from TAC to sirolimus successfully. Overall, 8 AR episodes occurred in 7 patients (28%) during the first 3 years after SPK. One severe infection led to graft lost 13 months after SPK. In this series, the combination of ATG and daclizumab prevented AR episodes, successfully providing considerable 3-year survival rates.
