Long-term outcome of sirolimus rescue in kidney-pancreas transplantation.
The aim of this study was to evaluate long-term outcome of sirolimus (SRL) rescue in kidney-pancreas transplantation (KPTx). We reviewed 112 KPTx performed at our institution from 12/3/95 to 6/27/02. All patients received antibody (Ab) induction, tacrolimus (TAC), mycophenolate mofetil (MMF), and steroids. Thirty-five patients (31%) had SRL substituted for MMF for the following indications: (1) acute rejection (AR) of kidney or pancreas despite adequate TAC levels; (2) intolerance of full-dose MMF; (3) rising creatinine; and (4) TAC-induced hyperglycemia. Target SRL and TAC levels were 10 ng/mL and 5 ng/mL, respectively. Mean follow-up was 3 +/- 2 years overall and 1.2 +/- 0.5 years after SRL rescue. No patients died. One- and 3-year actuarial kidney and pancreas graft survival was 97%, 97%, and 95%, 90%, respectively. Of 10 patients switched to SRL for AR, 1 kidney failed from Ab-resistant AR, 1 kidney developed borderline AR, and the other 8 remain AR-free. Seven other patients developed AR despite therapeutic SRL levels; of these, 6 (86%) had mean TAC levels of <4.5 in the month preceding AR. Mean creatinine overall and for the rising creatinine group remained stable. All patients switched to SRL for TAC-induced hyperglycemia or MMF intolerance demonstrated biochemical or clinical improvement. Sirolimus-related infection or other serious adverse events (SAE) were uncommon. In conclusion, KPTx recipients can be safely switched to SRL with long-term stabilization of renal function, excellent graft and patient survival, and no increase in SAE. A minimum TAC level of 4.5 ng/mL may be necessary to prevent late AR.
