Mycophenolate mofetil decreases rejection in simultaneous pancreas-kidney transplantation when combined with tacrolimus or cyclosporine
Abstract
BACKGROUND: Historically, the acute rejection rates in simultaneous pancreas-kidney (SPK) recipients have been extremely high (50-80%), with many second and third rejection episodes despite the use of quadruple immunosuppression (antibody induction and cyclosporine [CsA]-azathioprine [AZA]-based maintenance immunosuppression). Although this acute rejection has rarely led to graft loss, it has been a great cause of morbidity and of significantly increased cost. In an attempt to decrease the acute rejection rate and related morbidity in SPK transplant recipients, we compared two "state-of-the-art" immunosuppression regimens in a prospective, randomized, single-center study.
METHODS: Patients who received SPK transplants were randomized to receive either tacrolimus (TAC) and mycophenolate mofetil (MMF, n=18) or CsA (Neoral formulation) and MMF (n=18). All patients received OKT3 induction and prednisone, which was tapered to 5 mg/day by 6 months after transplantation. All rejection episodes were biopsy proven. In addition, metabolic control (HgbA1C, hypertension, serum cholesterol), drug toxicity, and infection also were measured. Data were compared with that of a historical group (n=18) who received conventional CsA (Sandimmune formulation) and AZA-based immunosuppression.
RESULTS: The incidence of biopsy-proven acute rejection was 11% in both the TAC-MMF and CsA-MMF groups with only two patients in each group experiencing a rejection episode. This rejection rate was…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 18 participants or records.
