Thrombotic microangiopathy (TMA) is a well-recognized complication of solid organ transplantation. Both calcineurin inhibitors cyclosporine [1] and tacrolimus [2] have been associated with TMA. Treatment strategies for TMA have included plasmapheresis [1,2], calcineurin inhibitor dose reduction [1,2], calcineurin inhibitor withdrawal [1,2], and conversion from one calcineurin inhibitor to the other [3]. However, calcineurin inhibitor dose reduction or discontinuation increases the risk of acute allograft rejection and recurrent TMA has been described in patients that were converted from cyclosporine to tacrolimus [4,5]. We present two cases of biopsy-proven transplant-associated TMA that were successfully treated by discontinuation of tacrolimus followed by the use of sirolimus, mycophenolate mofetil (MMF) and prednisone for the prevention of allograft rejection.
