Abstract

Among the numeruos adverse side effects of tacrolimus (TAC), de novo thrombotic microangiopathy stands out as an infrecuente but severe complication. Renal dysfunction is the only alteration that should lead to suspicion of thrombotic microangiopathy, because the clinical features of intravascular hemolysis are not always found. The definitive diagnosis can usually be made with kidney biopsy. Patientes with TAC induced thrombotic microangiopathy usually promptly recover after treatment withdrawal or reduction in the dose of TAC and a short course of plasma therapy, but the risk of rejection increases. Switching from TAC to cyclosporine has also been tried with resolution of the hemolysis but thrombotic microangiopathy has been noted with both and this condition may later recur. We present a 29-year-old man who received a kidney-pancreas transplant for end-stage diabetic nephropathy. After initial induction with basiliximab, the immunosuppression consisted of prednisone, tacrolimus and mycophenolate mofetil. Twenty four days posttransplantation his renal function declined with a peak creatine level of 2.35 mg/dl. Laboratory studies showed thrombocytopenia and features of intravascular hemolysis. TAC associated hemolytic uremic s...Continue Reading
