Tacrolimus thrombotic microangiopathy

A 47-year-old multiparous Hispanic woman received a living-unrelated kidney transplant for end-stage renal disease secondary to polycystic kidney disease. On the day of transplantation she received intravenous daclizumab 1 mg/kg plus methylprednisolone 300 mg and mycophenolate mofetil 3 g/day, and on day 3 ciclosporin emulsion 4 mg/kg/day. On day 8 she developed thrombotic microangiopathy without evidence of rejection. Ciclosporin was withdrawn. Plasmapheresis with fresh frozen plasma was started. Daclizumab on day 14 was postponed for 24 hours and plasmapheresis was stopped to avoid clearance of daclizumab. Thereafter she was given tacrolimus, without recurrence of hemolysis.
