Sirolimus and calcineurin inhibitors such as tacrolimus and cyclosporine have been shown in renal and lung transplant recipients to cause hemolytic anemia, thrombotic thrombocytopenic purpura, and atypical hemolytic uremic syndrome [15] [16] [17] . While this etiology is more often identified as a drug-related phenomenon, particularly due to the immunosuppressants required to prevent organ rejection (see next section), there have been multiple case reports associating CMV infection as a trigger of TMA in the posttransplant setting [53, 54] . When this is identified, numerous case studies in multiple different organ systems (lung, liver, kidney solid organ transplant) have reported that changing from one CI to another (tacrolimus to cyclosporine or vice versa) or to another class of medication such as sirolimus or mycophenolate mofetil can prevent further episodes of TMA from occurring [61] [62] [63] [64] .	./cache/cord-016478-gpl0zbvd.txt	./txt/cord-016478-gpl0zbvd.txt
