Improved Fetal Hemoglobin With mTOR Inhibitor-Based Immunosuppression in a Kidney Transplant Recipient With Sickle Cell Disease

Fetal hemoglobin induction is a key point in the management of sickle cell disease (SCD). We report the case of a kidney transplant recipient with SCD who was treated with everolimus, a mammalian target of rapamycin inhibitor. At 10 months after initiating therapy, the patient's fetal hemoglobin level was dramatically increased (from 4.8% to 15%) and there was excellent tolerance to treatment.
