It is attribut-ed to recombinant human erythropoietin (rHuEPO) administration. Although immunosuppression is the main-stay therapy, its effectiveness varies from 30% to 70%. PRCA in ESKD has been reported to improve following kidney transplantation. Case Report: A 46-year-old woman with ESKD secondary to lupus nephritis was treated for uremia at our center. She developed severe anemia. Bone marrow aspiration and biopsy revealed a reduction of erythroid precursors, consistent with PRCA. Because she had no sibling’s blood group matched with her, ABO-incompatible kidney transplantation was an option for treatment. She underwent a desensitization protocol consisting of rituximab 375 mg/m2, tacrolimus, mycophenolate mofetil, and prednisolone 4 weeks before surgery, in addition to 3 sessions of double-filtration plasmapheresis (DFPP) every other day followed by intravenous immunoglobulin (IVIG) and 1 session of specific immunoadsorption (Glycosorb® B column) at pre-transplant day-1. She also received low-dose rabbit anti-thymocyte globulin (rATG) (Thymoglobulin®) (total 2.0 mg/kg). Maintenance therapy included tacrolimus, mycophenolate mofetil, and prednisolone. Allograft function normalized a few days after transplantation and her Hb gradually increased. Conclusions: We report a rare case of PRCA in a patient with ESKD undergoing ABO-incompatible kidney transplantation. The outcome was satisfactory, with complete correction of anemia and kidney function.MedicineArticleSCOPUS10.12659/ajcr.9354512-s2.0-851340160221941592335842751
