*Purpose: In HLA incompatible kidney transplantation, donor-specific HLA antibody often causes antibody-mediated rejection (AMR). To prevent AMR, we adopted a preoperative desensitization protocol including high-dose intravenous immunoglobulin (IVIG), plasmapheresis (PEX) and rituximab in sensitized recipients with positive flow cytometry crossmatch (FCXM).
*Methods: Patients who received the desensitization therapy with IVIG, PEX and rituximab for HLA incompatible living donor kidney transplantation (LDKT) since 2014 were included. We retrospectively investigated the patient background, clinical courses, DSA levels, and graft function.
*Results: Among the 11 HLA incompatible LDKT, AMR was revealed in 2 cases (18.2%) within 1 month after transplantation. There was no grafts loss during an average of 2.6-year follow-up. Average graft function was acceptable, with a serum creatinine level of 1.3 ± 0.7 mg/dL.
*Conclusions: The desensitization protocol including high-dose IVIG, PEX and rituximab is effective for achieving successful transplant outcomes in HLA incompatible LDKT with positive FCXM, which can spare aggressive treatments, such as C5 inhibitors, proteasome inhibitors, or imlifidase.
