OBSERVATIONAL STUDY
Desensitization Before Living Donor Kidney Transplantation in Highly HLA-Sensitized Patients: A Single-Center Study.
Transplantation Proceedings 2015 October
BACKGROUND: Renal transplantation in highly sensitized patients represents a major clinical challenge leading to long periods on the waiting list. When a living donor is available, the use of different strategies to desensitize recipients with preformed human leukocyte antigen antibodies can allow a successful transplantation.
METHODS: We performed a retrospective observational study including all living donor kidney transplantation (LDKT) with desensitization (DS) from 2008 to 2014 in our transplant unit. The rates of rejection and graft survival were evaluated. DS consisted of plasma exchange (PE), rituximab (RTX), and intravenous immunoglobulin (IVIG) induction with thymoglobulin and maintenance immunosuppression with tacrolimus, corticosteroids, and mycophenolate mofetil.
RESULTS: From 2008 to 2014, we performed 368 LDKT, with 31 receiving desensitization. Seven cases from a clinical trial were excluded. Demographic data and outcomes were recorded. All of the patients received RTX + PE + IVIG. DS was performed for positive complement-dependent cytotoxicity cross-match (4.2%), T-cell- and/or B-cell-positive flow cytometry cross-match (87.5%) and presence of donor-specific antibodies alone (8.3%). We identified 23 episodes of rejection in 12 patients (50%); 79% were antibody-mediated rejections (AMR). Graft failure was 12.5%, with a mean time to graft loss of 229 ± 203 days. Mean follow-up was 37 ± 27 months, and graft survival was 91% and 86% at 1 and 5 years, respectively.
CONCLUSIONS: Desensitization in LDKT appears to offer an acceptable option for highly sensitized patients. In our series, 41% presented an AMR and 12.5% showed transplant glomerulopathy in protocol and/or indication biopsies. However, short-term outcomes and graft survival were satisfactory.
