Abstract

Introduction The number of end-stage renal disease (ESRD) patients with preformed antibodies waiting for a kidney transplant has been increasing lately. We conducted a nationwide study on the outcomes of kidney transplantation after desensitization in Korea. Methods: Six transplant centers have run desensitization programs. The patients who underwent living donor kidney transplantation after desensitization from 2002 to 2010 were retrospectively analyzed. Results: A total of 86 cases were enrolled. Thirty-five of these were cases of re-transplantation (40.7 %). Indications of desensitization were positive complement-dependent cytotoxicity (CDC) cross-match responses (CDC +, 36.0 %), positive flow-cytometric cross-match responses (FCX?, 54.7 %), and positive donor-specific antibodies (DSA?, 8.1 %). The desensitization protocols used pre-transplant plasmapheresis (95.3 %), intravenous immunoglobulin (62.8 %), and rituximab (67.4 %). Acute rejection occurred in 18 patients (20.9 %), graft failure occurred in 4 patients, and the 3-year graft survival rate was 93.8 %. The presence of DSA increased the acute rejection rate (P = 0.015) and decreased the 1-year post-transplant estimated glomerular filtration rate (P = 0.006). Although rejection-free survival rates did not differ significantly between the CDC+ and FCX? groups, the 1-year estimated glomerular filtration rate was lower in the CDC+ group (P = 0.010). Infectious and significant bleeding complications occurred in 15.5 % and 4.7 % of cases, respectively. Conclusion: Kidney transplantation after desensitization had good graft outcomes and tolerable complications in Korea, and therefore, this therapy can be recommended for sensitized ESRD patients.
