Abstract Background and Aims This study explores a personalized delisting strategy enabling kidney transplantation in highly sensitized patients with preformed donor-specific anti-HLA antibodies (DSA) trying to minimize the risk of antibody-mediated rejection (ABMR). Method Retrospective single-centre analysis of 50 kidney transplant recipients with preformed DSA (preDSA) after employing a delisting strategy to enhance their access to transplantation, and without received a pre-transplant or immediate post-transplant desensitization protocol. The delisting approach focused on allowing less deleterious antibodies according to their mean fluorescence intensity (MFI), anti-HLA class and C1q study results. The strategy consisted on eliminating as prohibited HLA antigens those recognized by antibodies with the lowest MFI in the following order: 1st- MFI < 5000; 2nd- MFI < 10000; 3rd-Any MFI. Additionally, delisting prioritized a single locus in the following order: 1st- one of the HLA class I loci (A, B, or Cw); 2nd- the rest of the class I loci; 3rd- HLA-DP, followed by DR. C1q studies were performed before delisting and transplantation was contraindicated in the presence of DSA detected in the C1q assay. Two comparative cohorts included 50 sensitized recipients without pre-transplant DSA (SwoDSA) and 50 non-sensitized recipients (NS). Results The delisting strategy allowed transplantation with preformed DSA and demonstrated comparable rejection rates to SwoDSA and NS groups (16%, 14% and 8%, respectively; log-rank = 0.28). However, the occurrence of acute ABMR was 12% in the preDSA group, significantly higher than in SwoDSA (1%) and NS (0%) (log-rank = 0.0093). The immunological risk assumed in delisting correlated with ABMR incidence (patients with ABMR had significantly higher sum MFI mean ± SD: 9301 ± 6340 vs 4492 ± 5641; p = 0.049), emphasizing the importance of tailored strategies. DSA persistence after transplantation correlated with higher MFI and increased ABMR risk. Of note, 16% of preDSA patients developed de novo DSA versus only the 4% of SwoDSA and 0% of NS patients (p = 0.004). After a mean follow-up of 3.1 ± 2.1 years, the 1-, 3- and 5-year death-censored allograft survival rates were 100%, 90% and 78%, respectively, in the preDSA group; 98%, 84% and 84% in the SwoDSA group and 100% in NS group (log-rank = 0.02). Conclusion The present study demonstrates the feasibility and acceptable outcomes of kidney transplantation in highly sensitized patients with preformed DSA through a personalized delisting strategy without using desensitization protocols.
