HLA 0MM DD transplants have superior outcomes compared with outcomes for grafts with ≥1 HLA mismatches, but when past reports analyzed 0MM outcomes in DD, they pooled together recipients with low and high panel reactive antibodies (PRA). Recent studies have questioned the benefit of 0MM transplants in highly sensitized recipients due to their immunological disadvantages. Aim of study: Investigate the outcome of 0MM transplants in the highly sensitized recipients. Methods: Data were retrospectively analyzed from 253 recipients who received HLA-A, -B, -DR 0MM deceased-donor (DD) kidney only transplant in our Institute (1990 – 2012). The study population were classified into 3 groups according to the pre transplant cPRA; I) cPRA 0 (57%), II) 1-79 (32%), and III) ≥ 80(11%). The clinical end points compared were the incidence of biopsy proven acute graft rejection (BPAR), graft loss, and patient death. KM graphs and Cox models were used for statistical analysis. Results: The 3 groups were comparable in terms of age, gender, and race. Mean follow up was 7.1 (±4.4)years. History of previous kidney transplantwas noticed in 18.8, 25.9, and 35.6% resp (p=0.4). 5 years BPAR rate was 12.5, 12.5, and 17.8% resp (Log rank 0.05). 5 years graft survival was 75.6, 70.3, and 85.7% resp- (Log Rank 0.4), and patient survival was 62, 70, and 75% resp (Log Rank 0.7). 5 years SCr was 2, 2.5, 2.1 resp (p = 0.9). Conclusion: Highly sensitized recipients showed a trend toward higher incidence of BPAR, however, patient and graft survival as well graft function were not worse compared to non and low sensitized recipients. Highly sensitized recipients do benefit from the 0MM DD grafts, however prospective national data studies are warranted.,
