Our main objective was to determine new factors associated with engraftment and single-unit predominance after double umbilical cord blood (UCB) allogeneic stem-cell transplantation. Engraftment occurred in 78% of cases in this retrospective study including 77 adult patients. Three-year overall survival, disease-free survival, relapse incidence, and nonrelapse mortality were 55 ± 6%, 44 ± 6%, 33 ± 5%, and 23 ± 4%, respectively.

We retrospectively analyzed the impact of permissive/non-permissive HLA-DPB1 mismatches on the outcome of 141 patients who underwent 10/10 HLA allelic-matched unrelated HSCT. Each pair was classified according to the 3 (TCE3) and 4-group (TCE4) algorithm based on DPB1 alleles immunogenicity.

The physiologic functions of NK cells appear to be regulated by diverse non-inhibitory and inhibitory receptors including the killer cell immunoglobulin-like receptors (KIR). Although human leukocyte antigen (HLA) epitope mismatches are well-known causes of NK alloreactivity, the role of KIR genes in transplantation remains to be further investigated.
