In HSCT setting, KIR-driven alloreactivity might be better predicted if the donor KIR genotype is considered in addition to the recipient HLA genotype. The prediction of NK cell alloreactivity relies on the missing ligand in the recipient, a scenario that can be found in HLA-identical and non-identical allotransplants. The aim of this study was to investigate at genetic level the prognostic impact of recipient HLA-I lacking for donor KIR on allotransplanted patients outcome. We analysed donors KIR genotype and HLA genotype of 60 paediatric patients who received related (n=15) or unrelated (n=45) transplantation. When patients were grouped based on the KIR gene type involved in the KIR/HLA-I mismatch, we did not observe any relapse in the group of patients characterized by mismatches involving only inhibitory KIR. On the contrary, all relapses were observed in patients showing at least one activating gene involved in the mismatch (p<0.05). Although the biological mechanism accounting for this putative genetic rule is still to be clarified, we suggest that a careful survey of KIR/HLA-I mismatching should be taken into account in the selection of donor in related and unrelated HSCT.
