Prognostic role of KIR genes and HLA-C after hematopoietic stem cell transplantation in a patient cohort with acute myeloid leukemia from a consanguineous community.
Bone Marrow Transplantation 2018 September
NK cell activity is tuned by a balance of activating and inhibitory signals transmitted via their respective receptors, including killer immunoglobulin-like receptors (KIRs). The impact of NK cells on graft-versus-leukemia following hematopoietic stem cell transplantation (HSCT) is well established. These effects sometimes lead to GvHD. The link between KIR/HLA interaction and GvHD remains unclear. Herein, we studied the impact of the KIR/HLA interaction on HSCT outcomes in a longitudinal follow-up study of a highly consanguineous HLA-matched related cohort. Peripheral blood DNA was collected from HSCT donor-recipient pairs (n = 87), including 41 AML pairs. KIR and HLA were genotyped and significant results were only measured when matching KIR (donor) with HLA (recipients). GvHD was observed in 47% of patients. KIR2DL1_C2 and 2DS2_C1 (P = 0.02 and 0.04, respectively) matching was associated with an increased incidence of acute GvHD in AML donor-recipient pairs. The rate of chronic GvHD also rose in AML patients who were matched for KIR2DS1_C2 (P = 0.004) and had either KIR2DL2 or KIR2DS2 (P = 0.03). In conclusion, matching of KIR2DL1, 2DS1, and 2DS2 in donors with their HLA-C ligands in recipients is associated with increased GvHD, and holds potential for selection of HSCT donors.
