A31-year-old woman with advanced acute myeloid leukemia underwent non-T-cell-depleted (TCD) peripheral blood stem cell transplantation (PBSCT) with a reduced-intensity conditioning regimen. The donor was an HLA haploidentical 3-loci-mismatched complementary sibling who had not inherited maternal HLA antigens. Long-term fetomaternal microchimerism was detected by nested polymerase chain reaction with specific primer typing. Graft-versus-host disease (GVHD) prophylaxis consisted of tacrolimus with minidose methotrexate. Durable engraftment was achieved without severe acute GVHD, and complete remission was obtained. Thus non-TCD HLA haploidentical reduced-intensity PBSCT based on fetomaternal immunological tolerance appears to be feasible. Our results have important implications in the selection of alternative donors and conditioning regimens for allogeneic hematopoietic stem cell transplantation.
