title: Immunoreconstitution in severe combined immunodeficiency after transplantation of HLA-haploidentical, T-cell-depleted bone marrow.
abstract: Immunological reconstitution by transplantation of HLA-haploidentical, paternal bone marrow was attempted in four infants with severe combined immunodeficiency who lacked HLA-identical donors. To prevent graft-versus-host disease, T lymphocytes were removed from the grafts by agglutination with soybean agglutinin and rosette formation with sheep red blood cells. None of the patients received conditioning treatment before transplantation. Normal, donor-derived cellular immune functions developed in all four patients within several months of transplantation. Threatening complications of graft-versus-host reactions were not seen. All four patients remain in excellent health 12-15 months after discharge home, with persisting normal T-cell functions.
