Severe combined immunodeficiency with natural killer-cell predominance: abrogation of graft-versus-host disease and immunologic reconstitution with HLA-identical bone marrow cells.

Journal Article

A 3 1/2-month-old infant with severe combined immunodeficiency was found to have an unusual blood lymphocyte phenotype. Thirty percent of her cells formed rosettes with sheep erythrocytes, but only 7.9% reacted with the pan T monoclonal antibody OKT3, and 5% reacted with an antibody (OKT4)-recognizing T-helper cells. Surprisingly 19.4% of her cells reacted with an antibody (OKT8)-recognizing T-suppressor cells and 94% reacted with OKT10 . Few reacted with other monoclonal antibodies detecting cellular activation antigens. Despite absence of T or B cell function, her monocyte-depleted blood lymphocytes caused a high degree of specific lysis of 51Cr-labeled K562 erythromyeloid cells in a natural killer-cell assay. Most of her lymphocytes were large and had azurophilic granules and a monocytoid nucleus. Because she had received a nonirradiated, unrelated red-cell transfusion 3 days earlier, 4.8 X 10(9) nucleated bone-marrow cells from her HLA-identical brother were given shortly after admission. Two days later a graft-versus-host reaction began but subsided completely within 3 days. On day 15 posttransplantation, a profuse secretory diarrhea began, accompanied by a rise in her serum IgE from 4 to 3000 IU. With engraftment, the number of T10+ cells and natural killer-cell function fell to normal, and full immunologic reconstitution was achieved.
