Appearance of multiple benign paraproteins during early engraftment of soy lectin T cell-depleted haploidentical bone marrow cells in severe combined immunodeficiency.

Journal Article (Journal Article)

Recent advances in the prevention of graft-versus-host disease through postthymic T-cell depletion have allowed the use of haploidentical bone marrow cells for immunologic reconstitution of severe combined immunodeficiency disease. We report a male infant with severe combined immunodeficiency (with normal adenosine deaminase) who developed two IgG kappa and one IgA lambda paraproteins 7 weeks following the administration of 1.4 X 10(9) maternal bone marrow cells depleted of postthymic T cells by soy lectin agglutination and sheep erythrocyte rosetting. Serum IgG rose from 128 to 820 mg/dl, and IgA from 0 to 2400 mg/dl, peaking at 10 weeks postgrafting. By 14 weeks posttransplantation T-cell numbers and function had risen to normal (all dividing T cells had the donor karyotype) and paraprotein concentrations began to decline. These observations strongly suggest that the later-appearing T cells regulated the B-cell clones from which the paraproteins were derived. Failure of such function to appear could account for the increased incidence of B-cell lymphomas in severe combined immunodeficiency.
