Successful transplantation of soy bean agglutinin-fractionated, histoincompatible, maternal marrow in a patient with severe combined immunodeficiency and BCG infection.

A successful transplantation of soybean agglutinin (SBA) and sheep red blood cell (SRBC)-fractionated, maternal marrow in a patient with severe combined immunodeficiency (SCID) is reported. The engraftment of HLA-haplotype mismatched marrow cells was obtained without apparent graft versus host disease (GVHD). With immunological reconstitution the patient recovered from a BCG infection, which might have been caused by a BCG inoculation before his bone marrow transplantation.
