Successful bone marrow transplantation in a child with combined IgG subclass deficiency and neutropenia.
An 8-year-old boy with combined IgG1 deficiency and neutropenia underwent allogeneic BMT from his HLA-identical, MLC-negative sister, because immunoglobulin (Ig) infusions and prophylactic antibiotics failed to prevent life-threatening infections. Conditioning was with busulfan and cyclophosphamide, MTX and CYA were given for the prophylaxis of GVHD. For 16 months after BMT no serious infections have occurred and serum IgG1 levels have returned to the normal range without Ig replacement. BMT may be appropriate treatment for patients with IgG subclass deficiency who rarely respond to conservative therapy.
