A 6 month old boy was diagnosed as a case of combined immunodeficiency (with predominant T cell defect by previous classification). His T cell count was decreased, his B cell count in peripheral blood was increased, his serum IgG level was decreased, his serum IgM level was normal and the thymus was not evident on CT scans and magnetic resonance imaging. Administration of the thymus hormone, thymosin, led to a partial recovery of T cell function without normalization of the T cell count. At age 26 months the patient received an irradiated thymus transplantation from a 16 week old female fetus. After the transplantation, the T cell count (mainly CD4+ cells) increased by 50-70%. A mild graft-versus-host reaction (GVHR) occurred and several immunosuppressants were prescribed. Chromosome analysis showed that the T cells have both 46 XY and 46 XX karyotypes while the B cells have the 46 XY karyotype alone. His cellular immunity (skin tests, DNA synthesis, mixed lymphocyte reaction, cytotoxic activity and natural killer cell function) and his serum IgG level remained low. However, being on regular r-globulin therapy and oral anti-fungal drugs, he is now living normally with almost no trouble at age 6 years and 3 months. This case showed that irradiated thymus transplantation might be a useful method when an adequate donor for bone marrow transplantation is not available. The unexpected observation that the increased T cells were mainly CD4 may be related to the mild GVHR and the clinical improvement.
