If bone marrow transplantation is to become widely applicable in the treatment of patients with leukemia and aplastic anemia, the necessity to have a perfectly histocompatible donor must be overcome. In an effort to define the roles of HL-A type and mixed lymphocyte culture (MLC) reactivity in the determination of successful engraftment and the occurrence of graftversus-host disease (GVHD), we have attempted transplantation of a child with acute myeloblastic leukemia (AML) using an HL-A identical, MLC-reactive sibling donor. Successful engraftment has been accomplished, as documented by the appearance of multiple donor genetic markers in the recipient. There is no evidence of severe GVHD. The recipient is alive, without evidence of leukemia, and has returned to full activities 9 mo after transplantation. The recipient now produces lymphocytes, which have the MLC reactivity that characterize the donor's lymphocytes, rather than that of her own pretransplant lymphocytes. This experience demonstrates that successful bone marrow transplantation in patients with leukemia can be accomplished in the face of MLC reactivity.

CONTEXT: Mixed lymphocyte culturing has led to conflicting opinions regarding the selection of donors for bone marrow transplantation. The association between a positive mixed lymphocyte culture and the development of graft-versus-host disease (GVHD) is unclear. The use of exogenous cytokines in mixed lymphocyte cultures could be an alternative for increasing the sensitivity of culture tests. OBJECTIVE: To increase the sensitivity of mixed lymphocyte cultures between donor and recipient human leukocyte antigen (HLA) identical siblings, using exogenous cytokines, in order to predict post-transplantation GVHD and/or rejection. TYPE OF STUDY: Prospective study. SETTING: Bone Marrow Transplantation Unit, Universidade Estadual de Campinas. PARTICIPANTS: Seventeen patients with hematological malignancies and their respective donors selected for bone marrow transplantation procedures. PROCEDURES: Standard and modified mixed lymphocyte culturing by cytokine supplementation was carried out using donor and recipient cells typed for HLA. MAIN MEASUREMENTS: Autologous and allogenic responses in mixed lymphocyte cultures after the addition of IL-4 or IL-2. RESULTS: In comparison with the standard method, average responses in the modified mixed lymphocyte cultures increased by a factor of 2.0 using IL-4 (p < 0.001) and 6.4 using IL-2 (p < 0.001), for autologous donor culture responses. For donor-versus-recipient culture responses, the increase was by a factor of 1.9 using IL-4 (p < 0.001) and 4.1 using IL-2 (p < 0.001). For donor-versus-unrelated culture responses, no significant increase was observed using IL-4, and a mean response inhibition of 20% was observed using IL-2 (p < 0.001). Neither of the cytokines produced a significant difference in the unrelated control versus recipient cell responses. CONCLUSION: IL-4 supplementation was the best for increasing the mixed lymphocyte culture sensitivity. However, IL-4 also increased autologous responses, albeit less intensively than IL-2. Thus, with this loss of specificity we believe that it is not worth modifying the traditional mixed lymphocyte culture method, even with IL-4 addition.

Abstract Constitutional pure red cell aplasia (CPRCA) is a syndrome of failed erythropoiesis usually diagnosed within the first year of life. Four patients with CPRCA received transplants with marrow from their HLA- identical, mixed lymphocyte culture-nonreactive siblings. All patients were resistant to corticosteroid therapy and were dependent on regular red cell transfusions for at least 5 years. Three patients were conditioned with procarbazine, antithymocyte globulin, cyclophosphamide, and busulfan, and one was conditioned with antithymocyte serum, cyclophosphamide, and busulfan. Three patients promptly had successful engraftments with establishment of donor hematopoiesis. One patient initially rejected his graft but received a successful retransplant. All patients are currently alive with Karnofsky performance scores of 100 and normal erythropoiesis of donor origin. Despite a history of multiple transfusions, bone marrow transplantation is a potentially curative therapy for patients with CPRCA.
