A Case of Severe Aplastic Anaemia Successfully Treated by Retransplantation from the Same Donor

Sixteen (11%) of 146 consecutive patients with severe aplastic anemia prepared for engraftment with cyclophosphamide (200 mg/kg) rejected marrow grafts from their HLA-identical siblings. They were given a second marrow transplant from either the same (n = 13) or a second (n = 3) HLA-identical sibling between 23 and 743 (median 86) days after the first transplant. The preparation for the second transplant included cyclophosphamide, 50 mg/kg, on each of four successive days. Twelve hours after each of the first three doses of cyclophosphamide, antithymocyte globulin, 30 mg/kg/dose, was infused. One of the 16 patients died from infection too early after the second transplant to be evaluated, two had failure of engraftment and died with infection, one rejected the second graft and is surviving almost 5 years later with full autologous marrow recovery, and 12 had successful and sustained second grafts. Of these 12, six are surviving between 11 months and 7 3/4 years. Four of the six have no graft-v-host disease (GVHD), while two have chronic GVHD requiring treatment. Five have Karnofsky scores of 100% and one of 90%. Six of the 12 patients with sustained grafts died between 63 days and 38 months after transplantation, four with infections (related in two patients to chronic GVHD), one with acute GVHD, and one with hemorrhage. The average interval from first to second transplant was 308 days during the past five years, compared to 61 days in earlier patients. Five of seven recent patients are surviving, compared to two of nine earlier patients. In conclusion, successful second transplants after cyclophosphamide and antithymocyte globulin are possible in most patients with aplastic anemia who have rejected their first marrow grafts; however, mortality remains high, with only 40% of the patients becoming long-term survivors.

Between 1985 and 1989, eight children underwent two successive bone marrow transplantations. The initial disease was chronic myelomonocytic leukemia in three patients, chronic myelocytic leukemia in two, acute M7 nonlymphoblastic leukemia in one, sickle cell anemia in one, and thalassemia major in one. The preparation in view of the second grafting included high-dose chemotherapy in all patients, associated with antithymocytic globulin transfusion and total nodal irradiation in three patients. Hematological recovery was similar after both graftings. Infectious complications were not more common following the second graft than after the first one. On the other hand, the rates of rejection and graft-versus-host disease were lower, probably due to a more intensive immunosuppressive therapy. The prognosis of chronic leukemia relapsing after a first graft does not seem to be improved by a second attempt.
