Abstract |
Twenty, six children younger than 15 years with severe aplastic anemia underwent either bone
marrow transplantation or immunomodulation therapy (antilymphocyte globulin with cyclosporin A
therapy).
Six patients who had an HLA-identical sibling donor underwent bone marrow transplantation after
conditioning with cyclophosphamide, procarbazine and antilymphocyte globulin. Twenty children
who did not have an HLA-identical donor recieved antilymphocyte globulin and cyclosporin A.
The results were as follows;
1) Hematologic responses: Complete response after transplant was showed five out of six (83.3%)
and no response in one. In immunomodulation group, three out of twenty patients responded com-
pletely (15%) and five were partially (25%).
2) Complications: In the complications according to the therapy, all patients who underwent
transplantation showed acute graft versus host disease, in which two were chronic course, one died
of rejection after 1 month, and two showed herpes zoster. In immunomodulation group, there were
thrombocytopenia, hypertension, fever and serum sickness etc.
3) Causes of death: In bone marrow transplantation group, one patient who showed rejection after
1 month at transpint expired due to intracerebral hemorrhage. In immunomodulation therapy, seven
out of twenty patients died. Among them, five were hemorrhage (71.4%) due to thrombocytopenia
and two were infection. Therefore major cause of death was rejection in transplant and hemorrhage
in immunomodulation group.
Although this study is preliminary, our data suggest that bone marrow transplantation may be
more useful therapeutic modality for the patient with severe aplastic anemia than immunomodulation
therapy if there is HLA-identical sibling donor because of worst prognosis in this disease. |
