Abstract: |
Mathé et al. reported in 1970 that when some patients with aplastic anemia received an allogeneic marrow transplant together with a conditioning immunosuppressive regimen of antilymphocyte globulin, they recovered autologous hematopoietic function.1 Subsequent trials of antilymphocyte globulin or antithymocyte globulin, alone or with steroids, resulted in hematologic improvement in 40 to 80 percent of patients with severe aplastic anemia. This effect was matched by improvement in one-year survival, from less than 25 percent with androgens alone to 40 to 75 percent with antilymphocyte globulin2 3 4 5 6 — a rate comparable to the 60 to 80 percent survival with transplantation of bone marrow. © 1991, Massachusetts Medical Society.
