Complete remission in a case of aplastic anemia after treatment with antilymphocyte globulin

The Authors report a case of aplastic anemia, resistant to treatment with androgens and prednisone, in which bone marrow regeneration was observed after treatment with antilymphocyte globulin.This observation confirms the possibility of a immune pathogenesis in some cases of aplastic anemia, although no direct evidence was obtained supporting the existence of a humoral or cellular autoimmune process in the patient.The result obtained points to a new approach in the treatment of aplastic anemia.
