PATHOPHYSIOLOGICAL STUDY ON APLASTIC ANEMIA

Aplastic anemia.

PURPOSE OF REVIEW Most acquired aplastic anemia is the result of immune-mediated destruction of hematopoietic stem cells causing pancytopenia and an empty bone marrow, which can be successfully treated with either immunosuppressive therapy or hematopoietic stem-cell transplantation. RECENT FINDINGS In aplastic anemia, oligoclonally expanded cytotoxic T cells induce apoptosis of hematopoietic ...

ALLOGENIC BONE MARROW TRANSPLANTATION IN APLASTIC ANEMIA

Eighteen patients, twelve men and six women, with aplastic anemia underwent allogenic bone marrow transplantation (BMT) from HLA-matched siblings during the period of 1990 to 1996. The conditioning regimen was cyclophosphamide with or without busulfan, depending on the cause of aplasia. Antilymphocyte globulin (ALG) and cyclosporine were used for rejection and acute GVHD prophylaxis, respe...

Low drug attributability of aplastic anemia in Thailand. The Aplastic Anemia Study Group.

From 1989 to 1994, a population-based, case-control study of aplastic anemia was conducted in Thailand, including the regions of Bangkok, Khonkaen in the northeast, and Songkla in the south. An annual incidence in Bangkok of 3.7 cases per million population, about twice as high as in Western countries, has been reported. To evaluate the etiologic role of drugs, 253 subjects were compared with 1...

Aplastic Anemia - Diagnos tics and Therapy of Acquired Aplastic Anemia

Treatment of Aplastic Anemia.

There is general agreement that in children and adolescents with an HLA-identical or syngeneic sibling, bone-marrow transplantation (BMT) should be performed without delay. More controversial are young-to-middle-aged adults with an HLA-identical sibling. Because of comparable survival rates, some centers advocate BMT; others advocate immunosuppression as primary treatment. BMT cures severe apla...
