BACKGROUND AND OBJECTIVES Although acquired aplastic anemia is usually a chronic disorder, a small proportion of patients with aplastic anemia was reported to recover spontaneously without specific therapy such as allogeneic bone marrow transplantation or immunosuppressive treatment. We attempted to determine the rate of spontaneous remission in the patients with AA. DESIGN AND METHODS We rev...

Aplastic anemia (AA) may evolve into clonal diseases like myelodysplastic syndrome (MDS) and acute myeloblastic leuke¬mia (AML). Monosomy 7 is a poor prognostic chromosomal abnormality commonly associated with therapy related MDS and secondary AML. It has also been associated with leukomogenic transformation in AA. We present here two adult ma¬le patients with acquired severe AA. Both patients ...

Cord blood transplantation has been used extensively in the allogeneic setting for acquired and genetic disorders of hematopoiesis. There is less experience in the utility of autologous cord blood transplantation, and there is great controversy about the role of autologous cord blood collection and storage. We report on the successful use of autologous cord blood transplantation for the treatme...

Hepatitis-associated aplastic anemia is an uncommon variant seen in young, previously healthy individuals. The pancytopenia follows hepatitis by a few weeks and is usually severe and prolonged. Bone marrow transplantation remains the cornerstone of therapy. However, immunosuppressive therapy has been found to be effective. We report an 8-year-old girl who had non-A, B, C and E hepatitis-associa...

Aplastic anemia therapy remains difficult, due to lack of effective treatment regimens. In recent years, Huangqi injection for the adjunctive therapy of aplastic anemia has been reported in many clinical trials. Considering that Huangqi injection may be a novel approach to aplastic anemia treatment, we conducted a meta-analysis of clinical controlled trials to assess the clinical value of Huang...

We carried out chromosomal analysis of a 33-year-old male who was diagnosed as having aplastic anemia. The patient showed severe pancytopenia, a normal NAP score, hypoplastic marrow and no myelodysplastic changes. 45,XO was found in all bone marrow cells examined, and in 10% of peripheral blood cells examined. To our knowledge, this is the first reported case of male aplastic anemia to show los...

Fas/FasL protein expression of bone marrow hematopoietic cells was investigated in severe aplastic anemia (SAA) patients. Fas expression was evaluated in CD34(+), GlycoA(+), CD33(+), and CD14(+) cells labeled with monoclonal antibodies in newly diagnosed and remission SAA patients along with normal controls. FasL expression was evaluated in CD8(+) cells in the same manner. In CD34(+) cells, Fas...

Aplastic anemia is a relatively uncommon disease and conventional management options include immunosuppressive drugs and/or haematopoeitic stem cell transplantation. It is now known that the pathogenesis of aplastic anemia is immune mediated. Mycophenolate mofetil is a common immunosuppressive drug now used mainly in prophylaxis of graft rejection in organ transplant and also for prevention/tre...

Overall survival in severe aplastic anemia has markedly improved in the past four decades due to advances in stem cell transplantation, immunosuppressive therapies and supportive care. Horse anti-thymocyte globulin plus cyclosporine is the standard immunosuppressive regimen in severe aplastic anemia, and often employed as initial therapy as most are not candidates for a matched related stem cel...
