Our aims were to evaluate efficacy and tolerance, and to analyze predictive factors for response and survival. Recent results in children are more favorable.25 Perhaps due to the poor prognosis, unrelated BMT has been performed mostly in patients refractory to IS, raising the question whether early transplantation would result in better outcomes. 8. BMT offers a truly curative treatment alternative in contrast to the long-term complications of conservative IS therapy, including evolution to MDS and a high relapse rate. Consequently, treatment failures may reflect under-dosing and there is little guidance as to rational dose adjustment and modification. Syngeneic transplantation in aplastic anemia: pre-transplant conditioning and peripheral blood are associated with improved engraftment: an observational study on behalf of the Severe Aplastic Anemia and Pediatric Diseases Working Parties of the European Group for Blood and Marrow Transplantation. Would you like email updates of new search results? While the low numbers of reported patients preclude generalization, no individual abnormality predicted unresponsiveness.

Infusion of haploidentical hematopoietic stem cells combined with mesenchymal stem cells for treatment of severe aplastic anemia in adult patients yields curative effects. In one study of patients refractory to horse ATG, rabbit ATG resulted in a 50% response rate and excellent long-term survival.13 No good prognostic factors are available with regard to the response to ATG with the exception of the presence of HLA-DR*15 alleles and PNH clones, which both correlated with responsiveness to IS4 but the correlation was not absolute. After first-line therapy, 32% of patients achieved a complete response, and 15% a partial response. Gerull S, Stern M, Apperley J, Beelen D, Brinch L, Bunjes D, Butler A, Ganser A, Ghavamzadeh A, Koh MB, Komarnicki M, Krger N, Maertens J, Maschan A, Peters C, Rovira M, Sengelv H, Soci G, Tischer J, Oneto R, Passweg J, Marsh J.

Refractory patients may be retreated with multiple courses of ATG, which may result in salvage of a significant proportion of patients. It is most common in children and younger adults. It remains unclear whether moderate AA represents a separate entity, a number of nosologic entities such as familial bone marrow failure syndromes, or a stage of typical AA. For selected patients BMT may be a viable treatment option. With today's standard treatments, around 7 of every 10 patients with aplastic anemia improves. Your risk increases if you: Are exposed to toxins Take certain medicines Have a disease such as hepatitis or HIV What are the symptoms of aplastic anemia? Even better results were reported in children, in whom BMT appears to be more effective in improving survival than IS.27,Table 5 summarizes recently reported results.18,26,28,30 However, a typical decrease in the overall survival is observed with increasing age of the recipient, making the therapeutic decision for older patients a challenge. All but 2 deaths were related to AML.33 Response to IS in patients with aplasia and an abnormal karyotype may be as high as 50%,34 and certain karyotypic abnormalities (Trisomy 8, 13q) may favorably respond to IS. In contrast, 75% of the responses to ATG are within the first 3 months, and relapses occur within 1 year following ATG therapy.24.
