Anti-thymocyte globulin (ATG) has been used in severe aplastic anemia as a part of the conditioning regimen. Among the many kinds of ATG preparations, thymoglobulin had been found to be more effective in preventing GVHD and rejection of organ transplants. As the fludarabine based conditioning regimens without total body irradiation have been reported to be promising for BMT/PBSCT from alternative donors in SAA, thymoglobulin was added to fludarabine and cyclophosphamide conditioning to reduce GVHD and to allow good engraftment in UBMT/UPBSCT.

Primary Outcome Measures:
  • To evaluate the engraftment potential, incidence and severity of acute graft versus host disease,toxicity of conditioning regimen for UBMT in SAA. [ Time Frame: From Jan. 1. 2006 to Dec. 31. 2008. For 3 years. ]
  • To evaluate overall and EFS follow-up of 1 year after UBMT/PBSCT. [ Time Frame: From Jan. 1. 2006 to Dec. 31. 2008. For 3 years ]

Secondary Outcome Measures:
  • To evaluate chronic GVHD and immunologic recovery after UBMT/PBSCT. and the efficacy of UBMT/PBSCT before immuno-suppressive therapy with anti-thymocyte globulin in severe aplastic anemia and long term toxicity of non-TBI based conditioning [ Time Frame: From Jan. 1. 2006 to Dec. 31. 2008. For 3 years. ]
