Infection and bleeding are major causes of morbidity and mortality from aplastic anemia. Patients who undergo HCT have additional issues related to acute and chronic toxicity from the conditioning regimen and graft versus host disease (GVHD), as well as a potential for graft failure. [23, 46, 47, 48, 49, 50]

In approximately 25-30% of patients with aplastic anemia, the condition does not respond to immunosuppression. In cases with a treatment response, relapse and late-onset clonal disease, such as paroxysmal nocturnal hemoglobinuria (PNH), myelodysplastic syndrome (MDS), and leukemia, are risks—regardless of the treatment response or degree of response. [19, 51, 52, 53, 54]
