摘要

According to experimental animal models and experiences of patients with coexisting autoimmune diseases, allogeneic stem cell transplantation has the potential to reestablish and maintain immunological tolerance. On the other hand, it is associated with significant treatment related mortality and may induce diverse immunological diseases by graft-versus-host reaction. Other than with severe aplastic anemia, it is not an established therapy for autoimmune diseases; it is under investigation in clinical trials and might be considered in severe, refractory immune cytopenia.
