Abstract
Autoimmune diseases (AID) result from the impairment of the effector and/or recognition phase of the immune response. The autoimmune process plays a crucial role in the pathogenesis of the systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA), and their treatment is therefore largely based on immunosuppression.
However, some patients do not respond to its standard doses. The disease becomes intractable with the survival rate comparable to that of some haematological malignancies, or patients become soon handicapped with very poor quality of life, depending on continual administration of high doses of steroids.
The new hope for those patients becomes therapy with high dose myelo- and immuno-ablative chemotherapy with autologous hematopoietic progenitor cell support (PBPC). Tens of patients with intractable forms of AID were transplanted in the pilot clinical studies with promising results.
The most frequent indications included: SLE, SSc, and RA. Final conclusion of the therapeutic effects will be drawn from the analysis of larger trails.
