[Bone marrow transplantation in the treatment of autoimmune diseases. ISAMAIR Group]

EXPERIMENTAL BASIS AND CLINICAL OBSERVATIONS: Remission of an autoimmune disease has been observed in certain patients after bone marrow allograft from a healthy donor. Autoimmune disease in the donor can also be transmitted to an unaffected recipient. These phenomena would be hematopoietic-dependent. BONE MARROW ALLOGRAFTS: Indications for the treatment of refractory autoimmune diseases are exceptional due to the related mortality even in patients without malignant hematologic disease. A NEW THERAPEUTIC CONCEPT: Therapeutic intensification, followed with autologous peripheral stem cell grafts, a procedure with a mortality below 3% in 1997, constitutes a therapeutic alternative in these difficult indication concerning severe refractory autoimmune diseases including: sclerodermia, vasculitis, lupus, inflammatory myositis, autoimmune cyopenia.
