The role of high dose chemotherapy and autologous peripheral blood progenitor
cell (PBPC) transplant as treatment for severe autoimmune diseases, particularly
rheumatoid arthritis, is currently the subject of considerable debate In this
report we describe a man with severe adult-onset Still's disease who was treated
with high dose chemotherapy and syngeneic PBPC transplantation.
A 38 year old identical twin presented with a seven year history of severe
adult-onset Still's unresponsive to salazopyrine, methotrexate, methotrexate
plus azathioprine and intramuscular gold and resulting in erosive destruction of
wrist, ankle and shoulder joints and the persistent use of steroids. In March
1997, the affected twin consented, after prolonged discussion of the potential
risks and benefits of the procedure, to undergo a syngeneic PBPC transplant.
PBPCs were harvested from the unaffected twin after treatment with filgrastim.
The affected twin was conditioned with cyclophosphamide and antithymocyte
globulin (ATGAM) and haematopoietic rescue achieved with 2.59 × 106 CD34 +
cells/kg from his unaffected brother. The transplant was complicated by a rash
and a fever. The patient was discharged 14 days after the transplant and
returned to regular exercise and fulltime work within 6 weeks. Eighteen months
after the transplant the patient remains in complete remission with no swollen
joints and a normal C-reactive protein. Prior to the PBPC transplant the twins
circulating T lymphocyte Vb repertoires were distinctly different whereas after
the transplant the affected twin, now in complete remission, has a Vb repertoire
identical to that of the unaffected twin.
The use of high dose chemotherapy and autologous PBPC transplantation has
recently been reported in three patients with severe rheumatoid arthritis,
scleroderma and systemic lupus erythematosus. Our case is the first description
of a prolonged remission in a patient with previously treatment-resistant
adult-onset Still's disease after high dose chemotherapy and syngeneic, rather
than autologous PBPC transplantation. The use of PBPCs from a genetically
identical individual without autoimmune disease may increase the likelihood of
"cure".
