Autologous bone marrow transplantation versus alternative drugs in pediatric rheumatic diseases.
A minority of children suffering from severe rheumatic diseases are unresponsive to conventional treatments. These patients can now be managed with a variety of immunosuppressive therapies. Methotrexate is considered the first choice disease-modifying agent for adult and juvenile rheumatoid arthritis. In patients unresponsive to low doses of methotrexate, medium or high-doses can be useful. Instead of methotrexate, a recently developed immunosuppressive drug, mycophenolate-mofetil, which inhibits T- and B-lymphocyte proliferation, can be used. Another possibility for refractory rheumatic diseases, with no increase in toxicity, is combination therapy, for example methotrexate plus cyclosporine, or methotrexate plus salazopyrine or intravenous pulses of cyclophosphamide and methylprednisone. More recently two distinct inhibitors of tumor necrosis factor (etanercept and infliximab have been used successfully for intractable rheumatic diseases (juvenile idiopathic arthritis, psoriatic arthritis, spondyloarthropathies) but the follow-up is still too short to establish their long-term effectiveness. If all these treatments are unsuccessful, an autologous bone marrow transplantation can be proposed to selected patients. Interesting results have been obtained in pediatric rheumatic diseases such as juvenile idiopathic arthritis, systemic lupus erythematosus and systemic sclerosis. Further studies are required to assess the best procedures able to induce remission with a minimal risk of fatal events.
