In addition to our center (Northwestern University, Chicago), several institutions in the United States (Fred Hutchinson Cancer Center, University of California at Los Angeles, and Medical College of Wisconsin) and Europe are activating protocols to transplant patients with SADS. In this age of cost-effectiveness, it will be difficult to arrange third-party reimbursement for a hematopoietic stem cell transplant that may lead to medical charges of between $100,000 and $200,000. However, the cost of standard medical care for patients with SADS is not trivial. Dialysis for an SLE patient with renal failure costs $40,000 per year, while the medical resources required to care for a patient with progressive multiple sclerosis may exceed $35,000 per year. Unique BMT regimen-related toxicities may occur, including intracranial hemorrhage in the SLE or rheumatoid arthritis patient who has vasculitis; acute neurologic decompensation in patients with multiple sclerosis, especially if the conditioning regimen contains neurotoxic agents that cross a compromised blood-brain barrier; respiratory failure in patients with myasthenia gravis; and increased renal or pulmonary toxicity in patients with scleroderma and parenchymal fibrosis. Scleroderma-associated gastrointestinal dysmotility and bacterial overgrowth may also lead to greater fungal and bacterial infections [76]. BMT is currently considered appropriate therapy for patients with chronic-phase Chronic myelogenous leukemia (CML) and indolent lymphomas who otherwise have a relatively long life expectancy of 5 and 10 years, respectively. The roughly similar long survival but greater functional impairment of patients with SADS may justify consideration of immune ablation and hematopoietic stem cell rescue.

With over 4 decades of seminal contributions to the development and application of BMT, Dr. Thomas stresses the importance of collaboration between rheumatologists and transplant clinicians in developing this evolving area of treatment. While the debate concerning the value of TBI in the conditioning regimen and the use of autologous or allogeneic stem cells will continue, he states there is simply no other way to answer these questions than to begin well designed clinical studies. As pointed out by Dr. Hahn, unexpected post-transplant complications may arise in patients with SSc and SLE and possibly require modifications to the transplant procedure similar to the experience in patients with other specific diseases. Other difficulties may be encountered, including restricted funding of the transplant procedure by insurance carriers. The emergence of managed care contracts and payer limitations in the United States described by Dr. Appelbaum could hinder the development of innovative, curative therapies. As initial clinical data are being collected, it is vital to actively support patient referral and participation in clinical studies that will ultimately establish the indications, risks, costs, and benefits of hematopoietic stem cell transplantation for autoimmune disease.
