Reduction of joint damage in severe rheumatoid arthritis by high-dose chemotherapy and autologous stem cell transplantation.Verburg RJ, Sont JK, van Laar JM Leiden University Medical Center, Leiden, The Netherlands. r.j.verburg@lumc.nl <r.j.verburg@lumc.nl> OBJECTIVE: To examine the influence of high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) on joint damage in patients with rheumatoid arthritis. METHODS: Eight patients with active, refractory, progressively erosive RA were treated. The conditioning regimen consisted of intravenous administration of high doses of cyclophosphamide (totaling 200 mg/kg), with subsequent reinfusion of the positively selected graft. Radiographs of hands and feet were obtained before, and at 1 and 2 years after transplantation. All radiographs of hands and feet obtained up to 6 years before transplantation were also collected to compare radiographic progression before and after HDC + ASCT. Scoring of all radiographs was performed according to the Larsen scale by a trained investigator who was blinded with regard to the clinical data. RESULTS: Radiographic assessment by the Larsen scale showed a decreased progression of joint damage. Before transplantation, the mean Larsen score increased at a rate of 8.9 points per year. During the 2 years after transplantation, the mean rate of progression in the Larsen score decreased to 2.7 points per year (P = 0.023 by paired t-test). CONCLUSION: The results of the present analysis demonstrate major beneficial effects of HDC + ASCT on the rate of joint destruction during the first 2 years of followup after treatment.
