Long-term follow-up of autologous peripheral blood hematopoietic stem cell transplantation for refractory lupus nephritis-a series study of 20 patients
BACKGROUND: Autologous hematopoietic cell transplantation (ASCT) improves immunologic homeostasis in autoimmune diseases. ASCT-treated refractory lupus nephritis (LN) has been reported. Nevertheless, the long-term outcome of patients with refractory LN after ASCT remains unknown. This study reports the outcomes of 20 refractory lupus patients with 10-year of follow-up after receiving ASCT.
METHODS: Twenty-two patients with LN refractory to immunosuppressive therapy were enrolled. Twenty patients were examined closely and two cases died within 100 days after ASCT. Hematopoietic cell mobilization with cyclophosphamide and granulocyte colony-stimulating factor (G-CSF) was followed by collection of CD34+ positively selected cells. The conditioning regimen consisted of intravenous cyclophosphamide, rabbit antithymocyte globulin, methylprednisolone, and G-CSF. All immunosuppressive therapies were discontinued at the start of mobilization and corticosteroids were tapered rapidly after ASCT.
RESULTS: Data was collected from 22 patients with refractory LN treated by ASCT. 59% were female, duration of lupus before ASCT was 46 (33-71) months, and median duration of follow-up after ASCT was 89.5 (56-108) months. 20 long-term followed up patients had an average follow-up time of 92 months (63.25-109.5). Eighteen patients achieved complete remission, one patient reached partial remission, one patient without remission started peritoneal dialysis at month 12, and one patient received short-term renal replacement therapy before ASCT started hemodialysis at 84 months after transplantation. Nine patients relapsed 10 times during the follow-up, and three patients received rituximab. Two patients relapsed during pregnancy after complete response and the Apgar scores of infants were 9 and 10, respectively. All nine patients received glucocorticoids and immunosuppressive medication after relapse and responded again. The 10-year overall survival, 10-year disease-free survival rate, and 10-year renal survival were 100%, 35%, and 90%, respectively. The rate of relapse was 45%. Complications included hypocytosis, infection, B-type insulin resistance syndrome, and monoclonal immunoglobulinemia.
CONCLUSION: This study suggests ASCT is effective and safety in treating refractory LN and is beneficial to improve their long-term outcomes.
