OBJECTIVES: We aimed to evaluate the safety and long-term efficacy of autologous peripheral blood haematopoietic stem cell transplantation (APHSCT).
METHODS: We did not want to evaluate the efficacy of antibodies but rather the clinical response by investigating progression-free survival and serologic response by assessing autoantibody titres and complement levels.
RESULTS: Overall, 22 patients with SLE (17 females; median age, 23 years) undergoing APHSCT were included. The 3-year progression-free survival (PFS) was 77.27% at our centre. We found that all the patients survived over three years. The 5-year PFS and overall survival (OS) rate was 67.90% and 95.20%. The titres of antinuclear antibody (ANA), anti-double-stranded deoxyribonucleic acid antibody (anti-dsDNA), anti-Sm antibody, and 24-h urinary protein significantly decreased, while complements 3 (C3) and C4 normalised at 100 days after transplantation (p<0.05). Kidney re-biopsy revealed a decrease in immune complex deposits in patients with remission. The incidence of CMV reactivation was 59.09% after transplantation in 3 years. Pregnancy and childbirth were reported in three female patients after transplantation. The risk of post-transplantation complications persisted for many years.
CONCLUSIONS: Immunoablation followed by APHSCT has the potential to induce long-term clinical and serologic remissions despite withdrawal of immunosuppressive maintenance therapy. While relapses may occur, in our small cohort of patients we found no predictive markers for relapse development by analysing antibody and complement levels and urinary proteinuria.
