Abstract

Autologous hematopoietic SCT (ASCT) has been investigated as salvage therapy for refractory systemic lupus erythematosus (SLE). Although immune recovery after ASCT with in vitro purging of lymphocytes has been extensively studied, little information is available about immune recovery after ASCT without in vitro purging. Therefore, we analyzed the immune recovery of a patient who successfully underwent ASCT without in vitro purging for refractory SLE. In addition to the numbers of PBL subsets, T-cell receptor rearrangement excision circles (TRECs) and the T-cell receptor repertoire diversity of both CD4 + and CD8 + T cells were sequentially analyzed. All SLE-related symptoms disappeared within 3 months after ASCT and the serum anti-dsDNA Ab became undetectable. The number of CD4 + CD45RO + memory T cells remained lower than that in healthy adult controls, but the number of CD4CD45RA nave T cells showed a rapid increase after ASCT. TRECs of both CD4 + and CD8 + T cells were strongly suppressed before ASCT, but consistently increased after ASCT. The T-cell receptor repertoire of CD8 + T cells was skewed before ASCT, but the diversity recovered after ASCT. ASCT with the reinfusion of a large number of autologous T cells did not impair the recovery of naive T cells or resetting of the immune system.
