Immunosuppression in SLE must be adjusted to the current Level of dise
ase activity. The spectrum of established treatment principles ranges
from no treatment or non-steroidal antirheumatic drugs alone, to gluco
corticoids, hydroxychloroquine, azathioprine and, finally, cyclophosph
amide (Ctx). Repeated pulses of intravenous Ctx can be regarded today
as established treatment for severe SLE manifestations. Administered i
n combination with prior plasmapheresis, pulse Ctx has led to long-ter
m treatment-free remission in some patients. Additional treatment opti
ons, whose potential benefits remain to be defined, are cyclosporine A
, methotrexate, highdose intravenous immunoglobulins and immunoadsorpt
ion. Possibly, high dose chemotherapy with autologous stem cell rescue
might become a future treatment option. This review describes present
knowledge regarding immunosuppression in SLE, especially the differen
tiated application of Ctx in severs SLE, and discusses the prospects f
or future development.
