Systemic lupus erythematosus (SLE) presents clinical evidence of lupus nephritis in approximately 35% of patients
at the diagnosis, with total of 50~60% developing nephritis during 10 years of disease. The presence of lupus nephritis
significantly deteriorated the patient survival to 88% at 10 years, which is much lower survival compared with the survival
of patients without lupus nephritis.
The recent published guidelines suggested two phases of therapy for lupus nephritis class III/IV as induction and
maintenance phases. Cyclophsophamide (CYC) or mycophenolate mofetil (MMF) combined with steroid pulse followed
by high-dose steroid is recommended as the first line agents for induction therapy. To the improved patients after
induction, MMF or azathioprine with low-dose steroid is used as maintenance therapy. Although MMF and CYC are
equally effective in short-term induction, it is needed to investigate whether MMF are also effective as CYC in longterm
outcomes.
Various novel biologic agents and small molecules have been studied to treat lupus nephritis. However, many trials
in general have not succeeded in improve short-term end points. Short-term kidney response might be improved better
with anti-inflammatory therapy than anti-autoimmune therapy to which most novel agent was categorized. The optimal
approach for using novel therapeutics might be an introduction of new treatment paradigm of lupus nephritis; after
initiation of anti-inflammatory therapy, novel therapy should be administered for targeting autoimmune mechanisms |
