What do you use for treatment induction in pure class V lupus nephritis with nephrotic-range proteinuria when MMF is contraindicated?  

I'll begin my response by commenting that other than an allergic reaction, which is very rare or pregnancy, there is really no absolute contraindication to MMF.

If pure class V without any proliferation, I would use rituximab or a CNI. Both of those agents are effective in non lupus membranous. Cyclophosphamide is also an option.
