C
60
3 topical GC side effects (these are typically with long term use)
skin atrophy rosacea telangiectasis -> blood vessels more shallow

treatment for severe lupus nephritis
MMF (preferred) * OR CYC +/- GC could also consider triple therapy being: Belimumab + MMF or CYC +/- GC or CNI + MMF +/- GC wtf
95
review slide 61 with someone smart
this is a call for help
96
The best prognosis is when the patient achieves remission for ≥ _ months before pregnancy
