Learning objectives
• To highlight the natural history of SLE
• To develop a clinical approach to patient suspected
to have SLE
• To define your therapeutic strategies to each SLE
patient based upon activity, severity, organ damage,
and comorbidities

* Not recommended in SLE if on immunosuppressive or biologic medications, low immunoglobulins, hypocomplementemia
Conclusions “take home massages”
• SLE is a heterogeneous multisystem disease which
varies among races and ethnicities
• SLE pathogenesis is complex with dysregulation of
multiple arms of the immune system
• Early lupus diagnosis and disease monitoring remains
a challenge for treating physicians
• SLICC 2012 revised SLE criteria improved the
sensitivity and retained the specificity when
compared with 1997 ACR classification
Conclusions “take home massages”
• Set the treatment goals after Identifying disease
manifestations, comorbidities, distinguish activity
from chronicity and prioritize active disease
manifestations
• Use the least toxic medicine and lowest dose to
treat the most concerning disease manifestation
• Balance the treatment of active disease verses
the complications of the treatment
