Lupus diagnosis: Four of the ACR criteria,19,20 four of the SLICC criteria,21 and/or the recent ACR/EULAR criteria, which requires an ANA of 1:80 or greater plus a score of 10 points.
* If the patient had previous kidney disease (documented UCPR \>0.5 as part of ACR, SLICC or EULAR criteria and preferably a biopsy such that Class can be recorded), the patient is now in clinical remission as defined by a UPCR \<0.3 at the current visit regardless of any serologic activity. Relapse rates of lupus nephritis occurs in approximately one-third of patients.
* If no history of previous kidney disease, diagnosis of SLE within 5 years of the current visit, a positive anti-dsDNA and or low C3 or C4 levels, and current UPCR \<0.3. These parameters were chosen since the development of lupus nephritis is generally within the first years of SLE diagnosis,1-3 and often patients have serologic activity antedating clinical proteinuria.210
