Characteristics of lupus nephritis

Lupus nephritis is a severe manifestation of lupus.1

By the time lupus nephritis is diagnosed, kidney damage may already be severe1

Up to 5 of the next 10 patients with lupus a doctor sees may develop lupus nephritis2

31%–48% of patients will develop lupus nephritis at some point after their initial lupus diagnosis.2*

Once diagnosed with lupus nephritis, patients are

45X

more likely to develop ESKD3

(HR=44.7; 95% CI, 6.1–329.7)

Progression to lupus nephritis increases patient risk of death by

3X3

(HR=3.2; 95% CI: 1.6–6.5)

* Data from a pragmatic review of 26 publications involving patients with lupus nephritis with or without a proven biopsy.

† Adjusted risk of kidney failure and death once diagnosed with lupus nephritis. Analysis of SLICC inception cohort of newly diagnosed patients enrolled between 1999 and 2012, and who were followed for a mean of 4.6 years. A total of 1827 patients were recruited, of whom 700 (38.3%) had lupus nephritis over the course of the follow-up. The estimated cumulative incidence of ESKD (as defined by the SDI) for the entire cohort at 10 years following enrollment was 4.3% (95% CI: 2.8%, 5.8%). For all patients with lupus nephritis, the [estimated] cumulative incidence of ESKD at 10 years after the diagnosis of lupus nephritis was 10.1% (95% CI: 6.6%, 13.6%). The estimated cumulative incidence of death from all causes for the entire cohort at 10 years after enrollment was 4.4% (95% CI: 2.7%, 6.1%). For patients with lupus nephritis, the [estimated] cumulative incidence of death at 10 years following the diagnosis of lupus nephritis was 5.9% (95% CI: 3.3%, 8.4%). Nephritis was identified by the renal disorder variable of the ACR classification criteria and/or biopsy evidence of nephritis as per the ISN/RPS criteria. Cox regression analysis that adjusted for gender, age at enrollment, and race/ethnicity.3

ACR = American College of Rheumatology; CI = confidence interval; ESKD = end-stage kidney disease; HR = hazard ratio; ISN/RPS = International Society of Nephrology/Renal Pathology Society; SDI = SLICC/ACR Damage Index; SLICC = Systemic Lupus International Collaborating Clinics.

With each renal flare, there is irreversible nephron loss – shortening the kidney’s life span and increasing the risk of ESKD1

It is critical to reduce the number of renal flares to prevent progression to ESKD and the need for dialysis1,5

45% of patients with lupus nephritis experience renal flares despite receiving immunosuppressive
therapy1,6

‡ Renal flares are defined as a rise in serum creatinine level and/or proteinuria, abnormal urinary sediment, or reduction in creatinine clearance.1,5

CKD = chronic kidney disease; GFR = glomerular filtration rate.
